Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, specifically a feeding device with a dust removal structure. Background Technology

[0002] A feeding mechanism is a mechanical device used to feed various materials into specific equipment or processes according to set requirements. It usually consists of a storage bin and a cover plate. The cover plate is opened during feeding and closed after feeding is completed. Feeding mechanisms are widely used in chemical, food, pharmaceutical, metallurgical, environmental protection and other industrial fields.

[0003] Existing feeding devices are usually limited in function. When feeding powdery materials, the sealing cover on the feeding port is open, which easily generates dust and pollutes the production site environment. After feeding, some powdery material will adhere to the inner wall of the storage silo and cannot be completely discharged, which easily leads to powder waste. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device with a dust removal structure, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A feeding device with a dust removal structure includes a feeding tank with a cover on top. A drive mechanism is provided on the outer wall of the feeding tank to drive the cover to swing open and close. A guide pipe is connected to the outer wall of the feeding tank near its top. A circular shell is fixedly connected to the end of the guide pipe. A suction pipe and an air guide pipe are respectively connected to the outer wall of the circular shell. A cylindrical core is tightly fitted and rotatably installed inside the circular shell. The cylindrical core has a connecting channel. The end of the air guide pipe is connected to a pulse tank fixed on the outer wall of the feeding tank. A linkage mechanism is provided on the side of the feeding tank to drive the cylindrical core to rotate and adjust when the drive mechanism is working, so as to switch the guide pipe between two modes: one connected only to the suction pipe and the other connected only to the air guide pipe.

[0007] Furthermore, the guide tube, circular shell, suction tube, and air guide tube are arranged in a T-shape, and the connecting channel is L-shaped, with the first port and the second port at each end. When the cover is completely closed, the first port is connected to the guide tube and the second port is connected to the air guide tube. When the cover is open at 90 degrees, the first port is connected to the suction tube and the second port is connected to the guide tube.

[0008] Furthermore, the drive mechanism includes a U-shaped seat, a shaft, and a drive motor. The U-shaped seat is fixed to the outer wall of the feeding tank, the shaft is rotatably mounted on the U-shaped seat, and an L-shaped swing arm is fixedly fitted on the shaft. The L-shaped swing arm is fixedly connected to the outer edge surface of the cover. The drive motor is fixed to the side of the U-shaped seat, and its output shaft is fixedly connected to one end of the shaft.

[0009] Furthermore, the linkage mechanism includes gear A, rack A, L-shaped connecting plate, rack B, and gear B. A rotating shaft is coaxially fixed at the bottom end of the cylindrical core. Gear A is fixedly mounted on the rotating shaft, gear B is fixedly mounted on the shaft, rack A is fixed on one end of the L-shaped connecting plate and meshes with gear A, and rack B is fixed on the other end of the L-shaped connecting plate and meshes with gear B.

[0010] Furthermore, a mounting base is fixed on the outer wall of the feeding tank, and at least two guide rods are fixed on the mounting base. The L-shaped connecting plate is provided with sliding holes, and each guide rod is slidably inserted into the corresponding sliding hole.

[0011] Furthermore, the guide pipe is arranged horizontally along the tangent direction of the feeding tank.

[0012] Furthermore, a sealing ring that presses against the cover is fixed on the top end face of the feeding tank.

[0013] Furthermore, an intercepting net is installed at the connection point between the guide pipe and the feeding tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0015] Through the cooperation of the drive mechanism and the linkage mechanism, the connection mode of the guide tube is switched synchronously during the opening and closing of the cover. When the cover is opened, the linkage cylindrical core rotates to connect the guide tube with the suction tube. By using the negative pressure suction of the external industrial vacuum cleaner, the dust scattered during feeding can be sucked up and collected through the guide tube and the suction tube, effectively avoiding dust pollution of the production environment and improving the environmental protection when feeding into the feeding tank.

[0016] When the cover is closed, the linkage cylindrical core rotates in the opposite direction, connecting the guide pipe and the air guide pipe. The pulse airflow from the pulse tank is blown tangentially into the feeding tank through the air guide pipe, connecting channel and guide pipe, so that the airflow forms a spiral downward flow field in the feeding tank, which can cover most of the inner wall of the feeding tank. This not only accelerates the discharge of materials, but also blows the powdery materials attached to the inner wall into the processing equipment, ensuring that the materials are discharged completely and reducing powder waste.

Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0026] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Example 1

[0027] Please see Figures 1-6 The present invention provides a feeding device with a dust removal structure, including a feeding tank 1 with a cover 2 on the top. The feeding tank 1 is installed on the top of the processing equipment 01, and the bottom of the feeding tank 1 is funnel-shaped with a larger top and a smaller bottom at the connection with the processing equipment 01. Powdered materials are fed into the feeding tank 1 and then fall into the processing equipment 01, realizing the feeding of powdered materials for subsequent processing. In addition, a feeding valve (not shown in the figure) is provided at the connection between the feeding tank 1 and the processing equipment 01 to control the feeding sequence.

[0028] The outer wall of the feeding tank 1 is provided with a drive mechanism 3 for driving the cover 2 to swing open and close. When it is necessary to add powdered material into the feeding tank 1, the cover 2 can be opened by swinging 90 degrees through the drive mechanism 3. After the powdered material is added, the cover 2 is rotated and reset to close by the drive mechanism 3, sealing the top of the cover 2.

[0029] A guide pipe 4 is connected to the outer wall of the feeding tank 1 near its top. A circular sleeve 5 is fixedly connected to the end of the guide pipe 4. A suction pipe 7 and an air guide pipe 8 are connected to the outer wall of the circular sleeve 5 respectively. The guide pipe 4, the circular sleeve 5, the suction pipe 7 and the air guide pipe 8 are arranged in a T-shape.

[0030] A cylindrical core 51 is tightly fitted and rotatably mounted inside the circular casing 5. The cylindrical core 51 has a connecting channel 52. A linkage mechanism 6 is provided on the side of the feeding tank 1. When the drive mechanism 3 is working, it drives the cylindrical core 51 to rotate and adjust. Then, when the cover 2 is opened and closed, it can be linked to the connecting channel 52 to adjust the direction, so as to switch the guide pipe 4 between two modes: one connected only to the suction pipe 7 and the other connected only to the air guide pipe 8.

[0031] Specifically, such as Figure 4 As shown, the connecting channel 52 is L-shaped, with the first port 521 and the second port 522 at its two ends. When the cover 2 is in the fully closed state, the first port 521 is connected to the guide tube 4, and the second port 522 is connected to the air guide tube 8. When the cover 2 is in the 90-degree open state, the first port 521 is connected to the suction tube 7, and the second port 522 is connected to the guide tube 4. That is, when the cover 2 is closed, the guide tube 4 is connected to the air guide tube 8, and when the cover 2 is open, the guide tube 4 is connected to the suction tube 7.

[0032] like Figure 4 As shown, the end of the air duct 8 is connected to the pulse tank 81 fixed on the outer wall of the feeding tank 1. In addition, the end of the suction pipe 7 is connected to an external industrial vacuum cleaner (not shown in the figure).

[0033] When the drive mechanism 3 drives the cover 2 to rotate 90 degrees to open so that powdery materials can be added into the feeding tank 1, the cylindrical core 51 is rotated and adjusted under the linkage of the linkage mechanism 6. At this time, the first port 521 is connected to the suction pipe 7 and the second port 522 is connected to the guide pipe 4. The negative pressure suction effect generated by the industrial vacuum cleaner can draw the small dust particles that are scattered around the top opening of the feeding tank 1 during feeding through the guide pipe 4 and the suction pipe 7 to the dust storage area in the industrial vacuum cleaner for storage, so as to avoid dust from being scattered and polluting the production site environment when the cover 2 is opened for feeding.

[0034] When the drive mechanism 3 drives the cover 2 to close, under the linkage of the linkage mechanism 6, the cylindrical core 51 is rotated and adjusted. At this time, the first port 521 is connected to the guide pipe 4, and the second port 522 is connected to the air guide pipe 8. At the same time, when the cover 2 is closed, it contacts the sensing plate (not shown in the figure) at the top of the feeding tank 1. The controller obtains the control signal and controls the valve body (not shown in the figure) on the pulse tank 81 to open (the specific control principle adopts the existing technology). The gas inside the pulse tank 81 enters the air guide pipe 8 and is blown into the feeding tank 1 through the connecting channel 52 and the guide pipe 4, forming a positive pressure. This can blow off the powdery material attached to the inner wall of the feeding tank 1, ensuring that the material in the feeding tank 1 is discharged. At the same time, the pulse positive pressure blowing can also accelerate the rapid discharge of the material in the feeding tank 1.

[0035] Among them, such as Figure 3 As shown, the guide pipe 4 is arranged horizontally along the tangent of the feeding tank 1. When the airflow is introduced into the feeding tank 1, the guide pipe 4 arranged along the tangent of the feeding tank 1 can make the airflow tangentially aligned with the inner wall of the feeding tank 1. Combined with the top of the feeding tank 1 being blocked by the cover 2, under the guidance of the inner wall of the feeding tank 1, a spiral downward airflow is formed, with a large coverage area, which improves the blowing effect on the material on the inner wall of the feeding tank 1.

[0036] In addition, such as Figure 2 As shown, a sealing ring 11 is fixed on the top end face of the feeding tank 1 and is squeezed into the cover 2. The sealing ring 11 is made of rubber. When the cover 2 is closed, it improves the sealing between the cover 2 and the feeding tank 1 and prevents material leakage when the feeding tank 1 is under positive pressure. Example 2

[0037] Please see Figure 3 The difference between this embodiment and Embodiment 1 is that:

[0038] An interception net 9 is installed at the connection point between the guide pipe 4 and the feeding tank 1. By setting the interception net 9, large particles of material can be intercepted, so as to avoid the large particles of material being accidentally sucked into the guide pipe 4 during negative pressure dust removal.

[0039] In addition, when the pulsed airflow enters the feeding tank 1, the airflow passes through the guide pipe 4 and can back-blow and clean the interception net 9 when it passes through the interception net 9, so as to back-blow the large particles of material that have penetrated into the holes of the interception net 9 back into the feeding tank 1, thereby achieving the anti-clogging and cleaning of the interception net 9. Example 3

[0040] Please see Figure 5 The difference between this embodiment and Embodiment 2 is that:

[0041] The drive mechanism 3 includes a U-shaped seat 31, a shaft 32, and a drive motor 33. The U-shaped seat 31 is fixed on the outer wall of the feeding tank 1. The shaft 32 is rotatably mounted on the U-shaped seat 31. An L-shaped swing arm 34 is fixedly fitted on the shaft 32. The L-shaped swing arm 34 is fixedly connected to the outer edge surface of the cover 2. The drive motor 33 is fixed on the side of the U-shaped seat 31, and its output shaft is fixedly connected to one end of the shaft 32.

[0042] When the drive motor 33 works, its output shaft can drive the shaft 32 to rotate. Under the fixed connection of the L-shaped swing arm 34, it can drive the drive mechanism 3 to swing synchronously, thereby providing effective drive for the swing opening and closing of the cover 2. Example 4

[0043] Please see Figure 5 The difference between this embodiment and Embodiment 3 is as follows:

[0044] The linkage mechanism 6 includes gear A62, rack A63, L-shaped connecting plate 64, rack B65, and gear B66. A rotating shaft 61 is coaxially fixed to the bottom end of the cylindrical core 51. Gear A62 is fixedly mounted on the rotating shaft 61, gear B66 is fixedly mounted on the shaft 32, rack A63 is fixed to one end of the L-shaped connecting plate 64 and meshes with gear A62, and rack B65 is fixed to the other end of the L-shaped connecting plate 64 and meshes with gear B66.

[0045] When the drive motor 33 drives the shaft 32 to rotate and open the cover 2, the shaft 32 drives the gear B66 to rotate. The rotating gear B66 meshes with the drive rack B65 and moves towards one side of the circular shell 5. Under the connection of the L-shaped connecting plate 64, the rack A63 moves synchronously. The rack A63 can mesh with the drive gear A62 and drive the rotating shaft 61 to rotate. The rotating shaft 61 drives the cylindrical core 51 to rotate inside the circular shell 5, thereby realizing the orientation adjustment of the connecting channel 52. When the cover 2 is opened at ninety degrees, the first port 521 is connected to the suction tube 7, and the second port 522 is connected to the guide tube 4.

[0046] When the drive motor 33 drives the shaft 32 to rotate and close the cover 2, similarly, through the linkage between the drive mechanism 3 and the linkage mechanism 6, the cylindrical core 51 can be driven to rotate in the opposite direction. When the cover 2 is completely closed, the first port 521 is connected to the guide pipe 4, and the second port 522 is connected to the linkage mechanism 6.

[0047] In addition, such as Figure 5 and Figure 6 As shown, a mounting base 67 is fixed on the outer wall of the feeding tank 1, and at least two guide rods 68 are fixed on the mounting base 67. The L-shaped connecting plate 64 is provided with sliding holes 641, and each guide rod 68 is slidably inserted into the corresponding sliding hole 641.

[0048] By sliding the guide rod 68 through the sliding hole 641 on the L-shaped connecting plate 64, the L-shaped connecting plate 64 is limited and slidably installed. This ensures the firmness of the L-shaped connecting plate 64 installation and provides a limiting and guiding effect for the L-shaped connecting plate 64, ensuring the smoothness and stability of the overall translation adjustment of the L-shaped connecting plate 64, rack A63 and rack B65.

[0049] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0050] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
