Description

Technical Field

[0001] This utility model relates to the field of Raymond mill technology, specifically to an air intake mechanism for a Raymond mill. Background Technology

[0002] Raymond mill, also known as suspension roller mill or pendulum mill, is a type of equipment widely used in metallurgy, building materials, chemical industry and mining. It is mainly used for fine powder processing. It drives the load arm to rotate at high speed through a rotating shaft gear, and uses the shearing and extrusion force between the roller and the annular grinding disc to crush materials.

[0003] Patent No. 202121214540.1 discloses an air intake mechanism for a Raymond mill. When external air is introduced, it can pass through the outer frame and then through the rotating plate into the interior of the bottom shell. At the same time, the user can install a purification shell inside the mounting shell.

[0004] However, the existing air intake mechanism of Raymond mills uses a blower to force air into the Raymond mill through the air intake duct, and the amount of air entering the Raymond mill is fixed, which cannot be flexibly adjusted according to work requirements. At the same time, the air filter structure is set inside the air intake duct, but after long-term use, a lot of dust and foreign objects will accumulate on the filter structure, which requires the staff to disassemble the air intake duct to remove it. The operation is cumbersome, and the disassembly and cleaning of the filter structure is inconvenient. Therefore, an air intake mechanism for Raymond mills is designed. Utility Model Content

[0005] The main purpose of this utility model is to provide an air intake mechanism for a Raymond air conditioner. This utility model solves the problems of existing Raymond air conditioner air intake mechanisms being unable to adjust the amount of air entering the Raymond air conditioner according to needs, and also making it inconvenient to disassemble and clean the filter frame in the air intake duct, by setting up a motor A, gear A, gear B, drive rod, motor B, air volume sensor, controller, fan blade, fixing component, outer frame and support rod.

[0006] The technical solution adopted by this utility model to solve its technical problem is an air intake mechanism for a Raymond mill, including a Raymond mill body. An air intake duct for allowing external gas to enter the Raymond mill body is screwed to the outside of the Raymond mill body. A motor A providing power is bolted to the outside of the air intake duct, and a support rod is keyed to the power output end of motor A. A gear B is sleeved on the end of the support rod away from motor A, and gear A is externally meshed with gear B. A drive rod for transmission is engaged inside gear A, and a screw is fixed to the outside of the drive rod. The fan blades allow external air to enter the air inlet duct. An airflow sensor for detecting the wind speed entering the Raymond machine body is fixed to the inner wall of the air inlet duct by screws. A controller for receiving signals from the airflow sensor is fixed to the outer wall of the air inlet duct by screws. A filter frame for filtering the gas is inserted into the end of the air inlet duct away from the Raymond machine body. Filter screens A and B for gas processing are fixed to the inner side of the filter frame by screws, with filter screen A located to the left of filter screen B. An outer frame is fixed to the outer periphery of the air inlet duct by screws, and a fixing component for fixing the filter frame is provided inside the outer frame.

[0007] By adopting the above technical solution, when gas is to enter the Raymond machine body, the motor A outside the air inlet duct converts the received electrical energy into mechanical energy under the action of the controller. Then, the motor A drives the gear B outside the support rod to rotate. Then, the gear B drives the drive rod inside the gear A to rotate. Then, the drive rod drives the external fan blades to rotate, so that the external gas enters the air inlet duct. Then, the air volume sensor inside the air inlet duct transmits the air volume signal to the controller outside the air inlet duct. Then, the controller controls the speed of the motor A, so as to facilitate the adjustment of the air volume entering the Raymond machine body.

[0008] When external air enters the air inlet duct, filters A and B in the filter holder at the end of the air inlet duct filter out impurities in the air. Then, the fixing components in the outer frame release the filter holder, and the filter holder is then removed from the air inlet duct. After cleaning the filter holder, it is put back into the end of the air inlet duct, and then the fixing components in the outer frame fix the filter holder, which facilitates the disassembly and cleaning of the filter holder in the air inlet duct.

[0009] Specifically, the fixing assembly includes a motor B, a reciprocating sleeve A, a transmission plate A, a bidirectional lead screw, a transmission plate B, a reciprocating sleeve B, a limiting block A, and a limiting block B. The bottom of the outer frame is bolted to the motor B, which provides power, and the power output end of the motor B is keyed to the bidirectional lead screw. The bidirectional lead screw is externally threaded to the reciprocating sleeve A and the reciprocating sleeve B, with the reciprocating sleeve A located on the upper side of the reciprocating sleeve B. The transmission plate A is welded to the outer side of the reciprocating sleeve A, and a limiting block A that contacts the filter frame is screwed to one side of the transmission plate A. The transmission plate B is welded to the outer side of the reciprocating sleeve B, and a limiting block B that contacts the filter frame is welded to the outer side of the transmission plate B.

[0010] By adopting the above technical solution, when the filter frame needs to be disassembled, the motor B at the bottom of the outer frame converts the received electrical energy into mechanical energy under the action of the controller. The motor B drives the bidirectional lead screw to rotate. Then, the reciprocating sleeve A and the reciprocating sleeve B outside the bidirectional lead screw are both limited by the external structure. Then, the reciprocating sleeve A drives the limiting block A outside the transmission plate A to move, and the reciprocating sleeve B drives the limiting block B outside the transmission plate B to move, so that the limiting block A and the limiting block B are separated from the filter frame respectively, thereby facilitating the release of the filter frame from fixation.

[0011] Both motor A and motor B are servo motors, and a bearing is installed at the end of the bidirectional lead screw away from motor B.

[0012] Specifically, a fixing rod is welded inside the air inlet duct, and a bushing that stabilizes the rotation of the drive rod is fixed to the inner side of the fixing rod with screws.

[0013] By adopting the above technical solution, when gear A drives the drive rod to rotate, the drive rod rotates in the bushing inside the fixed rod, thereby improving the stability of the drive rod rotation. In addition, multiple through holes are opened on the surface of the fixed rod, so that the gas can flow smoothly in the air inlet.

[0014] Specifically, the filter frame is screwed to a rubber pad that contacts the inside of the air inlet duct.

[0015] By adopting the above technical solution, when the filter frame is placed in the air inlet duct, the rubber pad on the outside of the filter frame is tightly connected to the inside of the air inlet duct, thereby improving the sealing between the air inlet duct and the filter frame.

[0016] Specifically, the bottom of the air inlet duct is bolted with a fixing plate that supports the air inlet duct.

[0017] By adopting the above technical solution, the fixing plate installed at the bottom of the air intake duct supports the air intake duct and improves the stability of the air intake duct.

[0018] Specifically, the input terminals of motor B, motor A, air volume sensor, and controller are all electrically connected to the power supply terminal of an external power source.

[0019] By adopting the above technical solution and connecting to an external power source, the electrical equipment can operate normally.

[0020] The beneficial effects of this utility model are:

[0021] (1) The air intake mechanism of the Raymond machine described in this utility model, when gas is to enter the Raymond machine body, the motor A outside the air intake duct is converted into mechanical energy by the controller. Then the motor A drives the gear B outside the support rod to rotate. Then the gear B drives the drive rod inside the gear A to rotate. Then the drive rod drives the external fan blade to rotate, so that the external gas enters the air intake duct. Then the air volume sensor inside the air intake duct transmits the air volume signal to the controller outside the air intake duct. Then the controller controls the speed of the motor A, so as to facilitate the adjustment of the air volume entering the Raymond machine body.

[0022] (2) The air intake mechanism of the Raymond machine described in this utility model, when external gas enters the air intake duct, filter screens A and B in the filter frame at the end of the air intake duct filter the impurities in the gas. Then the fixing component in the outer frame releases the filter frame, and then the filter frame is taken out from the air intake duct. After cleaning the filter frame, the filter frame is put back into the end of the air intake duct. Then the fixing component in the outer frame fixes the filter frame, which facilitates the disassembly and cleaning of the filter frame in the air intake duct. Attached Figure Description

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] In order to disassemble and clean the filter frame 8 inside the air inlet duct 2, as an embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the air intake mechanism of a Raymond mill according to this utility model includes a Raymond mill body 1. An air intake duct 2 for allowing external gas to enter the Raymond mill body 1 is screwed onto the outside of the body 1. A motor A4 for providing power is bolted to the outside of the air intake duct 2, and a support rod 16 is keyed to the power output end of the motor A4. A gear B15 is sleeved on the end of the support rod 16 away from the motor A4, and gear A14 is externally meshed with gear B15. A drive rod 10 for transmission is internally engaged with gear A14, and a screw is screwed onto the outside of the drive rod 10 for allowing external gas to enter. The air inlet duct 2 has a fan blade 9 inside. The air inlet duct 2 has an air volume sensor 13 that detects the wind speed entering the Raymond machine body 1, which is fixed to the inner wall of the air inlet duct 2 with screws. The air inlet duct 2 has a controller 3 that receives the signal from the air volume sensor 13, which is fixed to the outer wall of the air inlet duct 2 with screws. The air inlet duct 2 has a filter frame 8 for filtering gas, which is fixed to the inner wall of the filter frame 8 with screws. The filter frame 8 has a filter screen A17 and a filter screen B19 for processing gas, and the filter screen A17 is located to the left of the filter screen B19. The air inlet duct 2 has an outer frame 5, which is fixed to the outer periphery with screws. The outer frame 5 has a fixing component 20 for fixing the filter frame 8 inside.

[0031] In use, when gas is to enter the Raymond machine body 1, the motor A4 outside the air inlet duct 2 converts the received electrical energy into mechanical energy under the action of the controller 3. Then, the motor A4 drives the gear B15 outside the support rod 16 to rotate. Then, the gear B15 drives the drive rod 10 inside the gear A14 to rotate. Then, the drive rod 10 drives the external fan blade 9 to rotate, so that the external gas enters the air inlet duct 2. Then, the air volume sensor 13 inside the air inlet duct 2 transmits the air volume signal to the controller 3 outside the air inlet duct 2. Then, the controller 3 controls the speed of the motor A4, so as to facilitate the adjustment of the air volume entering the Raymond machine body 1.

[0032] When external gas enters the air inlet duct 2, the filter screens A17 and B19 in the filter frame 8 at the end of the air inlet duct 2 filter the impurities in the gas. Then, the fixing component 20 in the outer frame 5 releases the filter frame 8 from the air inlet duct 2. After cleaning the filter frame 8, the filter frame 8 is put back into the end of the air inlet duct 2. Then, the fixing component 20 in the outer frame 5 fixes the filter frame 8, which facilitates the disassembly and cleaning of the filter frame 8 in the air inlet duct 2.

[0033] To release the filter holder 8 from its fixation, for example, as follows: Figure 4 As shown, this utility model also includes the fixing component 20, which includes a motor B25, a reciprocating sleeve A21, a transmission plate A22, a bidirectional lead screw 23, a transmission plate B26, a reciprocating sleeve B24, a limiting block A6, and a limiting block B7. The bottom of the outer frame 5 is bolted to the motor B25, which provides power, and the power output end of the motor B25 is keyed to the bidirectional lead screw 23. The bidirectional lead screw 23 is externally threaded to the reciprocating sleeve A21 and the reciprocating sleeve B24, and the reciprocating sleeve A21 is located on the upper side of the reciprocating sleeve B24. The transmission plate A22 is welded to the outside of the reciprocating sleeve A21, and a limiting block A6 that contacts the filter frame 8 is screwed to one side of the transmission plate A22. The transmission plate B26 is welded to the outside of the reciprocating sleeve B24, and a limiting block B7 that contacts the filter frame 8 is welded to the outside of the transmission plate B26.

[0034] When the filter frame 8 needs to be disassembled during use, the motor B25 at the bottom of the outer frame 5 converts the received electrical energy into mechanical energy under the action of the controller 3. The motor B25 drives the bidirectional lead screw 23 to rotate. Then, the reciprocating sleeves A21 and B24 outside the bidirectional lead screw 23 are both limited by the external structure. Then, the reciprocating sleeve A21 drives the limiting block A6 outside the transmission plate A22 to move, and the reciprocating sleeve B24 drives the limiting block B7 outside the transmission plate B26 to move, so that the limiting block A6 and the limiting block B7 are separated from the filter frame 8 respectively, thereby facilitating the release of the filter frame 8 from the fixation.

[0035] Both motor A4 and motor B25 are servo motors, and a bearing is provided at the end of the bidirectional lead screw 23 away from motor B25.

[0036] To improve the stability of the rotation of the drive rod 10, for example, such as Figure 2 As shown, the present invention also includes a fixing rod 12 welded inside the air inlet duct 2, and a bushing 11 that stabilizes the rotation of the drive rod 10 is fixed to the inner side of the fixing rod 12 with screws.

[0037] When in use, when gear A14 drives the drive rod 10 to rotate, the drive rod 10 rotates in the bushing 11 inside the fixed rod 12, thereby improving the stability of the rotation of the drive rod 10. In addition, multiple through holes are opened on the surface of the fixed rod 12 to allow gas to flow smoothly in the air inlet duct 2.

[0038] To improve the sealing between the air inlet duct 2 and the filter frame 8, for example, such as Figure 3 As shown, the present invention also includes a rubber pad 18 that contacts the inner side of the air inlet duct 2 and is fixed to the outer side of the filter frame 8 by screws.

[0039] When in use, when the filter frame 8 is placed inside the air inlet duct 2, the rubber pad 18 on the outside of the filter frame 8 is tightly connected to the inside of the air inlet duct 2, thereby improving the sealing between the air inlet duct 2 and the filter frame 8.

[0040] To improve the stability of air inlet 2, for example, such as Figure 1 As shown, the present invention also includes a fixing plate 27 for supporting the air inlet 2, which is bolted to the bottom of the air inlet 2.

[0041] During use, the fixing plate 27 installed at the bottom of the air inlet duct 2 supports the air inlet duct 2 and improves the stability of the air inlet duct 2.

[0042] For electrical equipment to function properly, for example, such as Figure 1 , Figure 2 and Figure 4 As shown, this utility model also includes the input terminals of motor B25, motor A4, air volume sensor 13, and controller 3, which are all electrically connected to the power supply terminal of an external power source.

[0043] When in use, the electrical equipment works normally by connecting to an external power source.

[0044] When this utility model is in use, when gas is to enter the Raymond machine body 1, the motor A4 outside the air inlet duct 2 is converted into mechanical energy by the controller 3. Then, the motor A4 drives the gear B15 outside the support rod 16 to rotate. Then, the gear B15 drives the drive rod 10 inside the gear A14 to rotate. Then, the drive rod 10 drives the external fan blade 9 to rotate, so that the external gas enters the air inlet duct 2. Then, the air volume sensor 13 inside the air inlet duct 2 transmits the air volume signal to the controller 3 outside the air inlet duct 2. Then, the controller 3 controls the speed of the motor A4, so as to facilitate the adjustment of the air volume entering the Raymond machine body 1.

[0045] When external gas enters the air inlet duct 2, the filter screens A17 and B19 in the filter frame 8 at the end of the air inlet duct 2 filter the impurities in the gas. Then, the fixing component 20 in the outer frame 5 releases the filter frame 8 from the air inlet duct 2. After cleaning the filter frame 8, the filter frame 8 is put back into the end of the air inlet duct 2. Then, the fixing component 20 in the outer frame 5 fixes the filter frame 8, which facilitates the disassembly and cleaning of the filter frame 8 in the air inlet duct 2.

[0046] When the filter frame 8 needs to be disassembled, the motor B25 at the bottom of the outer frame 5 converts the received electrical energy into mechanical energy under the action of the controller 3. The motor B25 drives the bidirectional lead screw 23 to rotate. Then, the reciprocating sleeves A21 and B24 outside the bidirectional lead screw 23 are both limited by the external structure. Then, the reciprocating sleeve A21 drives the limiting block A6 outside the transmission plate A22 to move, and the reciprocating sleeve B24 drives the limiting block B7 outside the transmission plate B26 to move, so that the limiting block A6 and the limiting block B7 are separated from the filter frame 8 respectively, thereby facilitating the removal of the filter frame 8 from the fixation.

[0047] Both motor A4 and motor B25 are servo motors, and a bearing is provided at the end of the bidirectional lead screw 23 away from motor B25;

[0048] When gear A14 drives drive rod 10 to rotate, drive rod 10 rotates in bushing 11 inside fixed rod 12, thereby improving the stability of drive rod 10 rotation. In addition, multiple through holes are opened on the surface of fixed rod 12 to allow gas to flow smoothly in air inlet duct 2.

[0049] When the filter frame 8 is placed into the air inlet duct 2, the rubber pad 18 on the outside of the filter frame 8 is tightly connected to the inside of the air inlet duct 2, thereby improving the sealing between the air inlet duct 2 and the filter frame 8.

[0050] The fixing plate 27 installed at the bottom of the air inlet duct 2 supports the air inlet duct 2 and improves the stability of the air inlet duct 2.
