Description

Technical Field

[0001] This utility model relates to the field of additive production, and in particular to a novel reaction vessel for concrete additives. Background Technology

[0002] Concrete additives, or admixtures for short, are substances used to improve the performance of concrete. A reaction vessel is a container for physical or chemical reactions. Through the structural design and parameter configuration of the vessel, the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process can be achieved. Concrete additives require the use of reaction vessels for manufacturing during the production process. Currently, during the production of reaction vessels, additives tend to stick to the inner wall of the reaction vessel during the feeding process, making it difficult to clean the inner wall of the reaction vessel in a timely manner. Subsequently, the reaction vessel needs to be disassembled for cleaning, which increases the subsequent operation procedures.

[0003] Currently, a Chinese patent discloses a reaction vessel for producing concrete additives, with application number 2023213213049. By setting up a feeding pipe and a metering structure, when the additive is fed through the feeding pipe, a drive rod drives a cam to rotate. When the cam rotates, it contacts a contact plate, and an auxiliary rod drives a sealing ring to move. When the cam disengages from the contact plate, the sealing ring automatically resets, thereby controlling the amount of additive fed into the feeding pipe and avoiding the possibility of the additive being fed too quickly and failing to react fully.

[0004] Based on the above-disclosed technical solutions, since it is difficult to mix concrete and additives evenly when a single stirring rod stirs in the same direction during the mixing of concrete and additives, and it is difficult to ensure that the mixing quality of the mixture in the upper and lower parts of the reactor is the same, we propose a novel concrete additive reactor to solve this problem. Utility Model Content

[0005] To solve the technical problems of concrete mixing, this utility model provides a novel reaction vessel for concrete additives.

[0006] This utility model is achieved by the following technical solution: a new type of concrete additive reactor, including a reactor body, a feeding mechanism and a motor. A conveying pipe is connected to one side of the top of the reactor body. A filter box is connected to the top of the inner wall of the reactor body through four spring rods. A mud conveying pipe is connected to the other side of the top of the reactor body. An installation box is fixedly connected to the middle of the top of the reactor body.

[0007] The feeding mechanism includes a feeding pipe and a spiral blade. The top of the feeding pipe is connected to the reactor body. One end of the spiral blade is set inside the feeding pipe. A sleeve is fitted on the outside of the spiral blade and is rotatably connected to the inner wall of the reactor body.

[0008] The motor is fixedly connected to the side of the mounting box. A gear set is fixedly connected to the output end of the motor. A solid shaft and a hollow shaft are respectively connected to the bottom of the gear set. A connecting plate is fixedly connected to both sides of the surface of the hollow shaft. A first scraper is fixedly connected to the bottom of one end of the connecting plate. A first stirring rod is fixedly connected at equal intervals to the inner side of the first scraper. A second scraper is fixedly connected to the bottom of the inner side of the first scraper. The solid shaft is inserted through the inner side of the hollow shaft. A connecting plate is fixedly connected to the surface of the solid shaft. A fixing rod is fixedly connected to both sides of the bottom of the connecting plate. The bottom of the fixing rod is slidably connected to the surface of the sleeve. A second stirring rod is fixedly connected at equal intervals to the outer side of the fixing rod.

[0009] As a further improvement to the above solution, the bottom of the filter box is provided with filter holes at equal intervals, and the filter box is located below the feed pipe to shake and screen the additives.

[0010] As a further improvement to the above scheme, the gear set includes an upper bevel gear, a lower bevel gear, and a main bevel gear. The main bevel gear is fixedly connected to the output end of the motor. The upper and lower sides of one end of the main bevel gear mesh with the upper bevel gear and the lower bevel gear, respectively. The upper bevel gear is rotatably connected to the inner wall of the mounting box. The upper bevel gear is fixedly connected to a solid shaft, and the lower bevel gear is connected to a hollow shaft, so that the rotation of the motor drives the solid shaft and the hollow shaft to rotate.

[0011] As a further improvement to the above scheme, the first and second mixing rods are arranged in an alternating manner, and the alternating rotation allows the concrete and additives to be mixed better.

[0012] As a further improvement to the above scheme, the second scraper is set at an angle, and one end of the second scraper is connected to the sleeve to scrape the bottom of the inner wall of the vessel.

[0013] As a further improvement to the above solution, holes are provided on both sides of the bottom of the sleeve, and a groove is provided on the surface of the sleeve for the fixed rod to rotate, so that concrete can enter the sleeve.

[0014] As a further improvement to the above solution, the top of the connecting plate is inclined and the connecting plate abuts against the bottom of the filter box, so that the connecting plate can drive the filter box to vibrate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model uses a solid shaft and a hollow shaft, which respectively drive the second stirring rod, the spiral blade and the first stirring rod to rotate. This allows the concrete and additives below the vessel to be transported to the top of the vessel for mixing while stirring. This solves the problem of ensuring that the mixing quality of concrete and additives is the same at the top and bottom of the vessel, and improves the mixing quality of concrete and additives.

[0017] 2. This utility model uses a filter box and a connecting plate, which causes the filter box to vibrate as the connecting plate rotates. This can disperse the additives and filter impurities, thereby improving the mixing quality of concrete and additives. Attached Figure Description
