Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for coating product production, and in particular to an adjustable height radiation-proof powder coating dispersion device. Background Technology

[0002] Radiation-shielding powder coatings are a type of coating with special functions, primarily used to reduce interference and harm from electromagnetic radiation. The following is a detailed introduction to radiation-shielding powder coatings: Radiation-shielding powder coatings typically contain components such as precipitated barium sulfate, which effectively absorb electromagnetic waves, making them suitable for hospitals, laboratories, and other places requiring radiation protection.

[0003] In the preparation of radiation-resistant powder coatings, a disperser is needed to disperse the precipitated barium sulfate in the solution. Chinese utility model patent CN221951038U discloses a disperser for powder coating production, including a base, a hydraulic rod fixedly connected to the top right side of the base, a hydraulic cylinder fixedly connected to the top left side of the base, a transmission box fixedly connected to the top of the hydraulic rod, a sleeve fixedly connected to the bottom right side of the transmission box, a dispersing shaft inside the sleeve, an impeller threadedly connected to the bottom of the dispersing shaft, a threaded hole on the surface of the dispersing shaft, a first arc-shaped block fitted on one side of the dispersing shaft, and a second arc-shaped block fitted on the other side of the dispersing shaft. The detachable and combinable impeller allows for flexible adjustment of the operating position, solving the problems of unsatisfactory dispersion and mixing effects and limited applicability of existing powder coating dispersers. Furthermore, the inclusion of a splash guard improves safety during powder coating dispersion.

[0004] However, the position of the splash guard on the dispersion shaft in the above-mentioned disperser is fixed. When the height of the container loading the coating changes, the splash guard cannot seal the container, which can easily cause the precipitated barium sulfate to splash and affect the radiation protection performance of the powder coating. Therefore, the applicability of the above-mentioned disperser is limited.

[0005] In view of this, there is a need for further improvement of an adjustable-height radiation-resistant powder coating dispersion device to solve the above problems. Utility Model Content

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] An adjustable-height radiation-proof powder coating dispersion device includes a support frame 1, a lifting mechanism, and a stirring mechanism.

[0037] like Figure 1As shown, the lifting mechanism includes a lead screw 2, a first motor 3, and a support base 4; the lead screw 2 is rotatably mounted inside the bracket 1 and always remains vertical; the first motor 3 is mounted on the top of the bracket 1 and is used to drive the lead screw 2 to rotate; one end of the support base 4 is threaded onto the lead screw 2, and the rotation of the lead screw 2 enables the support base 4 to move linearly up and down on the lead screw 2.

[0038] In this embodiment, guide posts 5 are vertically provided on both sides of the lead screw 2 on the bracket 1, and the support seat 4 is slidably sleeved on the lead screw 2, which effectively prevents it from shaking when it moves linearly on the lead screw 2, thus affecting the operation of the stirring mechanism.

[0039] In this embodiment, the output end of the first motor 3 is connected to a reduction gearbox (not shown in the figure). The first motor 3 is connected to the lead screw 2 through the reduction gearbox, which effectively controls the rotational speed of the lead screw 2, making it convenient for the support base 4 to stop at a specified height.

[0040] The stirring mechanism includes a second motor 6, a cover 7, and a dispersing shaft 8; the second motor 6 is mounted on the support base 4 at one end away from the lead screw 2, and the output shaft of the second motor 6 is vertically downward; the end of the output shaft of the second motor 3 is connected to a connector 9, and the cover 7 is threaded onto the connector 9; a sleeve portion 10 is provided at the center of the lower surface of the cover 7, and one end of the dispersing shaft 8 is sleeved onto the sleeve portion 10 and fixed by a screw 11; the dispersing shaft 8 is provided with at least two impellers.

[0041] In this embodiment, as Figure 2 As shown, an annular groove 12 is provided at the bottom edge of the cover 7. The annular groove 12 shares the same axis with the cover 7, and the inner wall of the annular groove 12 is provided with an elastic rubber layer. This arrangement effectively improves the sealing between the cover 7 and the external container containing the coating, and better achieves the dispersion effect.

[0042] In this embodiment, there are two impellers, namely an upper impeller 13 and a bottom impeller 14; the upper impeller 13 is sleeved and fixed on the dispersion shaft 8; the bottom impeller 14 is threaded onto the bottom of the dispersion shaft 8.

[0043] Furthermore, such as Figure 3As shown, the dispersion shaft 8 has several first through holes 15 evenly spaced along the vertical direction, with the axis of the first through holes 15 arranged along the left-right direction of the support 1; the dispersion shaft 8 also has several second through holes 16 evenly spaced along the vertical direction, with the axis of the second through holes 16 arranged along the front-back direction of the support 1, and the first through holes 15 and second through holes 16 correspond one-to-one, with the first through hole 15 located above the corresponding second through hole 16. Bolts 17 are inserted into both the first through holes 15 and the second through holes 16, and nuts 18 are fitted onto the ends of the bolts 17. Figure 4 As shown, the upper impeller 13 is sleeved on the dispersion shaft 8 and fixed by the bolts 17 and nuts 18 on the first through hole 15 and the second through hole 16. This arrangement effectively adjusts the position of the upper impeller 13 on the dispersion shaft 8, allowing for better dispersion of the powder coating. In addition, the first through hole 15 and the second through hole 16 are staggered and separated, which better fixes the upper impeller 13.

[0044] In this embodiment, as Figure 5 As shown, the bottom of the support 1 is provided with an inclined surface 19 on the side near the stirring mechanism to facilitate loading and unloading.

[0045] When dispersing the radiation-shielding powder coating, the container containing the powder coating is pushed into the support 1 through the inclined plane 19 and is located directly below the stirring mechanism. The first motor 3 is started, the support base 4 is lowered until the cover 7 is closed on the top of the container, and then the second motor 6 is started, the dispersion shaft 8 rotates, and the impeller begins to disperse the contents of the container, so that the precipitated barium sulfate is fully mixed in the medium.

[0046] The preferred embodiments of this utility model have been described in detail above, but this utility model is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
