Description

Technical Field

[0001] This utility model relates to the technical field of V-type air classifiers, specifically an adjustable V-type air classifier. Background Technology

[0002] With the development of material grinding technology, roller presses have been widely used. The roller press grinding system, which combines roller presses and classifiers, is a highly efficient and energy-saving grinding system with a very broad application prospect in the mineral grinding production industry. The V-shaped classifier, which integrates drying, dispersing and grading and is matched with roller presses, has also been developed and widely used. The interior of the V-classifier is composed of stepped guide plates, which disperse the material and the airflow selects out the fine powder through the gaps between the guide plates.

[0003] Due to its inherent structure, the feed inlet of the V-type classifier is flat and elongated. After being squeezed by the roller press, the material fed into the V-type classifier is columnar and overly concentrated on one side of the feed inlet due to the direction of material flow and inertia. This results in the inability to select fine powder from the material layer, which seriously affects the classification efficiency of the V-type classifier. Qualified fine powder cannot be selected in time and is subsequently returned to the roller press for further extrusion along with coarse particles. The mixing of coarse and fine materials is more prone to segregation when entering the roller press. Therefore, an adjustable V-type classifier is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable V-type air classifier to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable V-type air classifier includes a V-type air classifier body, a discharge chute, and a feed pipe. A mounting frame is provided on one side of the V-type air classifier body. A mounting plate is fixedly connected to the top of the mounting frame. A first positioning block is fixedly connected to the top of the mounting plate. A first connecting block is rotatably connected to the outer side of the first positioning block via a rotating shaft. A hydraulic cylinder is mounted on the outer side of the first connecting block. A second connecting block is fixedly connected to the end of the output shaft of the hydraulic cylinder. A second positioning block is rotatably connected to the outer side of the second connecting block via a rotating shaft. The second positioning block is fixedly connected to the discharge chute. A third positioning block is fixedly connected to the upper surface of the mounting plate. A third connecting block is rotatably connected to the outer side of the third positioning block via a rotating shaft. A telescopic rod is fixedly connected to the outer side of the third connecting block. A fourth connecting block is fixedly connected to the end of the telescopic rod away from the third connecting block. A connecting shaft is rotatably connected to the outer side of the fourth connecting block via a rotating shaft. A mounting block is fixedly connected to the end of the connecting shaft away from the fourth connecting block. A spring is fixedly connected to the side of the mounting block where the connecting shaft is located. A pressure sensor body is installed at the other end of the spring. A controller that can control the hydraulic cylinder is installed on the upper surface of the mounting plate. Rubber hoses are detachably connected to both ends of the discharge chute via flanges.

[0007] Preferably, the controller is electrically connected to the pressure sensor body, and the pressure sensor body is in contact with the outer wall of the feeding chute.

[0008] Preferably, the feed pipe is located at the top of the V-type classifier body, and the rubber hose near the feed pipe is detachably connected to the feed pipe via a flange.

[0009] Preferably, the telescopic rods are arranged symmetrically, and the fourth connecting blocks are arranged evenly.

[0010] Preferably, one side of the first positioning block is arc-shaped, and one side of the first connecting block is arc-shaped.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, the structure consisting of a first positioning block, a first connecting block, a hydraulic cylinder, a second connecting block, a second positioning block, and a feeding chute is provided. The connection between the first positioning block and the first connecting block allows the hydraulic cylinder to rotate relative to the first connecting block and the first positioning block when the output shaft of the hydraulic cylinder retracts or extends. When the output shaft of the hydraulic cylinder retracts or extends, it acts on the second connecting block, causing the second connecting block and the second positioning block to rotate relative to each other. When the second positioning block rotates, it drives the feeding chute to rotate, thereby changing the feeding angle of the feeding chute. This can reduce the material flow rate entering the V-type classifier body, allowing the material to be fully dispersed and screened out in the classifier, reducing the circulating load, thereby solving the material segregation phenomenon and reducing the power consumption of the raw material process.

[0013] 2. In this utility model, the structure consisting of a feeding chute, mounting block, spring, pressure sensor body, and controller, etc., causes the feeding chute to rotate and act on the pressure sensor body, generating different pressures on the pressure sensor body. When it rotates to a certain angle, that is, when the pressure sensor body obtains certain information, the pressure sensor body transmits the obtained information to the controller. The controller then controls the hydraulic cylinder to stop running, thereby positioning the feeding chute at the required angle. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0020] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0021] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description.

[0024] Please see Figure 1-3 This utility model provides a technical solution:

[0025] An adjustable V-type air classifier includes a V-type air classifier body 1, a discharge chute 9, and a feed pipe 19. A mounting frame 2 is provided on one side of the V-type air classifier body 1. A mounting plate 3 is fixedly connected to the top of the mounting frame 2. A first positioning block 4 is fixedly connected to the top of the mounting plate 3. A first connecting block 5 is rotatably connected to the outer side of the first positioning block 4 via a rotating shaft. A hydraulic cylinder 6 is mounted on the outer side of the first connecting block 5. A second connecting block 7 is fixedly connected to the end of the output shaft of the hydraulic cylinder 6. A second positioning block 8 is rotatably connected to the outer side of the second connecting block 7 via a rotating shaft. The second positioning block 8 is fixedly connected to the discharge chute 9. A third positioning block 10 is fixedly connected to the upper surface of the mounting plate 3. The outer side of the third positioning block 10 is connected to... A third connecting block 11 is rotatably connected via a rotating shaft. A telescopic rod 12 is fixedly connected to the outside of the third connecting block 11. A fourth connecting block 13 is fixedly connected to the end of the telescopic rod 12 away from the third connecting block 11. A connecting shaft 14 is rotatably connected to the outside of the fourth connecting block 13 via a rotating shaft. A mounting block 15 is fixedly connected to the end of the connecting shaft 14 away from the fourth connecting block 13. A spring 16 is fixedly connected to one side of the mounting block 15 where the connecting shaft 14 is located. A pressure sensor body 17 is installed at the other end of the spring 16. A controller 18 that can control the hydraulic cylinder 6 is installed on the upper surface of the mounting plate 3. Rubber hoses 20 are detachably connected to both ends of the discharge chute 9 via flanges.

[0026] The controller 18 is electrically connected to the pressure sensor body 17, which is in contact with the outer wall of the feeding chute 9. This arrangement allows the rotation angle of the feeding chute 9 to be determined by the pressure borne by the pressure sensor body 17. The feed pipe 19 is located on the top of the V-type classifier body 1. The rubber hose 20 on the side near the feed pipe 19 is detachably connected to the feed pipe 19 via a flange. This arrangement allows the rubber hose 20 to rotate and deform relative to the feeding chute 9 when it rotates. The rubber hose 20 on one side is connected to the feed pipe 19, allowing the powder entering the feeding chute 9 to enter the feed pipe 19 through the rubber hose 20. The telescopic rods 12 are symmetrically arranged, and the fourth connecting blocks 13 are evenly arranged. This arrangement allows for the installation of the mounting block 15. One side of the first positioning block 4 is arc-shaped, and one side of the first connecting block 5 is arc-shaped. This arrangement facilitates the relative rotation of the first positioning block 4 and the first connecting block 5.

[0027] Workflow: All electrical appliances in this utility model are equipped with an external power supply or a built-in battery. When it is necessary to change the feeding angle of the feeding chute 9 to reduce the material flow rate entering the V-type classifier body 1 through the feed pipe 19, so that the material is fully dispersed and more finished products are screened out in the classifier, reducing the circulating load and thus solving the material segregation problem, the hydraulic cylinder 6 is activated. The hydraulic cylinder 6 can rotate relative to the first connecting block 5 and the first positioning block 4. When the output shaft of the hydraulic cylinder 6 extends, it will act on the second connecting block 7, causing the second connecting block 7 and the second positioning block 8 to rotate relative to each other. When the second positioning block 8 rotates, it will drive the feeding chute 9 to rotate, thereby changing the feeding angle of the feeding chute 9. When the feeding chute 9 rotates, it will act on the pressure sensor body 17, generating different pressures on the pressure sensor body 17. The pressure sensor body 17 acts on the spring 16, and the spring 16 acts on the mounting block 15, thereby compressing the spring 16. When it rotates to a certain angle, that is, when the pressure sensor body 17 obtains... When certain information is received, the pressure sensor body 17 transmits the received information to the controller 18, which is mounted via the mounting plate 3. The mounting plate 3 is mounted via the mounting bracket 2. The controller 18 controls the hydraulic cylinder 6 to stop running, thereby positioning the discharge chute 9 at the required angle. During this process, the mounting block 15 can drive the connecting shaft 14 to rotate relative to the fourth connecting block 13. The fourth connecting block 13 drives the telescopic rod 12 to rotate relative to each other while extending and retracting. The telescopic rod 12 drives the third connecting block 11 to rotate relative to the third positioning block 10, so that the pressure sensor body 17 can always be in contact with the discharge chute 9, thereby determining the rotation angle of the discharge chute 9. When the discharge chute 9 rotates, it will drive the rubber hose 20 to rotate and deform relative to each other. One side of the rubber hose 20 is connected to the feed pipe 19, so that the powder entering the discharge chute 9 can enter the feed pipe 19 through the rubber hose 20, and then enter the V-type classifier body 1 from the feed pipe 19 to perform a series of powder classification operations.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
