Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to a feeding and stirring device on a small sand mill. Background Art

[0002] Sand mills can be used to grind materials in the fields of battery materials, pharmaceuticals, printing, cosmetics, food, coatings, etc. The stirring tank on a small laboratory sand mill is an important component of the sand mill. It can cooperate with the sand mill body to complete the closed cycle of material input and material output, and can mix, stir, and disperse materials. It is a transfer station for achieving continuous material processing. At present, the stirring tank on a small laboratory sand mill has some defects:

[0003] The solid-liquid materials need to be pre-dispersed and mixed before being poured into the mixing tank, which brings additional burden to laboratory staff;

[0004] When increasing the solid content, powder materials need to be manually added into the mixing tank, such as carbon black, graphene, and carbon nanotube powders required for the conductive slurry. This will cause a certain amount of dust pollution, affecting the lung health of workers and causing pollution to surrounding experimental equipment.

[0005] When the slurry fluidity is low, the stirring paddle cannot stir the area far away from the blade, resulting in uneven dispersion of the slurry and affecting subsequent grinding. Utility Model Content

[0006] The purpose of the utility model is to provide a feeding and stirring device for a small sand mill, which effectively solves the problems raised in the above background technology.

[0007] In order to achieve the above-mentioned purpose, the present utility model provides the following technical solutions.

[0009] It can be seen that the setting of the inclined loading tank, plastic hose, and vacuum loading machine can make the powder automatically loaded, reduce the feeding time of the powder, reduce the harm of dust to the human lungs and the pollution to the surrounding environment. Liquid materials can be added through the liquid feed port, which is convenient for adjusting the solid content of the slurry. There is no need to pre-disperse the solid-liquid material, which reduces the burden on laboratory staff. In addition, through the mutual cooperation of the stirring paddle, dispersion plate and motor, the agglomeration of the slurry can be reduced, and with the setting of the lifting mechanism, the dispersion plate can be driven to rise and fall back during the stirring process, thereby solving the problem of uneven mixing in the upper layer of the liquid surface, which is beneficial to the dispersion of the slurry and improves the grinding efficiency.

[0027] See also Figure 1-Figure 4 The present invention provides a feeding and stirring device for a small sand mill, comprising a workbench 100, the upper surface of which is provided with an inclined feeding tank 101 and a stirring tank 102. A plastic hose 103 is connected to the bottom of the inclined feeding tank 101, and a vacuum feeder 104 is provided on one side of the top of the stirring tank 102. The end of the plastic hose 103 is connected to the vacuum feeder 104, and the top of the vacuum feeder 104 is connected to an air intake 105. A liquid feed port is provided on the other side of the top of the stirring tank 102, and a cap 106 is provided on the top of the liquid feed port. A slurry feed port 107 is connected to the side surface of the stirring tank 102, and a discharge port 108 is connected to the bottom of the stirring tank 102. A U-shaped frame 109 is mounted on the top of the mixing tank 102. A motor 110 is mounted on the top of the U-shaped frame 109. A stirring shaft 111 is connected to the end of the output shaft of the motor 110. A sleeve 113 is mounted on the outer surface of the stirring shaft 111 for limited sliding. A stirring paddle 112 is mounted on the bottom of the stirring shaft 111. A dispersion disk 114 is mounted on the outer surface of the sleeve 113. The outer surface of the stirring shaft 111 is provided with a lifting mechanism 200 that can drive the sleeve 113 to rise and fall as the stirring shaft 111 rotates.

[0028] During use, the arrangement of the inclined loading tank 101, the plastic hose 103, and the vacuum loading machine 104 allows automatic loading of powders, reducing the feeding time of the powders, and reducing the harm of dust to the human lungs and the pollution to the surrounding environment. Liquid materials can be added through the liquid feed port, which facilitates the adjustment of the solid content of the slurry, eliminates the need for pre-dispersion of the solid-liquid materials, and reduces the burden on laboratory staff. In addition, the discharge port 108 can be connected to the feed end of the sand mill, and the slurry feed port 107 can be connected to the discharge end of the sand mill, which can achieve the purpose of continuous sand milling cycle of the slurry. By starting the motor 110, its output shaft drives the stirring shaft 111 to rotate, and drives the sleeve 113 on its outer surface to rotate synchronously, so that the stirring paddle 112 and the dispersion disk 114 can stir and break up the slurry, reduce the agglomeration of the slurry, and cooperate with the setting of the lifting mechanism 200 to drive the dispersion disk 114 to rise and fall back during the stirring process, thereby solving the problem of uneven mixing in the upper layer of the liquid surface, which is beneficial to the dispersion of the slurry and improves the grinding efficiency.

[0029] Specifically, the lifting mechanism 200 includes a reciprocating thread 201 provided on the outer surface of the stirring shaft 111, and a driving block 202 is installed on the outer surface of the reciprocating thread 201. The outer surfaces of both sides of the driving block 202 are connected to the limiting plates 203. The ends of the limiting plates 203 are slidingly connected to the inner wall of the U-shaped frame 109. The outer surface of the sleeve 113 is sleeved with a bearing 204. The outer surfaces of both sides of the bearing 204 are installed with connecting plates 205. The ends of the connecting plates 205 are connected to the lower surfaces of the limiting plates 203. Since the driving block 202 is limited by the limiting plate 203, when the motor 110 drives the stirring shaft 111 to rotate, the setting of the reciprocating thread 201 can drive the driving block 202 to reciprocate and lift in the vertical direction, and then through the connection between the connecting plate 205 and the bearing 204, the purpose of driving the sleeve 113 to rotate and reciprocate and lift is achieved, effectively solving the problem of uneven mixing in the upper layer of the liquid surface.

[0030] Specifically, two support frames 300 are installed on the upper surface of the workbench 100, and the upper surfaces of the two support frames 300 are both provided with a card slot 301. The outer surfaces of both sides of the inclined loading tank 101 are both provided with lugs 302, and the lugs 302 are arranged in the card slot 301. Through the setting of the support frames 300, the inclined loading tank 101 can be supported, and through the setting of the card slot 301 and the lug 302, the inclined loading tank 101 can be easily disassembled for maintenance or cleaning.

[0031] Specifically, an observation window 400 is provided on the upper surface of the cap 106 , and the state of the slurry can be easily observed through the setting of the observation window 400 .

[0032] Specifically, the vacuum loader 104 and the stirring tank 102 are connected via a flange. The flange connection method not only ensures the reliability of the connection between the vacuum loader 104 and the stirring tank 102 and the sealing effect of the connection, but also facilitates subsequent disassembly and cleaning.

[0033] Specifically, there are four dispersion discs 114 , and the four dispersion discs 114 are equidistantly distributed. During the lifting process, the path length of the four dispersion discs 114 is consistent with the distance between two adjacent dispersion discs 114 , thereby expanding the stirring range and improving uniformity.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
