Description

Technical Field

[0001] This invention relates to the field of concrete additive equipment technology, and in particular to a concrete transport vehicle-mounted admixture storage and addition device. Background Technology

[0002] Concrete admixtures are chemical substances added during the concrete mixing process, accounting for less than 5% of the cement mass, that can significantly improve the performance of concrete. Concrete admixtures are characterized by a wide variety of types, small dosages, and a significant impact on concrete performance. They are characterized by low investment, quick results, and significant technical and economic benefits.

[0003] Concrete is generally transported using mixer trucks. Before transportation, concrete admixtures are added to the tank. During transportation, the mixer truck can mix the concrete and admixtures evenly. Currently, small-capacity portable plastic jugs or buckets are commonly used to store admixtures, which are added manually by climbing up to the rear feed inlet of the concrete truck. This poses a significant safety risk, and manual addition makes it difficult to accurately measure the amount of admixture, which is not conducive to the effective adjustment of the workability of the concrete. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a concrete transport vehicle-mounted admixture storage and addition device that eliminates the need for manual climbing to the rear of the concrete transport vehicle to add admixtures, accurately measures the amount of admixture added, and improves the effectiveness of adjusting the workability of concrete.

[0005] The present invention provides a concrete transport vehicle-mounted admixture storage and addition device, which adopts the following technical solution:

[0006] A concrete transport vehicle-mounted admixture storage and addition device includes an admixture storage tank installed on the transport vehicle and a conveying pipeline for adding admixtures from the admixture storage tank to the mixing tank of the transport vehicle. The conveying pipeline is equipped with a water pump for controlling the addition of admixtures, a flow meter for controlling the amount of admixtures added, and a control valve.

[0007] Furthermore, the control valve is provided in two parts and is respectively located on both sides of the delivery pipeline, on the flow meter and the control valve.

[0008] Furthermore, the water pump is an acid and alkali resistant pump.

[0009] Furthermore, the admixture storage tank is equipped with a cleaning tank, which is used to store cleaning fluid for cleaning the delivery pipeline. The cleaning tank is equipped with a cleaning pipeline connected to the delivery pipeline, and the cleaning pipeline is equipped with a switch valve for controlling the addition of cleaning fluid.

[0010] Furthermore, the end of the conveying pipeline near the mixing tank of the transport vehicle is provided with a drain pipe for discharging cleaning waste liquid, and the drain pipe is equipped with a drain valve.

[0011] Furthermore, the conveying pipeline is detachably equipped with a spray head for spraying the admixture into the mixing tank at one end of the pipeline located at the feeding port of the mixing tank of the transport vehicle.

[0012] Furthermore, a connecting pipe is provided between the admixture storage tank and the cleaning tank for transferring the cleaning liquid from the cleaning tank into the admixture storage tank, and a valve is provided on the connecting pipe for controlling the flow of the cleaning liquid.

[0013] Furthermore, the admixture storage tank is equipped with a cleaning assembly for cleaning and stirring. The cleaning assembly includes a stirring paddle disposed in the admixture storage tank and a drive component for driving the stirring paddle to rotate.

[0014] Furthermore, the admixture storage tank is provided with a feeding port on one side for adding admixtures and cleaning fluid.

[0015] Furthermore, the admixture storage tanks are provided in two symmetrically arranged on both sides of the mixing tank of the transport vehicle.

[0016] In summary, the present invention has at least one of the following beneficial effects: it eliminates the need for manual climbing to the rear of the concrete transport truck to add admixtures, avoiding the safety risk of personnel falling from heights; and it is equipped with a flow meter to accurately measure the added admixtures, thereby improving the effectiveness of secondary adjustment of concrete workability.

[0021] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0022] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0023] This invention discloses an onboard storage and addition device for admixtures in concrete transport vehicles. (Refer to...) Figure 1 The concrete transport vehicle admixture storage and addition device includes an admixture storage tank 1 installed on the transport vehicle and a conveying pipe 2 for adding the admixture from the storage tank 1 to the mixing tank of the transport vehicle. The conveying pipe 2 extends along the edge of the transport vehicle to the rear of the vehicle and then bends upward to the inlet of the mixing tank. The conveying pipe 2 is equipped with a water pump 21 for controlling the addition of admixtures, a flow meter 22 for controlling the amount of admixture added, and a control valve 23. In this embodiment, the water pump 21 is an acid and alkali resistant pump to avoid corrosion of the water pump 21 by acid and alkali solutions. Two control valves 23 are provided and are respectively installed on both sides of the conveying pipe 2, located on the flow meter 22 and the control valve 23. By inputting the value of the amount of admixture to be added into the flow meter, the amount of admixture added to the concrete can be controlled, making the addition of admixtures more accurate.

[0024] Reference Figure 1 In order to make it easier for the admixture to mix with the concrete, the delivery pipe 2 is detachably installed with a spray head 26 at one end of the feed port of the mixing tank of the transport vehicle for spraying the admixture into the mixing tank. The spray head 26 faces the inside of the mixing tank of the transport vehicle, and the admixture can be directly sprayed into the mixing tank through the spray head 26, so that it can have more sufficient contact with the concrete in the mixing tank.

[0025] Reference Figure 1 The admixture storage tank 1 is equipped with a cleaning tank 3, which is used to store the cleaning liquid for cleaning the delivery pipeline 2. In this embodiment, the cleaning liquid is water. The cleaning tank 3 is equipped with a cleaning pipeline 31 that is connected to the delivery pipeline 2. The cleaning pipeline 31 is equipped with a switch valve 32 for controlling the addition of cleaning liquid. When the admixture storage tank has not been used for a long time or has been used up, it is necessary to clean the delivery pipeline 2. The cleaning liquid in the cleaning tank 3 can be delivered to the delivery pipeline 2 through the switch valve 32. The water pump 21 can make the cleaning liquid clean the delivery pipeline 2, so as to avoid excessive admixture residue in the delivery pipeline 2 from affecting subsequent use.

[0026] Reference Figure 1 The conveying pipe 2 is equipped with a drain pipe 24 for discharging cleaning waste liquid at one end near the mixing tank of the transport vehicle. The drain pipe 24 is located at the upward bend of the conveying pipe 2 and extends downward. The drain pipe 24 is equipped with a drain valve 25. When cleaning the conveying pipe 2, the two control valves 23 on the conveying pipe 2 are closed, and the switch valve 32 and the drain valve 25 are opened, so that the waste cleaning liquid that has cleaned the conveying pipe 2 can be discharged from the drain pipe 24, which can prevent the waste cleaning liquid from being directly discharged into the mixing tank of the transport vehicle.

[0027] Reference Figure 1Meanwhile, to facilitate the cleaning of the admixture storage tank 1, a connecting pipe 4 is provided between the admixture storage tank 1 and the cleaning tank 3 for putting the cleaning liquid in the cleaning tank 3 into the admixture storage tank 1. The connecting pipe 4 is equipped with a valve 41 for controlling the flow of the cleaning liquid. By opening the valve 41, the cleaning liquid in the cleaning tank 3 can enter the admixture storage tank 1 to clean the admixture storage tank 1. The cleaning liquid after cleaning is discharged into the drain pipe 24 through the conveying pipe 2, and the waste liquid is discharged through the drain pipe 24. At the same time, the conveying pipe 2 can also be cleaned again.

[0028] Reference Figure 1 and Figure 2 To improve the cleaning effect of the admixture storage tank 1, a cleaning assembly 5 for cleaning and stirring is provided inside the admixture storage tank 1. The cleaning assembly 5 includes a stirring paddle 51 disposed inside the admixture storage tank 1 and a drive component 52 for driving the stirring paddle 51 to rotate. In this embodiment, the drive component 52 is a motor. The drive component 52 is installed in the middle position of the top of the admixture storage tank 1. The middle position of the cleaning box 3 on the top of the admixture storage tank 1 is recessed inward to provide space for the installation of the drive component 52. The stirring paddle 51 is vertically installed at the output end of the motor and is located inside the admixture storage tank 1. When cleaning the admixture storage tank 1, the cleaning liquid is stirred by the stirring paddle 51, which can improve the cleaning effect of the admixture storage tank 1.

[0029] Reference Figure 1 In order to facilitate the addition of admixtures or cleaning fluids into the admixture storage tank 1, a feeding port 11 for adding admixtures and cleaning fluids is provided on one side of the admixture storage tank 1.

[0030] In this embodiment, two admixture storage tanks 1 are installed on the same concrete transport truck, respectively located on both sides of the mixing tank. The two admixture storage tanks 1 can be configured with two kinds of admixtures. Both admixture storage tanks 1 are equipped with a cleaning box 3, and the two admixture storage tanks 1 share a water pump 21, which makes it more convenient to use and reduces costs.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
