Description

Technical Field

[0001] The utility model belongs to the technical field related to calcium lactate production, in particular to raw material feeding equipment for crushing and screening calcium lactate. Background Art

[0002] Calcium lactate is an organic compound, commonly used as a calcium supplement, which has the functions of promoting the calcification of bones and teeth, maintaining the normal excitability of nerves and muscles, and reducing the permeability of capillaries. Its molecular formula is C6H10CaO6, and it is white or milky white crystalline powder. It is easily soluble in hot water, insoluble in ethanol, chloroform and ether. The use of calcium lactate is that calcium lactate is mainly used to prevent and treat calcium deficiency, such as osteoporosis, tetany, bone dysplasia, rickets, and calcium supplementation for children, pregnant and lactating women, menopausal women, and the elderly. In addition, calcium lactate can also be used as a food additive, a fortifier for children's nutritional food, and for calcium supplementation in medicine. In order to ensure the fineness of the calcium lactate powder used after production, the powder needs to be sieved. During sieving, the calcium lactate powder needs to be fed to the sieving equipment through the feeding equipment for sieving, but it still has the following disadvantages in actual use:

[0003] When calcium lactate is crushed and screened and fed into the screening device, the raw materials are directly fed into the hopper. During the transportation process, the dust generated on the powder is large, which will spread into the working environment and cause safety hazards. Therefore, the dust is separated in time when feeding through the flexible plate. However, when it is opened, some dust will still diffuse out, and the effect of preventing dust is not good enough;

[0004] When calcium lactate is crushed, screened and fed into the raw materials, the raw materials are directly fed into the screening component. When the screening area of ​​the screening structure is large, the laying area of ​​the calcium lactate powder is limited, which affects the screening efficiency. Utility Model Content

[0005] The utility model aims to provide a raw material feeding device for crushing and screening calcium lactate. By arranging a feeding component, a discharge port, an air jet port and a driving component, the utility model solves the problems that the effect of preventing dust from being raised when crushing and screening the raw material for feeding calcium lactate is not good enough and the paving area of ​​calcium lactate powder is limited, which affects the screening efficiency.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a raw material feeding device for crushing and screening calcium lactate, comprising a feeding component, a discharge port, an air jet and a driving component. The upper parts of both sides of the feeding component are both penetrated and fixed with air jets, and the two air jets are symmetrical with each other. Flexible inclined plates are symmetrically fixed on the inner wall of the feeding component above the air jets, and the lower parts of the two flexible inclined plates abut against each other. The bottom of the feeding component is fixed with a discharge port, and the lower part of the feeding component is rotatably connected with a driving component. When working, the calcium lactate material is transferred by the feeding component, the calcium lactate powder in the feeding component is output through the discharge port, high-pressure air is sprayed in through the air jet, and the calcium lactate powder in the lower part of the feeding component is stirred by the driving component, so that the calcium lactate powder is more convenient to be input from the feeding component to the discharge port.

[0008] Furthermore, the bottom of the feeding component is arranged in an arc shape, and a discharge opening is provided in the middle of the bottom, and a plug hole is provided at the lower part of one end of the feeding component, and the feeding component outputs the material therein to the discharge port through the discharge opening.

[0009] Furthermore, fixed openings are provided on both sides of the feeding assembly, and a feeding hopper is fixedly connected to the top of the feeding assembly. The feeding assembly fixes the air jet through the fixed opening, and the calcium lactate powder is concentrated into the feeding assembly through the feeding hopper.

[0010] Furthermore, flexible connecting strips are symmetrically fixed on the inner walls of the two end surfaces of the discharge port, and an elastic plate is fixed at the bottom of the flexible connecting strip. The elastic plate is symmetrically arranged along the longitudinal center line of the bottom of the discharge port in a top view, and the discharge port is connected to the elastic plate through the flexible connecting strip.

[0011] Furthermore, the jet port is fixed in the fixed port, and a side of the jet port away from the feeding assembly is evenly fixedly connected with an air pipe along the transverse center line. The jet port transports high-pressure air to the jet port through the air pipe and sprays it into the feeding assembly through the jet port.

[0012] Furthermore, the driving assembly includes a driving motor, a driving shaft, a rotating shaft and a rotating block. The driving shaft is fixed to the output end of the driving motor, and the rotating shaft is fixed to the end of the driving shaft away from the driving motor. The rotating shaft is inserted into the socket, and the end of the rotating shaft away from the driving shaft is rotatably connected to the inner wall of the feeding assembly. Rotating blocks are evenly fixed on the circumference of the rotating shaft. The driving motor drives the output shaft to drive the rotating shaft to rotate, so that the rotating block rotates. During the rotation of the rotating block, the calcium lactate powder in the lower part of the feeding assembly is stirred.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem of insufficient dust prevention effect when raw materials are fed through crushing, screening and feeding of calcium lactate by arranging a feeding component and an air jet port. The utility model conveys the calcium lactate powder into a feeding hopper, centrally conveys it to the feeding component through the feeding hopper, and then falls to the lower inner part of the feeding component through the feeding component. The flexible inclined plate is opened when the calcium lactate powder is conveyed into the feeding component, so that the calcium lactate powder falls to the lower inner part of the feeding component, and is closed when the conveying is stopped, so that the inner cavity of the feeding component below is sealed. At the same time, high-pressure air is conveyed into the air jet port through an air conveying pipe, and then conveyed to the feeding component through the air jet port. The air jet port is arranged obliquely to generate negative pressure on the upper part of the feeding component, so that dust is better prevented in the production process of calcium lactate powder.

[0015] The utility model solves the problem that the paving area of ​​calcium lactate powder is limited and affects the screening efficiency when calcium lactate is crushed, screened and fed into raw materials by arranging a feeding component, a discharging port and a driving component. When the calcium lactate powder falls into the lower part of the feeding component, the driving component is started so that the calcium lactate powder is stirred and smoothly falls into the discharging opening, and then falls into the discharging port in the discharging opening. The discharging port is connected to the elastic plate through a flexible connecting strip. When the calcium lactate powder falls, it falls onto the elastic plate through the elastic plate, and the calcium lactate powder is bounced and dispersed into the screening equipment. When the calcium lactate powder is crushed, screened and fed into raw materials, the paving area of ​​the calcium lactate powder is larger and the screening efficiency is higher.
