DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] refer to Figure 1-Figure 7 This embodiment provides a surface treatment device for waste materials used in metal processing, including a processing box 100, an outer frame 101, an inner frame 102, a partition 103, a conveying pipe 106, a conveying component, a shaking component and a sand washing component.

[0022] Specifically, the processing chamber 100 is provided with a slidable outer frame 101, and an inner frame 102 is provided inside the outer frame 101 to hold the metal workpiece to be processed. The outer frame 101 is mounted within the processing chamber 100 via track grooves 204 and can move back and forth vertically, thereby driving the workpiece up and down during the processing process, enhancing the cleaning effect.

[0023] A horizontal partition 103 is installed in the lower middle portion of the treatment chamber 100, dividing the interior into two upper and lower sections: an upper cleaning chamber 104 and a lower sand chamber 105. Sand chamber 105 is filled with a certain amount of sand and gravel, which serves as a cleaning medium. A liquid outlet pipe 109 is connected to the sand chamber 105 to discharge oily waste liquid accumulated during the cleaning process. A liquid inlet pipe 108 is installed above the cleaning chamber 104 to inject cleaning liquid (such as an alkaline aqueous solution or degreaser).

[0024] Multiple conveying pipes 106 extend through the partition 103 from the sand cavity 105 to the top of the outer frame 101. Each conveying pipe 106 is equipped with a spiral dragon 107, one end of which is located within the sand cavity 105 and the other end is located at the discharge port at the top of the outer frame 101. Driven by a conveying component, the conveying pipes 106 transport the sand from the sand cavity 105 to the inner frame 102 within the outer frame 101, allowing the sand to come into contact with the metal workpiece to be cleaned.

[0025] In order to achieve an efficient cleaning effect, a shaking component is provided between the delivery pipe 106 and the outer frame 101. The shaking component drives the delivery pipe 106 to move back and forth in the horizontal direction while causing the outer frame 101 to move back and forth in the vertical direction.

[0026] In addition, a sand washing component is installed between the partition 103 and the delivery pipe 106. This component can control the intermittent opening and closing of the partition 103. When the delivery pipe 106 moves in direction a (i.e., toward the outer frame 101), the partition 103 is closed and the sand in the sand cavity 105 is disturbed. When the delivery pipe 106 moves in direction b (i.e., away from the outer frame 101), the partition 103 is opened and the sand in the sand cavity 105 is disturbed.

[0027] With this setup, the workpiece to be cleaned can be placed into the inner frame 102, which is then placed inside the outer frame 101, where it is received. After the device is activated, the liquid inlet pipe 108 at the top of the processing box 100 begins to inject cleaning fluid (such as an alkaline aqueous solution or a degreaser) into the cleaning chamber 104. The fluid flows over the workpiece surface, softening oil stains and suspending fine debris. Simultaneously, the oily waste liquid generated during the cleaning process is discharged through the liquid outlet pipe 109 at the bottom of the sand chamber 105, preventing waste liquid from accumulating and affecting the cleaning effect.

[0028] The sand filling the sand cavity 105 is transported to the top of the outer frame 101 via spiral dragons 107 within multiple delivery pipes 106. The sand then falls into the inner frame 102, where it comes into contact with the metal workpiece. The conveying components are continuously driven, circulating the sand onto the workpiece surface. The sand particles exert multi-point, multi-directional mechanical friction on the workpiece surface, effectively removing stubborn oil stains, metal debris, and oxide layers. This sand friction cleaning process offers greater decontamination power than single-liquid cleaning or brushing methods, significantly improving workpiece surface cleanliness and ensuring the quality of subsequent recycling or processing.

[0029] Furthermore, a rocking element is installed between the delivery tube 106 and the outer frame 101, driving the delivery tube 106 in horizontal reciprocating motion while the outer frame 101 reciprocates vertically. The workpiece constantly changes its posture and force direction during cleaning, ensuring that the sand rolls more evenly and thoroughly across the workpiece surface. This multi-dimensional, coordinated design significantly improves cleaning comprehensiveness and efficiency.

[0030] To ensure the cleanliness and recycling of the sand, a sand washing unit is installed between baffle 103 and delivery pipe 106, which is used to intermittently open and close baffle 103. When delivery pipe 106 moves in direction b, baffle 103 opens, allowing the sand that falls from above baffle 103 to fall smoothly back into sand chamber 105. Simultaneously, the movement of delivery pipe 106 continuously agitates the sand within sand chamber 105, causing it to collide and tumble with each other, and friction strips away oil and fine debris adhering to its surface, achieving a self-cleaning effect for the medium.

[0031] When conveying pipe 106 moves in direction a, partition 103 closes, forming a partially enclosed environment within sand chamber 105. During this process, the sand is disturbed and tumbled due to its own weight and inertia. The opening at the bottom of conveying pipe 106 now comes into close contact with the disturbed sand area, allowing the sand to more easily enter conveying pipe 106 and be transported by spiral dragon 107 to the top of outer frame 101. This design, by leveraging the movement direction of conveying pipe 106 and the gravity of the sand, effectively optimizes sand extraction efficiency and supply stability, ensuring a continuous and efficient cleaning process.

[0032] Throughout the cleaning process, the opening and closing of the sand washing components and the reciprocating motion of the conveying pipe 106 are precisely linked, ensuring efficient sand return and dynamic sand renewal and cleaning. In particular, the optimization of the material removal direction a improves the overall operating efficiency of the equipment.

[0033] After cleaning is completed, the outer frame 101 again ascends along the track groove 204 to the top positioning position, at which time the inner frame 102 is at a convenient height for operation. The operator can separate the inner frame 102 from the outer frame 101 and take out the inner frame 102 alone, thereby conveniently taking out the cleaned metal workpiece.

[0034] In this embodiment, the conveying component includes a conveying shaft 200 that is rotatably connected to the conveying pipe 106. A spiral dragon 107 is fixed to the conveying shaft 200, which is used to push sand and gravel along the conveying pipe 106 from the bottom of the sand cavity 105 to the top of the outer frame 101. Among the multiple conveying pipes 106, a motor 201 is connected to the top of one of the conveying pipes 106. The drive shaft of the motor 201 is connected to the corresponding conveying shaft 200 to provide driving force. A protective sleeve 202 is fixed to the bottom of the multiple conveying pipes 106. Every two conveying shafts 200 are connected by a chain mechanism 203, which is housed in the protective sleeve 202 and is used to transmit power.

[0035] With this setup, the motor 201 starts and drives the connected conveyor shaft 200 to rotate. The spiral dragon 107 affixed to the conveyor shaft 200 begins to rotate, transporting sand from the bottom of the sand cavity 105 upward along the conveyor pipe 106 to the top of the outer frame 101. The sand then falls into the inner frame 102 and comes into contact with the metal workpiece. The conveyor shafts 200 of multiple conveyor pipes 106 are connected by a chain mechanism 203. The power from the motor 201 is evenly distributed to each conveyor shaft 200 within the protective sleeve 202 via the chain, enabling the spiral dragons 107 within multiple conveyor pipes 106 to operate synchronously, ensuring stable and consistent sand transportation.

[0036] In addition, the bottom protective cover 202 covers and protects the chain mechanism 203, preventing impurities such as gravel and debris from entering the chain engagement area, effectively reducing the risk of wear and jamming, and improving the stability and service life of the conveying system.

[0037] In this embodiment, the side wall of the processing box 100 is provided with a track groove 204 for limiting the moving path of the outer frame 101. The outer frame 101 is slidably connected to the track groove 204 and can move up and down in the vertical direction. A spring a205 is provided between the outer frame 101 and the track groove 204 for providing a buffering force and assisting in resetting the outer frame 101. A magnet 206 is installed on the outer frame 101, and the inner frame 102 is made of metal. The inner frame 102 and the outer frame 101 are connected and fixed by magnetic attraction. During operation, the inner frame 102 can be easily separated or assembled from the outer frame 101, which is convenient for placing and removing the workpiece.

[0038] With this setup, during operation, the operator first places the metal inner frame 102 into the outer frame 101. The magnets 206 on the outer frame 101 and the inner frame 102 are then attracted to each other, quickly securing the two. This eliminates the need for additional mechanical fasteners such as screws and clips, effectively simplifying assembly operations and improving the convenience and efficiency of loading and unloading materials.

[0039] In this embodiment, the oscillating component comprises a bracket a207 connected to the delivery tubes 106, which is used to secure the multiple delivery tubes 106 together. A diagonal track 208 is provided on the bracket a207. A guide rod 209 is connected to the bottom of the outer frame 101, which slides in engagement with the diagonal track 208. When the bracket a207 drives the delivery tubes 106 to reciprocate horizontally, the interaction between the guide rod 209 and the diagonal track 208 causes the outer frame 101 to move vertically in sync.

[0040] With the above arrangement, during operation, the bracket a207 and the multiple conveying tubes 106 mounted thereon reciprocate horizontally. Because the bracket a207 is provided with an inclined track 208, and the guide rod 209 at the bottom of the outer frame 101 slidably engages with the inclined track 208, when the bracket a207 reciprocates horizontally, the guide rod 209 slides up and down along the inclined track 208, thereby driving the outer frame 101 to reciprocate vertically.

[0041] On the one hand, the horizontal movement of the delivery tube 106 changes the position where the sand is delivered, enhancing the lateral coverage of the sand on the workpiece surface, ensuring more uniform friction between the sand and the workpiece surface and more comprehensive cleaning. On the other hand, the vertical movement of the outer frame 101 continuously changes the vertical position of the workpiece, effectively avoiding blind spots during cleaning. The combination of these two ensures that the sand rolls fully and is evenly distributed during the cleaning process, significantly improving the decontamination efficiency of the workpiece surface.

[0042] In this embodiment, the oscillating component includes not only a bracket a207 connected to the delivery tube 106, which is configured to form a sliding fit with the guide rod 209 at the bottom of the outer frame 101 and the inclined track 208, but also a bracket b210 connected to the delivery tube 106 and a cylinder 211 mounted on the processing box 100. The telescopic shaft of the cylinder 211 penetrates the processing box 100 and is fixedly connected to the bracket b210. Through the reciprocating telescopic drive of the cylinder 211, the bracket b210 can drive the delivery tube 106 to reciprocate horizontally as a whole, thereby achieving vertical movement of the outer frame 101 in conjunction with the inclined track 208.

[0043] With this arrangement, during operation, the cylinder 211 is activated, its telescopic shaft extends and retracts, pulling and pushing the bracket b210 affixed thereto, causing bracket b210 and the conveying tube 106 to reciprocate horizontally. At this point, bracket a207, through its sliding engagement with the guide rods 209 and inclined rails 208 at the bottom of the outer frame 101, converts the horizontal motion of the conveying tube 106 into vertical reciprocating motion of the outer frame 101.

[0044] In this embodiment, the partition 103 includes a fixed plate 306 fixedly mounted within the processing chamber 100. Connecting ports 307 are defined on either side of the fixed plate 306 for engagement with the delivery tube 106. Sliding plates 310 are secured to the delivery tube 106 and inserted into the connecting ports 307 on either side of the fixed plate 306, enabling relative sliding movement. The fixed plate 306 also includes multiple communication ports 308, each of which is rotatably connected to a baffle 309 that regulates the opening or closing of the communication port 308 based on the movement of the delivery tube 106 and the sliding plates 310.

[0045] With the above arrangement, during operation, the fixed plate 306 serves as the primary support structure for the partition 103 and is securely mounted within the processing chamber 100. The connecting ports 307 on either side of the fixed plate 306 cooperate with the sliding plates 310 on the delivery tube 106. As the delivery tube 106 reciprocates horizontally, the sliding plates 310 slide synchronously within the connecting ports 307. A rotatable baffle 309 is located within the communication port 308 on the fixed plate 306, which opens and closes in response to the movement of the delivery tube 106 and the sliding plates 310.

[0046] Specifically, when the delivery tube 106 moves in direction b, the sliding plate 310 drives the baffle 309 to open the communication port 308, allowing the sand and gravel to fall smoothly back into the sand cavity 105. There, the sand and gravel are disturbed, causing collisions and tumbling between the sand and gravel, thereby stripping away oil and fine debris adhering to their surfaces and achieving a self-cleaning effect for the medium. When the delivery tube 106 moves in direction a, the sliding plate 310 pushes the baffle 309 to close the communication port 308, creating a partially enclosed environment. Simultaneously, the opening at the bottom of the delivery tube 106 is brought into close proximity with the disturbed sand and gravel area, making it easier for the sand and gravel to enter the delivery tube 106 and be transported by the spiral dragon 107 to the top of the outer frame 101.

[0047] In this embodiment, the bottom of the sliding plate 310 is connected to a filter frame 300, which is configured to move with the sliding plate 310 when the delivery pipe 106 moves. A filter screen 305 is provided on the filter frame 300 to intercept sand and gravel, preventing it from flowing into the outlet pipe 109 along with the cleaning wastewater. The position of the outlet pipe 109 corresponds to the filter frame 300, ensuring that the cleaning liquid is processed by the filter screen 305 of the filter frame 300 before being discharged, achieving solid-liquid separation.

[0048] With this arrangement, during operation, the sliding plate 310 is connected to the delivery pipe 106 and slides back and forth horizontally within the connection port 307 of the partition 103 along with the delivery pipe 106. The filter frame 300 at the bottom of the sliding plate 310 moves synchronously with the flow. As the cleaning liquid flows through the cleaning chamber 104 and the sand chamber 105 and ultimately converges into the liquid outlet pipe 109 for discharge, all of the liquid must first pass through the filter screen 305. The filter screen 305 effectively intercepts sand and gravel particles entrained in the liquid flow, allowing only the cleaned liquid to enter the liquid outlet pipe 109 for discharge.

[0049] On the one hand, the linkage movement of the sliding plate 310 and the filter frame 300 can avoid local accumulation or blockage of the filter 305 due to long-term fixed use, realize dynamic filtration and automatic disturbance, reduce the risk of blockage of the filter 305, and extend the service life of the filter 305; on the other hand, by setting a physical filtration barrier in front of the liquid outlet pipe 109, the loss of particles in the discharge process is greatly reduced, which not only protects the downstream pipelines and equipment from blockage, but also provides conditions for the recovery of sand and gravel, thereby improving the resource utilization of the system.

[0050] In this embodiment, the sand washing unit includes a connecting shaft 301 rotatably connected to a connection port 307. A baffle 309 is fixed to the connecting shaft 301 to control the opening and closing of the communication port 308 on the fixed plate 306. Guide cylinders a302 are connected at each end of the connecting shaft 301, each having a spiral opening a303 formed therein. A push rod a304 is provided on the sidewall of the sliding plate 310, which slidably engages with the spiral opening a303 on the guide cylinder a302.

[0051] With this arrangement, during operation, the sliding plate 310 and the delivery tube 106 reciprocate horizontally in sync. A push rod a304 on the sidewall of the sliding plate 310 tightly engages the spiral opening a303 on the guide cylinder a302. As the sliding plate 310 slides back and forth, the push rod a304 rotates the guide cylinder a302 along the helical path of the spiral opening a303. The rotation of the guide cylinder a302 is transmitted through the connecting shaft 301, driving the baffle 309 on the connecting shaft 301 to rotate, thereby opening or closing the communication port 308 of the fixed plate 306.

[0052] In this embodiment, the sand washing component also includes a plurality of disturbance shafts 400 rotatably connected to the bottom of the fixed plate 306. Each disturbance shaft 400 is connected to a plurality of stirring blades 401 for disturbing the sand in the sand cavity 105. The two ends of the disturbance shaft 400 are respectively connected to a guide cylinder b402, and a spiral opening b403 is provided on the guide cylinder b402. A push rod b404 is fixed to the bottom of the sliding plate 310, and the push rod b404 slides in conjunction with the spiral opening b403 on the guide cylinder b402. When the sliding plate 310 moves horizontally with the conveying pipe 106, the push rod b404 slides in the spiral opening b403, driving the guide cylinder b402 to rotate, thereby driving the disturbance shaft 400 and its stirring blades 401 to rotate, thereby disturbing the sand in the sand cavity 105.

[0053] With this arrangement, during the cleaning process, the sliding plate 310 and the delivery tube 106 move back and forth horizontally in sync. A push rod b404 at the bottom of the sliding plate 310 fits tightly within a spiral opening b403 on the guide cylinder b402. As the sliding plate 310 moves horizontally, the push rod b404 slides within the spiral opening b403, causing the guide cylinder b402 to rotate. This rotational motion of the guide cylinder b402, connected through its two ends, drives the agitation shaft 400, causing the stirring blades 401 on the agitation shaft 400 to rotate.

[0054] In this embodiment, the push rod a304 is slidably disposed on the sliding plate 310 and is connected to the sliding plate 310 via a spring b405. The spiral opening a303 on the guide cylinder a302 is shorter than the spiral opening b403 on the guide cylinder b402.

[0055] With this arrangement, during the cleaning process, when the delivery pipe 106 drives the sliding plate 310 in horizontal reciprocating motion, the push rod a304 on the sliding plate 310 slides within the spiral opening a303, causing the guide cylinder a302 to rotate rapidly, thereby allowing the baffle 309 to more quickly open or close the communication port 308. Due to the short length and steep pitch of the spiral opening a303, the push rod a304 can achieve a large rotation angle with a small sliding displacement, allowing the baffle 309 to respond quickly and precisely control the flow or blockage of the gravel. The rapid opening and closing of the baffle 309 allows for more precise switching of the gravel flow state, avoiding feed interruptions caused by delays.

[0056] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
