Description

Technical Field

[0001] The utility model belongs to the technical field of grinding devices, in particular to a grinding device for salt production. Background Art

[0002] Table salt, also known as table salt, is one of the most important substances for human survival and the most commonly used seasoning in cooking. Sodium chloride, the main chemical component of salt, accounts for 99% of table salt (a mixture). Table salt produced in some regions adds potassium chloride to reduce the sodium chloride content to reduce the incidence of hypertension. At the same time, table salt in most parts of the world is added with iodine to prevent iodine deficiency. Table salt with added iodine is called iodized salt. During salt production, coarse salt often needs to be crushed and ground into fine salt for human consumption. When the existing seasoning powder grinder is feeding, the salt powder will be blown up due to the impact of feeding and bagging. The blown up salt powder not only causes waste, but also affects the production environment.

[0003] Publication number CN218222833U is a Chinese utility model patent, which discloses a grinding device for salt production. By setting a rubber sleeve, the rubber sleeve can be extended into the packaging bag to extend the discharge port, thereby preventing the salt powder from being directly exposed to the outside air when being discharged and bagged. In this way, the salt powder can be prevented from being lifted into the air and floating away when being discharged. At the same time, the limit plate in the discharge pipe can block the salt powder when it is discharged, so as to reduce the discharge speed of the salt powder, thereby reducing the impact of the salt powder discharge and alleviating the degree of salt powder lifting, and the two groups The clamping block can clamp and fix the two sides of the bag opening of the packaging bag on the upper side of the baffle, so that the bag opening can be well contracted and put on the baffle, which can ensure that the bag opening will not open excessively during the discharge process, thereby reducing dust and making it convenient for the packaging bag to remain connected to the discharge pipe, avoiding the bag opening being misaligned with the discharge pipe due to the collapse and displacement of the packaging bag, causing salt to spill. However, the device still has some other problems. For example, the device cannot observe the coarseness of the salt grinding in real time, and thus cannot accurately grasp the grinding and crushing progress of the salt. Utility Model Content

[0043] The cylinder 190 is fixedly disposed on the lower surface of the bracket 120, and the output shaft of the cylinder 190 passes through the base and is fixedly connected to the support plate 150;

[0044] An observation window 160 is provided on one side of the grinding jar 100 , and the position of the observation window 160 corresponds to the support plate 150 .

[0045] The grinding mechanism 200 is driven by the driving mechanism 300 to rotate, and the salt is placed between the support plate 150 and the grinding mechanism 200, and the salt is continuously fed into the grinding mechanism 200 and the grinding mechanism 200 is driven by the driving mechanism 300 to rotate.

[0053] The rotating shaft 210 is disposed at the exact center of the upper surface of the supporting plate 150;

[0054] The connecting cylinder 220 is mounted on the rotating shaft 210;

[0055] The grinding disc 230 is fixedly disposed on one side of the connecting tube 220;

[0056] The grinding disc 230 is arranged in a sector shape, and the diameter of the grinding disc 230 is the same as the diameter of the grinding area 151 , and the sector angle of the grinding disc 230 is smaller than the sector angle of the grinding area 151 .

[0057] In the present technical solution, in order to facilitate the grinding of table salt, a grinding mechanism 200 is provided above the support disk 150. The rotating shaft 210 of the grinding mechanism 200 is arranged at the center of the upper surface of the support disk 150. The driving mechanism 300 is fixed to the top of the grinding tank 100. The output shaft of the driving mechanism 300 is fixedly connected to the top of the rotating shaft 210, so that the driving mechanism 300 can drive the rotating shaft 210 to rotate.

In this way, even when the ground granular salt is blocked from the discharge hole 154, the longer and harder bristles 250 can be used to dredge the discharge hole 154, and the air can be controlled. The cylinder 190 drives the support plate 150 to change its height upward, so that the bristles 250 squeeze the discharge hole 154, and the salt stuck inside the discharge hole 154 falls into the base. The two connecting plates 240 are respectively arranged on both sides of the grinding disc 230, and the fan-shaped angle formed by the two connecting plates 240 and the grinding disc 230 is the same as the fan-shaped angle of the grinding area 151.
