Description

Technical Field

[0001] This solution belongs to the field of V-type air classifiers, specifically involving a uniformly mixed V-type air classifier. Background Technology

[0002] In the field of material sorting, the V-type air separator is a common airflow separation device, widely used in industries such as waste treatment, recycling, and food processing. Its core principle is to separate materials of different weights by utilizing differences in airflow velocity.

[0003] A search revealed a utility model patent with authorization announcement number CN207325041U, which discloses a V-type air classifier, including an air classifier chamber, an air inlet chamber, and an air outlet chamber. The air classifier chamber has a feed inlet at the top and a coarse material outlet at the bottom. An air inlet guide plate is provided between the air inlet chamber and the air classifier chamber, and the inclination of each air inlet guide plate gradually increases from top to bottom. The feed inlet is located above the uppermost air inlet guide plate, which is connected to a vibrator. An air distribution plate is provided between the air inlet chamber and the air inlet guide plate, and at least two inclined air outlet guide plates are arranged in a stepped manner between the air outlet chamber and the air classifier chamber.

[0004] In existing technologies, traditional V-type air classifiers typically use a free-fall feeding method at the feed inlet. However, when feeding wet materials, the material is prone to accumulating and sticking at the feed inlet, leading to poor feeding or blockage. In addition, uneven feeding directly affects the air classification efficiency, resulting in incomplete mixing and separation of light and heavy materials, thus reducing the classification accuracy. Utility Model Content

[0005] The purpose of this solution is to provide a uniformly mixed V-type air classifier to solve the problem that wet materials easily accumulate and stick at the feed inlet, leading to poor material flow or blockage. It also solves the problem that uneven feeding directly affects the air classification efficiency.

[0006] To achieve the above objectives, this solution provides a uniformly mixed V-type classifier, including a casing. A feed inlet is connected to the top of the casing. A bracket, L-shaped, is fixedly connected to the left side of the inner wall of the feed inlet. A sliding sleeve is slidably fitted onto the outer side of the vertical portion of the bracket. A spring is installed inside the sliding sleeve, with one end fixedly connected to the bracket and the other end fixedly connected to the inner surface of the sliding sleeve. The spring allows the reaction force to be returned to the sliding sleeve, providing auxiliary reset for the sliding sleeve and the branch rods. Multiple branch rods are fixedly connected to the outer side of the sliding sleeve, and a linkage plate is fixedly connected to the outer side of the sliding sleeve. The linkage plate passes through the feed inlet and is slidably connected to it. A motor is fixedly mounted on the outer wall of the feed inlet, and a cam is fixedly connected to the end of the motor's output shaft. The side of the cam abuts against the linkage plate. An air inlet pipe is fixedly connected to the side wall of the feed inlet, and the air inlet pipe passes through the feed inlet. An annular pipe is connected to the end of the air inlet pipe, and a nozzle is installed on the inner wall of the annular pipe.

[0007] The principle of this solution is as follows: When in use, the air inlet pipe is first connected to a pressurized dry air source through a pipeline. This allows dry air to be delivered into the ring pipe and sprayed evenly from the nozzle. As the material passes through the feed inlet and enters the machine casing, it can be pre-dried to avoid excessive humidity that would reduce the sorting accuracy. At the same time, the cam driven by the motor moves the linkage plate and the fork rod back and forth. Then, with the elastic reset of the spring, the material is continuously agitated and dispersed in the feed inlet, preventing accumulation and blockage, and further improving the uniformity of subsequent sorting.

[0008] The technical advantage of this solution is that by setting a sliding sleeve with a forked rod that is elastically supported by a spring inside the feed inlet, and then driving the cam with a motor to drive the linkage plate and the forked rod to reciprocate, and then cooperating with the elastic reset of the spring, the material is continuously moved and dispersed in the feed inlet, avoiding accumulation and blockage, and facilitating uniform subsequent sorting.

[0009] By setting a ring pipe inside the feed inlet, with multiple downward-sloping nozzles arranged in a ring array on the inner ring, and then connecting the air inlet pipe of the ring pipe to pressurized dry air, the material can be dried before sorting.

[0010] Furthermore, the inner wall of the sliding sleeve is provided with ball bearings, which are slidably connected to the circumferential surface of the bracket. The ball bearings reduce the relative friction between the sliding sleeve and the bracket.

[0011] Furthermore, a baffle is fixedly connected to the linkage plate, and the baffle is slidably connected to the inner wall of the feed inlet. A notch is provided on the side wall of the feed inlet to provide lifting space for the linkage plate, while the baffle is used to seal the notch to prevent material from overflowing from the notch.

[0012] Furthermore, the nozzles are provided in multiple ways, and the multiple nozzles are distributed in a ring array along the circumference of the annular tube. The nozzles are inclined downwards to prevent material from overflowing from the feed inlet.

[0013] Furthermore, a flow guide is fixedly connected to the inner side of the upper opening of the feed inlet. The lower opening of the flow guide is narrow, and its position corresponds to the position of the annular tube. The flow guide, in conjunction with the nozzle, further prevents material from overflowing from the feed inlet opening.

[0014] Furthermore, multiple fixing rods are fixedly connected to the outer wall of the annular tube, and the ends of the fixing rods are fixedly connected to the inner wall of the feed inlet. The fixing rods provide auxiliary fixation for the annular tube. Attached Figure Description

Detailed Implementation

[0017] The basic implementation examples are as follows: Figures 1-3 The diagram shows a uniformly mixing V-type air classifier, comprising a casing 1, with a feed inlet 2 connected to the top of the casing 1. A bracket 3, L-shaped, is fixedly connected to the left side of the inner wall of the feed inlet 2. A sliding sleeve 4 is slidably fitted onto the outer side of the vertical part of the bracket 3. Multiple forked rods 5 are fixedly connected to the outer side of the sliding sleeve 4. A spring 6 is installed inside the sliding sleeve 4, with one end fixedly connected to the bracket 3 and the other end fixedly connected to the inner surface of the sliding sleeve 4. The spring 6 allows the reaction force to be returned to the sliding sleeve 4, providing auxiliary reset for the sliding sleeve 4 and the forked rods 5. Ball bearings 7 are installed on the inner wall of the sliding sleeve 4, and the ball bearings 7 are slidably connected to the circumferential surface of the bracket 3. The ball bearings 7 reduce the relative friction between the sliding sleeve 4 and the bracket 3.

[0018] like Figure 3 As shown, a linkage plate 8 is fixedly connected to the outer side of the sliding sleeve 4. The linkage plate 8 passes through the feed inlet 2 and is slidably connected to the feed inlet 2. A motor 9 is fixedly installed on the outer wall of the feed inlet 2. A cam 10 is fixedly connected to the end of the output shaft of the motor 9. The side of the cam 10 abuts against the linkage plate 8. A baffle 11 is fixedly connected to the linkage plate 8 and is slidably connected to the inner wall of the feed inlet 2. A notch is provided on the side wall of the feed inlet 2 to provide lifting space for the linkage plate 8, while the baffle 11 is used to block the notch to prevent material from overflowing from the notch.

[0019] like Figure 3 , Figure 4 As shown, an air inlet pipe 12 is fixedly connected to the side wall of the feed inlet 2, and the air inlet pipe 12 penetrates through the feed inlet 2. An annular pipe 13 is connected to the end of the air inlet pipe 12. Multiple nozzles 14 are arranged in a circular array along the circumference of the annular pipe 13, and the nozzles 14 are angled downwards to prevent material from overflowing from the feed inlet 2. A flow guide shroud 15 is fixedly connected to the inner side of the upper opening of the feed inlet 2. The lower opening of the flow guide shroud 15 is narrow, and its position corresponds to the position of the annular pipe 13. The flow guide shroud 15, in conjunction with the nozzles 14, further prevents material from overflowing from the opening of the feed inlet 2. Multiple fixing rods 16 are fixedly connected to the outer wall of the annular pipe 13, and the ends of the fixing rods 16 are fixedly connected to the inner wall of the feed inlet 2. The fixing rods 16 provide auxiliary fixation for the annular pipe 13.

[0020] The specific implementation process of this utility model is as follows: In use, the air inlet pipe 12 is first connected to a pressurized dry air source through a pipeline. This allows dry air to be delivered into the ring pipe 13 and sprayed evenly from the nozzle 14. In this way, when the material passes through the feed inlet 2 and enters the casing 1, it can be pre-dried to avoid excessive humidity leading to a decrease in sorting accuracy. At the same time, the cam 10 driven by the motor 9 drives the linkage plate 8 and the fork rod 5 to reciprocate. Then, with the elastic reset of the spring 6, the material is continuously agitated and dispersed in the feed inlet 2 to avoid accumulation and blockage, and further improve the uniformity of subsequent sorting.

[0021] This solution involves installing a sliding sleeve 4 with a forked rod 5, elastically supported by a spring 6, inside the feed inlet 2. A cam 10, driven by a motor 9, drives the linkage plate 8 and the forked rod 5 in reciprocating motion. The spring 6 then provides elastic reset, continuously agitating and dispersing the material within the feed inlet 2, preventing accumulation and blockage, and facilitating uniform subsequent sorting. Furthermore, a ring pipe 13 is installed inside the feed inlet 2, with multiple downward-sloping nozzles 14 arranged in a circular array on its inner ring. The air inlet pipe 12 of the ring pipe 13 is connected to pressurized drying air, allowing for pre-sorting drying of the material.
