Description

Technical Field

[0001] The present invention relates to the technical field of chemical production, and particularly relates to a calcium cyanamide automatic feeding and dust removal device and its usage method. Background Art

[0002] Calcium cyanamide (CaCN2) is an important chemical raw material and has extensive applications in fields such as agriculture and industry. In the production and use process of calcium cyanamide, the feeding link is a crucial step. Most traditional calcium cyanamide feeding methods rely on manual operation, which has problems such as high labor intensity and low efficiency. At the same time, since calcium cyanamide powder has certain toxicity and is extremely prone to dusting, a large amount of dust will be generated during the manual operation process. This will not only pose a serious threat to the physical health of the operators, such as causing respiratory diseases, etc., but also lead to the deterioration of the air quality in the production workshop, increasing the potential risk of dust explosion. In addition, it is difficult to ensure the accuracy of feeding during manual feeding, which is likely to cause waste of raw materials or inaccurate proportioning, affecting the stability of subsequent production processes and product quality.

[0003] Although there are also some automatic feeding devices on the market currently, most of these devices do not design an efficient dust removal system specifically for the characteristics of calcium cyanamide and cannot effectively solve the dust problem during the calcium cyanamide feeding process. Or the dust removal system is independent of the feeding system, resulting in a complex overall structure of the device, large floor area, high operating cost, and poor dust removal effect, and it is difficult to meet the requirements of modern green production. Therefore, there is an urgent need to design a calcium cyanamide production device that integrates automatic feeding and efficient dust removal functions to improve production efficiency and ensure production safety and environmental protection requirements. Summary of the Invention

[0019] A usage method of a calcium cyanamide automatic feeding and dust removal device, which is applicable to the calcium cyanamide automatic feeding and dust removal device described in any one of the above, and the usage method is as follows:

[0020] First, place the raw materials for calcium cyanamide processing inside the storage bin. After placing, close the sealing cover to ensure the sealing inside the storage bin.

[0021] Then, start the second motor, which drives the driving gear to rotate at the same time. The rotation of the driving gear is meshed and driven with the driven gear. The rotation of the driven gear drives the rotation of the driving roller. The rotation of the driving roller drives the conveyor belt to perform circular motion around the driven roller. The calcium cyanamide is automatically conveyed through the movement of the conveyor belt.

[0022] The rotation of the driving roller drives the rotation of the fourth pulley. The rotation of the fourth pulley drives the rotation of the third pulley through the second belt. The rotation of the third pulley drives the rotation of the transmission rod. The rotation of the transmission rod drives the rotation of the second bevel gear. When the second bevel gear rotates, it is meshed and driven with the first bevel gear. The rotation of the first bevel gear drives the rotation of the transmission disc, and at the same time drives the baffle to perform circular swing. The calcium cyanamide falling into the storage cavity is transported through the synchronous rotation of the baffle and the rotating disc.

[0023] The rotation of the rotating shaft synchronously drives the synchronous rotation of the semi-gear column. The rotation of the semi-gear column is intermittently meshed and driven with the gear disc. When the semi-gear column rotates half a turn, the gear disc rotates half a turn. When the gear disc rotates half a turn, the storage groove located below corresponds to the material passing port, so that the storage groove located below pours the calcium cyanamide raw materials into the machine body and falls into the storage cavity on the rotating disc. The storage groove located above corresponds to the feeding port of the storage bin, and at the same time, the calcium cyanamide raw materials stored inside the storage bin fall into the storage groove located above.

[0024] At the same time, start the first motor. The rotation of the first motor drives the rotation of the second pulley. The rotation of the second pulley drives the rotation of the first pulley through the first belt. The rotation of the first pulley drives the rotation of the second connecting rod. The rotation of the second connecting rod drives the rotation of the fan blade. Through the rotation of the fan blade, a negative pressure suction is generated inside the adsorption purification box. This negative pressure suction attracts the gas and dust inside the machine body through the connecting pipe. At the same time, the gas and dust attracted into the adsorption purification box are adsorbed and filtered by multiple purification adsorption plates, and the filtered gas is discharged through the discharge pipe.

[0025] Compared with the existing technology, the beneficial effects of the present invention are as follows:

[0026] 1. By installing a quantitative feeding mechanism, a feeding mechanism, and a dust reduction and adsorption mechanism, the present invention conducts quantitative feeding of calcium cyanamide and adsorbs the gas and dust during transportation. Among them, the quantitative feeding mechanism drives the quantitative feeding roller to rotate through the rotation of the first connecting rod. Through the rotation of the quantitative feeding roller, the storage tank containing calcium cyanamide rotates in a circle, thereby performing automatic unloading treatment;

[0027] [[ID=⑨]]2. By installing a conveying mechanism, a driving mechanism, and a transmission mechanism, the present invention outputs power for the equipment and automatically conveys the quantitatively fed calcium cyanamide. Among them, the conveying mechanism drives the conveyor belt to move in a circle around the driven roller through the rotation of the driving roller, thereby performing automatic feeding;

[0028] In summary, the equipment solves the problems of large labor intensity, low efficiency, and difficult accuracy guarantee in manual feeding through the quantitative feeding mechanism, improves production efficiency, avoids waste of raw materials, ensures the stability of subsequent production processes and product quality. At the same time, the dust problem during the calcium cyanamide feeding process is effectively solved through the purification and adsorption plate filtration process of the dust reduction and adsorption mechanism, avoiding the threat of dust to the health of operators, reducing the risk of dust explosion in the production workshop, and meeting the requirements of modern green production.

Then, start the second motor (501), which drives the rotation of the driving gear (502) at the same time. The rotation of the driving gear (502) is meshed and driven with the driven gear (405). The rotation of the driven gear (405) drives the rotation of the driving roller (402). The rotation of the driving roller (402) drives the conveyor belt (404) to perform a circular motion around the driven roller (403). The calcium cyanamide is automatically conveyed through the movement of the conveyor belt (404). The rotation of the driving roller (402) drives the rotation of the fourth pulley (604). The rotation of the fourth pulley (604) drives the rotation of the third pulley (602) through the second belt (605). The rotation of the third pulley (602) drives the rotation of the transmission rod (601). The rotation of the transmission rod (601) drives the rotation of the second bevel gear (603). When the second bevel gear (603) rotates, it meshes with the first bevel gear (705) for transmission. The rotation of the first bevel gear (705) drives the rotation of the transmission disk (702) and simultaneously drives the baffle (703) to swing in a circle. The lime nitrogen falling into the storage cavity is transported through the synchronous rotation of the baffle (703) and the rotating disk (702). The rotation of the rotating shaft (701) synchronously drives the synchronous rotation of the semi-gear column (704). The rotation of the semi-gear column (704) indirectly meshes with the gear disk (204) for transmission. When the semi-gear column (704) rotates half a turn, the gear disk (204) rotates half a turn. When the gear disk (204) rotates half a turn, the lower storage tank corresponds to the material passing port, so that the lower storage tank pours the lime nitrogen raw material into the interior of the machine body (1) and falls into the storage cavity on the rotating disk (702). The upper storage tank corresponds to the feeding port of the storage box (201), and at the same time, the lime nitrogen raw material stored inside the storage box (201) falls into the upper storage tank. At the same time, start the first motor (305). The start of the first motor (305) drives the rotation of the second pulley (306). The rotation of the second pulley (306) drives the rotation of the first pulley (307) through the first belt (308). The rotation of the first pulley (307) drives the rotation of the second connecting rod (302). The rotation of the second connecting rod (302) drives the rotation of the fan blade (303). The rotation of the fan blade (303) generates a negative pressure suction force inside the adsorption purification box (301). This negative pressure suction force attracts the gas and dust inside the machine body (1) through the connecting pipe (311). At the same time, the gas and dust attracted into the adsorption purification box (301) are adsorbed and filtered by a plurality of purification adsorption plates (304), and the filtered gas is discharged through the discharge pipe (309).
