Description

Technical Field

[0001] This utility model relates to the field of rotary valve flushing technology, and more specifically, to an intelligent cleaning structure for the feed channel of a rotary valve. Background Technology

[0002] A rotary valve, also called a rotary valve, unloader, or airlock valve, is a device used for unloading materials. It is mainly used to feed materials into the conveying pipe evenly and continuously, while also serving as a seal and airlock. It generally has a feed channel and a discharge channel. The specific principle is to use a motor to drive the impeller to rotate and transport the material from the upper feed channel to the lower discharge channel. At the same time, the gap between the impeller and the housing is used to achieve a seal and prevent gas leakage.

[0003] However, when conveying materials, the current rotary valve feed channel inevitably causes material residue to adhere to the inner wall of the feed channel, especially for sticky materials. This can affect the material conveying process in the long run and is difficult to clean.

[0004] In response to the above situation, this utility model proposes an intelligent cleaning structure for the rotary valve feed channel. Utility Model Content

The rotary motor is fixedly installed on the surface of the lifting seat, and the output end of the rotary motor is fixedly connected to the second gear. The second gear and the first gear mesh with each other, and the first gear is fixed on the outside of the metal conveying pipe.

[0009] In order to enable the movable seat to move on the support frame, preferably, the surface of the support frame is provided with two sliding grooves, each of which is fixedly provided with a sliding rod, and a slider is slidably installed on the outside of the sliding rod. The slider is fixedly installed on the bottom of the movable seat. A mounting base is fixedly assembled on the top of the support frame and on one side of the movable seat. Two electric push rods are fixedly provided on the surface of the mounting base, and the output ends of the two electric push rods are fixedly connected to the outer wall of the movable seat.

[0010] To enable the lifting and adjusting operation of the lifting seat, preferably, two sets of support blocks are fixedly installed on the outer wall of the support plate, and each set of support blocks consists of two blocks.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] As attached Figure 1-5The intelligent cleaning structure for the feed channel of a rotary valve shown includes a support frame 3 installed at the feed port 2 of the rotary valve body 1, and the support frame 3 is used to support the rotary valve body 1. A movable seat 4 is provided on the surface of the support frame 3 and on one side of the feed port 2. A support plate 5 is fixedly provided on the top of the movable seat 4, and a lifting seat 6 is provided on the surface of the support plate 5.

[0023] Specifically, in this structure, the support frame 3 is fixed at the feed inlet 2 of the rotary valve body 1, which can support the rotary valve body 1 without affecting the normal use of the rotary valve. The movable seat 4 can move on the surface of the support frame 3, which facilitates the movement of the rotary flushing structure to the feed inlet 2 of the rotary valve body 1. The lifting seat 6 can be lifted on the support plate 5, which can extend the rotary flushing structure to the feed inlet 2. Thus, without affecting the normal use of the rotary valve body 1, the rotary flushing structure is used to flush the material adhering to the inner wall of the feed inlet 2.

[0024] The structure of this application will be explained in detail below:

[0025] In this embodiment, as shown in the appendix Figure 1 , 4 As shown in Figure 5, the surface of the lifting seat 6 is provided with a rotary flushing structure, which includes a water tank 7. The water tank 7 is fixedly installed on the surface of the lifting seat 6, and a high-pressure pump 8 is provided on one side of the water tank 7. The input end and output end of the high-pressure pump 8 are respectively provided with a connecting pipe 9 and a metal support pipe 10. One end of the metal support pipe 10 is connected to and rotatably installed with a metal conveying pipe 11. The input end and output end of the high-pressure pump 8 are respectively connected to the connecting pipe 9 and the metal support pipe 10. One end of the connecting pipe 9 is connected to the water tank 7. A sealed bearing is provided at the connection between the metal support pipe 10 and the metal conveying pipe 11, and they are rotatably connected through the sealed bearing. The bottom end of the metal conveying pipe 11 extends to the bottom of the lifting seat 6, and an annular pipe 12 is installed at the bottom of the metal conveying pipe 11. Several branch pipes 13 are connected between the annular pipe 12 and the metal conveying pipe 11, and a high-pressure nozzle 14 is connected to the outer wall of the annular pipe 12 in an annular shape.

[0026] Limiting disks 15 are provided on the outside of the metal conveying pipe 11 and at the top and bottom of the lifting seat 6. The metal conveying pipe 11 is rotatably connected to the lifting seat 6. The limiting disks 15 are fixed on the outside of the metal conveying pipe 11 and rotatably connected to the lifting seat 6. A first gear 16 is provided on the outside of the metal conveying pipe 11 and at the top of the limiting disks 15. A second gear 17 is provided on one side of the first gear 16. A rotary motor 18 is provided at the bottom of the second gear 17. The rotary motor 18 is fixedly installed on the surface of the lifting seat 6, and the output end of the rotary motor 18 is fixedly connected to the second gear 17. The second gear 17 and the first gear 16 mesh with each other, and the first gear 16 is fixed on the outside of the metal conveying pipe 11.

[0027] Specifically, in this structure, when the rotary flushing structure flushes the feed inlet 2 of the rotary valve body 1, firstly, the high-pressure pump 8 transports water from the water tank 7 through the connecting pipe 9 and the metal support pipe 10. The metal support pipe 10 transports the water to the inside of the metal conveying pipe 11, and then through multiple branch pipes 13 into the inside of the annular pipe 12. Finally, the water is sprayed out through several high-pressure nozzles 14, and the water sprayed out by the high-pressure nozzles 14 flushes the material adhering to the inner wall of the feed inlet 2.

[0028] During the flushing process, the second gear 17 is driven to rotate by the rotary motor 18, which in turn drives the first gear 16 to rotate. The first gear 16 then drives the metal conveying pipe 11 to rotate. Since a sealed bearing is provided at the connection between the metal support pipe 10 and the metal conveying pipe 11, and they are rotatably connected through the sealed bearing, the metal conveying pipe 11 can rotate with the metal support pipe 10. Moreover, limit plates 15 are provided on the outside of the metal conveying pipe 11 and at the top and bottom of the lifting seat 6. The metal conveying pipe 11 is rotatably connected with the lifting seat 6, and the limit plates 15 are fixed on the outside of the metal conveying pipe 11 and rotatably connected with the lifting seat 6. Therefore, the rotation between the metal conveying pipe 11 and the lifting seat 6 can drive the limit plates 15 to rotate with the lifting seat 6. The limit plates 15 can prevent the metal conveying pipe 11 from slipping off the lifting seat 6, thus enabling the metal conveying pipe 11 to achieve a good rotation effect. This, in turn, causes the annular pipe 12 to drive multiple high-pressure nozzles 14 to rotate, achieving a good flushing effect on the inner wall of the feed inlet 2.

[0029] In this embodiment, as shown in the appendix Figure 1 , 2 As shown, the surface of the support frame 3 has two sliding grooves 19, and a sliding rod 20 is fixedly installed inside each of the two sliding grooves 19. A slider 21 is slidably installed on the outside of the sliding rod 20. The slider 21 is fixedly installed at the bottom of the movable seat 4. A mounting seat 22 is fixedly installed on the top of the support frame 3 and on one side of the movable seat 4. Two electric push rods 23 are fixedly installed on the surface of the mounting seat 22, and the output ends of the two electric push rods 23 are fixedly connected to the outer wall of the movable seat 4.

[0030] Specifically, in this structure, two electric push rods 23 can push the movable seat 4 toward or away from the feed inlet 2, so that the slider 21 slides and is guided outside the slide rod 20, providing power for the movement of the movable seat 4.

[0031] In this embodiment, as shown in the appendix Figure 1 , 3As shown, two sets of support blocks 24 are fixedly installed on the outer wall of the support plate 5, and the number of support blocks 24 in each set is set to two. A lead screw 25 is rotatably installed between the two support blocks 24, and a guide rod 26 is fixedly installed between the other two support blocks 24. A drive motor 27 is provided at the top of the lead screw 25. The drive motor 27 is fixedly installed on the top of the corresponding support block 24, and the output end of the drive motor 27 is fixedly connected to the lead screw 25. The lead screw 25 and the slide rod 20 are respectively threaded and slidably connected to the lifting seat 6.

[0032] Specifically, in this structure, the drive motor 27 drives the lead screw 25 to rotate between the two support blocks 24, so that the lifting seat 6 can be lifted and lowered under the action of the guide rod 26. This allows the rotary flushing structure to be extended into the inside of the feed inlet 2 for rinsing, or the rotary flushing structure to be extended out from the inside of the feed inlet 2.

[0033] In this embodiment, as shown in the appendix Figure 1 As shown, a controller 28 is installed on the outer wall of the support frame 3 by screws. The controller 28 is electrically connected to the electric push rod 23, the drive motor 27, the high-pressure pump 8 and the rotary motor 18 respectively. The controller 28 can control the operation of each power device to achieve intelligent control.

[0034] Working principle of this utility model:

[0035] This application provides an intelligent cleaning structure for the feed channel of a rotary valve. In actual use, once a large amount of material is attached to the inner wall of the feed port 2 of the rotary valve body 1 and needs to be cleaned, the operation of the rotary valve body 1 is first turned off. The controller 28 controls the electric push rod 23 to move and push the moving seat 4 towards the feed port 2. At this time, the drive motor 27 runs, so that the lifting seat 6 drives the rotary flushing structure into the interior of the feed port 2 and uses the rotary flushing structure to flush the interior of the feed port 2.

[0036] After rinsing, in order not to affect the normal use of the rotary valve body 1, the lifting seat 6 lifts the rotary flushing structure out of the feed port 2, and moves the rotary flushing structure away from the rotary valve body 1 by the moving seat 4.

[0037] It should be noted that all contents not described in detail in the specification are existing technologies known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used. Electrical control components not mentioned in this technical solution are existing technologies and are therefore not shown in the figures, and will not be described here.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
