[0048] See also Figure 1 , Figure 1 The schematic diagram of the structure of a cleaning device in one embodiment of the present invention is shown. The cleaning device 100 provided in one embodiment of the present invention includes a device body 200 and a cleaning fixture 300. The cleaning fixture 300 is arranged on the device body 200, and the cleaning fixture 300 is used to clamp and position a tool 302. The device body 200 includes a cleaning device, and the cleaning device is used to output a cleaning medium to clean the blind hole of the tool 302 on the cleaning fixture 300, and the blind hole includes but is not limited to the internal cooling hole (cooling hole) of the tool 302.

[0049] See also Figures 2 to 7 , Figure 2 FIG. 1 shows a schematic diagram of the structure of a cleaning fixture of the cleaning device in this embodiment. Figure 3 Shows Figure 2 A schematic diagram of the cleaning fixture from another perspective. Figure 4 Shows Figure 2 Exploded view of the cleaning fixture. Figure 5 Shows Figure 2 A top view of the cleaning fixture. Figure 6 Shows Figure 5 A cross-sectional view of the cleaning fixture along II, Figure 7 Shows Figure 5The cleaning fixture 300 is a cross-sectional view along II-II, and the cleaning fixture 300 includes a fixture body 310 and a clamping structure 320. The fixture body 310 is provided with a clamping portion 311 and a cleaning channel 312. The clamping structure 320 is provided on the fixture body 310, and the clamping structure 320 cooperates with the clamping portion 311 to clamp or release the tool 302. Among them, one end of the cleaning channel 312 is provided corresponding to the clamping portion 311, and is used to connect the blind hole of the tool 302, and the other end of the cleaning channel 312 is connected to the cleaning device, and is used to input the cleaning medium to clean the blind hole. By setting the clamping structure 320 to cooperate with the clamping portion 311, the tool 302 is clamped and positioned; and by setting the cleaning channel 312, the blind hole of the tool 302 and the cleaning device are connected, and the cleaning medium output by the cleaning device enters the inner cooling hole of the tool 302 through the cleaning channel 312 to clean the inner cooling hole. Therefore, the cleaning fixture 300 can realize the cleaning of the inner cooling hole of the tool 302 in a non-open environment without manually holding the tool 302, and the cleaning medium can be high-pressure liquid and / or high-pressure gas, thereby improving the cleaning efficiency.

[0050] In this embodiment, the clamp body 310 is further provided with a mounting hole 313 and an inner flow channel 314. At least part of the hole wall of the mounting hole 313 forms a clamping portion 311, the mounting hole 313 is connected to the cleaning flow channel 312, and one end of the inner flow channel 314 is arranged on the inner side of the clamping portion 311. The clamping structure 320 includes an inner fluid 321 and a driving structure 322, the inner fluid 321 is sealed in the inner flow channel 314, and one end of the driving structure 322 is movably arranged at the other end of the inner flow channel 314, and is used to drive the inner fluid 321 to flow in the inner flow channel 314, so as to expand or contract the clamping portion 311. When the driving structure 322 moves inward along the inner flow channel 314, it drives the internal fluid 321 to flow inward along the inner flow channel 314 to the clamping portion 311. Under the action of the fluid pressure, the clamping portion 311 expands inward and can clamp the tool 302. When the driving structure 322 moves outward along the inner flow channel 314, the internal fluid 321 flows outward along the inner flow channel 314 and leaves the clamping portion 311. The clamping portion 311 contracts outward and can release the tool 302.

[0051] It should be noted that, in other embodiments, the clamping portion 311 can be arranged on the outer peripheral surface of one end of the clamp body 310, and one end of the inner flow channel 314 is arranged corresponding to the outer peripheral surface. One end of the clamp body 310 is inserted into the inner cooling hole of the tool 302, and its outer peripheral surface is adapted to the hole wall of the inner cooling hole. Then, the outer peripheral surface is expanded and tightened to the inner cooling hole through the clamping structure 320, wherein the mounting hole 313 can serve as part of the cleaning flow channel 312 and connect to the inner cooling hole of the tool 302. In addition, in other embodiments, the clamping structure 320 can be an elastic structure, which clamps or releases the tool 302 by telescoping, and the clamping portion 311 can be the hole wall of the mounting hole 313, the tool 302 is inserted into the mounting hole 313 and matched with its hole wall, and then is clamped and positioned under the action of the elastic structure; or, the clamping portion 311 is the outer peripheral surface of one end of the fixture body 310, and one end of the fixture body 310 is inserted into the inner cooling hole of the tool 302, and its outer peripheral surface is matched with the hole wall of the inner cooling hole, and then under the action of the elastic structure, the tool 302 is expanded and positioned.

[0052] In order to facilitate the clamping of tools 302 of different diameters, the cleaning fixture 300 also includes a jacket 330, which is detachably matched with the clamping portion 311, and is used to sleeve the tool 302. When in use, the jacket 330 is first sleeved on the clamping section of the tool 302, and then the jacket 330 is inserted into the clamping portion 311 to cooperate with the clamping portion 311; after cleaning, the jacket 330 is taken out together with the tool 302. By using jackets 330 with different apertures and installing tools 302 of different diameters, when cleaning, the jacket 330 is directly inserted into the clamping portion 311 and the tool 302 is installed, which meets the requirements of rapid cleaning of the internal cooling holes of different tools 302 and further improves the cleaning efficiency.

[0053] Furthermore, the outer circumference of the jacket 330 is tightly matched with the clamping portion 311 and sealed, and the inner circumference of the jacket 330 is tightly matched with the clamping section of the tool 302 and sealed, which is beneficial to improving the cleaning effect of the inner cooling hole of the tool 302. The jacket 330 is made of a soft elastic material for sealing, and its material can be but not limited to rubber.

[0054] In this embodiment, the clamp body 310 is further provided with an outer flow channel 315. The other end of the driving structure 322 is movably sealed and connected to one end of the outer flow channel 315, and the other end of the outer flow channel 315 is used to input or output the external fluid to move the driving structure 322. When the outer flow channel 315 inputs the external fluid, the external fluid fills the outer flow channel 315 and pushes the driving structure 322 to move, and at the same time pushes the internal fluid 321 to flow inward, at which time the internal fluid 321 expands the clamping part 311; when the outer flow channel 315 outputs the external fluid, the external fluid cancels the push on the driving structure 322, and the driving structure 322 moves outward, at which time the clamping part 311 shrinks. It should be noted that in other embodiments, the driving structure 322 can also be driven by a motor assembly, an electric-controlled telescopic rod, or a connecting rod driving mechanism, and moves in the inner flow channel 314 to increase or reduce the pressure of the internal fluid 321.

[0055] In this embodiment, the cleaning fixture 300 further includes a stopper 340, which is disposed at the other end of the inner flow channel 314. The fixture body 310 includes a first body 316 and a second body 317 connected to each other, the mounting hole 313 and the inner flow channel 314 are both disposed in the first body 316, and the outer flow channel 315 is disposed in the second body 317. The driving structure 322 includes a first driving member 323 and a second driving member 324. One end of the first driving member 323 is movably and sealedly connected to the inner flow channel 314, and the other end of the first driving member 323 passes through the stopper 340 and is connected to one end of the second driving member 324. One end of the first driving member 323 is limited in the inner flow channel 314 by the stopper 340, and will not be separated from the inner flow channel 314, so that the first driving member 323 can be fixed in the first body 316, so as to divide the cleaning fixture 300 into independent functional modules for easy assembly. The other end of the second driving member 324 is movably sealed and connected to the outer flow channel 315. It is understandable that in other embodiments, in the absence of the limit member 340, the driving structure 322 of the cleaning fixture 300 can also realize the liquid expansion or contraction of the clamping portion 311, and the driving structure 322 can only include the first driving member 323.

[0056] Further, one end of the first driving member 323 is sealed and connected to the inner flow channel 314 through a sealing ring, without affecting its movement on the inner flow channel 314. The other end of the second driving member 324 is sealed and connected to the outer flow channel 315 through a sealing ring, without affecting its movement on the outer flow channel 315. It can be understood that in other embodiments, the inner fluid 321 is sealed in the inner flow channel 314 through a deformable diaphragm, and the driving structure 322 drives the diaphragm to move to increase or reduce the pressure of the inner fluid 321.

[0057] In this embodiment, the first driving member 323 and the second driving member 324 are both pistons. In other embodiments, the first driving member 323 and the second driving member 324 can be integrally formed with a convex ring to achieve a sealed connection without adding a sealing ring.

[0058] In this embodiment, the cleaning channel 312 includes a first channel section 318 and a second channel section 319 which are connected. The first channel section 318 is tilted in the first sub-body 316, and the second channel section 319 is disposed in the second sub-body 317 and is stepped from outside to inside. Since the first channel section 318 is tilted, the cleaning medium outputted by it is directed toward the center of the clamping portion 311 to better enter the inner cooling hole, and a vortex can be formed when entering the inner cooling hole, thereby improving the cleaning effect of the inner cooling hole. Since the second channel section 319 is stepped from outside to inside, that is, the channel becomes smaller inward, and the pressure of the cleaning medium is increased, the cleaning effect of the inner cooling hole can also be improved.

[0059] In this embodiment, the inlet of the second flow channel section 319 is disposed at one end of the clamp body 310, the inlet of the outer flow channel 315 is also disposed at the same end of the clamp body 310, and the mounting hole 313 is disposed at the other end of the clamp body 310. It is understandable that the inlet of the second flow channel section 319 and the inlet of the outer flow channel 315 can be disposed at other positions of the clamp body 310, such as the side of the clamp body 310.

[0060] See also Figures 8 to 11 , Figure 8 The module block diagram of the cleaning device in this embodiment is shown. Fig. 9 The front view of the cleaning device in this embodiment is shown. Fig.10 Shows Fig. 9 A cross-sectional view of the cleaning equipment along line III-III, Fig.11 A left view of the cleaning device in this embodiment is shown, wherein the device body 200 also includes a device frame 220 and a base 222 disposed on the device frame 220, a cleaning fixture 300 is mounted on the base 222, a cleaning device 210 is mounted below the base 222, and a cleaning flow channel 312 of a fixture body 310 of the cleaning fixture 300 is connected through the base 222.

[0061] In order to ensure the safety of cleaning the tool 302 and avoid overflow of high-pressure liquid or high-pressure gas to injure the operator, the equipment frame 220 is provided with an operating room 224, and the base 222 is arranged in the operating room 224 so that the cleaning fixture 300 is located in the operating room 224. The operating room 224 is provided with a safety door 226 that can be opened and closed. When cleaning the tool 302, the operator opens the safety door 226, clamps the tool 302 on the cleaning fixture 300, and makes the cleaning fixture 300 clamp the tool 302, then closes the safety door 226, and controls the cleaning equipment 100 to clean the tool 302. The operating room 224 can prevent the cleaning liquid from spraying out and causing safety accidents, thereby improving the safety of using strong alkaline liquid as the cleaning liquid.

[0062] Furthermore, in order to avoid the situation that the safety door 226 is not closed and the cleaning is carried out, the equipment body 200 also includes a controller 230 and an in-place sensor 240. The controller 230 is electrically connected to the cleaning device 210 and the in-place sensor 240 respectively. The in-place sensor 240 is arranged on the equipment frame 220 and corresponds to the safety door 226. The in-place sensor 240 is used to detect whether the safety door 226 is in a predetermined position, and the predetermined position can ensure that the safety door 226 is in a closed position. The controller 230 controls the operation of the cleaning device 210 according to the detection result of the in-place sensor 240. If it is detected that the safety door 226 is not in the predetermined position, the operator cannot start the cleaning operation, thereby further improving safety. The in-place sensor 240 can be, but is not limited to, an infrared sensor.

[0063] In this embodiment, the number of the operating rooms 224 can be but not limited to two, and the two operating rooms 224 are arranged side by side. A cleaning fixture 300 is provided on the base 222 in each operating room 224, so that the cleaning device 100 has two stations, that is, double-station operation, one station is performing cleaning operations, and the other station can perform knife removal and new knife installation operations. The cleaning device 100 of this embodiment integrates the two stations together, that is, one station is operating and the other station is stopped, which is suitable for the back-and-forth operation of the operator and improves the work efficiency.

[0064] In this embodiment, the equipment body 200 further includes a water mist collector 250, which is disposed on the top of the equipment frame 220. One water mist collector 250 is disposed corresponding to one cleaning fixture 300 in the operating room 224, and a through hole is disposed on the top of the equipment frame 220, which connects the internal space of the operating room 224 and the water mist collector 250, so that the water mist collector 250 can collect water mist during the cleaning process.

[0065] In this embodiment, the equipment body 200 further includes a hydraulic device 260, which is disposed on the equipment frame 220, communicated with the outer flow channel 315 of the cleaning fixture 300, and electrically connected to the controller 230. The outer fluid and the inner fluid 321 may be, but are not limited to, hydraulic oil, that is, the hydraulic device 260 may control the hydraulic oil input and output of the outer flow channel 315, thereby controlling the expansion or contraction of the clamping portion 311.

[0066] In this embodiment, the equipment body 200 further includes an in-position sensor 270, which is disposed on the equipment frame 220, corresponding to the cleaning fixture 300, and electrically connected to the controller 230. The in-position sensor 270 is used to detect whether a tool 302 is installed in the clamping portion 311. The controller 230 is used to control the hydraulic press 260 to work according to the detection result of the in-position sensor 270.

[0067] Since the working principle of the cleaning fixture 300 is to increase and squeeze the clamping part 311 through hydraulic pressure, the clamping part 311 is thin-walled and made of stainless steel with a limited elastic range. If the tool 302 is not clamped and is pressed, it will expand too much, and after several times, it will cause deformation, which will affect normal use. For this reason, the in-place sensor 270 detects whether the tool 302 is installed in the clamping part 311. If not, even if the safety door 226 is closed, the hydraulic press 260 cannot be started normally, thereby avoiding damage and failure of the clamping part 311. The in-place sensor 270 can be a reflective sensor, which determines whether the tool 302 is installed by detecting whether there is an object blocking a small section above the clamping part 311. Specifically, the in-place sensor 270 can be, but is not limited to, an infrared sensor.

Fig.13 Shows Fig.12 A schematic diagram of the structure of the filter device from another perspective, Fig.14 Shows Fig.12 A cross-sectional view of the filter device. Fig.15 Shows Fig.12 Another cross-sectional view of the filter device in the figure shows that the cleaning device 100 further includes a filter device 400, which is disposed on the device body 200. The filter device 400 has a liquid inlet 402 and a liquid outlet 404, wherein the liquid inlet 402 is used to input the liquid after cleaning the tool 302. The liquid outlet 404 is connected to the cleaning device 210 and is used to output the filtrate.

[0069] Combination Fig.10 and Fig.11, further, the filtering device 400 is located below the base 222. A platform is provided inside the equipment frame 220, and the base 222 is arranged on the platform. A liquid collecting structure 280 is provided on the platform portion between the two bases 222, and the liquid collecting structure 280 is used to collect the liquid after cleaning the tool 302 and the liquid after condensation of the water mist collector 250. Specifically, the liquid generated after the cleaning device 210 cleans the tool 302 is collected by the liquid collecting structure 280, and flows into the liquid inlet 402 of the filtering device 400, and after being filtered by the filtering device 400, it is output from the liquid outlet 404 and supplied to the cleaning device 210 for use, thereby realizing the recovery and recycling of waste liquid, saving resources, and reducing the production cost of the tool 302.

[0070] In this embodiment, the liquid collecting structure 280 is funnel-shaped and is a funnel structure, which is located above the liquid inlet 402 of the filter device 400, that is, the outlet of the liquid collecting structure 280 is arranged corresponding to the liquid inlet 402 of the filter device 400 below, and the liquid is collected by the liquid collecting structure 280 and directly flows into the liquid inlet 402 of the filter device 400, and enters the filter device 400 for filtration. The filter device 400 can perform oil-water separation, natural sedimentation, coarse filtration and fine filtration, and the filtered liquid can be supplied to the cleaning device 210 for use through a high-pressure pump.

[0071] In this embodiment, the filter device 400 includes a box body 410, a first partition 420, a baffle structure 430 and a filter element 440. The first partition 420 is disposed in the box body 410, and divides the internal space of the box body 410 into a first chamber 411 and a second chamber 412, and the first chamber 411 is connected to the liquid inlet 402. The baffle structure 430 is disposed in the first chamber 411 and is used to block floating objects and sediments in the liquid. The filter element 440 is disposed on the first partition 420, and connects the first chamber 411 and the second chamber 412, and filters the liquid entering the second chamber 412. By setting a baffle structure 430 in the first chamber 411, the baffle structure 430 can block floating objects and sediments in the liquid, and filter oil and larger particles in the liquid, completing the first stage of filtration; and the filter 440 on the first partition 420 filters the liquid entering the second chamber 412 again, completing the second stage of filtration; finally, the filtrate after two-stage filtration is output through the liquid outlet 404, so as to realize the recycling and utilization of the cleaning waste liquid, save cleaning water, and reduce the manufacturing cost of the tool. In addition, the filtering device 400 has a simple filtering structure, good filtering effect, and can perform more than two stages of filtering.

[0072] In order to facilitate the entry of the cleaning waste liquid into the box body 410, the box body 410 is provided with a liquid inlet channel 413, and the liquid inlet channel 413 is connected to the first chamber 411. The liquid inlet 402 of the filter device 400 is formed at the outer end of the liquid inlet channel 413, and the inner end of the liquid inlet channel 413 is provided with a filter screen 414, which performs preliminary filtration on the liquid after cleaning the tool and filters out large particles in the liquid.

[0073] In this embodiment, the baffle structure 430 includes a first baffle 432 and a second baffle 434. The top of the first baffle 432 is sealed and connected to the top surface of the first chamber 411, one side of the first baffle 432 is sealed and connected to the side surface of the first chamber 411, the other side of the first baffle 432 is sealed and connected to the side surface of the first partition 420, and the bottom of the first baffle 432 is spaced from the bottom surface of the first chamber 411. Since the bottom of the first baffle 432 is spaced from the bottom surface of the first chamber 411, a liquid level difference is generated, and floating objects such as oil stains located on the upper layer of the liquid are blocked by the first baffle 432, and most of the oil stains are deposited there.

[0074] Moreover, the second baffle 434 is disposed between the first baffle 432 and the filter element 440, the top of the second baffle 434 is spaced apart from the top surface of the first chamber 411, one side of the second baffle 434 is sealed and connected to the side surface of the first chamber 411, the other side of the second baffle 434 is sealed and connected to the side surface of the first partition 420, and the bottom of the second baffle 434 is sealed and connected to the bottom surface of the first chamber 411. Since the top of the second baffle 434 is spaced apart from the top surface of the first chamber 411, the larger particles of sediment located at the bottom of the liquid are blocked by the second baffle 434, so that the larger particles are precipitated there. It should be noted that, in other embodiments, the arrangement order of the first baffle 432 and the second baffle 434 can be changed, and the sediment is filtered first and then the floating objects are filtered; or, more than two first baffles 432 and more than two second baffles 434 are combined to filter the sediment and floating objects multiple times.

[0075] In this embodiment, the filter element 440 on the first partition 420 may be, but is not limited to, a 0.5 mm filter mesh structure, which can perform semi-fine filtration on the liquid entering the second chamber 412, thereby improving the filtration effect. Further, the filter element 440 is vertically mounted on the first partition 420, and filters the liquid processed by the first baffle 432 and the second baffle 434, and is not easily clogged, thereby ensuring good filtration performance and not requiring frequent replacement.

[0076] Furthermore, the top of the filter element 440 is kept at a certain distance from the top of the first partition 420, and the two side portions of the filter element 440 are also kept at a certain distance from the two side portions of the first partition 420, so as to be used as a reserved installation distance for screw locking, so as to facilitate the replacement of the filter element 440. Moreover, in order to further naturally precipitate the filter residue blocked by the filter element 440, the bottom of the filter element 440 is also kept at a certain distance from the bottom of the first partition 420. Therefore, the filter element 440 should be arranged in the middle of the first partition 420 as much as possible, so as to facilitate replacement and precipitation of the filter residue.

[0077] In this embodiment, the filter device 400 further includes a second partition 450 and a filter assembly 460. The second partition 450 is disposed in the second chamber 412, and the second chamber 412 is divided into a first filtrate chamber 415 and a second filtrate chamber 416. The first filtrate chamber 415 is connected to the first chamber 411 to store semi-fine filtrate. The filter assembly 460 is disposed in the housing 410, the input end of the filter assembly 460 is connected to the first filtrate chamber 415, and the output end of the filter assembly 460 is connected to the second filtrate chamber 416, and the semi-fine filtrate in the first filtrate chamber 415 is further filtered, and the filtered liquid is stored in the second filtrate chamber 416, and the fine filtration is finally completed. The filter assembly 460 includes a first liquid pump 462 and a filter 464 that are connected. Since the filter 464 can perform higher precision filtering, it is necessary to use the first liquid pump 462 to allow the liquid to pass through the filter 464, and the filtrate in the second filtrate chamber 416 can be directly used for tool cleaning.

[0078] Further, the first liquid pump 462 is provided on the housing 410, the input end of the first liquid pump 462 is inserted into the first filtrate chamber 415, and the output end of the first liquid pump 462 is connected to the input end of the filter 464. The filter 464 is provided on the housing 410, and the output end of the filter 464 is connected to the second filtrate chamber 416 through a pipeline. The first liquid pump 462 extracts the semi-fine filtrate in the first filtrate chamber 415 and pumps it into the filter 464, so that the liquid passes through the filter 464 under the action of water pressure to complete fine filtration. It can be understood that in other embodiments, the input end of the filter 464 is connected to the first filtrate chamber 415 through a pipeline, the output end of the filter 464 is connected to the input end of the first liquid pump 462, and the output end of the first liquid pump 462 is connected to the second filtrate chamber 416 through a pipeline. When the first liquid pump 462 is working, the semi-fine filtrate in the first filtrate chamber 415 first enters the filter 464 for fine filtration, and then is output to the second filtrate chamber 416 via the first liquid pump 462.

[0079] In this embodiment, a filter element is provided inside the filter 464, which can perform filtering with higher precision to meet the requirements of fine filtering.

[0080] The filter device 400 further includes a second liquid pump 470, which is disposed on the housing 410. The input end of the second liquid pump 470 is inserted into the second filtrate chamber 416, and the liquid outlet 404 is formed at the output end of the second liquid pump 470. The second filtrate chamber 416 is pumped out by the second liquid pump 470 to supply the tool for cleaning, thereby meeting the water pressure requirement for tool flushing. In this embodiment, the second liquid pump 470 is a high-pressure pump to improve the flushing effect of the tool.

[0081] Combination Figure 8 In order to monitor the liquid level in the second filtrate chamber 416 and avoid the situation where the second liquid pump 470 empties the filtrate therein without timely replenishing water, the filter device 400 further includes a first liquid level sensor 480, which is arranged on the housing and can detect the liquid level in the second filtrate chamber 416. The controller 230 is electrically connected to the first liquid level sensor 480 and the first liquid pump 462 of the filter device 400 respectively. The controller 230 controls the first liquid pump 462 to work according to the liquid level detected by the first liquid level sensor 480. When the first liquid level sensor 480 detects that the liquid level in the second filtrate chamber 416 is too low, the first liquid level sensor 480 feeds back the detection result to the controller 230. The controller 230 controls the first liquid pump 462 to work according to the received detection result, and extracts the liquid in the first filtrate chamber 415 for fine filtration, and replenishes the second filtrate chamber 416 with water to meet the water demand of the cleaning device 210. It is understandable that in other embodiments, the filter assembly 460 may automatically operate after the second liquid pump 470 pumps water for a period of time to replenish water to the second filtrate chamber 416 , that is, the filter device 400 may not use the first liquid level sensor 480 .

[0082] Furthermore, the first liquid level sensor 480 may be a pressure sensor or a photoelectric sensor.

[0083] In order to monitor the liquid level in the first filtrate chamber 415, the filter device 400 further includes a second liquid level sensor 490, which is disposed in the housing and can detect the liquid level in the first filtrate chamber 415. The device body 200 further includes an alarm 290, and the controller 230 is electrically connected to the alarm 290 and the second liquid level sensor 490 of the filter device 400, respectively. When the second liquid level sensor 490 detects that the liquid level in the first filtrate chamber 415 is too low, the second liquid level sensor 490 feeds back the detected result to the controller 230, and the controller 230 controls the alarm 290 to sound an alarm based on the received detection result, thereby reminding the user to add clean water to the first filtrate chamber 415.

[0084] Furthermore, the second liquid level sensor 490 may be a pressure sensor or a photoelectric sensor.

[0085] In order to discharge the filter residue in the box 410, a plurality of ball valves are provided at the bottom of the box 410, wherein one ball valve is located before the first baffle 432 and is used to discharge floating objects such as deposited oil, one ball valve is located between the first baffle 432 and the second baffle 434 and is used to discharge sediments such as larger particles, and one ball valve is located between the second baffle 434 and the filter element 440 and is used to discharge the filter residue. Furthermore, in order to facilitate sewage discharge, the extension pipe connected to the ball valve is tilted downward by 3° in the horizontal direction, and the sewage can be discharged by opening the ball valve.
