Description

Technical Field

[0001] This utility model relates to the field of hydraulic flipping technology for filter covers, and in particular to a hydraulic 90-degree flipping opening mechanism for filter covers. Background Technology

[0002] Filters are widely used in many fields such as environmental protection, chemical industry, pharmaceuticals, and food.4 After a period of use, filters require maintenance of internal components such as filter elements, including cleaning and replacement. Traditional methods of opening filter covers require lifting equipment such as cranes, which is cumbersome, limited by space and equipment, inefficient, and may damage filter components or cause safety accidents due to improper operation.

[0003] Currently, existing hydraulic 90-degree flip-opening mechanisms for filter covers are unsuitable for certain special factory environments where electric drive devices cannot be used due to safety or other special reasons. Most filter cover opening methods on the market are either electric or manual. Electric opening methods are unusable in these factories without electricity, while manual opening methods are not only laborious and inefficient, but also difficult to smoothly open and close heavy covers, failing to meet the actual operational needs of factories. Therefore, there is an urgent need for a mechanism that can conveniently, safely, and efficiently open and close filter covers in environments without electricity. Summary of the Invention

[0004] The purpose of this utility model is to solve the problem that in some special factory environments, where electric drive equipment cannot be used due to safety or other special reasons, most filter cover opening methods on the market are electric or ordinary manual. Electric opening methods cannot be used in these factories without electricity, while ordinary manual opening methods are not only laborious and inefficient, but also difficult to achieve smooth opening and closing of heavy covers, which cannot meet the actual operation needs of the factory. Therefore, a hydraulic 90-degree flip opening mechanism for filter covers is proposed.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a filter cover hydraulic 90-degree flip-opening mechanism, comprising a body, a flip-connector installed on the top side of the body, a top cover installed on the other end of the flip-connector, a hydraulic pump installed on the outer wall of the body, a manual hydraulic controller installed on the top of the hydraulic pump, a hydraulic cylinder installed on the side of the body, the output end of the hydraulic cylinder connected to the flip-connector, the hydraulic pump fixed to the hydraulic cylinder through a hydraulic pipeline, a water outlet pipe fixed at the bottom of the body, multiple filter bodies installed inside the body, a valve installed on the top of the top cover, a release opening mechanism installed on the other end of the valve, and a safety lock installed inside the flip-connector.

[0006] Preferably, the outer walls of the top cover and the body at opposite ends are both fixed with housing flanges, and the two housing flanges are fixed together by bolts and nuts.

[0007] Preferably, a lifting plate is fixed on the outer wall of the machine body, and one end of the bolt and nut is installed on the top of the lifting plate.

[0008] Preferably, four legs are evenly distributed on the outer wall of the machine body, and the bottom of each of the four legs is fixed with a pad. The bottom of the filter body is provided with a discharge port, and the side is provided with a feed port.

[0009] Preferably, a water inlet pipe is fixed inside the machine body, and one end of the water inlet pipe passes through the machine body and is fixed with a VC nozzle.

[0010] Preferably, a first pressure gauge interface is installed on the outer wall of the water outlet pipe, a second pressure gauge interface is installed on the top of the top cover, and a positioning plate is fixed on the top of the body.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, an operator uses a manual hydraulic controller to drive a hydraulic pump. Repeated pressing forces hydraulic oil through the hydraulic lines into the hydraulic cylinder, pushing the piston rod out and causing the top cover to rotate. The rotation is achieved through the engagement of the rotating connector. When the top cover needs to be closed, the manual hydraulic controller is operated in reverse, causing the piston rod to retract and the top cover to slowly fall back into a sealed fit with the machine body. This device is manually hydraulically driven, requiring no electricity, making it particularly suitable for factory environments where electricity is unavailable. This expands the filter's applicability. Compared to ordinary manual opening methods, manual hydraulic drive provides greater power, easily opening and closing heavier top covers, reducing operator workload. The 90-degree rotating opening design fully exposes the filter's interior, facilitating quick inspection and replacement of filter elements, improving work efficiency. The simple structure, few main components, low failure rate, and convenient maintenance effectively reduce operating costs. Attached Figure Description

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, as Figure 1-4 As shown, this utility model provides a hydraulic 90-degree flip-opening mechanism for a filter cover, including a body 4, a flip-connector 7 installed on the top side of the body 4, a top cover 1 installed on the other end of the flip-connector 7, a hydraulic pump 22 installed on the outer wall of the body 4, a manual hydraulic controller 24 installed on the top of the hydraulic pump 22, a hydraulic cylinder 10 installed on the side of the body 4, the output end of the hydraulic cylinder 10 connected to the flip-connector 7, the hydraulic pump 22 fixed to the hydraulic cylinder 10 through a hydraulic pipeline 23, a water outlet pipe 26 fixed at the bottom of the body 4, multiple filter bodies 17 installed inside the body 4, a valve 21 installed on the top of the top cover 1, a release opening mechanism 20 installed on the other end of the valve 21, and a safety lock 25 installed inside the flip-connector 7.

[0021] The overall effect of Embodiment 1 is as follows: the operator operates the manual hydraulic controller 24, which drives the hydraulic pump 22. By repeatedly pressing the pump, hydraulic oil enters the hydraulic cylinder 10 through the hydraulic line 23, pushing the piston rod out and causing the top cover 1 to rotate. With the cooperation of the rotating connector 7, the top cover 1 is rotated 90 degrees. When it is necessary to close the top cover 1, the manual hydraulic controller 24 is operated in reverse, causing the piston rod of the hydraulic cylinder 10 to retract. The top cover 1 slowly falls back and seals against the machine body 4. The operation of the safety lock 25 can limit the rotating connector 7 to a certain extent, preventing accidental movement. By releasing the opening mechanism 20, the gas inside the machine body 4 can be discharged through the valve 21.

[0022] Example 2, as Figure 1-4 As shown, the outer walls of the top cover 1 and the body 4 at opposite ends are both fixed with housing flanges 2. The two housing flanges 2 are fixed together by bolts and nuts 3. The outer wall of the body 4 is fixed with a lifting plate 18. One end of the bolt and nut 3 is installed on the top of the lifting plate 18. Four support legs 8 are evenly distributed on the outer wall of the body 4. The bottom of the four support legs 8 is fixed with a gasket 9. The bottom of the filter body 17 is provided with a discharge port and the side is provided with a feed port. A water inlet pipe 6 is fixed inside the body 4. One end of the water inlet pipe 6 passes through the body 4 and is fixed with a VC nozzle 14. The outer wall of the water outlet pipe 26 is installed with a first pressure gauge interface 15. The top of the top cover 1 is installed with a second pressure gauge interface 16. The top of the body 4 is fixed with a positioning plate 19.

[0023] The overall effect of embodiment 2 is that, through the setting of bolts and nuts 3 and housing flange 2, auxiliary fastening treatment can be performed between top cover 1 and body 4. Through the setting of first pressure gauge interface 15 and second pressure gauge interface 16, it is convenient to install pressure gauges and convenient to monitor the pressure inside body 4.

[0024] Working principle: When using this device, the body 4 is securely installed in the designated position. The top cover 1 and the body 4 are connected using the flip connector 7, ensuring a tight connection and smooth rotation of the top cover 1. The hydraulic pump 22, hydraulic cylinder 10, and hydraulic pipeline 23 are connected in sequence, ensuring that the hydraulic pipeline 23 is sealed without leakage. The operator operates the manual hydraulic controller 24 to drive the hydraulic pump 22. By repeatedly pressing, hydraulic oil enters the hydraulic cylinder 10 through the hydraulic pipeline 23, pushing the piston rod to extend and causing the top cover 1 to rotate. With the cooperation of the flip connector 7, it rotates 90 degrees. When the top cover 1 needs to be closed, the manual hydraulic controller 24 is operated in reverse, causing the piston rod of the hydraulic cylinder 10 to retract, and the top cover 1 slowly falls back to seal against the body 4. This device is manually hydraulically driven and requires no electricity, making it particularly suitable for factory environments where electricity is unavailable. This expands the application range of the filter. Compared to ordinary manual opening methods, manual hydraulic drive can provide greater power, easily opening and closing heavier top covers, reducing the labor intensity of operators. The 90-degree flip opening design can fully expose the inside of the filter, facilitating quick maintenance and replacement of filter elements, improving work efficiency. The structure is simple, with few main components, a low failure rate, and convenient maintenance, effectively reducing operating costs.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
