Description

Technical Field

[0001] This utility model relates to the technical field of automotive filter housing cleaning equipment, and in particular to a housing cleaning tank for automotive filter processing. Background Technology

[0002] Automotive filters are filtration devices used to filter impurities from liquids or gases. Their internal filter element, made of a series of foldable filter papers stacked together, is the core component for achieving filtration. Common automotive filters include air filters, cabin air filters, oil filters, and fuel filters. As an important component in the automotive and construction machinery industries, the processing quality of the filter housing directly affects the overall performance of the filter. During the processing of the filter housing, inner wall grinding and polishing is one of the key processes. Its purpose is to eliminate burrs, scratches, and other defects on the inner wall, improving the smoothness and precision of the inner wall surface, thereby ensuring the filter's filtration efficiency and service life. In addition, after the filter housing has completed its external machining, its outer surface needs to be coated to improve its surface condition.

[0003] However, existing filter housing processing equipment is often unable to effectively and thoroughly clean the inner and outer walls, resulting in the easy accumulation of debris and oil stains on the walls, affecting the cleanliness of the housing and the efficiency of subsequent processing. Traditional manual brushing easily creates blind spots, leading to poor cleaning quality and low cleaning speed, which is not conducive to mass production. In addition, existing cleaning structures such as spray booths can only remove impurities from the outer surface of the housing, failing to effectively clean the inner walls. Impurities and oil stains adhering to the inner walls can easily affect the performance of the assembled filter product. Utility Model Content

[0004] The purpose of this invention is to provide a shell cleaning tank for automotive filter processing that can simultaneously clean the inner and outer walls of filter housings in batches, thereby improving cleaning efficiency and quality. This solves the problems of traditional manual brushing methods being inefficient and prone to dead corners, making it impossible to perform high-quality cleaning in batches, and existing spray systems typically only cleaning the outer wall and not the inner wall of the housing, resulting in limited cleaning capabilities and inability to meet comprehensive cleaning needs.

[0009] According to a preferred embodiment, the sleeve of the auxiliary stabilizing frame is slidably fitted onto the insert tube, and its assembly position is limited by locking screws inserted into the sleeve.

[0018] The following is a detailed explanation with reference to the accompanying drawings. Example

[0019] This application provides a shell cleaning tank for automotive filter processing, which includes a tank body 1, a hollow support plate 2, an internal rinsing assembly 3, a liquid supply pipeline 4, an ultrasonic transducer 5, and a support base 6.

[0020] according to Figure 1-3In one specific embodiment, the tank 1 contains a cleaning fluid capable of cleaning debris and oil stains from the surface of the cylindrical shell. A perforated support plate 2, capable of suspending and supporting the cylindrical shell, is installed inside the tank 1. Internal flushing components 3, capable of cleaning the inner wall of the cylindrical shell by inserting into it, are arranged in a circumferential array on the perforated support plate 2. A supply pipeline 4 for the cleaning fluid is connected to the input ends of several internal flushing components 3. Several ultrasonic transducers 5 are arranged at circumferential intervals on the inner wall 11 of the tank 1. A support base 6, capable of raising and supporting the tank 1, is also provided on the bottom surface of the tank 1. The internal rinsing component 3 provided in this application can thoroughly and effectively clean the inner wall of the cylinder shell during continuous rotation. Furthermore, the water vortex generated during its rotation can drive the cylinder shell to rotate in the same direction using water friction, effectively exposing different surfaces of the cylinder shell to the working range of the ultrasonic transducer 5. This allows the cavitation bubbles generated by the ultrasonic transducer 5 to effectively clean the cylindrical surface comprehensively. Thus, the cooperation of these modules enables simultaneous and efficient cleaning of the inner and outer walls of the cylinder shell, ensuring cleaning efficiency and quality, and improving the product performance of the cylinder shell. In addition, this application achieves batch and efficient cleaning by arranging several internal rinsing components 3 on the hollow support plate 2 within the pool body 1, improving cleaning adequacy. The water flow rinsing and the coverage and diffusion of the water vortex enhance the cleaning coverage effect of the inner wall, improving the overall cleaning comprehensiveness.

[0021] Preferably, the pool body 1 includes an inner storage pool wall 11 and an outer raised pool wall 12 forming an annular overflow cavity around the inner storage pool wall 11. More preferably, the lower end of the inner storage pool wall 11 is connected to an inverted conical pool bottom 13, which can collect precipitated impurities and facilitate the discharge of debris and residue. More preferably, a drain pipe 14 is inserted into the center of the bottom surface of the inverted conical pool bottom 13. Specifically, both the drain pipe 14 and the drain branch pipe 16 are equipped with a switch valve that can be manually opened and closed. Preferably, the switch valve of the drain branch pipe 16 remains open during cleaning to achieve continuous discharge of waste liquid overflowing during the cleaning process. Preferably, the switch valve of the drain pipe 14 can be opened when periodic cleaning is required. Preferably, a stepped strip 15 capable of supporting the perforated support plate 2 is also provided on the inner side of the inner storage pool wall 11 by welding or other means to limit the placement height of the perforated support plate 2. Preferably, the connection between the perforated support plate 2 and the stepped strip plate 15 is defined by screws that penetrate the plate and are inserted into it. Preferably, the bottom side of the outer raised pool wall 12 is also provided with a drain branch pipe 16 for discharging waste liquid from the overflow tank. Preferably, the drain pipe 14 and the drain branch pipe 16 are connected to the inlet of existing equipment such as cleaning fluid filtration and recovery equipment through pipe bodies with flanges.

[0022] Preferably, a plurality of perforated mesh holes 21 are arrayed on the plate body of the perforated support plate 2, and a support frame 22 is also provided on the plate body to limit the placement position of the cylinder shell. Preferably, the support frame 22 includes a vertical inclined angle plate 221 that is rotatably arranged around the axis of the inner flushing component 3 and welded to the top surface of the perforated support plate 2, and a bent limiting rod 222 provided at the top of the vertical inclined angle plate 221. The perforated support plate 2 provided in this application can provide a general limiting support structure through the support frame 22, thereby limiting the cylinder shell within a certain range, so that the cylinder shell maintains a certain degree of rotatable mobility. Then, when the flushing liquid sprayed by the inner flushing component 3 at an angle can drive the cylinder shell to rotate through liquid friction traction, so that the inner wall of different areas of the cylinder shell can be effectively flushed by the inner flushing component 3, while also changing the outer wall area facing the ultrasonic transducer 5, so that the entire outer wall can be effectively cleaned under the action of cavitation bubbles generated by the ultrasonic transducer 5, so that the inner and outer walls are cleaned simultaneously, thereby improving the cleaning efficiency.

[0023] Preferably, the internal flushing assembly 3 includes a rotating water jet 31, a rotating connecting kit 32, a cartridge tube 33, an auxiliary stabilizing frame 34, and a rotating pipe joint 35. Preferably, the lower axial end of the rotating water jet 31 is connected to the cartridge tube 33 by welding or other means. Preferably, several rotating connecting kits 32 are detachably embedded in the perforated support plate 2 in a circumferentially spaced manner. More preferably, the cartridge tube 33 is inserted into the rotating connecting kit 32 in a manner that allows relative rotation, so that multiple rotating water jets 31 are rotatably supported above the perforated support plate 2. Preferably, the cartridge tube 33 below the perforated support plate 2 is also detachably fitted with an auxiliary stabilizing frame 34 that can suppress swaying during its rotation. More preferably, the liquid inlet port at the lower axial end of the cartridge tube 33 is connected to the liquid supply line 4 through the rotating pipe joint 35. The rotating water jet 31 provided in this application can rotate using the reaction force of the sprayed cleaning fluid to clean the inner wall of the cylinder shell, thereby enabling the sprayed cleaning fluid to effectively cover the inner wall and improve the cleaning effect. The rotating connecting kit 32, insert tube 33, and auxiliary stabilizing frame 34 provided in this application can work together to make the rotating water jet 31 rotate around its axis with high stability, reducing the sway that may occur during rotation and avoiding collision with the cylinder shell to avoid affecting the surface quality of the cylinder shell. At the same time, the friction between the rotating fluid and the cylinder shell is used to pull the cylinder shell to rotate at a speed lower than the rotation speed of the rotating water jet 31, thereby improving the thoroughness of cleaning the inner and outer walls.

[0024] Preferably, a cylindrical cavity 311 communicating with the cavity of the insert tube 33 is formed within the cylindrical body of the rotating water jet 31. Preferably, a plurality of inclined drainage holes 312 are also arrayed on the side of the rotating water jet 31 at an angle to its tangent, allowing it to rotate around its axis under the reaction force of the sprayed cleaning fluid.

Preferably, a one-way valve is provided inside the insert tube 33 to limit the one-way input of cleaning fluid into the rotating water jet 31 via the supply line 4. The inclined drainage hole 312 in this application forms an acute angle with both the tangent of the cylindrical wall of the rotating water jet 31 and the radius line corresponding to that tangent. This causes the cleaning fluid ejected from the inclined drainage hole 312 to generate a near-tangential thrust on the inner wall of the cylinder, effectively driving the rotating water jet 31 to rotate continuously. Furthermore, this angle design maximizes the reaction torque, improving rotational stability and cleaning uniformity. The curved inclined hole 313 guides a portion of the cleaning fluid to be sprayed along a spiral trajectory, enhancing the coverage and rinsing effect on the top curved surface and further improving the ability to clean without dead angles.

[0025] Preferably, the rotating connection kit 32 includes a lower half-shell 321, an upper half-cover 322, a bearing body 323, and a connecting angle plate 324. Preferably, the upper half-cover 322 is joined to the top of the lower half-shell 321 by welding or other means to form an isolation accommodating chamber and limit the bearing body 323 between the two. Preferably, a through-cavity for accommodating the insert tube 33 is centrally formed in the lower half-shell 321 and the upper half-cover 322, and a gap-filling gasket is embedded on the inner wall surface of the through-cavity of the lower half-shell 321 and the upper half-cover 322 to fill the insertion gap of the insert tube 33, so that the insert tube 33 is effectively separated from the cleaning fluid. Preferably, the outer ring of the bearing body 323 is fixedly connected to the lower half-shell 321 by welding or other means, and the inner ring of the bearing body 323 is fitted onto the insert tube 33 by welding or clamping. Preferably, the outer side of the lower half-shell 321 is also connected in a rotationally symmetrical manner with a plurality of connecting corner plates 324 that can be bolted to the hollow support plate 2 to define the assembly position. This utilizes the connecting corner plates 324, located above the hollow support plate 2 and connected to it via bolts, to define the embedding position of the lower half-shell 321 on the hollow support plate 2. The lower half-shell 321 and upper half-cover 322 provided in this application can cooperate with the insert tube 33 to form an isolation cavity, thereby achieving isolation when the bearing body 323 is installed.

[0026] Preferably, the sleeve 341 of the auxiliary stabilizing frame 34 is slidably fitted onto the insert tube 33, and its assembly position is defined by locking screws 342 inserted into the sleeve 341. Preferably, multiple L-shaped limiting rods 343 arranged circumferentially are connected to the side of the sleeve 341 by welding or other means. Specifically, the locking screws 342 penetrate the sleeve 341 and abut against the surface of the lower half of the casing 321 when manually tightened, to define the relative position of the two. The auxiliary stabilizing frame 34 can help improve the stability of the insert tube 33 when rotating around its axis, avoiding problems such as swaying.

[0027] Preferably, the liquid supply pipeline 4 includes a plurality of branch risers 41 distributed circumferentially through the bottom of the inverted conical pool 13, an annular main pipe 42 connected to the plurality of parallel branch risers 41, and a liquid supply main pipe 43 for supplying cleaning liquid to the annular main pipe 42.

Preferably, the input end of the liquid supply main pipe 43 is connected to the cleaning liquid storage tank, and a pressurizing device such as a pressurizing pump is provided at the connection point between the two. The pressurizing pump can be an LPE628 type pump, whose drive power is preset. When the operator closes it to the 220V power circuit, it pressurizes the cleaning liquid to a pressure of about 30MPa, so that when the pressurized liquid is output from the 0.5-1mm nozzle, the sprayed liquid can have a recoil force of about 10N, so that it can effectively flush the inside of the cylinder shell and form a water vortex. The water vortex can drive the cylinder shell to rotate at a speed lower than that of the rotating water jet 31, so that the surface of different areas of the cylinder shell can face the ultrasonic transducer 5, thereby achieving comprehensive and thorough surface cleaning.

[0028] Preferably, the ultrasonic transducers 5 provided in this application can be connected in series via external wires, and the wires are fixed to the outer surface of the pool body 1 through an external conduit.

The control method of this application is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is only used to protect the mechanical device and its mechanical structural features. Therefore, this utility model will not explain the control method and circuit connection in detail.
