Description

Technical Field

[0001] The utility model relates to the technical field of powder recovery systems for electrostatic powder spraying, and specifically relates to an ultrasonic vibrating screen for a powder spraying booth. Background Art

[0002] During the electrostatic powder spraying process, the overspray powder that has not been adsorbed onto the workpiece surface will be recovered and reused through the powder recovery system. Before reuse, the recovered powder will be sieved to prevent impurities from being mixed in the recovered powder.

[0003] Currently, the powder screening process is generally completed by a vibrating screen. The traditional vibrating screen uses a vibrating motor as the vibration source, and its screening capacity and efficiency are limited. Especially in the working conditions with relatively high screening accuracy, the screening efficiency drops significantly, and it is difficult to undertake the work of large powder volume spraying or high-precision powder screening. Especially for high-precision screening, it is very difficult to screen with the current vibrating screen using a vibrating motor as the vibration source.

[0004] Therefore, we urgently need to provide an ultrasonic vibrating screen for a powder spraying booth. Content of the Utility Model

[0005] The purpose of the utility model is to provide an ultrasonic vibrating screen for a powder spraying booth to solve the problem that the traditional vibrating screen uses a vibrating motor as the vibration source, and its screening capacity and efficiency are limited as mentioned in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An ultrasonic vibrating screen for a powder spraying booth, including a powder inlet and a vibrating screen housing. The powder inlet is fixedly connected to the upper left of the vibrating screen housing. A pressing device is arranged at the left end of the vibrating screen housing, and a screening mechanism is arranged inside the vibrating screen housing.

[0007] The screening mechanism includes a powder outlet, a screen mesh, an ultrasonic vibrator, and a gasket. The powder outlet is fixedly connected to the lower end of the vibrating screen housing. The screen mesh is fixedly connected to the middle position inside the vibrating screen housing. The ultrasonic vibrator is fixedly connected to the right end of the screen mesh. The gasket is fixedly connected to the outer edge of the vibrating screen housing.

[0008] Further improvement lies in that the vibrating screen housing is divided into upper and lower parts, and the right end connection of the two parts is hinged through a hinge. The left ends of the two parts are relatively fixed through the pressing device. Thus, after opening the pressing device, the upper half of the vibrating screen housing can be pulled open, and then the upper end of the screen mesh can be cleaned.

[0009] A further improvement lies in that a material receiving mechanism is connected to the lower end of the powder outlet. The material receiving mechanism includes a material receiving tank, a fixed frame, a spring, a baffle, and a plug rod. The material receiving tank is fixedly connected to the lower end of the powder outlet. The fixed frame is fixedly connected to the outer sides of the left and right ends at the pipe orifice of the material receiving tank. The spring is fixedly connected to the end of the fixed frame away from the material receiving tank. The baffle is fixedly connected to the other end of the spring. The plug rod is fixedly connected to the middle position inside the baffle.

[0010] A further improvement lies in that limit holes are provided at the middle positions of the left and right ends at the tank orifice of the material receiving tank and at the middle position of the inner side of the fixed frame away from the material receiving tank. The outer side of the plug rod is slidably connected to the inner side of the sliding hole. Thus, when the spring bounces to drive one end of the baffle, the plug rod can be driven to slide along the inner side of the sliding hole.

[0011] A further improvement lies in that insertion holes are provided at the middle positions of the left and right ends at the lower part inside the powder outlet. One end of the outer side of the plug rod close to the powder outlet is inserted into the inner side of the insertion hole. The outer side of the powder outlet is slidably connected to the inner side of the tank orifice of the material receiving tank. Thus, the tank orifice of the material receiving tank is slid to the outside of the powder outlet. Then the plug rod is released. The spring rebounds and pushes the baffle towards the powder outlet, driving the plug rod to insert into the insertion hole inside the powder outlet. Thus, the material receiving tank can be fixed to the lower end of the powder outlet.

[0012] A further improvement lies in that a rubber pad is fixedly connected to the inner side of the tank orifice of the material receiving tank. Thus, when the material receiving tank is fixed to the outside of the powder outlet, the rubber pad at the inner side of the tank orifice of the material receiving tank contacts the outer side of the powder outlet, enabling the contact part between the material receiving tank and the powder outlet to be sealed.

[0013] In summary, the present application discloses an ultrasonic vibrating screen for a powder spraying booth.

[0014] In this technical solution, the ultrasonic vibrator needs to be used in combination with an ultrasonic generator, making the vibration effect more direct, further increasing the sieving capacity, and ensuring that the dust is completely sieved.

[0015] Furthermore, after first pulling the plug rod to the left and right ends so that the plug rod is no longer inside the tank orifice of the material receiving tank, then sliding the tank orifice of the material receiving tank to the outside of the powder outlet, and then releasing the plug rod, the spring rebounds and pushes the baffle towards the powder outlet, driving the plug rod to insert into the insertion hole inside the powder outlet. Thus, the material receiving tank can be fixed to the lower end of the powder outlet. After the powder filtered from the vibrating screen housing falls from the lower powder outlet, it will directly fall into the material receiving tank for collection, preventing the powder from being scattered by the airflow after falling.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 - 4 , the present utility model provides a technical solution: Embodiment 1:

[0023] An ultrasonic vibrating screen for a powder spraying booth includes a powder inlet 1 and a vibrating screen housing 2. The powder inlet 1 is fixedly connected to the upper left of the vibrating screen housing 2. A pressing device 3 is provided at the left end of the vibrating screen housing 2, and a screening mechanism is provided inside the vibrating screen housing 2.

[0024] The screening mechanism includes a powder outlet 4, a screen mesh 5, an ultrasonic vibrator 6, and a gasket 7. The powder outlet 4 is fixedly connected to the lower end of the vibrating screen housing 2. The screen mesh 5 is fixedly connected to the middle position inside the vibrating screen housing 2. The ultrasonic vibrator 6 is fixedly connected to the right end of the screen mesh 5. The gasket 7 is fixedly connected to the outer edge of the vibrating screen housing 2. The vibrating screen housing 2 is divided into upper and lower parts, and the right end connection of the two parts is hinged by a hinge, and the left ends of the two parts are relatively fixed by the pressing device 3. Thus, after opening the pressing device 3, the upper half of the vibrating screen housing 2 can be pulled open, and then the upper end of the screen mesh 5 can be cleaned.

[0025] The pressing device 3 includes a screw, a nut, two hinged fixing plates and a handle. The screw is fixedly connected to the upper left side of the vibrating screen housing 2. The nut is threadedly connected to the outer end of the screw. One of the two hinged fixing plates is fixedly connected to the lower left end of the vibrating screen housing 2, and the other plate is fixed to the outer end of the screw through the nut. The handle is rotatably connected to the outer end of the fixing plate. Thus, after removing the nut from the outer end of the screw and then pulling the handle to pull the fixing plate down from the outside of the screw, the pressing device 3 can be opened, and the upper and lower parts of the vibrating screen housing 2 are no longer relatively fixed, and the vibrating screen housing 2 can be opened to clean the screen mesh 5 therein. Embodiment 2:

[0026] Based on Embodiment 1: A material receiving mechanism is connected to the lower end of the powder outlet 4. The material receiving mechanism includes a material receiving tank 801, a fixing frame 802, a spring 803, a baffle 804 and a plug rod 805. The material receiving tank 801 is fixedly connected to the lower end of the powder outlet 4. The fixing frame 802 is fixedly connected to the outer sides of the left and right ends at the pipe orifice of the material receiving tank 801. The spring 803 is fixedly connected to the end of the inner side of the fixing frame 802 away from the material receiving tank 801. The baffle 804 is fixedly connected to the other end of the spring 803. The plug rod 805 is fixedly connected to the middle position inside the baffle 804. Limiting holes are provided at the middle positions of the left and right ends at the tank orifice of the material receiving tank 801 and at the middle position of the inner side of the fixing frame 802 away from the material receiving tank 801. The outer side of the plug rod 805 is slidably connected to the inner side of the sliding hole. Thus, when one end of the baffle 804 is driven by the spring 803 to bounce, the plug rod 805 can be driven to slide along the inner side of the sliding hole, thereby playing a role in limiting the movement of the plug rod 805.

[0027] Insertion holes are provided at the middle positions of the left and right ends below the inner part of the powder outlet 4. The outer side of the plug rod 805 near the powder outlet 4 is inserted into the inner side of the insertion hole. The outer side of the powder outlet 4 is slidably connected to the inner side of the tank orifice of the material receiving tank 801. Thus, by first pulling the plug rod 805 to the left and right ends so that the plug rod 805 is no longer located inside the tank orifice of the material receiving tank 801, then sliding the tank orifice of the material receiving tank 801 to the outside of the powder outlet 4, and then releasing the plug rod 805, the spring 803 rebounds to push the baffle 804 towards the powder outlet 4, driving the plug rod 805 to insert into the insertion hole inside the powder outlet 4, so that the material receiving tank 801 can be fixed to the lower end of the powder outlet 4, and the powder filtered from the vibrating screen housing 2 will directly fall into the material receiving tank 801 to be collected after falling from the lower powder outlet 4, preventing the powder from being blown away by the air flow after falling. Embodiment 3:

[0028] Based on Embodiment 2: A rubber pad is fixedly connected to the inner side of the mouth of the receiving tank 801. Thus, when the receiving tank 801 is fixed to the outside of the powder outlet 4, the rubber pad on the inner side of the mouth of the receiving tank 801 contacts the outside of the powder outlet 4, so that the contact between the receiving tank 801 and the powder outlet 4 can be kept sealed, thereby preventing the powder in the receiving tank 801 from floating out from the contact between the receiving tank 801 and the powder outlet 4.

[0029] Working principle: During use, first pull the insertion rod 805 to the left and right ends so that the insertion rod 805 is no longer inside the mouth of the receiving tank 801, then slide the mouth of the receiving tank 801 to the outside of the powder outlet 4, and then release the insertion rod 805. The spring 803 rebounds and pushes the baffle 804 towards the powder outlet 4, driving the insertion rod 805 to insert into the insertion hole inside the powder outlet 4, fixing the receiving tank 801 to the lower end of the powder outlet 4. Then start the ultrasonic oscillator 6 and put the powder to be filtered into the vibrating screen housing 2 from the powder inlet 1. After being filtered by the vibrating screen 5, it falls into the receiving tank 801 from the lower powder outlet 4, completing the filtration and collection of the powder.
