Description

Technical Field

[0001] The utility model belongs to the technical field of chemical synthetic rubber post-processing equipment, and in particular relates to an anti-blocking device for a filtrate guide port of a first-level screw sleeve of an expander. Background Art

[0002] After the polymerization and coagulation process, the rubber material contains a large amount of water outside the rubber and water inside the rubber. The rubber particle water pump pumps the water-containing rubber material to the post-processing workshop. After vibration dehydration or static screening dehydration, a large amount of water outside the rubber is first removed, and then a part of the water outside the rubber and water inside the rubber are squeezed out by the extrusion dehydrator. Finally, the expansion dryer uses the expansion principle to remove part of the water outside the rubber and water inside the rubber, and then enters the subsequent supplementary drying link. When the rubber enters the first-level screw sleeve of the expander and is squeezed, a large amount of water will enter the inlet shower system.

[0003] In addition to a large amount of water, the filtrate entering the shower system also contains a small amount of material fragments. After the equipment has been running for a long time, the material fragments will be deposited in the shower port and its pipeline system, causing the shower port drainage system to be blocked, resulting in sewage flowing across the work site. Long-term operation of the equipment will result in poor drainage, difficulty in feeding materials, and even return of materials. The company has to shut down the machine, cut and weld, and clean the shower pipeline system, causing the production system to be unable to operate normally. Utility Model Content

[0027] Example 3

[0028] The invention discloses an anti-clogging device for the filtrate drain port of the first-stage screw sleeve of an expander, comprising a rubber expander 1, one end of the rubber expander 1 is connected to a filter unit, the side of the filter unit away from the rubber expander 1 is connected to a reducer 2, the reducer 2 is connected to a screw 3, the rod body of the screw 3 passes through the filter unit and the rubber expander 1, the top of the filter unit is connected to a feeding mechanism, the side of the filter unit away from the feeding mechanism is connected to a drain pipe 4, the pipe body of the drain pipe 4 is connected to a pressure reduction system, the side wall of the filter unit is connected to a flushing mechanism, and one end of the flushing mechanism is arranged in the pressure reduction system.

[0029] The material discharging mechanism comprises a material discharging hopper 5, and a small-mouth end of the material discharging hopper 5 is connected to the filtering unit.

[0030] The filtration unit includes a filtrate box 6, the top of the filtrate box 6 is connected to the lower hopper 5, the opposite side walls of the filtrate box 6 are respectively connected to the rubber expander 1 and the reducer 2, the screw 3 passes through the filtrate box 6, the bottom of the filtrate box 6 is connected to a filter plate 7, the bottom of the filtrate box 6 is connected to a liquid storage tank 8, the bottom of the liquid storage tank 8 is connected to the shower pipe 4, and the flushing mechanism passes through the side wall of the liquid storage tank 8.

[0032] The flushing mechanism includes a hot water branch pipe 11, which passes through the side wall of the liquid storage tank 8. The hot water branch pipe 11 is set to an "L"-shaped structure.

[0033] The pressure reduction system includes a mixing tube 12, which is connected to the shower pipe 4. The diameter of the mixing tube 12 is larger than that of the shower pipe 4. The mixing tube 12 is coaxially connected to the shower pipe 4.

[0036] Hot water with a certain pressure is input into the mixing tube 12 from the hot water branch pipe 11. Due to the large pressure drop, the hot water flow rate at the outlet of the hot water branch pipe 11 is relatively high, and the pressure in the mixing tube 12 is slightly lower than the pressure at the shower port. A large amount of clear water in the slurry of the water-containing rubber entering from the lower hopper 5 is filtered out, and the rubber material is driven by the screw 3 to perform axial movement in the rubber expander 1. During the movement, the temperature and pressure of the rubber increase, and it is squeezed out at the template 14 and rapidly expands and explodes, volatilizing the moisture and harmful gases wrapped in the rubber. It is initially filtered from the filtrate box 6 through the filter plate 7, and some powder mixed filtrate still enters the liquid storage tank 8, and then quickly enters the mixing tube 12 under the action of the suction force in the mixing tube 12, mixes with the hot water in the hot water branch pipe 11, and enters the subsequent drainage system from the subsequent shower pipe 4 at a high flow rate.

[0037] The utility model discloses an anti-clogging device for the filtrate drain port of the first-stage screw sleeve of the expander. Through filtering on the filter plate, part of the material fragments in the filtered mixed liquid are sucked into the mixing chamber and are impacted by high-pressure and high-speed hot water and discharged under the action of high-speed water flow. This completely solves the problem of frequent blockage of the inlet drain port of the first-stage screw sleeve of the expander, which not only ensures the long-term stable and efficient operation of the post-processing equipment, reduces the maintenance labor intensity, but also improves the working environment.
