Abstract
Description
Technical Field
[0001] This invention relates to the field of putty powder grinding technology, and in particular to a grinding machine for putty powder production. Background Technology
[0002] Putty powder, mainly composed of talcum powder and glue, is used as a base material for repairing and leveling walls after being mixed and stirred. It is an indispensable building decoration material.
[0003] Currently, at least one production process for putty powder involves crushing, grinding, and mixing various raw materials in sequence. After the putty powder is mixed, it is packaged by a packaging machine for storage or sale. At present, due to the different production efficiencies of each process step, business owners will build several storage silos or tanks in the factory area to store the primary materials (hereinafter referred to as materials) obtained after each process step. When the materials in the silos need to be used, the materials are transferred to the equipment of the next process step by means of an elevator (such as a bucket elevator).
[0004] However, when materials are ground into powder, they easily absorb moisture from the air during transportation or storage, leading to clumping. Clumping can affect the crucial subsequent mixing process, such as causing segregation and other uneven mixing phenomena. Therefore, it is necessary to eliminate clumping before mixing. Grinding mills are one of the effective devices for eliminating clumping. However, current grinding mills are not ideal in handling clumped powder. For example, when processing clumped powder of different sizes simultaneously, the processing time is often based on the larger clumped powder, resulting in low efficiency.
[0005] Secondly, when processing agglomerated powder, a heating device is needed to dry the agglomerated powder in the grinding chamber in order to ensure the processing effect. However, due to the relatively sealed environment of the grinding chamber, the moisture generated during the drying process cannot be discharged. Over time, it will be impossible to ensure that the grinding chamber maintains a relatively dry environment, which will easily affect the work of eliminating agglomerates. Therefore, a fan is usually installed at the discharge end of the grinder (such as at the discharge pipe) to assist the gas in the grinding chamber to be discharged. However, after the grinding chamber is heated by the heating device, the gas inside it still maintains a certain temperature when it is discharged (that is, this part of the hot gas still has usable space). If it is discharged directly by the fan, it is also a waste of heat energy.
[0006] In summary, existing grinding machines need to be improved to solve the above problems. Summary of the Invention
[0007] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a grinding machine for putty powder production, which aims to solve the problems mentioned in the background technology.
[0008] The technical solution of the present invention is implemented as follows: a grinding machine for putting powder production includes a grinding machine body, having an abrasive chamber and a feed pipe and a discharge pipe communicating with the abrasive chamber;
[0009] An abrasive structure is disposed within an abrasive chamber, with the abrasive end of the abrasive structure abutting against the bottom wall of the abrasive chamber; it also includes a feeding mechanism mounted on the grinding machine body, the feeding mechanism comprising at least:
[0010] The feeding body is installed on the grinding machine body;
[0011] At least two primary grinding chambers are formed on the feed body and connected to the feed pipe through the discharge pipe;
[0012] The feeding hopper is installed on the feeding machine body and is used to feed materials into the primary grinding chamber;
[0013] The heat exchange chamber is formed on the feed machine body and is spaced apart from the primary grinding chamber. The feed machine body is provided with a hot air inlet and a hot air outlet that communicate with the heat exchange chamber.
[0014] Each primary grinding chamber is equipped with a crushing structure and a filtering structure, which can be controlled by a drive structure to rotate synchronously in a relatively opposite manner.
[0015] Preferably, the driving structure includes:
[0016] The first drive wheel is rotatably mounted on the feeder body and connected to the crushing structure via the first drive shaft.
[0017] The first transmission belt is used to drive the first drive wheels together.
[0018] The second drive wheel is rotatably mounted on the feeder body and drives the filter structure to rotate through the transmission assembly.
[0019] The second transmission belt is used to drive the connection between each of the second drive wheels;
[0020] The slide rail is fixedly mounted on the feeder body and is located between adjacent first drive wheels and / or adjacent second drive wheels;
[0021] The synchronous structure can be slidably connected to the slide rail, and has a through-hole for the first and second transmission belts to move, and a clamping structure that can be controlled by an electromagnetic component is provided in the through-hole.
[0022] Among them, any first drive wheel or any second drive wheel can be controlled by the first motor to rotate clockwise or counterclockwise.
[0023] Preferably, the synchronization structure includes:
[0024] Synchronizer, having a sliding cavity through which the slide rail passes;
[0025] The penetration opening consists of a first penetration opening and a second penetration opening spaced apart on the synchronizing body;
[0026] Receiving grooves are formed on the inner walls of both sides of the through opening;
[0027] The clamping block is slidably connected within the receiving groove;
[0028] The electromagnetic component includes a housing mounted on a synchronizing body and located on both sides of the through-hole. A piston shaft connected to a clamping block is slidably connected inside the housing. The piston shaft is connected to the housing via a return spring, and an electromagnet is installed inside the housing.
[0029] Preferably, the transmission assembly includes:
[0030] The first transmission gear is connected to the second drive wheel via the second transmission shaft and is rotatably mounted in the feeder body;
[0031] The second transmission gear is mounted on the filter structure and meshes with the first transmission gear.
[0032] By adopting the above technical solution: the grinding mill of the present invention sets up a feeding mechanism and uses the primary grinding chamber on the feeding mechanism to process the agglomerated powder in advance. The powder that meets the processing standards then enters the discharge pipe through the filter structure and enters the grinding chamber of the grinding mill. Therefore, the specifications (referring to the volume particle size) of the powder entering the grinding chamber are relatively uniform. Furthermore, since the agglomerated powder is pre-processed in the primary grinding chamber, when these uniformly sized agglomerated powders enter the grinding chamber, they can be completely processed by the grinding structure within a uniform time. Therefore, there is no need to consider the excessive difference in the specifications of the agglomerated powder, which would prolong the grinding time of the grinding structure, thereby improving production efficiency.
[0033] Secondly, the present invention is provided with multiple primary grinding chambers, and the crushing structure in each primary grinding chamber is synchronously controlled by the drive structure. After the drive structure is started, more agglomerated powder can be pre-processed, thereby ensuring the feeding of the grinding chamber. Moreover, the present invention utilizes the synchronous structure to enable the drive structure to simultaneously control the crushing structure and the filtering structure to rotate in opposite directions, thereby improving the pre-processing efficiency of agglomerated powder.
[0034] Preferably, the filter structure includes a filter cylinder rotatably disposed within the primary grinding chamber, the filter cylinder dividing the primary grinding chamber into a discharge chamber and a grinding chamber arranged coaxially at intervals, the discharge chamber being connected to the feed pipe via a discharge pipe, and the grinding chamber being connected to the feeding hopper; wherein, filter holes are distributed on the circumferential sidewall of the filter cylinder, and a pusher plate is fixedly connected to the sidewall of the filter cylinder, and the second transmission gear is fixed to the filter cylinder;
[0035] The pulverizing structure includes a stirring disc connected to a first drive shaft, and a number of loose material pieces that can move around the filter cylinder are fixedly connected at intervals on the stirring disc.
[0036] By adopting the above technical solution: the present invention provides a pusher plate on the filter structure. Therefore, when the loose material pieces of the crushing structure and the filter cylinder rotate in opposite directions, the pusher plate can guide the powder in the primary grinding chamber to move towards the loose material pieces, thereby improving the pretreatment efficiency of agglomerated powder.
[0037] Preferably, the feeder body has a plurality of drainage chambers, and the drainage chambers are slidably connected to piston plates controlled by a lifting control structure, the piston plates dividing each drainage chamber into an upper chamber and a lower chamber;
[0038] The feeding machine body is equipped with several air inlet check valves and air outlet check valves, and each air inlet check valve and each air outlet check valve is connected to the upper chamber or the lower chamber respectively;
[0039] The exhaust check valve is connected to the hot gas inlet via a regenerative pipe.
[0040] Preferably, the lifting control structure includes:
[0041] The equipment cavity is formed on the feeder body;
[0042] At least two support bases are installed at intervals inside the equipment cavity;
[0043] At least two worm gears are rotatably connected to the support base via a third drive shaft and are spaced apart;
[0044] The worm gear is rotatably connected inside the equipment cavity and can be controlled to rotate by a second motor. The worm gear is located between and engages with the worm wheel.
[0045] The drive disc is mounted on the third drive shaft and is located on the side of the support base away from the worm gear;
[0046] The drive disc is eccentrically connected to a slider, and a lifting rod is slidably connected to the slider inside the equipment cavity. Several lifting shafts are fixedly connected to the lifting rod, and each lifting shaft passes through the drainage cavity and is connected to the piston plate.
[0047] Preferably, the synchronous body is provided with a filter cavity, and the filter cavity is provided with an annular filter screen, which divides the filter cavity into an inner cavity and an outer cavity arranged coaxially;
[0048] The filter chamber is slidably connected to a limiting body by a limiting spring. The synchronizing body is provided with an air inlet and a sewage outlet communicating with the outer cavity and an exhaust outlet communicating with the inner cavity. The limiting body can be controlled by a reciprocating control structure and a limiting spring to reciprocate within the filter chamber.
[0049] The regenerative pipe includes a first pipe body connected between the exhaust check valve and the air inlet, and a second pipe body connected between the exhaust port and the hot air inlet.
[0050] Preferably, the reciprocating control structure includes:
[0051] The transmission cavity is formed within the synchronization body;
[0052] The drive gear is rotatably connected to the transmission cavity via the fourth transmission shaft and can be controlled by the third motor mounted on the synchronizer.
[0053] The transmission rod has one end fixedly connected to the limiting body, and the other end passes into the transmission cavity and is equipped with a rack that can mesh with the drive gear.
[0054] When the drive gear meshes with the rack, the transmission rod controls the limit body to open the drain port and close the exhaust port; when the drive gear separates from the rack, the limit body is controlled by the limit spring to close the drain port and open the exhaust port.
[0055] Preferably, the abrasive structure includes:
[0056] A support plate is installed on top of the abrasive chamber;
[0057] The support shaft is rotatably connected to the support plate;
[0058] The mounting plate is connected to the support shaft via a connecting shaft.
[0059] The mounting plate is fixedly connected with several grinding balls; the support shaft is fixedly connected with a driven gear and a linkage rod is longitudinally slidably connected to the grinding machine body. One end of the linkage rod passes through the drainage cavity and connects to the piston plate, and a transmission rack that meshes with the driven gear is provided on the linkage rod.
[0060] By adopting the above technical solution: the feeding body of the present invention is further provided with a diversion cavity. When the lifting control structure controls the piston plate in the diversion cavity to move up and down and reciprocate in the diversion cavity, the lower cavity can draw in the hot air in the grinding cavity and send it to the heat exchange cavity, thereby realizing the recovery of waste heat. When the hot air is sent into the heat exchange cavity, the powder in the primary grinding cavity can be heated by the heat exchange cavity, which can be used in conjunction with the crushing structure to pre-treat the agglomerated powder and improve efficiency. Secondly, the upper cavity of the present invention can draw in the hot air in the equipment cavity and send it into the heat exchange cavity, so as to recover and utilize the heat generated by the operation of the second motor.
[0061] Meanwhile, when the hot air in the abrasive chamber is extracted, a negative pressure is formed in the abrasive chamber. The abrasive chamber is connected to the primary grinding chamber through the discharge pipe and the feed pipe. Therefore, the powder in the primary grinding chamber can enter the abrasive chamber more efficiently by relying on its own gravity and the negative pressure formed in the abrasive chamber.
[0062] The present invention also includes a filter chamber in the synchronous body. The hot air discharged from the drainage chamber is first filtered in the filter chamber and then sent into the heat exchange chamber to prevent impurities from entering the heat exchange chamber and adhering to the inner wall of the heat exchange chamber, thus affecting the heat exchange effect on the primary grinding chamber.
[0063] Furthermore, the present invention can control the start of the abrasive structure during the reciprocating lifting and lowering of the fluid by means of a linkage rod, thus eliminating the need for a separate driver to operate the abrasive structure. Attached Figure Description

Specifically, in this embodiment, the abrasive chamber 101... The system consists of a bottom cavity 100a connected to the bottom and a connecting cavity 100b connected to the bottom cavity 100a and the feed pipe 101. The bottom surface of the bottom cavity 100a is curved. The discharge cavity 103 is connected to the bottom cavity 100a. The powder enters the connecting cavity from the feed pipe and falls into the bottom cavity 100a. After processing, the discharge valve is opened and the powder is discharged from the discharge cavity and the discharge pipe 102 through the discharge screen 104. In this embodiment, it is preferred that the discharge cavity 103 is located at the lower part of the bottom cavity 100a.
[0081] refer to Figure 1 , Figure 3 In this embodiment, a heater 105 is also installed on the grinding machine body 10 for heating the bottom cavity.
[0082] refer to Figures 3-5 In this embodiment, the abrasive structure is located inside the abrasive cavity 100, and the abrasive end of the abrasive structure abuts against the bottom wall of the abrasive cavity. It consists of an abrasive gear 20, an abrasive support shaft 21 that supports the rotation of the abrasive gear 20 and is rotatably connected to the abrasive cavity 100, and a grinding ball frame 22 fixedly connected to the abrasive support shaft 21. The grinding ball frame 22 has several grinding balls 23 on the side near the bottom cavity 100a. The abrasive gear 20 meshes with an abrasive rack 24. The abrasive rack 24 is slidably mounted on the grinding machine and is controlled to move up and down by a hydraulic cylinder 25. When the abrasive rack moves up and down, the abrasive gear drives the support shaft 21 to rotate and drives the grinding ball frame 22 to swing around the support shaft. The grinding balls 23 process the powder in the bottom cavity.
[0083] refer to Figures 1-8 This embodiment also includes a feeding mechanism mounted on the grinding mill body 10, the feeding mechanism comprising at least:
[0084] The feed body 30 is installed on the grinding body 10;
[0085] Three primary grinding chambers 31 are formed on the feed body 30 and connected to the feed pipe 101 through the discharge pipe 31a. In this embodiment, three primary grinding bodies 31b are connected to the feed body 30, and the primary grinding chambers 31 are disposed in each primary grinding body 31b.
[0086] The feeding hopper 32 is installed on the feeding machine body 30 (primary grinding body 31b) and is used to feed material into the primary grinding chamber 31;
[0087] The heat exchange chamber 33 is formed on the feed body (primary grinding body 31b) and is spaced apart from the primary grinding chamber 31. The feed body (primary grinding body 31b) is provided with a hot air inlet 33a and a hot air outlet 33b that communicate with the heat exchange chamber 33. The hot air inlet 33a can be connected to a heating pipe so that hot air enters the heat exchange chamber and heats the primary grinding chamber 31.
[0088] Each primary grinding chamber 31 is equipped with a crushing structure and a filtering structure, which can be controlled by a drive structure to rotate synchronously in a relatively opposite manner.
[0089] In this embodiment, the primary grinding chamber 31 and the heat exchange chamber 33 are two circular chambers arranged coaxially and spaced apart. Specifically, the primary grinding chamber 31 has a circular cross-section, and the heat exchange chamber 33 has an annular cross-section.
[0090] In this embodiment: the driving structure includes:
[0091] The first drive wheel 41 is rotatably mounted on the feed body (primary grinding body 31b) and connected to the crushing structure via the first drive shaft 41a;
[0092] The first transmission belt 41b is connected between each of the first drive wheels 41;
[0093] The second drive wheel 42 is rotatably mounted on the feed body (the primary grinding body 31b, with the second drive wheel 42 located at the bottom of the primary grinding body 31b), and drives the filter structure to rotate via the transmission assembly.
[0094] The second transmission belt 42a is connected between each of the second drive wheels 42.
[0095] The slide rail 43 is fixedly mounted on the feed body (primary grinding body 31b) and is located between adjacent first drive wheels 41 and adjacent second drive wheels 42;
[0096] The synchronization structure 44 is slidably connected to the slide rail 43 and has a through-hole for the first transmission belt 41b and the second transmission belt 42a to move, and a clamping structure that can be controlled by an electromagnetic component is provided in the through-hole.
[0097] In this embodiment, any first drive wheel 41 or any second drive wheel 42 can be controlled by the first motor 45 to rotate clockwise or counterclockwise. The first motor 45 controls the rotation of the first drive wheel 41.
[0098] In this embodiment: the synchronization structure 44 includes:
[0099] Synchronizer 440 has a slide cavity 441 through which slide rail 43 passes;
[0100] The through-hole is composed of a first through-hole 44a and a second through-hole 44b spaced apart on the synchronizing body 440;
[0101] Receiving grooves are formed on the inner walls of both sides of the through opening;
[0102] Clamping block 442 is slidably connected within the receiving groove;
[0103] The electromagnetic component includes a housing 443 mounted on a synchronizing body 440 and located on both sides of the through-hole. A piston shaft 444, slidably connected to a clamping block 442, is slidably connected within the housing 443. The piston shaft 444 is connected to the housing 443 via a return spring 445, and an electromagnet 446 is installed within the housing. In this embodiment, the piston shaft 444 is equipped with a magnet 447 with the opposite magnetic pole to that of the electromagnet 446. When the electromagnet is energized, the piston shaft moves away from the electromagnet, causing the clamping block to approach the drive belt. Conversely, the piston shaft is driven away from the drive belt by the return spring. It is worth noting that, to avoid damaging the teeth on the drive belt, the size of the clamping block does not exceed the size between two adjacent teeth of the drive belt, so that when the clamping block approaches the drive belt, it can be positioned between adjacent teeth.
[0104] In this embodiment: the transmission assembly includes: a first transmission gear 51, which is connected to a second drive wheel 42 via a second transmission shaft 52, and is rotatably disposed inside the feed body (primary grinding body 31b);
[0105] The second transmission gear 53 is mounted on the filter structure and meshes with the first transmission gear 51. The second transmission gear 53 is rotatably mounted on the primary grinding body through the limiting ring 53a.
[0106] In this embodiment, the filtration structure includes a filter cylinder 60 rotatably disposed within the primary grinding chamber 31. The filter cylinder 60 divides the primary grinding chamber 31 into a discharge chamber and a grinding chamber arranged coaxially at intervals. The discharge chamber is connected to the feed pipe via a discharge pipe 31a, and the grinding chamber is connected to the feeding hopper 32. Filter holes (which can be a cylindrical structure woven around a filter screen) are distributed on the circumferential sidewall of the filter cylinder 60, and a pusher plate 60a is fixedly connected to the sidewall of the filter cylinder 60. The second transmission gear 53 is fixed to the filter cylinder 60, and the filter cylinder 60 is connected to the second transmission gear 53 via an annular rotating part 61a. A sealing ring may be provided at the mating position between the annular rotating part 61a and the primary grinding body.
[0107] The pulverizing structure includes a stirring disc 62 connected to the first drive shaft 41a, and a plurality of loose material pieces 63 that can move around the filter cylinder 60 are fixedly connected at intervals on the stirring disc 62.
[0108] In this embodiment, the first transmission gear 51 is also meshed with a third transmission gear 54. The third transmission gear 54 is connected to an anti-blocking disc 55 located between the feed hopper and the primary grinding chamber via a transmission shaft. The anti-blocking disc 55 is provided with an anti-blocking blade 56.
[0109] refer to Figures 1-8 The principle of this embodiment is as follows: agglomerated powder is poured into the feed hopper and enters the primary grinding chamber for primary grinding. During primary grinding, the first motor controls the rotation of the stirring disc and uses the material dispersing plate to break up the agglomerated powder. Qualified powder is screened by the filter cylinder and enters the discharge chamber, and is sent into the grinding chamber through the discharge pipe and feed pipe. The grinding structure in the grinding chamber is controlled by the hydraulic cylinder to further process the powder. After the processing is completed, the powder passes through the discharge screen at the discharge chamber and is discharged from the discharge pipe, thus completing the elimination of powder agglomeration.
[0110] When agglomerated powder is in the primary grinding chamber, hot air can be supplied to the heat exchange chamber through an external heating pipe to heat the powder in the primary grinding chamber, thereby assisting the crushing structure in breaking up the agglomerated powder more quickly. At the same time, to further improve efficiency, when the first motor controls the crushing structure to start through the first drive wheel, the electromagnet on the synchronization structure can be energized, and the clamping block clamps the first and second transmission belts. In this way, the first motor can simultaneously control the first and second drive wheels, and the second drive wheel controls the rotation of the filter cylinder on the primary grinding body. Since the second drive wheel drives the filter cylinder to rotate through the first and second transmission gears, the rotation direction of the filter cylinder and the stirring disc is opposite. The pusher plate set on the filter cylinder can make the crushing structure process the agglomerated powder more quickly, thereby improving the processing efficiency.
[0111] It is worth mentioning that this embodiment also has an anti-blocking disc driven by a third transmission gear. The anti-blocking disc is located at the connection between the feed hopper and the primary grinding chamber. When the second drive wheel rotates, it drives the second transmission gear to rotate through the first transmission gear and controls the rotation of the anti-blocking disc. The anti-blocking blades on the anti-blocking disc can prevent the agglomerated powder from blocking the connection between the feed hopper and the primary grinding chamber, ensuring normal feeding.

[0123] In this embodiment, a support rail 86a is provided inside the equipment cavity, and the two ends of the lifting rod 86 slide along the support rail.
[0124] In this embodiment: the synchronizing body 440 is provided with a filter cavity, and the filter cavity is provided with an annular filter 9. The annular filter 9 divides the filter cavity into an inner cavity 90 and an outer cavity 91 arranged coaxially.
[0125] The filter chamber is slidably connected to a limiting body 93 by a limiting spring 92. The synchronizing body 440 is provided with an air inlet 94 and a sewage outlet 95 communicating with the outer cavity 91, and an exhaust outlet 96 communicating with the inner cavity 90. The limiting body 93 can be controlled to reciprocate within the filter chamber by the reciprocating control structure and the limiting spring 92.
[0126] The regenerating pipe includes a first pipe body 741 connected between the exhaust check valve 73 and the air inlet 94, and a second pipe body 742 connected between the exhaust port 96 and the hot gas inlet 33a. The feeder body 30 is provided with a chamber 30a, which is connected to the first pipe body 741 so that the gas discharged from the exhaust check valve enters the first pipe body from the chamber.
[0127] In this embodiment: the reciprocating control structure includes:
[0128] The transmission cavity 97 is formed within the synchronizing body 440;
[0129] The drive gear 971 is rotatably connected to the transmission cavity 97 via the fourth transmission shaft 972 and can be controlled by the third motor 973 mounted on the synchronizer 440;
[0130] The transmission rod 974 has one end fixedly connected to the limiting body 93, and the other end passes into the transmission cavity 97 and is provided with a rack 975 that can mesh with the drive gear 971.
[0131] When the drive gear 971 meshes with the rack 975, the transmission rod 974 controls the limit body 93 to open the drain port 95 and close the exhaust port 96; when the drive gear 971 separates from the rack 975, the limit body 93 is controlled by the limit spring 92 to close the drain port 95 and open the exhaust port 96.
[0132] In this embodiment, the drain outlet is connected to a drain pipe 977. A baffle 930 is provided on the side of the limiting body 93 near the drain outlet 95. The baffle 930 is provided with a misalignment port 931. When the limiting body 93 descends, the misalignment port 931 communicates with the drain outlet 95. When the limiting body 93 rises, the misalignment port 931 is misaligned with the drain outlet 95. At this time, the baffle 930 closes the drain outlet.
[0133] In this embodiment: the abrasive structure includes:
[0134] Support plate 990 is installed on top of the abrasive chamber;
[0135] Support shaft 991 is rotatably connected to support plate 990;
[0136] Mounting plate 992 is connected to support shaft 991 via connecting shaft 993;
[0137] The mounting plate 992 is fixedly connected with a plurality of grinding balls 994; the support shaft 991 is fixedly connected with a driven gear 995, and a linkage rod 996 is longitudinally slidably connected on the grinding machine body 10. One end of the linkage rod 996 passes through the drainage cavity and is connected to the piston plate 71, and a transmission rack 997 that meshes with the driven gear 995 is provided on the linkage rod 996.
[0138] refer to Figures 9-14 The principle of this embodiment is as follows: To improve heat utilization, when the second motor drives the worm gear, the worm gear drives the worm wheel to rotate, and the worm wheel drives each drive disc to rotate, so as to... Figure 13For example, when the drive disc rotates, the height of the slider changes, controlling the lifting rod to rise or fall. When the lifting rod rises, the piston plate is controlled to rise via the lifting shaft, and the lower chamber draws in hot air from the abrasive chamber. When the lifting rod falls, the piston plate is controlled to fall via the lifting shaft, and the lower chamber discharges the hot air through the exhaust one-way valve. Similarly, when the lifting rod falls, the upper chamber draws in the hot air generated by the second motor from the equipment chamber, and when the lifting rod rises, the upper chamber discharges the hot air through the exhaust one-way valve.
[0139] The hot air discharged from the upper and lower chambers is sent into the filter chamber of the synchronizing body. After being filtered by the annular filter screen, it is sent into the heat exchange chamber through the exhaust port and heats the primary grinding chamber, thereby completing the recovery of waste heat.
[0140] It is worth mentioning that the filter chamber set in this embodiment can filter impurities, preventing impurities from entering and covering the inner wall of the heat exchange chamber and affecting the heat exchange effect on the primary grinding chamber.
[0141] Secondly, when the third motor controls the drive gear to rotate, the drive gear meshes with the rack, controlling the limit body to close the exhaust port and open the drain port. At this time, the impurities in the filter chamber are discharged through the drain port. When the drive gear separates from the rack, the limit body is controlled by the limit spring to rise and open the exhaust port while closing the drain port. At this time, hot air can enter the heat exchange chamber normally. Therefore, this embodiment can clean the filter chamber itself to ensure the filtration effect.
[0142] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
