Description

Technical Field

[0001] This utility model relates to the field of rotary valve technology, specifically a cleaning structure for a rotary valve for conveying highly viscous materials. Background Technology

[0002] A rotary valve is a valve device that uses rotating components (such as impellers or baffles) to achieve functions such as fluid or powder conveying, unloading, and airlocking. It is commonly used in chemical, environmental protection, and metallurgical industries, and is mainly used for sealing and unloading powder, granular materials, and highly viscous materials.

[0003] The existing Chinese patent CN218344658U, disclosed on January 20, 2023, discloses a valve core including a rotating shaft; a plurality of blades are arranged along the circumference of the rotating shaft; the blades include a rigid part and an elastic part arranged sequentially along the radial direction of the rotating shaft and in a direction away from the rotating shaft.

[0004] However, in actual use, the above-mentioned device uses blades around the rotating shaft to form a conveying valve core, and uses the gap around the valve core to store materials. When conveying highly viscous materials for a long time, material will adhere to the material. When cleaning, manual cleaning is required. There is no corresponding automatic cleaning structure, which makes cleaning inconvenient.

[0005] Therefore, we propose a novel cleaning structure for a rotary valve used for conveying highly viscous materials to solve the aforementioned technical problems. Utility Model Content

[0015] (III) Beneficial Effects Compared with the prior art, this utility model provides a cleaning structure for a rotary valve for conveying highly viscous materials, which has the following beneficial effects: 1. This utility model achieves automatic cleaning of highly viscous materials by combining a cold air drying mechanism and a pushing cleaning mechanism. The cold air from the cold air machine is sprayed out through the hollow panel of the cold air drying mechanism, which freezes and hardens the attached highly viscous materials, reducing their stickiness.

[0020] Example 1 This embodiment provides a technical solution: a cleaning structure for a rotary valve for conveying highly viscous materials, such as... Figures 1-5 As shown, it includes a rotary valve body, a feeding and rotating mechanism, a pushing and cleaning mechanism, and a cold air drying mechanism.

[0021] The rotary valve body can be installed to convey materials. The rotary valve body includes a rotary valve housing 6. The inner wall of the rotary valve housing 6 has grooves that are staggered on the left and right sides. The upper end of the rotary valve housing 6 is connected to the feed pipe 5. The feed pipe 5 can receive the material conveyed by the high-viscosity material pipe and convey it into the interior of the rotary valve housing 6. The lower end of the rotary valve housing 6 is connected to the discharge pipe 4. The high-viscosity material temporarily stored inside the rotary valve housing 6 can be discharged through the discharge pipe 4. The rotary valve housing 6 is rotatably installed with a smooth inner wall valve core. The rotary valve housing 6 can temporarily store high-viscosity material and rotate to feed it through the smooth inner wall valve core. The smooth inner wall valve core includes a feeding impeller 1 and a smooth inner wall feeding chamber 11. The feeding impeller 1 has six smooth inner wall feeding chambers 11 at equal angles on its circumference, which can temporarily store highly viscous materials. The feeding impeller 1 is rotatably installed in the middle of the inside of the rotary valve housing 6, and the feeding impeller 1 can rotate to feed materials inside the rotary valve housing 6.

[0022] The feeding rotation mechanism is installed at the middle of the left end of the rotary valve body with screws and can be installed and removed with tools. The feeding rotation mechanism is electrically connected to the control box via a connecting wire. The control box can control the start and stop of the feeding rotation mechanism. The feeding rotation mechanism includes a drive motor 2. A motor mounting plate 21 is fixedly connected to the periphery of the drive motor 2 for corresponding installation and connection. The drive motor 2 is installed on the outer wall of the left end of the rotary valve body 6 via the motor mounting plate 21. The drive motor 2 can stably drive the outer wall of the left end of the rotary valve body 6. An assembly key shaft 22 is fixedly connected to the output shaft end of the drive motor 2. When the output shaft of the drive motor 2 rotates, it can drive the assembly key shaft 22 to rotate. When the assembly key shaft 22 rotates, it can drive the feeding impeller 1 connected to it to rotate and feed material.

[0023] Example 2 This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figures 1-4As shown, to further better realize this utility model, the following arrangement is specifically adopted: the pushing cleaning mechanism is movably installed on the inner side of the lower end of the rotary valve body, and can be moved to push and clean. The pushing cleaning mechanism includes a first electric telescopic cylinder 3, and a cylinder mounting plate 33 is fixedly connected to the periphery of the first electric telescopic cylinder 3, which can be correspondingly installed and connected. The first electric telescopic cylinder 3 is installed and connected to the outer wall of the left end of the rotary valve housing 6 through the cylinder mounting plate 33. The first electric telescopic cylinder 3 can stably extend and retract on the rotary valve housing 6. An assembly screw plate 32 is fixedly connected to the telescopic rod end of the first electric telescopic cylinder 3. When the telescopic rod of the first electric telescopic cylinder 3 is extended, it can drive the assembly screw disk 32 to move inward. The assembly screw disk 32 is equipped with a movable scraper 31 by screws. The assembly screw disk 32 can drive the movable scraper 31 to move inward. The movable scraper 31 can move accordingly in the smooth inner wall feeding chamber 11. When moving, it cleans the material that has been freeze-dried on the inner wall of the feeding impeller 1. The cleaned high-viscosity material is discharged under gravity. The movable scraper 31 is sleeved in the groove on the lower inner wall of the rotary valve housing 6, and the outer ends are aligned, thereby avoiding obstruction when the feeding impeller 1 rotates to feed.

[0024] The cold air drying mechanism is fixedly connected to the inner side of the upper end of the rotary valve body. The cold air drying mechanism is connected to the industrial air conditioner. The cold air drying mechanism includes a hollow cover plate 72. A perforated panel 7 is fixedly connected to the inner end of the hollow cover plate 72. The cold air inside the hollow cover plate 72 can be sprayed out through the mesh of the perforated panel 7. The perforated panel 7 is fixedly connected to the groove on the inner wall of the upper end of the rotary valve body 6, and can be stably installed. An air inlet connecting pipe 71 is fixedly connected to the outer end of the hollow cover plate 72. The air inlet connecting pipe 71 can transport cold air into the hollow cover plate 72. The air inlet connecting pipe 71 is connected to the cold air discharge pipe of the industrial air conditioner and can receive the cooling gas accordingly.

[0025] The hollow panel 7 and the movable scraper 31 have the same shape and size, and the shape and size of the hollow panel 7 and the movable scraper 31 correspond to the shape and size of the smooth inner wall feeding cavity 11. The perforated panel 7 is located at the feed inlet of the rotary valve housing 6, allowing for cold air drying from the top. The movable scraper 31 is located at the discharge outlet of the rotary valve housing 6, allowing for direct discharge after cleaning.

[0026] Working principle: In use, first fix the rotary valve housing 6 in the designated working position through the reserved mounting hole, connect the feed pipe 5 to the high-viscosity material conveying pipe, and connect the discharge pipe 4 to the subsequent material receiving equipment. Connect the air inlet connection pipe 71 to the cold air discharge pipe of the industrial air conditioner to ensure smooth cold air delivery. Connect the feeding rotation mechanism and the pushing cleaning mechanism through the control box to complete the equipment assembly and adjustment.

[0027] During normal conveying, the control box starts the drive motor 2, which drives the feeding impeller 1 to rotate inside the rotary valve housing 6 via the assembly key shaft 22. High-viscosity materials enter the rotary valve housing 6 through the feed pipe 5 and fall into the feeding chamber 11 on the smooth inner wall of the feeding impeller 1. As the feeding impeller 1 rotates, it moves to the discharge pipe 4 and is discharged under gravity, thus realizing material conveying.

[0028] When cleaning is required, feeding is paused, and the industrial chiller is started. Cold air enters the hollow cover plate 72 through the air inlet connection pipe 71 and is evenly sprayed into the smooth inner wall feeding chamber 11 of the feeding impeller 1 through the mesh of the perforated panel 7, causing the attached highly viscous material to freeze and harden, reducing its stickiness. After freezing is complete, the control box starts the first electric telescopic cylinder 3, whose telescopic rod extends, driving the assembly screw disc 32 and the movable scraper 31 to move into the rotary valve housing 6. The movable scraper 31 corresponds to the shape of the smooth inner wall feeding chamber 11, accurately scraping off the hardened material on the inner wall of the chamber. The scraped material is discharged through the discharge pipe 4.

[0029] The wiring diagrams of components such as the drive motor 2 and the first electric telescopic cylinder 3 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use, so the control method and wiring layout will not be explained in detail.

[0030] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
