Description

Technical Field

[0001] The utility model belongs to the technical field of water reducing agent production equipment, and particularly relates to a mixing device for preparing a polycarboxylic acid high-performance water reducing agent. Background Art

[0002] A water reducer is an admixture that can reduce mixing water consumption and improve concrete strength while maintaining constant concrete workability and cement dosage, or save cement usage while maintaining constant workability and strength. Polycarboxylic acid-based high-performance water reducers are currently the world's most advanced, technologically advanced, promising concrete superplasticizers, boasting the best overall performance. Polycarboxylic acid-based high-performance water reducers are compound products of carboxylic acid-grafted multi-polymers and other effective additives. Performance comparisons with similar products at home and abroad indicate that polycarboxylic acid-based high-performance water reducers have reached internationally advanced levels in terms of technical performance indicators and cost-effectiveness.

[0003] In the prior art, after a general water-reducing agent mixing device has been used for a long time, the interior of the device needs to be cleaned. Manual cleaning is troublesome, and a separate cleaning device requires an additional motor or electrical components to drive it, which increases energy consumption and leads to increased costs. Therefore, a mixing device for preparing a polycarboxylic acid high-performance water-reducing agent is needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a mixing device for preparing a polycarboxylic acid high-performance water-reducing agent, so as to solve the problem that a separate cleaning device requires an additional motor or electrical component to drive it, which increases energy consumption and leads to increased costs.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a mixing device for preparing a polycarboxylic acid high-performance water-reducing agent, comprising a device housing, a top cover fixedly connected to the top of the device housing, a cleaning assembly provided inside the top cover, the cleaning assembly comprising a drive motor, an output end of the drive motor fixedly connected to a rotating shaft, an outer surface of the rotating shaft fixedly connected to a stirring rod, the other end of the stirring rod fixedly connected to a slot block, an annular plate provided inside the device housing, bristles provided on the outer surface of the annular plate, and a card block provided on the inner side of the annular plate.

[0006] As a preferred embodiment, the rotating shaft is rotatably connected in the top cover, the number of the stirring rods is several and they are spaced apart in an upper and lower manner, the number of the bristles is several and they are distributed in a circular array, the length of the stirring rods fits with the inner wall of the annular plate, the bristles fit with the inner wall of the device housing, and the number of the blocks is two and they are symmetrically arranged with each other.

[0007] As a preferred embodiment, a slide groove is opened in the top cover, and a slider is slidably connected in the slide groove. There are two sliders, and they are symmetrically arranged with each other. The bottoms of the two sliders are fixedly connected with connecting blocks, and the bottoms of the connecting blocks are fixedly connected with electric push rods, and the bottom ends of the electric push rods are fixedly connected to the top of the annular plate.

[0008] By providing a slide groove and a slider, when the annular plate rotates, the slider will slide in the slide groove. At the same time, the slider is a "T"-shaped slider to ensure that the slider will not fall out of the slide groove. In this way, the annular plate and the electric push rod can be limited so that they can rotate while maintaining a center of circle.

[0009] As a preferred embodiment, the bottom of the device housing is fixedly connected to an arc-shaped bottom plate, and a discharge pipe is provided in the arc-shaped bottom plate.

[0010] By providing an arc-shaped bottom plate, the discharge pipe is located at the center of the arc-shaped bottom plate. Compared with a flat bottom plate, this can prevent the water reducer in the device from being discharged uncleanly.

[0011] As a preferred embodiment, a water tank is provided at the bottom of the device shell, a water pump is provided on the top of the water tank, a water pipe is provided in the water pump, a hollow plate is clamped at the other end of the water pipe, the hollow plate is located above the annular plate, and a nozzle is provided in the hollow plate. There are several nozzles, and they are distributed in a circular array.

[0012] By providing a water tank, a water pump, a water pipe, a hollow plate and a nozzle, when cleaning the inside of the device shell, the water pump will pump water from the water tank and transport the pumped water to the hollow plate through the water pipe. The water transported to the hollow plate will be sprayed out through the nozzle, so that the bristles can better clean the inside of the device shell. At the same time, the water reducer remaining on the surface of the stirring rod can be cleaned more conveniently.

[0013] As a preferred embodiment, a feeding hopper is provided inside the top cover, and supporting legs are fixedly connected to the bottom of the device housing. The number of the supporting legs is four and they are distributed in a circular array.

[0014] By providing a feeding hopper, one side of the feeding hopper is in the shape of a rectangle extending outward. Compared with the feeding hopper that is overall arc-shaped, this is more convenient for feeding raw materials and has a larger feeding area to prevent leakage of raw materials during the feeding process.

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

[0016] In this utility model, by providing a driving motor, a rotating shaft, a stirring rod, a clamping groove block, an annular plate, bristles and a clamping block, first, the clamping block is clamped into the clamping groove block. Then, the driving motor drives the stirring rod to rotate through the rotating shaft, and the rotating stirring rod drives the annular plate to rotate, so that the bristles on the outer side of the annular plate can clean the inner wall of the device housing. Thus, two functions of stirring and cleaning can be achieved by one motor, without the need to additionally increase motors or electrical components, which is more energy-saving and reduces costs.

[0017] In this utility model, by providing a feeding hopper, one side of the feeding hopper is in a rectangular shape extending outwards. Compared with a feeding hopper with an overall arc shape, this is more convenient for feeding raw materials, has a larger feeding area, and can prevent raw materials from leaking during the feeding process.

[0027] like Figure 3 and Figure 4 When the cam 32 is in the state of rotation and the cam 33 is in the state of rotation, the cam 33 is in the state of rotation and the cam 33 is in the state of rotation. As shown in FIG, a slider 4 is slidably connected in the slide groove 21. The number of sliders 4 is two and they are symmetrically arranged. The bottom of the two sliders 4 are fixedly connected to a connecting block 5. The bottom of the connecting block 5 is fixedly connected to an electric push rod 6. The bottom end of the electric push rod 6 is fixedly connected to the top of the annular plate 34. When it is necessary to clean the inside of the device shell 1, the electric push rod 6 is started. The working electric push rod 6 will drive the annular plate 34 to move downward so that the block 36 on the surface of the annular plate 34 can be stuck in the slot block 331.
