[0033] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0034] Reference Figure 1-Figure 4 As shown, this embodiment provides a specific implementation method for a rolling device for salt production, including a lower hopper 10, a grinding unit 20 and an atomization system 30. The lower end of the lower hopper 10 is equipped with a grinding unit 20 for grinding salt. The atomization system 30 vertically penetrates from a position deviating from the center of the top surface of the lower hopper 10 and is then suspended at the top of the lower hopper 10.
[0035] Furthermore, an inlet 101 for entering materials is opened on the top surface of the lower hopper 10;
[0036] The atomization system 30 includes an atomization nozzle 301, an air inlet pipe 302, a water inlet pipe 303, and a collection pipe 304. The collection pipe 304 is located at the top of the lower hopper 10, and the atomization nozzle 301 is installed on the side of the collection pipe 304 facing the center of the lower hopper 10. The top surface of the collection pipe 304 is vertically connected to the air inlet pipe 302 and the water inlet pipe 303. The ends of the air inlet pipe 302 and the water inlet pipe 303 pass through the top surface of the lower hopper 10 and are connected to the external fan and water source.
[0037] The utility model sets a grinding unit 20 for grinding salt at the bottom of the lower hopper 10, and installs an atomizing system 30 at the inlet 101 at the top of the lower hopper 10. After the salt enters the hopper, atomizing gas is sprayed out through the atomizing nozzle 301 of the atomizing system 30, which will increase the moisture content of the sea salt and reduce the degree of crystallization. The distance between the wet sea salt particles will increase, and the salt particles will be more easily ground after gradually moving downward in the lower hopper 10.
[0038] Furthermore, the air inlet pipe 302 near the atomizing nozzle 301 is equipped with an air pressure regulator 305 and an air valve 306 in sequence. The air pressure regulator is a device for controlling gas pressure. Its principle is to control the area through which the gas flows by adjusting the opening of the valve, thereby adjusting the gas pressure. The air switch valve is used to control the flow and direction of the gas, and can realize functions such as opening and closing, pressurizing, and decompressing the gas, thereby controlling the spraying of the atomizing nozzle 301.
[0039] Furthermore, an air filter 307 is installed between the air pressure regulator 305 and the air valve 306. The air filter 307 includes an outer cylinder and filter cotton accommodated inside the outer cylinder, which is used to filter impurities in the air to avoid clogging of the atomizing nozzle 301 during air intake.
[0040] Furthermore, the collecting pipe 304 is a cuboid with a closed bottom end face, which is convenient for processing and production. The collecting pipe 304 is made of PVC material, which can withstand a certain concentration of hydrochloric acid at room temperature. In actual use, its service life can be extended.
[0041] The inner cross-section of the discharge port of the lower hopper 10 is rectangular, which is convenient for installing the grinding unit 20 inside.
[0042] Furthermore, the grinding unit 20 includes a fixed roller 201, and the front and rear ends of the fixed roller 201 penetrate the outer side of the lower hopper 10 and are locked on the outer wall of the lower hopper 10 by screws;
[0043] The rolling roller 202 is on the same horizontal line as the fixed roller 201, and the front end of the rolling roller 202 passes through the lower hopper 10 and is mechanically connected to the output end of the external small motor 203; the rear end of the rolling roller 202 is rotatably connected to the inner wall of the bottom end of the lower hopper 10.
[0044] Furthermore, a plurality of ridges are arranged on the outer surface of the rolling roller 202. Through the ridges arranged at intervals, when the rolling roller 202 is driven by the small motor 203, the material is driven to flow into the gap between the fixed roller 201 and the rolling roller 202. Since the gap between the two is relatively narrow, the salt with reduced surface crystallization degree will be crushed and fall into the conveying unit 40 below, and will be further broken up during the conveying process of the conveying unit 40. After being crushed and dispersed, the salt is easier to be ground.
[0045] In one specific embodiment, the height of the ridges is not higher than 0.2 mm, so as to prevent the salt from being directly embedded between two adjacent ridges during the rotation process and being directly rotated and falling into the conveying unit 40 without being crushed.
[0046] In one specific embodiment, the minimum distance between the rolling roller 202 and the outer surface of the fixed roller 201 is 0.1-0.3 mm, and the particle size of the refined salt is approximately 20-40 mesh, that is, between 0.90-1.8 mm. The material after rolling of the utility model is more easily ground into refined salt that meets the standards by a grinder.
[0047] The utility model further comprises a conveying unit 40 and a frame 50. The conveying unit 40 for conveying materials is installed on the top of the frame 50. A lower hopper 10 is vertically installed at one horizontal end of the conveying unit 40, and the other end is a discharge port 60 for discharging materials.
[0048] Further, the conveying unit 40 comprises a housing 401, a threaded conveying rod 402, a first pulley 403, a second pulley 404, a belt 405 and a motor 406;
[0049] The housing 401 is fixed to the top of the frame 50, the threaded conveying rod 402 is horizontally arranged inside the housing 401, and the first end of the threaded conveying rod 402 horizontally penetrates the housing 401 and is installed with a first pulley 403;
[0050] A second pulley 404 is rotatably connected to the bottom of the frame 50 directly below the first pulley 403, and a belt 405 is used to transmit the first pulley 403 and the second pulley 404;
[0051] The middle of the second pulley 404 is connected to the output end of the motor 406 .
[0052] After the motor 406 of the utility model is powered on, the power is directly transmitted to the threaded conveying rod 402 via the first pulley 403, the second pulley 404 and the belt 405 to drive the transmission and transportation, thereby conveying the salt under the lower hopper to the material port 60, and further breaking up the crushed salt.
[0053] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
