Description

Technical Field

[0001] This utility model relates to the field of filter press technology for pharmaceutical intermediates, and more particularly to a filter press device for sticky solids. Background Technology

[0002] Sticky solids refer to raw materials that are viscous after being filtered from water. A filter press is a device that uses high pressure on filter plates to squeeze sticky solids, causing the water in the sticky solids to be squeezed out, and finally the remaining solids are squeezed into blocks. When filtering sticky solids, a filter press is required.

[0003] Current filter press devices use multi-layer filter plates for filtration, and it is necessary to ensure that the gap between two adjacent filter plates is kept within a certain distance. However, large filter press devices are expensive, and when using two filter plates to filter large volumes of sticky solids, it may result in the sticky solids in the middle not being completely filtered. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a filter press device for sticky solids that can overcome or at least partially solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A filter press device for sticky solids includes: a frame, and a cavity formed on the frame; two filter plates symmetrically arranged in the cavity, with a filter chamber between the two filter plates, the filter plates sliding in a sealed manner within the cavity; a first filter cloth fixedly arranged on one side of the filter plates; a first mesh plate fixedly arranged within the filter plates, the first mesh plate being in contact with the first filter cloth; drain outlets symmetrically formed on the filter plates; a discharge mechanism arranged on the lower side of the frame, the discharge mechanism being matched with the filter chamber; baffles symmetrically fixedly connected to both ends of the cavity, and a first cylinder fixedly connected between the baffles and the filter plates; a stirring mechanism arranged within the filter chamber; and a feeding assembly for feeding material into the filter chamber.

[0007] To facilitate the discharge of solids after pressure filtration, the discharge mechanism further includes a sealing plate disposed on the lower side of the frame. The lower side of the frame is provided with a limiting groove that matches the sealing plate. The sealing plate is provided with multiple slots. Multiple second cylinders are disposed between the sealing plate and the frame. The extension and retraction ends of the second cylinders are disposed in the slots.

[0008] Preferably, the stirring mechanism includes a rotating shaft symmetrically arranged in the filter press chamber, a plurality of stirring rods fixedly connected to the rotating shaft, a motor fixedly connected to the top of the frame, and the output end of the motor fixedly connected to the rotating shaft.

[0009] To facilitate the falling off of solids after pressure filtration, multiple stirring rods are further arranged in a spiral shape on the rotating shaft, and the stirring rods are inclined downwards.

[0010] To further increase the filtration area, the sealing plate is provided with a through groove, and a second filter cloth and a second mesh plate are fixedly connected in the through groove.

[0011] To facilitate feeding material into the filter press chamber, the feeding assembly further includes a pump fixedly mounted on the frame, with a feeding pipe at the pump's feeding end and a feeding pipe between the pump's discharge end and the filter press chamber.

[0012] Compared with the prior art, the present invention provides a filter press device for sticky solids, which has the following advantages:

[0013] 1. This sticky solid filter press device uses a pump to extract sticky solid raw materials through a suction pipe, and then transports the sticky solid raw materials into the filter press chamber through a feed pipe. After the transport is completed, the solenoid valve in the feed pipe is closed, and the first cylinder drives the two filter plates to move closer to each other, squeezing the sticky solid raw materials in the filter press chamber. The squeezed water flows through the first filter cloth into the filter plates and finally flows out through the drain outlet. During the filter press process, the motor drives the rotating shaft to rotate, and the rotating shaft drives the stirring rod to stir the sticky solid raw materials in the filter press chamber, causing the sticky solid raw materials that have not been fully filtered to shift. Just before the filter press is about to stop, the motor stops working, and the first cylinder continues to extend and squeeze, thereby effectively improving the filter press effect of the sticky solid raw materials and preventing the water in the middle of the raw materials from not being squeezed out.

[0014] 2. This sticky solid filter press device, by tilting the stirring rod downwards, facilitates the falling of the filtered solids, and the spiral arrangement ensures multi-layer mixing while minimizing the number of stirring rods.

[0015] 3. This sticky solids pressure filter device effectively increases its pressure filtration area by setting a second filter cloth and a second mesh plate on the sealing plate, thereby effectively improving the pressure filtration efficiency and effect of sticky solid raw materials.

[0016] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This invention effectively improves the pressure filtration effect on sticky solid raw materials, prevents the moisture in the middle of the raw materials from being unable to be squeezed out, and effectively improves the pressure filtration efficiency of sticky solid raw materials.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figures 1-3 A filter press device for sticky solids includes: a frame 1, and further includes: a cavity 101 formed on the frame 1; two filter plates 2 symmetrically arranged in the cavity 101, with a filter chamber 102 between the two filter plates 2, the filter plates 2 slidingly and sealingly within the cavity 101; a first filter cloth 203 fixedly arranged on one side of the filter plate 2; a first mesh plate 204 fixedly arranged in the filter plate 2, the first mesh plate 204 being in contact with the first filter cloth 203; drain outlets 205 symmetrically formed on the filter plates 2; a discharge mechanism arranged on the lower side of the frame 1, the discharge mechanism being matched with the filter chamber 102; baffles 201 symmetrically fixedly connected to both ends of the cavity 101, and a first cylinder 202 fixedly connected between the baffles 201 and the filter plates 2; a stirring mechanism arranged in the filter chamber 102; and a feeding assembly for feeding material into the filter chamber 102.

[0023] The stirring mechanism includes a rotating shaft 103 symmetrically arranged in the filter press chamber 102, a plurality of stirring rods 104 fixedly connected to the rotating shaft 103, and a motor 105 fixedly connected to the top of the frame 1, and the output end of the motor 105 is fixedly connected to the rotating shaft 103.

[0024] The feeding assembly includes a pump 106 fixedly mounted on the frame 1. The pump 106 has a feeding pipe 108 at its feeding end and a feeding pipe 107 between its discharge end and the filter press chamber 102.

[0025] A solenoid valve is installed inside the feed pipe 107.

[0026] When filtration is performed on sticky solid raw materials, pump 106 draws the sticky solid raw materials through extraction pipe 108 and then transports them into filter chamber 102 through supply pipe 107. After the transport is completed, the solenoid valve in supply pipe 107 is closed, and the first cylinder 202 drives the two filter plates 2 to move closer to each other, squeezing the sticky solid raw materials in filter chamber 102. The squeezed water flows through the first filter cloth 203 into the filter plates 2 and finally flows out through drain outlet 205. During the filtration process, motor 105 drives the rotating shaft 103 to rotate. The rotating shaft 103 drives the stirring rod 104 to stir the sticky solid raw materials in filter chamber 102, causing the sticky solid raw materials that have not been fully filtered to shift. Just before the filtration is about to stop, motor 105 stops working, and the first cylinder 202 continues to extend and squeeze, thereby effectively improving the filtration effect of sticky solid raw materials and preventing the water in the middle of the raw materials from not being squeezed out.

[0027] Example 2: Refer to Figures 1-3 The sticky solid filter press is basically the same as in Example 1. Further, the discharge mechanism includes a sealing plate 301 set on the lower side of the frame 1. A limiting groove 3 matching the sealing plate 301 is opened on the lower side of the frame 1. Multiple slots 302 are provided on the sealing plate 301. Multiple second cylinders 303 are provided between the sealing plate 301 and the frame 1. The extension and retraction ends of the second cylinders 303 are set in the slots 302.

[0028] After the filtration is completed, the two first cylinders 202 are controlled to retract, causing the two filter plates 2 to move away from each other, thereby separating the filter plates 2 from the filtered solids. Then, the second cylinder 303 drives the sealing plate 301 to move downwards, and then the sealing plate 301 is manually removed. At this time, the motor 105 drives the rotating shaft 103 to rotate, causing the filtered solids to fall off, which makes it easier to remove the filtered solid raw materials and effectively prevents the filtered solids from sticking to one of the filter plates 2 when they fall off.

[0029] Multiple stirring rods 104 are arranged in a spiral shape on the rotating shaft 103, and the stirring rods 104 are inclined downward.

[0030] A through groove 304 is provided on the sealing plate 301, and a second filter cloth 305 and a second mesh plate 306 are fixedly connected in the through groove 304.

[0031] By tilting the stirring rod 104 downwards, it is easier for the solids after pressure filtration to fall off, and the spiral arrangement can ensure multi-layer stirring while setting the minimum number of stirring rods 104.

[0032] By setting a second filter cloth 305 and a second mesh plate 306 on the sealing plate 301, the filtration area is effectively increased, thereby effectively improving the filtration efficiency and filtration effect of sticky solid raw materials.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
