[0022] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings, but this does not limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0023] Example 1

[0024] The degreasing device for stainless steel pipe production described in this embodiment is as follows: Figure 1 、 Figure 2 and Figure 4 As shown in , it includes a cleaning tank 1, a sedimentation box 3 is provided on one side of the cleaning tank 1, and a cover plate for sealing the top of the sedimentation box 3 is hingedly connected to the side wall of the sedimentation box 3 by a hinge, one end of the hinge is fixed to the side wall of the sedimentation box 3 by a screw, and the other end of the hinge is fixed to the cover plate by a screw, so that the cover plate can be swung open and closed;

[0025] A first water pipe 2 is connected between the cleaning tank 1 and the sedimentation tank 3, and a first water pump 22 for pressurized delivery of the degreasing agent is installed on the first water pipe 2. The first water pipe 2 is divided into two sections. The water inlet and the water outlet of the first water pump 22 are respectively connected to the two sections of the first water pipe 2, and the other ends of the two sections of the first water pipe 2 are respectively connected to the cleaning tank 1 and the sedimentation tank 3. When the first water pump 22 is started, the degreasing agent in the cleaning tank 1 is pumped out through the first water pipe 2 and delivered to the sedimentation tank 3.

[0026] Several filter plates 13 with different apertures are horizontally installed in the sedimentation box 3. All filter plates 13 are arranged from bottom to top according to the aperture from large to small. In this embodiment, there are three filter plates 13 with three apertures of large, medium and small. The three filter plates 13 are located above the interface of the first water pipe 2. When the degreaser flows out from the interface of the first water pipe 2, the degreaser will first flow through the filter plate 13 with the largest aperture at the bottom, and filter the large volume of oil impurities in the degreaser through the filter plate 13. Then the degreaser will flow through the remaining filter plates 1 in sequence. 3. Filtering oily impurities of different volumes and filtering them by category can prevent small filter holes from being blocked by large impurities. The filter plates 13 are arranged from bottom to top according to their pore sizes, so that when the oily impurities on the upper filter plate 13 fall, they can pass through the filter holes of the lower filter plate 13 to avoid blockage. By setting the filter plates 13, larger impurities in the degreasing agent can be quickly precipitated at the inner bottom of the sedimentation box 3, thereby accelerating the precipitation time and effect of the degreasing agent.

[0027] The inner bottom of the sedimentation box 3 is inclined, and a drain port 12 for discharging impurities precipitated in the sedimentation box 3 is provided on the side wall of the sedimentation box 3. A valve is installed on the drain port 12. When the oil and impurities in the degreasing agent are deposited on the inner bottom of the sedimentation box 3, these oil and impurities will slide along the inclined inner bottom of the sedimentation box 3, so that these oil and impurities are accumulated on the side with lower terrain. When the drain port 12 is opened by the valve, these oil and impurities can be discharged, thereby preventing excessive accumulation of oil and impurities from clogging the filter plate 13.

[0028] A movable plate 16 that can move left and right is horizontally arranged in the sedimentation box 3, and the movable plate 16 is located in the upper half of the sedimentation box 3;

[0029] To further explain, Figure 1 、 Figure 2 and Figure 5As shown, in this embodiment, it is preferred to include two guide rods 15 that are aligned in parallel front and back. The two ends of all guide rods 15 are respectively fixed on the left and right inner side walls of the sedimentation box 3. The two guide rods 15 are independently covered with sliding sleeves 14, and the two sliding sleeves 14 are fixed to the movable plate 16; each sliding sleeve 14 can move along the rod body of the corresponding guide rod 15, and the front and rear side walls of the movable plate 16 are respectively fixed to the two sliding sleeves 14. Therefore, when the movable plate 16 is pushed by an external force, the two sliding sleeves 14 will be driven to move left and right along the rod body of the corresponding guide rod 15. The direction of movement of the movable plate 16 is guided, and the movable plate 16 is supported by two guide rods 15 so that the movable plate 16 can be overhung on the inner top of the sedimentation box 3; this scheme as a whole constitutes a support assembly for supporting and guiding the movable plate 16; of course, the support assembly can also adopt two sliders, and slide grooves for sliding of the two sliders are opened on the front and rear side walls of the sedimentation box 3, and the two sliders are respectively fixed to the movable plate 16, so that the movable plate 16 is supported and guided in the direction of movement by the cooperation of the sliders and the slide grooves.

Its structure is composed of a driving motor, a reduction gear, a screw, a nut, a guide sleeve, a push rod, a slide, a spring, a housing, a turbine, a micro-control switch and other tools. It can be considered as an extension of the structure of a rotating motor. The electric push rod is a new type of linear actuator mainly composed of a motor push rod and a control device and other mechanisms. The base of the electric push rod is fixed to the left side wall of the sedimentation box 3. A through hole is provided on the left side wall of the sedimentation box 3 for the telescopic end of the electric push rod to pass through. The end of the telescopic end of the electric push rod is fixed on the movable plate 16, so that the movable plate 16 is driven to move left and right in the sedimentation box 3 by the telescopic movement of the electric push rod.

[0031] The movable plate 16 is provided with a movable rod 18 that can move up and down. In this embodiment, the cross section of the movable rod 18 is a rectangular structure. The rectangular cross section of the movable rod 18 can prevent the movable rod 18 from rotating when moving up and down, thereby preventing the filter 20 from tilting and affecting the effect of cleaning oil and impurities. Of course, a structure other than a circular shape, such as a triangle, an ellipse, etc., can also be adopted.

A threaded hole for the screw to pass through and threadedly matched with the screw is opened on the left side wall of the movable plate 16. The screw is pressed against the surface of the movable rod 18, thereby locking the movable rod 18 after movement. Of course, the locking member can also be a positioning pin. A locking hole for the positioning pin to pass through is opened on the left side wall of the movable plate 16. Several positioning holes are opened at equal intervals along the rod body of the movable rod 18. When the movable rod 18 is moved to a suitable position, one end of the positioning pin is passed through the locking hole and installed in the positioning hole aligned with it, thereby locking the movable rod 18 after movement.

In this embodiment, the mounting frame 19 is fixed to the moving rod 18 by two screws. A mounting plate is fixed to the mounting frame 19. The mounting plate has two through holes for the two screws to pass through. The moving rod 18 has two threaded holes that are threadedly matched with the two screws, so that the mounting frame 19 is fixed to the moving rod 18 by the two screws. When the degreaser is precipitated, it contains impurities that are easy to float. When in use, the moving rod 18 is first moved up and down, thereby driving the mounting frame 19 and the filter 20 to move up and down. , immerse the lower half of the mounting frame 19 into the degreaser, and move the movable plate 16 left and right.

If the floating impurities are not cleaned in time, a thick layer of impurities will be attached to the inner wall of the sedimentation box 3 over time. After the impurities fall off, they will contaminate the degreaser, which will affect the quality of the degreaser precipitation and filtration over and over again.
