AI Technical Summary
Traditional mixing pumps struggle to deliver precise water, leading to unstable concrete quality. Existing water weighing systems are unable to accurately control the water intake when flow and pressure are unstable.
By adding a buffer hopper to a traditional water weighing system and controlling it with an overflow port and a pneumatic valve, the water supply is cut off in advance when the weighing water is about to reach the set value, and water is slowly replenished through the buffer hopper to achieve precise control of the water inflow.
It enables timed and quantitative water addition by the mixing pump, ensuring stable concrete quality and wider adaptability.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of water supply technology for stirring pumps, specifically a stirring pump with a precise water weighing system. Background Technology
[0002] In modern engineering construction, the performance requirements for materials such as concrete are becoming increasingly stringent. A precise water-cement ratio is a crucial factor in ensuring the strength, durability, and other key properties of concrete. For example, in large-scale projects such as high-rise buildings and bridges, even minor differences in concrete quality can significantly impact the safety and stability of the structure. Traditional water weighing methods are insufficient to meet high-precision requirements, easily leading to inaccurate water usage and consequently affecting concrete quality. Therefore, it is necessary to develop a precise water weighing system to ensure project quality.
[0003] However, the existing devices have the following problems:
[0004] Existing devices mainly add water by means of flow meter, time relay, and weighing. None of these three methods can achieve accurate water addition, which leads to unstable concrete quality. Traditional water weighing systems do not have a buffer hopper. Due to the unstable flow and pressure during water addition, the water intake cannot be accurately controlled from the time the weighing weight reaches the set value until the water circuit is closed.
[0005] Therefore, in order to solve the above problems, a stirring pump with a precise water weighing system is proposed. Utility Model Content
[0006] The purpose of this invention is to provide a stirring pump with a precise water weighing system to solve the water supply problem of the stirring pump in the prior art mentioned in the background section.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a stirring pump with a precise water weighing system, including an overflow port, a buffer water hopper fixedly connected to the outside of the overflow port, a buffer support fixedly connected to the outside of the buffer water hopper, a first pneumatic valve fixedly connected to the bottom of the buffer water hopper, a water hopper support fixedly connected to the bottom of the buffer support, a weighing water hopper fixedly connected to the bottom of the water hopper support, and a second pneumatic valve fixedly connected to the bottom of the weighing water hopper.
[0008] Preferably, a guide port is fixedly connected below the overflow port, and the overflow port and the guide port are hollow tubular structures.
[0009] Preferably, a water bucket fixing column is fixedly connected above the buffer water bucket, and a water bucket guide groove is fixedly connected below the buffer water bucket.
[0010] Preferably, a drain pipe is fixedly connected to the lower part of the water bucket guide groove, and a first pneumatic valve is fixedly connected to the lower part of the drain pipe.
[0011] Preferably, a support top rod is fixedly connected to the top of the cache bracket, and a support base is fixedly connected to the bottom of the cache bracket.
[0012] Preferably, a weighing guide trough is fixedly connected below the weighing hopper, a weighing tube is fixedly connected below the weighing guide trough, and a second pneumatic valve is fixedly connected below the weighing tube.
[0013] Preferably, a bracket fixing plate is fixedly connected to the lower part of the water bucket bracket, and bolt holes are provided inside the bracket fixing plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model adds a buffer water tank to the traditional water weighing system, which cuts off the water supply in advance when the weighed water is about to reach the set value, and the remaining water is slowly replenished by the buffer water tank. The flow rate of the replenished water is much smaller than the initial water flow rate, thereby achieving precise control of the water intake. This device optimizes the water addition method of the mixing pump, so that water can be added on time and in quantity for each operation, and can achieve precise water addition, resulting in more stable concrete quality and wider adaptability.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-6 One embodiment provided by this utility model:
[0024] A stirring pump with a precision water weighing system includes an overflow port 1, a buffer water hopper 2 fixedly connected to the outside of the overflow port 1, a buffer support 3 fixedly connected to the outside of the buffer water hopper 2, a first pneumatic valve 4 fixedly connected to the bottom of the buffer water hopper 2, a water hopper support 6 fixedly connected to the bottom of the buffer support 3, a weighing water hopper 5 fixedly connected to the bottom of the water hopper support 6, and a second pneumatic valve 7 fixedly connected to the bottom of the weighing water hopper 5.
[0025] Furthermore, a guide port 101 is fixedly connected below the overflow port 1. The overflow port 1 and the guide port 101 are hollow tubular structures that can discharge the water overflowing from the buffer water tank 2.
[0026] Furthermore, a water hopper fixing column 201 is fixedly connected above the buffer water hopper 2, and a water hopper guide groove 202 is fixedly connected below the buffer water hopper 2, which can supply water to the weighing water hopper 5.
[0027] Furthermore, a drain pipe 203 is fixedly connected to the lower part of the water bucket guide groove 202, and a first pneumatic valve 4 is fixedly connected to the lower part of the drain pipe 203, which can control the outflow of water.
[0028] Furthermore, a support top rod 301 is fixedly connected to the top of the buffer bracket 3, and a support base 302 is fixedly connected to the bottom of the buffer bracket 3, which can fix the buffer water tank 2.
[0029] Furthermore, a weighing guide trough 501 is fixedly connected below the weighing water hopper 5, a weighing tube 502 is fixedly connected below the weighing guide trough 501, and a second pneumatic valve 7 is fixedly connected below the weighing tube 502 to control the outflow of water.
[0030] Furthermore, a bracket fixing plate 601 is fixedly connected to the lower part of the water bucket bracket 6. The bracket fixing plate 601 has bolt holes inside, which can fix the entire device.
[0031] Working principle: During use, the buffer water tank 2 and the buffer support 3 are rigidly connected and installed together on the water tank support 6. The weighing water tank 5 is connected to the water tank support 6 using a weighing sensor, which can detect the weight of the water in the tank in real time. When weighing water, the water pump draws water and supplies water to both the weighing water tank 5 and the buffer water tank 2 through a three-way valve. The buffer water tank 2 is equipped with an overflow port 1. When the water is full, it overflows into the weighing water tank 5. When the weighing water tank 5 is about to reach the set value, it sends an instruction to the programmable logic controller to stop the water supply. At this time, the water in the buffer water tank 2 is still full. Then, the electronic control system automatically opens the first pneumatic valve 4 at the bottom of the buffer water tank 2, and the remaining water is replenished into the weighing water tank 5 by the buffer water tank 2, ensuring that the weight in the weighing water tank 5 reaches the set value, thus achieving accurate weighing.
