Description

Technical Field

[0001] The utility model belongs to the technical field of resin production equipment, in particular to a resin impurity filter. Background Art

[0002] The resin liquefies after being exposed to high temperature and is used for product production, product packaging, etc. In actual use, some impurities in the added materials and auxiliary materials cannot be dissolved, and the impurities will directly affect the quality of subsequent products.

[0003] The traditional filtration method uses a filter to filter directly, and the resin flows downward under the influence of gravity. However, the filtration process is slow and takes a long time, which is not suitable for filtering large quantities of resin. At the same time, when the resin is filtered quickly, the contact between the resin and the filter is likely to cause an increase in bubbles. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing resin filtering device has a slow filtering process, a long filtering time, and easily causes an increase in bubbles in the resin during the filtering process.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: a resin impurity filter, including a base, an inclined groove is opened on the upper part of the base, a support leg is installed at the bottom of the base, and also includes a supporting outer cylinder, a throwing-out mechanism and a propulsion mechanism. A supporting plate is provided at the bottom of the supporting outer cylinder, and the supporting outer cylinder is installed on the upper part of the groove through the supporting plate. The throwing-out mechanism is arranged in the supporting outer cylinder and is used for centrifugal filtration of resin. The propulsion mechanism is arranged inside the throwing-out mechanism and is used to propel and press the resin to flow downward.

[0006] Furthermore, the ejection mechanism includes a cross bar, a rotating motor, a connecting shaft and a filter cartridge, the cross bar is arranged in the middle of the upper end surface of the supporting outer cylinder, the rotating motor is arranged on the upper part of the cross bar, one end of the connecting shaft is arranged at the output end of the rotating motor, the other end of the connecting shaft is connected to a connecting plate, one end of the filter cartridge is connected to the bottom of the connecting plate, and the filter cartridge is located at the center of the inner part of the supporting outer cylinder.

[0007] Furthermore, a feed hopper is installed at the edge of the upper end surface of the filter cartridge, and a limiting filter screen is connected to the bottom of the filter cartridge. The outer wall of the limiting filter screen is connected to the inner wall of the supporting outer cylinder. The outer wall of the filter cartridge is provided with strip holes, and the strip holes are arranged in a circular shape with equal intervals, and a filter screen is provided in the strip holes.

[0008] Furthermore, the propulsion mechanism includes a second rotating motor, a transmission shaft and a spiral blade. The second rotating motor is arranged at the center of the bottom wall of the filter cartridge, one end of the transmission shaft is arranged at the output end of the second rotating motor, and the other end of the transmission shaft is rotatably arranged in the middle of the bottom wall of the connecting plate, and the spiral blade is wound around the outer wall of the transmission shaft.

[0009] Furthermore, a filter plate is provided in the groove, and the filter plate is vertically arranged along the downward sliding direction of the groove.

[0010] After adopting the above structure, the beneficial effects of the utility model are as follows: when filtering a large amount of resin quickly, multi-stage filtration is achieved for the resin, and the resin flowing downward is centrifugally thrown out by the throwing-out mechanism, so that the resin is initially filtered through the bar holes and the filter screen. When the resin is thrown out of the filter cartridge and hung on the inner wall of the supporting outer cylinder, the resin flows downward, and flows downward again after secondary filtration by the limiting filter screen; when the resin is inside the filter cartridge, the propulsion mechanism pushes and compresses the resin downward in the filter cartridge, squeezing the resin space and reducing contact with the air, thereby increasing its throwing-out density.

DETAILED DESCRIPTION

[0017] like Figure 1 and Figure 2As shown, a resin impurity filter includes a base 1, an inclined groove 2 is opened on the upper part of the base 1, a support leg 3 is installed at the bottom of the base 1, and also includes a supporting outer cylinder 4, a throwing mechanism 5 and a pushing mechanism 6. A supporting plate 7 is arranged at the bottom of the supporting outer cylinder 4, and the supporting outer cylinder 4 is installed on the upper part of the groove 2 through the supporting plate 7. The throwing mechanism 5 is arranged in the supporting outer cylinder 4 and is used for centrifugal filtration of resin. The pushing mechanism 6 is arranged inside the throwing mechanism 5 and is used to push and press the resin to flow downward.

[0018] like Figure 1-4 As shown, in order to increase the filtration efficiency of the resin and shorten the processing time, the ejection mechanism 5 includes a cross bar 8, a rotating motor 9, a connecting shaft 10 and a filter cartridge 11. The cross bar 8 is arranged at the middle of the upper end surface of the supporting outer cylinder 4, the rotating motor is arranged on the upper part of the cross bar 8, one end of the connecting shaft 10 is arranged at the output end of the rotating motor, the other end of the connecting shaft 10 is connected to a connecting plate 12, one end of the filter cartridge 11 is connected to the bottom of the connecting plate 12, the filter cartridge 11 is located at the inner center of the supporting outer cylinder 4, a feed hopper 13 is installed at the edge of the upper end surface of the filter cartridge 11, the bottom of the filter cartridge 11 is connected to a limited filter screen 14, and the outer side wall of the limited filter screen 14 is connected to the supporting outer cylinder 4. At the junction of the inner walls of the cylinder 4, the outer wall of the filter cylinder 11 is provided with strip holes 15, and the strip holes 15 are arranged in a circular shape with equal intervals. A filter screen 16 is arranged in the strip holes 15. The rotating motor 9 drives the connecting shaft 10, drives the connecting plate 12, the feed hopper 13 and the filter cylinder 11 to rotate synchronously, and centrifugally throws out the resin entering the filter cylinder 11. When the resin passes through the filter screen 16, it is thrown out by the filter cylinder 11 and adheres to the inner wall of the supporting cylinder body. It flows downward under gravity, and is filtered again through the limiting filter screen 14 and falls into the groove 2 on the base 1. At the same time, the limiting filter screen 14 limits the bottom of the filter cylinder 11 to prevent the filter cylinder 11 from shaking when it rotates.

[0019] like Figure 2 and 4 As shown, in order to increase the feeding rate of the resin into the filter cartridge 11, and at the same time compress the resin in the filter cartridge 11 to reduce the contact with the air during the feeding process, the propulsion mechanism 6 includes a rotating motor 17, a transmission shaft 18 and a spiral blade 19. The rotating motor 17 is arranged at the center of the bottom wall of the filter cartridge 11, one end of the transmission shaft 18 is arranged at the output end of the rotating motor 17, and the other end of the transmission shaft 18 is rotatably arranged in the middle of the bottom wall of the connecting plate 12. The spiral blade 19 is arranged around the outer wall of the transmission shaft 18. The rotating motor 17 drives the transmission shaft 18 and the spiral blade 19 to rotate, and pushes the resin inside the filter cartridge 11 downward, so that the resin is compressed tightly, the resin throwing density is improved, and the feeding rate of the resin is increased.

[0020] Among them, a filter plate 20 is provided in the groove 2, and the filter plate 20 is vertically arranged along the downward direction of the groove 2. The filter plate 20 is added in the groove 2 to filter the resin again, thereby improving the impurity filtering effect.

[0021] When in use, the operator heats the resin, pours the heated resin into the filter cartridge 11 through the feed hopper 13, starts the rotary motor 17, and the rotary motor 17 drives the transmission shaft 18 and the spiral blade 19 to rotate, pushing the resin inside the filter cartridge 11 downward, so that the resin is compressed tightly, the resin throwing density is increased, and the resin feeding rate is increased;

[0022] At the same time, the rotating motor 9 is started, and the rotating motor 9 drives the connecting shaft 10 to rotate, driving the connecting plate 12, the feed hopper 13, the filter cartridge 11 and the propulsion mechanism 6 to rotate synchronously, and the resin in the filter cartridge 11 is centrifugally thrown out. When the resin passes through the filter screen 16, it is thrown out by the filter cartridge 11 and adheres to the inner wall of the supporting cylinder body. It flows downward under gravity, and is filtered again by the limiting filter screen 14, and falls into the groove 2 on the base 1. At the same time, the limiting filter screen 14 limits the bottom of the filter cartridge 11 to prevent the filter cartridge 11 from shaking when rotating, thereby increasing the stability of the filter cartridge 11;

[0023] When the resin falls on the groove 2, the resin that has been filtered twice is filtered again by the filter plate 20, thereby achieving multi-stage filtration of the resin and improving the filtering effect of impurities.
