Description

Technical Field

[0001] The present application relates to the technical field of concrete admixture compounding equipment, and more specifically, to a concrete admixture compounding device. Background Art

[0002] Concrete admixtures refer to substances added to improve and adjust the properties of concrete.

[0003] Ensure that the amount of water added meets the concrete mix ratio requirements. After adding admixtures to the concrete in the mixing barrel, the flow meter is required to accurately measure the amount of water injected.

[0004] During the process of adding a quantitative amount of water to the mixing barrel using the above method, when the water injection volume reaches the preset value and the water valve is quickly closed, the water flow in the pipe will try to continue to flow forward due to inertia, but due to the obstruction of the valve, the water flow will quickly flow back. The alternation between this rapid backflow and forward flow will produce huge pressure fluctuations, namely the water hammer phenomenon. The strong vibration caused by the water hammer phenomenon can easily cause the bolts connecting the flow meter to loosen, which will cause leakage at the connection between the flow meter and the water pipe, thereby causing inaccurate amount of water added to the mixing barrel, affecting the quality of the concrete product.

[0005] In view of this, we propose a compounding device for concrete admixtures. Utility Model Content

[0009] The fastening structure includes a fastening screw and a locking ring arranged around the outer periphery of the fastening screw. The fastening screw is threadedly connected with a hexagonal screw sleeve, and the cross section of the hexagonal screw sleeve is a regular hexagon.

[0010] A plurality of limiting tooth grooves are evenly arranged on the inner ring wall of the locking ring, and an anti-loosening restraint component capable of cooperating with the limiting tooth grooves is arranged between the hexagonal screw sleeve and the locking ring inside the locking ring.

[0011] As an optional solution of the technical solution of this application document, the anti-loosening restraint member includes an arc-shaped holder;

[0014] An arc-shaped baffle is movably inserted in the arc-shaped slot, and both ends of the arc-shaped baffle are provided with end chamfered portions adapted to the limiting chamfered groove;

[0015] A vertical slot is provided on the side wall of the arc-shaped slot, and a telescopic card is slidably connected in the vertical slot. One end of the telescopic card is connected to a return spring, and the other end extends from the vertical slot and is provided with a convex tooth portion adapted to the limiting tooth groove.

[0016] As an optional solution to the technical solution of this application document, the outer diameter of the arc-shaped socket is the same as the inner diameter of the locking ring.

[0017] As an optional solution of the technical solution of this application document, one end of the return spring away from the telescopic clamp is connected to the end of the vertical slot.

[0018] As an optional solution to the technical solution of this application document, the locking ring is connected to the side wall of the first flange.

[0020] As an optional solution to the technical solution of this application document, a solenoid valve is also provided on the water injection pipe.

[0021] Beneficial effects: One or more technical solutions provided in the technical solutions of the present application have at least the following technical effects or advantages: 1. In the process of real-time monitoring of the amount of water added to the concrete mixer for mixing concrete and admixtures by the flowmeter in the flowmeter assembly, the present application can use the anti-loosening restraint part to carry out anti-loosening reinforcement treatment on the fastening structure for installing the flowmeter assembly, thereby effectively preventing the flowmeter assembly from loosening due to the water hammer effect during the process of measuring the amount of water injection, thereby causing inaccurate amount of water added to the mixing barrel, and ensuring the quality of the concrete product.

Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0032] Reference Figure 1 and Figure 2 The embodiment of the present application provides a compounding device for concrete admixtures, comprising a concrete mixer 1, a water injection nozzle 2, and a water diversion nozzle 3, wherein the opposite ends of the water injection nozzle 2 and the water diversion nozzle 3 are both connected to a second flange 5;

[0033] A flow meter assembly is provided between the two second flanges 5. The flow meter assembly includes a flow meter 6. The input end and the output end of the flow meter 6 are both connected to the first flange 4. Each first flange 4 is evenly provided with multiple fastening structures.

[0034] The fastening structure includes a fastening screw 7 and a locking ring 9 arranged around the outer periphery of the fastening screw 7. The locking ring 9 is connected to the side wall of the first flange 4. The side walls of the first flange 4 and the second flange 5 are provided with holes corresponding to the positions of each fastening structure for the studs on the fastening screw 7 to pass through.

[0035] A hexagonal screw sleeve 8 is threadedly connected to the fastening screw 7, and the cross section of the hexagonal screw sleeve 8 is a regular hexagon;

[0036] A plurality of limiting tooth grooves 10 are evenly formed on the inner ring wall of the locking ring 9, and an anti-loosening restraint member that can cooperate with the limiting tooth grooves 10 is provided inside the locking ring 9 between the hexagonal screw sleeve 8 and the locking ring 9;

[0037] The water injection nozzle 2 is also provided with a solenoid valve, which controls the pressure of the water flowing inside the water injection nozzle 2 and can also be used to open and close the pipeline.

[0038] In the present application, in the process of real-time monitoring of the amount of water added to the concrete mixer 1 for mixing concrete and admixtures by the flow meter 6 in the flow meter assembly, the fastening structure for mounting the flow meter assembly can be reinforced to prevent loosening by the anti-loosening restraint member, thereby effectively preventing the flow meter assembly from loosening due to the water hammer effect during the process of measuring the amount of water injected, thereby causing an inaccurate amount of water added to the mixing barrel, thereby ensuring the quality of the concrete product.

[0039] Reference Figures 2 to 4 , the embodiment of the present application provides a compounding device for concrete admixtures, wherein the anti-loosening restraint member includes an arc-shaped holder 11, and the outer diameter of the arc-shaped holder 11 is the same as the inner diameter of the locking ring 9;

[0040] The inner ring wall of the arc-shaped clamping seat 11 is provided with a clamping angle groove 15 adapted to the angle between any two adjacent side walls of the hexagonal screw sleeve 8;

[0041] An arc-shaped slot 18 is formed on the outer ring wall of the arc-shaped holder 11, and both ends of the arc-shaped slot 18 are provided with limiting chamfered grooves 20;

[0042] An arc-shaped baffle 17 is movably inserted into the arc-shaped slot 18. Both ends of the arc-shaped baffle 17 are provided with end chamfered portions 19 adapted to the limiting chamfered grooves 20. Due to the limiting effect of the limiting chamfered grooves 20 on the end chamfered portions 19, the arc-shaped baffle 17 is not only easily inserted into the arc-shaped slot 18, but also the arc-shaped baffle 17 inserted into the arc-shaped slot 18 will not be separated from the arc-shaped slot 18.

[0043] A vertical groove is provided on the side wall of the arc-shaped slot 18, and a telescopic card 13 is slidably connected in the vertical groove. One end of the telescopic card 13 is connected to a return spring 14, and the other end extends from the vertical groove and is provided with a convex tooth portion 12 adapted to the limiting tooth groove 10. The end of the return spring 14 away from the telescopic card 13 is connected to the end of the vertical groove.

[0044] Align the first flange 4 connected to the output end of the flowmeter 6 with the second flange 5 connected to the end of the water inlet pipe 3, and then align the first flange 4 connected to the output end of the flowmeter 6 with the second flange 5 connected to the end of the water injection pipe 2. Subsequently, pass the stud on the fastening screw 7 in the fastening structure through the holes on the first flange 4 and the second flange 5 and then through the locking ring 9. Then use a tool to thread the hexagonal screw sleeve 8 onto the stud of the fastening screw 7 and tighten it. After that, pull out the arc baffle 17 in the anti-loosening restraint from the arc slot 18 and then insert the arc socket 11 between the hexagonal screw sleeve 8 and the locking ring 9 and make the angle groove 15 stuck outside the angle formed by any two side walls of the hexagonal screw sleeve 8, so as to facilitate the staff to install the flowmeter assembly between the water injection pipe 2 and the water inlet pipe 3.

[0045] When the flowmeter 6 in the flowmeter assembly is performing real-time monitoring of the amount of water injected into the concrete mixer 1 for mixing concrete and admixtures, the hexagonal screw sleeve 8 becomes loose due to the water hammer effect, thereby causing the hexagonal screw sleeve 8 to drive the arc-shaped holder 11 in the anti-loosening restraint to rotate. When the convex tooth portion 12 is aligned with any limiting tooth groove 10 on the inner ring wall of the locking ring 9, under the elastic force of the return spring 14, the convex tooth portion 12 is quickly snapped into the corresponding limiting tooth groove 10, and the hexagonal screw sleeve 8 is restricted from further loosening, thereby realizing the anti-loosening reinforcement treatment of the fastening structure used to install the flowmeter assembly, and effectively preventing the flowmeter assembly from loosening due to the water hammer effect during the process of measuring the amount of water injected.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them.
