Description

Technical Field

[0001] This utility model relates to the field of dust collector unloading technology, and in particular to an energy-saving automatic quantitative unloading device for dust collectors. Background Technology

[0002] Pulse jet dust collectors are increasingly widely used. When a dust collector accumulates excessive dust, it uses pulse jet cleaning or backflushing to allow the dust and materials saturated on the filter bags or cartridges to fall into the ash hopper. When a certain volume is reached, the discharge port is opened to release the material. Currently, the market typically uses a rotary valve, metering sensors, and a control system for this purpose, resulting in high investment costs and high energy consumption. What is needed is a simple device with low investment costs, no energy consumption, and automatic quantitative unloading. Utility Model Content

[0003] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0004] Design an energy-saving automatic quantitative unloading device for a dust collector, including a housing, with a dust collector hopper located above the housing. The bottom surface of the hopper is inclined and extends into the housing and is fixedly connected to the inner wall of the housing. A rotating shaft is located on the highest end of the bottom of the hopper on the housing. One end of the rotating shaft extends out of the housing and is connected to a counterweight mechanism. The counterweight mechanism includes a force-bearing rod connected to one end of the rotating shaft. A discharge baffle that cooperates with the inclined surface of the bottom of the hopper is connected to the rotating shaft. A counterweight block is connected to the force-bearing rod through an adjustment mechanism. A locking mechanism is provided on the adjustment mechanism.

[0005] The adjusting mechanism includes an elongated hole on the force-bearing rod, with its front and rear ends communicating with the outside. Multiple evenly distributed slots are symmetrically arranged on the upper and lower inner walls of the elongated hole. A sleeve with open ends is provided inside the elongated hole, and a compression spring is provided inside the sleeve. Limiting plates are connected to both ends of the compression spring, and the two ends of the limiting plates are slidably connected to the inner wall of the sleeve. A locking rod that mates with a slot is connected to one side of each limiting plate. The end of the locking rod is spherical. A U-shaped movable sleeve is slidably fitted on the force-bearing rod. The sleeve is located inside the movable sleeve and is fixedly connected to the inner wall of the movable sleeve via a connecting post. The counterweight is connected to the bottom of the movable sleeve.

[0006] Preferably, the locking mechanism includes two fixed cylinders disposed on one side of the movable sleeve, a return spring, a stop plate, and a locking rod disposed in each fixed cylinder. The return spring is fitted onto the locking rod between the stop plate and the inner wall of the fixed cylinder. Multiple locking holes corresponding to the slots are respectively opened on the upper and lower end faces of the force-bearing rod. One end of the locking rod extends into the locking hole, and the other ends of the two locking rods extend out of the sleeve and are connected to the same pull plate.

[0007] Preferably, a sealing ring is embedded at the bottom end of the ash hopper.

[0008] Preferably, a flange is provided at the top of the shell, and a connecting flange that mates with the flange is fixedly fitted on the ash hopper, and the dust collector ash hopper and the shell are fixed together by the flange and the connecting flange.

[0009] Preferably, an interface flange is connected to the discharge port of the housing.

[0010] The beneficial effects of this utility model are as follows:

[0011] This utility model discloses an energy-saving automatic quantitative unloading device for dust collectors. A discharge baffle connected to a rotating shaft engages with the inclined surface at the bottom of the ash hopper. When the material in the ash hopper reaches a certain weight, the pressure it exerts on the discharge baffle overcomes the force of the counterweight mechanism, causing the discharge baffle to rotate around the rotating shaft, opening the bottom of the ash hopper and achieving automatic quantitative unloading. After the material is discharged, the counterweight mechanism resets the discharge baffle, stopping the unloading and successfully achieving quantitative unloading. The adjustment mechanism can adjust the position of the counterweight by moving the sleeve within the long hole of the force-bearing rod. Since the unloading volume requirements vary under different working conditions, changing the position of the counterweight changes the force of the counterweight mechanism on the rotating shaft, thereby adjusting the material weight required for the discharge baffle to open and meeting different quantitative unloading needs. Furthermore, the locking mechanism, through the coordinated operation of a return spring, a stop plate, a locking rod, and a pull plate, allows the locking rod to be inserted into the locking hole on the force-bearing rod after the adjustment mechanism has adjusted the counterweight position, further fixing the counterweight position. The pull plate allows operators to operate both locking rods simultaneously, facilitating the adjustment or fixing of the counterweight position and enhancing the operability and stability of the device.

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] Example 1

[0020] An energy-saving automatic quantitative unloading device for dust collectors, such as Figures 1 to 5 As shown, the device includes a housing 4, with a dust collector 1 and a dust hopper 7 located above the housing 4. The connection between the dust collector 1 and the dust hopper 7 is conical to facilitate material accumulation during discharge. The bottom surface of the dust hopper 7 is inclined and extends into the housing 4, where it is fixedly connected to the inner wall of the housing 4. A sealing ring is embedded at the bottom of the dust hopper 7. The sealing ring effectively prevents material leakage from the gap between the dust hopper 7 and the discharge baffle 5 during unloading, improving the sealing performance of the device, reducing material waste, and preventing pollution of the surrounding environment from material leakage. A flange 8 is located at the top of the housing 4, and a connecting flange 9 is fixedly fitted onto the dust hopper 7, which mates with the flange 8. The dust collector 1 and the housing 4 are fixed together through the flange 8 and the connecting flange 9. This connection method is not only convenient for installation and disassembly, facilitating maintenance and repair of the device, but also provides good sealing and connection strength, ensuring the stability and reliability of the connection between the ash hopper 7 and the shell 4.

[0021] An interface flange 6 is connected to the discharge port of the housing 4. The interface flange 6 is connected to the discharge port of the housing 4 to facilitate the connection of the unloading device with subsequent conveying or storage equipment.

[0022] A rotating shaft 24 is provided on the highest end of the bottom of the ash hopper 7 on the shell 4. One end of the rotating shaft 24 extends out of the shell 4 and is connected to a counterweight mechanism. The counterweight mechanism includes a force-bearing rod 2 connected to one end of the rotating shaft 24. A discharge baffle 5 that cooperates with the inclined surface of the bottom of the ash hopper 7 is connected to the rotating shaft 24. A counterweight block 3 is connected to the force-bearing rod 2 through an adjustment mechanism. A locking mechanism is provided on the adjustment mechanism. The discharge baffle 5 connected to the rotating shaft 24 cooperates with the inclined surface of the bottom of the ash hopper 7. When the material in the ash hopper 7 reaches a certain weight, the pressure generated by the material on the discharge baffle 5 overcomes the force of the counterweight mechanism, causing the discharge baffle 5 to rotate around the rotating shaft 24, opening the bottom of the ash hopper 7 and realizing automatic quantitative discharge. After the material is discharged, the counterweight mechanism resets the discharge baffle 5 and stops the discharge, thereby realizing quantitative discharge.

[0023] The adjustment mechanism includes an elongated hole 10 on the force-bearing rod 2, with its front and rear ends communicating with the outside. Multiple evenly distributed slots 15 are symmetrically arranged on the upper and lower inner walls of the elongated hole 10. A sleeve 17 with open ends is located inside the elongated hole 10, and a compression spring 23 is installed inside the sleeve 17. Limiting plates 22 are connected to both ends of the compression spring 23, and both ends of the limiting plates 22 are slidably connected to the inner walls of the sleeve 17. A locking rod 16, which mates with the slot 15, is connected to one side of each limiting plate 22. The end of the locking rod 16 is spherical, and a U-shaped movable sleeve 12 is slidably fitted onto the force-bearing rod 2. The sleeve 17 is located inside the movable sleeve 12 and is fixedly connected to the inner wall of the movable sleeve 12 via a connecting post 14. A counterweight 3 is connected to the bottom of the movable sleeve 12. The adjustment mechanism can adjust the position of the counterweight 3 by adjusting the position of the movable sleeve 17 within the elongated hole 10 of the force-bearing rod 2. Since the amount of material to be unloaded varies under different working conditions, the force exerted by the counterweight 3 on the rotating shaft 24 can be changed by altering the position of the counterweight block 3, thereby adjusting the material weight required for the unloading baffle 5 to open, in order to adapt to different quantitative unloading requirements.

[0024] The locking mechanism includes two fixed cylinders 21 located on one side of the movable sleeve 12, a return spring 20, a stop plate 19, and a locking rod 18 respectively located in each fixed cylinder 21. The return spring 20 is fitted onto the locking rod 18 between the stop plate 19 and the inner wall of the fixed cylinder 21. Multiple locking holes 11 corresponding to the slots 15 are respectively opened on the upper and lower end faces of the force-bearing rod 2. One end of the locking rod 18 extends into the locking hole 11, and the other ends of the two locking rods 18 extend out of the sleeve 17 and are connected to the same pull plate 13. Through the cooperation of the return spring 20, the stop plate 19, the locking rod 18, and the pull plate 13, the locking mechanism can, after the adjustment mechanism has adjusted the position of the counterweight 3, insert the locking rod 18 into the locking hole 11 on the force-bearing rod 2 to further fix the position of the counterweight 3. The pull plate 13 allows operators to simultaneously operate the two locking rods 18, allowing them to be pulled out or inserted into the locking hole 11, which facilitates the adjustment or fixing of the counterweight 3 and enhances the operability and stability of the device.

[0025] The working principle of this utility model is as follows: Dust collected by the dust collector 1 naturally accumulates through the conical structure of the ash hopper 7, and the weight of the material acts on the discharge baffle 5 at the inclined bottom. When the weight of the material exceeds the preset resistance of the counterweight mechanism, the discharge baffle 5 rotates around the rotating shaft 24, the bottom of the ash hopper 7 opens, and the material is discharged through the discharge port. After the material is discharged, the weight is reduced, and the counterweight 3 drives the rotating shaft 24 to rotate in the opposite direction through the force rod 2, the discharge baffle 5 resets and closes, and the discharge stops. When it is necessary to adjust the discharge amount, the locking mechanism is unlocked by the pull plate 13, and the sliding sleeve is used to adjust the position of the counterweight 3 on the long hole 10 of the force rod 2 (moving forward increases resistance / moving backward decreases resistance). The compression spring 23 drives the locking rod 16 to engage with the locking groove 15 and lock again, changing the critical weight for triggering discharge. After adjustment, release the pull plate 13. The locking rod 18 is reinserted into the locking hole 11 under the action of the return spring 20, thereby locking the position of the counterweight 3. During the unloading process, the sealing ring continuously prevents dust from leaking from the baffle gap, and the flange interface maintains the airtight connection between the equipment.
