Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum filters and relates to a filter cloth insulation box for a vacuum filter. Background Art

[0002] At present, the rubber belt vacuum filter in the industry is only equipped with a high-pressure cleaning device. When some materials are more viscous, there will be residual materials on the filter cloth. The filter cloth is easy to be blocked after long-term operation, affecting the filtering effect, increasing the vacuum degree, causing the belt, slide and other accessories to wear and reduce the service life. The filter cloth blockage causes the moisture content of the filter cake to increase, and it needs to be replaced frequently, which increases the use cost and the labor replacement cost. At the same time, the replacement downtime also reduces the production efficiency.

[0003] In order to solve the above problems, a vacuum filter cloth insulation box installed on a rubber belt vacuum filter is proposed. Utility Model Content

[0006] An insulation immersion box is arranged at the rear end of the high-pressure cleaning device, and the insulation immersion box is arranged on the rubber belt vacuum filter. Two symmetrically arranged transmission shafts are arranged in the insulation immersion box, and the outer side walls of the two transmission shafts are fixedly connected with redirecting rollers. The two redirecting rollers are used to redirect and lower the filter cloth.

[0007] Furthermore, a pickling agent is provided in the heat-insulating immersion box, and the liquid level of the pickling agent is higher than the height of the redirecting roller.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] like Figure 1-Figure 5 As shown, the technical solution adopted by the utility model is as follows: a vacuum filter cloth insulation box is installed on a rubber belt vacuum filter 1, the rubber belt vacuum filter 1 is provided with a filter cloth 15, and the rubber belt vacuum filter 1 is provided with a high-pressure cleaning device 3 for cleaning the filter cloth 15; the transmission direction along the filter cloth 15 is the positive direction.

[0023] An insulation immersion box 2 is provided at the rear end of the high-pressure cleaning device 3. The insulation immersion box 2 is provided on the rubber belt vacuum filter 1. Two symmetrically arranged transmission shafts 7 are provided in the insulation immersion box 2. The outer side walls of the two transmission shafts 7 are fixedly connected with redirecting rollers 6. The two redirecting rollers 6 are used to redirect and lower the filter cloth 15 so that the filter cloth 15 can be completely immersed in the pickling agent.

[0024] A pickling agent is provided in the insulation immersion box 2, and the liquid level of the pickling agent is higher than the height of the redirecting roller 6. A liquid inlet 5 and a liquid outlet 4 are provided on the insulation immersion box 2, and the liquid inlet 5 and the liquid outlet 4 are used to continuously circulate the pickling agent in the insulation immersion box 2.

[0025] In this embodiment, the pickling agent is used to clean the filter cloth 15, and the pickling agent in the thermal insulation immersion box 2 can be circulated, ensuring the cleaning efficiency of the filter cloth 15, and the pickling agent input into the thermal insulation immersion box 2 is heated, further improving the cleaning efficiency of the filter cloth 15.

[0026] Embodiment 2

[0027] On the basis of the first embodiment, some technical features are added to form the second embodiment.

[0028] A transmission device is provided inside the heat preservation soaking box 2, and the transmission device consists of two transmission wheels and a transmission belt 8. Any transmission wheel is fixedly connected to any transmission shaft 7. The transmission device is a conventional transmission method and will not be described in detail.

[0029] The filter cloth 15 is cleaned by a cleaning mechanism below the conveyor belt 8 .

[0030] The cleaning mechanism includes two transmission gears 10 rotatably connected to the heat-insulating immersion box 2. The two transmission gears 10 are arranged in an up-and-down manner in the vertical direction. A rotating wheel 9 is fixedly connected to the transmission gear 10 located at the top. The rotating wheel 9 rotates through the movement of the transmission belt 8. A rotating disk 11 is provided on the front end surface of the transmission gear 10. A downward frame 12 is fixedly connected to the rotating disk 11. A cleaning rod 13 is slidably connected in the downward frame 12. A reset spring 14 is provided between the cleaning rod 13 and the inner side wall of the downward frame 12. The two cleaning rods 13 are respectively located above and below the filter cloth 15.

[0031] In this embodiment, when the filter cloth 15 is being transmitted, the filter cloth 15 will drive the two redirecting rollers 6 to rotate, and at the same time, the transmission shaft 7 will also rotate. Under the action of the transmission belt 8, the two transmission gears 10 will be driven to rotate in opposite directions. At the same time, the two rotating discs 11 will also perform the same action. Under the movement of the rotating disc 11, the two cleaning rods 13 will be driven to move relative to or away from each other. When the two cleaning rods 13 move relative to each other, the two cleaning rods 13 will contact the upper and lower surfaces of the filter cloth 15. Due to the squeezing of the cleaning rods 13, the return springs 14 will be compressed, and at the same time, the cleaning efficiency of the cleaning rods 13 on both sides of the filter cloth 15 will be increased. Since this method performs scraping action intermittently, multiple cleaning mechanisms can be set under the conveyor belt 8 to clean the filter cloth 15, so as to comprehensively clean the filter cloth 15, thereby improving the practicality of the insulation box.
