Description

Technical Field

[0001] This utility model relates to the field of carbon felt production technology, and more specifically, it relates to a pre-processing washing device for thermal insulation carbon felt. Background Technology

[0002] Carbon felt is a common air filtration material, frequently used in air purifiers, automotive engine air filters, and other devices. Over time, viscose-based carbon felt gradually accumulates dust, dirt, and other particulate matter, affecting its filtration efficiency and lifespan. Therefore, regular cleaning and maintenance of viscose-based carbon felt are necessary.

[0003] For example, the adhesive-based carbon felt cleaning device disclosed in authorization announcement number CN222092778U achieves the purpose of drying the carbon felt after cleaning to prevent excessive moisture inside the carbon felt from affecting subsequent use, and collects and filters the wastewater after cleaning. Through the cooperation between the motor, brush roller one, gear one, brush roller two and gear two, it is possible to easily move the carbon felt into the cleaning tank, and at the same time, the brush roller facilitates the preliminary cleaning of large particles of carbon felt.

[0004] Although the above method achieves the goal of cleaning and drying the carbon felt, during use, a lot of particulate matter is generated during the cleaning process. This particulate matter is filtered through the screen, which will eventually cause the screen to become clogged, affecting the filtration effect. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pre-processing washing device for a filter screen with a self-cleaning heat-insulating carbon felt.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A pre-processing washing device for thermal insulation carbon felt includes a washing tank containing a cleaning device and a filter plate. The filter plate has multiple filter holes evenly spaced along its extension direction on its surface. A rotatable cleaning plate is positioned below the filter plate and is rotatably connected to the side wall of the washing tank via a rotating mechanism. The cleaning plate has an array of permeable holes corresponding to the positions of the filter holes.

[0008] A columnar unblocking component is provided between adjacent permeable holes, and the maximum radial dimension of the unblocking component is smaller than the minimum aperture of the filter hole.

[0009] The lower edge of the cleaning plate has a ring of inclined serrations.

[0010] A drive assembly mounting cavity is provided at a corresponding position on the side wall of the cleaning tank. A rotary motor is fixedly installed in the mounting cavity. The output shaft of the rotary motor is connected to a drive gear that meshes with the inclined saw teeth. The rotation plane of the drive gear is parallel to the lower end face of the cleaning plate.

[0011] The present invention is further configured such that: an annular guide rail groove is provided on the inner side wall of the cleaning pool, and a rotary support bearing is embedded in the guide rail groove; the inner ring of the rotary support bearing is detachably connected to the outer edge of the cleaning plate through a magnetic connector.

[0012] The present invention is further configured such that: the unblocking component includes a spring and a contact head, one end of the spring is fixedly connected to the lower end face of the cleaning plate, and the other end is connected to the bottom of the contact head, and the spring causes the contact head to protrude from the upper surface of the cleaning plate in its natural state.

[0013] The present invention is further configured such that: the top surface of the contact head is a tapered arc surface structure, and the radius of curvature of the arc surface structure gradually increases from the top to the edge.

[0014] The present invention is further configured such that: the upper surface of the cleaning plate is circumferentially distributed with flexible cleaning brushes, and the working surface of the flexible cleaning brushes maintains contact with the lower surface of the filter plate.

[0015] Compared with the shortcomings of the prior art, the beneficial effects of this utility model are as follows:

[0016] By using a rotating cleaning plate with permeable holes in conjunction with a filter plate, the cleaning plate is driven by a rotating motor and the meshing of gears and saw teeth to rotate. This allows the unclogging component to automatically clean impurities from the filter holes during rotation. Combined with the cleaning brush located above the cleaning plate, this provides double cleaning protection. Meanwhile, the spring-loaded unclogging component located below the filter plate generates reciprocating pressure during rotation, effectively preventing fiber accumulation and blockage. The inclined saw teeth structure and the planar meshing of the gears ensure transmission stability. The magnetically connected bearing structure facilitates disassembly and maintenance while ensuring precise positioning of the rotating components. The overall structure significantly improves the cleaning efficiency of carbon felt and extends the service life of the filter components through multiple synergistic effects.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Working principle: When the rotary motor 7 starts, the gear at the output end of the rotary motor 7 meshes with the inclined sawtooth 6 on the lower end face of the cleaning plate 4 and drives the cleaning plate 4 to rotate. At this time, the water permeable holes on the cleaning plate 4 and the filter holes 3 of the filter plate 2 form a relative displacement, so that the unblocking parts 5 between adjacent water permeable holes repeatedly insert into the filter holes 3 to clean impurities during the rotation. At the same time, the cleaning brush above the cleaning plate 4 continuously scrapes the residue on the surface of the filter plate 2. The spring-type unblocking parts 5 generate elastic expansion and contraction under the action of rotational centrifugal force to enhance the unblocking effect. The magnetically connected bearing structure keeps the cleaning plate 4 on a stable trajectory during rotation. The water flow in the cleaning tank 1 forms a circulation channel through the water permeable holes and the filter holes 3, ultimately realizing the automatic cleaning and anti-clogging function of the pores of the filter plate 2.

[0023] like Figures 1 to 2 As shown,

[0024] The system includes a cleaning tank 1, which contains a cleaning device and a filter plate 2. The filter plate 2 has multiple filter holes 3 evenly spaced along its extension direction. A rotatable cleaning plate 4 is provided below the filter plate 2. The inner wall of the cleaning tank 1 is provided with an annular guide rail groove, in which a rotary support bearing 9 is embedded. The inner ring of the rotary support bearing 9 is detachably connected to the outer edge of the cleaning plate 4 through a magnetic connector. The filter plate 2 is cleaned by rotating the cleaning plate 4, thus preventing the filter holes 3 from becoming clogged.

[0025] The cleaning plate 4 has an array of water-permeable holes at the position corresponding to the filter hole 3. The upper surface of the cleaning plate 4 is circumferentially distributed with flexible cleaning brushes. The working surface of the flexible cleaning brushes is in contact with the lower surface of the filter plate 2, and the surface of the filter plate 2 is cleaned by the flexible cleaning brushes.

[0026] A columnar unblocking component 5 is provided between adjacent permeable holes. The maximum radial dimension of the unblocking component 5 is smaller than the minimum aperture of the filter hole 3, which facilitates the unblocking component 5 to extend into the filter hole 3 to clean the filter plate 2.

[0027] The unblocking component 5 includes a spring 10 and a contact head 11. One end of the spring 10 is fixedly connected to the lower end face of the cleaning plate 4, and the other end is connected to the bottom of the contact head 11. In its natural state, the spring 10 causes the contact head 11 to protrude from the upper surface of the cleaning plate 4. The unblocking component 5 between adjacent water-permeable holes repeatedly inserts into the filter hole 3 to clean impurities during rotation.

[0028] The top surface of the contact head 11 has a tapered arc structure, and the radius of curvature of the arc structure gradually increases from the top to the edge, which facilitates the insertion of the contact head 11 into the filter hole 3.

[0029] The lower edge of the cleaning plate 4 is provided with annularly distributed inclined sawtooth 6. A drive component mounting cavity is provided at a corresponding position on the side wall of the cleaning tank 1. A rotary motor 7 is fixedly installed in the mounting cavity. The output shaft of the rotary motor 7 is connected to a drive gear 8 that meshes with the inclined sawtooth 6. The rotation plane of the drive gear 8 is parallel to the lower end face of the cleaning plate 4. The gear at the output end of the rotary motor 7 meshes with the inclined sawtooth 6 on the lower end face of the cleaning plate 4 and drives the cleaning plate 4 to rotate.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
