Description

Technical Field

[0001] This utility model relates to an automatic feeding device, and more specifically, to an automatic feeding and mixing system for inorganic salts. Background Technology

[0002] Sodium metabisulfite is a chemical raw material with strong reducing properties. During storage, it is prone to absorbing moisture and oxidation, leading to caking and affecting product quality, which is detrimental to sales and use. To address these issues, our company has developed an inorganic salt anti-caking agent. By adding it to sodium metabisulfite in a measured ratio, it helps prevent caking.

[0003] In current production, due to the large volume of the sodium metabisulfite storage silo and the high position of the feed inlet, the inorganic salt anti-caking agent bag needs to be hoisted and transported to a high position for addition, which is inconvenient to operate. In addition, each time it is added, manual operation of equipment is required to move the bag for addition. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a simple and automated inorganic salt feeding and mixing system.

[0005] The technical solution of this utility model is implemented as follows: an automatic feeding and mixing system for inorganic salts includes a storage silo for storing sodium metabisulfite, the lower end of the discharge valve of the storage silo is connected to a mixing silo via a conveying pipe; an inorganic salt feeding silo is provided on one side of the storage silo, and the bottom of the inorganic salt feeding silo is connected to the conveying pipe via a pneumatic conveying pipe, and a quantitative feeder is provided on the pneumatic conveying pipe; an inorganic salt preparation silo is provided on the ground below one side of the inorganic salt feeding silo, and a vacuum feeding assembly is provided between the inorganic salt preparation silo and the inorganic salt feeding silo.

[0006] In the aforementioned automatic inorganic salt feeding and mixing system, a narrowing hopper is provided between the inorganic salt feeding bin and the pneumatic conveying pipe, a deceleration feeding unit is provided inside the narrowing hopper, and a material receiving unit is provided inside the inorganic salt feeding bin.

[0007] In the aforementioned automatic inorganic salt feeding and mixing system, the material receiving unit includes several first inclined plates evenly distributed vertically on the inner wall below the inlet of the inorganic salt feeding hopper, and several second inclined plates evenly distributed on the inner wall of the inorganic salt feeding hopper on the opposite side of the first inclined plates, which are staggered with the first inclined plates. The included angle α between the first and second inclined plates and the inner wall of the inorganic salt feeding hopper is 40-55°.

[0008] In the aforementioned automatic inorganic salt feeding and mixing system, the deceleration feeding unit includes a material distribution block disposed within a narrow-diameter hopper. The discharge end of the narrow-diameter hopper is divided into at least two discharge ports with a diameter smaller than that of the pneumatic conveying pipe by the material distribution block.

[0009] In the aforementioned automatic inorganic salt feeding and mixing system, a vibration motor is installed on the lower outer wall of the inorganic salt feeding hopper.

[0010] With the above-described structure, the inorganic salt anti-caking agent is added to the inorganic salt preparation silo below for storage. When the inorganic salt anti-caking agent in the inorganic salt preparation silo is insufficient, it is automatically replenished by the vacuum feeding component, which can reduce the frequency of handling the material bag. Furthermore, since the inorganic salt preparation silo is located at a lower position, the material bag needs to be hoisted a shorter distance, making it convenient to add.

[0017] See Figure 1-4As shown, this utility model discloses an automatic inorganic salt feeding and mixing system, comprising a storage silo 1 for storing sodium metabisulfite. The lower end of the discharge valve of the storage silo 1 is connected to a mixing silo 3 via a conveying pipe 2. An inorganic salt feeding silo 4 is located on one side of the storage silo 1, and its bottom is connected to the conveying pipe 2 via a pneumatic conveying pipe 5. A quantitative feeder 6 is installed on the pneumatic conveying pipe 5. An inorganic salt preparation silo 7 is located on the ground below the inorganic salt feeding silo 4, and a vacuum feeding assembly 8 is located between the preparation silo 7 and the feeding silo 4. The storage silo controls the conveying rate of sodium metabisulfite by opening and closing the discharge valve. The feeding rate of the quantitative feeder is adjusted according to data such as the diameter of the conveying pipe and the pneumatic conveying pipe, and the conveying rate of the pneumatic conveying pipe, to achieve a suitable feeding ratio of inorganic salt and sodium metabisulfite. The calculation of these parameters and the specific structure of the quantitative feeder are existing technologies and are common knowledge to those skilled in the art, and will not be elaborated further here.

[0018] A sensor is installed in the inorganic salt feeding hopper to detect the inorganic salt level. When the level drops to the lower limit of the hopper, the vacuum feeding assembly automatically feeds the salt. When the level reaches the upper limit, the vacuum feeding assembly stops feeding. The vacuum feeding assembly includes a vacuum feeder, an air pump, and other equipment. The specific connection method is existing technology and common knowledge to those skilled in the art, and will not be described in detail here.

[0019] The inorganic salt anti-caking agent is added to the inorganic salt preparation silo below for storage. When the inorganic salt anti-caking agent in the inorganic salt preparation silo is insufficient, it is automatically replenished by the vacuum feeding component, which can reduce the frequency of handling the material bag. Furthermore, since the inorganic salt preparation silo is set at a low position, the material bag needs to be lifted a short distance, making it convenient to add.

[0020] In this embodiment, a reducing hopper 9 is provided between the inorganic salt feeding bin 4 and the pneumatic conveying pipe 5. A deceleration feeding unit 10 is installed inside the reducing hopper 9, and a receiving unit 11 is installed inside the inorganic salt feeding bin 4. The deceleration feeding unit reduces the amount of inorganic salt fed in a single operation, preventing a large amount of inorganic salt from entering the pneumatic conveying pipe simultaneously, which would result in a heavy load of inorganic salt in the pneumatic conveying pipe that is difficult to blow. Simultaneously, the receiving unit supports the inorganic salt in the feeding bin, preventing excessive stress on the bottom of the feeding bin from causing caking.

[0021] In this embodiment, the material receiving unit 11 includes several first inclined plates 11a evenly distributed vertically on the inner wall below the inlet of the inorganic salt feeding hopper 4, and several second inclined plates 11b evenly distributed on the inner wall of the inorganic salt feeding hopper 4 on the side opposite to the first inclined plates 11a, which are staggered with the first inclined plates 11a. The angle α between the first and second inclined plates 11a and the inner wall of the inorganic salt feeding hopper 4 is 40-55°. By having the staggered first and second inclined plates sequentially receive inorganic salt at different heights, the overall weight is evenly distributed, which can effectively reduce the pressure on the inorganic salt at the bottom and prevent clumping from affecting the feeding. Furthermore, the inclination angle of the first and second inclined plates is set at 40-55° to ensure smooth feeding while bearing the weight of the inorganic salt above, and to prevent the inorganic salt from accumulating on the first and second inclined plates.

[0022] In this embodiment, the deceleration feeding unit 10 includes a distribution block 10a disposed within the reduced-diameter hopper 9. The discharge end of the reduced-diameter hopper 9 is divided into at least two discharge ports 10b with a diameter smaller than that of the pneumatic conveying pipe 5 by the distribution block 10a. The use of discharge ports with diameters smaller than those of the pneumatic conveying pipe ensures that the amount of inorganic salt entering the pneumatic conveying pipe each time does not instantly fill the pipe, effectively preventing blockages and ensuring smooth pneumatic conveying.

[0023] In this embodiment, a vibration motor 12 is provided on the lower outer wall of the inorganic salt feeding bin 4. By setting the vibration motor to vibrate the inorganic salt feeding bin, it is possible to further ensure the smooth feeding of inorganic salt in the inorganic salt feeding bin and avoid clogging the outlet of the inorganic salt feeding bin.

[0024] During operation, the inorganic salt anti-caking agent is added to the inorganic salt preparation silo below for storage. When the inorganic salt anti-caking agent in the silo is insufficient, it is automatically replenished via a vacuum feeding component. The discharge valve of the storage silo is opened to deliver sodium metabisulfite into the conveying pipe. Simultaneously, the quantitative feeder is started to convey the inorganic salt anti-caking agent from the inorganic salt preparation silo into the conveying pipe, where it is mixed with the sodium metabisulfite and then transferred to the mixing silo for further mixing and storage, awaiting packaging.

[0025] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
