Description

Technical Field

[0001] The utility model relates to the technical field of feed valves, in particular to an automatic control rotary feed valve for solid particle materials. Background Art

[0002] The rotary discharge valve is a device specially used to control the flow of solid granular materials. It is widely used in chemical, food, pharmaceutical, building materials and other industries. Its main function is to quantitatively and evenly transport granular materials from storage bins or hoppers to downstream equipment or production lines through rotation. The precise control capability of the rotary discharge valve makes it particularly suitable for production processes that require high-precision metering and continuous feeding, effectively improving production efficiency and product quality.

[0003] The existing rotary discharge valve is usually composed of a valve body, a rotor, a drive device and a control system. When working, the drive device drives the rotor to rotate inside the valve body. The rotor is provided with multiple cavities for loading and conveying materials. When the rotor rotates, the material enters the cavity from the feed port above, and then with the rotation of the rotor, the material is conveyed to the discharge port below to realize the discharge.

[0004] However, most of the existing rotary discharge valves discharge materials directly and cannot release materials quantitatively. In the actual production process, due to the lack of precise quantitative control, the amount of material released often cannot meet the requirements of the production process, resulting in reduced production efficiency. In addition, excessive or insufficient material release will also affect product quality and increase production costs. Utility Model Content

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, the weight of the material in the temporary storage barrel is sensed by an electromagnetic meter. When the material reaches a certain weight, the electric slide rail drives the movable plate to slide, and then opens the load-bearing plate, so as to achieve the effect of quantitatively releasing the material. This solves the problem that most of the existing rotary discharge valves can directly discharge the material and cannot release the material quantitatively, improves the practicability of the discharge valve, and expands the application scope of the fixed-feed valve.

[0016] 2. In the utility model, the blade can cooperate with the limit spring to slide inside the sleeve, so that the blade can effectively get stuck with the material during the feeding process.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Specifically, when it is necessary to accurately and quantitatively release the material, the material is released into the temporary storage barrel 5 through the valve body 1. As the material in the temporary storage barrel 5 accumulates, the pressure on the support plate 7 gradually increases. Once the pressure on the support plate 7 reaches a preset value, the electromagnetic meter 13 will start the electric slide 9. The function of the electric slide 9 is to drive the movable plate 8 to slide at one end and rotate the other end on the outer wall of the temporary storage barrel 5, so that the support plate 7 rotates around the connecting seat 6 and opens, thereby releasing the stored material. In this process, the connecting spring 11 cooperates with the fixed plate 10 and the fixed seat 12 to provide support for the support plate 7 to ensure its stability and reliability. This not only can accurately control the amount of material released, but also enhances the durability and maintainability of the system through the use of the connecting spring 11, while also improving the practicability of the discharge valve, expanding its scope of application, and can effectively improve the accuracy and efficiency of the operation, ensuring the stability and sustainability of the production process.

[0027] Specifically, when there is leakage or other circumstances that cause the material to be overfilled after passing through the scraper 15 and there is a risk of jamming, the overfilled material will trigger the material level switch 17 behind the scraper 15, and the booster fan 16 with a filter on the valve wall behind the scraper 15 will blow in compressed air to disperse the overflowing material. When the material level is normal, the upper valve switch will be restored to continue feeding.

[0028] Reference Figure 1 , Figure 2 and Figure 3 The valve body 1 is rotatably connected to the main shaft 18, and the main shaft 18 is slidably connected to the insert plate 19; the outer wall of the insert plate 19 is fixedly connected to the sliding sleeve 20, and the inner part of the sliding sleeve 20 is slidably connected to the blade 21; the outer wall of the blade 21 is fixedly connected to the limit block 23, and the outer wall of the limit block 23 is slidably connected to the inner part of the sliding sleeve 20; a limit spring 22 is arranged inside the sliding sleeve 20, one end of the limit spring 22 is fixedly connected to the inner part of the sliding sleeve 20, and the other end of the limit spring 22 is fixedly connected to the outer wall of the blade 21;

[0029] Specifically, when it is necessary to reduce material blockage, the sleeve 20 can slide inside the main shaft 18 through the connected insert plate 19, which allows the sleeve 20 to be easily removed from the outer wall of the main shaft 18. When the material contacts the blade 21, the blade 21 can slide inward to the inside of the sleeve 20. At the same time, the limit spring 22 is compressed, and the limit block 23 limits the sliding distance of the blade 21, which effectively prevents material blockage and makes it easy to remove the blade 21 for maintenance or cleaning when necessary, thereby improving the convenience of the discharge valve and enabling operators to easily deal with possible blockage problems. At the same time, the reliability and durability of the discharge valve are enhanced.

[0030] Working principle: When it is necessary to quantitatively release the material, the material is released into the temporary storage barrel 5 through the valve body 1. As the amount of material in the temporary storage barrel 5 increases, the pressure on the support plate 7 will continue to increase. When the weight reaches a certain value, the electromagnetic meter 13 will start the electric slide rail 9 to drive one end of the movable plate 8 to slide, so that the other end of the movable plate 8 can rotate on the outer wall of the temporary storage barrel 5, thereby opening the support plate 7, wherein the support plate 7 can rotate around the connecting seat 6 to open, and at the same time, the connecting spring 11 cooperates with the fixed plate 10 and the fixed seat 12 to support the support plate 7, thereby achieving the effect of quantitative release of materials. , which improves the practicability of the discharge valve and expands the application scope of the metering valve. When it is necessary to reduce the occurrence of blockage, the insert plate 19 connected by the sleeve 20 can slide inside the main shaft 18, so that the sleeve 20 can be removed from the outer wall of the main shaft 18, and then when the blade 21 contacts the material, the blade 21 can slide inward inside the sleeve 20 and compress the limit spring 22 at the same time, wherein the limit block 23 can limit the sliding distance of the blade 21, thereby facilitating the disassembly of the blade 21 and preventing material blockage, thereby improving the convenience of the discharge valve and extending the service life of the metering valve.
