DETAILED DESCRIPTION

[0074] The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that it is easy for a person with ordinary skills in the prior art to implement these embodiments; however, the present invention can also be implemented in various different forms, so the present invention is not limited to the embodiments described below; in addition, in order to more clearly describe the present invention, parts that are not connected to the present invention will be omitted from the accompanying drawings.

[0075] Example

[0076] In order to solve the problem in the prior art that the clogged screen affects the recovery efficiency of the coolant in the waste mixture generated by machine tool processing, this embodiment provides a machine tool waste treatment device.

[0077] Reference Figure 1-7 The components include a screen drum 1, a main shaft 102, a driving member 103, an air injection slot 2, a driving member 201, an external air source 202, a guide channel 3 and a discharge structure 4.

[0078] The sieve drum 1 is a cylindrical cavity structure with an opening at the top, and a sieve plate 101 is arranged in the top thereof. The outer edge of the sieve plate 101 is arranged in an annular groove 1 on the inner wall of the top of the sieve drum 1, and the sieve plate 101 is coaxially distributed with the sieve drum 1, so that the annular groove can limit and guide the sieve plate 101.

[0079] The main shaft 102 is coaxially distributed with the sieve plate 101, and the two are fixedly connected. The top end of the main shaft 102 is arranged above the sieve plate 101 and is connected to a driving member 103. The driving member 103 is a motor, etc., which is used to drive the main shaft 102 to rotate forward and reverse, thereby driving the sieve plate 101 to rotate relative to the sieve drum 1; the driving member 103 is connected to the sieve drum 1 or an external bracket. In this embodiment, the driving member 103 is connected to the sieve drum 1 through a connecting rod, etc.

[0080] In order to facilitate the removal of materials that block the sieve plate 101, in this embodiment, an air jet slot 2 is provided below the sieve plate 101, and the top of the air jet slot 2 is an open structure, and its top is in contact with the bottom of the sieve plate 101; at the same time, the inner cavity of the air jet slot 2 is connected to the external air source 202 through a high-pressure pipe 203; the external air source 202 is used to provide high-pressure gas to the air jet slot 2 through the high-pressure pipe 203, thereby impacting the mesh on the sieve plate 101, so that the blockage inside is blown upward.

[0081] In order to prevent the blockages blown up from the bottom from splashing, in this embodiment, the guide channel 3 is arranged above the screen plate 101; the guide channel 3 has two ends, and is n-shaped as a whole, and its two ends are end 1 301 and end 2 302 respectively.

[0082] In order to avoid splashing of blockages and to make full use of the high-pressure airflow, in the present embodiment, both the end 1 301 and the end 2 302 are in contact with the top of the sieve plate 101, and the top projection of the end 1 301 coincides with the top projection of the top of the jet slot 2; that is, the cross-sectional shapes of the two are the same, so that the airflow ejected from the top of the jet slot 2 can enter the end 2 302 after passing through the sieve plate 1 101, and the corresponding blockage will also enter the inner cavity of the guide channel 3 and be guided to the end 2 302.

[0083] In order to prevent the high-pressure airflow from flushing the blockage in the guide channel 3 into the sieve plate 101 again, a sieve 303 is installed in the end 302. The aperture of the sieve 303 is smaller than the aperture of the sieve plate 101, so that the blockage is retained in the end 301, and the high-pressure airflow impacts the sieve plate 101 from top to bottom, thereby making full use of the high-pressure airflow and clearing the holes in the sieve plate 303 again.

[0084] In order to fully clear the blockage of the sieve plate 101, in this embodiment, the action end of the driving member 201 is connected to the outer walls of the jet groove 2 and the guide channel 3 respectively, so as to drive the jet groove 2 and the guide channel 3 to reciprocate in the radial direction of the sieve plate 101.

[0085] The driving member 201 is a structure such as a telescopic cylinder that can realize linear reciprocating motion. It drives the jet groove 2 and the guide channel 3 to reciprocate on a diameter of the screen plate 101. In order to prevent the blockage in the guide channel 3 from falling into the screen cylinder 1, the end 1 301 and the end 2 302 are distributed along the circumference of the screen plate 101.

[0086] Working principle:

[0087] During operation, the external air source 202, the driving member 103 and the driving member 201 are all opened synchronously. The driving member 201 drives the jet slot 2 and the guide channel 3 to reciprocate in the radial direction of the sieve plate 101. During the movement, the driving member 103 drives the sieve plate 101 to rotate through the main shaft 102, and the rotation direction is from the end 101 to the end 202. Then, the mixture of lubricating oil and waste chips is poured on the sieve plate 101, and the particles with large diameters are left on the sieve plate 101 and removed later, while the coolant passes through the sieve plate 101 and flows into the sieve drum 1. Some waste chips will block the screen in this process. When the jet slot 2 is accompanied by the reciprocating movement of the driving member 103, the high-pressure airflow generated by the external air source 202 passes through it. The top end rushes toward the sieve plate 101, and the blockage in the part of the sieve plate 101 impacted by the airflow can be blown into the end 301 arranged above the jet slot 2. After entering the end 301, it is swept by the high-pressure airflow entering the end 301 and flows to the end 2 302, and is blocked in the guide channel 3 by the sieve 303 on the end 2 302. The high-pressure airflow passes through the sieve 303 and continues to impact the sieve plate 101 from top to bottom to clear the blockage of the sieve plate 101. When the blockage in the guide channel 3 is full, it can be removed and cleaned in time. Among them, the high-pressure pipe 203 performs adaptive movement along with the movement of the driving member 201.

[0088] In the above process, the airflow first impacts the sieve plate 101 from bottom to top, so that the blockage inside it can be effectively cleared and collected in the guide channel 3, and then the high-pressure airflow is guided by the guide channel 3, and then impacts the sieve plate 101 from top to bottom, thereby achieving effective clearing of the sieve plate 101. Moreover, this is carried out during the working process of the sieve plate 101, thereby avoiding the disadvantages of pausing the sieve plate 101 for clearing, thereby improving the recovery efficiency of the coolant.

[0089] Secondly, in the above process, the rotation direction of the sieve plate 101 is from the end 1 301 to the end 2 302; that is, the part of the sieve plate 101 that has been cleaned by the high-pressure airflow from bottom to top will be cleaned again by the high-pressure airflow from top to bottom, thereby avoiding the disadvantage of large particle blockages falling into the sieve cylinder 1; the rotation movement of the sieve plate 101 allows the mixture of coolant and waste to be evenly sprinkled on the sieve plate 101, thereby avoiding the disadvantage of concentrated accumulation.

[0090] In order to further improve the recovery efficiency of the lubricating oil and avoid the drawbacks when cleaning the guide channel 3, in the present embodiment, a discharge structure 4 is further installed on the guide channel 3, and the discharge structure 4 is arranged on the side of the end 2 302 away from the end 1 301; the purpose of the discharge structure 4 is to discharge the blockage in the guide channel 3 as needed, so as to ensure the quality of hole cleaning; therefore, the discharge structure 4 only needs to meet the above requirements, for example, it is set as a movable door or other structure, which can be opened when needed, and its setting away from the end 1 301 makes it possible for the high-pressure airflow to assist in discharging the blockage in the guide channel 3 when it is opened to discharge the blockage, thereby improving the discharge efficiency.

[0091] Reference Figure 3 and 4 In order to reduce the workload of discharging the blockage, improve the discharge efficiency, and ensure the recovery efficiency of the coolant, in this embodiment, the discharge structure 4 includes an upper collecting bin 401, a screen 402, a discharge plate 403, a reset member 404, a discharge notch 104 and a closing plate 405.

[0092] Among them, the upper collecting bin 401 is in a cavity structure and is installed on the guide channel 3, and is located on the side of the end 2 302 away from the end 1 301; at the same time, the upper collecting bin 401 is connected to the inner cavity of the guide channel 3 through the guide window 406, and the screen 2 402 is installed in the guide window 406; and a discharge window 1 407 is provided on the side of the upper collecting bin 401 away from the end 1 301, and the top and bottom of the discharge window 1 407 are provided with slide grooves, and the top and bottom of the discharge plate 403 are respectively arranged in a slide groove; and the side wall of the discharge plate 403 away from the end 1 301 is connected to the movable end of the reset member 404; the fixed end of the reset member 404 is installed on the outer wall of the upper collecting bin 401.

[0093] like Figure 4The top transverse part of the guide channel 3 is an inclined channel, and the horizontal elevation of the connecting part of the inclined channel with the end 1 301 is greater than the horizontal elevation of the connecting part with the end 2 302. The upper collecting bin 401 is arranged on the side of the end 2 302 away from the end 1 301, and its top is connected to the inclined channel, and the connecting part and the inclined channel form a downwardly inclined structure, so that the blockage entering the guide channel 3 through the end 1 301 can be effectively entrained by the airflow into the upper collecting bin 401; the upper collecting bin 401 shares a wall with the end 2 302, and at A guide window 406 is provided on the wall so that the inner cavities of the two are connected. The high-pressure airflow entering the upper collecting bin 401 can pass through the screen 2 402 in the guide window 406 and enter the end 2 302, and rush to the screen plate 101 through the screen 1 303, while the blockage remains in the upper collecting bin 401; when necessary, the discharge plate 403 is driven by compressing the reset member 404 to open the discharge window 1 407. Then, under the impact of the high-pressure airflow, the blockage can be rushed out of the upper collecting bin 401 through the discharge window 1 407 by the high-pressure airflow, thereby achieving the removal of the blockage.

[0094] In order to realize the automatic removal of blockages, the following settings are also made:

[0095] A discharge notch 104 is provided on the screen drum 1, and a closing plate 405 is installed on a portion of the outer wall of the screen drum 1 on one side of the discharge notch 104 for discharging blockages; wherein the top and bottom portions of the closing plate 405 are coplanar with the top and bottom portions of the screen plate 101, respectively.

[0096] Among them, the size and installation position of the discharge notch 104 and the closing plate 405 meet the following requirements:

[0097] The guide channel 3, the jet groove 2 and the upper collecting bin 401 form a whole A. During the reciprocating motion of the whole A driven by the driving member 201, one end thereof can move out of the screen drum 1 through the discharge notch 104, and during the motion of the end out of the screen drum 1, the closing plate 405 can close the end 301, the end 302 and the part of the top of the jet groove 2 that moves out of the screen drum 1; and during the above motion process, when the whole A moves out of the screen drum 1 to a certain extent, a part of the discharge plate 403 has moved out of the screen drum 1, and the movable end of the reset member 404 contacts the inner wall of the screen drum 1, and during the continued motion, the reset member 404 is compressed, and the discharge plate 403 is driven by the reset member 404 to remain in the screen drum 1, so that the discharge window 40 7 is opened, and the opened part is outside the sieve cylinder 1, and at this time, the end 301, the end 302 and the part of the top of the jet slot 2 that moves out of the sieve cylinder 1 are all effectively closed, and the high-pressure airflow flows into the guide channel 3 through the unclosed part, and most of the airflow will flow out through the discharge window 407, thereby entraining the blockage to flow out of the upper collection bin 401 and being discharged from the sieve cylinder 1, thereby avoiding the disadvantages of manually clearing the blockage, improving the clearing efficiency, and helping to improve the recovery efficiency of the coolant; and only one end of the whole A moves out of the sieve cylinder 1, and part of it does not move out of the sieve cylinder 1, so that the top of the jet slot 2 is not completely closed, thereby ensuring that the high-pressure airflow can continue to flow into the guide channel 3 and flow out of the sieve cylinder 1 through the discharge window 407.

[0098] During the movement of the whole A toward the axis of the screen drum 1, the reset member 404 is out of contact with the inner wall of the screen drum 1, so that the discharge plate 403 is reset and the discharge window 407 is closed, so that the blockage remains in the upper collection bin 401 and is discharged during the subsequent movement.

[0099] In order to guide the flow, the side wall of the upper collecting bin 401 away from the second driving member 201 is an inclined wall, and the top of the inclined wall is away from the second driving member 201.

[0100] In the above process, the automatic collection and discharge of the blockage is effectively realized, and the hole cleaning efficiency of the screen plate 101 and the recovery efficiency of the coolant are improved.

[0101] In order to prevent the airflow from scouring the sieve plate 101 from being partially blocked and flowing into the sieve cylinder 1 to pollute the recovered coolant, the following settings are also made in this embodiment:

[0102] It includes a sieve plate 2 501, a driving rod 502, a lower collecting bin 5 connected to the outer wall of the air jet slot 2, etc.

[0103] Reference Figure 4 and 7The lower collecting bin 5 is an open-top structure, and its top is in contact with the bottom of the sieve plate 101, and the top projection of the top in the lower collecting bin 5 coincides with the top projection of the end 2 302, so that the airflow flowing from the end 2 302 to the sieve plate 101 will flow into the lower collecting bin 5 after flushing the sieve holes in the sieve plate 101, and correspondingly, the flushed blockages will also be collected in the lower collecting bin 5.

[0104] In order to discharge the high-pressure airflow and keep the blockage in the lower collecting bin 5, a discharge window 503 is provided on the side wall of the lower collecting bin 5 adjacent to the driving member 201, and a sieve plate 501 is provided in the discharge window 503, and both ends of the sieve plate 501 are rotatably connected to the inner wall of the discharge window 503 through a rotating shaft, and at least one rotating shaft is connected to the discharge window 503 through a torsion spring, and a stopper 504 is also provided in the discharge window 503. When there is no external force, the torsion spring causes the first end of the sieve plate 501 to move toward the stopper 504 until it fits with the stopper 504, and at this time the sieve plate 501 closes the discharge window 503.

[0105] Through the above-mentioned arrangement, the high-pressure airflow flowing into the lower collecting bin 5 will flow toward the discharge window 2 503, and the arrangement of the sieve plate 2 501 enables the blockage to be effectively intercepted in the lower collecting bin 5, while the high-pressure airflow flows out of the lower collecting bin 5, and the arrangement of the torsion spring enables the sieve plate 2 501 to always have a movement tendency toward the blocker 504, so that when the sieve plate 2 501 as a whole is impacted by the high-pressure airflow, it can always close the discharge window 2 503 to prevent the blockage from flowing out.

[0106] In order to automatically discharge the blockage in the lower collecting bin 5, in the present embodiment, the driving rod 502 is also connected to the closing plate 405, so as to drive the first end of the sieve plate 2 501 to move toward the inner cavity of the lower collecting bin 5 so as to open the discharge window 2 503 when the lower collecting bin 5 moves out of the sieve drum 1 along with the whole A through the discharge notch 104; wherein the size of the discharge notch 104 satisfies the requirement that the whole C composed of the whole A and the lower collecting bin 5 moves out of the sieve drum 1.

[0107] The side wall of the lower collecting bin 5 adjacent to the second driving member 201 is coplanar with the side wall of the upper collecting bin 401 adjacent to the second driving member 201. When the reset member 404 is initially compressed, the corresponding driving rod 502 also starts to drive the second sieve plate 501, so that the blockages in the upper collecting bin 401 and the lower collecting bin 5 can be discharged synchronously.

[0108] In some embodiments, in order to increase the air flow pressure for discharging the blockage, the discharge window 1 407 on the lower collecting bin 401 is opened for a period of time before the discharge window 2 503 on the lower collecting bin 401 is opened, so that a large amount of blockage accumulated in the guide channel 3 is discharged first.

[0109] That is, the end of the discharge window 2 503 arranged in the lower collecting bin 5 moves out of the sieve drum 1 along with the whole A through the discharge notch 104. In the process of moving out of the sieve drum 1, the driving rod 502 drives the end of the sieve plate 2 501 adjacent to the stopper 504 to open the sieve plate 2 501. When the sieve plate 2 501 is opened, the discharge window 1 407 is also opened. Then, the high-pressure airflow flows out from the unsealed part at the top of the jet slot 2 and flows to the end 301. After being guided by the guide channel 3, part of the air flows into the lower collecting bin 5 and flows out through the discharge window 1 407, and part of the air flows into the lower collecting bin 5 after passing through the end 302 and flows out through the discharge window 2 503, thereby realizing the effective discharge of the blockage. In this process, the air pressure output by the air source 202 can be increased to ensure the discharge effect of the blockage.

[0110] In order to guide and limit the flow guide channel 3 and further ensure the fit between the flow guide channel 3 and the sieve plate 101, the following settings are also made in this embodiment:

[0111] A guide rail 6 is also provided; wherein, the extension direction of the guide rail 6 is the same as the reciprocating motion direction of the guide channel 3, and one end thereof is sleeved on the main shaft 102 and limited by the main shaft 102, and the other end passes through the discharge notch 104 to be connected with the external structure, thereby maintaining the relative position with the screen drum 1; the guide channel 3 and the guide rail 6 are connected by a limiting component, etc., so that the guide channel 3 can only reciprocate in the extension direction of the guide rail 6, and the end 1 301 and the end 2 302 are respectively arranged on both sides of the guide rail 6.

[0112] Reference Figure 3 and 4 The n-shaped guide channel 3 is arranged across the guide rail 6 and is connected by a limit assembly. It can only reciprocate in the extension direction of the guide rail 6, and the movement direction is consistent with the movement direction of the driving member 201.

[0113] Through the above arrangement, the guide channel 3 can be effectively guided and maintained in contact with the sieve plate 101, thereby ensuring the clearing effect.

[0114] The connection between the guide rail 6 and the main shaft 102 enables the guide rail 6 to have a certain blocking effect, which facilitates the collection of waste on the screen plate 101 in the later stage.

[0115] In order to further improve the efficiency of clearing blockage, refer to the attached Figure 4 , Figure 4 The front end of the middle and upper collecting bin is in a cutaway state to observe the inner cavity structure; in this embodiment, the guide channel 3, the screen 1 303, the upper collecting bin 401, the screen 2 402, the discharge plate 403, the reset member 404, the lower collecting bin 5, the screen 2 501, the drive rod 502, the rotating shaft, the torsion spring, the block 504, and the guide rail 6 form a whole B, and the whole B is two; wherein:

[0116] The two guide rails 6 share one end, and the end is sleeved on the main shaft 102; and the two bodies B are symmetrically arranged about the vertical plane where the axis of the main shaft 102 is located, and share one end 1 301; that is, there is only one end 1 301.

[0117] That is, the end 301 of the two flow-guiding channels 3 is shared; Figure 4 , one end 1 301 and two end 2 302 form an M-shaped structure.

[0118] Through the above arrangement, the efficiency of clearing blockage can be effectively improved; wherein, the sizes of the discharge notch 104 and the closing plate 405 can effectively meet the requirements of discharging the aforementioned blockage from the screen drum 1 through the discharge window 1 407 and the discharge window 2 503 .

[0119] In some embodiments, in order to collect the blockage discharged from the screen drum 1, refer to the attached Figure 1 , 2 and 5, and is further provided with a material receiving box 106; the material receiving box 106 is installed on the outer wall of the screen cylinder 1; and the material receiving box 106 is connected to the inner cavity of the screen cylinder 1 through a discharge notch 104, and at the same time, the horizontal elevation of the bottom of the inner cavity of the material receiving box 106 is lower than the horizontal elevation of the bottom of the discharge notch 104, and is used to receive the materials discharged from the upper collecting bin 401 and the lower collecting bin 5.

[0120] Through the above arrangement, the materials discharged from the screen drum 1 through the discharge window 1 407 and the discharge window 2 503 can be effectively collected in the receiving box 1 106, thereby avoiding the disadvantage of overflow.

[0121] During the machining process, there are not only large-sized waste chips, but also small-sized powdery chips, such as powders with a density greater than that of the coolant, such as metal powders, etc., which are difficult to filter out by the sieve plate 101. In order to discharge and collect the powders with a density greater than that of the coolant, refer to the attached Figure 5 In this embodiment, the following settings are also performed:

[0122] An inverted conical enclosure 7 is installed in the sieve drum 1, and the bottom of the inverted conical enclosure 7 is connected to a guide tube 701, and the bottom of the guide tube 701 is arranged at a set distance above the bottom of the sieve drum 1, and an annular enclosure 708 is arranged outside the guide tube 701 without contacting it, and the top horizontal elevation of the annular enclosure 708 is greater than the bottom horizontal elevation of the guide tube 701.

[0123] Through the above arrangement, most of the coolant filtered by the sieve plate 101 will fall on the inverted cone-shaped enclosure 7, and then flow into the guide tube 701 under the action of gravity, and flow down along the inner wall of the guide tube 701 to the bottom of the inner cavity of the sieve tube 1, and be effectively encircled by the annular enclosure 708. The coolant flowing into the annular enclosure 708 can be left to stand in the annular enclosure 708, so that the powdery debris with a density greater than that of the coolant can settle on the bottom of the inner cavity of the sieve tube 1. The horizontal elevation of the top of the annular enclosure 708 is greater than the horizontal elevation of the bottom of the guide tube 701, so that the coolant in the annular enclosure 708 needs to overflow the annular enclosure 708 before it can flow into the space between the annular enclosure 708 and the inner wall of the sieve tube 1.

[0124] By arranging the bottom end of the guide tube 701 below the top of the annular enclosure 708, the coolant in the annular enclosure 708 can be effectively left to stand still, and powdery debris with a density greater than that of the coolant settles at the bottom of the sieve tube 1 in the annular enclosure 708, while the coolant without powdery debris needs to overflow the top of the annular enclosure 708 before it can flow out of the annular enclosure 708 and be recycled, thereby effectively improving the recovery quality of the coolant; wherein, the arrangement of the inverted cone enclosure 7 makes it impossible for most of the coolant flowing down through the sieve plate 101 to directly impact the coolant in the annular enclosure 708, thereby reducing the disturbance of the coolant in the annular enclosure 708 and helping to improve the sedimentation efficiency.

[0125] A liquid outlet hole is provided on the side wall at the bottom end of the sieve drum 1 to discharge the cooling liquid in the sieve drum 1 for recycling.

[0126] After long-term use of the equipment, a certain amount of powdery debris will accumulate in the annular enclosure 708, and a certain amount of powdery debris will settle at the bottom of the inner cavity of the screen drum 1, affecting the quality of coolant recovery. Therefore, in order to ensure the quality of coolant recovery, refer to the attached Figure 5 In this embodiment, the following settings are also performed:

[0127] A sewage plate 702 is provided at the bottom of the inner cavity of the sieve cylinder 1. The sewage plate 702 is circular, and its outer edge is arranged in the annular groove 2 in the side wall of the bottom end of the sieve cylinder 1. At the same time, the sewage plate 702 is coaxially distributed with the main shaft 102, but is not fixedly connected, and the bottom end of the main shaft 102 passes through the sewage plate 702 and is rotatably connected to the bottom of the sieve cylinder 1; in order to facilitate the rotation of the sewage plate 702 when necessary, in this embodiment, a ratchet 706 fixedly connected to the main shaft 102 is sleeved on the main shaft 102, and a ratchet pawl 707 cooperating with the ratchet 706 is installed on the top of the sewage plate 702;

[0128] When filtering, high-pressure gas impacts the sieve plate 101, and the driving member 103 drives the sieve plate 101 to rotate in the forward direction, and the ratchet 706 and the pawl 707 do not mesh with each other, and the coolant is allowed to settle at this time. When sewage is discharged, the driving member 103 drives the sieve plate 101 to rotate in the reverse direction, and the corresponding main shaft 102 drives the pawl 707 via the ratchet 706, and the pawl 707 drives the sewage plate 702 to rotate around the axis, and the sediment on the top of the sewage plate 702 is removed at this time.

[0129] In order to prevent the annular enclosure 708 from affecting the rotational movement of the sewage plate 702, in this embodiment, the annular enclosure 708 is hoisted in the screen drum 1 through a plurality of connecting arms, and its bottom is in contact with the top of the sewage plate 702 to ensure the sedimentation effect.

[0130] Secondly, a spiral material guide structure 703 is installed on the inner wall of the annular enclosure 708, and the bottom of the spiral material guide structure 703 is in contact with the top of the sewage discharge plate 702, so as to guide the material in the annular enclosure 708 out of the annular enclosure 708 and fall between the annular enclosure 708 and the inner wall of the sieve drum 1 during sewage discharge operation; and a guide plate 704 fixedly connected to the inner wall of the sieve drum 1 is provided between the inner wall of the bottom end of the sieve drum 1 and the annular enclosure 708; and a sewage discharge door 705 is provided on the part of the side wall of the sieve drum 1 adjacent to the guide plate 704.

[0131] That is, when filtering, the driving member 103 drives the sieve plate 101 to rotate in the direction from the end 1 301 to the end 2 302, and the drain plate 702 does not move, so that the coolant in the sieve drum 1 is allowed to settle, so that the powdery debris is separated from the coolant, and the quality of coolant recovery is improved; when the settled powdery debris needs to be removed, the driving member 103 is reversed, and the filtering operation is not performed at this time, and the drain operation is performed. The main shaft 102 drives the pawl 707 through the ratchet wheel 706 to drive the sewage plate 702 to rotate. During the rotation, the spiral material guide structure 703 does not move, and its bottom scrapes the sediment in the annular enclosure 708 and guides the annular enclosure 708 to fall between the annular enclosure 708 and the inner wall of the sieve drum 1. The guide plate 704 does not move, and scrapes the sediment between the annular enclosure 708 and the inner wall of the sieve drum 1. The sewage door 705 is opened, and the scraped sediment can be discharged through the sewage door 705.

[0132] In order to avoid the waste chips accumulated on the screen plate 101 affecting the quality of clearing, refer to the attached Figure 6 In this embodiment, the following settings are also performed:

[0133] An outlet structure 8 is also provided; wherein the outlet structure 8 includes an elongated outlet block 801, a conveyor belt 802, a second outlet notch 105, a transmission shaft 803, a linkage roller 804, a power tooth 805, a transmission tooth 806 and a transmission chain 807.

[0134] like Figure 5 and 6 The second discharge notch 105 is provided at the top of the screen drum 1 to discharge the waste on the top of the screen plate 101;

[0135] In order to discharge the large-particle waste on the sieve plate 101 out of the sieve drum 1 through the discharge notch 105, the first end of the discharge block 801 is close to the main shaft 102, and the second end is fixedly connected to a side wall of the discharge notch 105; and the bottom of the discharge block 801 is fitted with the top of the sieve plate 101, so as to prevent the material on the sieve plate 101 from passing over it and affecting the cleaning operation of the guide channel 3, etc.

[0136] A vertically arranged transmission shaft 803 is rotatably installed in the first end of the export block 801, and a vertically arranged linkage roller 804 is installed in the second end; a conveyor belt 802 is sleeved on the whole formed by the transmission shaft 803 and the linkage roller 804, and the side wall of the conveyor belt 802 away from the end 301 is coplanar with the side wall of the export block 801 away from the end 301, and is a vertical surface.

[0137] In order to drive the conveyor belt 802, a transmission tooth 806 fixedly connected to the transmission shaft 803 is sleeved on the top, and a power tooth 805 fixedly connected to the main shaft 102 is sleeved, and a transmission chain 807 is sleeved on the whole formed by the power tooth 805 and the transmission tooth 806.

[0138] That is, when the main shaft 102 rotates, the conveyor belt 802 can be driven to rotate via the transmission power teeth 805, the transmission teeth 806 and the transmission shaft 803; wherein, when the filtering operation is performed, the driving member 103 drives the sieve plate 101 to rotate in the positive direction via the main shaft 102, and the movement direction is from the guide block 801 to the end 301, and the main shaft 102 drives the conveyor belt 802 to rotate via the power teeth 805, the transmission teeth 806, the transmission shaft 803 and the transmission chain 807, refer to the attached Figure 6 At this time, the material in contact with the outlet block 801 and the conveyor belt 802 can be effectively driven by the conveyor belt 802 to flow to the discharge gap 105, and finally be discharged from the screen drum 1, thereby achieving the purpose of automatically removing the waste chips on the screen plate 101. The part of the waste chips on the top of the screen plate 103 that has been removed passes over the outlet block 801 and flows to the end 301.

[0139] In order to collect the waste chips discharged from the screen cylinder 1 through the conveyor belt 802, in this embodiment, the outlet structure 8 also includes a second material receiving box 107; the second material receiving box 107 is installed on the outer wall of the screen cylinder 1, and the second material receiving box 107 is connected to the inner cavity of the screen cylinder 1 through the second material discharge gap 105, and the bottom horizontal elevation of the second material receiving box 107 is lower than the bottom horizontal elevation of the second material discharge gap 105.

[0140] Through the above-mentioned arrangement, the waste chips on the screen plate 101 can be effectively collected in the receiving box 2 107; because a certain amount of coolant may still be adhered to the discharged waste chips, in order to separate them from the waste chips, a screen 3 108 is embedded on the side wall of the screen cylinder 1 above the bottom of the receiving box 2 107. Through the above-mentioned arrangement, the coolant in the receiving box 2 107 can be effectively separated from the waste chips and recovered.
