Description

Technical Field

[0001] The utility model relates to a salt sorting and feeding device, belonging to the field of edible salt processing. Background Art

[0002] Edible salt can be classified into well salt, sea salt, pond salt, rock salt, etc. Its ingredients include iron, calcium, zinc, potassium, sodium, iodine and other nutrients. The edible salt people use is a type of salt, which refers to salt rich in sodium, that is, sodium chloride. Salt is also an important element that the human body cannot lack, and it has the function of regulating human activities.

[0003] The production process of edible salt involves extracting sodium chloride from raw materials, then processing and treating it to finally obtain edible salt that meets food safety standards; the processing and treatment process includes collecting raw materials, dissolving, filtering, evaporating, crystallizing, harvesting, washing, centrifuging, drying, screening and packaging. In the screening step, most of the screening is done using a sorting machine, which is a machine that grades and screens products by weight.

[0004] The particles of edible salt are relatively small. The material enters the sorting machine through the feeding device and is more likely to accumulate at the feed point. Even if there is a vibrator to drive the screen to vibrate and cause the edible salt to move, the production efficiency is relatively low for mass-produced edible salt.

[0005] Therefore, the utility model provides a salt sorting and unloading device utilizing wind-assisted feeding. Utility Model Content

The hopper 10 is directly installed at the feed of the sorting machine or is erected directly above the feed of the sorting machine through a frame 30;

[0034] The air delivery system 20 includes a fan 201, an air duct 202 and an air supply cylinder 203. The fan 201 is installed on the frame 30 or at the bottom of the sorting machine. The output end of the fan 201 is connected to the air supply cylinder 203 through the air duct 202. The air cylinder 203 is installed at the bottom directly below the feed port 101 of the hopper 10.

[0035] The utility model can be independently separated and suspended above the sorting machine, and can also be directly installed at the feed of the sorting machine, which is convenient for disassembly and assembly. In addition, in view of the particle size and quality characteristics of edible salt, in order to avoid the accumulation of edible salt at the feed, the air delivery system 20 is directly assisted to deliver the edible salt to the screen far away from the feed rear 101, thereby reducing the time for the edible salt to travel from the screen feed to the discharge, thereby improving production efficiency.

[0036] The hopper 10 comprises a feed portion 102 and a discharge portion 103, wherein the discharge portion 103 is obliquely arranged at one end of the feed portion 102, and the discharge portion 103 is connected to the inside of the feed portion 102;

[0037] The feed port 101 and the discharge port 104 are provided. The feed port 101 is opened on the top end surface of the feed part 102 , and the discharge port 104 is provided at the tail end of the discharge part 103 which is not connected to the feed part 102 .

[0038] Through the design of the feeding part 102 and the discharging part 103 of the hopper 10, the inclined discharging part 103 will further reduce the accumulation of edible salt at the feeding part 102, and continuously discharge the material along with the vibration of the sorting machine, thereby increasing the discharging speed of the edible salt.

[0039] Furthermore, a strip-shaped air outlet 122 is provided at the bottom end of the inner wall corresponding to the first side surface 121 of the feed portion 102 to facilitate air supply by the air supply system 20 .

[0040] Furthermore, an air supply tube 203 is installed inside the side wall of the feed part 102 corresponding to the air outlet 122. The air supply tube 203 cooperates with the air delivery system 20 to smoothly deliver air and assist in delivering the materials.

[0041] The air supply cylinder 203 includes a cylinder 231, which is a hollow cylinder. One end of the cylinder 231 is a closed end, and the other end is connected to the air duct 202 to prevent air leakage. The wind energy sent by the fan 201 is directly discharged from the air outlet 232.

When edible salt is poured into the feeding port 101, there is no problem of edible salt entering the air delivery system 20.

[0045] In one specific implementation manner, the cross-sectional shape of the blocking portion 105 is a right triangle. Compared with an acute triangle and an isosceles triangle, a right triangle is easier to process and fix.

[0046] Furthermore, a plurality of mounting grooves 151 are formed on one of the right-angled side surfaces of the blocking portion 105 , and are slidably matched with a fixing block 152 welded to the side wall of the feeding portion 102 .

[0047] Furthermore, the length L1 of the installation groove 151 is one half to two thirds of the length L2 of the right-angle side of the blocking portion 105 .

[0048] The blocking part 105 of the utility model is slidably mounted on the fixing block 152 through the installation groove 151. Due to the height design of the installation groove 151, the blocking part 105 can be hung on the fixing block 152, which is convenient and simple to install and easier to operate.

[0049] In one specific implementation manner, the blocking portion 105 is hollow inside and has a small mass, so it is easy to assemble and disassemble.

[0050] In one specific embodiment, the blocking portion 105 is made of acid-resistant steel material, which is resistant to corrosion by chemical corrosive media (acid, alkali, salt, etc.), thereby increasing the service life.

[0051] 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.
