Description

Technical Field

[0001] This utility model relates to the field of concrete batching technology, specifically to an environmentally friendly batching device for the production of concrete poles. Background Technology

[0002] The key material for pole production is concrete. Concrete is cement concrete, which is made by mixing cement as a binder, sand and stone as aggregates, and water in a certain proportion. Before being mixed with water, concrete is in powder form.

[0003] Utility model patent CN218875870U discloses a concrete batching device for environmentally friendly concrete production. This device includes a support frame and a batching hopper mounted on the support frame. A horizontally positioned fixed plate is located on the inner wall of the batching hopper, and a vertically rotatable shaft is connected to the fixed plate. A stirring blade is mounted on the rotating shaft, and a drive assembly for rotating the shaft is also provided on the batching hopper. By adopting the above technical solution, the rotating shaft drives the stirring blade to stir the sand at the outlet of the batching hopper, reducing the possibility of poor sand discharge and blockage. Compared to using a vibrator, the stirring blade can disperse the sand, preventing it from becoming increasingly compacted with vibration. This provides better anti-blocking performance, and the vibration is less, resulting in less damage to the batching hopper.

[0004] When the concrete batching device for environmentally friendly concrete production is used to collect materials after batching, a large amount of dust is generated during the process of discharging the batched concrete into the collection container because each component of the concrete is in powder form. This dust will drift around and pollute the surrounding environment, which does not meet the requirements of environmentally friendly production. In view of this, we propose an environmentally friendly batching device for concrete pole production. Utility Model Content

[0005] The purpose of this invention is to provide an environmentally friendly batching device for the production of concrete poles, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An environmentally friendly batching device for the production of concrete poles includes a batching hopper, the bottom of which is provided with a discharge channel, and a dust treatment device is installed on the batching hopper, the dust treatment device including a ring pipe and a treatment tank.

[0008] The ring tube is sleeved on the outside of the discharge channel. Several dispersing tubes are connected to the surface of the ring tube. Several through holes are opened on the surface of the dispersing tubes. A delivery tube is also connected to the ring tube. The end of the delivery tube passes through the processing tank and extends into the processing tank.

[0009] The processing tank is filled with water, the end of the delivery pipe is below the water surface, a top cover is installed on the top of the processing tank, a fan is installed on the top cover, a filter pipe is connected to the air inlet of the fan, the end of the filter pipe passes through the top cover and extends into the processing tank, and the end of the filter pipe is above the water surface.

[0010] A window is provided on the outer surface of the filter tube, and a cover is installed on the outer surface of the filter tube. The position of the cover corresponds to the position of the window. A pair of mesh plates are fixed on the inner wall of the cover, and a filter element is filled between the two mesh plates. When the cover is closed on the filter tube, the filter element extends into the interior of the filter tube.

[0011] Preferably, a fixing base for fixing the processing tank is provided on the outer side of the mixing hopper;

[0012] Preferably, the bottom of the processing tank is fixed with a plurality of support legs, and the bottom ends of the support legs are fixedly connected to the fixed base.

[0013] These two settings provide a stable mounting base for the treatment tank, enhancing its stability and preventing it from shaking during operation and affecting the dust treatment effect.

[0014] Preferably, the bottom surface of the annular tube is provided with a plurality of mounting protrusions, and the end of the dispersing tube is inserted into the mounting protrusion and threadedly connected to the mounting protrusion.

[0015] This feature facilitates the disassembly and maintenance of the dispersion tube, allowing for timely cleaning or replacement as needed.

[0016] Preferably, a plurality of the dispersion tubes are arranged in a ring at equal intervals on the ring tube, with the first end of the dispersion tube being away from the axis of the ring tube;

[0017] This setting increases the dust collection area of ​​the dispersion tube, enabling it to collect dust evenly and comprehensively, thus improving collection efficiency.

[0018] Preferably, a plurality of fixed support plates are provided between the annular pipe and the bottom of the batching hopper;

[0019] In this setup, the fixed support plate increases the connection stability between the ring pipe and the batching hopper, ensuring smooth dust conveying.

[0023] This setting facilitates the regular cleaning and disposal of the dust and waste residue that settles inside the tank, maintaining the normal operation of the device and its purification effect.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] 1. This environmentally friendly batching device for concrete pole production uses a fan to draw gas from the treatment tank through a filter pipe during operation, creating a negative pressure inside the tank. This causes the dust generated to be drawn in through a through hole in the dispersion pipe on the outside of the ring pipe. The dust then enters the ring pipe along with the airflow and then enters the treatment tank through the delivery pipe. The treatment tank is pre-filled with water, allowing the dust to be flushed into the water by the delivery pipe. Ultimately, most of the dust settles in the water, reducing dust pollution to the surrounding environment.

[0026] 2. The environmentally friendly batching device for concrete pole production uses a filter element installed on the filter pipe to filter out a small amount of dust that remains after sedimentation when the blower extracts air from the treatment tank, thus preventing the dust from escaping into the external environment.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0038] Please see Figures 1-7 An environmentally friendly batching device for concrete pole production includes a batching hopper 1 with a discharge channel 11 at its bottom. A dust treatment device 2 is mounted on the batching hopper 1, comprising a ring pipe 21 and a treatment tank 22. A fixing base 12 for securing the treatment tank 22 is located on the outer side of the batching hopper 1. Several support legs 225 are fixed to the bottom of the treatment tank 22, and the bottom ends of the support legs 225 are fixedly connected to the fixing base 12. The connection between the fixing base 12 and the support legs 225 stabilizes the treatment tank 22 and prevents it from shaking.

[0039] like Figure 2 , Figure 3 and Figure 4As shown, the annular pipe 21 is sleeved on the outside of the discharge channel 11. Several dispersing pipes 211 are connected to the surface of the annular pipe 21, and several mounting bosses 213 are provided on the bottom surface of the annular pipe 21. The ends of the dispersing pipes 211 are inserted into the mounting bosses 213 and threadedly connected to them. By sleeved on the outside of the discharge channel 11, the annular pipe 21, together with the dispersing pipes 211, forms a dust collection area around the discharge channel 11, increasing the dust collection effect. The threaded connection between the dispersing pipes 211 and the mounting bosses 213 facilitates disassembly and maintenance, allowing for timely cleaning or replacement of the dispersing pipes 211 as needed. Several through holes 2111 are provided on the surface of the dispersing pipes 211, and the dispersing pipes 211 are arranged in a ring at equal intervals on the annular pipe 21, with the first end of each dispersing pipe 211 away from the axis of the annular pipe 21. The through hole 2111 provides an entry channel for dust, and the annularly spaced dispersion tubes 211 can collect the dust generated during the discharge process evenly and comprehensively. The design of the head end being far away from the axis makes the overall dust absorption area wider and improves the collection efficiency.

[0040] like Figure 2 , Figure 3 and Figure 6 As shown, a delivery pipe 212 is also connected to the ring pipe 21. The end of the delivery pipe 212 passes through the processing tank 22 and extends into the processing tank 22, so that the delivery pipe 212 can transport the dust collected by the ring pipe 21 to the processing tank 22. Several fixed support plates 214 are provided between the ring pipe 21 and the bottom of the batching hopper 1. The fixed support plates 214 enhance the stability of the connection between the ring pipe 21 and the batching hopper 1, ensure the smooth dust conveying process, and avoid the connection from loosening due to shaking, which would affect the conveying effect.

[0041] like Figure 6 As shown, the treatment tank 22 is filled with water, and the end of the delivery pipe 212 is below the water surface. The top of the treatment tank 22 is equipped with a top cover 221, and a fan 222 is installed on the top cover 221. The air inlet of the fan 222 is connected to a filter pipe 223. The end of the filter pipe 223 passes through the top cover 221 and extends into the treatment tank 22. The end of the filter pipe 223 is above the water surface. When the fan 222 starts to work, the fan 222 discharges the air in the treatment tank 22 to the outside through the filter pipe 223, so that the treatment tank 22 is in a negative pressure state. This allows the dust to enter the water in sequence through the dispersion pipe 211, the ring pipe 21, and the delivery pipe 212. The water adsorbs and settles the dust, thus treating the dust and preventing dust pollution of the environment.

[0042] like Figure 7As shown, a window 2231 is provided on the outer surface of the filter tube 223, and a cover 2233 is installed on the outer surface of the filter tube 223. The position of the cover 2233 corresponds to the position of the window 2231. A pair of mesh plates 2235 are fixed on the inner wall of the cover 2233, and a filter element 2236 is filled between the two mesh plates 2235. When the cover 2233 is closed on the filter tube 223, the filter element 2236 extends into the interior of the filter tube 223. The combination of the window 2231, the cover 2233, the mesh plates 2235 and the filter element 2236 facilitates the installation, disassembly and replacement of the filter element 2236, ensuring that the filter tube 223 effectively intercepts residual dust in the gas for a long time. The left and right edges of the window 2231 are provided with first protruding edges 2232. The cover 2233 has an arc-shaped plate structure. The left and right edges of the cover 2233 are provided with second protruding edges 2234. The first protruding edges 2232 and the second protruding edges 2234 on the same side are fixedly connected by bolts. The bolt connection method makes the cover 2233 tightly connected to the filter tube 223, and the cover 2233 can be easily removed from the filter tube 223 by removing the bolts, so as to replace the filter element 2236.

[0043] like Figure 1 As shown, the bottom of the treatment tank 22 is connected to a slag discharge pipe 224, and a slag discharge valve 2241 is installed at the end of the slag discharge pipe 224. When it is necessary to clean the inside of the treatment tank 22, the mixture of sediment and water in the treatment tank 22 can be discharged out by opening the slag discharge valve 2241 to avoid excessive accumulation of sediment.

[0044] It is worth noting that the fan 222 involved in this utility model is existing conventional technology, and will not be described in detail here.

[0045] In this embodiment, the environmentally friendly batching device for concrete pole production first starts the blower 222. The blower 222 draws air out of the treatment tank 22 through the filter pipe 223, creating a negative pressure inside the treatment tank 22. Then, the through holes 2111 on the surface of the dispersion pipe 211 use the negative pressure to draw dust generated around the discharge channel 11 into the dispersion pipe 211. The dust is then transported to the treatment tank 22 through the ring pipe 21 and the delivery pipe 212 in sequence. Next, the dust enters the water with the airflow. The water adsorption effect causes the dust to settle to the bottom of the treatment tank 22, thus initially completing the dust purification. Finally, the blower 222 continuously draws out the water-washed gas from the treatment tank 22 through the filter pipe 223. The filter element 2236 inside the filter pipe 223 performs secondary filtration on the gas, intercepting residual dust and ensuring that the discharged gas is clean and meets the standards.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
