[0003] After searching, the patent document with announcement number CN219050470U discloses a filtering device for the production of rubber additives, including a filter box and a sealing plate. The sealing plate is rotatably connected to the top of the filter box. The outer wall of the filter box is provided with a mounting assembly. The outer wall of the filter box is installed with a filter assembly. The filter assembly consists of a pressurizing unit and a filter unit. The device can slide the filter bin, thereby facilitating the installation and removal of the filter bin, and facilitating the removal of the filtered rubber additives.

[0004] However, the above-mentioned filtering device still has the following technical problems when in use:

[0005] 1. When filtering rubber additives, the filter chamber cannot be automatically locked and fixed. Workers need to manually install and fix it with bolts, which is inconvenient.

[0006] 2. When fixing the filter chamber, it is impossible to fix the filter chamber from multiple positions, and the fixing effect of the filter chamber is poor, resulting in poor sealing effect inside the device, which reduces the filtering effect of the rubber additive. Utility Model Content

The utility model proposes a filtering device for rubber additive production, which enables a wedge-shaped clamping block to automatically pop out after the filter frame is installed to limit and fix the filter frame. At the same time, the fixing frame is fixed in multiple positions by means of clamping columns and clamping grooves, thereby improving the sealing effect.

[0008] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0009] A filtering device for producing rubber chemicals, comprising:

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0028] Referring to Figures 1-5 , a filtering device for rubber auxiliaries production includes:

[0029] The device body 1, a placement cavity 11 is opened on one side wall of the device body 1, and a filter frame 12 is arranged in the placement cavity 11;

[0030] Among them, an air delivery pipe 13 is arranged above the device body 1. The lower part of the air delivery pipe 13 is communicated with the placement cavity 11, and the upper part is connected to an air pump, so that the placement cavity 11 can be inflated through the air pump to increase the air pressure in the placement cavity 11, and the rubber auxiliaries are extruded by high pressure, thereby completing the filtering work of the rubber auxiliaries. This is the prior art and will not be elaborated here.

[0031] The guiding assembly 2, the guiding assembly 2 includes two racks 21, the two racks 21 are fixedly connected to the two side walls of the placement cavity 11, both side walls of the filter box 12 are rotatably connected with rotating rods 22, and interference fits of gears 23 are arranged on each rotating rod 22, and the two gears 23 are respectively meshed with the two racks 21;

[0032] The fixing assembly 3, the fixing assembly 3 includes two mounting blocks 31 fixedly connected to the side wall of the device body 1, wedge-shaped clamping blocks 32 are slidably connected in the two mounting blocks 31, one sides of the two wedge-shaped clamping blocks 32 close to each other extend outside the two mounting blocks 31, and the two wedge-shaped clamping blocks 32 are respectively elastically connected to the inside of the mounting blocks 31 through two springs 33.

[0033] Among them, a baffle 121 is fixedly connected to one side of the filter box 12 away from the gear 23, and a sealing film is arranged on one side wall of the baffle 121 close to the device body 1, so that when the baffle 121 is closely attached to the side wall of the device body 1, the inside of the placement cavity 11 can be sealed to ensure that high-pressure gas will not overflow.

[0034] It is worth mentioning that when installing the filter box 12, only need to place the two gears 23 on the filter box 12 above the two racks 21, and then push the filter box 12 into the placement cavity 11. At this time, the two gears 23 rotate. During the process of the filter box 12 entering the placement cavity 11, it can squeeze the two wedge-shaped clamping blocks 32 into the inside of the two mounting blocks 31. When the baffle 121 is completely attached to the outer wall of the device body 1, the two wedge-shaped clamping blocks 32 automatically pop out under the elastic force of the springs 33 and abut against one side wall of the baffle 121 away from the device body 1, automatically completing the limit fixation of the baffle 121 and the filter box 12, without manually installing the filter box 12 through bolts, and the operation is convenient.

[0035] The locking assembly 4, the locking assembly 4 includes clamping grooves 41 opened on the two rotating rods 22, clamping columns 42 are slidably connected to the outer walls on both sides of the device body 1, and the two clamping columns 42 both extend into the placement cavity 11 and cooperate with the two clamping grooves 41.

[0036] Among them, fixing rods 321 are fixedly connected to the two wedge-shaped clamping blocks 32, and the two fixing rods 321 are respectively fixedly connected to the two clamping columns 42, so that when the two wedge-shaped clamping blocks 32 pop out, the two clamping columns 42 are driven by the two fixing rods 321 to move into the placement cavity 11, and further into the clamping grooves 41 opened on the rotating rods 22.

[0037] Among them, sliding grooves 322 are opened on the two mounting blocks 31, and the two fixing rods 321 respectively extend outside the mounting blocks 31 through the two sliding grooves 322. The two sliding grooves 322 can limit the fixing rods 321, so that the movement of the fixing rods 321 and the clamping columns 42 will not deviate.

[0038] It should be noted that after the filter box 12 completely enters the placement cavity 11, the two wedge-shaped clamping blocks 32 pop out, and drive the clamping column 42 to move into the placement cavity 11 through the fixing rod 321, and further enter the card slots 41 opened on the rotating rod 22, so that the rotating rod 22 cannot rotate. Through the engagement of the gear 23 and the rack 21, the filter box 12 cannot move, and the filter box 12 can be further fixed from the two rotating rods 22, improving the fixing effect of the filter box 12, preventing high-pressure gas from flowing out of the device body 1, and ensuring the filtering effect of high-pressure gas on rubber additives.

[0039] The functional principle of the present utility model can be elaborated through the following operation methods:

[0040] When in use, the filter box 12 is pushed into the placement cavity 11, so that the baffle 121 is closely attached to the outer wall of the device body 1. At this time, the two wedge-shaped clamping blocks 32 automatically pop out and abut and fix the baffle 121, thus automatically completing the fixation of the filter box 12. At the same time, the two wedge-shaped clamping blocks 32 drive the two clamping columns 42 to move towards the inside of the placement cavity 11 through the two fixing rods 321, and further move into the card slots 41 opened on the rotating rod 22, and further lock and fix the filter box 12 from the two rotating rods 22, improving the fixing effect of the filter box 12, preventing high-pressure gas from flowing out of the device body 1, and ensuring the filtering effect of high-pressure gas on rubber additives;

[0041] After the installation of the filter box 12 is completed, the air pump is used to supply air into the placement cavity 11, and the rubber additives are filtered by high-pressure gas. After the filtering is completed, the two wedge-shaped clamping blocks 32 are pushed into the two mounting blocks 31. At this time, the two clamping columns 42 are pulled out of the two card slots 41, and the filter box 12 can be pulled out.

[0042] The above is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
