Description

Technical Field

[0001] This invention relates to the field of steel surface treatment technology, specifically to a hot-dip galvanizing equipment for steel surfaces in steel structure processing. Background Technology

[0002] Hot-dip galvanizing is a widely used process for anti-corrosion treatment of steel surfaces. It involves immersing cleaned steel in molten zinc, forming a dense zinc layer on the steel surface to achieve corrosion resistance and extend service life. Due to its strong coating adhesion and good anti-corrosion effect, this process is widely used in construction, transportation, energy, and other fields. However, traditional hot-dip galvanizing equipment and processes have several problems, including: the zinc liquid and steel are relatively static, resulting in relatively low fluidity between them; and the steel is often stored in containers, leading to numerous obscured areas on the steel surface, preventing comprehensive galvanizing and creating galvanizing dead zones. Furthermore, the relatively slow contact speed between the zinc liquid and the steel surface hinders galvanizing efficiency, thus affecting the overall production efficiency of steel galvanizing. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention is implemented through the following technical solution: a hot-dip galvanizing equipment for steel structure processing, comprising a box body, a hanger fixedly installed on the top inner side of the box body, an inlet / outlet pipe body installed through the left front end of the box body for the steel to enter and exit the box body, a ventilation assembly installed on the side wall of the box body for ventilation of the box body, a lifting cylinder installed on the inner side of the box body below the hanger, a hot-dip galvanizing tank installed directly below the lifting cylinder, an attachment hopper installed on the outer surface of the hot-dip galvanizing tank near the top, and the inlet / outlet pipe body passing through the box body. The hopper is longitudinally aligned with the hopper body to facilitate the removal of galvanized steel. A lead screw is installed on the side of the hanger away from the top plate of the box. The right end of the lead screw passes through the hanger and is connected to a first servo motor. The lead screw is rotatably mounted to the hanger via the first servo motor. Two electric lifting rods, namely electric lifting rod one and electric lifting rod two, are installed side by side on the lead screw. Electric lifting rod one is symmetrically installed with respect to electric lifting rod two, and there are only one electric lifting rod one. Both electric lifting rod one and electric lifting rod two have spline heads installed on their flanges. The spline heads are threaded onto the lead screw. A stirring motor is installed on the flange of the telescopic end of electric lifting rod two.

[0004] A hinged door is attached to one side of the lifting cylinder. A base plate is installed at the bottom of the lifting cylinder. The top of the base plate has a circular array of spiral bevels, which are counterclockwise. A circular array of through holes is also present on the top of the base plate. This design, connecting the through holes to the spiral bevels, facilitates the rapid passage of molten zinc, accelerating its entry into the lifting cylinder. Furthermore, after the galvanizing operation is completed, when the lifting cylinder is raised from the inside of the hot-dip galvanizing tank, the through holes allow for easy removal of most of the molten zinc. The zinc liquid is rapidly drained, reducing the amount of zinc residue. The through-hole penetrates the chassis component and is opened in the middle of the spiral bevel and connected to the spiral bevel. The top of the chassis component is fixedly installed with convex spheres in a circular array, and the convex spheres are installed around the spiral bevel. The edges where the spiral bevel and the through-hole penetrate the chassis component are all equipped with rounded parts. By setting the rounded parts, the sharp edges of the parts with holes on the top of the chassis component can be eliminated, eliminating the risk of the chassis component scratching the steel surface and reducing the risk of damage to the steel before and after galvanizing.

[0005] Preferably, the hanger is surrounded by a protective box around the first servo motor, which is used to isolate and protect the first servo motor. A central straight rail is fixedly installed in the middle of the side of the hanger facing the spline head.

[0006] Preferably, a crescent-shaped filter bucket is fitted inside the inner side of the hopper body and on the side near the hot-dip galvanizing tank. Filter holes are provided on both the side of the hopper body near the hot-dip galvanizing tank and the surface of the crescent-shaped filter bucket. The filter holes are used to filter and guide the zinc liquid into the hot-dip galvanizing tank. The outer diameter of the hanging cylinder is equal to the inner radius of the hot-dip galvanizing tank.

The chassis component is elastically installed with the lifting cylinder through the cooperation of the tension spring and the clamping rods. The corrugated hose is used to block waste residue outside the clamping rods and the tension spring, ensuring the normal use of the clamping rods and the tension spring, and ensuring that the lifting cylinder can perform vertical elastic movement with the chassis component through the installation relationship between the above structures.

[0010] Preferably, the bottom side of the hot-dip galvanizing tank is connected to support legs in a circular array, and the support legs are inserted into the bottom plate of the tank. A right-angle bracket is bolted to the outer surface of the hot-dip galvanizing tank and the side near the hopper. The right-angle bracket is installed directly below the hopper through the hot-dip galvanizing tank to provide support for the bottom of the hopper. A hydraulic push rod is installed in the middle of the bottom of the hot-dip galvanizing tank. A piston disc is installed in the middle of the inner side of the hot-dip galvanizing tank. The telescopic end of the hydraulic push rod passes through the hot-dip galvanizing tank and is connected to the piston disc. The piston disc is lifted and lowered by the hot-dip galvanizing tank through the hydraulic push rod.

[0011] Preferably, the bottom of the piston disc is connected to guide rods in a circular array, and the guide rods pass through the hot-dip galvanizing tank and the support leg insert.

[0013] Preferably, the output end of the stirring motor is connected to a long shaft via a coupling, and a blade is installed on the long shaft via a pin.

A washer spring is connected to the bottom of the sliding sleeve, and the washer spring is fitted with the long shaft via the sliding sleeve.

[0014] This invention provides a hot-dip galvanizing equipment for steel surfaces in steel structure processing, which has the following beneficial effects:

[0015] 1. The hot-dip galvanizing equipment for the steel structure processing involves activating the second electric lifting rod to return the paddle to its initial position. Simultaneously, the first and second electric lifting rods slowly lower the lifting cylinder and chassis, immersing them in the molten zinc. During this process, the molten zinc enters the inner side of the lifting cylinder and chassis through the spiral oblique opening, the straight through-hole, and the annular gap between the lifting cylinder and the chassis, contacting the steel. Once the molten zinc has completely submerged the steel surface, the stirring motor can be activated again to... The blades rotate counterclockwise in the molten zinc, causing the zinc to flow counterclockwise inside the hot-dip galvanizing tank. This counterclockwise flow propels the molten zinc into the hanging cylinder and chassis components through the spiral oblique opening and straight through-hole, improving the fluidity between the molten zinc and the steel, increasing the contact area between them, eliminating dead zones, and accelerating the contact speed between the molten zinc and the steel surface. This improves the efficiency of the equipment in galvanizing steel, thereby increasing the production efficiency of the equipment in galvanizing steel.

[0016] II. The hot-dip galvanizing equipment for the steel surface of this steel structure, by activating the electric lifting rod II, performs periodic extension and retraction movements within the effective elastic range of the washer spring. This drives the paddle on the long rod shaft to repeatedly squeeze the washer spring, and the washer spring gently pushes the chassis component, causing periodic lifting and lowering movements between the chassis component and the lifting cylinder. This allows the steel to move up and down relative to the zinc liquid, and also in the vertical direction, further increasing the contact area between the steel and the zinc liquid, further expanding the fluidity between the zinc liquid and the steel, further eliminating dead zones in the galvanizing process, and also accelerating the galvanizing process of the steel.

[0017] Third, the hot-dip galvanizing equipment for the steel structure processing utilizes paddles and washers and springs to drive the vertical movement between the chassis and the lifting cylinder. The washers and springs act as elastic buffers, preventing the weight of the chassis from directly impacting the paddles and protecting their normal operation. Simultaneously, the clamping rod on the chassis and the tension spring connected to it allow the chassis to move up and down within a small range relative to the bottom of the lifting cylinder. This prevents the steel from being shaken out and guides some of the waste generated during galvanizing into the hot-dip galvanizing tank through spiral bevels, straight through-holes, and the annular gap between the chassis and the lifting cylinder. This avoids waste production affecting the overall galvanizing effect, prevents waste from obscuring the steel surface, prevents galvanizing defects, and improves the galvanizing quality of the steel surface.

[0018] Fourth, the hot-dip galvanizing equipment for the steel structure processing can protect the tension spring and the clamp rod by using corrugated hoses installed in a wrapping shape around them. This prevents waste residue from adhering to or clogging the tension spring and the clamp rod, and also prevents unnecessary adhesion and waste of molten zinc on the surface of the tension spring and the clamp rod. This avoids unnecessary cost waste caused by molten zinc entering the clamp cavity, saving production costs while ensuring smooth up-and-down movement between the chassis and the lifting cylinder.

[0019] V. The hot-dip galvanizing equipment for steel structures utilizes several convex spheres mounted on the top of the chassis to provide a series of point-like horizontal support planes for the placement of the steel on the top of the chassis. This elevates the steel from the top of the chassis, facilitating the contact between the molten zinc and the bottom of the steel during immersion in the zinc solution. This prevents blockage of the zinc solution's entry point from the bottom of the chassis to the top, and also eliminates the close contact between the top of the chassis and the bottom of the steel, reducing the area of ​​the steel surface obscured and increasing the effective galvanized area. Furthermore, the frictionless curved surface of the convex spheres facilitates the sliding and removal of the steel from the top of the chassis, whether by direct gripping or sliding it out from the inside of the lifting cylinder. This reduces the risk of wear and tear on the steel from the chassis and avoids the risk of scratches and damage to the galvanized layer of the steel surface caused by the equipment.

The spline head 8 is slidably installed with the hanger 2 through the straight rail 21. The top of the spline head 8 is fitted and limited to the bottom of the hanger 2 by the straight rail 21 to prevent the hanging cylinder 3, which is suspended below the hanger 2 by the electric lifting rod 1 6 and the electric lifting rod 2 7, from swaying left and right.

[0037] The top of the lifting cylinder 3 is centrally symmetrically fixed with a lifting block 33, and the top of the lifting block 33 is installed with the extension flange of the electric lifting rod 6. The lifting cylinder 3 is lifted and installed with the lifting frame 2 through the cooperation of the electric lifting rod 6 and the lifting block 33.

The chassis component 32 is elastically installed with the lifting cylinder 3 through the cooperation of the tension spring 302 and the clamping rods 321. The corrugated hose 303 is used to block the waste residue outside the clamping rods 321 and the tension spring 302, ensuring the normal use of the clamping rods 321 and the tension spring 302, and ensuring that the lifting cylinder 3 can move elastically in the vertical direction with the chassis component 32 through the installation relationship between the above structures.

[0040] The bottom side of the hot-dip galvanizing tank 4 is connected with support legs 41 in a circular array, and the support legs 41 are inserted into the bottom plate of the tank body 1. A right-angle bracket 42 is bolted to the outer surface of the hot-dip galvanizing tank 4 and the side near the attached bucket 5. The right-angle bracket 42 is installed directly below the attached bucket 5 through the hot-dip galvanizing tank 4 to provide support for the bottom of the attached bucket 5. A hydraulic push rod 43 is installed in the middle of the bottom of the hot-dip galvanizing tank 4. A piston disc 44 is installed in the middle of the inner side of the hot-dip galvanizing tank 4. The telescopic end of the hydraulic push rod 43 passes through the hot-dip galvanizing tank 4 and is connected to the piston disc 44. The piston disc 44 is lifted and lowered by the hot-dip galvanizing tank 4 through the hydraulic push rod 43.

[0041] The bottom of the piston disc 44 is connected to guide rods 45 in a circular array, and the guide rods 45 are inserted through the hot-dip galvanizing tank 4 and the support leg 41. The guide rods 45 are used to assist in guiding the smooth lifting and lowering movement of the piston disc 44 inside the hot-dip galvanizing tank 4 in conjunction with the hydraulic push rod 43.

[0042] The output end of the stirring motor 11 is connected to a long shaft 111 via a coupling. A blade 112 is mounted on the long shaft 111 via a pin. The blade 112 is mounted on the bottom of the chassis component 32 via the long shaft 111. The blade 112 is rotatably mounted with the chassis component 32 via the long shaft 111, the sliding sleeve 34 and the stirring motor 11. A washer spring 113 is connected to the bottom of the sliding sleeve 34, and the washer spring 113 is fitted with the long shaft 111 via the sliding sleeve 34.

[0043] In use, the initial position of the hoisting cylinder 3 is: suspended in the middle of the upper part of the attached bucket body 5; the piston disc 44 is attached to the bottom plate of the hot-dip galvanizing tank 4, the semi-circular spring piece 48 is embedded in the inner wall of the hot-dip galvanizing tank 4, and the scrap pipe 46 is closed; an appropriate amount of zinc liquid is conveyed into the inside of the hot-dip galvanizing tank 4 through the feed pipe 47; at this time, the pin rod 35 is pulled out to open the movable door 31, and the steel is neatly placed into the inside of the hoisting cylinder 3 through the feed pipe body 12, and then the movable door 31 is closed, so that the movable door 31 and the hoisting cylinder 3 form a complete cylindrical closed structure, and then the pin rod 35 is re-inserted into the other side of the movable door 31 and the hoisting cylinder 3 (non-hinged), locking the movable door 31 onto the hoisting cylinder 3; then the first servo motor 9 is activated to drive the lead screw 10 to rotate counterclockwise on the hanger 2, so that the spline head 8 is guided along the straight rail 21, and the scrap pipe 46 is electrically driven to rotate the lead screw 10. The lifting rod 6 and the electric lifting rod 7 work together to move the lifting cylinder 3 horizontally towards the right end near the first servo motor 9 until the lifting cylinder 3 is directly above the hot-dip galvanizing tank 4. Then, the electric lifting rod 6 and the electric lifting rod 7 are simultaneously extended to lower the lifting cylinder 3 into the inside of the hot-dip galvanizing tank 4, so that the steel is completely immersed in the molten zinc and a dense zinc layer is formed on the surface of the steel. After the steel is galvanized, the electric lifting rod 6 and the electric lifting rod 7 are simultaneously raised and the same operating steps are used to return the lifting cylinder 3 to its initial position, that is, the lifting cylinder 3 is suspended directly above the bucket body 5 by the lifting frame 2. At this time, the galvanized steel can be taken out, and the above operation is repeated to galvanize the next batch of steel. This cyclical operation is used to galvanize the surface of a large number of steel products.

[0044] When the lifting cylinder 3 returns to its initial position, the electric lifting rod 7 is retracted, driving the long shaft 111 connected to the bottom of the stirring motor 11. The blades 112 on the long shaft 111 are vertically retracted to vertically compress the pad spring 113 at the bottom of the sliding sleeve 34, causing an elastic collision with the bottom of the chassis 32. This causes the chassis 32 and the lifting cylinder 3 to shake vertically, quickly shaking off the zinc liquid residue remaining on the lifting cylinder 3 and the chassis 32 into the hopper 5. This prevents the zinc liquid from spilling outside the hot-dip galvanizing tank 4 or the hopper 5 as the steel is removed, thus avoiding zinc liquid contamination of the inside of the tank 1 and unnecessary cleaning work.

[0045] At the same time, this shaking action can also be used to shake off the residual waste residue into the hopper 5, and the hopper 5 can be used to collect and store the waste residue separately, reducing the total amount of waste residue accumulated inside the hot-dip galvanizing tank 4 and eliminating some of the interference of waste residue on the steel during the galvanizing process inside the hot-dip galvanizing tank 4.

[0046] Simultaneously activating electric lifting rod 6 and electric lifting rod 7, before lowering the hoisting cylinder 3 into the hot-dip galvanizing tank 4 for galvanizing, the electric lifting rod 7 can be used alone to drive the paddle 112 mounted on the long rod shaft 111 to pre-enter the zinc liquid inside the hot-dip galvanizing tank 4, so that the paddle 112 reaches the middle of the zinc liquid. Then, by activating the stirring motor 11, the paddle 112 on the long rod shaft 111 is driven to rotate clockwise in the zinc liquid to stir it evenly, so that all components in the zinc liquid can be evenly distributed in the hot-dip galvanizing tank 4. This provides a pre-treatment of the zinc liquid for galvanizing the steel surface, ensuring the quality of galvanizing on the steel surface.

[0047] Then, the stirring motor 11 is turned off, and the electric lifting rod 7 is activated to drive the blade 112 back to its initial position. Simultaneously, the electric lifting rods 6 and 7 are activated to slowly lower the cylinder 3 and chassis 32, allowing them to slowly sink into the molten zinc. During this process, the molten zinc enters the inner side of the cylinder 3 and chassis 32 through the spiral oblique opening 322, the straight through hole 323, and the annular gap between the cylinder 3 and chassis 32, contacting the steel. Once the molten zinc has submerged the entire steel surface, the stirring motor 11 can be activated again to drive the blade 112 back to its initial position. The blade 112 rotates counterclockwise in the zinc liquid to stir it, causing the zinc liquid to flow counterclockwise inside the hot-dip galvanizing tank 4. This counterclockwise flow propels the zinc liquid entering the hanging cylinder 3 and the chassis 32 through the spiral oblique opening 322 and the straight through hole 323, improving the fluidity between the zinc liquid and the steel, increasing the contact area between the zinc liquid and the steel, eliminating dead corners between the zinc liquid and the steel, and accelerating the contact speed between the zinc liquid and the steel surface. This improves the efficiency of the equipment in galvanizing the steel surface, thereby increasing the production efficiency of the equipment in galvanizing steel.

[0048] During this period, the electric lifting rod 7 can be activated to perform periodic extension and retraction within the effective range of motion of the washer spring 113. This causes the blade 112 on the long rod shaft 111 to repeatedly compress the washer spring 113. The washer spring 113 then gently pushes the chassis component 32, causing periodic lifting and lowering between the chassis component 32 and the lifting cylinder 3. This allows the steel to move up and down in the vertical direction relative to the molten zinc, further increasing the contact area between the steel and the molten zinc, further expanding the fluidity between the molten zinc and the steel, further eliminating dead angles in the galvanizing process, and accelerating the galvanizing process of the steel.

[0049] When the blade 112 moves vertically between the chassis 32 and the lifting cylinder 3 with the help of the washer spring 113, the washer spring 113 acts as an elastic buffer, avoiding the direct impact of the weight borne by the chassis 32 on the blade 112 and protecting the normal use of the blade 112. At the same time, the clamping rod 321 on the chassis 32 and the tension spring 302 connected to the chassis 32 allow the chassis 32 to move up and down within a small range in the vertical direction relative to the bottom of the lifting cylinder 3. This prevents the steel from being shaken out and allows some of the waste slag generated during the galvanizing process to be guided into the hot-dip galvanizing tank 4 through the spiral oblique opening 322, the straight through hole 323 and the annular gap between the chassis 32 and the lifting cylinder 3. This avoids the production of waste slag from affecting the overall galvanizing effect of the steel, prevents waste slag from causing large-area obstruction on the surface of the steel, prevents the appearance of galvanizing defects on the steel surface, and improves the galvanizing quality of the steel surface.

[0050] During this period, the corrugated hose 303, which is installed around the tension spring 302 and the clamp rod 321 in a wrapping manner, can be used to protect the two structures mentioned above, preventing waste residue from adhering to or clogging the tension spring 302 and the clamp rod 321. It also prevents unnecessary adhesion and waste of zinc liquid on the surface of the tension spring 302 and the clamp rod 321, avoiding unnecessary cost waste caused by zinc liquid entering the clamp cavity 301. While saving production costs, it can also ensure smooth up and down bouncing movement between the chassis component 32 and the lifting cylinder 3.

[0051] The convex spheres 324 installed on the top of the chassis component 32 provide a series of point-like horizontal support planes for the placement of steel on the top of the chassis component 32. This allows the steel to be lifted and moved from the top of the chassis component 32, facilitating the contact between the molten zinc and the bottom of the steel during immersion in zinc liquid. This prevents blockage of the inlet for the molten zinc to enter the top of the chassis component 32 from the bottom, and also eliminates the need for additional support. The close contact between the top and the bottom of the steel reduces the area of ​​the steel surface that is obscured, increases the effective area of ​​the steel surface that is galvanized, and at the same time, when the steel is removed later, the frictionless properties of the curved surface of the convex sphere 324 facilitate the sliding and removal of the steel on the top of the chassis component 32. Whether the steel is directly grabbed or pushed out from the inside of the lifting cylinder 3, the wear and tear of the chassis component 32 on the steel is reduced, and the risk of scratches and damage to the galvanized layer on the steel surface is avoided.

[0052] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figure 4As shown, a crescent-shaped filter hopper 51 is fitted into the inner side of the hopper body 5 and the side near the hot-dip galvanizing tank 4. Filter holes are provided on the side of the hopper body 5 near the hot-dip galvanizing tank 4 and on the surface of the crescent-shaped filter hopper 51 for filtering the zinc liquid collected inside the hopper body 5. The filter holes are used to guide the zinc liquid into the hot-dip galvanizing tank 4. The outer diameter of the hanging cylinder 3 is equal to the inner radius of the hot-dip galvanizing tank 4, which facilitates the movement of the hanging cylinder 3 within a small range inside the hot-dip galvanizing tank 4 and provides effective space for the zinc liquid to fully contact the steel. The transverse axis length and longitudinal width of the hopper body 5 are both greater than the outer diameter of the hanging cylinder 3 to prevent the zinc liquid from spilling outside the hopper body 5 during the zinc plating process.

[0053] In use, the attached hopper 5 can also serve as a horizontal extension and expansion of the receiving space of the hot-dip galvanizing tank 4, providing an independent static drainage area for the steel after galvanizing. It can shake off the zinc liquid remaining on the steel, the hanging cylinder 3, and the chassis 32, while also shaking off some of the waste residue generated during galvanizing into the attached hopper 5 for separate collection. Through the double filtration effect of the crescent-shaped filter 51 and the contact area between the attached hopper 5 and the hot-dip galvanizing tank 4, this part of the residual zinc liquid can be recycled and reused. This part of the zinc liquid can be directly guided back into the hot-dip galvanizing tank 4 through the attached hopper 5, avoiding unnecessary loss of zinc liquid. At the same time, under the thrust of the zinc liquid flowing into the hot-dip galvanizing tank 4, the attached hopper 5 helps to collect the waste residue inside the crescent-shaped filter 51, so that the waste residue can be removed from the attached hopper 5 later, facilitating quick and easy treatment of this part of the waste residue.

[0054] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figure 5 As shown, a scrap pipe 46 is connected to the outer surface of the hot-dip galvanizing tank 4 on the side away from the right-angle bracket 42. A feed pipe 47 is installed directly above the scrap pipe 46 and is fixedly connected to the hot-dip galvanizing tank 4. A semi-circular spring piece 48 is fitted and installed on the inner surface of the hot-dip galvanizing tank 4 on the side near the right-angle bracket 42. The semi-circular spring piece 48 is made entirely of elastic material and has deformation and rebound properties. Both ends of the semi-circular spring piece 48 away from the right-angle bracket 42 are hinged to the hot-dip galvanizing tank 4. A worm gear 49 is rotatably connected to the center of the side of the plate 48 facing the right-angle bracket 42, and the worm gear 49 passes through the hot-dip galvanizing tank 4 and is threadedly installed on the right-angle bracket 42. A second servo motor 410 is fixedly installed on the right-angle bracket 42, and a worm wheel 411 is installed on the output end of the second servo motor 410. The worm wheel 411 meshes with the worm gear 49. The semi-circular spring plate 48 is scraped and installed on the top of the piston disc 44 through the cooperation of the worm wheel 411 on the second servo motor 410 and the worm gear 49 on the right-angle bracket 42.

[0055] After the equipment is shut down, the molten zinc in the hot-dip galvanizing tank 4 can be left to stand for a period of time. Then, the clean upper layer of molten zinc can be extracted, and the hydraulic push rod 43 can be used to raise the piston disc 44. Under the vertical guidance of the guide rod 45, the top of the piston disc 44 rises to a position where it is flush with the bottom of the semi-circular spring piece 48. Figure 5 As shown; then the waste pipe 46 is opened to release and collect the remaining liquid for processing. Then, the second servo motor 410 is activated, using the meshing transmission of the worm gear 411 and worm 49 to drive the worm 49, guided by the right-angle bracket 42, to extend into the inside of the hot-dip galvanizing tank 4. This pushes the semi-circular spring piece 48, which is fitted into the inner wall of the hot-dip galvanizing tank 4, towards the waste pipe 46. The semi-circular spring piece 48 acts as a scraper, collecting the waste residue remaining on the piston disc 44 near the waste pipe 46, thus assisting the operator. The equipment assists in collecting and processing the waste residue inside the hot-dip galvanizing tank 4, accelerating the cleaning efficiency of the tank. At the same time, it lifts the waste residue at the bottom of the hot-dip galvanizing tank 4 to the middle of the tank, saving the operator half of the cleaning space. The waste residue is then lifted and collected near the waste pipe 46 for easy discharge, thus realizing the equipment's easy-to-clean function, saving cleaning and maintenance time, and improving the equipment's practicality and self-cleaning efficiency.
