Description

TECHNICAL FIELD

[0001] The utility model belongs to the carbon black production technical field, concretely relates to a new type carbon black special elevator import winnowing device. BACKGROUND

[0002] In the carbon black production process, the material temperature after drying is usually maintained at a high temperature of 100-150 DEG C. This temperature condition has a significant impact on the subsequent magnetic separation process. The magnetic properties of magnetic materials are due to the ordered arrangement and spin orientation of their internal electrons. When the temperature rises, the internal thermal motion of the material intensifies, leading to the disorder of the magnetic domain structure, thus causing the attenuation of the magnetic properties. Studies have shown that in the high-temperature carbon black environment, the magnetic field strength of the permanent magnet in the magnetic separation equipment may attenuate 4000-6000 Gauss, seriously weakening the adsorption capacity of the equipment to ferromagnetic impurities. This significant decline in magnetic properties directly leads to a decrease in the efficiency of magnetic separation and an increase in the content of iron impurities in the product, which cannot meet the requirements of high-end customers for product purity.

[0003] At the same time, customers in different application fields have significant differences in the dust content standards of carbon black products. Poor magnetic separation effect not only increases the iron impurities in the product, but also leads to excessive dust content. This problem often causes customer complaints, and in severe cases, even batch returns, which not only affects the market reputation of the enterprise, but also causes significant economic losses. Therefore, how to maintain the stability of the magnetic separation equipment under the condition of high material temperature and ensure the consistency of product quality has become a key technical problem to be solved in the current carbon black industry. The solution to this problem has important practical significance for improving product competitiveness and ensuring economic benefits of enterprises. SUMMARY

Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] In the description of the utility model, it should be explained that unless there are explicit provisions and limitations, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to specific circumstances.

[0023] The utility model structure includes wind selection air supplement port 1, shell 2, filter screen plate 3, carbon black material inlet 4, wind selection dust suction port 5 and inspection opening 6.

[0024] The wind selection dust suction port 5 is arranged at the top of the shell 2, the carbon black material inlet 4 is arranged at one side of the top of the shell 2, the carbon black material inlet 4 is arranged obliquely, the filter screen plate 3 is arranged in the shell 2 and below the carbon black material inlet 4, the filter screen plate 3 is arranged obliquely, the wind selection air supplement port 1 is arranged on the side wall of the shell 2, the wind selection air supplement port 1 is arranged on the side of the filter screen plate 3 away from the wind selection dust suction port 5, the setting direction of the wind selection air supplement port 1 is in horizontal state, the setting position of the wind selection dust suction port 5 is higher than the setting position of the carbon black material inlet 4 in horizontal direction, the wind selection dust suction port 5 is arranged along the vertical direction, the inspection opening 6 is arranged on the side of the shell 2, the horizontal position of the inspection opening 6 is higher than the filter screen plate 3 and lower than the height of the carbon black material inlet 4, a plurality of ventilation holes are arranged on the filter screen plate 3, and the inclination angle of the filter screen plate 3 is greater than the inclination angle of the axis of the carbon black material inlet 4.

[0025] When using, the carbon black material enters from the carbon black material inlet 4, moves downwards through the filter screen plate 3, the wind selection air supplement port 1 blows air into the shell 2, the air blows towards the carbon black material through the filter screen plate 3, the wind selection dust suction port 5 blows upwards to suck out the dust in the carbon black material. When overhauling, the inside of the shell 2 is observed through the inspection opening 6.

[0026] By using the filter screen plate 3, the air from the air supplementing air inlet 1 is used to screen the carbon black material, and at the same time, because the air and the filter screen plate 3 are in direct contact with the carbon black material, the air dust suction port 5 is used to suck away the carbon black material dust and air from the inside of the shell 2, at the same time, the filter screen plate 3 carries away a part of the heat of the carbon black material and reduces the temperature of the filter screen plate 3 by means of the air supplementing air inlet 1, the filter screen plate 3 can effectively block the falling speed of the carbon black material, and under the premise of realizing the reduction of the temperature of the carbon black material, the problem of too much dust carbon black in the packaging of finished carbon black is solved, the size distribution of the product is more in line with the requirements of customers, and the complaint frequency of customers is reduced; at the same time, because the temperature of the carbon black material is reduced, the magnetic force of the magnetic rod in the subsequent process is prevented from being reduced due to the too high temperature of the material, so that the service life of the magnetic rod is prolonged, and the production cost is reduced, compared with the conventional design of the elevator inlet on the market, the application and practical value of the device are higher.
