Description

Technical Field

[0001] The utility model belongs to the technical field of glass thinning and etching, and more specifically relates to a glass thinning and etching spraying device. Background Art

[0002] In recent years, the production process and equipment level of glass have been continuously improved. The panel industry has developed rapidly, and the domestic production capacity has increased. With the production needs, most panels need to be thinned, that is, thinned and etched by chemical liquid; among them, spray etching is more advantageous, which is to draw the liquid through a pump and evenly etch the product by spraying acid mist from the top through the nozzle. This solution can efficiently thin the product and reduce the damage to the product caused by shaking; the current method of adding a rotor inside the nozzle to achieve uniform spraying has the risk of clogging the nozzle, which needs to be optimized and improved.

[0003] The design of the spray nozzle for spraying in the prior art is to add a fixed rotor in the nozzle so that the water flow forms a spiral flow and is sprayed through a high-pressure nozzle. This has major defects: Disadvantage 1: The rotor is in close contact with the nozzle, and the rotor is easily stuck, causing blockage; Disadvantage 2: It is difficult to maintain, and the rotors need to be disassembled and cleaned one by one and then reinstalled during maintenance.

[0004] There is a technology named "fire sprinkler" and the publication number is "CN102614611B" in the prior art, which discloses a fire sprinkler, including a sprinkler with a water inlet pipe, a water outlet is provided on the sprinkler, and the sprinkler is composed of a connection plate, a sprinkler upper body and a sprinkler lower body from top to bottom, the connection plate is set on the water inlet pipe, the water outlet of the sprinkler upper body is provided on the side wall, and the water outlet of the sprinkler lower body is provided at the bottom center; an annular inclined plate is obliquely provided in the upper cavity of the sprinkler. An annular groove is provided on the joint surface of the connection plate and the water inlet pipe, and balls are arranged in a bushing with an L-shaped cross section buckled in the annular groove. A retaining spring is provided in the annular groove provided on the inner wall of the connection plate close to the sprinkler upper body. The advantages of the present invention are fast response speed, safety and reliability, large protection radius, uniform water spraying, and high fire extinguishing efficiency; the installation height can reach 6-25 meters, which is particularly suitable for large spaces and large open fields that cannot be protected by conventional sprinklers. However, this technology does not involve the technical problems and technical solutions of the present application. Utility Model Content

[0005] The technical problem to be solved by the utility model is: in view of the deficiencies in the prior art, a glass thinning etching spray device is provided which has a simple structure, effectively reduces the occurrence of nozzle clogging, and is easy to clean and maintain while ensuring convenient and reliable spraying of glass thinning etching liquid.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the utility model is:

[0007] The utility model discloses a glass thinning and etching spraying device, wherein a spray head body comprises a spray cavity, a movable ball is arranged in the spray cavity, a plurality of anti-blocking supports are arranged on the inner wall of the connecting bottom surface connected to the lower part of the spray cavity, the connecting bottom surface at the lower part of the spray cavity is externally connected to a nozzle, and the nozzle is connected to the spray cavity.

[0008] The upper part of the nozzle body is connected to the medicine liquid delivery pipeline.

[0009] The nozzle is a bell-mouth structure, and the cross-sectional area of ​​one end of the nozzle connected to the connection bottom surface is set to be larger than the cross-sectional area of ​​the lower end of the nozzle.

[0010] The spray cavity is a cylindrical structure or a square structure.

[0011] When the spray cavity is a cylindrical structure, the diameter of the movable ball is smaller than the diameter of the horizontal section of the nozzle body; when the spray cavity is a square structure, the diameter of the movable ball is smaller than the side length of the horizontal section of the nozzle body.

[0012] An opening is arranged on the connecting bottom surface, and a plurality of anti-blocking supports are arranged at intervals along the inner wall of the connecting bottom surface at the opening position, and the anti-blocking supports are spherical structures.

[0013] The opening is a circular structure, and a plurality of anti-blocking supports are arranged at intervals along the inner wall of the bottom surface near the edge of the opening.

[0014] The movable ball is a structure made of PVC material.

[0015] The connection bottom surface is connected to the lower end of the nozzle body through a threaded structure.

[0016] The nozzle is connected to the connection bottom surface by welding.

[0017] The technical solution of the utility model is adopted, and the working principle and beneficial effects are as follows:

[0018] The glass thinning and etching spray device described in the utility model is improved in the structural setting of the nozzle body. A spray cavity with a hollow structure is set inside the nozzle body, and a movable ball is placed in the spray cavity. The lower part of the spray cavity of the nozzle body is connected to the connecting bottom surface. The inner wall of the connecting bottom surface is provided with multiple anti-blocking supports. The anti-blocking supports are structures protruding from the inner wall of the connecting bottom surface, which support the movable ball and prevent the movable ball from contacting the connecting bottom surface. The connecting bottom surface at the lower part of the spray cavity is externally connected to a nozzle, and the nozzle is used to spray the liquid medicine transported through the spray cavity. With such a structure, after the pressurized liquid medicine is transported into the nozzle body, the liquid medicine drives the movable ball to rotate continuously, and the movable range of the movable ball is limited by the spray cavity, thereby playing a certain blocking role on the liquid medicine, increasing the pressure of the liquid medicine when it is sprayed from the nozzle, and improving the spraying effect. Because the anti-blocking support protrudes from the inner wall of the connection bottom surface, it can effectively support the movable ball, so that there is always a gap between the movable ball and the connection bottom surface, ensuring that the movable ball will not block the outlet between the spray cavity and the nozzle. When there are too many impurities in the spray cavity, the connection bottom surface and the spray body are separated, and the inside of the spray body can be cleaned, or the movable ball can be cleaned or replaced, making the cleaning and maintenance of the entire device convenient, and the manufacturing cost of the device is low.

[0023] The following is a detailed description of the embodiments of the present invention, such as the shapes, structures, positions and connection relationships of the components involved, the functions and working principles of the components, etc., by referring to the accompanying drawings:

[0024] As attached Figure 1 , Attachment Figure 2As shown, the utility model is a glass thinning and etching spraying device, the nozzle body 1 includes a spraying cavity 2, a movable ball 3 is arranged in the spraying cavity 2, a plurality of anti-blocking supports 5 are arranged on the inner wall of the connecting bottom surface 4 connected to the lower part of the spraying cavity 2, and a nozzle 6 is connected to the outer side of the connecting bottom surface 4 at the lower part of the spraying cavity 2, and the nozzle 6 is connected to the spraying cavity 2. The above structure proposes an improved technical solution to the deficiencies in the prior art. When the structure is set, the nozzle body is improved, the spraying cavity 2 with a hollow structure is arranged inside the nozzle body 1, a movable ball 3 is placed in the spraying cavity 2, and the lower part of the spraying cavity 2 of the nozzle body 1 is connected to the connecting bottom surface 4, and a plurality of anti-blocking supports 5 are arranged on the inner wall of the connecting bottom surface 4, and the anti-blocking supports 5 are structures protruding from the inner wall of the connecting bottom surface 4, so as to support the movable ball 3 and prevent the movable ball 3 from contacting the connecting bottom surface 4, and the connecting bottom surface 4 at the lower part of the spraying cavity 2 is connected to the outer side of the nozzle 6, and the nozzle 6 is used to spray the liquid transported through the spraying cavity 2. With such a structure, after the pressurized liquid medicine is delivered to the nozzle body 1, the liquid medicine drives the movable ball 3 to rotate continuously, and the movable range of the movable ball 3 is limited by the spray cavity 2, thereby playing a certain blocking role on the liquid medicine, increasing the pressure of the liquid medicine when it is sprayed from the nozzle 6, and improving the spraying effect. Because the anti-blocking support 5 protrudes from the inner wall of the connecting bottom surface 4, it can effectively support the movable ball 3, so that there is always a gap between the movable ball 3 and the connecting bottom surface 4, ensuring that the movable ball 3 will not block the outlet between the spray cavity 2 and the nozzle 6. When there are too many impurities in the spray cavity 2, the connecting bottom surface 4 and the spray body 1 are separated, and the inside of the spray body 1 can be cleaned, or the movable ball 3 can be cleaned or replaced, so that the cleaning and maintenance of the entire device are convenient, and the manufacturing cost of the device is low. The glass thinning and etching spraying device described in the utility model has a simple structure, and on the premise of ensuring convenient and reliable spraying of the glass thinning and etching liquid, it effectively reduces the occurrence of nozzle blockage and is easy to clean and maintain.

[0025] The upper part of the nozzle body 1 is connected to the liquid medicine delivery pipeline 7. In the above structure, the liquid medicine delivery pipeline 7 is used to deliver the liquid medicine to the spray cavity of the nozzle body, and then spray it out from the nozzle 6.

[0026] The nozzle 6 is a bell-shaped structure, and the cross-sectional area of ​​the end where the nozzle 6 is connected to the connection bottom surface 4 is set to be larger than the cross-sectional area of ​​the lower end of the nozzle 6. In the above structure, the nozzle is set to a bell-shaped structure, which effectively improves the coverage range during spraying and ensures the spraying effect.

[0027] The spray cavity 2 is a cylindrical structure or a square structure. When the spray cavity 2 is a cylindrical structure, the diameter of the movable ball 3 is smaller than the diameter of the horizontal section of the spray head body 1. When the spray cavity 2 is a square structure, the diameter of the movable ball 3 is smaller than the side length of the horizontal section of the spray head body 1. In the above structure, on the one hand, the movable ball 3 can rotate continuously in the spray cavity. On the other hand, the movable range of the movable ball 3 is limited by the spray cavity 2, which has a certain blocking effect on the liquid medicine and increases the pressure of the liquid medicine when it is sprayed from the nozzle 6.

[0028] The connecting bottom surface 4 is provided with an opening 8, and the inner wall of the connecting bottom surface 4 is provided with a plurality of anti-blocking supports 5 at intervals along the position of the opening 8, and the anti-blocking supports 5 are spherical structures. The above structure, the provision of a plurality of anti-blocking supports, can reliably support the movable ball, and the anti-blocking supports 5 are spherical structures, and the movable ball is also a spherical structure. When the anti-blocking supports contact the movable ball, there will be no sharp collision, and the movable ball will not be damaged, thereby increasing the service life of the movable ball.

[0029] The opening 8 is a circular structure, and a plurality of anti-blocking supports 5 are arranged at intervals along the inner wall of the bottom surface 4 near the edge of the opening 8. In the above structure, the plurality of anti-blocking supports 5 are arranged along the opening, so that the movable ball can be reliably supported at any rotation.

[0030] The movable ball 3 is made of PVC material. In the above structure, the movable ball made of PVC material has the effect of acid and alkali resistance, which effectively increases the service life of the movable ball.

[0031] The connection bottom surface 4 is connected to the lower end of the nozzle body 1 through a threaded structure. The nozzle 6 is welded to the connection bottom surface 4. With the above structure, the connection bottom surface 4 and the nozzle body 1 can be reliably connected or disassembled by twisting the connection bottom surface 4, which is convenient for quick maintenance.

[0032] The glass thinning and etching spraying device described in the utility model is improved in the structural setting of the nozzle body 1. A spraying cavity 2 with a hollow structure is arranged inside the nozzle body 1, and a movable ball 3 is placed in the spraying cavity 2. The lower part of the spraying cavity 2 of the nozzle body 1 is connected to the connecting bottom surface 4. A plurality of anti-blocking supports 5 are arranged on the inner wall of the connecting bottom surface 4. The anti-blocking supports 5 are arranged to be a structure protruding from the inner wall of the connecting bottom surface 4, so as to support the movable ball 3 and prevent the movable ball 3 from contacting the connecting bottom surface 4. The connecting bottom surface 4 at the lower part of the spraying cavity 2 is externally connected to a nozzle 6, and the nozzle 6 is used to spray the liquid medicine transported through the spraying cavity 2. With such a structure, after the pressurized liquid medicine is transported into the nozzle body 1, the liquid medicine drives the movable ball 3 to rotate continuously, and the movable range of the movable ball 3 is limited by the spraying cavity 2, thereby playing a certain blocking role on the liquid medicine, increasing the pressure of the liquid medicine when it is sprayed from the nozzle 6, improving the spraying effect, and being reliable in use. Because the anti-blocking support 5 protrudes from the inner wall of the connecting bottom surface 4, it can effectively support the movable ball 3, so that there is always a gap between the movable ball 3 and the connecting bottom surface 4, ensuring that the movable ball 3 will not block the outlet between the spray cavity 2 and the nozzle 6. When there are too many impurities in the spray cavity 2, the connecting bottom surface 4 and the spray body 1 are separated, and the inside of the spray body 1 can be cleaned, or the movable ball 3 can be cleaned or replaced, making the cleaning and maintenance of the entire device convenient, and the manufacturing cost of the device is low.

[0033] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
