On the whole, tourists basically concentrate on gardens in the morning. Beiqing Daily reporter saw in Yuyuantan Park that thousands of cherry blossoms have entered the flowering stage and the cherry blossom peak has arrived ahead of schedule. Under the cherry blossom tree, many children supported drawing board sketching, and many photography societies organized shadow friends on-site teaching. In the morning, the Park welcomed the height of the park, and some sections of the road appeared to be “people squattingâ€. Due to the large traffic volume in the park, the Municipal Park Management Center conducted a garden risk assessment for the parks that carried out spring visits and flower viewing activities, and enhanced security. Beiqing Daily reporter learned that Yuyuantan Park has reduced the waiting time for tourists to buy tickets and has added 30 temporary ticket windows. Handheld security inspections have been added to various gates. At the same time, 63 electronic eyes in the park have continuously monitored the activity areas of the park. . A total of more than 500 volunteers and security personnel were involved. The Beijing Botanical Garden has sent an additional 80 policemen, armed police officers, and police officers stationed in the police station to protect the safety of tourists and belongings.

The working principle of the box Filter Press is that the filter plate is arranged to form a filter chamber (both sides of the filter plate are concave, and each two filter plates are combined into one compartment filter chamber).
The principle diagram is as follows: the surface of the filter plate has pock marks and lugs to support filter cloth. There is a through hole in the center and side of the filter plate. After assembly, it forms a complete passageway, which can pass into suspension, washing water and filtrate. Each side of the filter plate is supported by a handle on the cross beam, and the filter plate is pressed by the pressing device. The filter cloth between the filter plates plays a sealing role.
Under the pressure of the feed pump, the material liquid which needs to be filtered is sent into the filter chamber, and the solid and the liquid are separated by the filter medium (according to the selection of the suitable filter cloth according to the different industries). A filter residue is formed on the filter cloth until the filter cake is filled into the filter chamber. The filtrate passes through the filter cloth and flows along the filter plate trench to the outlet of the liquid outlet at the bottom and concentrates. After filtration, washing and washing residue can be cleaned. After washing, sometimes the compressed air is added to remove the remaining washing liquid. After the filtration is finished, the filter press is opened and the filter cake is removed (the filter cake is stored between the two adjacent filter plates). The filter cloth is cleaned, and the filter is re pressed to start the next working cycle.
Filter cloth is fixed on the plate frame. This is the main form of early filter press. The main advantage of the filter press is to replace the filter cloth easily. The disadvantage is low efficiency, bad filtering effect and easy filter plate. The filter chamber of the filter press machine is made up of two adjacent sags, and the filter cloth is fixed on each filter plate and the wing filter press is fixed. The main advantage is that the efficiency is high, the effect is better, the filter plate is relatively durable (under the same condition), but the degree of automation is high, the cleaning filter cloth has automatic device, and the frequency of changing the filter cloth will not be frequent.
