Description

Technical Field

[0001] This utility model belongs to the field of filter press technology, specifically relating to an automatic plate-pulling chamber filter press. Background Technology

[0002] The automatic plate filter press is an intermittent pressure filtration device, mainly used for solid-liquid separation. It is widely used in suspension treatment in industries such as chemical, petroleum, metallurgy, food, and environmental protection. Its core function is to use mechanical pressure to trap solid particles in the suspension on the surface of the filter cloth to form a filter cake, while the liquid passes through the filter cloth and is discharged, thus achieving efficient separation.

[0003] Chinese patent document CN220478223U discloses an automatic plate-pulling chamber filter press. When the filter cake viscosity is too high and cannot be detached, the support is moved to the gap between the filter plates by a second electric slide rail and an electric slider. Then, the rotating shaft is driven by hydraulic pressure to move down. The gear connected to the rotating shaft can mesh with the tooth groove to trigger rotation, so that the rotating shaft drives the internal roller to rotate. In order to use centrifugal force to throw the brush plate inside the roller outward, which strikes the filter plate at high frequency and shakes off the filter cake.

[0004] However, in the existing technology, the mechanical impact method for removing residual filter cake has technical drawbacks, such as the need for precise control of the distance between the impacting parts and the filter plates, and the efficiency limitation caused by intermittent operation of each plate. Therefore, an automatic plate-pulling chamber filter press is proposed. Utility Model Content

[0032] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0033] like Figures 1-6 As shown, an automatic plate-pulling chamber filter press includes a loading assembly 1 that provides an installation position for the core components of the filter press. The loading assembly 1 is provided with multiple filter components 2 that can form filter chambers to filter slurry. The filter components 2 are provided with an adaptive component 3 that can automatically introduce airflow to quickly remove the filter cake when it discharges the filter cake.

[0034] In this embodiment: the loading assembly 1 includes a frame 101, a split unloading plate 102 is movably installed inside the frame 101, two main beams 103 are fixedly installed above the split unloading plate 102, a slide rail 104 is provided on the side of the main beam 103 away from the other main beam 103, a pull plate trolley 105 is movably installed on the slide rail 104, a thrust plate 106 is fixedly installed on one side of the main beam 103, a hydraulic cylinder 107 is fixedly installed on the side of the frame 101 away from the thrust plate 106, and a pressure plate 108 is fixedly connected to the telescopic end of the hydraulic cylinder 107;

[0035] The frame 101 is rotatably connected to the split unloading plate 102, and the main beam 103 is slidably connected to the clamping plate 108.

[0036] The frame 101 provides mounting positions for components such as the split discharge plate 102 that allows batch discharge of filter cake from the filter press, the main beam 103 that provides support and limits for components such as the thrust plate 106 and the clamping plate 108, the slide rail 104 on which the pull plate trolley 105 is installed, and the hydraulic cylinder 107 that adjusts the position of the clamping plate 108. The opening and closing of the split discharge plate 102 is hydraulically controlled (not shown in the attached figure). The position of the filter frame 201 on the main beam 103 is alternately adjusted by the reciprocating movement of the two pull plate trolleys 105 on the slide rail 104. The structure and working method of the pull plate trolley 105 are mature existing technologies in this field, so they will not be described in detail. The thrust plate 106 and the clamping plate 108, which can contact different filter frames 201 at different positions in the filter press, ensure the sealing and pressure transmission between multiple filter components 2.

[0037] In this embodiment: the filter assembly 2 includes a plurality of filter frames 201 movably installed in the loading assembly 1. A drain press valve 202 is fixedly connected to the front and rear of the filter frame 201. The filter assembly 2 also includes a partition 203 fixedly installed in the filter frame 201. A filter frame 204 is fixedly installed in the center of the partition 203. A filter element 205 is fixedly installed in the filter frame 204.

[0038] The main beam 103 is slidably connected to the filter frame 201. The partition 203 and the filter frame 204 are both split structures. The partition 203 and the filter frame 204 are each composed of two identical structures that are mirror-symmetrical to each other. A through hole is provided at the center of the partition 203, and four through holes are provided at the corners of the partition 203. Each through hole is arranged around the through hole, and the center line of the through hole is equidistant from the adjacent side of the outer contour of the partition 203.

[0039] The filter frame 201, which can form a filter chamber, provides installation positions for components such as the drain press valve 202, the partition 203, the one-way valve 301, and the first insertion rod 305. The partition 203 divides the internal space of the filter frame 201 into two parts. The filter frame 204, which contains the filter element 205, separates the internal space of the filter frame 201 into two parts. This allows the solid components of the slurry to be trapped between the two adjacent partitions 203 in two adjacent filter components 2, while the liquid components, under pressure, enter between the two partitions 203 of the same filter component 2 through the filter element 205 and the filter frame 204. The drain press valve 202 controls the opening and closing of the liquid outflow channel of the filter component 2.

[0040] In this embodiment: the adaptive component 3 includes an air inlet that can be connected to an external air source to supply air to the filter component 2 when the filter cake is discharged, a control component that can synchronously control the liquid discharge and air inlet channel opening and closing of the filter component 2, and an adjustment component that can associate the position of the filter component 2 with the liquid discharge and air inlet channel opening and closing state.

[0041] The intake components include a one-way valve 301 fixedly connected above the filter frame 201, and an intake press valve 302 fixedly connected above the one-way valve 301. The control components include second insert rods 307 fixedly connected to the front and rear sides of the filter frame 201 and the pressure plate 108, respectively. A bent handle 308 is movably connected to the second insert rod 307 connected to the filter frame 201. A lever 309 is fixedly connected to the side of the bent handle 308 away from the filter frame 201. Lifting frames 310 are movably connected to the front and rear of the filter frame 201. A connecting rod 311 is movably connected to the lifting frame 310 in front of 201. A toggle frame 312 is provided between the filter frame 201 and the connecting rod 311. The air intake component also includes a connecting pipe 303 fixedly connected above the air intake pressing valve 302. An air intake pipe 304 is fixedly connected between multiple connecting pipes 303. The adjusting component includes a first insert rod 305 fixedly connected to the front and rear sides of the filter frame 201 and located above the second insert rod 307. A telescopic rod 306 is provided between the first insert rod 305 and the bent handle 308.

[0042] The first insertion rod 305 is rotatably connected to the telescopic rod 306. The telescopic rod 306 and the second insertion rod 307 are both rotatably connected to the bent handle 308. The filter frame 201 and the lever 309 are both slidably connected to the lifting frame 310. The lifting frame 310 is rotatably connected to the connecting rod 311. The filter frame 201 and the connecting rod 311 are both rotatably connected to the lever frame 312. The pressing part of the drain pressing valve 202 faces the lower end of the lifting frame 310, and the pressing part of the air inlet pressing valve 302 faces the rear end of the lever frame 312.

[0043] One-way valve 301 prevents liquid in filter assembly 2 from entering air inlet valve 302. Air inlet valve 302 controls the flow of gas through air inlet pipe 304 and connecting pipe 303 into one-way valve 301. When gas is continuously supplied through air inlet pipe 304 of external gas source, connecting pipe 303 can guide the gas to each air inlet valve 302. The first insert rod 305 and the second insert rod 307 respectively determine the position of the telescopic rod 306 and the end of the bent handle 308 relative to filter frame 201, and make... The telescopic rod 306 and the bend handle 308 can rotate around their respective tail ends. The telescopic rod 306 can be a type with a built-in spring that can push its telescopic end away from the rod body. Based on this, the bend handle 308, which has a limited range of motion, will tend to rotate clockwise under the action of the telescopic rod 306 when it is not subjected to external force. The height change caused by the bend handle 308 is transmitted to the lifting frame 310 through the lever 309, and the height change of the lifting frame 310 is transmitted to the lever 312 through the connecting rod 311.

[0044] Working principle: When this automatic plate-pulling chamber filter press is installed and put into use, when the hydraulic cylinder 107 works and makes each filter component 2 tightly fit between the thrust plate 106 and the clamping plate 108, the slurry can be injected into the filter press from the feed port of the thrust plate 106. After the slurry with a certain pressure enters the thrust plate 106, it will flow through the through hole of the partition 203 to each filter component 2 until it fills the space between adjacent partitions 203 in adjacent filter components 2. Under the action of pressure, the liquid components in the slurry will enter the space between the two partitions 203 in the same filter component 2 through the filter element 205 and the filter frame 204, and then be discharged by the drain pressure valve 202 that does not contact the lifting frame 310.

[0045] After the filter press is completed, the hydraulic cylinder 107 can be used to reset the pressing plate 108 to the initial position. When gas is continuously supplied into the air inlet pipe 304, the two pull plate trolleys 105 alternately pull each filter component 2 to move towards the pressing plate 108, thereby separating each filter component 2 from each other so as to trap the filter cake accumulated between adjacent filter components 2 and drop it downward from the position of the opened split discharge plate 102.

[0046] During the process of the filter assembly 2 moving towards the pressure plate 108, the handle 308 of the second insert rod 307 on the pressure plate 108, which no longer contacts the adjacent filter frame 201, will rotate clockwise under the action of the telescopic rod 306. Since the lever 309 rotating with the handle 308 can drive the lifting frame 310 to move down and close the drain press valve 202, the actuating frame 312, which was originally pressed against the air inlet press valve 302 and kept it in a closed state, will be pulled by the connecting rod 311 moving with the lifting frame 310 and will no longer contact the actuating frame 312. Therefore, the gas supplied to the air inlet pipe 304 will enter the two partitions 203 inside the filter assembly 2 through the connecting pipe 303, air inlet press valve 302, and one-way valve 301. Then, the filter frame 204 and filter element 205 will continuously blow the filter cake remaining on the side away from each other of the two partitions 203, so that the filter cake can fall off quickly and fully.

[0047] As each filter frame 201 moves toward the pressing plate 108 in sequence, the above process will be repeated continuously. The gas supplied into the air inlet pipe 304 will enter the filter assembly 2 that is moving due to the pull plate trolley 105 in sequence, either when the bent handle 308 rotates because it does not contact other second insert rods 307, or when the filter frame 201 moves into place and resets. This ensures the overall dropping effect of the filter cake in this filter press.

[0048] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
