Description

Technical Field

[0001] The utility model relates to the technical field of mixing devices, in particular to a mixing device with a quantitative proportioning function. Background Art

[0002] In the chemical industry, mixing devices are often used to prepare the stock solution of some chemical raw materials. However, for chemical raw materials that are prone to hydrolysis, such as carbonamide, ammonium bicarbonate, ammonium chloride, ammonium sulfate, ammonium nitrate, etc., mixing barrels are usually required to process and mix multiple groups of solid and liquid raw materials.

[0003] At present, when performing processing and mixing work, users usually use a mixing barrel for processing. The user puts all the solid and liquid raw materials into the mixing barrel, and then starts the motor to work. The rotation of the motor output shaft drives the multiple groups of stirring blades on the side wall to rotate to process and mix the multiple groups of raw materials inside the mixing barrel.

[0004] However, the mixing structure can only stir the raw materials inside it, but the raw materials will be adsorbed on the inner wall of the mixing device when the mixing device is working, and the adsorbed raw materials are difficult to discharge during the raw material discharge process, which will cause the raw materials to be adsorbed in the mixing device and affect the next use of the mixing device; in view of this, we propose a mixing device with a quantitative proportioning function.

A reciprocating screw 33 is installed, and multiple groups of U-shaped frames 34 are slidably connected on both sides of the inner wall of the mixing box 1. A sleeve 35 is threadedly connected to the surface of the reciprocating screw 33, and one end of a connecting block 36 is fixedly installed on both sides of the sleeve 35. The other end of the connecting block 36 is fixedly connected to a group of side walls of the U-shaped frame 34. A slot 37 is opened on the side wall of the U-shaped frame 34, and one end of a return spring 38 is fixedly installed on the inner wall of the slot 37. A slide plate 39 is fixedly installed on the other end of the return spring 38. A scraper 310 is fixedly installed on the side wall of the slide plate 39. A crushing structure 4 is arranged inside the mixing box 1.

[0024] Specifically, the cleaning structure 3 of the technical solution of the utility model includes: a metering pump 31, a feed hopper 32, a reciprocating screw 33, a U-shaped frame 34, a sleeve 35, a connecting block 36, a notch 37, a return spring 38, a slide plate 39, and a scraper 310.

[0025] In one embodiment of the utility model, a cleaning structure 3 is provided to facilitate cleaning of the inner wall of the mixing box 1. The mixing box 1 is provided for placing and processing raw materials. When adding raw materials, the user can first add the ingredients into the feed hopper 32, and then turn on the metering pump 31. At this time, the ingredients enter the mixing box 1 through the metering pump 31, and the metering pump 31 is used to quantitatively add the amount of ingredients, thereby improving the use effect of the device. There is no need to add raw materials in advance, and the proportion can be determined according to the added raw materials.

[0026] Then the motor 2 can be started to work. The model of the motor 2 is HG-JR353BK. The motor 2 provides power for the rotation of the shaft 5. The output shaft of the motor 2 drives the shaft 5 to rotate. The rotation of the shaft 5 drives the multiple groups of stirring blades 6 on the side wall to rotate and stir, thereby accelerating the mixing of the various raw materials inside the mixing box 1.

[0027] And after the subsequent processing is completed, the motor 2 is still started to work, and the rotation of the rotating shaft 5 drives the reciprocating screw 33 on its surface to rotate, and the rotation of the reciprocating screw 33 drives the sleeve 35 and the connecting block 36 threaded on its surface to move up and down, and the movement of the connecting block 36 drives the U-shaped frame 34 to move. At this time, the scraper 310 on the side wall of the U-shaped frame 34 scrapes the remaining raw materials on the inner wall of the mixing box 1, and moves through the uppermost U-shaped frame 34, and then drives the multiple groups of U-shaped frames 34 below it to move through the fixed rod 7.

[0028] When the scraper 310 moves, the arc-shaped contact block 10 on its side wall will intermittently contact the arc-shaped impact block 9 on the inner wall of the chute 8. After the arc-shaped contact block 10 contacts the arc-shaped impact block 9, it can move outward. The arc-shaped contact block 10 and the scraper 310 move outward and squeeze the slide plate 39 and the return spring 38, so that the scraper 310 is temporarily separated from the inner wall surface of the mixing box 1, so that the pet food accumulated on the upper end of the scraper 310 falls off, further improving the practicality of the device.

[0029] By setting up a crushing structure 4, it is convenient to break up some raw materials piled together in the mixing box 1. The movement of the U-shaped frame 34 drives the connecting rod 43 at its lower end to move. The movement of the connecting rod 43 drives the moving plate 41 and two groups of crushing rollers 42 hinged thereto to move and contact, so as to break up the block raw materials, thereby avoiding the block raw materials taking a long time to mix naturally with the liquid, thereby improving the use efficiency of the device.

[0030] Please continue reading Figure 1-Figure 5The crushing structure 4 includes a movable plate 41 slidably connected to both sides of the inner wall of the mixing box 1, and a crushing roller 42 is arranged on the side wall of the movable plate 41. One end of a connecting rod 43 is hinged at the upper end of the movable plate 41, and the other end of the connecting rod 43 is hinged to the lower end of a group of U-shaped frames 34. The multiple groups of U-shaped frames 34 are fixedly connected by a fixing rod 7. Slide grooves 8 are provided on both sides of the inner wall of the mixing box 1, and an arc-shaped impact block 9 is fixedly installed on the inner wall of the slide groove 8. An arc-shaped contact block 10 is fixedly installed on the side wall of the scraper 310. The scraper 310 is arranged in an arc structure. Multiple groups of return springs 38 are provided, and the multiple groups of return springs 38 are fixedly installed on the inner wall of the slot 37.

[0031] During operation, the user first adds the ingredients into the feed hopper 32, and then turns on the metering pump 31. At this time, the ingredients enter the mixing box 1 through the metering pump 31, so that the metering pump 31 adds the amount of ingredients in a quantitative manner, and then starts the motor 2 to drive the rotating shaft 5 to rotate, and the rotation of the rotating shaft 5 drives the multiple groups of stirring blades 6 on the side wall to rotate and stir. After the subsequent processing is completed, the motor 2 is still started to work, and the rotation of the rotating shaft 5 drives the reciprocating screw 33 to rotate, and the rotation of the reciprocating screw 33 drives the sleeve 35 and the connecting block 36 to move up and down, and the movement of the connecting block 36 drives the U-shaped frame 34 to move. At this time, the scraper 310 on the side wall of the U-shaped frame 34 scrapes off the remaining raw materials on the inner wall of the mixing box 1, and moves through the uppermost U-shaped frame 34, and then The fixed rod 7 drives the multiple groups of U-shaped frames 34 below it to move. When the scraper 310 moves, the arc-shaped contact block 10 on its side wall will intermittently contact the arc-shaped impact block 9 on the inner wall of the slide 8. When the arc-shaped contact block 10 contacts the arc-shaped impact block 9, it can move outward. The arc-shaped contact block 10 and the scraper 310 move outward and squeeze the slide plate 39 and the return spring 38, so that the scraper 310 is temporarily separated from the inner wall surface of the mixing box 1, so that the pet food accumulated on the upper end of the scraper 310 falls off, and the movement of the U-shaped frame 34 drives the connecting rod 43 at its lower end to move. The movement of the connecting rod 43 drives the moving plate 41 and the two groups of crushing rollers 42 hinged thereto to move and contact, so as to break the block raw materials, thereby improving the use efficiency of the device.

[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
