Description

Technical Field

[0001] This invention belongs to the field of diatomite waste conveying technology, specifically referring to a diatomite waste conveying device. Background Technology

[0002] Diatomaceous earth, due to its high porosity, strong adsorption capacity, and stable chemical properties, is widely used in various industrial fields such as filtration, adsorption, and packing materials. The mining, processing, and recycling of diatomaceous earth generate a large amount of waste. This waste typically requires transport equipment for subsequent resource recovery or environmental treatment.

[0003] In existing technologies, screw conveyors are widely used for conveying powder or granular materials due to their simple structure, good sealing performance, and high conveying efficiency. However, when conveying diatomaceous earth waste, existing screw conveyor equipment faces the following prominent problems: 1. Blockage and residue caused by strong adhesion: Diatomaceous earth waste usually contains a certain amount of moisture and has strong adhesion. During the transportation process, the waste is very easy to adhere to and accumulate on the inner wall of the conveyor cylinder, the spiral blades and the central shaft. As the running time increases, the adhesion layer gradually thickens, which not only significantly reduces the effective cross-sectional area of ​​the conveying channel and causes a decrease in conveying efficiency, but also causes equipment jamming and overload shutdown in severe cases.

[0004] 2. Difficulty in cleaning and maintenance: Due to the adhesive properties of diatomaceous earth waste, cleaning the inside of the equipment after the conveying task is completed is a major problem. It often requires manual disassembly and scraping, which is labor-intensive, inefficient, and difficult to clean thoroughly. If the cleaning is not thorough, the residual waste will dry and harden, affecting the conveying effect of the next use, and may even contaminate the newly conveyed material due to material deterioration.

[0005] 3. Lack of effective integrated cleaning mechanism: Although some existing equipment is designed with simple anti-stick coatings or scraper structures, it is usually a passive scraping in one direction with limited effect. There is a lack of integrated solutions that can actively and reciprocatingly mechanically scrape the inner wall of the conveyor cylinder, the spiral blades and the central shaft during equipment operation, and combine it with water rinsing for deep cleaning.

[0006] Therefore, developing a new type of conveying equipment that can effectively solve the adhesion and clogging problems in the process of conveying diatomaceous earth waste, and can achieve efficient, convenient and automated internal cleaning of the equipment, has important practical significance and broad market prospects. Summary of the Invention

[0007] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a diatomaceous earth waste conveying device. This device simultaneously achieves spiral conveying, reciprocating scraping of the cylinder wall, and high-pressure water washing via a single drive source. The cleaning scraping ring continuously peels away adhering materials from the inner wall during conveying, and the trigger-activated reversal mechanism enables reciprocating scraping. Simultaneously, a pressure-pressurizing component forces water into the washing channel to spray and wash the spiral blades and shaft. This integrated solution, combining mechanical scraping and hydraulic washing, completely solves the clogging and cleaning problems caused by the strong adhesion of diatomaceous earth waste, enabling parallel conveying and self-cleaning operations, and significantly improving continuous operation capability and ease of maintenance.

[0018] The beneficial effects achieved by the present invention using the above structure are as follows: 1. Achieving efficient anti-sticking and self-cleaning to ensure smooth conveying: This invention utilizes the rotation of the rotating connection end to synchronously drive the spiral blades to rotate, which in turn drives the cleaning and scraping ring to reciprocate on the inner wall of the conveying cylinder through the locking frame. This cleaning and scraping ring can continuously and actively scrape off the diatomaceous earth waste adhering to the inner wall of the conveying cylinder, effectively preventing the accumulation and caking of materials on the inner wall, fundamentally avoiding the problem of blockage in the conveying channel caused by material adhering to the inner wall, and ensuring the long-term stability and conveying efficiency of the equipment; 2. Achieve deep and comprehensive cleaning, reducing maintenance costs: This invention not only scrapes the cylinder wall with a cleaning scraper ring, but also uses a trigger rod and switch to automatically reverse the drive motor, driving the cleaning scraper ring to move back and forth, repeatedly and comprehensively scraping and cleaning the inner wall of the conveying cylinder. At the same time, the drive gear plate drives the suction and pressurization component to draw in water and pressurize it. Finally, the spiral blades, cleaning scraper ring, and the inside of the conveying cylinder are flushed with high-pressure water through the flushing channel and flushing hole. This composite cleaning method that combines mechanical scraping and water flushing achieves deep cleaning of all easily adhered parts inside the equipment, completely solving the pain point of traditional equipment being difficult to clean, and greatly reducing the frequency and labor intensity of manual maintenance. 3. Compact structure, multiple use of power source, energy saving and efficiency improvement: This invention cleverly utilizes the rotating connection end (drive gear plate) as a core power source to simultaneously drive the material screw conveyor, the reciprocating movement of the cleaning and scraping ring, and the operation of the suction and flushing system. This multi-purpose design eliminates the need for additional drive motors for cleaning and flushing functions, simplifies the equipment structure, reduces manufacturing costs and failure rate, and also saves energy, achieving efficient energy utilization. 4. Optimize the conveying process and improve production continuity: Since the equipment can simultaneously scrape and clean the inner wall during the conveying process, and can automatically reverse conveying and rinsing when needed (such as triggering reversal or setting a cycle), the equipment can operate continuously and stably for a long time, avoiding frequent shutdowns for cleaning due to material adhesion. This not only improves the efficiency of completing single batch conveying tasks, but also makes the switching between multiple batches and different materials more convenient and cleaner, significantly improving the continuity and automation level of the overall production process.

At this time, the pressure spring 26 contracts, and the pressure ball 27 moves away from the through hole 30, causing the through hole 30 to... The water is connected to the inlet chamber 32 and then forced into the pressure chamber 29 through the pressure port 28. As water is continuously forced into the pressure chamber 29, the residual air in the pressure chamber 29 is gradually emptied, and the pressure in the pressure chamber 29 continues to accumulate and increase. When a stable high-pressure water environment is formed inside the pressure chamber 29, the high-pressure water can be quickly flushed into the outlet pipe 19 and forced into the flushing channel 38, and flushed out through the flushing hole 39 to flush the spiral blades 5, the cleaning scraping ring 10 and the inner wall of the conveying cylinder 1, achieving multiple efficient cleaning and transmission effects.
