Description

Technical Field

[0001] The utility model relates to the technical field of refractory production, and particularly relates to a surface spraying device for refractory production. Background Technique

[0002] Refractory materials are a class of inorganic non-metallic materials with high temperature resistance, and are widely used in industrial fields such as metallurgy, chemical industry, petroleum, and machinery manufacturing. There are many types of refractory materials, which can be divided into ordinary refractory materials, high-grade refractory materials, and super-grade refractory materials according to different classification standards; or acidic refractory materials, neutral refractory materials, and basic refractory materials. These materials play a crucial role in modern industry. For example, in steel metallurgy, refractory materials are used for the inner lining of the furnace to protect the equipment from the erosion of molten metal; refractory materials can also be sprayed onto the required equipment through a spraying device. Existing spraying devices for refractory materials can filter them, but the filtered impurities need to remove the filter screen to be discharged, with complex operations and affecting work efficiency. Therefore, to solve the above problems, it is necessary to design a surface spraying device for refractory production. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the shortcomings of the existing technology and propose to design a surface spraying device for refractory production, which can discharge the filtered impurities without removing the filter screen and is convenient to operate.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A surface spraying device for refractory production, including a storage tank, further including:

[0006] A filter screen, arranged in the storage tank, including a horizontal part at the center and an inclined part at the edge; the inclined part inclines downward from the horizontal part towards the inner wall of the storage tank and is slidably connected to the inner wall of the storage tank;

[0007] An annular inclined plate, located above the inclined part, the annular inclined plate inclines downward from the inner wall of the storage tank towards the horizontal part and is hinged to the inner wall of the storage tank; the lower surface of the annular inclined plate is connected to the inner wall of the storage tank through a spring, and the annular inclined plate is supported by the spring; the bottom of the annular inclined plate contacts the horizontal part to prevent materials from flowing into the inclined part;

[0008] A stirring shaft, including an upper stirring shaft and a lower stirring shaft, the filter screen penetrates through the stirring shaft and is located at the connection of the upper stirring shaft and the lower stirring shaft, and limiting plates are installed above and below the filter screen to limit the filter screen at the connection of the upper stirring shaft and the lower stirring shaft; the upper stirring shaft is hollow;

[0009] The stirring rod includes an upper stirring rod and a lower stirring rod. The upper stirring rod is hollow inside, located above the filter screen and connected to the upper stirring shaft. There are several spray nozzles at the bottom of the upper stirring rod; the lower stirring rod is arranged on the lower stirring shaft and is used for stirring the material.

[0010] The output pipe has one end connected to one side of the lower end of the storage tank and a nozzle installed at the other end.

[0011] The impurity discharge pipe is arranged on the side of the storage tank and is matched with the filter screen. The impurities on the filter screen are discharged through the impurity discharge pipe.

[0012] In the above technical solution, when it is necessary to remove the impurities on the filter screen, the stirring shaft is moved downward, thereby driving the filter screen to move downward to the position of the impurity discharge pipe. When the filter screen moves downward, a certain distance is formed between it and the annular inclined plate. Then, it is sprayed downward by the nozzle, and the impurities on the horizontal part and the inclined part of the filter screen all enter the impurity discharge pipe through the inclined part, discharging the impurities on the filter screen, and this can be achieved without removing the filter screen. The setting of the inclined part facilitates the downward discharge of impurities. At the same time, the setting of the annular inclined plate can avoid the problem that the excessive falling of materials into the inclined part of the filter screen affects the filtering effect.

[0013] Further, the length of the upper stirring shaft is greater than the inner diameter of the bottom of the annular inclined plate. When the upper stirring shaft moves downward, the two end parts can squeeze the annular inclined plate downward, so that the spray nozzles can spray onto the inclined part, facilitating the discharge of impurities.

[0014] Further, when the stirring shaft moves to the bottom of the storage tank, the position where the filter screen is located is exactly at the impurity discharge pipe, which is convenient for the positioning between the filter screen and the impurity discharge pipe.

[0015] Further, a passive wheel is arranged on the stirring shaft. The passive wheel is located above the storage tank and meshes with the driving wheel. The driving wheel is installed at the output end of the motor, and the motor is installed on the top of the storage tank.

[0016] Further, there is a mounting plate above the passive wheel. The mounting plate is sleeved on the stirring shaft, and limiting plates are installed above and below the mounting plate; an up-and-down driving device is installed on the top of the storage tank. The top of the up-and-down driving device is fixedly connected to the bottom surface of the mounting plate. Through the up-and-down driving device, the mounting plate can be driven to move up and down, thereby driving the stirring shaft to move up and down.

[0017] Further, the up-and-down driving device is an electric telescopic rod or a lifting oil cylinder.

[0018] Further, the top of the stirring shaft is connected to a water pipe.

[0019] Further, the upper stirring shaft and the lower stirring shaft are integrally connected.

[0020] Furthermore, a feed hopper is provided at the top of the storage tank.

[0021] Furthermore, the storage tank is cylindrical.

[0022] Technical effects of the present utility model:

[0023] Compared with the prior art, when impurities on the filter screen need to be removed in the present utility model, the stirring shaft can be adjusted downward, so that the filter screen can be pushed to move downward together until it moves to the impurity discharge pipe. During the downward movement of the filter screen, a certain interval will be generated with the annular inclined plate, and then water is sprayed onto the filter screen through the nozzle. At this time, the impurities located in the inclined part and the horizontal part will enter the impurity discharge pipe with the water flow and thus be discharged. The whole process does not require manually removing the filter screen, which is convenient and efficient. For the design of the present utility model, the setting of the inclined part enables the impurities to flow downward smoothly, while the setting of the annular inclined plate prevents excessive materials from entering the inclined part of the filter screen, enabling it to be filtered by the horizontal part of the filter screen.

Specific embodiments

[0027] To make the purposes, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the specification.

[0028] Embodiment 1:

[0029] As Figure 1 shown, a surface spraying device for refractory material production involved in this embodiment includes a storage tank 1, a filter screen 2, an annular inclined plate 3, a spring 4, a stirring shaft, a stirring rod, an output pipe 7, a nozzle 8, an impurity discharge pipe 9 and a driving device.

[0030] The storage tank 1 is cylindrical, and a feed hopper 16 is provided on one side of the top. A filter screen 2 and an annular inclined plate 3 are arranged inside the storage tank 1. An output pipe 7 and an impurity discharge pipe 9 are provided on the side of the storage tank 1. A pump 17 and a nozzle 8 are installed on the output pipe 7 for material spraying. The impurity discharge pipe 9 cooperates with the filter screen 2 to discharge the impurities on the filter screen 2. When there is too much material in the storage tank 1, the impurity discharge pipe 9 can also be opened to discharge the material outwards.

[0031] The filter screen 2 includes a horizontal part 201 at the center and an inclined part 202 at the edge. Both the horizontal part 201 and the inclined part 202 have a filtering function; the inclined part 202 slopes downwards from the horizontal part 201 towards the inner wall of the storage tank 1 and is slidably connected to the inner wall of the storage tank 1;

[0032] The annular inclined plate 3 is located above the inclined part 202. The annular inclined plate 3 slopes downwards from the inner wall of the storage tank 1 towards the horizontal part 201 and is hinged to the inner wall of the storage tank 1; the lower surface of the annular inclined plate 3 is connected to the inner wall of the storage tank 1 through a spring 4, and the annular inclined plate 3 is supported by the spring 4; the bottom of the annular inclined plate 3 is in contact with the horizontal part 201, which can prevent the material from flowing into the inclined part 202;

[0033] The stirring shaft includes an upper stirring shaft 01 and a lower stirring shaft 02 which are integrally connected. The filter screen 2 penetrates through the stirring shaft and is located at the connection of the upper stirring shaft 01 and the lower stirring shaft 02. Limit plates 15 are installed above and below the filter screen 2 to limit the filter screen 2 at the connection of the upper stirring shaft 01 and the lower stirring shaft 02; the upper stirring shaft 01 is hollow and connected to an external water pipe at the top. The length of the upper stirring shaft 01 is greater than the inner diameter of the bottom of the annular inclined plate 3. When the upper stirring shaft 01 moves downwards, the two end parts can squeeze the annular inclined plate 3 downwards, and the annular inclined plate 3 rotates downwards, so that the spray nozzle 603 can spray onto the inclined part 202 to facilitate the discharge of impurities.

[0034] The stirring rods are arranged on the stirring shaft and include an upper stirring rod 01 and a lower stirring rod 02. The upper stirring rod 01 is hollow, located above the filter screen 2 and communicated with the upper stirring shaft 01. A plurality of spray nozzles 603 are provided at the bottom of the upper stirring rod 01; the lower stirring rod 02 is arranged on the lower stirring shaft 02 for stirring the material.

[0035] To facilitate the accurate positioning between the filter screen 2 and the impurity discharge pipe 9, as Figure 2 shown, when the stirring shaft moves to the bottom of the storage tank 1, the position where the filter screen 2 is located is exactly at the impurity discharge pipe 9, avoiding the problem of difficult impurity discharge due to inaccurate positioning.

[0036] The driving device includes a driven wheel 10, a driving wheel 11, a motor 12, a mounting plate 13 and an up-and-down driving device 14; the motor 12 is installed on the top of the storage tank 1, the driving wheel 11 is installed at the output end of the motor 12, the driven wheel 10 is arranged on the stirring shaft, the driven wheel 10 is located above the storage tank 1 and meshes with the driving wheel 11, and the motor 12 drives the driving wheel 11 to rotate, thereby driving the driven wheel 10 and the stirring shaft to rotate. An installation plate 13 is arranged above the driven wheel 10, the installation plate 13 is sleeved on the stirring shaft, and limiting plates 15 are installed above and below the installation plate 13; the up-and-down driving device 14 is installed on the top of the storage tank 1, the up-and-down driving device 14 adopts an electric telescopic rod, the top of the electric telescopic rod is fixedly connected to the bottom surface of the installation plate 13, and the installation plate 13 is driven to move up and down by the electric telescopic rod, thereby driving the stirring shaft to move up and down. When the stirring shaft moves downward until the driven wheel 10 disengages from the driving wheel 11, the stirring shaft can be manually rotated at this time to realize the conversion between electric and manual operations.

[0037] When the present utility model is in use, the prepared refractory material (mixed with water or other materials) enters the storage tank 1 through the feed hopper 16, the material is filtered by the filter screen 2 to remove impurities, and the material is stirred by the stirring shaft to make the material more uniform, which is beneficial to material spraying. During normal operation, the bottom of the annular inclined plate 3 contacts the horizontal part 201 to prevent the material from flowing into the inclined part 202. When it is necessary to remove the impurities on the filter screen 2, the stirring shaft is moved downward to drive the filter screen 2 to move downward to the impurity discharge pipe 9. When the filter screen 2 moves downward, a certain distance is formed between the filter screen 2 and the annular inclined plate 3, and when the upper stirring shaft 01 moves downward, it can squeeze the annular inclined plate 3 downward, so that the nozzle 8 can spray the horizontal part 201 and the inclined part 202, and the impurities on the horizontal part 201 and the inclined part 202 of the filter screen 2 are discharged into the impurity discharge pipe 9 along with the water flow. A plurality of impurity discharge pipes 9 can be arranged and evenly distributed on the side surface of the tank body 1, which is beneficial to discharging impurities.
