Description

Technical Field

[0001] This utility model relates to the field of building surface spraying technology, and in particular to a sand spraying device for imitating a beach in a water park. Background Technology

[0002] Currently, swimming pool surfaces are mainly treated with cyanoacrylate waterproofing and anti-slip technology and polyurea anti-corrosion and anti-slip technology. Both of these technologies can produce smooth, anti-slip, and sand-like anti-slip surfaces according to different requirements. The resulting surfaces are beautiful, safe, water-resistant, and have good decorative effects, which is the latest trend in water park surface and three-dimensional surface treatment.

[0003] Before applying the above-mentioned process to create a sand-like non-slip coating on the swimming pool surface, a base layer needs to be formed by spraying a sandblasting device onto the swimming pool surface. Sandblasting can improve the adhesion between the swimming pool surface and the coating, and also improve the fatigue strength of the base surface, thereby improving the durability of the coating.

[0004] Generally, a sandblasting device includes a container for holding mortar, a pump body for pumping the mortar, and a nozzle connected to the pump body via a pipeline. The pump body pumps the mortar to the nozzle, from which it is sprayed out. The worker holds the nozzle and sprays the mortar evenly onto the base surface to form the base layer. The uniformity of the mortar spraying is crucial to the forming effect and uniformity of the base layer. However, in actual work, when there are large sand particles in the mortar, these large sand particles can clog the nozzle, making it easy for the mortar sprayed by the nozzle to be uneven, thus affecting the construction quality. Utility Model Content

[0005] The purpose of this invention is to solve the above-mentioned problems by providing a sandblasting device for water parks that can effectively filter sand slurry, thereby ensuring the quality of sandblasting.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a sand-spraying device for a water park to simulate a beach, comprising a cavity, and further comprising:

[0007] At least one first discharge port is disposed on the side wall of the cavity;

[0008] A filter element is disposed at one end of the first discharge port located inside the cavity, and is used to filter large particles in the mortar.

[0009] A scraper, adapted to the filter element, is used to scrape the surface of the filter element.

[0010] Specifically, by setting a first discharge port, which is used to connect to the pump body and the nozzle during use, the pump body can pump out the mortar inside the cavity. The mortar can be filtered through the filter element, and large particles are filtered out, thereby solving the problem of nozzle clogging. The filter element is then scraped and cleaned by a scraper to reduce the problem of nozzle filter clogging, ensuring effective filtration of mortar and reducing spraying quality problems caused by partial clogging of the nozzle, thus ensuring construction quality.

[0011] Furthermore, a stirring shaft is provided inside the cavity, and the scraper is driven to be connected to the stirring shaft so as to drive the scraper to periodically pass through the filter element.

[0012] Specifically, by connecting the scraper to the stirring shaft inside the cavity, the stirring shaft can ensure the uniformity of mortar mixing. While the stirring shaft is stirring, it can also drive the scraper to periodically pass over the filter element, which can periodically clean the filter element. The structure is simple and reasonable, cleverly utilizing the stirring shaft to drive the scraper.

[0013] Furthermore, the cavity is a vertically arranged columnar cavity, the stirring shaft is coaxially arranged with the cavity, a connecting sleeve is sleeved on the stirring shaft, the scraper is connected to the connecting sleeve, and the filter element is arranged around the axis of the cavity.

[0014] Furthermore, the filter element includes an outer shell disposed on the first discharge port, the outer shell including an arc-shaped surface facing the stirring shaft and coaxially disposed with the stirring shaft, and a plurality of filter holes are uniformly disposed on the arc-shaped surface.

[0015] Specifically, by setting the filter element to include an arc-shaped surface and setting filter holes on the arc-shaped surface to filter the slurry, this setting allows the entire arc-shaped surface to be scraped when the stirring shaft drives the scraper to move, achieving a better cleaning effect.

[0016] Furthermore, the filter element includes a connecting cylinder, the lower end of which is provided with a flange, and the outer shell is disposed at the other end of the connecting cylinder.

[0017] Specifically, by including a connecting cylinder and a flange in the filter element, it is easy to detachably connect the filter element to the side wall of the cavity, making it convenient to replace and maintain the filter element.

[0018] Furthermore, the outer shell is an annular structure coaxial with the stirring shaft, and both ends of the annular structure are provided with arc-shaped guide surfaces.

[0019] Specifically, by setting up an arc-shaped guide surface, the mortar can be guided, reducing the resistance to the mortar flow and ensuring that the mortar can be uniformly mixed under the stirring action of the mixing shaft, thereby ensuring the construction quality.

[0020] Furthermore, the lower end of the cavity is coaxially connected to a conical funnel-shaped bottom, and a second discharge port is provided at the lowest point of the bottom. The first discharge port is located at the bottom and is higher than the second discharge port.

[0021] Specifically, by setting a conical funnel-shaped bottom and a second discharge port, and setting the first discharge port at a position higher than the second discharge port at the bottom, a switch valve can be set at the second discharge port during use. When the switch valve is closed, the large sand particles filtered by the filter element will be scraped off by the scraper and deposited downwards to the bottom of the conical funnel. After construction is completed, the control valve on the second discharge port is opened to discharge the large sand particles inside, which is convenient for cleaning large particles.

[0022] Furthermore, the connecting sleeve is fitted onto the lower end of the stirring shaft, and a rigid connecting rod is radially arranged on the outer circumferential surface of the connecting sleeve, with the scraper disposed at the end of the connecting rod.

[0023] Specifically, connecting the scraper with the connecting rod reduces the resistance during rotation and minimizes disturbance to the mortar, thus facilitating the downward deposition of large sand particles.

[0024] The sand-spraying device for simulated beaches in water parks disclosed in this utility model has the following advantages compared with the prior art: it can effectively filter large particles in the sand slurry, and the filter element is periodically scraped and cleaned by a scraper to ensure the filtration effect of the filter element. It includes a cavity, at least one first discharge port, which is disposed on the side wall of the cavity; a filter element, which is disposed at one end of the first discharge port located inside the cavity, for filtering large particles in the sand slurry; and a scraper, which is adapted to the filter element for scraping the surface of the filter element.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0032] Please refer to Figure 1-4 The technical solution of this utility model is: a sand-spraying device for a water park to simulate a beach, including a cavity 1, and further including:

[0033] At least one first discharge port 2 is provided on the side wall of the cavity 1;

[0034] Filter element 3 is disposed at one end of the first discharge port 2 located inside the cavity, and is used to filter large particles in the mortar;

[0035] The scraper 4 is adapted to the filter element 3 and is used to scrape the surface of the filter element 3.

[0036] Specifically, it should be noted that the reference is... Figure 1 For example, the top of the cavity is provided with a cover 10, and the cover 10 is provided with an inlet (not shown in the figure) for adding mortar into the cavity 1. In use, mortar is placed inside the cavity 1 through the inlet (not shown in the figure). The cavity is provided with a first outlet 2, which is used to connect to the pump body and the nozzle. The pump body can pump the mortar inside the cavity to the nozzle. The mortar can be filtered through the filter element 3. Large particles are filtered by the filter element 3, thereby solving the problem of nozzle clogging. The filter element is scraped and cleaned by a scraper to reduce the problem of nozzle filter clogging, ensure effective filtration of mortar, reduce the spraying quality problems caused by partial clogging after nozzle clogging, and ensure construction quality.

[0037] Furthermore, as a preferred embodiment, refer to Figure 1 The cavity 1 is provided with a stirring shaft 11, and the scraper 4 is driven to be connected to the stirring shaft 11 so as to drive the scraper 4 to periodically pass through the filter element 3.

[0038] Specifically, for example, the stirring shaft 11 is rotatably mounted on the cover 10. The stirring shaft 11 is driven to rotate by the motor 110, thereby stirring the material inside the cavity. By connecting the scraper 4 to the stirring shaft 11 inside the cavity, the stirring shaft can ensure the uniformity of the mortar mixing. While the stirring shaft 11 is stirring, it can drive the scraper 4 to periodically pass over the filter element 3, and periodically scrape and clean the filter element 3. The stirring shaft 11 is cleverly used to drive the scraper 4 to move, and the structure is simple and reasonable.

[0039] Furthermore, the cavity 1 is a vertically arranged columnar cavity, the stirring shaft 11 is coaxially arranged with the cavity 1, the stirring shaft 11 is fitted with a connecting sleeve 41, the scraper 4 is connected to the connecting sleeve 41, and the filter element is arranged around the axis of the cavity.

[0040] In one specific implementation, the connection between the stirring shaft 11 and the scraper is achieved by a connecting sleeve that fits into the stirring shaft. One of the connecting sleeve and the stirring shaft is provided with a keyway, and the other is provided with a transmission key, thereby achieving a transmission connection. The scraper 4 is placed on the connecting sleeve 41, thereby achieving a transmission connection. When the stirring shaft rotates, it drives the scraper 4 to rotate around the axis of the stirring shaft, so that one scraper can pass through the filter element once in one revolution of the stirring shaft, thereby achieving periodic scraping and cleaning of the filter element.

[0041] Furthermore, as a specific implementation method, refer to Figure 4 , Figure 5 The filter element 3 includes an outer shell 31 disposed on the first discharge port 2. The outer shell 31 includes an arc-shaped surface 310 facing the stirring shaft 11 and coaxially disposed with the stirring shaft. A plurality of filter holes 311 are uniformly disposed on the arc-shaped surface 310.

[0042] Specifically, by setting the filter element to include an arc-shaped surface 310, and setting filter holes on the arc-shaped surface to filter the slurry, this setting allows the entire arc-shaped surface to be scraped when the stirring shaft drives the scraper to move, achieving a better cleaning effect. It should be noted that the outer shell only has filter holes 311 on the arc-shaped surface 310, so filtration is only carried out through the filter holes on the arc-shaped surface, which facilitates cleaning.

[0043] Furthermore, as a specific implementation method, the filter element has the following specific structure: (Refer to...) Figure 4 , Figure 5 The filter element 3 includes a connecting cylinder 32, the lower end of which is provided with a flange 33, and the outer shell 31 is provided at the other end of the connecting cylinder 32.

[0044] Specifically, by including a connecting cylinder and a flange in the filter element, it is easy to detachably connect the filter element to the side wall of the cavity, making it convenient to replace and maintain the filter element.

[0045] Furthermore, as a specific implementation, the outer shell 31 is an annular structure coaxially arranged with the stirring shaft 11, and both ends of the annular structure are provided with arc-shaped guide surfaces 312.

[0046] Specifically, by setting up an arc-shaped guide surface, the mortar can be guided, reducing the resistance to the mortar flow and ensuring that the mortar can be uniformly mixed under the stirring action of the mixing shaft, thereby ensuring the construction quality.

[0047] Furthermore, as a preferred embodiment, refer to Figure 1 The lower end of the cavity 1 is coaxially connected to a conical funnel-shaped bottom 12, and a second discharge port 13 is provided at the lowest point of the bottom 12. The first discharge port 2 is located at the bottom 12 and is higher than the second discharge port.

[0048] Specifically, by setting a conical funnel-shaped bottom and a second discharge port, and setting the first discharge port at a position higher than the second discharge port at the bottom, a switch valve can be set at the second discharge port during use. When the switch valve is closed, the large sand particles filtered by the filter element will be scraped off by the scraper and deposited downwards to the bottom of the conical funnel. After construction is completed, the control valve on the second discharge port is opened to discharge the large sand particles inside, which is convenient for cleaning large particles.

[0049] Furthermore, as a specific embodiment, the connecting sleeve 41 is fitted onto the lower end of the stirring shaft 11, and a rigid connecting rod 410 is radially arranged on the outer circumferential surface of the connecting sleeve, with the scraper 4 disposed at the end of the connecting rod.

[0050] Specifically, connecting the scraper with the connecting rod reduces the resistance during rotation and minimizes disturbance to the mortar, thus facilitating the downward deposition of large sand particles.

[0051] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
