Description

Technical Field

[0001] The utility model relates to the technical field of filter presses, in particular to a pull plate trolley for discharging materials of a filter press. Background Art

[0002] A traditional plate and frame filter press consists of a set of filter chambers formed by alternately arranged filter plates and filter frames. There are through holes at the corners of the filter frames and filter plates. After assembly, a complete channel is formed, through which suspension, washing water can be introduced and filtrate can be discharged. There are handle supports on both sides of the filter frames and filter plates, which are supported on the bearing plate and the filter frames and filter plates are pressed by a pressing device. The filter cloth between the filter frames and filter plates acts as a sealing gasket. The suspension is pressed into the filter chamber by a feeding pump to form filter material on the filter cloth until the filter chamber is filled. The filtrate passes through the filter cloth and flows along the grooves of the filter plates to the corner channels of the plate and frame for centralized discharge. After filtration, washing water can be introduced to wash the filter material. Subsequently, the plate and frame filter press is opened to remove the filter material, the filter cloth is cleaned, the filter frames and filter plates are re-pressed, and the next working cycle begins. Most of the traditional pull plate trolleys for discharging materials of the filter press need to be manually reset after discharging, which is rather troublesome. In view of the above problems, a pull plate trolley for discharging materials of a filter press is proposed.

[0003] The application number is 201610740811.4, which discloses an efficient and uniform discharging plate and frame filter press, including a frame, a filter plate group arranged on the frame, a pressing mechanism for pressing the filter plate group, a rotary discharging mechanism for discharging the filter cake on the filter plate group, and a power device; the filter plate group includes a plurality of filter plates arranged side by side; the rotary discharging mechanism includes a guide rail arranged on the frame and a plurality of spaced pull plate trolleys arranged on the guide rail; the plurality of pull plate trolleys are driven by the power device and move unidirectionally and uniformly along the guide rail; each pull plate trolley pulls one filter plate in the filter plate group during the movement process. The invention utilizes a plurality of pull plate trolleys to each pull one filter plate in the filter plate group during the unidirectional movement process, realizes efficient and uniform discharging of the filter cake, and at the same time, can reduce the discharging space, shorten the length of the plate and frame filter press, reduce the floor area, and avoid the technical problems of too large instantaneous speed and too large instantaneous impact load on the equipment caused by simultaneous discharging of multiple filter cakes.

[0004] However, there are deficiencies. The device utilizes a plurality of pull plate trolleys to each pull one filter plate in the filter plate group during the unidirectional movement process, realizes efficient and uniform discharging of the filter cake, and at the same time, can reduce the discharging space, shorten the length of the plate and frame filter press, reduce the floor area, and avoid the technical problems of too large instantaneous speed and too large instantaneous impact load on the equipment caused by simultaneous discharging of multiple filter cakes. However, most of the pull plate trolleys of the device need to be manually reset after discharging, which is rather troublesome. Content of the Utility Model

[0005] The purpose of the present utility model is to provide a pulling plate trolley for a filter press to discharge materials, so as to solve the technical problems raised in the above-mentioned background technology. That is, the device uses multiple pulling plate trolleys to pull one filter plate in each filter plate group during the unidirectional movement, realizing efficient and uniform discharge of the filter cake. At the same time, it can reduce the discharge space, shorten the length of the plate and frame filter press, reduce the floor area, and avoid the problem that the instantaneous speed is too large when multiple filter cakes are discharged simultaneously, resulting in a large instantaneous impact load on the equipment. However, after the pulling plate trolley of this device discharges materials, it mostly needs to be reset manually, which is rather troublesome.

[0006] To solve the above technical problems, the present utility model is realized through the following technical solutions:

[0015] The utility model has the following beneficial effects:

[0016] (1) The utility model is provided with a drawplate trolley structure. First, the operator moves the body of the drawplate trolley to the right, then the turning plate handle abuts against the second baffle, and then the turning plate handle rotates. At the same time, the turning plate handle is linked with the short hook of the trolley. When the short hook of the trolley rotates, multiple components rotate along with it. Then, when the turning plate handle rotates in place, the trolley hook extends out of the body of the drawplate trolley and enters the state where it can draw the plate. The body of the drawplate trolley starts to move to the left. At the same time, the main body of the coil spring applies a counterclockwise force to the short hook of the trolley to keep the state of the short hook unchanged. Then, the trolley hook reaches the filter plate handle, causing multiple components to rotate along with it. Finally, the body of the drawplate trolley can move to the left.

[0017] (2) The utility model is provided with a drawplate trolley structure. The main body of the coil spring applies a counterclockwise force to the trolley hook to reset the hook. The return hook stop plate abuts against the filter plate handle and rotates back. When it abuts against the limit pin shaft, the body of the drawplate trolley cannot continue to move to the left and starts to return. Then, the trolley hook abuts against the filter plate handle, and the body of the drawplate trolley drives the filter plate to move to the right. The main body of the coil spring applies a counterclockwise force to the return hook stop plate to drive the transition wheel plate to rotate, causing the body of the drawplate trolley to drive the main body of the filter plate to move to the corresponding position. The body of the drawplate trolley moves to the left again. Then, the turning plate handle abuts against the baffle and the turning plate handle rotates. The turning plate handle is linked with the short hook of the trolley to make the short hook of the trolley rotate. The main body of the coil spring applies a counterclockwise force to the trolley hook to retract it into the body of the drawplate trolley. And the main body of the coil spring applies a counterclockwise force to the return hook stop plate to drive the transition wheel plate to rotate. Finally, the body of the drawplate trolley moves to the right. Because the trolley hook has been retracted into the trolley, the body of the drawplate trolley can quickly return to the initial position.
