Description

Technical Field

[0001] This utility model relates to the field of mixing equipment, specifically a device for preparing a mixture for making bricks from silt. Background Technology

[0002] Silt brick making is a technology that processes silt from water bodies such as rivers and lakes into building materials. It involves pre-treating the silt, such as dehydration and impurity removal, then mixing it with additives such as coal slag and straw powder. After aging, the mixture is shaped, dried, and fired to finally produce bricks.

[0003] When making bricks, sludge needs to be mixed with various raw materials. Some of the material will stick to the inner wall of the mixing equipment. This requires scraping the inner wall with a scraper. Over time, the scraper wears down due to contact with the inner wall, resulting in incomplete scraping and reducing the service life of the scraper and the mixing vessel. Therefore, a device is urgently needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a device for preparing a mixture of silt for brick making, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A device for preparing a mixture for silt brick making, comprising a support frame and a mixing vessel. The support frame is fixed to the outside of the mixing vessel. A motor is fixedly installed at the top of the mixing vessel, and a stirring rod is fixedly installed at the output end of the motor. A scraping mechanism for easily scraping the inner wall of the mixing vessel is provided on the outside of the stirring rod. The scraping mechanism includes a cavity, an electric push rod, an extrusion block, an extension rod, a fixing ring, a first movable rod, a spring, a second movable rod, and a scraper. The cavity is opened inside the stirring rod. The electric push rod is fixed at the top of the cavity. The extrusion block is fixed at the lower end of the electric push rod. The extension rod is fixed to the outside of the stirring rod. The fixing ring is fixed inside the extension rod. The first movable rod is movably inserted and inserted at the center of the fixing ring. The first movable rod is tightly attached to the outside of the extrusion block on one side. The second movable rod is movably inserted inside the extension rod and fixed to one side of the first movable rod. The spring is fixed between the second movable rod and the fixed ring and is sleeved on the outside of the first movable rod. The scraper is fixed to the outside of the second movable rod. When in use, the motor is started, and the motor drives the stirring rod to rotate and mix the material. After mixing is completed, the electric push rod is started, and the electric push rod drives the extrusion block to move downward, so that the first movable rod moves along the fixed ring to the outside of the extension rod, driving the second movable rod to move, so that the scraper is tightly attached to the inner wall of the mixing vessel and scrapes the inner wall of the mixing vessel. The scraping work is only performed when in use, and the scraper does not need to be tightly attached to the inner wall of the mixing vessel at all times, thereby extending the service life of the mixing vessel and the scraper.

[0006] Preferably, a feed pipe is fixedly embedded in the top of the mixing vessel, and a sealing cap is screwed onto the top of the feed pipe. During use, the material enters the mixing vessel through the feed pipe.

[0007] Preferably, a solenoid valve is embedded and fixedly installed at the lower end of the mixing vessel, and a discharge pipe is fixedly installed at the lower end of the solenoid valve through a connecting valve. During use, the raw materials after mixing are discharged through the opened solenoid valve.

[0008] Preferably, the extrusion block is a frustum-shaped block.

[0009] Preferably, there are two extension rods, symmetrically fixed on both sides of the stirring rod, and the extension rods are hollow rods.

[0010] Preferably, the electric push rod is electrically connected to an external power source via a conductive ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] When in use, the motor is started, which drives the stirring rod to rotate and mix the materials. After mixing is completed, the electric push rod is started, which drives the extrusion block to move downward, causing the first movable rod to move along the fixed ring to the outside of the extension rod, which in turn drives the second movable rod to move, so that the scraper is in close contact with the inner wall of the mixing vessel and scrapes the inner wall of the mixing vessel. The scraping work is only performed during use, and the scraper does not need to be in close contact with the inner wall of the mixing vessel at all times, thereby extending the service life of the mixing vessel and the scraper.
