Description

Technical Field

[0001] This utility model relates to the field of dust filtration technology for shot blasting machines, specifically a dust purification device for shot blasting cleaning machines. Background Technology

[0002] Shot blasting machines use shot blasters to propel shot at high speed onto the surface of workpieces. The impact of the shot removes impurities from the workpiece surface and generates compressive stress, improving the fatigue strength and corrosion resistance of the workpiece. It has a good cleaning effect and is widely used in the field of workpiece surface treatment.

[0003] Existing dust collectors typically have a cyclone dust collector installed at the front end. This is primarily for pre-treatment and to reduce the load on subsequent dust collectors. The cyclone dust collector uses centrifugal force to separate dust from the airflow, effectively removing most large dust particles beforehand, thus reducing the load on subsequent dust collectors and extending their service life. However, the cyclone dust collector and the subsequent dust collector are two independent systems, requiring separate cleaning during dust removal, which is a cumbersome process. For example, the dust treatment system for shot blasting machines proposed in document number "CN215692853U" describes in paragraph

[0034] that the dust generated after the shot blasting machine operates is introduced into the dust treatment system, passing sequentially through a cyclone dust collector and a spray tower for filtration and purification to achieve better dust treatment. However, the cyclone dust collector and the spray tower are two independent systems, requiring separate cleaning of each, making the operation cumbersome. Therefore, we propose a dust purification device for shot blasting machines. Utility Model Content

[0004] This utility model provides a dust purification device for shot blasting machines, which has the advantage that the dust filtered by the dust collector and the cyclone dust collector will be collected and stored in the dust collection box, and can be centrally discharged, thus solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A dust purification device for a shot blasting machine includes a cyclone dust collector, a dust collector, and a horizontally arranged support frame. Multiple supports are provided at the bottom of the support frame. The outlet of the dust collector is connected to the inlet of the cyclone dust collector through a pipe. The cyclone dust collector is set inside the frame, while multiple support frames are provided at the bottom of the dust collector. Both the support frames and the frame are installed on the top of the support frame. A dust collection box is provided below the support frame. The discharge ports at the bottom of the dust collector and the cyclone dust collector are connected to the dust collection box. A discharge device is provided at the bottom of the dust collection box.

[0006] Optionally, an impeller feeder is provided at the bottom of the cyclone dust collector.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Reference Figures 1 to 4 This utility model provides a technical solution: a dust purification device for a shot blasting machine, including a horizontally arranged support frame 1, with multiple supports 14 at the bottom of the support frame 1, the supports 14 being supported on the ground, a cyclone dust collector 4 and a dust collector 5 both located above the support frame 1, and the outlet of the dust collector 5 being connected to the inlet of the cyclone dust collector 4 via a pipe, such as... Figure 1 and Figure 2 As shown, the cyclone dust collector 4 is installed inside the frame 3. The bottom of the frame 3 is connected to the support frame 1, while the bottom of the dust collector 5 is provided with multiple support frames 6, which are installed on the top of the support frame 1. When using, such as Figure 2 and Figure 3 As shown, the inlet of the cyclone dust collector 4 is connected to the outlet of the induced draft fan 15 through a pipe. The inlet of the induced draft fan 15 is connected to the dust collection hood 20 through a pipe. There is at least one dust collection hood 20. The dust collection hood 20 is installed on the body of the shot blasting machine. When the induced draft fan 15 is turned on, it quickly draws the dust out of the shot blasting machine body and enters from the top inlet of the cyclone dust collector 4 under the guidance of the induced draft fan 15. Then, the fine dust after being removed by the cyclone dust collector 4 enters the dust collector 5 from the top outlet of the cyclone dust collector 4 for further screening. The dust collector 5 is a bag dust collector.

[0020] like Figure 1 and Figure 2As shown, a dust collection box 7 is provided below the support frame 1. The discharge ports at the bottom of the dust collector 5 and the cyclone dust collector 4 are connected to the dust collection box 7. Specifically, an impeller feeder 2 is provided at the bottom of the cyclone dust collector 4. Elastic expansion joints 9 are installed at the bottom of the impeller feeder 2 and the bottom of the dust collector 5, respectively. The bottom of the elastic expansion joint 9 is connected to the top of the dust collection box 7. The elastic expansion joint 9 is an elastic corrugated pipe joint or an elastic flexible shock-absorbing pipe. The elastic expansion joint 9 can not only be connected to the outlet at the bottom of the dust collector 5 and the cyclone dust collector 4, but also correct the height difference between the top of the dust collection box 7 and the bottom of the dust collector 5 and the impeller feeder 2. Next, this application further improves the dust collection box 7. At least two mounting seats 10 are symmetrically provided on both sides of the dust collection box 7. The mounting seats 10 are specifically distributed at the ends near both sides of the dust collection box 7. Guide posts 12 are vertically provided at the bottom of the mounting seats 10. Each guide post 12 is movably placed within a guide seat 11, and each guide seat 11 is mounted on a fixed frame 13. The top of the fixed frame 13 is connected to the support frame 1, such as... Figure 2 As shown, the fixed frame 13 can not only support the dust collection box 7, but also support the support frame 1 together with the bracket 14, making the support frame 1 more stable; Next, a pressure sensor 18 is installed on the top of at least one guide seat 11. Since the guide column 12 is movably positioned within the guide seat 11, when there is a heavy object inside the dust collection box 7, the dust collection box 7 moves horizontally downwards along the guide seat 11 under the guiding action of the guide column 12. Therefore, installing one pressure sensor 18 is sufficient. However, it is also possible to install pressure sensors 18 on the top of each guide seat 11. The pressure sensor 18 is connected to a controller, which is located inside the control cabinet 21. Figure 1 As shown, the control cabinet 21 is mounted on the bracket 14, and the cabinet door of the control cabinet 21 is also equipped with buttons and an operation panel connected to the controller. Specifically, the dust passing through the cyclone dust collector 4 will gradually enter the dust collection box 7 from the impeller feeder 2. When the dust collector 5 discharges ash, it will also discharge the dust into the dust collection box 7. The weight of the dust in the dust collection box 7 is monitored in real time by the pressure sensor 18.

[0021] Furthermore, a discharge device is provided at the bottom of the dust collection box 7. The discharge device includes a spiral shaft 22 located inside the bottom of the dust collection box 7. The bottom cross section of the dust collection box 7 is a conical structure, and the spiral shaft 22 is located inside the bottom of the conical structure, so that the dust can automatically accumulate in the direction of the spiral shaft 22. The bottom of one end of the dust collection box 7 is provided with a discharge pipe 16 coaxially arranged with the screw shaft 22. The end of the discharge pipe 16 is provided with an end cap (not labeled in the figure). A discharge valve 17 is provided on the side of the discharge pipe 16. One end of the screw shaft 22 extends into the discharge pipe 16, and one end of the screw shaft 22 is rotatably connected to the end cap. The other end is rotatably connected to the end of the dust collection box 7. The end of the screw shaft 22 away from the discharge pipe 16 is connected to the drive motor 8. The drive motor 8 is set on the dust collection box 7 and is connected to the controller. Specifically, when the weight of dust in the dust collection box 7 reaches the set value, the controller controls the drive motor 8 to rotate, thereby driving the spiral shaft 22 to rotate for automatic dust removal, or the controller controls the alarm to sound an alarm. The alarm is set on the control cabinet 21 to remind the staff to clean it as soon as possible.

[0022] Based on the above embodiments, further optimization can be achieved by providing multiple ultrasonic level gauges 23 on the top side of the dust collection box 7. The ultrasonic level gauges 23 are located below each elastic expansion joint 9. The ultrasonic level gauges 23 can monitor the height of dust accumulation below each elastic expansion joint 9. When the dust accumulates to a preset height, the automatic control of the spiral shaft 22 is activated to reciprocate, thereby leveling the accumulated dust.

[0023] Based on the above embodiments, further optimization is possible. The top of the guide seat 11 is provided with a support pad 19, and the pressure sensor 18 can be placed on the top of the support pad 19. This can avoid direct impact between the mounting seat 10 and the guide seat 11, and also protect the pressure sensor 18.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
