Abstract
Description
Technical Field
[0001] The utility model relates to a filter plate assembly for a filter press, belonging to the technical field of filter presses. Background Art
[0002] A filter press is a mechanical device that uses a special filter medium to apply a certain pressure to an object to allow liquid to dialyze out. It is a commonly used solid-liquid separation device. It has been applied to chemical production since the early 18th century and is still widely used in industries such as chemical industry, pharmacy, metallurgy, dye, food, brewing, ceramics, and environmental protection. The filter plate has stable performance, convenient operation, safety, and labor saving; the metal pressing cylinder is processed from seamless steel pipes and the plastic-steel filter plate is precision cast, with high temperature and high pressure resistance and durability.
[0003] Chinese Patent Publication (Publication No.: CN 205084469 U) discloses a filter plate assembly for a filter press, including a filter plate body and a square protrusion provided at the edge of the filter plate body. A plurality of protrusions are evenly distributed on the upper surface of the filter plate body. The protrusions are located within the square protrusion. Water guide grooves are formed between the protrusions. A plurality of filter holes are evenly distributed in the water guide grooves. The projection of the protrusion on the filter plate body is kidney-shaped. The axes of the protrusions are parallel to each other between the left and right protrusions, and the axes of the protrusions are on the same straight line with the axes of the upper and lower protrusions. The filter holes are located between the protrusions with parallel axes. The utility model provides a filter plate assembly for a filter press with small resistance, fast flow rate, large filtration area, and high filtration efficiency.
[0004] Filter plates are used in filter presses. The filter plate assembly generally consists of a plate frame, a filter plate, and a filter cloth. The filter plate is generally fixedly installed inside the frame by welding, and the filter cloth is generally sewn on the filter plate. During the use of the existing filter plate assembly, due to long-term use, the surface of the filter cloth will cover a lot of filtered debris. When there is too much filtered debris, it may cause the overall filtration effect of the filter plate to deteriorate. At this time, the entire filter plate assembly needs to be replaced, which will waste a lot of resources and the cost is relatively high.
[0005] Therefore, a filter plate assembly for a filter press is proposed. Summary of the Utility Model
[0006] In view of this, the utility model provides a filter plate assembly for a filter press to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.
[0007] The technical solution of the utility model is realized as follows: A filter plate assembly for a filter press includes a filter plate frame. Filter plate bodies are fixedly installed on both the front and rear sides of the inner cavity of the filter plate frame. Feed holes are opened in the middle of the surfaces of the two filter plate bodies.
[0008] Installation mechanisms are provided on both the left and right sides of the inner cavity of the filter plate frame. The installation mechanisms include bidirectional screws and connecting plates. The two bidirectional screws are both movably connected to the left and right sides of the inner cavity of the filter plate frame. Threaded blocks are threadedly connected to the upper and lower sides of the surfaces of the two bidirectional screws. The four connecting plates are all arranged inside the eight threaded blocks. Installation pads are fixedly installed on the outer sides of the four connecting plates. The outer sides of the installation pads are in contact with the surface of the filter cloth.
[0009] Further preferably, T-shaped plates are fixedly installed inside the four threaded blocks. Movable rods are movably connected to the front and rear sides of the surfaces of the four T-shaped plates. The inner sides of the eight movable rods are movably connected to movable blocks. The eight movable blocks are all movably connected to the outer sides of the four connecting plates.
[0010] Further preferably, limiting grooves are provided on both the left and right sides of the inner cavity of the filter plate frame. The outer sides of the four threaded blocks are all slidably connected to the inner cavities of the two limiting grooves.
[0011] Further preferably, synchronous shafts are fixedly connected to the bottoms of the two bidirectional screws. A synchronous belt is movably connected to the surfaces of the two synchronous shafts.
[0012] Further preferably, a knob is fixedly connected to the left side of the outer sides of the two bidirectional screws. Limiting bolts are threadedly connected to the front and rear sides of the top of the knob. The bottoms of the two limiting bolts are threadedly connected to the inner surface of the filter plate frame.
[0013] Further preferably, rubber pads are adhesively bonded to the outer sides of the surfaces of the eight installation pads, and the material of the rubber pads is rubber.
[0014] Further preferably, slots are provided on the front and rear sides of the top of the filter plate frame. The size of the slots is matched with the size of the filter cloth.
[0015] Further preferably, a cover plate is clamped in the inner cavities of the two slots. The left and right sides of the cover plate are threadedly connected to the top of the filter plate frame.
[0016] Due to the adoption of the above technical solutions in the embodiments of the present invention, it has the following advantages:
[0017] 1. The utility model sets up an installation mechanism. By rotating the knob, as the knob rotates, the bidirectional screw synchronously rotates. When the bidirectional screw at the bottom of the knob rotates, through the mutual cooperation between the synchronous shaft and the synchronous belt, the bidirectional screw on the other side in the inner cavity of the filter plate frame synchronously rotates. As the bidirectional screw rotates, the screw block moves outward. At this time, the T-shaped plate moves synchronously with the screw block, and the movable rod flips. When the movable rod flips, the movable block drives the connecting plate to move inward. At this time, the mounting pad moves inward synchronously due to the movement of the connecting plate, and the fixing of the filter cloth by the mounting pad is released. Subsequently, the filter cloth is removed from the inner cavity of the slot, thus completing the disassembly work of the slot. By disassembling the filter cloth, it is convenient to clean the filter cloth, avoiding the overall filtration effect of the equipment from deteriorating due to more surface pollutants covering the filter cloth after long-term use. At the same time, disassembling and cleaning the filter cloth alone can save the steps of disassembling the whole equipment and is convenient for the operator to use.
[0018] 2. The utility model sets up a T-shaped plate, a movable rod, a movable block and a connecting plate, which can make the T-shaped plate move synchronously when the screw block moves inward or outward, and the movable rod pushes the movable block and the connecting plate to move outward, converting the rotating force into an outward pushing force, thus facilitating the fixing of the filter cloth. By setting the limit groove, the movement of the screw block can be limited to avoid the screw block from shifting during movement, thereby affecting the fixing work of the filter cloth. By setting the synchronous shaft and the synchronous belt, a transmission function can be achieved, enabling the bidirectional screw on the left side to drive the bidirectional screw on the other side to rotate synchronously, so that the filter cloth can be fixed on both the left and right sides synchronously, improving the stability of fixing the filter cloth. By setting the limit bolt, the rotation of the knob can be limited to avoid the knob from rotating and affecting the stability of fixing the filter cloth. By setting the rubber pad, since its material is rubber, it is relatively soft and elastic, which can avoid wearing the filter cloth when fixing the filter cloth, thus preventing the filter cloth from being damaged. By setting the slot, it is convenient to pull out the filter cloth, thus facilitating the work of taking and installing the filter cloth. By setting the cover plate, the inner cavity of the filter plate frame can be sealed, and it is also convenient for taking the filter cloth.

Detailed description of the specific implementation
[0027] In the following, only some exemplary embodiments are briefly described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present utility model. Therefore, the drawings and the description are considered to be exemplary in nature and not restrictive.
[0028] The following will detail the embodiments of the present utility model with reference to the drawings.
[0029] Embodiment 1
[0030] As Figures 1-5 shown, the embodiment of the present utility model provides a filter plate assembly for a filter press, including a filter plate frame 1. Filter plates 4 are fixedly installed on both the front and rear sides of the inner cavity of the filter plate frame 1. Feed holes 3 are opened in the middle of the surfaces of the two filter plates 4;
[0031] Installation mechanisms 2 are provided on both the left and right sides inside the cavity of the filter plate frame 1. The installation mechanism 2 includes a bidirectional screw 201 and a connecting plate 206. The two bidirectional screws 201 are both movably connected to the left and right sides inside the cavity of the filter plate frame 1. Threaded blocks 202 are threadedly connected to the upper and lower sides of the surfaces of the two bidirectional screws 201. Four connecting plates 206 are arranged inside the eight threaded blocks 202. Installation pads 207 are fixedly installed on the outer sides of the four connecting plates 206. The outer sides of the installation pads 207 are in contact with the surface of the filter cloth. T-shaped plates 203 are fixedly installed on the inner sides of the four threaded blocks 202. Movable rods 204 are movably connected to the front and rear sides of the surfaces of the four T-shaped plates 203. The inner sides of the eight movable rods 204 are movably connected to movable blocks 205. The eight movable blocks 205 are all movably connected to the outer sides of the four connecting plates 206. Limiting grooves 210 are provided on both the left and right sides inside the cavity of the filter plate frame 1. The outer sides of the four threaded blocks 202 are all slidably connected to the inner cavities of the two limiting grooves 210. Synchronous shafts 208 are fixedly connected to the bottoms of the two bidirectional screws 201. A synchronous belt 209 is movably connected to the surfaces of the two synchronous shafts 208. Knobs 211 are fixedly connected to the left sides of the outer sides of the two bidirectional screws 201. Limiting bolts 212 are threadedly connected to the front and rear sides of the tops of the knobs 211. The bottoms of the two limiting bolts 212 are threadedly connected to the inner surface of the filter plate frame 1. Rubber pads 213 are adhesively bonded to the outer sides of the surfaces of the eight installation pads 207, and the material of the rubber pads 213 is rubber.
[0032] By setting up the installation mechanism 2, by rotating the knob 211, as the knob 211 rotates, the bidirectional screw 201 rotates synchronously. When the bidirectional screw 201 at the bottom of the knob 211 rotates, through the mutual cooperation between the synchronous shaft 208 and the synchronous belt 209, the bidirectional screw 201 on the other side in the inner cavity of the filter plate frame 1 rotates synchronously. As the bidirectional screw 201 rotates, the screw block 202 moves outward. At this time, the T-shaped plate 203 moves synchronously with the screw block 202, and the movable rod 204 is driven to turn. When the movable rod 204 turns, the movable block 205 drives the connecting plate 206 to move inward. At this time, the mounting pad 207 moves inward synchronously due to the movement of the connecting plate 206, and the fixing of the filter cloth by the mounting pad 207 is released. Subsequently, the filter cloth is removed from the inner cavity of the slot 6, thus completing the disassembly work of the slot 6. By disassembling the filter cloth, it is convenient to clean the filter cloth, avoiding the overall filtration effect of the equipment from deteriorating due to more surface pollutants covering the filter cloth after long-term use. At the same time, disassembling and cleaning the filter cloth alone can save the steps of disassembling the whole equipment, facilitating the operation of the operator. By setting up the T-shaped plate 203, the movable rod 204, the movable block 205 and the connecting plate 206, when the screw block 202 moves inward or outward, the T-shaped plate 203 will move synchronously, and the movable rod 204 will push the movable block 205 and the connecting plate 206 to move outward, converting the rotational force into an outward pushing force, thus facilitating the fixing of the filter cloth. By setting up the limiting groove 210, the movement of the screw block 202 can be limited to avoid the screw block 202 shifting during movement, which will affect the fixing work of the filter cloth. By setting up the synchronous shaft 208 and the synchronous belt 209, a transmission function can be achieved, enabling the bidirectional screw 201 on the left side to drive the bidirectional screw 201 on the other side to rotate synchronously, so that the filter cloth can be fixed synchronously on both the left and right sides, improving the stability of fixing the filter cloth. By setting up the limit bolt 212, the knob 211 can be limited to avoid the knob 211 rotating, which will affect the stability of fixing the filter cloth. By setting up the rubber pad 213, since its material is rubber, it is relatively soft and elastic, which can avoid wearing the filter cloth when fixing the filter cloth, resulting in the situation of filter cloth damage.
[0033] Embodiment 2
[0034] In one embodiment, slots 6 are provided on both the front and rear sides of the top of the filter plate frame 1. The size of the slot 6 matches the size of the filter cloth. A cover plate 5 is clamped in the inner cavities of the two slots 6. The left and right sides of the cover plate 5 are threadedly connected to the top of the filter plate frame 1.
[0035] By setting the slot 6, the filter cloth can be easily pulled out, thereby facilitating the work of taking out and installing the filter cloth. By setting the cover plate 5, the inner cavity of the filter plate frame 1 can be sealed, which also facilitates the work of taking out the filter cloth.
[0036] When the filter cloth is in operation, the filter block 202 is moved outward by the cooperation between the synchronous shaft 208 and the synchronous belt 209. At this time, the T-shaped plate 203 moves synchronously with the screw block 202 and causes the movable rod 204 to flip over. When the movable rod 204 flips over, the movable block 205 drives the connecting plate 206 to move inward. At this time, the mounting pad 207 moves inward synchronously due to the movement of the connecting plate 206, and the mounting pad 207 releases the fixation of the filter cloth, and then the filter cloth is removed from the inner cavity of the slot 6, completing the removal of the filter cloth.
[0037] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
