Description

Technical Field

[0001] This utility model relates to the technical field of powder coating booths, specifically to a cyclone separator. Background Technology

[0002] During powder coating in a powder booth, the process is carried out using a spray gun. Once sufficient powder is applied to the workpiece, excess powder falls into the booth and is sucked away through pipes. To separate the excess powder from the gas, a cyclone separator is used. The cyclone separator separates the gas and powder using centrifugal force. After the gas enters the separator, larger dust particles are separated and discharged through the bottom, while the ultrafine powder flows with the gas to subsequent filtration units for further filtration. However, the airflow inside the cyclone separator is complex, exhibiting eddies and turbulence. These complex airflow movements can cause larger particles that have settled on the separator walls to be re-entrained and re-enter the airflow, eventually being discharged with the gas. These larger particles increase the filtration pressure of subsequent filtration units, thus reducing their filtration efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a cyclone separator to solve the problem mentioned in the background art that current cyclone separators on the market cannot completely remove large particles during separation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cyclone separator, comprising a separation body supported at its bottom by a support frame, a dust discharge pipe at the bottom of the separation body for discharging dust particles, an exhaust port and an inlet on both sides of the top of the separation body for intake of dust-laden gas and discharge of purified gas, respectively, a connecting pipe detachably installed at the top of the exhaust port, an installation assembly on the outside of the connecting pipe, two sets of dust collection hoppers symmetrically arranged at the bottom of the installation assembly, and a cleaning and unblocking assembly inside the dust collection hopper for cleaning and unblocking the filter assembly installed inside the connecting pipe, the filter assembly being arranged at right angles and rotating alternately for filtration.

[0005] Preferably, mounting plates are integrally installed on both sides of the connecting pipe, and the outer side of the mounting plates is evenly distributed with perforations for the disassembly and installation of bolts or screws. Two sets of reserved openings are also symmetrically arranged at the bottom of the connecting pipe, and the filter assembly inside the connecting pipe is located in the middle position.

[0006] Preferably, the filter assembly includes a first filter plate, a second filter plate, a rotating shaft, and a control motor. The first filter plate and the second filter plate are connected by the rotating shaft and are arranged vertically. The control motor is coaxially connected to one side of the rotating shaft. After the first filter plate or the second filter plate is rotated to a horizontal state by the rotating shaft, it completely covers the reserved opening.

[0007] Preferably, one side of the mounting assembly is pushed and moved by an electric push rod, and the mounting assembly includes a mounting cover, a mounting base plate and a slider. The bottom of the mounting cover is detachably installed from the mounting base plate, and the bottom of the mounting cover is provided with a slider that slides in a groove at the top of the connecting pipe.

[0008] Preferably, the mounting base plate includes a middle plate and side plates, wherein the side plates are symmetrically arranged on both sides of the middle plate, and the middle plate and the side plates are the same size.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0015] Please see Figure 1-5 This utility model provides a technical solution: a cyclone separator, comprising a separation body 1, the bottom of which is supported by a support frame 2. The bottom of the separation body 1 is provided with a dust discharge pipe 3 for discharging dust particles. The top two sides of the separation body 1 are respectively provided with an exhaust port 4 and an air inlet 5 for the intake of dust-laden gas and the discharge of purified gas. A connecting pipe 6 is detachably installed at the top of the exhaust port 4. An installation assembly 9 is provided outside the connecting pipe 6. Two sets of dust collection hoppers 10 are symmetrically arranged at the bottom of the installation assembly 9. A cleaning and unblocking assembly 11 is provided inside the dust collection hopper 10 for cleaning and unblocking the filter assembly 8 installed inside the connecting pipe 6. The filter assembly 8 is arranged at right angles and performs rotating and alternating filtering.

[0016] This application provides a cyclone separator. Specifically, during use, the entire separator body 1 is supported by the support frame 2. After the power is turned on, dust-laden gas from the outside enters the interior of the separator body 1 through the air inlet 5. Since the separator body 1 is designed with a cylindrical upper part and a conical lower part, the gas rotates inside the cylindrical structure. Then, upon reaching the interior of the conical structure, the radius of rotation gradually decreases, and the tangential velocity increases. During rotation, the particles are subjected to a large centrifugal force and are thrown against the wall of the separator, losing their inertial force and adhering to the wall. The momentum of the downward axial velocity falls along the wall and enters the ash discharge pipe 3, and is discharged from the ash discharge pipe 3. Meanwhile, the rotating downward external swirling airflow continuously flows into the center of the separation body 1 during the descent, forming a centripetal radial airflow, which constitutes a rotating upward internal swirling flow, and is then discharged through the exhaust port 4. Due to the complex movement of the internal airflow of the entire separation body 1, a small number of large particles will enter the position of the exhaust port 4, and then reach the connecting pipe 6 through the exhaust port 4. Since the connecting pipe 6 is equipped with a filter assembly 8, the large particles can be filtered through the filter assembly 8. Since the filter assembly 8 can rotate alternately, a timer can also be set in this application to control the filter assembly 8 to rotate alternately intermittently, thereby ensuring that the filter assembly 8 can perform continuous and efficient filtration. At the same time, when the filter assembly 8 rotates alternately, the filter assembly 8 can also be cleaned by the cleaning and unblocking component 11 inside the ash collection hopper 10.

[0017] Among them, according to Figure 2 and Figure 5 As shown, mounting plates 61 are integrally installed on both sides of the connecting pipe 6, and the outer side of the mounting plates 61 is evenly distributed with perforations for the disassembly and installation of bolts or screws. Two sets of reserved openings 62 are also symmetrically arranged at the bottom of the connecting pipe 6, and the filter assembly 8 inside the connecting pipe 6 is located in the middle position.

[0018] The filter assembly 8 includes a first filter plate 81, a second filter plate 82, a rotating shaft 83, and a control motor 84. The first filter plate 81 and the second filter plate 82 are connected by the rotating shaft 83 and are arranged vertically. The control motor 84 is coaxially connected to one side of the rotating shaft 83. After the first filter plate 81 or the second filter plate 82 is rotated to a horizontal state by the rotating shaft 83, it completely covers the reserved opening 62. Specifically, when the filter assembly 8 rotates alternately, the control motor 84 needs to be started, causing it to drive the rotating shaft 83 at its top to rotate. When the rotating shaft 83 rotates, the first filter plate 81 and the second filter plate 82 will rotate. Thus, when the first filter plate 81 is in a vertical state, it is the first filter plate 81 that is filtering. If the second filter plate 82 is in a vertical state, it is the first filter plate 81 that is filtering. Similarly, if the first filter plate 81 is in a horizontal state, it will be cleaned by the cleaning and unblocking assembly 11 at its bottom. If the second filter plate 82 is in a horizontal state, it will be cleaned by the cleaning and unblocking assembly 11 at its bottom.

[0019] Furthermore, during cleaning and unblocking, according to Figure 2 , Figure 3 and Figure 4 As shown, one side of the mounting assembly 9 is pushed and moved by the electric push rod 7, and the mounting assembly 9 includes a mounting cover 91, a mounting base plate 92 and a slider 93. The bottom of the mounting cover 91 is detached from the mounting base plate 92, and the bottom of the mounting cover 91 is provided with a slider 93 that slides in the groove at the top of the connecting pipe 6.

[0020] The mounting base plate 92 includes a middle plate 921 and a side plate 922, wherein the side plate 922 is symmetrically arranged on both sides of the middle plate 921, and the middle plate 921 and the side plate 922 have the same size. A through opening 923 is provided in the middle of the side plate 922, and a dust collection hopper 10 is integrally installed on the bottom outer side of the through opening 923. Based on the rotational alternation time of the filter assembly 8, the electric push rod 7 is controlled to extend and retract. When it extends and retracts, it drives the mounting base plate 92 on the mounting assembly 9 to move. When the first filter plate 81 is in a horizontal state, the reserved opening 62 at the bottom of the first filter plate 81 corresponds to the ash collection hopper 10 on one side, and the other reserved opening 62 is sealed by the middle plate 921. Thus, the cleaning and unblocking assembly 11 inside the ash collection hopper 10 at the bottom of the first filter plate 81 is activated, and the first filter plate 81 can be cleaned. Similarly, when the second filter plate 82 is in a horizontal state, the cleaning and unblocking assembly 11 can also be used to clean and unblock it.

[0021] Furthermore, according to Figure 5As shown, the cleaning and unblocking assembly 11 includes a fixed cover 111, a telescopic cylinder 112, a drive motor 113, a connecting shaft 114, a cleaning brush 115, and a mounting bracket 116. The top of the fixed cover 111 is connected to the mounting bracket 116, and the outer side of the mounting bracket 116 is connected to the inner wall of the dust collection hopper 10. The telescopic cylinder 112 is provided inside the lower part of the fixed cover 111, and the top of the telescopic cylinder 112 is provided with a drive motor 113. The top of the drive motor 113 is connected to the cleaning brush 115 through the connecting shaft 114. The cleaning brush 115 moves up and down through the through-hole 923 and the reserved opening 62 to clean the first filter plate 81 or the second filter plate 82 covering the top of the reserved opening 62. When cleaning, the telescopic cylinder 112 needs to be activated, which drives the top drive motor 113 and the connecting shaft 114 to rise. When the cleaning brush 115 at the top of the connecting shaft 114 contacts or engages with the first filter plate 81 or the second filter plate 82, the drive motor 113 is controlled to work, so that it drives the cleaning brush 115 to rotate through the connecting shaft 114, thus completing the purpose of cleaning the first filter plate 81 or the second filter plate 82. In this application, the connecting pipe 6 is configured in at least two sets, and the first filter plate 81 and the second filter plate 82 in the two sets of connecting pipe 6 are arranged in opposite directions. That is, if the first filter plate 81 inside one connecting pipe 6 is in a vertical state, then the second filter plate 82 inside the other connecting pipe 6 is in a vertical state.
