Description

Technical Field

[0001] This utility model relates to the technical field of devices for preventing material overflow, specifically a device that has the function of preventing material overflow from the container and reducing dust. Background Technology

[0002] The production mode of the crushing process is intermittent. Currently, the existing technology relies on manual observation of the material level in the hopper and on-site operation of the equipment to control the feeding amount. Continuous and automated production has not been achieved. The process of adding materials depends entirely on manual operation, which is cumbersome and requires personnel to climb up and down the equipment to observe the material level in the hopper, resulting in low safety.

[0003] The material after crushing is insoluble in water, very fine, and easily blown away. There is a lot of dust in the production site, and the material is prone to overflowing. The automation level is low, and the on-site working environment is poor. In addition, because the feed opening of the conical double helix mixer is small, there will be residue in the conical double helix mixer when processing new material after the previous processing is completed, resulting in the material having certain impurities.

[0004] Therefore, this utility model proposes a device with the function of preventing material overflow and reducing dust to solve the above problems. Utility Model Content

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

[0014] This invention relates to a device that prevents material overflow and reduces dust. A level gauge is added to the upper part of the hopper of a conical double-helix mixer. The conveyor motor and crushing device are controlled based on the material level. When the material level in the hopper reaches the lower contact point of the level gauge, an interlocking action is triggered, cutting off power to the conveyor motor and crushing device. This prevents material from overflowing and reduces the risk of dust reaching the lower explosion limit if the hopper is full. The detachable structure of the lower conical double-helix cylinder allows for timely processing of the material in the mixer if the interlocking mechanism fails, reducing material waste. The detachable structure of the lower conical double-helix cylinder also facilitates cleaning after material processing, reducing impurities. Attached Figure Description

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] For example, please refer to Example 1. Figures 1-2 This utility model provides a technical solution: a device with the function of preventing material overflow and reducing dust, including a storage tank 1, a conveying pipe 2, a conveying motor 3, a crushing device 4, an iron remover 5, a dust collector 6, a conical double spiral mixer 7, a mixing and stirring motor 8, and a dust removal fan 9; the storage tank 1 is connected to the bottom of the conveying pipe 2, and the conveying pipe 2 is connected in sequence to the crushing device 4, the iron remover 5, and the dust collector 6;

[0022] The bottom of the dust collector 6 is connected to the conical double helix mixer 7 via the conveying pipe 2; a mixing motor 8 is installed above the conical double helix mixer 7; a dust collector fan 9 is connected to the side of the dust collector 6 via the conveying pipe 2; a level gauge 701 is installed above the inner wall of the conical double helix mixer 7; a clamping block 702 is installed below the conical double helix mixer 7; a protrusion 704 is installed below the clamping block 702, and a conical double helix lower cylinder 707 is fixedly connected below the protrusion 704.

[0023] In practical use, on-site operators first compare the large powder list and prepare all the materials to be mixed. After receiving the notification, the control room personnel turn on the dust collector 6, dust collector fan 9, crushing device 4, iron remover 5, and conveyor motor 3 in sequence. Then, the on-site personnel begin to feed solid materials. After being crushed by the crushing device 4, the materials are transferred from the dust collector 6 to the hopper of the conical double spiral mixer 7. In the hopper, the materials are further mixed and blended. At this time, the materials are fine, slippery, and insoluble in water, and are easy to form dust. When the material in the hopper reaches the contact point at the lower end of the level gauge 701, the interlock action is triggered, and the conveyor motor 3 and crushing device 4 are automatically shut down to prevent overflow. At this time, the dust collector 6 is running normally, thereby realizing the automated control of the hopper material level, reducing the risk of human intervention, controlling the occurrence of overflow, and improving the on-site working environment.

[0024] For example, see Example 2. Figures 2-3Based on Example 1, the inner wall of the locking block 702 and the inner wall of the protrusion 704 are on the same plane; the locking block 702 is symmetrically provided with limiting blocks 703; the upper end face of the protrusion 704 is provided with a locking groove 705, and the outer side of the locking groove 705 is symmetrically provided with limiting grooves 706; the locking block 702 and the locking groove 705 are adapted to engage; the limiting block 703 and the limiting groove 706 are engaged; the limiting block 703 is provided with a fixing bolt 708 through it, and the two are connected by threads; the fixing bolt 708 is provided with the protrusion 704 through it, and the two are connected by threads.

[0025] In practical use, the limiting blocks 703 symmetrically arranged on the card block 702 are first matched and engaged with the limiting grooves 706 symmetrically arranged on the outer side of the card slot 705. At this time, the threaded through holes are aligned. Then, the fixing bolts 708 are tightened. After completing one material processing, when processing new material, the fixing bolts 708 are loosened and the conical double helix lower cylinder 707 is removed. The opening is large, which is convenient for cleaning and can prevent material waste in the conical double helix mixer from being processed in time when the interlocking reaction fails.

[0026] For example, see Example 3. Figure 4 Based on Example 2, the fixing bolt 708 includes a bolt handle 7081, a bolt limiting block 7082, and a threaded post 7083. The bottom end of the bolt handle 7081 is fixedly connected to the bolt limiting block 7082; the bottom end of the bolt limiting block 7082 is fixedly connected to the threaded post 7083; the protrusion height of the bolt limiting block 7082 is the same as the groove height of the limiting groove 706.

[0027] In actual use, since the thickness of the limiting block 703 is lower than the groove depth of the limiting groove 706, the bolt limiting block 7082 is designed so that after the fixing bolt 708 is tightened, the bolt handle 7081 is still higher than the top surface of the protrusion 704, which makes it easy to disassemble and install using the bolt handle 7081.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
