Description

Technical Field

[0001] The utility model relates to the technical field of rubber product production, in particular to a coarse silicon rubber filtering device. Background Art

[0002] Crude silicone rubber generally refers to a type of silicone rubber material, which has high hardness and wear resistance. It is usually used to manufacture rubber products such as seals, gaskets, vibration absorbers, etc. For the manufacture of crude silicone rubber products, it is usually necessary to ensure the quality and purity of the raw materials. Some particulate impurities will be doped during the preparation of silicone rubber, so it is necessary to filter the crude silicone rubber particles. Existing filtering devices generally only have a single filtering method and cannot achieve an ideal filtering effect. Although mesh filtering can exclude small particle impurities, it is impossible to quickly screen out impurities of the same size, and the existing device cannot immediately process the screened impurities. Often, after the device has been running for a period of time, the machine needs to be stopped to process the accumulated impurities, which greatly affects the filtering efficiency of the device. Therefore, the present invention proposes a crude silicone rubber filtering device to solve the problems mentioned in the above background technology. Utility Model Content

As the push seat 2 is pushed forward, the baffle 3 on the front side of the push seat 2 rises and fits the lower filter screen 7, pushing the rubber particles back and forth, accelerating the rapid screening of the input granular materials;

[0023] Furthermore, referring to Figure 3 , 4 After a period of time, the baffle 3 between the slider seats 6 on both sides is lifted up, so that the filtered rubber particles flow to the lower channel 103, and finally flow into the lower water selection chamber 104. A Z-shaped screen plate 12 connected to the filter box 1 is provided above the water selection chamber 104. Because the density of unqualified particles and rubber particles of different qualities is different from that of normal rubber particles, roughly the same size of particles will be suspended on the surface of the water selection chamber 104. The Z-shaped screen plate 12 is located between the channel 103 and the water selection chamber 104. A number of water filter ports are evenly opened on both sides of the Z-shaped screen plate 12. By controlling the rotation of the Z-shaped screen plate 12, the unqualified particles suspended on the water surface can be swept out of the box;

[0024] Furthermore, referring to Figure 1, a non-complete gear 10 located on the outside of the filter box 1 is fixed on one side of the Z-shaped screen plate 12, a meshing gear 2 9 is arranged on the upper side of the non-complete gear 10, a gear 1 8 is fixed on the front side of the gear 2 9, and another gear 1 8 meshing with it is arranged on the upper side of the gear 1 8, the gears 1 8 and the gear 2 9 on both sides are transferred to the outside of the filter box 1, and a lever 5 is fixed on the inner side of the other gear 1 8, a torsion spring is arranged at the transfer point between the lever 5 and the filter box 1, and the upper end of the lever 5 corresponds to the slider seat 6 on one side, when the electric push rod 4 pushes the push seat 2 to slide back and forth, the slider seats 6 on both sides of the baffle 3 also move together, and when the slider seat 6 on one side moves forward, it pushes the corresponding lever 5, and the lever 5 drives the front gear 1 8 to rotate, and through the meshing other gear 1 8, the gear 2 9 is driven, and the rotation angle of the gear 29 just drives the non-complete gear 10 on the lower side to rotate one circle, that is, the connected Z-shaped screen plate 12 performs a round of impurity removal on the water surface in the water selection chamber 104;

[0025] Furthermore, when the slider seat 6 moves back, the lever 5 rotates under the action of the torsion spring, and at this time, the transmission gear 2 9 does not transmit with the incomplete gear 10 below. The two meshing gears 1 8 are provided to keep the Z-shaped screen plate 12 and the lever 5 at the same steering angle so as to remove impurities from the water surface of the water selection chamber 104, and the gear 2 9 and the incomplete gear 10 with different numbers of teeth are used to maintain the intermittent impurity removal of the Z-shaped passage.

[0026] Furthermore, referring to Figure 3 A water level control valve 13 is installed in the water selection chamber 104. After a period of screening, more and more particles enter the water selection chamber 104, and the water level in the chamber increases accordingly. The water level in the water selection chamber 104 can be maintained by the water level control valve 13. A water outlet mesh port 14 is provided at the lower part of one side of the water selection chamber 104, and water can be discharged through the water outlet mesh port 14.
