Description

Technical Field

[0001] This utility model relates to the field of bamboo salt processing technology, specifically to a linear vibrating screen for bamboo salt processing. Background Technology

[0002] Bamboo salt, a functional mineral salt, is a special crystalline substance produced by calcining sea salt in bamboo tubes at high temperatures. Its main component is sodium chloride, and it is also rich in trace elements such as calcium, potassium, and iron. It possesses unique antioxidant and antibacterial properties, making it valuable for applications in health and medicine. During bamboo salt production, to ensure the purity and quality of the finished product, specialized equipment such as linear vibrating screens are used to finely sieve the calcined product, effectively removing bamboo charcoal residue, dust, and other impurities to meet pharmaceutical-grade product quality standards.

[0003] Current bamboo salt screening processes face significant technical bottlenecks: due to the electrostatic adsorption effect on the surface of bamboo salt particles, coupled with the influence of environmental humidity, particles are prone to agglomeration and sticking. This clumping problem drastically reduces screening efficiency and lowers the effective throughput of the screen; more seriously, large agglomerates can cause screen blockage, forcing frequent production line shutdowns for cleaning, which affects production efficiency and increases energy consumption. Furthermore, traditional vibrating screens lack dedicated screen cleaning devices for sticky materials, making it difficult to maintain continuous and stable screening operations. Therefore, we propose a linear vibrating screen for bamboo salt processing. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a linear vibrating screen for bamboo salt processing, which can break up agglomerated bamboo salt particles during the screening process and clean the screening screen to prevent it from clogging, thus effectively solving the problems in the background art.

[0012] Furthermore, a material outlet is provided on the front side of the feeding box, and a baffle is engaged inside the material outlet. The material outlet facilitates the user to remove the bamboo salt granules from inside the feeding box.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This linear vibrating screen for bamboo salt processing has the following advantages:

[0014] 1. The double-roller meshing structure in the crushing component crushes the agglomerated bamboo salt in real time. Combined with the lateral reciprocating motion of the moving component, the material is evenly dispersed. During the vibrating screening process, the squeezing cam and the spring reset mechanism work together to make the screen generate high-frequency linear vibration, which effectively destroys the electrostatic adsorption and agglomeration between particles and significantly improves the screening efficiency.

[0015] 2. The cleaning component uses both negative pressure suction and mechanical sweeping to simultaneously remove screen residue during the screening process. The negative pressure airflow generated by the exhaust fan draws unscreened particles back to the feed box through the extraction pipe, while the barrier screen prevents fine particles from escaping. The electric telescopic rod drives the extraction box to move along the screen, achieving full coverage cleaning of the screen surface. This design avoids frequent shutdowns caused by clogging in traditional vibrating screens, ensuring the continuous and stable operation of the bamboo salt processing production line.

[0027] The working principle of the linear vibrating screen for bamboo salt processing provided by this utility model is as follows: Before screening, bamboo salt is injected into the support frame 61. Then, the third motor 64 is started to drive the two crushing rollers 62 to rotate and crush the bamboo salt. During the crushing process, the second motor 51 is started to rotate the threaded rod 53, which drives the support frame 61 to move laterally and evenly spread the crushed bamboo salt onto the screening screen 2. Then, the first motor 42 is started to drive the extrusion cam 43 to rotate. Through the periodic contact between the cam profile and the connecting wheel 45, the mounting frame 1 is pushed to move laterally back and forth, and the spring in the reset assembly 3 is reset. Spring 36 and slide bar 34 work together to achieve elastic reset, causing the screening screen 2 to generate high-frequency linear vibration. During the screening process, qualified bamboo salt particles pass through the screen and fall into the storage box 31, and are output by belt conveyor 32. After screening, two electric telescopic rods 72 are activated to drive the material extraction box 73 to move down close to the screen surface. Then, the moving component 5 drives the support frame 61 and the material extraction box 73 to move. During the movement of the material extraction box 73, the exhaust fan 76 is activated to generate negative pressure, which sucks the bamboo salt particles remaining above the screening screen 2 into the feeding box 75 through the extraction pipe 74. In this way, the screening screen 2 can be prevented from clogging.
