Description

Technical Field

[0001] This invention relates to the field of cement mixing, and more particularly to a cement reinforcing agent spraying device. Background Technology

[0002] Cement reinforcing agent is a powdered admixture added to cement to improve its strength and performance. In actual use, the powdered cement reinforcing agent is usually mixed with water in a certain proportion to form a liquid, and then sprayed into the cement mixer through a special spraying equipment to give full play to the strength-enhancing effect of the reinforcing agent.

[0003] However, since cement reinforcing agents are fine-particle, low-density powdery materials, they are easily scattered and dusty during the pouring process into the mixing drum, resulting in waste of cement reinforcing agents, pollution of the working environment, and harm to the respiratory health of operators. Although some existing equipment uses water mist spraying to suppress dust, the water mist spraying range is limited, and the water mist barrier is difficult to cover the entire feed inlet area of ​​the mixing drum. Dust can easily spread from areas not covered by water mist into the surrounding air, and the dust suppression effect is not ideal. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the existing technology. The present invention proposes a cement reinforcing agent spraying device.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a cement reinforcing agent spraying device, comprising: a lower support, a mixing tank disposed on the surface of the lower support for holding materials, a discharge hole disposed at the bottom of the mixing tank for discharging materials, and a water supply pipe connected to the discharge hole for spraying. It also includes a lower support frame installed on the outside of the mixing tank for support. The lower support frame has a water tank for water supply inside. A water pumping pipe is connected to the surface of the water tank for pumping water. One end of the water pumping pipe is connected to a water pump for power. The outlet of the water pump is connected to a water supply pipe. One end of the water supply pipe is connected to a water spraying pipe installed on the outside of the mixing tank. The water spraying pipe has a spray nozzle inside for spraying water. The water spraying pipe is arranged in a ring on the surface of the mixing tank. When the water pump is started, the water in the water tank is introduced into the water spraying pipe through the water pumping pipe and the water supply pipe. The water is sprayed into the inside of the mixing tank from the spray nozzle on the surface of the spraying pipe. The water sprayed from the spraying pipe gathers in the middle of the mixing tank, reducing the dust generated when the reinforcing agent is poured into the mixing tank.

[0006] Preferably, the surface of the mixing tank is provided with a dust-blocking ring for blocking dust, and the surface of the dust-blocking ring is provided with an arc groove for pouring the reinforcing agent, the arc groove having a D-shaped opening.

[0007] Preferably, the edge of the arc groove is provided with a bent plate that is inclined downward relative to the dust-blocking ring, and the bottom of the dust-blocking ring is provided with a lower ring that fits into the inside of the mixing tank, so that the dust-blocking ring can rotate inside the mixing tank. When the reinforcing agent is poured into the arc groove, the bent plate further blocks the dust.

[0008] Preferably, the lower end of the dust baffle ring is connected to a connecting rod, and the surface of the connecting rod is provided with a lower plate located at the center of the mixing tank. The surface of the lower plate is provided with a connecting cone for splashing the water sprayed from the nozzle.

[0009] Preferably, the connecting cone is a multi-faceted pyramid, so that when the water flow impacts the plane of the connecting cone, the water flow splashes in a circular pattern, thus blocking the dust.

[0010] Preferably, the bottom of the mixing tank is equipped with a motor as the stirring power source, and the inside of the mixing tank is equipped with stirring blades for stirring. The stirring blades are connected to the motor drive shaft, and the motor drives the stirring blades to stir the reinforcing agent and water inside the mixing tank.

[0011] Preferably, the motor drive shaft is located in the middle of the stirring blade, and the stirring blade is provided with a circular groove and an oblong groove on both sides of the drive shaft. The circular groove and the oblong groove are different in size and shape. When the stirring blade rotates, the reinforcing agent passing through the circular groove comes into contact with the oblong groove of different size and shape, thereby increasing the oscillation amplitude of the reinforcing agent.

[0012] Preferably, the upper end of the lower support is provided with an upper water tank, and the connection position between the upper water tank and the lower water tank is provided with a through groove for communication. The surface of the upper water tank is provided with a rotatable flip cover for filling. Water is poured into the upper water tank by rotating the flip cover, and the water enters the lower water tank through the through groove.

[0013] Preferably, the surface of the lower support is provided with a side support for supporting the water delivery pipe, the surface of the water delivery pipe is provided with an adjustable tube with an adjustable angle, and one end of the adjustable tube is provided with a nozzle for dispensing the reinforcing agent.

[0014] Preferably, the surface of the mixing tank is provided with a rotatable top cover, the surface of the top cover is provided with an upper fastener, and the surface of the mixing tank is provided with a lower fastener for fixing the upper fastener. The lower fastener locks the upper fastener and fixes the top cover to the surface of the mixing tank.

[0015] Compared with the prior art, the beneficial effects of the present invention include: by connecting a water spray pipe to the upper outer periphery of the mixing tank, the water spray pipe has multiple spray nozzles for water spraying inside, and the spray nozzles are evenly distributed in the annular direction; water is sprayed into the interior of the mixing tank from each spray nozzle, part of the water flow converges in the middle of the mixing tank to form a first layer of water mist barrier, and another part of the water flow impacts multiple inclined planes of the connecting cone, is reflected and splashed into a circular water curtain to form a second layer of water mist barrier. The double water curtain barrier covers the area of ​​the mixing tank inlet, effectively blocking and adsorbing the dust generated during the pouring process. At the same time, when the cement reinforcing agent is poured into the arc groove, the dust baffle ring and the bending plate block the dust that spreads upward during the pouring process, making it difficult for the dust to overflow from the arc groove; the operator can also rotate the dust baffle ring as needed to adjust the arc groove to a suitable position for convenient pouring.

[0023] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0025] This invention provides a cement reinforcing agent spraying device, such as... Figure 1 As shown, the lower support 5 serves as the overall support foundation. The lower support 5 has a square box structure. Four casters are fixed to the four corners of the bottom of the lower support 5 with bolts, so that the entire device can move flexibly in the work area. The lower support 5 has a water tank 6 fixedly connected inside for water supply. The water tank 6 occupies the two side cavities inside the lower support 5 and is used to store water for dust suppression.

[0026] like Figure 1 As shown, the mixing tank 3 has a cylindrical structure. The lower end of the mixing tank 3 is fixedly connected to the upper surface of the lower support 5 by bolts. The mixing tank 3 is used to hold cement reinforcing agent materials. The bottom of the mixing tank 3 has a discharge hole 27 for discharging materials, and the discharge hole 27 is connected to the water supply pipe 9.

[0027] A side support 10 is welded to the side of the lower support 5. The side support 10 is a vertical plate structure located on one side of the mixing tank 3. One end of the water supply pipe 9 is connected to the discharge hole 27 at the bottom of the mixing tank 3 via a power pump. The middle part of the water supply pipe 9 is located inside the side support 10, providing stable support for the water supply pipe 9. The other end of the water supply pipe 9 is connected to an adjustable pipe 8 via a universal joint. The other end of the adjustable pipe 8 is threaded to a nozzle 7 for discharging the reinforcing agent. The operator can change the spray direction of the nozzle 7 by adjusting the angle of the adjustable pipe 8 according to the spray position requirements.

[0028] The top of the mixing tank 3 is connected to a rotatable top cover 1 via a hinge. The top cover 1 is used to seal the mixing tank 3 during the mixing process. An upper fastener 28 is welded and fixed to the surface of the top cover 1. A lower fastener 29 for fixing the upper fastener 28 is welded and fixed to the outer surface of the mixing tank 3. The upper fastener 28 is locked by the lower fastener 29, thereby fixing the top cover 1 to the surface of the mixing tank 3, ensuring the stable sealing of the top cover 1 during the mixing process, and preventing dust and water mist from overflowing.

[0029] like Figure 2 As shown, one end of the pump pipe 11 extends into the lower water tank 6, and the other end of the pump pipe 11 is connected to the inlet of the water pump 13 via a flange. The water pump 13 serves as the power source for water supply in this device. The water pump 13 is bolted to the upper end of the upper water tank 12. The outlet of the water pump 13 is connected to the water supply pipe 14 via a flange. The other end of the water supply pipe 14 is connected to the spray pipe 15 located outside the mixing tank 3 via a flange. The spray pipe 15 has a ring structure and is fixedly connected to the upper outer periphery of the mixing tank 3 by clamps. It is arranged in a ring around the mixing tank. The surface of the mixing drum 3; the interior of the water spray pipe 15 is machined with multiple spray pipes for spraying water. The multiple spray pipes are evenly distributed along the annular direction of the water spray pipe 15, and the nozzles of the spray pipes face the interior of the mixing drum 3. When the water pump 13 is started, the water in the lower water tank 6 is drawn out through the water pumping pipe 11 and introduced into the water spray pipe 15 through the water supply pipe 14. The water is sprayed into the interior of the mixing drum 3 from the spray pipes of the water spray pipe 15. The water sprayed from the multiple spray pipes converges in the middle of the mixing drum 3 to form a water mist barrier, which effectively reduces the dust generated when the cement reinforcing agent is poured into the mixing drum 3.

[0030] like Figure 3 As shown, the upper end of the lower support 5 is fixedly connected to the upper water tank 12 by welding. The connection position between the upper water tank 12 and the lower water tank 6 is machined with a through groove 17 for connecting the internal spaces of the two, so that the upper water tank 12 and the lower water tank 6 are interconnected. The surface of the upper water tank 12 is rotatably connected to a hinged cover 4 for filling with water. By rotating the cover 4, water can be poured into the interior of the upper water tank 12. The water flows naturally into the interior of the lower water tank 6 through the through groove 17, thereby replenishing the water used for dust suppression.

[0031] like Figure 6 As shown, a motor 16, which serves as the stirring power source, is fixedly connected to the bottom of the mixing tank 3 by bolts. The power shaft of the motor 16 extends upward into the interior of the mixing tank 3. The interior of the mixing tank 3 is equipped with a stirring blade 24 for stirring. The middle position of the stirring blade 24 is fixedly connected to the power shaft of the motor 16. After the motor 16 is started, it drives the stirring blade 24 to rotate inside the mixing tank 3, stirring and mixing the cement reinforcing agent and water inside the mixing tank 3.

[0032] Furthermore, the power shaft of the motor 16 is inserted into the middle of the stirring blade 24. The stirring blade 24 has multiple circular grooves 25 on one side of the power shaft and multiple elongated grooves 26 on the other side of the power shaft. The circular grooves 25 have circular openings, and the elongated grooves 26 have elongated elliptical openings. The circular grooves 25 and the elongated grooves 26 are different in size and shape. When the stirring blade 24 rotates, the cement reinforcing agent passing through the circular grooves 25 then comes into contact with the elongated grooves 26 of different sizes and shapes. Due to the different groove shapes on both sides, the cement reinforcing agent experiences different resistance and vibration frequencies on both sides, thereby increasing the oscillation amplitude of the cement reinforcing agent during the stirring process and improving the uniformity of the stirring.

[0033] like Figure 4 and Figure 5 As shown, a dust baffle ring 2 for blocking dust is installed at the upper part of the interior of the mixing tank 3. The bottom of the dust baffle ring 2 is fixedly connected to a lower ring 23 that fits against the inner wall of the mixing tank 3 by welding. The lower ring 23 slides against the inner wall of the mixing tank 3, allowing the dust baffle ring 2 to rotate inside the mixing tank 3. The surface of the dust baffle ring 2 is machined with an arc groove 18 for pouring cement reinforcing agent. The arc groove 18 has a D-shaped opening, that is, one side of the arc groove 18 is straight and the other side is arc-shaped. The operator can pour the cement reinforcing agent into the mixing tank 3 through the arc groove 18.

[0034] Furthermore, the edge of the arc groove 18 is fixedly connected by welding to a bent plate 20 that is inclined downward relative to the dust baffle ring 2. The plate surface of the bent plate 20 is arranged to be inclined downward relative to the horizontal surface where the dust baffle ring 2 is located. When cement reinforcing agent is poured into the arc groove 18, the bent plate 20 further blocks the dust that spreads upward during the pouring process, making it difficult for dust to overflow from the arc groove 18.

[0035] A connecting rod 19 is welded to the lower end of the dust baffle ring 2. The connecting rod 19 has an L-shaped structure. One end of the connecting rod 19 is fixedly connected to the lower end of the dust baffle ring 2, and the other end of the connecting rod 19 extends toward the center of the mixing tank 3. A lower plate 21 located at the center of the mixing tank 3 is welded to the end of the connecting rod 19. The lower plate 21 has a circular plate structure. A connecting cone 22 that splashes water sprayed from the spray pipe is welded to the upper surface of the lower plate 21. The connecting cone 22 has a multi-faceted pyramid structure with multiple mutually inclined planes. When the water sprayed from the spray pipe 15 impacts the plane of the connecting cone 22, the water is reflected and dispersed by the multiple planes of the multi-faceted pyramid, splashing in a circular pattern in all directions, forming a larger water curtain barrier above the interior of the mixing tank 3, effectively blocking the dust generated during the dumping process.

[0036] In this embodiment, the water pump 13 is started, and the water pump 13 draws water from the lower water tank 6 through the water suction pipe 11 and introduces it into the water spray pipe 15 located outside the mixing tank 3 through the water supply pipe 14. The water is sprayed into the interior of the mixing tank 3 from the spray pipe inside the water spray pipe 15. Part of the water gathers in the middle of the mixing tank 3, and the other part of the water impacts the polygonal pyramidal plane of the connecting cone 22 on the lower plate 21, is reflected and splashed into a circular water curtain. The operator pours the cement reinforcing agent into the interior of the mixing tank 3 through the arc groove 18 on the dust baffle ring 2. The bent plate 20 at the edge of the arc groove 18 shields the dust generated during the pouring process. The water curtain sprayed from the spray pipe and the circular water curtain formed by the reflection of the connecting cone 22 together block and adsorb the dust, effectively reducing the dust generated during the pouring process. After the dust is dispersed and the contents are poured out, the top cover 1 is rotated to seal the top of the mixing drum 3. The top cover 1 is then locked in place by the lower fastener 29 and the upper fastener 28. The motor 16 drives the mixing blade 24 to rotate inside the mixing drum 3, mixing the cement reinforcing agent and water. During the mixing process, the cement reinforcing agent passes through the circular groove 25 on one side of the mixing blade 24 and then comes into contact with the elongated circular groove 26 on the other side, which is different in size and shape, thus generating oscillations at different frequencies, making the mixing more uniform. After the mixing is completed, the cement reinforcing agent mixture flows out from the discharge hole 27 at the bottom of the mixing drum 3 and is transported by the power pump connected to the surface of the water supply pipe 9. The spraying angle is adjusted by the regulating pipe 8, and finally sprayed from the nozzle 7 into the interior of the cement mixer to complete the spraying operation.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
