Description

Technical Field

[0001] This utility model relates to the field of concrete processing technology, specifically to a concrete accelerator delivery device. Background Technology

[0002] Accelerators are admixtures added to concrete to enable it to set and harden rapidly. They are mainly classified as inorganic salts and organic compounds. As powdered solids, their dosage is only 2%–3% of the cement content in concrete, yet they can cause the concrete to initially set within 5 minutes, while the accelerator itself sets within 12 minutes. This achieves the purpose of rapid setting of concrete in emergency repairs or tunnels. They are indispensable additives in shotcrete construction. Their function is to accelerate the hydration and hardening of cement, forming sufficient strength in a very short time to meet the requirements of special construction methods.

[0003] Patent document CN209023693U discloses a conveying device for concrete accelerators. This conveying device, through the cooperation of the above-mentioned structure, uses a sliding plate to control the falling of the concrete accelerator, which then falls onto a weighing platform for weighing. Finally, a first motor indirectly drives the platform to rotate to the right, automatically delivering the concrete accelerator onto the conveying device for transport. This reduces the labor intensity of manual labor and effectively improves work efficiency.

[0004] However, the conveying device used for concrete accelerators has the following disadvantages: during the conveying process on the conveyor belt, the concrete accelerator is easily exposed to air and moisture in the external environment. At the same time, if it is blown by the wind, it is easy to cause insufficient quantity, which makes it difficult to maintain the stability and effectiveness of the accelerator.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This utility model, through the setting of a metering chamber and a quantitative component, connects to an external power source during use. Based on the required weight threshold of the concrete accelerator powder, the third motor is started, flipping the opening and closing plate, allowing the concrete accelerator powder in the conical storage tank to fall onto the weighing platform of the metering chamber.

This helps maintain the stability and effectiveness of the accelerator. Attached Figure Description

The opening and closing plate 11 is flipped to allow the concrete quick-setting agent powder in the conical storage tank 1 to fall onto the weighing platform 403 of the metering chamber 3. The weighing sensor 404 weighs the concrete quick-setting agent powder. After the required measurement is reached, the PLC controller 15 controls the third motor 10 to rotate, close the opening and closing plate 11, start the first motor 401, and flip the weighing platform 403 to the side, allowing the concrete quick-setting agent powder to fall into the sealed conveying pipe 6 below, thereby achieving the function of quantitative conveying. This avoids manual measurement, which is time-consuming and labor-intensive, and helps to liberate labor and improve work efficiency.

[0028] The vibration assembly 8 includes a vibration motor 801 fixedly connected to the surface of the sealed conveying pipe 6. The output end of the vibration motor 801 is splinedly connected to a transmission rod, and one end of the transmission rod is fixedly connected to an eccentric block 802.

In use, the second motor 701 is started, and the spiral conveying rod 702 rotates to seal and convey the concrete accelerator powder. The vibration motor 801 is started, and the centrifugal force generated by the high-speed rotation of the shaft and the eccentric block 802 generates a vibration force, which reduces the blockage and retention of the concrete accelerator powder, ensures the conveying efficiency, and avoids the open conveying of the concrete accelerator, which is exposed to air, moisture and other external elements, as well as wind blowing, which can easily lead to insufficient quantity. This helps to maintain the stability and effectiveness of the accelerator.

[0029] Please see Figure 3 To facilitate the separation of the conical storage tank 1 and the metering chamber 3, a third motor 10 is fixedly connected to one side of the discharge port 2.

[0032] The concrete quick-setting agent delivery device is fixed in place by installing an external connection device on the limiting mounting base, and the support leg 13 supports it.

[0033] Please see Figure 2 The bottom surface of the sealed conveying pipe 6 is fixedly connected to two support springs 16 and a support telescopic rod 17, and the bottom end of the support telescopic rod 17 is fixedly connected to a fixing pile 18.

[0034] The vibration generated by the vibration component 8 causes the support spring 16 to bounce up and down slightly. The support telescopic rod 17 provides a fulcrum for the up and down bounce of the support spring 16, facilitating the conveying of concrete quick-setting agent powder.

[0035] The above parameters and models can be selected according to actual needs.

[0036] Working principle: When in use, connect to an external power source. Based on the required weight threshold of the concrete accelerator powder, start the third motor 10, flip the opening and closing plate 11, and let the concrete accelerator powder in the conical storage tank 1 fall onto the weighing platform 403 of the metering chamber 3. The weighing sensor 404 weighs the concrete accelerator powder. After the required measurement is reached, the PLC controller 15 controls the third motor 10 to rotate, close the opening and closing plate 11, start the first motor 401, and flip the weighing platform 403 to the side, allowing the concrete accelerator powder to fall into the sealed conveying pipe 6 below, thereby achieving the function of quantitative conveying. This avoids manual measurement, which is time-consuming and labor-intensive, and helps to liberate labor and improve work efficiency.

[0037] In use, the second motor 701 is started, and the screw conveyor 702 rotates to convey the concrete accelerator powder in a sealed manner. The vibration motor 801 is started, and the centrifugal force generated by the high-speed rotation of the shaft and eccentric block 802 generates excitation force, producing vibration, reducing the blockage and retention of concrete accelerator powder, ensuring conveying efficiency, and avoiding open conveying of concrete accelerator powder, which is susceptible to contact with air, moisture, and wind in the external environment, which can easily lead to insufficient quantity. This helps to maintain the stability and effectiveness of the accelerator. The above is the working process of the entire device, and the contents not described in detail in this specification are all prior art known to those skilled in the art.
