A stirring mechanism for a liquid feeding device

Abstract

This utility model relates to the field of liquid feeding equipment, and in particular to a stirring mechanism for a liquid feeding device, including a stirring drum, a stirring mechanism, and a crushing mechanism. The stirring drum is arranged inside and outside the device, with a lid inserted into the top. The stirring mechanism is located inside the stirring drum and includes an inner drum stirring blade and a guide blade. The inner drum is rotatably mounted inside the stirring drum via a rotating assembly, and the stirring blade is fixed to the inner wall of the inner drum. The rotating assembly drives the inner drum, stirring blade, and guide blade to rotate, simultaneously stirring the liquid feed and creating an internal and external circulation. The circulating liquid feed is filtered through a filter plate. A rotating roller rotates along with the inner drum, causing several burrs to roll on the filter plate, piercing any clumps.

The crushed clumps are more easily dissolved with other liquid feed, forming a stirring and crushing cycle, thus improving the stirring effect.

Description

Technical Field

[0001] This utility model relates to the field of liquid feeding equipment, and in particular to a stirring mechanism of a liquid feeding device. Background Technology

[0002] According to the patent document with publication number CN220345595U, the patent document describes a method where a drive motor rotates a central column, which in turn drives the first stirring blade to stir the liquid feed material in the mixing tank. During this process, the central column drives the edge column on the drive rod to move in a circular motion around the central column. The edge column then stirs the liquid feed material with the second stirring blade, which is equidistantly arranged in the vertical direction. The central gear fixed at the bottom of the support frame meshes with the driven gear, so that while the edge column moves in a circular motion around the central column, it also rotates around its own axis, thus performing compound stirring of the liquid feed material.

[0003] The patent document states that during the mixing process of liquid feed ingredients and water, air bubbles in the water adhere to the surface of the liquid feed ingredient particles, forming an air film that hinders the full contact between the liquid feed ingredient particles and water, leading to clumping. The clumped mixture dissolves slowly, affecting the mixing effect. Utility Model Content

[0004] The purpose of this invention is to provide a stirring mechanism for a liquid feeding device in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A stirring mechanism for a liquid feeding device includes a stirring drum, a stirring mechanism, and a crushing mechanism.

[0007] The mixing drum has an inner and outer part, and a lid is inserted into the top of the mixing drum.

[0008] The stirring mechanism is located inside the stirring drum. The stirring mechanism includes an inner drum stirring blade and a guide blade. The inner drum is rotatably installed inside the stirring drum via a rotating assembly. The stirring blade is fixed on the inner side wall of the inner drum, and the guide blade is fixed on the outer side wall of the inner drum.

[0009] The crushing mechanism is located between the inner cylinder and the mixing cylinder. The crushing mechanism includes a filter plate, a rotating roller and several burrs. The filter plate is fixed on the inner wall of the mixing cylinder and is located below the guide vane. The rotating roller is rotatably connected to the outer wall of the inner cylinder. The rotating roller is driven by the drive assembly to rotate with the inner cylinder while rotating itself. Several burrs are fixed at equal intervals on the outer wall of the rotating roller.

[0010] Preferably, the rotating assembly includes an upper rotating frame and a lower rotating frame. The upper rotating frame is rotatably connected to the bottom of the cylinder cover, and the lower rotating frame is rotatably connected to the bottom of the inner side of the mixing cylinder. The inner cylinder is fixed between the upper rotating frame and the lower rotating frame. The input end of the upper rotating frame is splinedly connected to a motor, and the motor is fixed to the top of the cylinder cover.

[0011] Preferably, the upper and lower rotating frames have the same structure, and both the upper and lower rotating frames have a trough for the flow of liquid feed raw materials at the end near the inner cylinder.

[0012] Preferably, the stirring blade and the guide blade are oriented in opposite directions, with the guide blade located on the outer side of the top of the stirring blade.

[0013] Preferably, the drive assembly includes a gear and a rack. The gear is fixed to one end of the roller near the mixing drum, and the rack is annular and fixed to the inner wall of the mixing drum. The gear meshes with the top of the rack.

[0015] Preferably, a feed pipe is fixed to the top of the cylinder cover, and a discharge pipe is fixed to the bottom of the mixing cylinder.

[0016] The beneficial effects compared with the existing technology are as follows: The rotating component drives the inner cylinder, stirring blades and guide blades to rotate, which stirs the liquid feed and forms an internal and external circulation. The circulating liquid feed is filtered by the filter plate. The rotating roller rotates with the inner cylinder and rotates itself, which in turn drives several burrs to roll on the filter plate to puncture the clumps. The burrs bounce back and throw off the liquid feed adhering to them. The broken clumps are more easily dissolved with other liquid feed, forming a stirring and breaking cycle, which improves the stirring effect. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1-6 As shown, a mixing mechanism of a liquid feeding device includes a mixing drum 1, a mixing mechanism, and a crushing mechanism. The mixing drum 1 is arranged inside and outside. A drum cover 2 is inserted into the top of the mixing drum 1. A feed pipe 3 is fixed to the top of the drum cover 2. A discharge pipe 4 is fixed to the bottom of the mixing drum 1. Water and liquid feed raw materials are put into the inner drum 503 through the feed pipe 3. The mixed liquid feed in the mixing drum 1 is discharged by opening the valve of the discharge pipe 4. The inside of the mixing drum 1 can be cleaned by pulling up the drum cover 2 and the motor 504.

[0029] The stirring mechanism is located inside the stirring drum 1. The stirring mechanism includes an inner drum 503, stirring blades 505, and guide blades 506. The inner drum 503 is rotatably mounted inside the stirring drum 1 via a rotating assembly. The stirring blades 505 are fixed to the inner wall of the inner drum 503, and the guide blades 506 are fixed to the outer wall of the inner drum 503. The stirring blades 505 and guide blades 506 are in opposite directions, with the guide blades 506 located on the outer side of the top of the stirring blades 505. The rotating assembly includes an upper rotating frame 501 and a lower rotating frame 502. The upper rotating frame 501 is rotatably connected to the bottom of the drum cover 2, and the lower rotating frame 502 is rotatably connected to the bottom of the inner side of the stirring drum 1. The inner drum 503 is fixed between the upper rotating frame 501 and the lower rotating frame 502. A motor 504 is splinedly connected to the input end of the upper rotating frame 501. The motor 504 is fixed to the top of the drum cover 2. The upper rotating frame 501 and the lower rotating frame 502 have the same structure. Both the upper rotating frame 501 and the lower rotating frame 502 have grooves for the flow of liquid feed raw materials at one end near the inner cylinder 503. The upper rotating frame 501 is driven to rotate by the motor 504, which in turn drives the lower rotating frame 502 and the inner cylinder 503 to rotate, thereby driving the stirring blade 505 and the guide blade 506 to rotate. The rotation of the stirring blade 505 drives the water and liquid feed raw materials to move upward and stir at the same time. The liquid feed moves upward and flows out of the groove of the upper rotating frame 501 and enters the guide blade 506. The rotation of the guide blade 506 drives the liquid feed to move downward and fall. The liquid feed processed by the crushing mechanism is sucked into the inner cylinder 503 by the stirring blade 505 through the groove of the lower rotating frame 502, forming a stirring and crushing cycle, which improves the stirring effect.

[0030] The crushing mechanism is located between the inner cylinder 503 and the mixing drum 1. The crushing mechanism includes a filter plate 601, a rotating roller 602, and several burrs 603. The filter plate 601 is fixed to the inner wall of the mixing drum 1 and is located below the guide vane 506. The rotating roller 602 is rotatably connected to the outer wall of the inner cylinder 503. The rotating roller 602 rotates along with the inner cylinder 503 via a drive assembly, and the burrs 603 are equidistantly fixed to the outer side of the rotating roller 602. On the side wall, the burrs 603 are made of elastic material, and the length of the burrs 603 is greater than the distance between the bottom of the rotating roller 602 and the filter plate 601. The drive assembly includes a gear 604 and a rack 605. The gear 604 is fixed to one end of the rotating roller 602 near the mixing drum 1, and the rack 605 is annular and fixed to the inner side wall of the mixing drum 1. The gear 604 meshes with the top of the rack 605. The liquid feed is filtered through the filter plate 601, and the clumps in the liquid feed are removed. The filtered liquid feed, intercepted at the top of the filter plate 601, falls down and, through the rotation of the inner cylinder 503, drives the rotating roller 602 to rotate. Gear 604 and rack 605 mesh, causing gear 604 to roll along rack 605, thus driving the rotating roller 602 to rotate. This causes the rotating roller 602 to rotate simultaneously with the inner cylinder 503, and through the rotating roller 602, several burrs 603 roll on the filter plate 601. Since the length of the burrs 603 is greater than the rotation... The distance between the bottom of roller 602 and filter plate 601 is such that after the burrs 603 puncture the clumps, part of the burrs 603 inserts into the filter holes of filter plate 601 to clear the blockage, while the other part is squeezed by filter plate 601. Roller 602 continues to drive the burrs 603 to rotate without contacting filter plate 601. The burrs 603 bounce back and throw off the liquid feed adhering to them. The broken clumps dissolve with other liquid feed and fall through filter plate 601 with other liquid feed.

[0031] Working principle: Water and liquid feed ingredients are fed into the inner cylinder 503 through the feed pipe 3. The motor 504 drives the upper rotating frame 501 to rotate, which in turn drives the lower rotating frame 502 and the inner cylinder 503 to rotate, thereby driving the stirring blades 505 and guide blades 506 to rotate. The rotation of the stirring blades 505 causes the water and liquid feed ingredients to move upward and be stirred at the same time. The liquid feed moves upward and flows out of the groove of the upper rotating frame 501 and enters the guide blades 506. The rotation of the guide blades 506 causes the liquid feed to move downward and fall through the filter plate 601 to filter the liquid feed. The clumps in the liquid feed are intercepted at the top of the filter plate 601. The rotation of the inner cylinder 503 drives the rotating roller 602 to rotate. The gear 604 and the rack 605 mesh, and the gear 604 rolls along the rack 605. Thus, the gear 604 drives the rotating roller 602 to rotate, so that the rotating roller 602 rotates while the inner cylinder 503 rotates. 2. Several burrs 603 are driven to roll on the filter plate 601. Since the length of the burrs 603 is greater than the distance between the bottom of the roller 602 and the filter plate 601, after the burrs 603 puncture the clumps, some of the burrs 603 insert into the filter holes of the filter plate 601 to clear the blockage, while the other part is squeezed by the filter plate 601. The roller 602 continues to drive the burrs 603 to rotate without contacting the filter plate 601. The burrs 603 bounce back and throw off the liquid feed adhering to them. The clumps after being broken dissolve with other liquid feed and fall through the filter plate 601 with other liquid feed. The liquid feed processed by the crushing mechanism is sucked into the inner cylinder 503 by the stirring blade 505 through the groove of the lower rotating frame 502, forming a stirring and crushing cycle to improve the stirring effect. After the stirring is completed, the stirred liquid feed in the stirring cylinder 1 is discharged by opening the valve of the discharge pipe 4. The cylinder cover 2 and the motor 504 are pulled upwards to facilitate cleaning of the stirring cylinder 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
