Description

Technical Field

[0001] The utility model belongs to the technical field of waterproof coating production, in particular to a mixer for preparing waterproof coating. Background Art

[0002] Waterproof coating is a one-component water-based waterproof coating made of pure acrylic polymer emulsion as the base material and other additives. After curing, the waterproof coating will become a thin film with certain elongation, elasticity, crack resistance, impermeability and weather resistance, which can play a role in waterproofing, anti-seepage and protection. In the production process of waterproof coating, it needs to be fully mixed to produce waterproof coating, but it still has the following disadvantages in actual use:

[0003] 1. The mixer for preparing waterproof coating directly uses coating for conveying during operation. During the conveying process, a certain amount of coating raw materials is conveyed into the mixer, and then the materials are mixed through proportioning before they can be output. After the materials are output, the materials can be re-input for mixing. The working process is not continuous enough and the efficiency is not high enough;

[0004] 2. During the operation of the mixer for preparing waterproof coatings, the coating to be transported needs to be fully proportioned and accurately quantified to ensure that the amount of coating produced each time is the same. During the production process, the metering operation is not convenient enough. Utility Model Content

[0005] The purpose of the utility model is to provide a mixer for preparing waterproof coatings. By arranging a mixing chamber, a hydraulic cylinder and a fixed cover, the utility model solves the problems that the working process of the mixer for preparing waterproof coatings is not continuous enough, the efficiency is not high enough, and it is not convenient to produce the same amount of coating each time during the working process.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a mixer for preparing waterproof coating, comprising a mixing chamber, a hydraulic cylinder and a fixed cover, wherein the top of the mixing chamber is fixed with the fixed cover, the bottom center of the mixing chamber is fixed with a hydraulic cylinder, a hydraulic rod is movably connected in the hydraulic cylinder, the hydraulic rod is movably connected to the bottom of the mixing chamber through penetration, a lifting piston is fixed on the top of the hydraulic rod, the lifting piston is movably connected in the mixing chamber, a limiting ring 2 is fixed on the inner wall of the mixing chamber above the lifting piston, and a limiting ring 1 is fixed on the inner wall of the mixing chamber below the lifting piston. When working, the raw materials of the coating are contained in the mixing chamber, and the limiting ring 1 and the limiting ring 2 cooperate with each other, so that the amount of coating output each time is the same when the lifting piston driven by the hydraulic rod driven by the hydraulic cylinder works, and the top of the mixing chamber is closed by the fixed cover.

[0008] Furthermore, an output pipe is fixedly connected to the inner wall of the mixing chamber above the second limiting ring, and support columns are fixed in a circular array at the edge of the bottom end of the mixing chamber. The mixing chamber mixes the paint entering therein evenly through the output pipe.

[0009] Furthermore, the bottom end of the mixing chamber is fixedly connected with a one-way input pipe in a circular array, and the bottom ends of all the one-way input pipes are fixedly connected with a connector, and the mixing chamber transports the paint into the mixing chamber through the one-way input pipe.

[0010] Furthermore, the lifting piston is provided with through holes in a ring array, and the through holes are arranged on the outside of the hydraulic rod. The lifting piston conveys the paint mixture through the through holes.

[0011] Furthermore, a blocking piece is provided outside the through hole at the top of the lifting piston, a flexible piece is fixed around the blocking piece, the flexible piece is fixed to the top of the lifting piston, and the lifting piston blocks the through hole through the blocking piece.

[0012] Furthermore, a driving motor is fixed at the top center of the fixed cover, an output end of the driving motor is fixed with an output shaft that passes through and is plugged into the fixed cover, a stirring frame is fixed to the bottom end of the output shaft, and the fixed cover drives the output shaft to rotate through the driving motor, thereby driving the stirring frame to rotate and mixing the paint evenly in the mixing chamber.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model solves the problem that the working process of the mixer for preparing waterproof coating is not continuous and the efficiency is not high enough during the working process by setting a mixing chamber and a hydraulic cylinder. The hydraulic cylinder is started to drive the hydraulic rod to rise, which drives the lifting piston to rise. When the lifting piston rises, the coating is transported to the bottom of the mixing chamber through the one-way input pipe, and the coating to be mixed rises to the stirring frame at the top of the lifting piston, so that the driving motor drives the output shaft to drive the stirring frame to rotate, so that the coating is stirred evenly. In the next working cycle, the stirred material is output through the output pipe. Through continuous working cycles, the material is circulated and output through the output pipe, so that the working process of the mixer for preparing waterproof coating is more continuous and more efficient during the working process.

[0015] 2. The utility model solves the problem that it is inconvenient for a mixer for preparing waterproof coating to produce the same amount of coating each time by arranging a mixing chamber, a hydraulic cylinder and a fixed cover. The raw materials are conveyed into a one-way input pipe, conveyed to the bottom of the mixing chamber through the one-way input pipe, and the hydraulic cylinder is started synchronously. The hydraulic cylinder drives the lifting piston to contact the second limit ring, stops conveying the raw materials, and starts the hydraulic cylinder to press down. The above-mentioned feeding operation is repeated, and the driving motor is started for stirring. After the stirring is completed, the hydraulic cylinder is restarted, and the hydraulic cylinder drives the lifting piston to descend, pushing the mixed coating below it to its top, and then the hydraulic cylinder is started to drive the lifting piston to rise, so that the evenly stirred coating is output through the output pipe, and the insufficiently stirred coating rises to the position of the stirring frame for stirring, so that it is more convenient for the mixer for preparing waterproof coating to produce the same amount of coating each time during operation.

A lifting piston 202 is fixed to the top of the pressure rod 201, and the lifting piston 202 is movably connected in the mixing chamber 1. When the hydraulic cylinder 2 drives the hydraulic rod 201 to rise and fall, the lifting piston 202 is driven to rise and fall in the mixing chamber 1. A limiting ring 2 102 is fixed on the inner wall of the mixing chamber 1 above the lifting piston 202, and a limiting ring 1 101 is fixed on the inner wall of the mixing chamber 1 below the lifting piston 202. The limiting ring 1 101 and the limiting ring 2 102 limit the movement range of the lifting piston 202 in the mixing chamber 1.

[0026] Specifically, an output pipe 103 is fixedly connected to the inner wall of the mixing chamber 1 above the second limiting ring 102, and support columns 106 are fixed in a circular array at the edge of the bottom end of the mixing chamber 1. The mixing chamber 1 outputs the paint through the output pipe 103, and the mixing chamber 1 is supported on the ground by the support columns 106.

[0027] Furthermore, the bottom end of the mixing chamber 1 is fixedly connected to a one-way input pipe 104 in a circular array, and the bottom ends of all the one-way input pipes 104 are fixedly connected to a connector 105, which is connected to a pipe joint for externally transporting raw materials, so that the pipeline for externally transporting raw materials transports the raw materials into the one-way input pipe 104, and then transports them to the bottom of the mixing chamber 1 in one direction through the one-way input pipe 104.
