Description

Technical Field

[0001] The present application relates to the field of filter presses, and in particular to an independent feeding diaphragm filter press. Background Art

[0002] Diaphragm filter press, also known as diaphragm filter press, is a filter press with an elastic membrane installed between the filter plate and the filter cloth. During use, when the feeding is completed, high-pressure fluid or gas medium can be injected into the diaphragm plate, then the entire diaphragm will bulge to compress the filter cake, thereby achieving further dehydration of the filter cake, which is usually referred to as squeeze filtration.

[0003] Existing diaphragm filter presses usually input materials from the middle of the filter plate, and the liquid is filtered and output through the channels on both sides of the filter plate, while the filter cake is retained in the chamber between the filter plate and the filter cloth. Therefore, a channel for receiving the filter cake is usually set in the middle of the filter plate, and channels for receiving the liquid are set on both sides of the filter plate, thereby realizing the separate recovery of the filter cake and the filtrate.

[0004] In the above-mentioned diaphragm filter press, the filter cake cannot fall vertically like liquid when it falls, especially in the diaphragm filter press, the filter cake has strong bonding due to further dehydration, and the filter cake can easily touch the channel for receiving the filtrate when it falls as a whole, while the filtrate and filter cake are only distinguished and separated by position and have a long independence. In some cases, the filtrate and filter cake can easily enter other channels due to splashing or touching. Utility Model Content

[0005] In order to better independently discharge solid and liquid materials so that the two are less likely to affect each other, the present application provides a membrane filter press with independent discharge.

After the filtrate is received, when the feeding box receives the filter cake, the receiving box slides again to a state where the filter cake receiving chamber is located below the filter element, thereby receiving the filter cake through the filter cake receiving chamber. The filter cake and filtrate are received relatively more independently. Compared with simultaneously setting channels for receiving the filtrate and the filter cake, the filter cake receiving chamber has a larger receiving area, and the filter cake is less likely to scatter.

By arranging a reinforcing column in the middle of the length direction of the frame, the frame is better supported. Two material boxes are arranged, so that the reinforcing column does not affect the sliding of the material box. The arrangement of the diverter solves the problem that the gap between the material boxes cannot receive the filtrate filter cake, and the filtrate filter cake is guided into the material box.

[0011] Optionally, there are two reinforcing columns and they are disposed on both sides of the frame in the width direction, and the diverter is fixed between the two reinforcing columns and the two sides are cantilevered above the two material discharge boxes.

[0014] By adopting the above technical solution, a pulley is arranged on the column, and a pulley is arranged under the discharge box, so that the entire filter press can be conveniently transferred and adjusted in position.

[0015] Optionally, when receiving liquid, the filtrate receiving chamber of the material discharge box partially protrudes out of the outside of the frame and is configured as an external connection portion, and the external connection portion is provided with a drainage pipe.

[0016] By adopting the above technical solution, the material discharge box partially protrudes out of the frame, so that the drain pipe will not interfere with the frame, and the drain pipe can recover the filtrate in time.

[0017] Optionally, the end of the drain pipe is U-shaped and inserted into the filtrate receiving cavity, and the drain pipe is slidably matched with the discharge box.

[0018] By adopting the above technical solution, the drain pipe and the discharge box slide together, so that the drain pipe can be fixed to keep the state of the drain pipe stable, and the discharge box also slides relative to the drain pipe during the sliding process relative to the frame, so that the fixation of the drain pipe will not affect the sliding function of the discharge box.

[0019] Optionally, an automatic driving component is provided on one side of the material discharge box, and the automatic driving component includes a driving cylinder for driving the material discharge box to slide.

[0020] By adopting the above technical solution and automatically driving the components, the state of the material box can be automatically switched to achieve automated operation.

[0021] Optionally, a movable box is provided in the filter cake receiving cavity, the movable box is slidably embedded in the filter cake receiving cavity, and recovery handles are provided on both sides of the movable box.

[0022] By adopting the above technical solution, a movable box is provided in the filter cake receiving chamber, and the filter cake can be conveniently transferred by taking and placing the movable box. A recovery handle is provided on the movable box to facilitate lifting and transferring the movable box.

[0023] To summarize, by setting the cavity inside the feeding box to be composed of a filter cake receiving chamber and a filtrate receiving chamber, when the feeding box receives the filtrate, the receiving box slides to the state where the filtrate receiving chamber is located below the filter element, thereby receiving the filtrate through the filtrate receiving chamber. After the filtrate is received, when the feeding box receives the filter cake, the receiving box slides again to the state where the filter cake receiving chamber is located below the filter element, thereby receiving the filter cake through the filter cake receiving chamber. The filter cake and filtrate are received relatively more independently. Compared with simultaneously setting channels for receiving the filtrate and the filter cake, the filter cake receiving chamber has a larger receiving area, and the filter cake is less likely to scatter.
