Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of edible salt production devices, in particular to an auxiliary anti-caking device for edible salt. Background Art
[0002] Table salt is an indispensable condiment in daily life. It is not only used for seasoning, but also has certain effects on human health, such as maintaining fluid balance, nerve conduction and muscle function.
[0003] Edible salt is primarily produced by drilling wells into underground salt formations and pumping underground brine to the surface, or by excavating chambers within the salt formations to collect the brine. The collected raw salt brine is then processed and purified to remove impurities and harmful substances. The main processes include raw salt crushing, impurity removal, dissolution, filtration, and evaporation. Raw salt crushing is the process of pulverizing raw salt particles into a fine powder. Impurities can be removed by adding chemicals or using physical methods. Dissolution and filtration involve dissolving raw salt in water and filtering to remove suspended matter and impurities. Evaporation involves evaporating the dissolved salt solution to produce pure salt crystals. Finally, the purified salt solution is dried to produce dried salt crystals. Drying methods include natural drying and mechanical drying. Natural drying utilizes natural air drying, while mechanical drying uses specialized drying equipment such as drying towers or fluidized bed drying. In order to prevent salt particles from sticking together during the bagging, transportation and storage of dried edible salt, air is continuously introduced. However, the current way to introduce air is to directly insert the air pipe into the salt pile. Salt particles easily accumulate and clog the air pipe, resulting in a decrease in air intake and the need for frequent maintenance.
[0004] Therefore, those skilled in the art are committed to developing an auxiliary anti-caking device for edible salt to reduce the blockage of the air pipe when air is introduced into the salt pile and improve the ventilation efficiency. Utility Model Content
[0005] The technical problem to be solved by the utility model is to provide an auxiliary anti-caking device for edible salt, which can reduce the blockage of air pipes when air is introduced into a salt pile and improve the ventilation efficiency.
[0006] The technical solution of the utility model to solve the above technical problems is as follows:
[0007] An auxiliary anti-caking device for edible salt, comprising
[0008] A conveying cylinder having a conveying cavity, and an upper end of the conveying cylinder is connected to a refined salt conveying assembly;
[0009] An automatic metering component, which is installed at the lower end of the conveying cylinder and is electrically connected to the control device;
[0010] An anti-knot component is installed in the conveying cavity, and the anti-knot component has a plurality of spray ports for spraying dry cold air. The anti-knot component is connected to an air control component, and the air control component is installed on the outer wall of the conveying cylinder and is electrically connected to the control device.
[0011] The beneficial effect of adopting the above scheme is: when the refined salt conveying component conveys refined salt to the automatic metering component through the conveying cylinder, the control device automatically controls the amount of dry and cold air introduced into the conveying cylinder, and sprays it evenly through multiple spray ports. The dry and cold air takes away the heat and moisture in the refined salt, reducing adhesion and clumping; at the same time, the dry and cold air is evenly sprayed from multiple spray ports, increasing the contact area between the dry and cold air and the refined salt, while reducing the clogging of the dry and cold air outlet by salt particles.
[0012] On the basis of the above technical solution, the present invention can also be improved as follows.
[0013] Furthermore, the anti-knot assembly includes an air cylinder, which is cylindrical, and a plurality of spray ports are arranged at intervals on the outer peripheral wall of the air cylinder. The air cylinder is connected to the air control assembly through an air pipe.
[0014] The beneficial effect of adopting the above further solution is that dry cold air is evenly sprayed from multiple spray ports, which increases the contact area between the dry cold air and the refined salt, and is conducive to quickly taking away the heat and moisture in the refined salt.
[0015] Furthermore, a shielding member is installed at the upper end of the air cylinder. The shielding member is conical in shape, and the bottom diameter of the shielding member is larger than the diameter of the air cylinder.
[0016] The beneficial effect of adopting the above further solution is that the conical shielding member not only facilitates the sliding of salt particles and reduces resistance, but also reduces the possibility of salt particles directly sliding into the spray port and causing blockage.
[0017] Furthermore, the air control component is connected to a dry cold air preparation device.
[0018] The beneficial effect of adopting the above further solution is that the dry cold air preparation device is used to convey the dry cold air into the conveying cylinder.
[0019] Furthermore, the dry cold air preparation device includes an air compressor, and the air outlet end of the air compressor is sequentially connected to an air condensation component, an air drying component and the air control component.
[0020] The beneficial effect of adopting the above further solution is that the compressed air generated by the air compressor is cooled and initially dehumidified by the air condensing component, and then further dehumidified by the air drying component before being transported to the air control component.
[0021] Furthermore, the air condensing assembly includes an air tank, the lower side of the air tank is connected to the air compressor through a connecting pipe, the upper end of the air tank is connected to the air drying assembly through a connecting pipe, and an electromagnetic relief valve is installed at the bottom of the air tank, and the electromagnetic relief valve is electrically connected to the control device;
[0022] A cooling coil is installed in the air tank, and both the inlet and outlet ends of the cooling coil extend out of the air tank. The inlet and outlet ends of the cooling coil are connected to a cooling device.
[0023] The beneficial effect of adopting the above-mentioned further scheme is that after the compressed air is transported into the air tank, the coolant in the cooling coil cools the compressed air in the air tank, reducing the temperature of the compressed air. At the same time, the temperature of the compressed air is reduced so that the water in the air is analyzed and remains in the air tank. The control device controls the electromagnetic residual valve to open at a time to release the moisture in the air tank, thereby reducing the moisture content in the compressed air.
[0024] Furthermore, the air drying assembly includes a first drying tank and a second drying tank, the lower sides of the first drying tank and the second drying tank are connected to the air condensation assembly, the upper sides of the first drying tank and the second drying tank are connected to the air control assembly, and the first drying tank and the second drying tank are both installed with at least one drying layer.
[0025] The beneficial effect of adopting the above further solution is that the first drying tank and the second drying tank are used alternately, and the drying layer in the drying tank further absorbs moisture in the compressed air, thereby reducing the moisture content in the compressed air.
[0026] Furthermore, a heating pipe and a heating device are connected to the lower sides of the first drying tank and the second drying tank, and an exhaust pipe is connected to the upper ends of the first drying tank and the second drying tank.
[0027] The beneficial effect of adopting the above further solution is that the heating pipe is used to pass heated gas into the drying tank to regenerate the drying layer and improve the water absorption efficiency of the drying layer. BRIEF DESCRIPTION OF THE DRAWINGS

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.
[0037] like Figure 1 、 Figure 2 and Figure 3 As shown, a salt auxiliary anti-caking device includes:
[0038] The conveying cylinder 1 has a conveying cavity 2, and the upper end of the conveying cylinder 1 is connected to a refined salt conveying component;
[0039] Automatic metering component 3, which is installed at the lower end of the conveying cylinder 1 and is electrically connected to the control device;
[0040] The anti-knot component 4 is installed in the conveying chamber 2, and the anti-knot component 4 has multiple spray ports 5 for spraying dry cold air. The anti-knot component 4 is connected to the air control component 6, and the air control component 6 is installed on the outer wall of the conveying cylinder 1 and is electrically connected to the control device.
[0041] In the present utility model, when the refined salt conveying component conveys refined salt to the automatic metering component 3 through the conveying cylinder 1, the control device (not shown in the figure) automatically controls the amount of dry cold air introduced into the conveying cylinder 1, and sprays it evenly through multiple spray ports 5. The dry cold air takes away the heat and moisture in the refined salt, reducing adhesion and agglomeration; at the same time, the dry cold air is evenly sprayed from the multiple spray ports 5, increasing the contact area between the dry cold air and the refined salt, and reducing the blockage of the dry cold air outlet by salt particles.
[0042] like Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, the anti-caking component 4 includes an air cylinder 7, which is hollow cylindrical. A plurality of spray ports 5 are spaced apart on the outer wall of the air cylinder 7. The diameter of the spray ports 5 is smaller than the diameter of the refined salt particles, and the spray ports 5 are arranged obliquely downward to reduce the entry of salt particles into the spray ports 5. The air cylinder 7 is connected to the air control component 6 through an air pipe. A shielding member 8 is also installed on the upper end of the air cylinder 7. The shielding member 8 is conical, and the bottom diameter of the shielding member 8 is larger than the diameter of the air cylinder 7. The conical shielding member 8 not only facilitates the sliding of salt particles to reduce resistance, but also reduces the direct sliding of salt particles into the spray ports 5 to cause blockage.
[0043] like Figure 2 As shown, in another embodiment, the air control assembly 6 is connected to a dry and cold air preparation device. Specifically, the dry and cold air preparation device includes an air compressor 9, which can be a twin-screw air compressor. The air outlet of the air compressor 9 is sequentially connected to an air condensing assembly 10, an air drying assembly 11, and the air control assembly 6.
[0044] In the embodiment, the air condensing component 10 includes an air tank 12, the lower side of the air tank 12 is connected to the air compressor 9 through a connecting pipe, the upper end of the air tank 12 is connected to the air drying component 11 through a connecting pipe and a main air valve, and an electromagnetic drain valve 13 is installed at the bottom of the air tank 12, and the electromagnetic drain valve 13 is electrically connected to the control device. The control device controls the electromagnetic drain valve 13 to open at intervals to discharge the moisture at the bottom of the air tank 12, and a cooling coil 14 is installed in the air tank 12, the cooling coil 14 is close to the upper side of the air tank 12, and the inlet and outlet ends of the cooling coil 14 extend out of the air tank 12, and the inlet and outlet ends of the cooling coil 14 are connected to a cooling device, and the cooling device can be a water cooling device or a gas cooling device. The cooling water or cooling gas enters the cooling coil 14 through the cooling device and absorbs the heat in the air tank 12 and then returns to the cooling device for cooling, and the cycle is repeated, thereby reducing the temperature of the compressed air in the air tank 12.
[0045] The air drying assembly 11 includes a first drying tank 15 and a second drying tank 16. The first and second drying tanks 15, 16 utilize the same structure: one set of drying tanks dries compressed air, while the other set regenerates it. The lower sides of the first and second drying tanks 15, 16 are connected to the air condensing assembly 10, and the upper sides of the first and second drying tanks 15, 16 are connected to the air control assembly 6. Each of the first and second drying tanks 15, 16 is equipped with at least one drying layer 17 filled with molecular sieves or silica gel.
[0046] To facilitate regeneration of the molecular sieve or silica gel within the drying layer 17, a heating tube 18 and a heating device are further connected to the lower sides of the first drying tank 15 and the second drying tank 16. The heating device transports heated gas through the heating tube 18 into the first drying tank 15 and the second drying tank 16. The heating temperature is generally 150°C to 250°C, causing moisture adsorbed by the molecular sieve or silica gel to evaporate.
