Description

Technical Field

[0001] This utility model relates to the field of dust collection equipment technology, and more specifically, to a vacuum dust collection bin with a cylinder-driven door opening and unloading structure. Background Technology

[0002] Vacuum cleaning equipment is an indispensable tool, but traditional vacuum cleaners have many limitations in generating vacuum suction. Traditional dust collection bins primarily unload manually or using simple mechanical methods. Manual unloading is labor-intensive, inefficient, and exposes operators to harmful environments when handling materials containing hazardous substances. For dust collection bins with a certain negative pressure, traditional unloading structures face significant challenges. Due to the negative pressure within the bin, the unloading door requires overcoming considerable suction to open, making the unloading process extremely difficult. Material often adheres tightly to the unloading port due to the negative pressure, resulting in slow unloading speeds and even blockages. This necessitates stopping the machine for unloading, impacting production efficiency and increasing downtime and maintenance costs. Therefore, we propose a vacuum dust collection bin with a cylinder-operated door unloading structure. Utility Model Content

[0003] The purpose of this invention is to provide a vacuum dust collection bin with a cylinder-operated door unloading structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a vacuum dust collection bin with a cylinder-operated door unloading structure, comprising a main frame and a support frame. A dust collection bin is fixedly mounted on the top of the main frame; a unloading mechanism is fixedly mounted on the bottom of the dust collection bin; the unloading mechanism includes an unloading box connected in communication with the dust collection bin; a discharge port is opened on one side of the unloading box; a material gate is installed on the unloading box outside the discharge port; the lower end of the material gate is connected to the unloading box via two cylinders; a Roots pump and a motor are respectively mounted on the top of the support frame; a three-way butterfly valve is installed on the top of the Roots pump via a connecting pipe; the three-way butterfly valve is connected to the dust collection bin via a flexible hose.

[0005] Preferably, the connection between the material gate and the unloading box is a rotatable connection, with one end of the cylinder hinged to the fixed part of the unloading box and the other end hinged to the movable part of the material gate.

[0006] Preferably, the transmission connection between the motor and the Roots pump is a belt drive connection; the bottom end of the Roots pump is also provided with an exhaust silencer.

[0007] Preferably, the unloading box has a triangular cross-section and the discharge port is inclined.

[0008] Preferably, the main frame and the support frame are fixedly connected by welding, and the bottom ends of the main frame and the support frame are equipped with casters.

[0009] Beneficial effects: Compared with the prior art, the beneficial effects of this utility model are as follows: By using a cylinder to control the opening and closing of the material gate, precise unloading control can be achieved, as well as control of the unloading speed and unloading amount. Through the setting of the three-way butterfly valve, during the unloading stage, the negative pressure is released from the three-way valve by switching the channel of the three-way butterfly valve, so that the pressure in the dust collection bin can be quickly restored to a state of equilibrium with the outside, avoiding the problem that the material is difficult to discharge due to negative pressure during unloading, greatly improving the unloading speed. Moreover, the opening of the butterfly valve allows the dust collection bin to quickly depressurize and lose vacuum, which can achieve rapid vacuum loss without stopping the machine, and then open the material gate for unloading, improving the automation level and operation convenience of the equipment.

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example

[0017] Please refer to the accompanying drawings in the specification. In this embodiment of the utility model, a vacuum dust collection bin with a cylinder-operated door unloading structure includes a main frame 1 and a support frame 7 as the supporting frame of the overall structure. A dust collection bin 2 is fixedly installed at the top of the main frame 1, and a suction pipe for feeding is provided on one side of the dust collection bin. A unloading mechanism is fixedly installed at the bottom of the dust collection bin 2. The unloading mechanism includes an unloading box 3 that is connected to the dust collection bin 2. A discharge port 4 is opened on one side of the unloading box 3. A material gate 5 is installed on the unloading box 3 outside the discharge port 4. The lower end of the material gate 5 is connected to the unloading box 3 through two cylinders 6 to realize the opening and closing control of the unloading channel. A Roots pump 8 and a motor 12 are respectively installed at the top of the support frame 7. A three-way butterfly valve 10 is installed at the top of the Roots pump 8 through a connecting pipe 9. The three-way butterfly valve 10 is connected to the dust collection bin 2 through a flexible hose 11.

[0018] Furthermore, the connection between the material gate 5 and the unloading box 3 is a rotatable connection. One end of the cylinder 6 is hinged to the fixed part of the unloading box 3, and the other end is hinged to the movable part of the material gate 5, thereby precisely controlling the opening and closing angle and action process of the material gate 5, and realizing precise control of the unloading operation.

[0019] Furthermore, the transmission connection between the motor 12 and the Roots pump 8 is a belt drive connection; both the output end of the motor 12 and the output end of the Roots pump 8 are provided with pulleys, and belts are provided on the outside of the two pulleys. The bottom end of the Roots pump 8 is also provided with an exhaust silencer 13. The exhaust silencer 13 is provided with sound-absorbing material and an airflow buffer structure. The sound-absorbing material can effectively absorb high-frequency noise in the exhaust airflow, and the airflow buffer structure can reduce the flow rate and pressure fluctuation of the exhaust airflow, thereby synergistically reducing the exhaust noise to a range that meets the relevant environmental noise standards.

[0020] Furthermore, the unloading box 3 has a triangular cross-section and the discharge port 4 is inclined. The triangular structure of the unloading box 3 allows the material to converge towards the discharge port under the action of gravity during unloading, thus ensuring smooth unloading. In addition, its conical structure helps to reduce material residue and improve unloading efficiency.

[0021] Furthermore, the main frame 1 and the support frame 7 are fixedly connected by welding, and the bottom of the main frame 1 and the support frame 7 are equipped with casters 14. The casters 14 are universal casters with braking devices, which facilitate the flexible movement and positioning of the equipment in different ground environments. The braking device can effectively lock the casters 14 when the equipment is stationary to prevent the equipment from sliding accidentally.

[0022] Usage process:

[0023] During operation, the three-way butterfly valve 10 is first switched to the pressure relief channel during unloading. At this time, the negative pressure generated by the belt-driven Roots pump 8 and acting on the dust collection bin 2 is released from the three-way valve 10. As the negative pressure dissipates, the pressure inside the dust collection bin 2 gradually balances with the external environment. Simultaneously, the cylinder 6 is activated, its extension pushing the material gate 5 to rotate around the hinge point with the unloading box 3, thereby opening the discharge port 4. Since the dust collection bin 2 is no longer under negative pressure, the material can quickly and smoothly pass from the dust collection bin 2 through the unloading box 3 and out of the inclined discharge port 4 under the influence of gravity. By utilizing the negative pressure control function of the three-way butterfly valve and the mechanical opening linkage of the material gate, a rapid unloading process without negative pressure obstruction is efficiently achieved, improving unloading efficiency and ensuring the stability and reliability of equipment operation.

[0024] It is worth noting that the entire device is controlled via control buttons. Since the motor 12, Roots pump 8, and cylinder 6 matched to the control buttons are all common equipment and represent existing mature technology, their electrical connections and specific circuit structures will not be elaborated upon here. Power supply is also common knowledge in the field, and since this invention is primarily used to protect mechanical devices, the control method and circuit connections will not be explained in detail.

[0025] In the above process, through the design of this utility model, a cylinder is used to control the opening and closing of the material gate, which can achieve precise unloading control, as well as control the unloading speed and unloading amount. Through the setting of the three-way butterfly valve, during the unloading stage, by switching the channel of the three-way butterfly valve, the negative pressure is released from the three-way valve, so that the pressure in the dust collection bin is quickly restored to a state of equilibrium with the outside, avoiding the problem of material being difficult to discharge due to negative pressure during unloading, greatly improving the unloading speed. Moreover, the opening of the butterfly valve allows the dust collection bin to quickly depressurize and lose vacuum, which can be achieved by quickly losing vacuum without stopping the machine, and then opening the material gate for unloading, improving the automation level and operation convenience of the equipment. This application has a simple structure, strong practicality, and simple operation, and is worth promoting.
