TECHNICAL FIELD
[0001] The utility model relates to insoluble sulphur production technical field, concretely is a kind of conveying screening device for insoluble sulphur production. BACKGROUND
[0002] Insoluble sulphur is the transparent, amorphous chain structure elastic sulphur obtained by heating sulphur powder to boiling, and then rapidly cooling in cold water. It can also be obtained by diluting superheated sulphur vapor with inert gas, spraying it into cold water mist and cooling it to below 90 degrees Celsius, or by dissolving sulphur blocks in ammonia and immediately spraying and drying. It is widely used in the production of tires and other rubber composite products as a high-grade accelerator and vulcanizing agent in the rubber industry, such as tire body compound, cushion compound, white sidewall compound, retreading, rubber hose, rubber belt and other rubber and framework material bonding compounds, and can also be used in cable, rubber roller, oil seal, rubber shoes and other rubber products. It is also used in light-colored rubber products with high sulphur consumption. Insoluble sulphur is a non-toxic, flammable yellow powder, named for its insolubility in carbon disulfide.
[0003] According to Chinese patent publication No. CN 215962617 U, a kind of insoluble sulphur production conveying device, including shell;The right side of the inner wall of the top of the shell is through communication and has feed pipe, the left side of the inner wall of the bottom of the shell is through communication and has discharge pipe, the middle part of the right side of the shell is fixedly installed with first drive motor, the motor shaft of the first drive motor is through the right side inner wall of shell and is fixedly connected with first rotating rod, the outside of the first rotating rod is fixedly installed with first spiral conveying blade. The combination of dust cover, air suction port, air suction pump, filter box and filter screen plate can prevent wind, avoid the influence of air flow on the scattering of insoluble sulphur during conveying and bagging, and can also suck the dust generated during bagging into the filter box. Through the combination of second drive motor and second spiral conveying blade, the insoluble sulphur recovered in the filter box can be reintroduced into the shell, saving resources.
[0004] However, in the production process of insoluble sulphur, the pretreatment of raw materials, especially the screening and grading of particle size, is a crucial step. The uniformity and accuracy of particle size directly affect the performance, processing efficiency and quality of the final product. The above-mentioned conveying device mainly focuses on the conveying and bagging of materials, but lacks an effective screening mechanism for the particle size distribution of sulphur raw materials. This means that the raw materials may contain particles of different sizes, which can adversely affect the product quality, processing efficiency and equipment wear during subsequent production. SUMMARY
[0005] In order to solve the above technical problems, the utility model provides a conveying and screening device for insoluble sulphur production, which can conveniently complete screening of sulphur raw materials and improve efficiency.
[0006] The technical scheme is as follows: a conveying and screening device for insoluble sulphur production, which comprises a shell, a rotating shaft connected with a motor is arranged in the shell, spiral conveying blades are arranged on the rotating shaft, a feeding frame is arranged on the upper portion of one end of the shell, characterized in that at least two sieve hole areas with different hole diameters are arranged on the bottom of the discharge side of the shell, the sieve hole diameters of the sieve hole areas increase in sequence along the conveying direction, a discharge frame is arranged below the sieve hole areas, a partition plate is fixed to the inner wall of the discharge frame to divide the discharge frame into different discharge areas, and a collecting box is arranged below each discharge area.
[0007] Further, the sieve hole areas comprise small hole sieve hole areas, medium hole sieve hole areas and large hole sieve hole areas arranged in sequence.
[0008] A discharge hopper is connected to the bottom of the discharge area.
[0009] Both ends of the shell are supported on a vertical plate, a support plate is connected to the lower portion of the vertical plate, and the collecting box is placed on the support plate.
[0010] After the utility model is adopted, sulphur particles that need to be screened are fed into the shell from the feeding frame, the sulphur particles are pushed forward by the spiral conveying blades, smaller particles can pass through smaller sieve holes and fall into corresponding discharge areas first due to the fact that the sieve hole diameters increase in sequence along the conveying direction, and larger particles continue to move forward until they pass through sieve holes with appropriate sizes and fall into collecting boxes to complete screening, thereby improving efficiency.
