Description

Technical Field

[0001] This utility model relates to the field of horizontal sand mill cooling technology, specifically a rapid cooling device for a horizontal sand mill used in seed coating agent production. Background Technology

[0002] Seed coating agents require that the active ingredients be released gradually without causing toxicity to crop germination and growth. The seed coating film must be permeable to water and air, and must not affect seed life and respiration. Seed coating agents are characterized by high efficiency, economy, safety, long-lasting effect, and multifunctionality. The horizontal sand mill integrates the best features of current domestic and foreign models, and has the advantages of high efficiency, strong continuous operation, low pollution, reliable automatic control, low cost, compact structure, elegant appearance, and convenient use and maintenance. In particular, it has strong practicality and can be applied to industries such as paint, ink, pharmaceuticals, food, cosmetics, and pesticides.

[0003] In the production of seed coating agents, horizontal sand mills are key grinding equipment. However, the heat generated by high-speed operation can lead to problems such as deactivation of active ingredients and excessive energy consumption. At the same time, high temperature can also easily cause equipment failure. Traditional cooling methods mostly use single water cooling, which is slow and the horizontal sand mill is prone to overheating. To address this, we propose a rapid cooling device for horizontal sand mills used in seed coating agent production. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a rapid cooling device for a horizontal sand mill used in seed coating production. The device uses water cooling with an annular cooling pipe and air cooling inside the protective shell to quickly remove heat from the inside of the horizontal sand mill. The device also uses liquid nitrogen supplied to the inside of the horizontal sand mill to expand and absorb heat, thereby achieving instantaneous cooling of the inside. This can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid cooling device for a horizontal sand mill used in seed coating agent production, comprising a shell and a cooling unit;

[0009] The liquid pump is started to deliver coolant to the inside of the annular cooling pipe to quickly cool the inside of the shell, while the semiconductor cooler can remove the heat from the returning coolant to increase the cooling effect of subsequent cycles.

[0010] Furthermore, the cooling unit also includes a nozzle, a delivery pump, a tank rack, a liquid nitrogen tank, and a support plate. The tank rack is fixed to the rear side of the liquid tank, and the liquid nitrogen tank is snapped into the inside of the tank rack.

The input end of the fan is electrically connected to the output end of the touch control panel. Rotating the locking blocks and engaging them into the locking slots fixes the protective shell to the outside of the cylindrical shell. Activating the fan allows heat to be quickly dissipated through the heat dissipation holes, preventing burns from accidental contact and ensuring effective cooling.

[0012] Furthermore, it also includes a main temperature sensor, a secondary temperature sensor, and a wireless transmitter.

The wireless transmitter can transmit the detected data to personnel for viewing in a timely manner.

[0013] Furthermore, it also includes a liquid level sensor, a locking bracket, and a locking groove. The liquid level sensor is fixed to the top surface of the tank cover. There are two locking brackets, which are rotatably installed on both sides of the top surface of the tank cover. There are two locking grooves, which are respectively opened at both ends of the front side of the tank.

[0016] 1. The coolant is pumped into the annular cooling pipe by starting the liquid pump to quickly cool the inside of the shell, while the semiconductor cooler can remove the heat from the returning coolant to increase the cooling effect of subsequent circulation.

[0017] 2. By starting the delivery pump, liquid nitrogen is quantitatively delivered into the inside of the cylinder shell. This can instantly cool down the seed coating agent being polished inside the cylinder shell, thereby preventing the temperature inside the cylinder shell from being too high and affecting the polishing effect of the seed coating agent.

[0018] 3. By rotating the locking block and inserting it into the slot, the protective shell is fixed to the outside of the cylinder shell. Starting the fan can quickly dissipate heat through the heat dissipation holes, which not only prevents people from accidentally touching it and causing burns, but also does not affect the cooling effect.
