Description

Technical Field

[0001] The utility model relates to the technical field of resin production, in particular to a plate-frame filter for resin production. Background Art

[0002] Resins are a class of polymer compounds that typically possess the properties of being able to flow after softening or melting and solidify after cooling. Broadly speaking, any polymer compound that can be used as a raw material for plastic products can be called a resin. Resins can be categorized by their source into two main categories: natural resins and synthetic resins. Natural resins primarily originate from secretions of organisms such as plants, insects, and animals, such as rosin and amber. Synthetic resins are produced through chemical synthesis, such as polyethylene, polyvinyl chloride (PVC), polystyrene (PS), polypropylene (PP), and ABS resin.

[0003] In the production of resin, it is necessary to use a plate and frame filter to filter the resin to filter out the large particles and impurities inside it to ensure the purity of the resin. The filter cake inside the general plate and frame filter is not convenient to remove, and the resin easily sticks to the inside of the plate and frame. It is very troublesome to clean after internal blockage. The filter frame where the filter cake is placed needs to be cleaned after use to avoid residual substances causing contamination to the next batch of resin filtration. Utility Model Content

[0005] Through the above technical solution, the threaded rod is rotated by the handle, and the threaded rod rotates to drive the pressing plate to move toward the rear end of the feed frame, and the front end of the feed frame is clamped on the inner wall of the right end of the filter cake. When the pressing plate continues to move, several filter cakes are squeezed together, and the card plate at the far left is clamped on the inner wall of the finished product frame and pressed tightly. Then the resin raw material is transported to the interior of the feed frame through the feed pipe, and pressurized by the booster pump. It is filtered through the filter cake and the filter screen and discharged through the discharge port. Through the placement hole, when the resin raw material is installed, the slider is placed from the placement hole into the slide rail, so that the filter cake slides inside the filter frame, and it is convenient for subsequent replacement and disassembly. Through the card plate, when placing the filter cake, the card plate is clamped on the inner wall of the right end of the filter cake for easy stacking. At the same time, the filter screen is clamped inside the card plate through the card plate, which is convenient for subsequent disassembly and cleaning.

[0006] As a further improvement of the above scheme, the rear end of the filter cake is connected to the right end surface of the finished product frame, the number of the filter cakes is set to be several, and the several filter cakes are evenly distributed inside the filter frame, and the number of the sliders is set to be two, and the two sliders are evenly distributed on the surface symmetrically with the center of the bottom of the card plate.

[0007] Through the above technical solution, by providing multiple groups of filter cakes, the resin can be made cleaner during the filtration process.

[0008] As a further improvement of the above solution, the diameter of the clamping plate is smaller than the diameter of the inner wall of the right end of the filter cake.

[0009] Through the above technical solution, the diameter of the card plate is smaller than the diameter of the inner wall of the right end of the filter cake, which makes it convenient to stack multiple filter cakes.

[0010] As a further improvement of the above solution, the threaded rod passes through the inner wall of the filter frame, the limiting plate is concentric with the pressing plate, and the diameter of the feed frame is smaller than the diameter of the inner wall of the right end of the filter cake.

[0011] As a further improvement of the above solution, a nozzle is fixedly connected to the inner wall of the filter frame, the nozzle input end is fixedly connected to a connecting pipe, the connecting pipe input end is fixedly connected to a water pump, and the water pump input end is fixedly connected to a water inlet pipe.

[0012] Through the above technical solution, a nozzle is set on the inner wall of the filter frame, and water is sprayed into the interior of the filter frame through the nozzle by a water pump to clean the residual resin inside the filter frame, which is convenient for subsequent use and avoids contamination of the raw materials by residual resin particles.

[0013] As a further improvement of the above solution, the number of the nozzles is set to two, and the two nozzles are symmetrically and evenly distributed on the inner wall with respect to the front center of the filter frame.

[0014] As a further improvement of the above solution, the connecting pipe passes through the inner wall of the filter frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The utility model provides a placement hole, and when the resin raw material is installed, the slider is placed into the slide rail from the placement hole, so that the filter cake slides inside the filter frame, and is convenient for subsequent replacement and disassembly. When the filter cake is placed, the card plate is clamped on the inner wall of the right end of the filter cake through the card plate, which is convenient for stacking. At the same time, the filter screen is clamped inside the card plate through the card plate, which is convenient for subsequent disassembly and cleaning.

[0017] The utility model provides a nozzle, which is provided on the inner wall of the filter frame. A water pump is used to spray water into the interior of the filter frame through the nozzle, so as to clean the residual resin inside the filter frame, facilitate subsequent use, and avoid contamination of the raw materials by residual resin particles.
