Description

Technical Field

[0001] This utility model relates to the field of automotive exhaust gas treatment technology, and in particular to a corrosion-resistant electric rotary drum. Background Technology

[0002] An electric rotary drum is a device used to extract exhaust gas from a car engine. It usually uses a fan connected to an extraction pipe, which is then connected to the car's exhaust pipe. The fan then draws the exhaust gas into the purifier for purification before it is discharged. It is a common car maintenance tool.

[0003] After normal use, the existing electric rotary drum extracts the exhaust gas through the extraction pipe and then uses a motor to drive a winding device to return the extraction pipe to its original position for the next use. However, after the exhaust gas is extracted, a large number of particles contained in the exhaust gas remain on the inner wall of the extraction pipe. If these residual exhaust gas particles are not cleaned in time, they will cause corrosion to the inner wall of the pipe, thereby reducing the durability of the extraction pipe and shortening its service life. There is room for improvement. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a corrosion-resistant electric rotary drum.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A corrosion-resistant electric drum includes a support frame, an installation assembly fixedly connected to the back of the support frame, a servo motor fixedly connected to the right side of the support frame, a winding roller fixedly connected to the output end of the servo motor, a suction pipe wound around the surface of the winding roller, an exhaust port connected to one end of the suction pipe and a connecting pipe connected to the other end, an anti-corrosion assembly fixedly connected to the lower surface of the support frame, and a collection assembly fixedly connected to the lower surface of the support frame.

[0007] The corrosion protection component is used to quickly flush the inside of the extraction pipe to reduce the corrosive effect of exhaust gas on the inner wall of the pipe.

[0008] Preferably, the anti-corrosion component includes a cleaning tank, with an inlet pipe connected to the left side of the cleaning tank, a strip frame fixedly connected to the front of the cleaning tank, a cover plate fixedly connected to the upper surface of the strip frame by four locking bolts, and a delivery pump installed on the inner bottom wall of the strip frame.

[0009] Preferably, the input end of the delivery pump is connected to an inlet pipe, and the output end is connected to a discharge pipe. The end of the discharge pipe away from the delivery pump is connected to a first corrugated pipe, and the upper surface of the cover plate is provided with a through hole that matches the first corrugated pipe.

[0010] Preferably, the collection assembly includes a collection box, the lower surface of which is connected to a drain pipe, a control valve is installed on the surface of the drain pipe, and the upper surface of the collection box is connected to a second corrugated pipe.

[0011] Preferably, the mounting assembly includes a positioning frame, the inner wall of which has a sliding groove, a positive and negative threaded rod rotatably connected to the inner wall of the sliding groove, a handwheel fixedly connected to the left end of the positive and negative threaded rod, two sliders slidably connected to the inner wall of the sliding groove, and mounting brackets fixedly connected to the back of the two sliders, and two mounting bolts threadedly connected to the inner wall of the mounting bracket.

[0012] Preferably, the two sliders are threadedly connected to the positive and negative threads on the surface of the positive and negative threaded rod, respectively.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. With the inclusion of anti-corrosion and collection components, during use, the first and second corrugated pipes can be connected to the connecting pipes and exhaust ports at both ends of the extraction pipe. The cleaning liquid in the cleaning tank is then pumped into the extraction pipe by a delivery pump, thereby flushing away any residual exhaust gas particles in the extraction pipe. This ensures that no exhaust gas particles remain in the extraction pipe, preventing corrosion of the inner wall of the extraction pipe by the exhaust gas particles and extending the service life of the extraction pipe.

[0015] 2. Through the installation component settings, during use, the handwheel can be used to drive the forward and reverse threaded rods to rotate, thereby changing the distance between the two mounting brackets through the two sliders. This allows the support bracket to be adjusted to the installation position at will according to the actual situation, providing high flexibility. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1, referring to Figure 1 and Figure 2 A corrosion-resistant electric drum includes a support frame 1, an installation assembly fixedly connected to the back of the support frame 1, a servo motor 2 fixedly connected to the right side of the support frame 1, a winding roller 3 fixedly connected to the output end of the servo motor 2, a suction pipe 4 wound around the surface of the winding roller 3, an exhaust port 5 connected to one end of the suction pipe 4 and a connecting pipe 6 connected to the other end, an anti-corrosion assembly fixedly connected to the lower surface of the support frame 1, and a collection assembly fixedly connected to the lower surface of the support frame 1.

[0022] The anti-corrosion component is used to quickly flush the inside of the exhaust pipe 4 to reduce the corrosive effect of exhaust gas on the inner wall of the pipe.

[0023] The anti-corrosion component includes a cleaning tank 7, an inlet pipe 8 connected to the left side of the cleaning tank 7, a strip frame 9 fixedly connected to the front of the cleaning tank 7, a cover plate 11 fixedly connected to the upper surface of the strip frame 9 by four locking bolts 10, and a delivery pump 12 installed on the inner bottom wall of the strip frame 9.

[0024] The input end of the delivery pump 12 is connected to the water inlet pipe 13, and the output end is connected to the discharge pipe 14. The end of the discharge pipe 14 away from the delivery pump 12 is connected to the first corrugated pipe 15, and the upper surface of the cover plate 11 is provided with a through hole that is compatible with the first corrugated pipe 15.

[0025] The collection assembly includes a collection box 16, a drain pipe 17 connected to the lower surface of the collection box 16, a control valve 18 installed on the surface of the drain pipe 17, and a second corrugated pipe 19 connected to the upper surface of the collection box 16.

[0026] After the extraction is completed, the first corrugated pipe 15 is connected to the connecting pipe 6, and the second corrugated pipe 19 is connected to the exhaust port 5. After the delivery pump 12 is turned on, the delivery pump 12 can pump the cleaning liquid in the cleaning tank 7 into the extraction pipe 4 through the water inlet pipe 13 and the discharge pipe 14, thereby cleaning the exhaust gas particles attached to the extraction pipe 4, ensuring that the exhaust gas particles will not remain in the extraction pipe 4 and cause corrosion to the inner wall of the pipe, improving the protection of the extraction pipe 4 and extending the service life of the extraction pipe 4.

[0027] Example 2: Refer to Figure 1 and Figure 3The mounting assembly includes a positioning frame 20, the inner wall of which is provided with a sliding groove. A positive and negative threaded rod 21 is rotatably connected to the inner wall of the sliding groove. A handwheel 22 is fixedly connected to the left end of the positive and negative threaded rod 21. Two sliders 23 are slidably connected to the inner wall of the sliding groove, and a mounting frame 24 is fixedly connected to the back of each slider 23. Two mounting bolts 25 are threadedly connected to the inner wall of the mounting frame 24. The two sliders 23 are threadedly connected to the positive and negative threads on the surface of the positive and negative threaded rod 21, respectively.

[0028] Rotating the handwheel 22 can drive the forward and reverse threaded rods 21 to rotate, thereby changing the distance between the two mounting brackets 24 through the two sliders 23, so that the two mounting brackets 24 can be installed in positions of different sizes, which is highly flexible.

[0029] Working principle: First, according to the size and width of the installation location, turn the handwheel 22 to rotate the forward and reverse threaded rod 21. This rotation drives the two mounting brackets 24 to move towards their opposite faces via the two sliders 23, thereby changing the distance between the two mounting brackets 24. This allows the two mounting brackets 24 to be installed in any position, providing high flexibility. After installation, use the remote control to turn on the servo motor 2. The servo motor 2 drives the winding roller 3 to rotate, which in turn causes the exhaust pipe 4 to extend. This connects the connecting pipe 6 to the vehicle's exhaust pipe, while the exhaust port 5 connects to the fan and purifier. The fan then extracts the exhaust gas from the exhaust pipe. After extraction, the servo motor 2 automatically drives the exhaust pipe 4 back to its original position. At this point, the first corrugated pipe 15 is moved to connect with the connecting pipe 6, and the second corrugated pipe 19 is moved to connect with the exhaust port 5. The delivery pump 12 is turned on, and the delivery pump 12 pumps the cleaning liquid in the cleaning tank 7 into the exhaust pipe 4 through the water inlet pipe 13 to quickly flush the inner wall of the exhaust pipe 4, thereby cleaning the residual exhaust gas particles attached to the inner wall of the exhaust pipe 4 and ensuring that they will not adhere to the inner wall of the exhaust pipe 4 for a long time and cause corrosion to the exhaust pipe 4. This improves the corrosion resistance of the exhaust pipe 4 and extends its service life. In addition, the wastewater containing exhaust gas particles enters the collection tank 16 for centralized collection and treatment, which will not cause pollution and has a better environmental protection effect.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
