[0001] The utility model relates to a raw material cleaning treatment equipment technical field, especially a kind of raw material pretreatment machine with ultrasonic cleaning function. BACKGROUND

[0002] Raw material pretreatment machine is a kind of equipment for processing various raw materials, commonly used for pretreating metal raw materials for subsequent processing. Its purpose is to clean, heat or surface treat metal raw materials by mechanical force, heat or chemical reaction, thereby improving the performance and adaptability of the raw materials. Among them, under laboratory conditions, metal raw material pretreatment machine needs to clean and surface treat a variety of different types and shapes of metal raw materials to test the performance of various metal raw materials after treatment. For the fixation of different types and shapes (cylindrical, triangular, planar, parallelogram, special-shaped, etc.) of metal raw materials, the existing raw material pretreatment machine needs to use different special fixtures to fix the metal raw materials to be treated during pretreatment to prevent deviation during processing. However, for the fixation of different types and shapes of metal raw materials, different special fixtures need to be frequently replaced. And during the cleaning process of metal raw materials using special fixtures, sometimes the cleaning pose needs to be changed and the clamping position needs to be changed to achieve the purpose of thorough cleaning.

[0014] An L-shaped frame is hinged in the hinged seat, and a hinge shaft at the hinged position is arranged in the longitudinal direction; one end of the L-shaped frame towards the drainage pipe is provided with a plugging head.

[0015] A driving mechanism is installed on the base and is configured to drive the L-shaped frame to rotate so as to plug or open the drainage pipe.

[0016] Optionally, the driving mechanism comprises a connecting rod, a connecting frame and an electric push rod.

[0018] The connecting frame has one first rod body and two second rod bodies; the two second rod bodies are arranged in parallel; the first rod body is connected to two ends on the same side of the two second rod bodies; and one end of the connecting rod away from the L-shaped frame is rotatably installed between the two second rod bodies through a hinge shaft.

[0019] The electric actuator is mounted on the upper end of the base. The push shaft at the output end of the electric actuator extends in the lateral direction and is rotatably connected to the first rod body at the end via a hinge shaft. The electric actuator is configured to drive the push shaft at the end to reciprocate in the lateral direction.

[0020] Optionally, a limiting platform is installed on the upper end of the base, and the limiting platform has a limiting hole that extends through in the lateral direction. The push shaft at the output end of the electric push rod is laterally slidably engaged in the limiting hole.

The radial engagement of the slide table at the lower end of the connecting rod with the slide groove restricts the connecting rod to move only radially towards the center or away from the center, enabling the clamping plates at the upper ends of the multiple connecting rods to clamp metal raw materials of different shapes. The clamping of multiple connecting rods replaces traditional dedicated clamps, making it a universal clamp suitable for clamping and positioning various types and shapes of metal raw materials, thus improving the adaptability of the clamping. The clamping is reliable, and the cleaning posture of the raw materials can be flexibly adjusted as needed, improving the uniformity and effectiveness of the cleaning.

This ensures the fluidity of the liquid and the continuity of the cleaning effect during the cleaning process, avoids corrosion or blockage caused by excessive liquid, ensures the long-term stable operation of the equipment, extends the service life of the equipment, avoids unnecessary maintenance and downtime, and further improves production efficiency.

[0031] Furthermore, in the raw material pretreatment machine with ultrasonic cleaning function of this utility model, the L-shaped frame is rotated to change the position of the sealing head in the outlet sealing structure, thereby achieving the sealing effect of the sealing head, realizing automated sealing, and improving the automation level of the device.

[0032] Furthermore, in the raw material pretreatment machine with ultrasonic cleaning function of this utility model, the outlet sealing structure converts the lateral reciprocating motion of the electric push rod into the rotation of the L-shaped frame through a linkage mechanism, thereby reducing the space required for the layout. The lateral movement of the electric push rod is smooth and the movement stroke is easier to control.

[0043] Unless otherwise expressly specified and limited, the terms "set," "install," "connect," "link," "fix," and "couple" should be interpreted broadly.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0046] like Figure 1 As shown, and refer to Figures 2 to 7 This utility model provides a raw material pretreatment machine with ultrasonic cleaning function, including a pretreatment chamber 1, an ultrasonic cleaning system, and at least one clamping mechanism 2.

[0047] The pretreatment chamber 1 has an opening at the top for adding metal raw materials and cleaning fluid. An ultrasonic cleaning system is installed on the side wall of pretreatment chamber 1. This system is configured to use ultrasound to clean the metal raw materials in the cleaning fluid. Specifically, ultrasonic cleaning utilizes the cavitation, acceleration, and direct flow effects of high-frequency sound waves in a liquid to directly and indirectly act on the liquid and contaminants, dispersing, emulsifying, and peeling off the contaminant layer to achieve the cleaning purpose, thereby efficiently removing stains, grease, particles, and other contaminants from the surface of objects. Its working principle is that when ultrasound propagates in a liquid, it generates acoustic cavitation due to nonlinear effects. The shock wave emitted when the cavitation bubbles suddenly collapse can generate thousands of atmospheres of pressure around them, directly and repeatedly impacting the contaminant layer. This disrupts the adhesion between the contaminants and the surface of the cleaned object, and also causes the contaminant layer to detach from the surface and disperse into the cleaning fluid. The vibration of the bubbles can also scrub solid surfaces. The bubbles can even "drill" into cracks and vibrate, causing contaminants to fall off. For oily contaminants, ultrasonic cavitation causes the two liquids to rapidly disperse and emulsify at the interface. When solid particles are coated with oil and adhere to the surface of the part being cleaned, the oil is emulsified, and the solid particles detach. During vibration, the cavitation bubbles create circulation within the liquid itself, a phenomenon known as acoustic flow. This creates a high velocity gradient and viscous stress on the surface of the vibrating bubbles, promoting the breakdown and removal of contaminants from the surface of the part being cleaned. The high-speed microjets generated by ultrasonic cavitation on the solid and liquid surfaces can remove or weaken boundary contaminant layers, corrode solid surfaces, increase agitation, accelerate the dissolution of soluble contaminants, and enhance the cleaning effect of chemical cleaning agents. Furthermore, ultrasonic cleaning systems require a cleaning medium, typically a chemical solvent or a water-based cleaning agent.

[0048] Specifically, the ultrasonic cleaning system includes an ultrasonic generator 13 and an ultrasonic transducer 14. The ultrasonic generator 13 converts electrical energy into a high-frequency alternating current signal that matches the ultrasonic transducer 14. The ultrasonic transducer 14 converts the input electrical power into mechanical power, i.e., ultrasonic waves, and transmits them, while consuming very little power itself. As the core component of the ultrasonic cleaning system, the ultrasonic transducer 14 is typically made of piezoelectric ceramic materials, such as lead zirconate titanate (PZT). The ultrasonic transducer 14 utilizes ultrasonic waves to generate vibrations, which, by being evenly distributed within the chamber, help ensure that all parts of the surface of the raw material to be treated are thoroughly cleaned.

[0049] At least one clamping mechanism 2 is located at the bottom of the pretreatment chamber 1. This universal clamping structure allows for the clamping of raw materials of different types and shapes. The clamping structure's location at the bottom of the pretreatment chamber 1 ensures that the metal raw material to be cleaned is fully immersed in the cleaning solution. Each clamping mechanism 2 includes a fixed base 3, a rotating wheel 5, multiple clamping components 7, and a driving component 8.

[0050] The fixing base 3 is installed on the bottom surface of the pretreatment chamber 1, and multiple sliding grooves 4 are provided on the upper end of the fixing base 3. Specifically, the fixing base 121 can be fixedly installed on the bottom of the pretreatment chamber 1 by bolts or welding. The rotating wheel 5 is rotatably set above the fixing base 3. The rotating wheel 5 is provided with multiple arc-shaped holes 6, which extend along the direction of the vortex line, and the vortex line gradually extends outward from the starting point to the ending point. Specifically, the arc-shaped holes 6 are vertically penetrating, and the extension direction of the arc-shaped holes 6 is arc-shaped, but not a regular circular arc structure, but extends along the vortex line. The vortex line is a curve that rotates outward around a center point in a plane and gradually moves away from or closer to it. Here, a vortex line that gradually moves away from the center is used. The characteristic of the vortex line is that for every rotation of the endpoint of the vortex line, the polar angle (radian) increases by 360°, and the distance between the endpoint and the center increases by a fixed length, i.e., the pitch. If the increase in pitch is constant, it can be regarded as an equidistant spiral. The rotation of the wheel 5 can be achieved by connecting it to the fixed base 3 via a connecting bearing.

[0051] Each clamping component 7 corresponds one-to-one with the slide groove 4 and the arc-shaped hole 6. That is to say, the number and position of each clamping component 7 correspond to the number of slide grooves 4 and arc-shaped holes 6, which facilitates clamping. Each clamping component 7 includes a clamping plate 701, a connecting rod 702, and a slide table 703.

[0052] The connecting rod 702 extends vertically and is disposed within the corresponding arc-shaped hole 6, slidingly engaging with the arc-shaped hole 6 along its extension direction. Specifically, the connecting rod engages vertically within the arc-shaped hole 6 and slides along its extension direction, changing its distance from the rotation center. Moving outwards towards the arc-shaped hole 6 increases the distance from the rotation center, while moving inwards decreases the distance. The outer circumferential wall of the connecting rod 702 is fitted against the inner arc of the arc-shaped hole 6 for limiting sliding, restricting the connecting rod 702 to move only along the extension direction of the arc-shaped hole 6, thus increasing or decreasing the distance between the connecting rod 702 and the center of the rotating wheel 5. The arc-shaped hole 6 serves to guide the direction of movement of the connecting rod 702.

[0053] The lower end of the connecting rod 702 is connected to the slide table 703, which slides along the radial direction of the rotating wheel 5 within the corresponding groove 4. In other words, the slide table 703 is installed at the lower end of the connecting rod 702, and the fit between the slide table 703 and the groove 4 allows the slide table 703 to move only along the direction of the groove 4, which is set along the radial direction of the rotating wheel 5. The groove 4 and the slide table 703 are designed to restrict the rotation of the connecting rod 702 during its movement within the arc-shaped hole 6, and to limit its vertical displacement, ensuring it can only move along the extension direction of the arc-shaped hole 6. Due to the restriction of the slide table 703 and the groove 4, the connecting rod 702 can only move radially along the rotating wheel 5 relative to the fixed base 3. This allows for adjustment of the connecting rod 702's radial position. The upper end of the connecting rod 702 is connected to a clamping plate 701 positioned above the rotating wheel 5. Specifically, the clamping plate 701 is positioned above the rotating wheel 5. Since the connecting rod 702 cannot rotate, the clamping plate 701 also cannot rotate, allowing it to move only in the radial direction of the rotating wheel 5. Thus, the rotation of the rotating wheel 5 can be converted into linear movement of the connecting rod 702 and the clamping plate 701 along the radial direction of the rotating wheel 5, achieving the purpose of clamping.

[0054] The drive component 8 is installed within the fixed base 3. The drive component 8 is configured to drive the rotating wheel 5 to reciprocate around its center on a horizontal plane at a preset angle. In other words, the output end of the drive component 8 is connected to the rotating wheel 5, providing power input. The preset angle is the arc angle of the arc-shaped hole 6. The angle at which the drive component 8 drives the rotating wheel 5 to reciprocate cannot exceed the arc angle of the arc-shaped hole 6, i.e., the polar angle. It is important to note that since the pretreatment chamber 1 is filled with cleaning fluid, the drive component 8 must be sealed and protected to prevent contamination by the cleaning fluid. This can be achieved by creating a sealed space inside the fixed base 3, installing the drive component 8 within this space, with its output shaft extending out of the fixed base 3 and installed with the rotating wheel 5. A mechanical seal is installed between the output shaft and the fixed base 3 to protect the drive component 8.

[0055] In this embodiment, the raw material pretreatment machine with ultrasonic cleaning function operates by first placing the raw material parts to be cleaned in the desired position between multiple clamping plates 701. By activating the drive unit 8, the drive unit 8 drives the rotating wheel 5 to rotate. The rotation of the rotating wheel 5 causes the connecting rod 702 to move along the arc-shaped hole 6 within the arc-shaped hole 6. Due to the radial sliding limitation between the slide table 703 and the slide groove 4, the connecting rod 702 can only move inward relative to the fixed seat 3 along the radial direction of the rotating wheel 5. During the inward movement of the multiple clamping plates 701, the raw material to be cleaned is clamped. When a change in cleaning position is required, the drive unit 8 is activated to drive the rotating wheel 5 to rotate in the opposite direction, opening the multiple clamping plates 701 outward. After changing the cleaning position, the drive unit 8 is activated again, and the multiple clamping plates 701 move towards the center of the rotating wheel 5 to clamp the raw material to be cleaned. Then, cleaning agent is introduced into the pretreatment chamber 1. The ultrasonic cleaning system is then activated to clean the raw material.

[0056] In this embodiment of the invention, the reciprocating rotation of the rotating wheel 5 drives multiple connecting rods 702 to move synchronously within the corresponding arc-shaped holes 6 of the rotating wheel 5. The slide table 703 at the lower end of the connecting rod 702 radially engages with the slide groove 4, restricting the connecting rod 702 to move only radially towards the center or away from the center along the radial direction of the rotating wheel 5. This enables the clamping plate 701 at the upper end of the multiple connecting rods 702 to clamp metal raw materials of different shapes. The clamping of multiple connecting rods 702 replaces traditional dedicated clamps, making it a universal clamp suitable for clamping and positioning various types and shapes of metal raw materials, thus improving the adaptability of the clamping. The clamping is reliable, and the cleaning posture of the raw materials can be flexibly adjusted as needed, improving the uniformity and cleaning effect of the cleaning.

[0057] In some embodiments of this utility model, such as Figure 5 As shown, multiple sliding grooves 4 are evenly spaced along the circumference of the rotating wheel 5 on the fixed base 3. Multiple arc-shaped holes 6 are also evenly spaced along the circumference of the rotating wheel 5. Specifically, the multiple sliding grooves 4 and arc-shaped holes 6 are evenly distributed along the circumference of the rotating wheel 5. Since the clamping members 7 that cooperate with them are one-to-one, the clamping plates 701 in the clamping members 7 are also one-to-one, facilitating synchronous movement, and the distance from the clamping plate 701 to the center changes synchronously. In this embodiment, the advantage of even distribution is that during clamping, the force is uniform, avoiding local stress concentration and improving the static stability during clamping.

[0058] In some embodiments of this utility model, such as Figure 6As shown, the slide grooves 4 extend radially along the rotating wheel 5, and the cross-section of the slide groove 4 is a semi-circular arc structure. That is, the bottom surface of the slide groove 4 is entirely arc-shaped, and the surface of the slide groove 4 is smooth. Baffles 9 are provided on both sides of the upper end of the slide groove 4, each baffle 9 being arranged along the extending direction of the slide groove 4 and positioned above the slide groove 4. Specifically, the baffles 9 are arranged along the extending direction of the slide groove 4, i.e., the radial direction of the rotating wheel 5, and baffles 9 are provided on both the left and right sides of the upper end of the slide groove 4, extending above the slide groove 4 and obscuring the structure of the slide groove 4 on both sides.

[0059] The slide table 703 is an arc-shaped plate structure extending radially along the roller 5, with a semi-circular cross-section. The lower arc surface of the slide table 703 slides in conjunction with the corresponding arc bottom surface within the slide groove 4. The two planes at the upper end of the slide table 703 abut against the lower end surfaces of the corresponding side baffles 9. Specifically, the slide table 703 is fitted into the slide groove 4 and slides relative to it along the extension direction of the slide groove 4, i.e., along the radial direction of the roller 5. The left and right sides of the upper end of the slide table 703 are flush plane structures, abutting against the lower end of the baffles 9 to prevent the slide table 703 from detaching upwards from the slide groove 4, thus restricting its upward movement and ensuring that the slide table 703 can only move along the extension direction of the slide groove 4, i.e., along the radial direction of the roller 5. In this embodiment, the radial fit between the arc-shaped slide groove 4 and the arc-shaped slide table 703 facilitates assembly and processing of the groove and the slide table 703, improving economic efficiency.

[0060] In some embodiments of this utility model, such as Figure 7 As shown, the line connecting the starting point of the vortex to the center of the rotor 5 is defined as line L1, and the line connecting the ending point of the vortex to the center of the rotor 5 is defined as line L2. The angle between line L1 and line L2 is α, and the value of angle α is 60°-90°. That is to say, the polar angle between the starting and ending points of the vortex can be 60°-90°. The angle α should not be too large, so that its distance on the rotor 5 is also not too large, thus achieving a small angle and a large stroke. The advantage of this setting is that the small angle and large stroke setting of the arc-shaped hole 6 can provide structural strength to the rotor 5, avoiding the reduction in structural strength caused by the porous structure.

[0061] In some embodiments of this utility model, such as Figures 1-4As shown, a liquid outlet 10 is provided on the right side wall of the pretreatment chamber 1, and a drain pipe 11 is connected to the liquid outlet 10. An outlet sealing structure 12 is provided at the outlet of the drain pipe 11, which is used to seal or open the drain pipe 11. Specifically, the liquid outlet 10 is set at a low position to facilitate the smooth discharge of the cleaning liquid in the pretreatment chamber 1. The outlet sealing structure 12 is opened to discharge the cleaning liquid after cleaning is completed, or to replace the cleaning liquid in the pretreatment chamber 1 in real time, so as to ensure the internal cleaning liquid renewal speed. In this embodiment, by setting the liquid outlet 10, the drain pipe 11, and the outlet sealing structure 12, it is ensured that the cleaning liquid is discharged in a timely manner and that no liquid accumulation or retention occurs during the cleaning process. This ensures the fluidity of the liquid and the continuity of the cleaning effect during the cleaning process, avoids corrosion or blockage caused by excessive liquid, ensures the long-term stable operation of the equipment, extends the service life of the equipment, avoids unnecessary maintenance and downtime, and further improves production efficiency.

[0062] In some embodiments of this utility model, such as Figures 1-4 As shown, the outlet sealing structure 12 includes: a base 121, a hinged seat 122, an L-shaped frame 123, and a drive mechanism 125.

[0063] The base 121 is installed at the lower end of the pretreatment chamber 1. Specifically, the base 121 can be installed at the lower end of the pretreatment chamber 1 by welding or threaded connection. The hinge seat 122 is installed at the right end of the base 121. The L-shaped frame 123 is hinged within the hinge seat 122, and the hinge shaft at the hinge point extends longitudinally. A sealing head 124 is provided at the end of the L-shaped frame 123 facing the drain pipe 11. Specifically, the hinge seat 122 is provided with a hinge hole, and the L-shaped frame 123 is provided with a longitudinally extending hinge shaft. The hinge shaft is inserted into the hinge holes on the front and rear sides of the hinge seat 122 to achieve a hinged structure, allowing the L-shaped frame 123 to rotate in a vertical plane. The sealing head 124 can be made of rubber. During the rotation of the L-shaped frame 123, the sealing head 124 can be rotated to the outlet of the drain pipe 11 to achieve sealing.

[0064] A drive mechanism 125 is mounted on a base 121 and configured to drive the L-shaped frame 123 to rotate, thereby causing the sealing head 124 to either seal or open the drain pipe 11. Specifically, the drive mechanism 125 drives the L-shaped frame 123 to rotate. The change in rotation position changes the position of the sealing head 124, thus allowing the sealing head 124 to open or seal the drain pipe 11. In this embodiment, the rotation of the L-shaped frame 123 changes the position of the sealing head 124, achieving the sealing effect of the sealing head 124, realizing automated sealing, and improving the automation level of the device.

[0065] In some embodiments of this utility model, such asFigure 3 As shown, the drive mechanism 125 includes a connecting rod 1251, a connecting frame 1252, and an electric push rod 1253. In this embodiment, the connecting rod 1251 mechanism is used to convert linear drive into rotational motion output by the drive mechanism 125.

[0066] The connecting rod 1251 is installed at the end of the L-shaped frame 123 away from the sealing head 124. The connecting frame 1252 has a first rod 1254 and two second rods 1255, which are arranged in parallel. The first rod 1254 is connected to the two ends of the two second rods 1255 on the same side. The end of the connecting rod 1251 away from the L-shaped frame 123 is rotatably installed between the two second rods 1255 via a hinge shaft. Specifically, the first rod 1254 and the second rod 1255 form a U-shaped connecting frame 1252 structure. Hinge holes are respectively opened on the second rods 1255, and a hinge shaft is arranged longitudinally on the connecting rod 1251. The hinge shaft is inserted into the hinge holes on the two second rods 1255 to achieve hinge connection.

[0067] An electric actuator 1253 is mounted on the upper end of the base 121. The push shaft 1256 at the output end of the electric actuator 1253 extends laterally and is rotatably connected to the first rod body 1254 at its end via a hinge shaft. The electric actuator 1253 is configured to drive the push shaft 1256 at its end to reciprocate laterally. Specifically, the hinge between the push shaft 1256 at the output end of the electric actuator 1253 and the left end of the first rod body 1254 is achieved by providing a hinge hole at the right end of the push shaft 1256 and a hinge hole at the left end of the first rod body 1254. A hinge shaft is inserted into both hinge holes to achieve the hinge between the first rod body 1254 and the push shaft 1256, wherein the hinge shaft is positioned longitudinally. The electric actuator 1253 outputs a lateral reciprocating pushing force.

[0068] In this embodiment, the raw material pretreatment machine with ultrasonic cleaning function operates by activating the electric push rod 1253. The push shaft 1256 at the output end of the electric push rod 1253 moves to the right, causing the connecting frame 1252 to move to the right. This drives the connecting rod 1251, connected to the L-shaped frame 123, to rotate upwards around the hinge axis. At this time, the right end of the connecting frame 1252 lifts upwards, and the L-shaped frame 123 rotates downwards, opening the outlet of the drain pipe 11 with the sealing head 124. Conversely, the sealing head 124 blocks the outlet of the drain pipe 11. In this embodiment, the lateral reciprocating motion of the electric push rod 1253 is converted into the rotation of the L-shaped frame 123 through the connecting rod 1251 mechanism, reducing the space required for the layout. The lateral movement of the electric push rod 1253 is smooth and the travel distance is easier to control.

[0069] In some embodiments of this utility model, such as Figure 3As shown, the raw material pretreatment machine with ultrasonic cleaning function also includes: a limiting platform 1257, which is installed on the upper end of the base 121. The limiting platform 1257 has a limiting hole that extends through in the lateral direction. The push shaft 1256 at the output end of the electric push rod 1253 is laterally slidably fitted into the limiting hole. Specifically, the limiting platform 1257 is used to restrict the lateral movement of the push shaft 1256 at the output end of the electric push rod 1253, so that it can move laterally smoothly and avoid lateral displacement of the push shaft 1256 due to external force.

[0070] In some embodiments of this utility model, such as Figure 4 As shown, the ultrasonic cleaning system includes an ultrasonic generator 13 and multiple ultrasonic transducers 14. The ultrasonic generator 13 is mounted on the side wall of the pretreatment chamber 1, and the multiple ultrasonic transducers 14 are disposed inside the pretreatment chamber 1. The ultrasonic generator 13 and the multiple ultrasonic transducers 14 cooperate to clean the raw materials in the pretreatment chamber 1. Specifically, the multiple ultrasonic transducers 14 enable cleaning of the raw materials from multiple directions within the pretreatment chamber 1, thereby improving the efficiency of the entire pretreatment process, ensuring that each piece of raw material achieves a consistent treatment effect, and providing higher quality raw materials for subsequent processing steps.

[0071] In some embodiments of this utility model, such as Figure 1 As shown, the driving component 8 is a programmable servo motor. The output shaft of the programmable servo motor extends from the fixed base 3 and is connected to the center of the rotating wheel 5. Specifically, the output shaft of the programmable servo motor extends from the fixed base 3 and is fixedly connected to the center of the rotating wheel 5. The rotation of the programmable servo motor can drive the rotating wheel 5 to rotate. The programmable servo motor can be a Beckhoff AM8000 intelligent industrial production servo motor. By setting the corresponding code in its internal encoder, feedback is sent to the controller, thereby controlling the rotation direction and angle of the servo motor output shaft, ensuring that the output shaft of the driving component 8 achieves a predetermined angle of forward and reverse rotation. It is important to note that during the rotation of the rotating wheel 5, the material is clamped. The rotation of the servo motor output shaft must be programmed to respond; that is, after rotating to the clamping point, the servo motor must stop rotating after receiving the clamping completion signal. In this example, the programmable servo motor is used to automate the driving part of the clamping mechanism 2, realizing automated production and improving production efficiency.

[0072] In some embodiments of this utility model, such as Figure 5 As shown, the clamping plate 701 is configured as an arc-shaped plate structure, which facilitates the clamping of the metal raw materials therein.

[0073] In some embodiments of this utility model, such as Figure 2As shown, a support 15 is provided at the bottom of the pretreatment chamber 1. The support 15 structure serves to support the entire device. Furthermore, a travel wheel with a locking structure can be provided at the lower end of the chamber, which facilitates movement and can also be used to fix the entire device in a fixed position by locking the travel wheel.

[0074] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
