Description

Technical Field

[0001] The utility model relates to the field of concrete processing, in particular to a device for quantitatively adding concrete admixtures. Background Art

[0002] Concrete admixtures are materials added before or during mixing to improve the properties of fresh and hardened concrete. They offer significant benefits despite minimal dosage, significantly enhancing concrete's strength, durability, and workability. Currently, there are numerous types of concrete admixtures, including water reducers, air-entraining agents, accelerators, retarders, and expansive agents, which are widely used in various construction projects.

[0003] In order to improve the strength of concrete during the preparation process, an appropriate amount of admixture is usually added. The existing adding equipment mainly uses a transparent metering tank for quantitative measurement. After repeated use, the transparent metering tank will be attached to the inner wall of the transparent metering tank by the admixture, making it impossible to see the amount of admixture added and quantitatively measure it, resulting in problems with the mixing ratio and reducing production efficiency. In terms of the adding method, it will be transported through a screw feeder, which is prone to uneven feeding and clogging of the machine, reducing the adding efficiency. On the other hand, during use, the transparent metering tank is easily attached to the inner wall of the metering tube by the admixture, reducing its service life.

[0004] Therefore, we have made improvements to this and proposed a quantitative addition device for concrete admixtures. Summary of the Invention

[0005] The purpose of the utility model is to address the current problems that the admixture cannot be quantified, which reduces production efficiency, the addition method is time-consuming and labor-intensive, reduces the addition efficiency, and the admixture easily adheres to and remains on the inner surface of the metering cylinder, reducing its service life.

[0006] In order to achieve the above-mentioned purpose of the invention and improve the above-mentioned problem, the utility model provides a quantitative addition device for concrete admixtures, comprising a support frame, a quantitative component, an addition component, and a cleaning component. The upper end of the support frame is provided with a quantitative component for quantitatively adding admixtures, the side of the quantitative component is provided with an addition component for conveying the admixture to be added to the concrete, and a cleaning component is provided above the addition component for cleaning the admixture attached thereto;

[0007] The quantitative component includes a storage tank arranged at the upper end of the support frame, a moving tube is welded to the bottom end of the storage tank, a quantitative cylinder is arranged inside the moving tube, connecting rods are fixedly connected around the bottom of the quantitative cylinder, and the bottom end of the connecting rod is fixedly connected to a telescopic cylinder.

[0008] As a preferred technical solution of the present application, a circular arc material opening for the entry of additives is opened on the side of the metering cylinder.

[0009] As a preferred technical solution of the present application, a 5mm ventilation hole is opened on the other side of the metering cylinder.

[0010] As the preferred technical solution of the present application, the adding component includes a ventilation pipe arranged on the side of the movable pipe, one end of the ventilation pipe is connected to a high-speed fan, opposite the ventilation pipe there is a pipe connected to an adding pipe on the other side of the ventilation pipe, and one end of the adding pipe is fixedly connected to a flange.

[0011] As a preferred technical solution of the present application, the other end of the ventilation pipe is sleeved with a dustproof net.

[0012] As a preferred technical solution of the present application, the cleaning assembly includes a cleaning pipe arranged above the ventilation pipe, the cleaning pipe is connected to a water pump, and the outer surface of the water pump is sleeved with a water tank.

[0015] As a preferred technical solution of the present application, movable wheels are fixedly installed around the bottom end of the support frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the scheme of this application:

[0018] 1. Through the arrangement of the metering cylinder, storage tank and telescopic cylinder, the telescopic end of the telescopic cylinder drives the metering cylinder to move up and down to continuously take out a certain amount of admixture from the storage tank, thereby achieving rapid quantitative admixture and improving the use efficiency. This solves the problem of the inability to quantify admixtures in the prior art, which reduces production efficiency.

[0019] 2. Through the addition pipe, high-speed fan and ventilation pipe, the high-speed fan generates strong wind and blows it into the metering cylinder in the mobile pipe through the ventilation pipe, so that the admixture in the metering cylinder is blown into the addition pipe and slowly enters the concrete tank. This realizes the wind-powered transportation of admixtures, improves the addition efficiency, and solves the problem that the addition method in the existing technology is time-consuming and labor-intensive, and reduces the addition efficiency;

[0020] 3. Through the provided cleaning pipe, water pump and one-way valve, the one-way valve is opened, and then the water pump is started to extract water from the water storage tank, and then the water is sprayed into the moving pipe and the adding pipe through the clean water pipe for cleaning, thereby processing the residual admixture, achieving the cleaning of the admixture attached to the residual admixture, and improving the service life. This solves the problem in the prior art that the admixture is easy to adhere to the inner surface of the metering cylinder and reduce its service life; BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0032] Example

[0033] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 A concrete admixture quantitative addition device includes a support frame 1, a quantitative component 2, an addition component 3, and a cleaning component 4. The upper end of the support frame 1 is provided with a quantitative component 2 for quantitative addition of the admixture, and the side of the quantitative component 2 is provided with an addition component 3 for transporting the admixture to the concrete. A cleaning component 4 is provided above the addition component 3 for cleaning the admixture.

[0034] The quantitative component 2 includes a storage tank 201 arranged at the upper end of the support frame 1, a mobile tube 205 is welded to the bottom of the storage tank 201, a quantitative cylinder 202 is arranged inside the mobile tube 205, and a connecting rod 203 is fixedly connected to the bottom of the quantitative cylinder 202. The bottom end of the connecting rod 203 is fixedly connected to a telescopic cylinder 204. First, pour the admixture into the storage tank 201, and then start the telescopic cylinder 204, so that the telescopic end of the telescopic cylinder 204 drives the connecting rod 203 to move upward, and then the connecting rod 203 drives the quantitative cylinder 202 to move upward. 02 moves upward in the moving tube 205, causing the metering cylinder 202 to begin to push into the storage tank 201, and then the admixture in the storage tank 201 begins to enter and fill the metering cylinder 202. When the bottom end of the metering cylinder 202 coincides with the top end of the moving tube 205, its telescopic cylinder 204 begins to drive the connecting rod 203 to move downward. At the same time, the connecting rod 203 also drives the metering cylinder 202 to move downward, and then brings the quantitative admixture into the moving tube 205, which can quickly take out the quantitative admixture and improve the use efficiency.

[0035] Further, such as Figure 1 、 Figure 2 and Figure 5 As shown, a 5 mm vent hole 5 is provided on the other side of the metering cylinder 202, and high-speed wind is introduced into the vent hole 5 for conveying and adding, thereby reducing conveying resistance.

[0036] Further, such as Figure 1 and Figure 4 As shown, the adding component 3 includes a ventilation pipe 301 arranged on the side of the mobile pipe 205, one end of the ventilation pipe 301 is connected to a high-speed fan 302, and opposite to the ventilation pipe 301, there is a pipe connected to an adding pipe 303 on the other side of the ventilation pipe 301, and one end of the adding pipe 303 is fixedly connected to a flange 304. First, the flange 304 is connected to the interface of the concrete tank, and then the high-speed fan 302 is manually started to start outputting high-speed airflow. Then, the high-speed fan 302 transports the admixture in the metering cylinder 202 by wind through the ventilation pipe 301, and then transports it to the concrete tank through the adding pipe 303 for mixing with it, which can transport the admixture by wind and improve the adding efficiency.

[0037] Further, such as Figure 1 and Figure 4 As shown, the other end of the ventilation pipe 301 is sleeved with a dustproof net 6, which intercepts the admixture particles and prevents the admixture particles from entering the high-speed fan 302 and causing damage.

[0038] Further, such as Figure 1 and Figure 3 As shown, the cleaning component 4 includes a cleaning pipe 401 arranged above the ventilation pipe 301, and the cleaning pipe 401 is connected to a water pump 402. The outer surface of the water pump 402 is sleeved with a water tank 403. When the water pump 402 is started, the water pump 402 begins to extract water from the water tank 403, and then the water flows out through the clean water pipe to flush the positioning cylinder and the addition pipe 303, thereby cleaning the residual admixture and improving the service life.

[0039] Further, such as Figure 3 As shown, a one-way valve 7 is fixedly installed at one end of the cleaning pipe 401. When the one-way valve 7 is opened, the clean water in the clean water pipe flows into the moving pipe 205 through the one-way valve 7, which can prevent the clean water from flowing back.

[0040] Further, such as Figure 1 and Figure 2 As shown, a baffle 8 is inserted into the side of the movable tube 205. The baffle 8 is manually slid downward to block the inlet of the ventilation tube 301 to prevent the water flow from entering the high-speed fan 302 during cleaning.

[0041] Further, such as Figure 1 As shown, movable wheels 9 are fixedly installed around the bottom of the support frame 1. The support frame 1 can be moved in multiple directions through the movable wheels 9, which is convenient for use.

[0042] The use process of the concrete admixture quantitative addition equipment provided by the utility model is as follows:

[0043] Manually push the support frame 1 so that the support frame 1 drives the entire device to a certain place through the moving wheel 9, first pour the admixture into the storage tank 201, then start the telescopic cylinder 204, so that the telescopic end of the telescopic cylinder 204 drives the connecting rod 203 to move upward, and then the connecting rod 203 drives the metering cylinder 202 to move upward in the moving tube 205, so that the metering cylinder 202 begins to be pushed into the storage tank 201, and then the admixture in the storage tank 201 begins to be quickly filled into the metering cylinder 202 through the arc material port. When the bottom end of the metering cylinder 202 coincides with the top end of the moving tube 205, its telescopic cylinder 204 starts to drive the connecting rod 203 to move downward, and at the same time, the connecting rod 203 also drives the metering cylinder 202 to move downward, and then brings the quantitative admixture into the moving tube 205, and the flange 304 is connected to the interface of the concrete tank, and then the high-speed fan 302 is manually started to make the high-speed fan 302 start to output high-speed airflow, and the ventilation hole 5 on the side of the metering cylinder 202 allows high-speed wind to enter, and then the high-speed fan 302 transports the admixture in the metering cylinder 202 through the ventilation pipe 301, and then transports it to the concrete tank through the adding pipe 303 to mix with it. After adding, the flange 304 is manually removed so that the flange 304 no longer connects the adding pipe 303 to the inlet of the concrete tank, and the baffle 8 is manually slid downward to block the inlet of the ventilation pipe 301. Then the water pump 402 is started to make the water pump 402 start to pump water from the water tank 403, and at the same time, the one-way valve 7 is opened, and then the water flows out through the clean water pipe to flush the positioning cylinder and the adding pipe 303.
