Description

Technical Field

[0001] This utility model relates to the field of rust removal equipment technology, and in particular to a metal surface treatment rust removal equipment. Background Technology

[0002] As basic components in industrial production, the surface condition of metal workpieces directly affects the assembly accuracy, performance and service life of products. During processing, storage and circulation, the surface of metal workpieces will inevitably rust due to oxidation, moisture and other factors. This is especially true for precision parts and complex structural parts. The presence of rust will lead to abnormal fit clearance and reduced connection strength, so rust removal equipment is needed to remove rust from metal parts.

[0003] Patent document CN221398076U discloses a rust removal device for metal materials, including a rust removal box. The rust removal box has a filter mechanism fixedly installed on one side for convenient rust removal agent filtration. A mesh screen is fixedly installed inside the rust removal box, and a support plate (L-shaped) is fixedly installed at the top. A pump body is fixedly installed at the top of the support plate, and a suction pipe is fixedly installed at the pump body's input end. One side of the suction pipe passes through the mesh screen and extends to the bottom of the rust removal box. This invention places a metal block at the top of the mesh screen. Rust removal agent inside the rust removal box removes rust from the outside of the metal block. The pump body is then activated, drawing in the rust removal agent through the suction pipe and discharging it into the filter mechanism. The rust removal agent inside the filter mechanism then flows back into the rust removal box through a return pipe, impacting the impeller and causing the stirring rod to rotate, agitating the rust removal agent. This allows the rust removal agent, which is currently far from the metal block, to come into contact with it, improving rust removal efficiency.

[0004] Existing equipment typically involves immersing the metal parts to be derusted in a derusting solution during use. However, the metal parts are usually stationary inside the derusting box. When a batch of metal parts enters the derusting box, they tend to overlap, making it difficult for the overlapped surfaces to come into contact with the derusting solution, thus affecting the derusting effect. Therefore, we propose a metal surface treatment derusting equipment. Utility Model Content

[0005] The main objective of this invention is to provide a metal surface treatment and rust removal device that can effectively solve the problems mentioned above.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A metal surface treatment rust removal device includes a housing and a filter box. The filter box is fixedly installed at the bottom of the housing. A placement box is horizontally slidably installed in the inner cavity of the housing. A pushing mechanism is provided between the front side of the inner cavity of the housing and the front side of the filter box. A buffer mechanism is provided between the filter box and the placement box. Sliding mechanisms are provided between the left and right sides of the inner cavity of the housing and the left and right sides of the placement box. A circulation mechanism is provided on the filter box, and the upper structure of the circulation mechanism extends into the upper part of the inner cavity of the placement box.

[0008] Preferably, the pushing mechanism includes a rotating shaft rotatably disposed on the front side of the housing, and two cams are fixedly disposed on the surface of the rotating shaft.

[0010] Preferably, a baffle is fixedly provided at the top edge of the inner cavity of the placement box.

[0011] Preferably, the sliding mechanism includes a slider and a slide rail. The slider is fixedly disposed on the left and right sides of the placement box, and the slide rail is fixedly disposed on the left and right side walls of the inner cavity of the box. The slider and the slide rail are slidably connected.

[0012] Preferably, the circulation mechanism includes an electric barrel-type liquid pump located on the left side of the filter box near the bottom. The input end of the electric barrel-type liquid pump is sealed and extends into the inner cavity of the filter box. The output end of the electric barrel-type liquid pump is sealed and equipped with an L-shaped delivery pipe. Multiple nozzles are evenly arranged on the surface of the delivery pipe parallel to the ground. The nozzles extend into the inner cavity of the box. The delivery pipe is fixed to the left side of the box by a fixing member. A column for supporting the delivery pipe is fixed between the right end of the nozzle and the right side of the top of the box.

[0013] Preferably, the top of the filter box has an open structure, and a filter plate is detachably installed on the upper part of the inner cavity of the filter box.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This device uses a designed pushing mechanism to place the workpiece to be derusted into the placement box. The pushing mechanism then moves the placement box back and forth, causing the basket itself, which is immersed in the liquid, to slowly and periodically sway or shake. This prevents the workpiece from stacking, forces the liquid to enter difficult-to-treat areas such as blind holes and crevices, and carries out reaction bubbles, significantly improving the uniformity and speed of derusting.

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Example 1, as Figures 1-5 As shown, a metal surface treatment rust removal device includes a housing 1 and a filter box 2, with the filter box 2 fixedly installed at the bottom of the housing 1.

[0025] A placement box 3 is horizontally slidably installed inside the inner cavity of the box body 1;

[0026] A pushing mechanism 4 is provided between the front side of the inner cavity of the housing 1 and the front side of the filter box 2;

[0027] A buffer mechanism 5 is provided between the filter box 2 and the placement box 3;

[0028] A sliding mechanism 6 is provided between the left and right sides of the inner cavity of the box 1 and the left and right sides of the placement box 3;

[0029] The filter box 2 is equipped with a circulation mechanism 7, and the structure above the circulation mechanism 7 extends into the upper part of the inner cavity of the placement box 3;

[0030] The placement box 3 is used to place the metal workpiece to be derusted, and the pushing mechanism 4 is used to push the filter box 2 to make horizontal reciprocating motion in the inner cavity of the box body 1 so that the placement box 3 makes a slow, periodic swing.

[0031] The inner cavity of the box 1 is filled with rust removal liquid for metal rust removal. The metal workpiece to be rusted is placed in the placement box 3, ensuring that the rust removal liquid level can completely submerge the metal workpiece subsequently placed in the placement box 3. Then, the pushing mechanism 4 pushes the placement box 3 to move back and forth, causing the material basket itself immersed in the liquid to slowly and periodically sway and shake, preventing the workpieces from stacking, forcing the liquid into difficult-to-treat areas such as blind holes and gaps, and bringing out reaction bubbles, which significantly improves the uniformity and speed of rust removal.

[0032] After soaking for the set time, the rust removal liquid in the box 1 is discharged into the filter box 2 below. After the rust removal liquid in the inner cavity of the box 1 is emptied, the liquid attached to the surface of the metal workpiece drips continuously into the bottom of the inner cavity of the box 1 through the through hole at the bottom of the placement box 3 to drain the metal parts. In conjunction with the pushing mechanism 4, the placement box 3 is driven to swing horizontally back and forth to accelerate the drainage process and prevent the rust removal liquid carried out by the metal parts from contaminating the subsequent operating environment.

[0033] After rust removal is completed, the circulation mechanism 7 is activated. The filtered soaking solution in the filter box 2 is transported back to the placement box 3 through the circulation mechanism 7 to prepare for the next soaking rust removal. This achieves filtration of the soaking solution, reduces or avoids the rust residue (iron oxide) and metal fragments that fall off during the rust removal process from being suspended or precipitated in the liquid and adsorbing the effective components of the rust remover, delaying the decrease in liquid concentration, and indirectly extending the service life of the rust remover solution.

[0034] In Example 2, in order to achieve the reciprocating swaying motion of the placement box 3, therefore, as follows: Figure 2 and Figure 3 As shown, the pushing mechanism 4 includes a rotating shaft 41 rotatably disposed on the front side of the housing 1, and two cams 42 are fixedly disposed on the surface of the rotating shaft 41.

[0035] The buffer mechanism 5 includes a telescopic rod 51 fixedly installed between the front and rear walls of the inner cavity of the box 1 and the front and rear walls of the placement box 3, and a spring 52 is provided on the surface of the telescopic rod 51.

[0036] The sliding mechanism 6 includes a slider 61 and a slide rail 62. The slider 61 is fixedly installed on the left and right sides of the placement box 3, and the slide rail 62 is fixedly installed on the left and right side walls of the inner cavity of the box 1. The slider 61 and the slide rail 62 are slidably connected.

[0037] When the equipment needs to be used to make the placement box 3 swing and shake, the motor is started. Since the motor is fixedly connected to the right end of the rotating shaft 41 and fixedly installed on the box body 1, it drives the rotating shaft 41 to rotate at low speed.

[0038] Two cams 42 are fixedly installed on the surface of the rotating shaft 41. The two cams 42 are symmetrically distributed around the rotating shaft 41, and their outlines are both non-circular eccentric structures. When the rotating shaft 41 rotates, it will drive the two cams 42 to rotate synchronously.

[0039] Due to the eccentricity of cam 42, during rotation, the outer edge of cam 42 will periodically contact the front side of the placement box 3 and generate a thrust. When the long diameter end of cam 42 turns towards the placement box 3, it will apply a backward thrust to the placement box 3, forcing the placement box 3 to overcome the elastic force of spring 52 in buffer mechanism 5 and slide backward along slide rail 62 of sliding mechanism 6.

[0040] When the short-diameter end of cam 42 turns towards the placement box 3, the thrust of cam 42 on the placement box 3 disappears. At this time, the compressed spring 52 in the buffer mechanism 5 will release elastic potential energy, pushing the placement box 3 to slide forward along the slide rail 62 and return to the vicinity of the initial position.

[0041] This cycle repeats continuously. Driven by the continuous rotation of the rotating shaft 41, the two cams 42 alternately apply and release the thrust to the placement box 3. Combined with the reset function of the buffer mechanism 5, the placement box 3 eventually achieves slow, periodic reciprocating swaying within the cavity of the box body 1, preventing workpieces from stacking. This allows the metal workpieces inside the placement box 3 to come into more full contact with the rust removal liquid sprayed by the circulation mechanism 7, thereby improving the rust removal effect.

[0042] In Example 3, to prevent internal liquid from overflowing when the box 1 is swaying and shaking, therefore, as follows: Figures 1-5 As shown, a baffle 31 is fixedly installed on the top edge of the inner cavity of the placement box 3;

[0043] When the placement box 3 is swayed, the rising liquid level caused by the shaking inside will be blocked by the baffle 31, preventing the liquid from overflowing beyond the edge of the placement box 3 and wasting the rust removal liquid, thus further improving the stability and safety of the equipment operation.

[0044] Example 4: To achieve the recycling of the rust removal fluid and the filtration of impurities, therefore, as follows... Figures 1-5 As shown, the circulation mechanism 7 includes an electric barrel pump 71 located on the left side of the filter box 2 near the bottom. The input end of the electric barrel pump 71 is sealed and extends into the inner cavity of the filter box 2. The output end of the electric barrel pump 71 is sealed and equipped with an L-shaped delivery pipe 72. Multiple nozzles 73 are evenly arranged on the surface of the delivery pipe 72 parallel to the ground. The nozzles 73 extend into the inner cavity of the placement box 3. The delivery pipe 72 is fixed to the left side of the box body 1 by a fixing member 74. A column 75 for supporting the delivery pipe 72 is fixed between the right end of the nozzle 73 and the top right side of the box body 1.

[0045] The top of the filter box 2 has an open structure, and a filter plate 21 is detachably installed on the upper part of the inner cavity of the filter box 2;

[0046] A drain pipe 11 is provided on one side of the bottom of the housing 1, and the drain pipe 11 is located above the filter plate 21;

[0047] After soaking for the set time, the drain pipe 11 is opened by controlling the valve. The rust removal liquid in the inner cavity of the box 1 is discharged into the filter box 2 through the drain pipe 11 at the bottom to drain the metal parts and prevent the rust removal liquid carried out by the metal parts from contaminating the subsequent operating environment.

[0048] The rust removal liquid entering the filter box 2 flows to the bottom of the inner cavity of the filter box 2 after the impurities are filtered by the filter plate 21. After the metal parts are rusted and removed from the placement box 3, the electric barrel pump 71 is started. Its input end is sealed and extends into the inner cavity of the filter box 2 to extract the filtered rust removal liquid. Then it is transferred through the L-shaped delivery pipe 72 which is sealed to the output end of the electric barrel pump 71.

[0049] Multiple nozzles 73, evenly distributed on the surface of the delivery pipe 72 parallel to the ground, extend into the inner cavity of the placement box 3. Under the pressure of the electric barrel pump 71, the rust removal liquid is evenly sprayed into the placement box 3 through the nozzles 73, preparing for the next soaking rust removal. This filters the soaking liquid, reducing or preventing rust residue (iron oxide) and metal fragments that fall off during the rust removal process from suspending or settling in the liquid and adsorbing the effective components of the rust removal agent, thus delaying the decrease in liquid concentration and indirectly extending the service life of the rust removal liquid.

[0050] In addition, the electric tank pump 71 can adapt to most rust removal liquids ranging from low to medium viscosity and from general to strong corrosion, meeting the needs of over 80% of application scenarios. Whether it is a common medium or various strong acids, alkalis, flammable and explosive rust removal liquids, it can deliver them safely and efficiently.

[0051] In specific use, the inner cavity of the box 1 is filled with rust remover for metal rust removal. The metal workpiece to be rusted is placed in the placement box 3, ensuring that the rust remover liquid level can completely submerge the metal workpiece subsequently placed in the placement box 3.

[0052] Next, start the motor. Since the motor is fixedly connected to the right end of the rotating shaft 41 and fixedly installed on the housing 1, it drives the rotating shaft 41 to rotate at a low speed.

[0053] Two cams 42 are fixedly installed on the surface of the rotating shaft 41. The two cams 42 are symmetrically distributed around the rotating shaft 41, and their outlines are both non-circular eccentric structures. When the rotating shaft 41 rotates, it will drive the two cams 42 to rotate synchronously.

[0054] Due to the eccentricity of cam 42, during rotation, the outer edge of cam 42 will periodically contact the front side of the placement box 3 and generate a thrust. When the long diameter end of cam 42 turns towards the placement box 3, it will apply a backward thrust to the placement box 3, forcing the placement box 3 to overcome the elastic force of spring 52 in buffer mechanism 5 and slide backward along slide rail 62 of sliding mechanism 6.

[0055] When the short-diameter end of cam 42 turns towards the placement box 3, the thrust of cam 42 on the placement box 3 disappears. At this time, the compressed spring 52 in the buffer mechanism 5 will release elastic potential energy, pushing the placement box 3 to slide forward along the slide rail 62 and return to the vicinity of the initial position.

[0056] In this cycle, driven by the continuous rotation of the rotating shaft 41, the two cams 42 alternately apply and release the thrust to the placement box 3. With the reset action of the buffer mechanism 5, the placement box 3 eventually achieves slow, periodic reciprocating swaying within the cavity of the box body 1.

[0057] When the placement box 3 is shaken, the rising liquid level caused by the shaking will be blocked by the baffle 31 to prevent the liquid from overflowing over the edge of the placement box 3.

[0058] After soaking for the set time, the drain pipe 11 is opened by controlling the valve, and the rust removal liquid in the inner cavity of the box 1 is discharged into the filter box 2 through the drain pipe 11 at the bottom to drain the metal parts.

[0059] The rust-removing liquid entering the filter box 2 flows to the bottom of the inner cavity of the filter box 2 after impurities are filtered by the filter plate 21. After the metal parts are derusted and removed from the placement box 3, the electric barrel pump 71 is started. Its input end is sealed and extends into the inner cavity of the filter box 2 to extract the filtered rust-removing liquid. Then, it is transmitted through the L-shaped delivery pipe 72, which is sealed and connected to the output end of the electric barrel pump 71. Multiple nozzles 73, which are evenly distributed on the surface of the delivery pipe 72 parallel to the ground, extend into the inner cavity of the placement box 3. Under the pressure of the electric barrel pump 71, the rust-removing liquid is evenly sprayed into the placement box 3 through the nozzles 73, in preparation for the next soaking rust removal.

[0060] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
