Description

TECHNICAL FIELD

[0001] The application relates to the technical field of dispersing devices, in particular to a dispersing device for water-based paint production. BACKGROUND

[0002] Water-based paint is a kind of paint with water as solvent or dispersion medium, which has the characteristics of environmental protection, safety, easy cleaning and the like. The working process of a water-based paint production line usually includes the following main steps: dispersion, grinding, color adjustment, mixing and filtering. Dispersion is to disperse solid particles such as pigments and resins in water under high-speed stirring to form a uniform suspension. Grinding is to further refine the dispersed pigments using grinding equipment to improve the gloss and uniformity of the paint. Color adjustment is to adjust the proportion of pigments according to the required color to ensure the color consistency of the paint. Mixing is to mix all ingredients uniformly to ensure the stability and performance of the paint. Filtering is to remove impurities and incompletely dispersed particles in the paint through filtering equipment.

[0003] The dispersing device generally refers to a device for uniformly dispersing solid particles such as pigments and fillers in liquid medium (such as water or solvent). The existing dispersing device is generally a high-speed dispersing machine, which mainly includes a rack, a main shaft, a dispersing disc, a motor, a speed reducer, a stirrer and a container. The rack is the support structure of the whole device, which is usually made of steel to ensure the stability and durability of the device. The main shaft mainly connects the dispersing disc and the motor to transmit the power of the motor to the dispersing disc for high-speed rotation. The dispersing disc is located at the bottom of the container and is usually made of stainless steel or other corrosion-resistant materials. The design of the dispersing disc has an important influence on the dispersing effect, and common ones include flat disc, sawtooth disc and anchor disc. The motor is a device that provides power for the dispersing machine, and is usually an explosion-proof motor to adapt to the possible flammable and explosive environment. The speed reducer converts the high-speed rotation of the motor into the low-speed rotation of the dispersing disc to meet the needs of dispersing operation. The stirrer is used for auxiliary mixing and dispersing. The container is usually made of stainless steel and is used to hold the materials to be dispersed.

[0004] The existing high-speed dispersing machine generally adjusts the height of the dispersing disc through a hydraulic or pneumatic system to facilitate the adjustment of the relative position height of the dispersing disc and the container. The position of the dispersing disc is adjusted by controlling the extension and retraction of the hydraulic cylinder or air cylinder, but when the liquid level in the container is low, the dispersing disc is difficult to reach the stirring position due to the limitation of the contraction amount of the hydraulic or pneumatic system of the high-speed dispersing machine, and a longer main shaft is generally needed to make the dispersing disc reach the stirring position, thereby affecting the work efficiency. Invention content

[0034] The embodiment of the present application discloses a dispersion device for water-based paint production.

[0035] The dispersion device for water-based paint production comprises a rack 1, a main shaft, a dispersion disc, a motor 2, a container 3, a displacement assembly 4, a guide assembly 5 and an adjusting assembly 6. The rack 1 is fixedly installed on the ground, the motor 2 is fixedly installed on the rack 1, the dispersion disc is connected with the motor 2 through the main shaft, and power transmission is realized.

[0036] The displacement assembly 4 is used for moving the container 3 along a predetermined track, the guide assembly 5 and the adjusting assembly 6 are both fixedly installed on the displacement assembly 4, the guide assembly 5 is used for guiding the container 3 and improving the working stability of the container 3, and the adjusting assembly 6 is used for adjusting the position of the container 3 in the vertical direction.

[0037] When it is necessary to adjust the position of the container 3 in the vertical direction, the container 3 is first moved to the position directly below the dispersion disc through the displacement assembly 4. Then, fine adjustment is performed by using the adjusting assembly 6, so as to ensure accurate positioning of the container 3. In this process, the guide assembly 5 provides stable guiding action.

[0038] The displacement assembly 4 comprises a guide rail 41, a support platform 42 and a driving unit.

[0039] The guide rail 41 is fixedly installed on the ground, the support platform 42 is provided with a roller at the bottom, and the roller and the guide rail 41 are in rolling cooperation. In the embodiment of the application, the driving unit is a driving motor, the driving motor is installed on the top of the support platform 42, and the driving motor and the roller are in transmission cooperation, so that the support platform 42 is moved on the guide rail 41 by the driving motor.

[0040] The guide assembly 5 is provided with a plurality of guide assemblies 5, the plurality of guide assemblies 5 are distributed in the circumferential direction along the axis direction of the container 3, and in the embodiment of the application, the guide assembly 5 is provided with three guide assemblies.

[0041] Each guide assembly 5 comprises a guide cylinder 51 and a guide rod 52.

[0042] The guide rod 52 is vertically fixedly installed on the support platform 42, the guide cylinder 51 is fixedly installed on the outer ring wall of the container 3, and the guide rod 52 and the guide cylinder 51 are in sliding cooperation.

[0043] In order to improve the smoothness of the relative sliding of the guide rod 52 and the guide cylinder 51, an oil injection hole 511 is formed in the side wall of the guide cylinder 51, the oil injection hole 511 is a through hole, and an oil injection groove 512 is formed in the inner wall of the guide cylinder 51.

[0044] When it is necessary to lubricate between the guide rod 52 and the guide cylinder 51, the oil is injected into the guide rod 52 and the guide cylinder 51 through the oil injection hole 511, and the injected oil moves inside the oil injection groove 512, so as to increase the contact area of the oil and the guide rod 52 and improve the lubricating effect. At the same time, the guide groove can also collect impurities on the guide rod 52, so as to reduce the possibility that the impurities on the guide rod 52 wear the inner wall of the guide cylinder 51. When the oil is injected, the oil will discharge the collected impurities inside the guide groove to the outer wall of the guide cylinder 51, so as to facilitate the cleaning of the staff.

[0045] The adjusting assembly 6 comprises a telescopic part 61 and a support plate 62.

[0046] The telescopic part 61 is vertically arranged, and in the embodiment, the telescopic part 61 is a multi-stage telescopic oil cylinder. The bottom of the multi-stage telescopic oil cylinder is fixedly installed on the support platform 42, and the support plate 62 is fixedly installed on the top of the multi-stage telescopic oil cylinder. The bottom of the support plate 62 abuts against the bottom of the container 3.

The guide rods 52 and the limiting cylinders 621 are in sliding fit. When the support plate 62 supports the container 3, the guide rods 52 and the limiting cylinders 621 limit the support plate 62 in cooperation, so as to improve the working stability of the support plate 62.

[0048] An observation window 31 is designed on the side wall of the container 3 and is made of transparent chemical corrosion-resistant material. In the embodiment, water-based acrylic resin is used, so as to observe the dispersion state of the paint and the position of the dispersion disc and ensure the safety during operation.

[0049] The implementation principle of the dispersion device for water-based paint production provided in the embodiments of the present application is as follows: when the position of the container 3 in the vertical direction needs to be adjusted, first, the driving motor is used to drive the supporting platform 42 to move through the rollers, so that the container 3 is accurately moved to be directly below the dispersion disc. Next, the multi-stage telescopic oil cylinder pushes the container 3 to move in the vertical direction through the supporting plate 62. In the process of moving the supporting plate 62, the limiting cylinder 621 guides and limits the supporting plate 62, so as to reduce the risk of tilting of the supporting plate 62. In the process of moving the container 3, the guiding rod 52 precisely guides the container 3 through the guiding cylinder 51, so as to improve the working stability of the container 3. In order to improve the lubricating effect between the guiding rod 52 and the guiding cylinder 51, oil is injected into the inner wall of the guiding cylinder 51 through the oil injection hole 511. The movement of the oil in the inner wall of the oil injection groove 512 increases the contact area between the oil and the guiding rod 52, so as to improve the lubricating effect. At the same time, the process of injecting oil also helps to discharge impurities in the oil injection groove 512, so as to facilitate the staff to clean the impurities between the guiding rod 52 and the guiding cylinder 51. When the relative position of the container 3 and the dispersion disc needs to be adjusted, the observation window 31 can be used for observation, so as to ensure the safety of the operation and facilitate the observation of the dispersion effect of the liquid.
