Technical Field

[0001] This utility model relates to the field of concrete processing equipment technology, and in particular to a high-performance concrete admixture batching equipment. Background Technology

[0002] In the concrete production process, admixtures are one of the most important components, and their metering accuracy and mixing uniformity directly affect the final performance of the concrete. Traditional admixture batching equipment mostly uses a single storage tank and a transfer pump, which has the following drawbacks: (1) different types of admixtures are prone to sedimentation and stratification in the tank, resulting in uneven concentration and affecting metering accuracy; (2) the equipment is inconvenient to clean, and residual liquid can easily cause cross-contamination between different batches of admixtures. Therefore, there is an urgent need for a batching equipment with high integration, high efficiency, and easy cleaning that can solve the above problems. Utility Model Content

[0003] This invention provides a high-performance concrete admixture batching equipment, which solves the problems of uneven mixing, easy sedimentation of admixtures, and difficulty in cleaning the inside of the tank in traditional concrete admixture batching equipment.

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-performance concrete admixture batching equipment that is compact in structure, mixes evenly, prevents sedimentation, and is easy to clean.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A high-performance concrete admixture batching device includes a tank. A first outlet, a second outlet, and a third outlet are sequentially arranged on the lower side wall of the tank. A feeding port and a liquid inlet are arranged on the top of the tank. The first outlet is connected to the inlet of a first liquid supply pump via a first outlet pipe. The outlet of the first liquid supply pump is connected to a first liquid outlet pipe and a first drain pipe via a tee fitting. The second outlet is connected to the inlet of a second liquid supply pump via a second outlet pipe. The outlet of the second liquid supply pump is connected to a second liquid outlet pipe. The third outlet is connected to the inlet of a circulating pump via a third outlet pipe. The outlet of the circulating pump is connected to the liquid inlet on the top of the tank via a third liquid outlet pipe. A fourth liquid outlet pipe connects the first and third liquid outlet pipes.

[0006] Furthermore, valves are installed on the first outlet pipe, the second outlet pipe, the third outlet pipe, the first liquid outlet pipe, the first drain pipe, and the fourth liquid outlet pipe.

[0007] Furthermore, the bottoms of the first liquid supply pump, the second liquid supply pump, and the circulation pump are all supported and fixed by support plates fixed to the side wall of the tank.

[0008] Furthermore, an annular diverter pipe is installed at the top of the tank body. The annular diverter pipe is connected to the liquid inlet through a connecting pipe. Multiple swirling nozzles are installed at the bottom of the annular diverter pipe at an angle along the circumference.

[0009] Furthermore, a level gauge is installed on the top of the tank.

[0010] Furthermore, ladders are installed on the side walls of the tank.

[0011] Furthermore, the valve is either a manual valve or a solenoid valve.

[0012] Furthermore, a jacketed cavity is provided on the side wall of the tank, and a spiral coil is installed inside the jacketed cavity.

[0013] The beneficial effects of this utility model are: 1. This utility model achieves multiple functions such as precise output of admixtures, self-circulating mixing of equipment, and rapid drainage and cleaning through three outlets and three pumping pipelines. All pump bodies are integrated and fixed on the tank body through support plates, resulting in a compact structure that reduces the floor space and piping complexity.

[0014] 2. This utility model, through the combination of a circulating pump and a swirling nozzle, can create a swirling flow inside the tank, forcing liquid circulation, effectively breaking up the sedimentation and stratification of additives, ensuring a highly uniform concentration of the solution inside the tank, thereby guaranteeing the accuracy of the dispensing.

[0015] 3. This utility model achieves thorough rinsing of the tank and pipelines by setting up a first drainage pipe and introducing the cleaning liquid into the circulation pipe through a fourth liquid outlet pipe, effectively avoiding cross-contamination between different batches of additives.

[0016] 4. The jacketed cavity and spiral coil of this utility model allow the introduction of heat medium, enabling precise control of the temperature of the admixture inside the tank, meeting the temperature requirements of special formulas for admixtures, and preventing the low-temperature environment from affecting the admixture preparation.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0021] Example 1: like Figure 1-5 As shown, a high-performance concrete admixture batching device includes a tank 1. The lower side wall of the tank 1 is provided with a first outlet, a second outlet, and a third outlet in sequence. The top of the tank 1 is provided with a feeding port and a liquid inlet 2. The first outlet is connected to the inlet of a first liquid supply pump 3 through a first outlet pipe 101. The outlet of the first liquid supply pump 3 is connected to a first liquid outlet pipe 102 and a first drain pipe 103 through a three-way pipe joint 201. The second outlet is connected to the inlet of a second liquid supply pump 4 through a second outlet pipe 104. The outlet of the second liquid supply pump 4 is connected to a second liquid outlet pipe 105. The third outlet is connected to the inlet of a circulating pump 5 through a third outlet pipe 106. The outlet of the circulating pump 5 is connected to the liquid inlet 2 at the top of the tank 1 through a third liquid outlet pipe 107. A fourth liquid outlet pipe 108 is connected between the first liquid outlet pipe 102 and the third liquid outlet pipe 107.

[0022] The tank 1 is a vertical structure. The lower side wall of the tank 1 has a first outlet, a second outlet and a third outlet from top to bottom. The top of the tank 1 is provided with a feeding port for adding powdered or liquid additives and a liquid inlet 2.

[0023] The first outlet is connected to the inlet of the first liquid supply pump 3 via the first outlet pipe 101. The outlet of the first liquid supply pump 3 is divided into two paths via a T-joint 201: one path connects to the first liquid outlet pipe 102 for discharging the additive, and the other path connects to the first drain pipe 103 for discharging wastewater or cleaning water. The second outlet is connected to the inlet of the second liquid supply pump 4 via the second outlet pipe 104. The outlet of the second liquid supply pump 4 is directly connected to the second liquid outlet pipe 105, which can serve as another output or a backup output pipeline. The third outlet is connected to the inlet of the circulation pump 5 via the third outlet pipe 106. The outlet of the circulation pump 5 is connected to the inlet 2 at the top of the tank 1 via the third liquid outlet pipe 107. In addition, a fourth liquid outlet pipe 108 is connected between the first liquid outlet pipe 102 and the third liquid outlet pipe 107.

[0024] To achieve flexible control over each path, see [link / reference]. Figure 5 Valves are installed on the first outlet pipe 101, the second outlet pipe 104, the third outlet pipe 106, the first liquid outlet pipe 102, the first drain pipe 103, the third liquid outlet pipe 107, and the fourth liquid outlet pipe 108. These valves can be manual or solenoid valves. Specifically, a first valve 61 is installed on the first outlet pipe, a second valve 62 on the second outlet pipe 104, a third valve 63 on the third outlet pipe 106, a fourth valve 64 at the lower end of the first liquid outlet pipe 102, a fifth valve 65 on the first drain pipe 103, and a sixth valve 66 on the fourth liquid outlet pipe. A seventh valve 67 is installed at the upper end of the first liquid outlet pipe 102. These valves can be selected as manual or solenoid valves to achieve automated control as needed. To optimize the structure, the first liquid supply pump 3, the second liquid supply pump 4, and the circulation pump 5 are all fixed to the support plate 7 on the side wall of the tank 1 by welding or bolting, achieving stable pump installation.

[0025] As a preferred embodiment of this utility model, see [link to relevant documentation]. Figure 3 , 4 An annular diverter pipe 8 is installed at the top of the tank body 1. The annular diverter pipe 8 is connected to the liquid inlet 2 via a connecting pipe. Multiple swirling nozzles 9 are installed at the bottom of the annular diverter pipe 8 at an angle along the circumference. When liquid is pumped in from the liquid inlet 2, it is sprayed tangentially into the tank through the swirling nozzles 9, creating a swirling flow inside the tank, greatly enhancing the mixing effect. If the cleaning fluid is circulated, it can be used to rinse the inner wall of the tank body 1, quickly cleaning the inner wall.

[0026] Preferably, see Figure 1 , 2A level gauge 10 is installed on the top of the tank 1 to monitor the liquid level in real time and feed the data back to the controller display screen on the side wall of the tank 1. A ladder 11 is welded to the side wall of the tank 1 to facilitate operators to climb to the top of the tank for maintenance and repair. In addition, a jacketed cavity 12 is provided outside the side wall of the tank 1, and a spiral coil 13 is wound inside the jacketed cavity 12. The spiral coil 13 can be used to introduce media such as steam and hot water to heat and insulate the additives in the tank 1, adapting to different ambient temperatures and process requirements.

[0027] Working principle: 1. Mixing mode: Turn on the first liquid supply pump 3 (or the second liquid supply pump 4), the first valve 61 on the first outlet pipe 101, and the fifth valve 65 and the sixth valve 66 on the first liquid outlet pipe 102, and close the other valves. The uniformly mixed additive can be accurately delivered to the point of use through the first liquid supply pump 3.

[0028] 2. Circulation mixing mode: Open the circulation pump 5 and the third valve 63 on the third outlet pipe 106, and close other valves. The liquid at the bottom of the tank is sent to the top of the tank by the circulation pump 5 and sprayed out through the swirling nozzle 9 to form a swirling flow, continuously stirring the liquid to prevent sedimentation and make the composition uniform.

[0029] 3. Cleaning Mode: Close the third outlet valve and open the first drain valve. Cleaning water can be added from the feed port and discharged directly through the first liquid supply pump 3 and the first drain pipe to achieve preliminary cleaning. For deep cleaning, the fourth outlet valve can be opened to allow cleaning water to enter the circulation pipeline, be sprayed out through the swirl nozzle 9 to flush the inner wall of the tank 1, and then discharged through the first drain pipe to achieve thorough cleaning.
