Description

Technical Field

[0001] The utility model relates to the technical field of mixer rubber filtration, in particular to a new type of high-temperature resistant rubber mixer rubber precision filter. Background Technique

[0002] Rubber mixer rubber is a basic rubber compound prepared from polyorganosiloxane containing ethylene-based linear high polymer, compounded with reinforcing fillers, extender fillers and additives imparting various properties. The rubber compound obtained by mixing raw rubber or plasticated rubber with compounding agents on a rubber mill is called mixer rubber. Mixer rubber production mixes compounding agents in an uncrosslinked state in bulk, granular and powdered raw rubber, and the rubber compound has fluidity.

[0003] At present, in the process of mixer rubber production, in order to ensure its high quality and that the rubber compound does not contain any impurities, it is necessary to filter the rubber compound. The precision filters used in the prior art bond the filter screen by bonding. The filter screen is not stably fixed. During the filtration process of the rubber compound, the filter screen is easily detached in the filter due to a large extrusion force, which affects the filtration effect of the rubber compound. Moreover, the existing filters do not have good cleaning measures for the impurities on the surface of the filter screen after one filtration of the rubber compound. The blockage of the filter screen by impurities will affect the filtration efficiency of the filter screen. Content of the Utility Model

[0025] Figures 1-5This is an embodiment of the present utility model, a precision filter for a new type of high-temperature resistant rubber mixing gum, including a mounting frame 1, and a first filter screen frame 2 and a second filter screen frame 3 arranged on the mounting frame 1.

Through the provided mounting frame 1, the quick splicing and clamping between the first filter screen frame 2 and the second filter screen frame 3 are realized, and the first filter screen frame 2 and the second filter screen frame 3 are infinitely fitted by the reverse abutment of the first push rod 603 and the second push rod 612 against the first slider 4 and the second slider 5, ensuring the stability and firmness of the filter screen fixation and avoiding the detachment of the filter screen under the pressure during the colloid filtration process.

[0026] In this embodiment, referring to Figure 3 , Figure 4As shown in the figure, a first push rod 603 is arranged inside the installation pipe 601, and a piston 604 is arranged on the first push rod 603. Both the first push rod 603 and the piston 604 are slidably connected to the installation pipe 601. Connection ports 605 are arranged at both ends of the installation pipe 601. An installation rod 606 is arranged inside the first branch pipe 602, and a sliding block 607 is sleeved on the installation rod 606. A first spring 608 is sleeved on the installation rod 606, and both ends of the first spring 608 are fixedly connected to the sliding block 607 and the first branch pipe 602 respectively. A fixing frame 610 is arranged inside the second branch pipe 609, a second spring 611 is sleeved on the fixing frame 610, a second push rod 612 is arranged inside the second branch pipe 609, and the second push rod 612 is slidably connected to the fixing frame 610. Both ends of the second spring 611 are fixedly connected to the second push rod 612 and the second branch pipe 609 respectively. The second slider 5 is fixedly connected to the first push rod 603, and the first slider 4 is fixedly connected to the second push rod 612. The installation pipe 601 is connected to an air pump through the connection ports 605 at both ends of the installation pipe 601. Gas is filled into the installation pipe 601 through the connection port 605 at the right end of the installation pipe 601, and the gas inside the installation pipe 601 is extracted through the connection port 605 at the left end, so that the piston 604 and the first push rod 603 move to the left, pushing the second slider 5 and the second filter screen holder to move to the left. After the piston 604 and the first push rod 603 move to the leftmost limit, gas continues to be filled into the installation pipe 601. The gas enters the first branch pipe 602 and pushes open the sliding block 607. When the piston 604 does not move to the left end, under the action of the first spring 608, the sliding block 607 has been located at the bottom end of the installation rod 606 inside the first branch pipe 602. When the sliding block 607 moves upward, the opening of the second branch pipe 609 is exposed, and the gas enters the second branch pipe 609 and squeezes the second push rod 612, so that the second push rod 612 moves to the right. The second push rod 612 drives the first slider 4 and the first filter screen holder 2 to move to the right, and the first filter screen holder 2 and the second filter screen holder 3 are closely attached to complete the rapid fixation of the multi-layer filter screen.

[0027] In this embodiment, refer to Figure 5As shown, the cleaning mechanism 7 further includes a cleaning brush 705. The cleaning brush 705 is slidably connected to the moving frame 701. A sliding rod 706 is provided in the moving frame 701, and a third spring 707 is sleeved on the sliding rod 706. The cleaning brush 705 is slidably connected to the sliding rod 706. The two ends of the third spring 707 are respectively fixedly connected to the cleaning brush 705 and the moving frame 701. A cam 708 is provided on the moving frame 701, and the cam 708 is rotatably connected to the moving frame 701 through a rotating shaft. The cam 708 is in contact with the cleaning brush 705. Two symmetrically distributed lead screws 702 are provided in the mounting frame 1, and the two lead screws 702 respectively penetrate through both ends of the moving frame 701 and are respectively threadedly connected to the moving frame 701. Synchronous pulleys 703 are sleeved on the two lead screws 702, and a synchronous belt 704 is provided in the mounting frame 1. The synchronous belt 704 is respectively drivingly connected to the two synchronous pulleys 703. Starting the motor drives the lead screws 702 to rotate. Under the action of the synchronous belt 704 and the synchronous pulleys 703, the two lead screws 702 rotate synchronously. Under the limiting action of the mounting frame 1, the moving frame 701 is pushed. At the same time, starting the motor on the moving frame 701 drives the cam 708 to rotate. The cam 708 intermittently pushes the cleaning brush 705. With the cooperation of the third spring 707, the cleaning brush 705 vibrates up and down to complete the cleaning of the impurities attached to the surface of the filter screen.

[0028] When this embodiment works, the mounting pipe 601 is connected to the air pump through the connection ports 605 at both ends of the mounting pipe 601. Gas is filled into the mounting pipe 601 through the connection port 605 at the right end of the mounting pipe 601, and the gas in the mounting pipe 601 is extracted through the connection port 605 at the left end, so that the piston 604 and the first push rod 603 move to the left, pushing the second slider 5 and the second filter screen frame to the left. After the piston 604 and the first push rod 603 move to the left extreme, gas continues to be filled into the mounting pipe 601. The gas enters the first branch pipe 602 and pushes open the sliding block 607. When the piston 604 does not move to the left end, under the action of the first spring 608, the sliding block 607 has always been located at the bottom end of the mounting rod 606 in the first branch pipe 602. When the sliding block 607 moves upward, the opening of the second branch pipe 609 is exposed. The gas enters the second branch pipe 609 and squeezes the second push rod 612, so that the second push rod 612 moves to the right. The second push rod 612 drives the first slider 4 and the first filter screen frame 2 to move to the right. The first filter screen frame 2 and the second filter screen frame 3 are closely attached to complete the rapid fixation of the multi-layer filter screen. After the filter screen completes one filtration, start the motor to drive the lead screw 702 to rotate. Under the action of the synchronous belt 704 and the synchronous pulley 703, the two lead screws 702 rotate synchronously. Under the limiting action of the mounting frame 1, the moving frame 701 is pushed. At the same time, start the motor on the moving frame 701 to drive the cam 708 to rotate. The cam 708 intermittently pushes the cleaning brush 705. With the cooperation of the third spring 707, the cleaning brush 705 vibrates up and down to complete the cleaning of the impurities attached to the surface of the filter screen.
