Description

Technical Field

[0001] This utility model relates to the field of sewage valve technology, and in particular to a sewage valve that is anti-clogging, durable, and easy to clean. Background Technology

[0002] In daily life and production, a large amount of sewage is discharged, which often needs to be stored and treated in sewage tanks. Sewage valves are needed when discharging sewage. Sewage contains many pollutants, which can be divided into three categories according to their corrosive properties: physical, chemical and biological. All of them are highly corrosive to sewage equipment, including sewage valves.

[0003] In existing technologies, filter screens are used to block impurities in wastewater. When a large amount of impurities adhere to the filter screen and affect water flow, the filter screen needs to be disassembled and cleaned, which affects work efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the prior art: the prior art uses a filter screen to block impurities in sewage. When a lot of impurities adhere to the filter screen and affect the water flow, the filter screen needs to be disassembled and cleaned, which will affect the work efficiency. Therefore, this utility model proposes a sewage valve that is anti-clogging, durable and easy to clean.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A clog-resistant, durable, and easy-to-clean sewage valve includes a cylinder and a fixed rod, wherein the fixed rod is fixedly connected inside the cylinder and a sleeve is fixedly connected to the fixed rod;

[0007] The sleeve is equipped with a cleaning component, which includes fan blades, a rotating shaft, scrapers, a collection chamber, and a limiting rod. Multiple fan blades are arranged in a ring array at one end of the rotating shaft. The ends of the fan blades away from the rotating shaft are slidably connected to the inner side wall of the sleeve. Two scrapers are respectively fixedly connected to both sides of the rotating shaft. A limiting rod is slidably connected to the side wall of the cylinder. The end of the limiting rod away from the cylinder is slidably connected to the sleeve. The collection chamber is fixedly connected to the lower end of the cylinder. A thrust spring is provided between one end of the limiting rod and the cylinder. A sealing plate is provided at the lower end of the collection chamber.

[0008] Preferably, the cleaning component further includes a filter screen, which is fixedly connected inside the cylinder, and the scraper is slidably connected to one side of the filter screen.

[0009] Preferably, a partition is slidably connected to one side wall of the collecting cavity, and a second lead screw is rotatably connected to the side wall of the collecting cavity, the second lead screw being threadedly connected to the partition.

[0010] Preferably, a square frame is fixedly connected to each end of the filter screen, and a tapping block is slidably connected to the square frame. The tapping block is arranged in an isosceles trapezoidal shape.

[0011] Preferably, a support rod is provided on one side of the striking block, and a spring is fixedly connected between the support rod and the square frame.

[0012] Preferably, the upper end of the cylinder is fixedly connected to an installation cavity, the installation cavity is provided with a baffle, and a first lead screw is threadedly connected to the installation cavity, the lower end of the first lead screw being threadedly connected to the upper end of the baffle.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When sewage flows through the sleeve, it can drive the fan blades and drive the shaft to rotate. When the shaft rotates, it can drive the scraper to move in a circular motion on the filter screen, pushing the impurities attached to the filter screen to the upper side of the collection chamber. Under the action of gravity, they flow into the collection chamber, thus achieving the function of collecting impurities. When the sealing plate at the lower end of the collection chamber is opened, the impurities under the partition are discharged, thus achieving the function of cleaning impurities even during normal operation.

[0015] 2. As the scraper rotates continuously, it intermittently pushes the striking block to strike the filter screen. After the filter screen is vibrated, the impurities attached to the filter screen will be shaken out of the filter holes, making it easier for the scraper to scrape the impurities to the upper side of the collection chamber for collection.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0023] Reference Figures 1-4 A clog-resistant, durable, and easy-to-clean sewage valve includes a cylinder 1 and a fixed rod 6. The fixed rod 6 is fixedly connected inside the cylinder 1, and a sleeve 5 is fixedly connected to the fixed rod 6. The upper end of the cylinder 1 is fixedly connected to an installation cavity 3, and a baffle is provided inside the installation cavity 3. The lower end of the first screw 4 is threadedly connected to the upper end of the baffle. The rotation of the first screw 4 can drive the baffle to move up and down within the installation cavity 3 and the cylinder 1. When the baffle moves into the cylinder 1, it can block the sewage flowing through the cylinder 1.

[0024] A cleaning component is installed on the sleeve 5, which includes fan blades 11, a rotating shaft 12, scrapers 13, a collection chamber 8, and a limiting rod 2. Multiple fan blades 11 are arranged in a ring array at one end of the rotating shaft 12. The ends of the fan blades 11 away from the rotating shaft 12 are slidably connected to the inner wall of the sleeve 5. The end of the rotating shaft 12 away from the fan blades 11 is rotatably connected to the filter screen 7, so that the filter screen 7 and the fan blades 11 provide support for the rotating shaft 12. Two scrapers 13 are fixedly connected to both sides of the rotating shaft 12. A limiting rod 2 is slidably connected to the side wall of the cylinder 1. The end of the limiting rod 2 away from the cylinder 1 is slidably connected to the sleeve 5, and the end of the limiting rod 2 passes through the sleeve 5 and is positioned between two adjacent fan blades 11. The collection chamber 8 is fixedly connected to the lower end of the cylinder 1, and one end of the limiting rod 2 is connected to the cylinder 1. A thrust spring is provided between the two fan blades 11. When cleaning is required, the thrust spring can push the limiting rod 2, so that the limiting rod 2 is between two adjacent fan blades 11, and the fan blades 11 play a limiting role. A sealing plate is provided at the lower end of the collection chamber 8. The sealing plate can be opened. After the sealing plate is opened, the impurities on the bottom wall of the collection chamber 8 can be discharged. At the same time, the sealing plate can also seal the collection chamber 8. The cleaning component also includes a filter screen 7, which is fixedly connected inside the cylinder 1. The scraper 13 is slidably connected to one side of the filter screen 7. A square frame 16 is fixedly connected to both ends of the filter screen 7. A knocking block 15 is slidably connected to the square frame 16. The knocking block 15 is arranged in an isosceles trapezoidal shape. A support rod is provided on one side of the knocking block 15. A spring 14 is fixedly connected between the support rod and the square frame 16.

[0025] A partition 10 is slidably connected to one side wall of the collecting chamber 8, and a second lead screw 9 is rotatably connected to the side wall of the collecting chamber 8. The second lead screw 9 is threadedly connected to the partition 10. The partition 10 is used to seal the collecting chamber 8. When the partition 10 seals the collecting chamber 8, the sealing plate is opened, and the impurities at the bottom of the collecting chamber 8 are discharged without affecting the normal operation of the valve.

[0026] In this invention, when sewage passes through the cylinder 1, the filter screen 7 can block impurities in the sewage. When the sewage flow slows down after passing through the cylinder 1, it indicates that there are many impurities on the filter screen 7. At this time, the limiting rod 2 is pulled and the thrust spring is stretched. As the limiting rod 2 moves away from the sleeve 5, it no longer has a limiting effect on the fan blade 11 inside the sleeve 5. At this time, when the sewage flows through the sleeve 5, it can push the fan blade 11 and drive the rotating shaft 12 to rotate. When the rotating shaft 12 rotates, it can drive the scraper 13 to move in a circular motion on the filter screen 7, and push the impurities attached to the filter screen 7 to the upper side of the collection chamber 8. Under the action of gravity, they flow into the collection chamber 8, realizing the collection of impurities. Then, the second lead screw 9 is rotated and the partition 10 is moved. The partition 10 can isolate the collection chamber 8. Then, the sealing plate at the lower end of the collection chamber 8 is opened. At this time, the impurities on the lower side of the partition 10 are discharged, realizing the cleaning of impurities even during normal operation.

[0027] As the two scrapers 13 move in a circular motion, they can push the striking block 15 to the right and strike the filter screen 7, while compressing the second spring 14. As the scraper 13 continues to move away from the striking block 15, the striking block 15 will reset under the elastic force of the second spring 14. Therefore, as the scraper 13 rotates continuously, it can intermittently push the striking block 15 to strike the filter screen 7. After the filter screen 7 is vibrated, the impurities attached to the filter screen 7 will be shaken out of the filter holes, making it easier for the scraper 13 to scrape the impurities to the upper side of the collection chamber 8 for collection.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
