Description

Technical Field

[0001] This utility model relates to the field of mechanical seals, and in particular to a high-temperature cleaning controller with a sealing structure. Background Technology

[0002] In existing technologies, high-temperature cleaning controllers are intelligent devices used to precisely regulate the operation of high-temperature cleaning equipment, and are widely used in industrial manufacturing, food processing, medical equipment, semiconductor chips, and other fields. The core function of a high-temperature cleaning controller is to ensure that the cleaning process is efficient, safe, and stable in a high-temperature environment by monitoring and controlling parameters such as temperature, pressure, and liquid level in real time. Because it is used in a cleaning environment, the high-temperature cleaning controller must meet sealing requirements.

[0003] The housing of a high-temperature cleaning controller is generally composed of a top cover and a bottom cover that snap together. However, in practical applications, users often have specific requirements regarding the top surface of the top cover, which should not have any fasteners, nor should there be any fasteners along the longer sides of the top cover. This is mainly due to considerations such as aesthetic requirements and space constraints that make disassembly and assembly inconvenient for users.

[0004] Especially for structures where the length is much greater than the width (e.g., the top and bottom covers are rectangular, with the side in the length direction being much larger than the side in the width direction), the welding deformation in the length direction is much greater than that in the width direction, which can easily cause the middle of the length direction to bulge, forming small gaps in the areas where sealing is required.

[0005] Therefore, conventional methods of fastening the top and bottom covers cannot meet the requirement of not using fasteners.

[0006] In view of this, the inventors of this application have designed a high-temperature cleaning controller with a sealed structure in order to overcome the above-mentioned technical problems. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the defect in the prior art where it is difficult to seal between the upper and lower covers when fasteners are not used for sealing, and to provide a high-temperature cleaning controller with a sealing structure.

[0008] The present invention solves the above-mentioned technical problems through the following technical solution:

[0009] A high-temperature cleaning controller with a sealing structure is characterized in that the high-temperature cleaning controller includes a lower cover with an upper opening, an upper cover with a lower opening, a sealing gasket, and at least two connecting parts. The upper end face of the lower cover is provided with an annular protrusion, which surrounds the opening of the lower cover.

[0010] The connectors are respectively installed on at least one set of sides of the lower cover, and the sealing gasket is installed on the lower end face of the upper cover, surrounding the opening of the upper cover;

[0011] The upper cover and the lower cover are fastened together, the sealing gasket abuts against the lower part of the protrusion, and the upper cover is fixed to the connector from the side of the upper cover by fasteners.

The connecting portion extends vertically upward along the upper end surface of the lower cover, and the fitting portion is connected to the connecting portion and is inclined upward and outward.

[0013] According to one embodiment of the present invention, the sealing gasket is annular and is fitted and fixed to the lower end surface of the upper cover.

[0014] According to one embodiment of the present invention, when the upper cover and the lower cover are fastened together, the sealing gasket is pressed tightly against the fitting part.

[0015] According to one embodiment of the present invention, the connector is installed on the side of the upper end surface of the lower cover in the length direction.

[0016] According to one embodiment of the present invention, the connector is mounted around the four sides of the upper end surface of the lower cover.

[0017] According to one embodiment of the present invention, the connectors are installed at intervals on each side of the upper surface of the lower cover.

[0018] According to one embodiment of the present invention, the connector is a connecting plate, the connecting plate is L-shaped, and both ends of the connecting plate are fixed to the upper cover by fasteners.

[0019] According to one embodiment of the present invention, the connector is a hollow connecting tube or a solid connecting tube, and both ends of the connecting tube are fixed to the upper cover by fasteners.

[0020] According to one embodiment of the present invention, the height of the connector is lower than that of the protrusion.

[0043] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Preferred embodiments of the present invention will now be described in detail, examples of which are shown in the drawings. Wherever possible, the same reference numerals will be used in all the drawings to denote the same or similar parts.

[0044] Furthermore, although the terminology used in this invention is selected from commonly known and used terms, some terms mentioned in this specification may have been selected by the applicant in his or her judgment, and their detailed meanings are explained in the relevant sections of the description herein.

[0045] Furthermore, it is required that this utility model be understood not only through the actual terminology used, but also through the meaning implied by each term.

[0046] In the field of high-temperature cleaning controllers, high-temperature water is used at the controller's input and output during high-temperature cleaning of electrode sheaths. Customers are mostly in the chemical industry, using the equipment outdoors and requiring rinsing. This means water enters from all directions, typically requiring an IP65 protection rating. Simultaneously, for ease of maintenance, minimal screw tightening is required to improve efficiency. However, insufficient screw tightening inevitably leads to substandard controller sealing.

[0047] Based on this, the present invention discloses a high-temperature cleaning controller with a sealing structure. For example... Figures 1 to 4 As shown, the high-temperature cleaning controller includes a lower cover 10, an upper cover 20, a sealing gasket 30, and at least two connecting parts 40. The upper part of the lower cover 10 has an opening, making it open. The lower part of the upper cover 20 has an opening, making it open. An annular protrusion 50 is provided on the upper surface of the lower cover 10, surrounding the opening of the lower cover 10.

[0048] Connectors 40 are respectively installed on at least one set of sides of the lower cover 10, and sealing gaskets 30 are installed on the lower end face of the upper cover 20, surrounding the opening of the upper cover 20. When the high-temperature cleaning controller is installed, the upper cover 20 and the lower cover 10 are fastened together, forming a cavity for storing parts.

[0049] At this time, the sealing gasket 30 and the protrusion 50 press against each other to seal the cavity and prevent external liquid from flowing into the cavity. Meanwhile, the upper cover 20 is fixed to the connector 40 from the side by fasteners (e.g., fastening screws).

[0050] In this embodiment, the protrusion 50 can preferably be configured to include a connecting portion 51 and a fitting portion 52. The connecting portion 51 extends vertically upward along the upper end surface of the lower cover 10, and the fitting portion 52 is connected to the upper part of the connecting portion 51 and is inclined upward and outward to form a shape similar to a "funnel". For example, the fitting portion 52 can be configured as a flanged structure, which can compress the sealing gasket 30 and improve the sealing performance.

[0051] Meanwhile, the sealing gasket 30 is preferably annular and is fixedly attached to the lower end surface of the upper cover 20. The sealing gasket 30 is preferably a flat, thin sheet structure.

[0052] With the above-mentioned structure in place, when the upper cover 20 and the lower cover 10 are fastened together, the sealing gasket 30 abuts against the lower part of the protrusion 50, and the sealing gasket 30 is pressed tightly against the fitting part 52, which can increase the fit between the sealing gasket 30 and the protrusion 50. By pressing from top to bottom, a surface contact seal is formed, thereby achieving a more optimized sealing effect.

[0053] More preferably, if the lower cover 10 and the upper cover 20 are rectangular, then the length of their side edges in the longitudinal direction is greater than the length of their side edges in the width direction. Because the deformation in the longitudinal direction is greater than in the width direction when the upper and lower covers are pressed together, it is easy to cause a bulge in the middle of the longitudinal direction, thus forming a small gap.

[0054] Therefore, the connector 40 is preferably installed on the side of the lower cover 10 along its length, for example, by fastening screws. The two connectors 40 are symmetrically fixed to the side of the upper end face of the lower cover 10 along its length, thereby strengthening the lower cover 10 along its length and reducing deformation under stress.

[0055] If the lower cover 10 and the upper cover 20 are square, circular, elliptical, or other polygonal shapes, the connector 40 can be mounted around the upper surface of the lower cover 10. Alternatively, the connector 40 can be mounted at intervals on the upper surface of the lower cover 10. These structures can all achieve the present application and are all within the scope of protection of this application.

[0056] Furthermore, the structure of the connector 40 can preferably be a connecting plate structure. For example... Figure 4 As shown, the connecting plate is preferably L-shaped, including a base plate 41, a side plate 42, and two end plates 43. The side plate 42 is vertically mounted on one side of the base plate 41, and the end plates 43 are respectively mounted between the base plate 41 and the side plate 42 at both ends of the connecting plate. The thickness of the plate material can preferably be a thin stainless steel plate of about 1.5 mm. Of course, this is just an example and is not intended to limit it. Plate materials of other thicknesses or other materials can be used in this application and are within the protection scope of this application.

[0057] The base plate 41, side plate 42, and end plate 43 are preferably connected by welding. The welded areas are sandblasted to achieve a smooth surface, and then ground smooth after welding. All sharp edges and burrs can be deburred to make the connector 40 smooth to the touch.

[0058] When the connector 40 is installed, a first mounting hole 411 is provided on the base plate 41, which is fixed to the lower cover 10 by fasteners (e.g., fastening screws). The upper cover 20 is fastened to the lower cover 10, and the connector 40 is located inside the upper cover 20. The side plate 42 faces the outside of the lower cover 10, which can cover the connection gap between the upper cover 20 and the lower cover 10, preventing external liquids (e.g., water) from flowing in through the connection gap between the upper cover 20 and the lower cover 10, thus playing a blocking role. The side end face of the upper cover 20 overlaps with the end plate 43 of the connector 40, and the end plate 43 of the connector 40 is provided with a second mounting hole 431. The upper cover 20 and the end plate 43 of the connector 40 are fixed by fasteners (e.g., fastening screws 432 and washers 433). The connector 40 can further prevent external liquids (e.g., water) from entering the cavity.

[0059] In addition, the shape and structure of the connector 40 can be changed in other ways. For example, the connector 40 can also be a hollow connector tube or a solid connector tube, and the two ends of the connector tube can be fixed to the top cover 20 by fasteners (e.g., fastening screws).

[0060] Preferably, the height of the connector 40 is lower than that of the protrusion 50, so that the sealing gasket 30 can be pressed against the protrusion 50 with a small force. In addition, there is a gap between the upper end of the connector 40 and the sealing gasket 30, or the upper end of the connector 40 is in contact with the sealing gasket 30, either form is acceptable.

[0061] As mentioned above, the high-temperature cleaning controller with a sealed structure of this application adds two connecting pieces along the length of the lower cover to reduce welding deformation and save costs. This allows for fastening with only two screws on each of the upper and lower surfaces of the upper cover, preventing liquid (such as water) from seeping in, improving sealing performance, and saving time on disassembling and assembling the upper cover.

[0062] According to the above structural description, the working process of the high-temperature cleaning controller with sealing structure of this utility model is as follows: when water flows in from the upper cover 20 and the lower cover 10 in both width directions, it is sealed by fasteners and sealing gaskets 30. When water flows in from the side length direction of the upper cover 20 and the lower cover 10, the connector 40 can effectively prevent water from entering.

[0063] In addition, the gap between the upper cover 20 and the lower cover 10 is very small (0.5-1mm), and there is a sealing gasket 30 on top for sealing. The combined effect of multiple sealing structures can achieve effective sealing.

[0064] In practical applications, the high-temperature cleaning controller with a sealing structure of this utility model has been tested for sealing and can achieve IP65, realizing the sealing of this controller with no bolts on the top surface, no bolts in the length direction, and a length direction that is much larger than the width direction.

[0065] In summary, the high-temperature cleaning controller with a sealing structure of this utility model adopts a non-top-bottom fastening structure, adding a connecting part in the length direction to improve the overall sealing performance. The high-temperature cleaning controller, through the connecting part and sealing gasket, enhances the sealing performance of the non-top-bottom fastening, thereby solving the sealing problem of products that are not top-bottom fastened.
