Description

Technical Field

[0001] The utility model relates to an activated carbon filling device, belonging to the technical field of solid material filling devices. Background Art

[0002] Among them, activated carbon filters are widely used in most refineries and chemical plants, mainly for removing colloidal substances, free chlorine, iron and other substances in water. After the activated carbon filter has been running for a period of time, the adsorption capacity of the activated carbon decreases, which will affect the water quality of the filter. Therefore, it is necessary to replace the activated carbon regularly to ensure the water quality of the filter. At present, most of the activated carbon filling in China is done manually, which is slow, takes a long time, has high labor intensity, high filling costs, and produces a lot of dust, which is harmful to human health.

[0003] In the prior art, a Chinese utility model patent with an authorization announcement number of CN207417766U and an authorization announcement date of May 29, 2018 discloses an activated carbon filling device for filling activated carbon into an adsorption system, comprising: a crane assembly capable of driving a packaging bag of activated carbon to a set position; a bag-breaking knife, the bag-breaking knife capable of piercing the bottom of the packaging bag, the bag-breaking knife capable of being installed above the feed hopper and the blade of the bag-breaking knife facing upward; the crane assembly comprises a track, a crane beam capable of moving along the track, a trolley capable of moving along the extension direction of the crane beam, a hook disposed on the trolley, and a driving member capable of driving the hook to rise and fall. The activated carbon filling device can effectively reduce the labor cost of filling activated carbon and improve the filling efficiency. However, when the activated carbon bag is broken and enters the device, a large amount of activated carbon dust will still be generated, polluting the environment and endangering human health.

[0017] The technical solution of the utility model is further described below in conjunction with specific implementation methods.

[0018] Example

[0019] The activated carbon filling device of this embodiment is as follows Figures 1 to 3 As shown, it includes a Venturi ejector and a spray device.

[0020] like Figures 1-2 As shown, the venturi ejector includes a mixing tube 1, a contraction tube 2, a diffusion tube 3 and a high-speed injection tube 4. The mixing tube 1, the contraction tube and the diffusion tube are arranged in sequence in the direction of material flow. The mixing tube 1 is provided with a negative pressure feed port 5, which is in the shape of an inverted cone, which is convenient for loading activated carbon; the high-speed injection tube 4 extends from the outside of the mixing tube 1 to the inside of the mixing tube 1, and one end of the high-speed injection tube 4 extending into the mixing tube 1 is a nozzle 6, which is arranged toward the contraction tube 2, and the other end of the high-speed injection tube 4 is a working fluid inlet 7, and the working fluid inlet 7 is provided with a bypass interface. Since the working fluid is water, the working fluid inlet 7 is a water inlet. In other embodiments, a water pressure regulating system can also be arranged before the working fluid inlet 7, so as to achieve the purpose of adjusting the loading speed of activated carbon.

[0021] like Figure 3 As shown, the spray device includes a water distribution coil 8 and a plurality of nozzles 9 arranged on the water distribution coil 8. One end of the water distribution coil 8 is opened as a water inlet, and the water inlet is connected to a bypass interface arranged on the working fluid inlet 7 through a bypass pipeline. A control valve is arranged on the bypass pipeline; the other end of the water distribution coil 8 is sealed. In some embodiments, the control valve on the bypass pipeline can be omitted. In other embodiments, the water inlet of the water distribution coil 8 can also be connected to other water sources.

[0022] The water distribution coil 8 is welded to the upper edge of the negative pressure feed port 5, and each nozzle is evenly arranged on the water distribution coil 8 and the nozzle of the nozzle faces the negative pressure feed port 5. In other embodiments of the activated carbon filling device, the nozzle on the water distribution coil 8 can also be omitted, and a slit can be directly opened at the position where the nozzle was originally set on the water distribution coil for spraying water. In other embodiments, the Venturi injector can also be replaced by other activated carbon filling devices. In other embodiments of the utility model, a bypass interface can be omitted on the working fluid inlet 7, and the water inlet of the water distribution coil 8 is connected to other water supply sources.

[0023] The activated carbon filling device of this embodiment is used for hydraulic filling of activated carbon, and the working process and principle are as follows: the activated carbon enters the Venturi ejector from the negative pressure feed port 5, the working fluid inlet 7 is connected to the high-pressure water source, the valve on the bypass pipe is opened, and the water enters the water distribution coil 8 from the water inlet of the water distribution coil 8 through the bypass pipe, and then is sprayed from each nozzle to the inside of the negative pressure feed port 5 to eliminate dust generated during the pouring of the activated carbon. The high-speed water flow enters the high-speed injection pipe from the working fluid inlet 7 and is sprayed into the mixing pipe from the nozzle of the high-speed injection pipe. In this process, the flow cross-section of the nozzle gradually becomes smaller, the water flow velocity gradually increases, the pressure potential energy of the water flow is gradually converted into kinetic energy, and the pressure gradually decreases. When the high-pressure water flow passes through the high-speed injection tube, most of the pressure potential energy is converted into kinetic energy, and the sprayed water flow forms a relative negative pressure in the mixing tube, which sucks the activated carbon entering the negative pressure feed port 7 into the mixer, thereby reducing the activated carbon particles suspended in the air to form dust when the negative pressure activated carbon is transferred from the packaging bag to the mixing tube. A small amount of activated carbon dust formed at the feed port falls into the mixing tube with the water sprayed by the spray device.

[0024] The activated carbon and high-speed water flow are fully mixed in the mixing tube and contraction tube of the Venturi ejector. The speed and energy of the two media are balanced, forming a stable fluid and then entering the diffuser. As the flow cross-sectional area gradually expands, the speed of the mixed fluid gradually decreases, the kinetic energy of the fluid gradually converts into potential energy, and the pressure gradually recovers. When it reaches the end of the diffuser, the pressure is fully restored, achieving the purpose of transporting activated carbon. During the mixing process of activated carbon and high-speed water flow, the protection of the water flow can prevent the activated carbon from wearing the device.

[0025] The activated carbon filling device of the utility model can greatly reduce the activated carbon dust entering the environment during the activated carbon filling, which is harmful to human health. The activated carbon filling device is flexible to use and can fill the activated carbon into the filter from any position. For example, a water hose can be connected from the sewage outlet of the catcher of the running activated carbon filter to increase the operating pressure of the outlet of the activated carbon filter by properly controlling the flow rate; or the water supply pressure of the purified water to the water treatment station can be increased; or a backwash water pump can be used to transport water, and the water outlet of the sewage outlet is transported to the working fluid inlet of the Venturi ejector. The outlet pipeline of the Venturi ejector is connected to the manhole of the activated carbon filter through a water hose, and the activated carbon can be loaded into the filter through hydraulic transportation.
