Description

Technical Field

[0001] This utility model belongs to the technical field of water-reducing agent production equipment, and in particular relates to a dripping device for a water-reducing agent reaction vessel. Background Technology

[0002] Water-reducing agents are concrete admixtures that reduce the amount of water used in mixing while maintaining a relatively constant slump. Most are anionic surfactants, including lignin sulfonates, naphthalene sulfonates, and formaldehyde polymers. When added to concrete mixes, they disperse cement particles, improve workability, reduce water consumption per unit area, improve the fluidity of the concrete mix, or reduce the amount of cement used per unit area. Water-reducing agents are available in liquid and powder forms.

[0003] Water-reducing agents come in two forms: aqueous solutions and powders. Aqueous solutions typically have a solids content of 20%, 40% (also known as mother liquor), or 60%, while powders generally have a solids content of 98%. The preparation process of water-reducing agents involves mixing various raw materials in a specific ratio. In existing water-reducing agent production processes, a dripping device is installed on a reaction vessel. Materials A and B are sequentially added to the reaction vessel through this device to mix with other water-reducing agent raw materials.

[0004] In practical work, it has been found that existing dripping devices are mostly located at the top of the reactor. Because the reaction process requires high-speed stirring and the distance between the dripping pipe and the liquid surface is relatively large, the added material often splashes everywhere due to the stirring action, resulting in uneven mixing. Therefore, there is an urgent need to design a dripping device for water-reducing agent reactors to solve these problems. Utility Model Content

[0005] This invention provides a rationally designed dripping device for a water-reducing agent reactor to address technical problems existing in prior art. The height of the dripping head can be freely adjusted according to reaction requirements, preventing the dripped material from splashing onto the reactor body, thus avoiding resource waste and incomplete mixing.

[0006] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is as follows: A dripping device for a water-reducing agent reactor includes a mounting base, a liquid tank mounted on the mounting base, a metering pipeline assembly mounted at the outlet of the liquid tank, and a dripping delivery pipe mounted at the outlet of the metering pipeline assembly; it also includes a height adjustment assembly mounted on the reactor body sealing cover, the movable end of the height adjustment assembly passing through the reactor body sealing cover and mounted with a dripping head, and a telescopic flexible hose installed between the inlet of the dripping head and the outlet of the dripping delivery pipe; a dripping installation port is opened on the reactor body sealing cover, the height adjustment assembly includes a sealing mounting plate fixed to the dripping installation port, a lifting mounting frame fixed to the sealing mounting plate, a screw drive mechanism mounted on the lifting mounting frame and a shaft mounted through the screw drive mechanism, the shaft passing through the sealing mounting plate and being slidably connected to it, and a dripping head mounting plate mounted at the lower end of the shaft, the dripping head mounted on the dripping head mounting plate.

[0007] The advantages and positive effects of this utility model are as follows: This utility model provides a dripping device for a water-reducing agent reactor. A liquid storage tank allows for the storage of the liquid to be added, while a metering pipeline assembly enables its transport. A dripping head connected to the metering pipeline assembly adds the liquid to the reactor according to process requirements. A height adjustment assembly allows for adjustment of the dripping head's height within the reactor, preventing material A (or material B) from splashing during dripping due to stirring, thus improving the uniformity of material mixing and avoiding resource waste. A flexible telescopic hose connects the dripping head and the dripping delivery pipe, allowing for a flexible connection and facilitating the flexible raising and lowering of the dripping head under the height adjustment assembly. In summary, this utility model allows for free adjustment of the dripping head's height according to reaction requirements, preventing material from splashing onto the reactor body, thus avoiding resource waste and incomplete mixing.

[0021] like Figure 1 and Figure 2 As shown, a drip installation port 5 is provided on the sealing cover 3 of the vessel body. The height adjustment component 4 includes a sealing mounting plate 4-2 fixed to the drip installation port 5, a lifting mounting frame 4-3 fixed to the sealing mounting plate 4-2, a screw drive mechanism installed on the lifting mounting frame 4-3, and a shaft 4-8 installed through the screw drive mechanism.

It also includes a drip head mounting plate 4-1 installed at the lower end of the shaft 4-8, and a drip head 2 is installed on the drip head mounting plate 4-1.

[0022] The aforementioned screw drive mechanism includes two sets of longitudinally arranged lifting guide rails 4-4 fixed to the lifting mounting frame 4-3, a lifting moving seat 4-6 slidably connected to the two sets of lifting guide rails 4-4 via a slider, and a shaft 4-8 mounted on the lifting moving seat 4-6 via a shaft seat; it also includes an adjusting screw 4-7 rotatably connected to the lifting mounting frame 4-3 and arranged longitudinally, the lifting moving seat 4-6 being connected to the adjusting screw 4-7 via a screw nut; and an adjusting motor 4-5 mounted on the lifting mounting frame 4-3 for driving the adjusting screw 4-7 to rotate.

[0023] See further Figure 3The aforementioned metering pipeline assembly 9 includes two sets of metering and dispensing structures connected in parallel at the outlet of the liquid tank 8. A main dispensing pipe 9-10 is installed at the outlet of each of the two sets of metering and dispensing structures, and the main dispensing pipe 9-10 is connected to the drip dispensing pipe 6 via a ball valve. The two sets of metering and dispensing structures connected in parallel serve to achieve the function of one working and one standby.

[0024] The aforementioned metering and delivery structure includes an outlet branch pipe 9-1 installed at the outlet of the liquid tank 8. A ball valve and a Y-type filter 9-2 are installed on the outlet branch pipe 9-1. A metering pump 9-3, a diaphragm metering pump, is installed at the outlet of the Y-type filter 9-2 via a pipeline. A delivery pipeline 9-7 is installed at the outlet of the metering pump 9-3. A pulse damper 9-8, a back pressure valve 9-6, and a ball valve are installed on the delivery pipeline 9-7. The outlet of the delivery pipeline 9-7 is connected to the inlet of the main delivery pipeline 9-10. A gauge 9-9 is installed on each pulse damper 9-8 for easy observation by personnel.

[0025] In addition, a pressure relief line 9-4 is installed at the outlet of each metering pump 9-3, connecting it to its inlet. A safety valve 9-5 is installed on the pressure relief line 9-4. Furthermore, the pressure relief line 9-4 is connected to the delivery line 9-7 via a tee fitting. The safety valve 9-5 is a reciprocating safety valve.

[0026] Working principle:

[0027] Before the water-reducing agent is produced, the staff can open the cover of the dosing port on the top of the liquid tank 8, put material A (or material B) into the liquid tank 8 for storage, and then close the cover to prevent material A (or material B) from being contaminated. Then, turn on the motor in the liquid mixing component 7 to mix the material in the liquid tank 8.

[0028] After stirring for a period of time, the metering pump 9-3 and several valves in the metering and delivery structure are turned on. The liquid in the liquid tank 8 is then transported to the dripping head 2 through the dripping delivery pipe 6 and the telescopic hose 1. The liquid is then dripped into the reaction vessel through the dripping head 2. During the liquid transportation process, the liquid is initially filtered by the Y-type filter 9-2 before entering the metering pump 9-3. The back pressure valve 9-6 prevents the agent from flowing back. The pulse damper 9-8 prevents large vibrations in the entire device during operation. The indicator 9-9 allows workers to check the operating status of the device and understand whether there is any blockage. The pressure relief pipeline, which is composed of the pressure relief pipeline 9-4 and the safety valve 9-5, has the liquid inlet of the metering pump 9-3 as the liquid outlet and the liquid outlet of the metering pump 9-3 as the liquid outlet. When a blockage occurs, the pressure relief pipeline will circulate and discharge the liquid to prevent the device from being damaged due to excessive pressure.

[0029] During the dripping process, the height of the dripping head 2 in the reactor is adjusted by the height adjustment component 4 according to the process requirements of the reaction, thereby preventing material A (or material B) from splashing everywhere due to stirring during the dripping process, improving the uniformity of material mixing, and avoiding resource waste.
