Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of iodized salt production and relates to a feeding detection device for adding iodine to table salt. Background Art
[0002] Seaweed iodized salt is a new generation of iodized salt products. 80% of the iodine in seaweed is inorganic iodine, and only 10% to 20% is in the form of organic iodine. Seaweed iodized salt has the advantages of both inorganic and organic iodine. Compared with products with inorganic chemicals as additives, seaweed iodized salt is an ideal natural seasoning iodine supplement for all people. Seaweed iodized salt has good thermal stability, which is significantly better than ordinary inorganic iodized salt, providing a good raw material for cooking. Edible iodized salt is iodized salt made by adding a certain amount of iodine agent to refined salt, crushed washing salt, and sun-dried salt. The iodine in salt can only play a biological activity in the human body after it is converted into iodine ions. Iodide is extremely unstable in nature and is easily decomposed, volatilized and ineffective. Therefore, seaweed salt is more suitable for people to eat.
[0003] Seaweed iodized salt is a salt product made by adding seaweed extract to refined edible salt. In the production process of seaweed iodized salt, the principle of quantitative addition of seaweed iodine solution is adopted. The raw salt is passed through the feeding equipment to achieve a relatively constant flow rate, and a diaphragm metering pump is used to spray a certain concentration of seaweed iodine solution. The amount of seaweed iodine solution added is adjusted steplessly in time to match the amount of raw salt. The salt after adding seaweed iodine solution is fully mixed by the mixing equipment to achieve the uniformity of the iodine content of the seaweed iodized salt, and finally the seaweed iodized salt is obtained.
[0004] However, there are still some shortcomings in the production process. When the supply of edible salt raw materials is insufficient or cut off, the metering pump cannot quickly detect the lack of material and automatically stop adding seaweed iodine solution to the mixing equipment, which may easily lead to excessively high iodine content in the iodized salt produced after the cut-off. Summary of the invention
[0005] The utility model aims to solve the problems existing in the prior art and proposes a feeding detection device for iodized salt. The technical problem to be solved by the utility model is: how to detect whether the edible salt in the feeding equipment is out of stock and stop spraying iodine liquid when the stock is out of stock.
[0006] The purpose of the utility model can be achieved through the following technical solutions: a feeding detection device for iodized salt, comprising a feeding device, a mixing device, a liquid storage tank and a metering pump, the top of the feeding device is provided with a feeding port, the bottom of the feeding device is provided with a feeding pipe connected to the feeding port, a hinged rotating shaft is provided inside the feeding pipe, and a spiral blade is provided on the outer side of the rotating shaft.

The limiting part of the bracket plays a role of limiting the detection plate, preventing one end of the detection plate from tilting too high, so that the raw salt cannot fall on the detection plate.
[0012] Compared with the prior art, the utility model has the following advantages:
[0013] 1. In this solution, when the raw salt in the feeding equipment is insufficient or cut off, the detection board cannot detect the material and automatically disconnects the proximity switch. The contact switch controls the metering pump to shut down, so that the seaweed iodine solution is no longer added to the mixing equipment, effectively ensuring the stability of the product production process.

[0021] like Figure 2 As shown, a downwardly opening discharge port 1e is provided at the top of the feeding pipe 1b, and the discharge port 1e is arranged just above the mixing inlet 2a. A fixed bracket 5 is provided on the outer side wall of the discharge port 1e, and a bolt 7 is provided on the bracket 5. The bracket 5 is fixedly connected to the discharge port 1e by the bolt 7. One end of the bracket 5 extends obliquely downward, and a pin 5b is provided on the end. A hinged detection plate 6 is provided on the pin 5b. One end of the detection plate 6 is arranged below the discharge port 1e, and an adjustable counterweight 6a is provided at the other end. A proximity switch 5a is provided on the bracket 5, and the proximity switch 5a is arranged above the detection plate 6 and close to one end of the counterweight 6a. One end of the detection plate 6 is tilted and can be abutted against the bottom of the proximity switch 5a. The proximity switch 5a is connected to the metering pump 4 and controls the start and stop of the metering pump 4. A limiting portion 5c is provided on the bracket 5, and the limiting portion 5c is arranged at the bottom of the detection plate 6 and can be abutted against the bottom of the detection plate 6.
[0022] like Figure 3 As shown, a hinged rotating shaft is provided inside the feeding pipe 1b, a spiral blade 1b2 is provided on the outer side of the rotating shaft 1b1, the first motor 1d can drive the rotating shaft 1b1 to rotate, a liquid outlet hose 3a is provided at the bottom of the liquid storage tank 3, the liquid outlet hose 3a is connected to the metering pump 4, a liquid delivery hose 4a is provided on the metering pump 4, and the liquid delivery hose 4a is connected to the mixing device 2.
[0023] The working principle of this scheme is as follows: Figure 1-3As shown, the raw salt is added into the feeding device 1 from the feeding port 1a, and the rotating shaft 1b1 inside the feeding pipe 1b is driven to rotate by the first motor 1d.
