Description

Technical Field

[0001] This utility model relates to the field of dust control technology, specifically a dust control device. Background Technology

[0002] Water feeding is the first step in the water treatment process, affecting the effectiveness and efficiency of subsequent treatments. The feeding process mainly involves accurately and stably delivering the water source to be treated, such as river water, lake water, industrial wastewater, or domestic sewage, to the pretreatment unit of the water treatment system through equipment such as pumps and pipelines. During this process, it is necessary to strictly control the water quantity and quality parameters, adjust the delivery speed and pressure according to the characteristics of different water sources, and ensure that the feeding equipment operates normally, with regular maintenance and inspection to prevent problems such as leakage and blockage. This provides stable and suitable water quantity and quality conditions for subsequent treatment processes such as coagulation, sedimentation, filtration, and disinfection, ensuring the efficient operation of the entire water treatment system.

[0003] In existing technologies, common dust control methods include mechanical dust collection devices and closed conveyor feeding devices. Their disadvantages are low dust collection efficiency, requiring the fan to operate constantly, resulting in huge energy consumption; and limited dust collection effect, unable to effectively capture fine dust, and even requiring the maintenance of a vacuum environment. Their disadvantages are also extremely high cost, complicated maintenance, and complex cleaning when changing materials, which can easily lead to cross-contamination. Therefore, we need a dust control device. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are: In the scheme of this application: 1. To address the limited dust extraction efficiency during water treatment material feeding in existing technologies, this application employs a vacuum buffer tank to stabilize pressure fluctuations, buffer against accidental dust or liquid inhalation during settling, protect the vacuum pump, and rapidly establish negative pressure. Multiple valves are used to precisely control vacuum levels, gas flow, and flow rate, preventing improper feeding or material loss.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model embodiment provides a dust prevention device, such as Figure 1 , Figure 2and Figure 3 As shown, the system includes a feeding assembly 1, with a cleaning assembly 2 installed inside.

One end of the connecting pipe 102 is flanged and connected to a vacuum buffer tank 103. A pressure gauge 104 is fixedly connected to the outer wall of the vacuum buffer tank 103. A safety valve 105 is fixedly connected to the top of the vacuum buffer tank 103. One end of the vacuum buffer tank 103 is flanged and connected to a valve main pipeline 106. One end of the valve main pipeline 106 is equipped with an electro-pneumatic switching valve 107. A vacuum regulating valve 108 is installed on one side of the electro-pneumatic switching valve 107. A vacuum ball valve 109 is installed on one side of the vacuum regulating valve 108. A nitrogen purging valve 110 is installed on one side of the vacuum ball valve 109. A nitrogen purging valve 110 is installed on one side of the nitrogen purging valve 110. A dust filter 111 is installed, and a flange on one side of the dust filter 111 is connected to a reactor 112. A pressure sensor 113 is installed on the top of the reactor 112. First, the vacuum pump 101 is started to draw a vacuum, which is connected to the vacuum buffer tank 103 through the pipeline 102 to stabilize the pressure, buffer the settling of dust or liquid, protect the vacuum pump, and quickly reduce the negative pressure. The pressure gauge 104 adjusts the parameters. The safety valve 105 automatically opens to release gas when the pressure is over-pressured and closes when the pressure is normal. The main valve pipeline 106 connects the buffer tank and the vacuum port of the reactor 112. The electric switching valve 107 automatically switches the pipeline. The vacuum regulating valve 108 stabilizes the vacuum degree inside the reactor. The vacuum ball valve 109 controls the gas. The nitrogen purging valve 110 replaces the air and prevents oxidation and deterioration. The dust filter 111 prevents dust from entering the reactor. The material enters the reactor 112 to react. The pressure sensor 113 monitors the pressure and transmits the signal to the control system.

[0018] Further such as Figure 2 As shown, the vacuum pump 101 is connected to the vacuum buffer tank 103 via the connecting pipe 102. One end of the connecting pipe 102 is connected to the output end of the vacuum pump 101, and the other end of the connecting pipe 102 is connected to the air inlet of the vacuum buffer tank 103. The vacuum pump 101 can be started to continuously pump out gas to form a vacuum environment. The vacuum buffer tank 103 uses the deformation of the pre-filled gas inside to absorb the impact caused by the vacuum pump 101 pumping too fast or the system pressure fluctuation, preventing damage caused by unstable airflow.

[0019] Further such as Figure 3As shown, an electro-hydraulic switching valve 107, a vacuum regulating valve 108, a vacuum ball valve 109, a nitrogen purging valve 110, and a dust filter 111 are installed on the main valve pipeline 106.

A second bevel gear 210 is meshed with one side of the first bevel gear 209. A connecting rod 211 is fixedly connected to the inner wall of the second bevel gear 210. One end of connecting rod 211 is fixedly connected to... With the output shaft of motor 212, starting motor 212 causes connecting rod 211 to rotate, which in turn causes second bevel gear 210 to rotate, which in turn causes first bevel gear 209 to rotate, which in turn causes fixed rod 208 to rotate, which in turn causes connecting plate 206 to rotate, which in turn causes brush 203 to rotate, which in turn causes spur gear 204 to rotate. Simultaneously, spur gear 204 revolves around gear ring 205, allowing brush 203 to brush off the dust accumulated on filter element 202, thus cleaning filter element 202 and preventing dust from entering the pipeline during subsequent feeding.

[0021] Further such as Figure 5 As shown, the second bevel gear 210 forms a rotating structure with the first bevel gear 209 and the fixed rod 208. The inner wall of the first bevel gear 209 is connected to the outer wall of the fixed rod 208. The first bevel gear 209 and the second bevel gear 210 are arranged perpendicularly. The second bevel gear 210 can drive the first bevel gear 209 to rotate, which in turn drives the fixed rod 208 to rotate.

[0022] Further such as Figure 4 As shown, the spur gear 204 forms a rotating structure with the brush 203 through the gear ring 205, and the outer wall of the spur gear 204 meshes with the inner wall of the gear ring 205, and the inner wall of the spur gear 204 is connected to the outer wall of the brush 203. Through the spur gear 204, the spur gear 204 can rotate and revolve around the gear ring 205, driving the brush 203 to rotate.

[0023] Further such as Figure 5 As shown, the motor 212 forms a rotating structure with the second bevel gear 210 through the connecting rod 211. One end of the connecting rod 211 is connected to the output shaft of the motor 212, and the other end of the connecting rod 211 is connected to the inner wall of the second bevel gear 210. The motor 212 can drive the connecting rod 211 to rotate, which in turn drives the second bevel gear 210 to rotate.

[0024] Working Principle: During water treatment material feeding, vacuum pump 101 is first activated to create a vacuum, establishing a pressure difference between the internal and external atmospheric environments. This is connected to vacuum buffer tank 103 via connecting pipe 102. Vacuum buffer tank 103 stabilizes pressure fluctuations in the vacuum system, buffers and settles dust or liquids that may be accidentally sucked in, protects the downstream vacuum pump 101, provides a large instantaneous pumping volume, and quickly establishes the required negative pressure. System parameters are adjusted promptly based on pressure gauge 104 readings. A safety valve 105 automatically opens when the tank pressure unexpectedly exceeds a set threshold, releasing excess gas or liquid to prevent tank rupture due to overpressure. Once the pressure returns to normal, the valve automatically closes. To ensure safe system operation, the main valve pipeline 106 connects the vacuum buffer tank 103 to the vacuum ports of each reactor 112. Through the included electro-pneumatic switching valve 107, vacuum regulating valve 108, vacuum ball valve 109, nitrogen purging valve 110, and dust filter 111, the electro-pneumatic switching valve 107 receives signals from the control system and automatically switches the vacuum pipeline. The vacuum regulating valve 108 precisely controls and stabilizes the vacuum level inside the reactor at the set value, preventing excessive negative pressure from hindering material feeding or causing direct material removal. The vacuum ball valve 109 switches the gas path to control gas flow, and adjusts the ball angle to change the airflow size for flow control. This is achieved through a specific structure. The quantitative gas filling function allows the nitrogen purge valve 110 to purge and replace the air inside the reactor 112 before adding materials, preventing an explosion caused by the mixing of flammable gases such as hydrogen and oxygen. After adding materials, nitrogen is continuously introduced to form a protective layer, preventing the materials from oxidizing, deteriorating, or becoming damp, ensuring a stable reaction environment. Simultaneously, high-pressure nitrogen is used to remove residual impurities from pipes and inside the reactor, preventing valve blockage or affecting reaction efficiency. The dust filter 111 prevents dust from entering the reactor 112. Materials are added to the reactor 112 for reaction. The pressure sensor 113 monitors the pressure inside the reactor 112 in real time and transmits the signal to the PLC or DCS control system. After feeding is complete, the motor 212 is started. The motor 212 drives the connecting rod 211 to rotate, which in turn drives the second bevel gear 210 to rotate. The second bevel gear 210 then drives the first bevel gear 209 to rotate, which in turn drives the fixed rod 208 to rotate. The fixed rod 208 then drives the connecting plate 206 to rotate, which in turn drives the brush 203 to rotate. The brush 203 then drives the sprocket 204 to rotate. Simultaneously, the sprocket 204 revolves around the gear ring 205, allowing the brush 203 to brush off the dust accumulated on the filter element 202, thereby cleaning the filter element 202 and preventing dust from entering the pipeline during subsequent feeding.
