Technical Field

[0001] This utility model belongs to the field of industrial container cleaning technology, specifically relating to a hopper cleaning cover that can clean without dead angles. Background Technology

[0002] In automated production processes in industries such as pharmaceuticals and food, containers such as hoppers require frequent online cleaning. Therefore, the cleanliness and hygiene of hoppers are of paramount importance.

[0003] Currently, existing hopper covers with cleaning functions typically only have nozzles inside the cover that face the hopper body for cleaning the inner wall of the hopper. However, the sealing area where the hopper cover contacts the hopper opening (such as the groove where the sealing ring is located and the flange mating surface) is a cleaning dead zone due to its hidden location. This area is prone to material residue and bacterial growth, becoming a source of cross-contamination. Relying solely on manual disassembly and cleaning of this area is time-consuming and labor-intensive, and does not align with the trend towards highly automated production. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and provide a water-proof hopper cleaning cover that can effectively clean traditional blind spots or sealed areas, achieving all-round cleaning without dead angles.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a hopper cleaning cover with no dead angles, comprising an annular cleaning pipe, a self-cleaning branch pipe, and a cleaning cover body for covering the hopper opening. The annular cleaning pipe is fixedly disposed on the cleaning cover body, and at least one nozzle is disposed on the annular cleaning pipe. The nozzle is configured to spray cleaning medium toward the inner wall of the hopper. One end of the self-cleaning branch pipe is in fluid communication with the annular cleaning pipe, and at least one self-cleaning nozzle is disposed on the self-cleaning branch pipe. The self-cleaning nozzle is configured to spray cleaning medium toward the sealed area between the cleaning cover body and the hopper opening.

[0006] In some embodiments, the self-cleaning branch pipe is arranged perpendicularly to the plane of the cleaning cover body, so that the spray axis of the self-cleaning nozzle is directly aligned with the sealing area.

[0007] In some embodiments, there are multiple self-cleaning branch pipes, which are evenly distributed circumferentially, and each self-cleaning branch pipe is provided with a self-cleaning nozzle.

[0008] In some embodiments, the annular cleaning pipe and the self-cleaning branch pipe are integrally formed or connected by a detachable connector.

[0009] In some embodiments, an elastic sealing ring is fixedly provided inside the cleaning cover body, and the self-cleaning nozzle is configured to spray cleaning medium toward the contact area between the elastic sealing ring and the hopper opening.

[0010] In some embodiments, the inner side of the cleaning cover body is provided with a snap-fit ​​groove with an inverted U-shaped cross-section, and the elastic sealing ring is fitted into the snap-fit ​​groove, thus forming a snap-fit ​​engagement between the elastic sealing ring and the cleaning cover body.

[0011] In some embodiments, the resilient sealing ring has a free sealing portion extending outside the snap-fit ​​groove, the sealing force of which is configured to act primarily on the sidewall of the hopper opening.

[0012] In some embodiments, the free sealing portion has an arcuate sealing surface that conforms to the sidewall of the hopper opening.

[0013] In some embodiments, the cleaning cover body is provided with a limiting buckle plate that fastens to the side wall of the hopper opening.

[0014] The beneficial effects of this utility model are as follows: By adding self-cleaning branch pipes and self-cleaning nozzles, the hopper cleaning cover can perform targeted and active cleaning of blind spots or sealed areas, achieving cleaning of blind spots and thorough cleaning without dead angles. By integrating the main cleaning (ring-shaped cleaning pipe) and blind spot cleaning (self-cleaning branch pipe) into one unit, the hopper cleaning cover has a full-coverage cleaning capability, achieving the purpose of thorough cleaning without dead angles.

Detailed Implementation

[0017] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0019] The directional and positional terms used in this utility model, such as up, down, front, back, left, right, inside, outside, top, bottom, side, etc., are only for reference to the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments: like Figure 1-3 As shown, a hopper cleaning cover with no dead angles includes an annular cleaning pipe 2, a self-cleaning branch pipe 3, and a cleaning cover body 1 for covering the opening of the hopper 4. The annular cleaning pipe 2 is fixedly installed on the cleaning cover body 1, and at least one nozzle 21 is provided on the annular cleaning pipe 2. The nozzle 21 is configured to spray cleaning medium toward the inner wall of the hopper 4. One end of the self-cleaning branch pipe 3 is in fluid communication with the annular cleaning pipe 2, and at least one self-cleaning nozzle 5 is provided on the self-cleaning branch pipe 3. The self-cleaning nozzle 5 is configured to spray cleaning medium toward the sealed area between the cleaning cover body 1 and the opening of the hopper 4.

[0021] like Figure 1 and 2As shown, the self-cleaning branch pipe 3 is vertically arranged relative to the plane of the cleaning cover body 1, so that the spray axis of the self-cleaning nozzle 5 is directly aligned with the sealing area. The vertical arrangement of the self-cleaning branch pipe allows the cleaning medium to directly impact the sealing area with the shortest path and minimal pressure loss, ensuring that the jet stream has the maximum impact force and can effectively remove stubborn stains. The vertical layout is the simplest and most stable structural form, saving internal space, avoiding interference with the internal components of the hopper, and improving the overall reliability of the equipment. There are multiple self-cleaning branch pipes 3, which are evenly distributed circumferentially, and each self-cleaning branch pipe 3 is equipped with a self-cleaning nozzle 5. Through multiple evenly distributed self-cleaning branch pipes, 360° coverage is ensured, achieving all-round and synchronous cleaning of the annular sealing area and eliminating any possible cleaning dead corners. The simultaneous operation of multiple self-cleaning nozzles significantly reduces the time required to thoroughly clean the entire sealing area, effectively improving equipment utilization. The annular cleaning pipe 2 and the self-cleaning branch pipe 3 are integrally formed or connected by detachable connectors. The annular cleaning pipe and the self-cleaning branch pipe adopt an integrally formed structural design, eliminating leakage and improving structural strength. The annular cleaning pipe and the self-cleaning branch pipe are connected by a detachable connector, which allows for quick replacement or cleaning of clogged self-cleaning branch pipes and self-cleaning nozzles, greatly reducing maintenance difficulty, time and cost, and improving the equipment's flexibility and maintainability.

[0022] like Figure 2As shown, an elastic sealing ring 6 is fixedly installed inside the cleaning cover body 1, and the self-cleaning nozzle 5 is configured to spray cleaning medium toward the contact area between the elastic sealing ring 6 and the opening of the hopper 4. An inverted U-shaped snap-fit ​​groove 11 is provided inside the cleaning cover body 1. The elastic sealing ring 6 is fitted into the snap-fit ​​groove 11, forming a snap-fit ​​engagement between the elastic sealing ring 6 and the cleaning cover body 1. The inverted U-shaped snap-fit ​​groove structure design inside the cleaning cover body ensures that the elastic sealing ring is easily pressed in and fixed, yet difficult to detach on its own, resulting in a strong connection, excellent fatigue and impact resistance, and easy replacement. The elastic sealing ring 6 has a free sealing portion 61 extending outside the snap-fit ​​groove 11. The sealing force of the free sealing portion 61 is configured to primarily act on the side wall 41 of the opening of the hopper 4. The free sealing portion 61 has an arc-shaped sealing surface 62 that adheres to the side wall 41 of the opening of the hopper 4. By applying the main sealing force of the elastic sealing ring to the side wall of the hopper switch, rather than the end face, this sealing method is more efficient and less labor-intensive, achieving a better sealing effect with a smaller axial clamping force. The elastic sealing ring contacts the side wall of the hopper opening through its arc-shaped sealing surface, resulting in low sealing start pressure and better adaptability to minor deformations of the hopper opening, thus enhancing sealing adaptability and reliability. The arc surface also facilitates smooth flow of cleaning fluid and provides a self-cleaning effect. The cleaning cover body 1 is equipped with a limiting buckle 7 that engages with the side wall 41 of the hopper opening 4. The limiting buckle serves a dual purpose: pre-positioning and preventing detachment. When the cleaning cover is placed on the hopper, it guides the cleaning cover into position quickly and accurately, preventing displacement before locking.

[0023] This hopper cleaning cover, by adding self-cleaning branch pipes and self-cleaning nozzles, can perform targeted and active cleaning of blind spots or sealed areas, achieving thorough cleaning without dead angles. By integrating the main cleaning (ring-shaped cleaning pipe) and blind spot cleaning (self-cleaning branch pipe) into one unit, the hopper cleaning cover has a full-coverage cleaning capability, achieving the goal of thorough cleaning without dead angles.

[0024] The above description is only one embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model; the scope of protection of the present utility model is defined by the claims in the claims, and all equivalent changes and modifications made in accordance with the utility model are within the scope of protection of the present utility model patent.
