Description

Technical Field

[0001] This utility model relates to the field of bleaching devices, specifically a green and environmentally friendly bleaching device for kaolin. Background Technology

[0002] Kaolin, also known as dolomite, Guanyin clay, and pottery clay, is a non-metallic mineral primarily composed of kaolinite group clay minerals and rich in minerals such as silicon, aluminum, zinc, and magnesium. Kaolin has a wide range of applications, mainly in the paper, ceramics, and refractory materials industries, and secondarily in coatings, rubber fillers, enamel glazes, and as a raw material for white cement.

[0003] The higher the whiteness, purity, and particle size of kaolin, the better its quality and the higher its market price. However, natural kaolin often contains mineral impurities such as iron and titanium, which reduce its whiteness and affect its application in high-end fields. Therefore, kaolin often needs to be bleached during processing to improve its whiteness.

[0004] In existing technologies, bleaching agents are usually added to kaolin for bleaching. However, during use and observation, it has been found that when the reagent reacts chemically with impurities in the kaolin, it releases heat. When the temperature in the mixture is too high, it accelerates the decomposition of the bleaching agent and reduces the bleaching effect of the kaolin.

[0005] Therefore, a green and environmentally friendly bleaching device for kaolin is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A green and environmentally friendly bleaching device for kaolin, comprising a tank body, a first inlet at the top of the tank body, a second inlet at the top of the tank body, a discharge pipe connected to the bottom of the tank body, a support fixedly connected to the top of the tank body, a motor mounted on the top of the support, a rotating shaft rotatably connected through the middle of the support, a belt sleeved between the rotating shaft and the motor, multiple sets of stirring blades fixedly connected to the middle of the rotating shaft, an air inlet pipe connected to the top of the rotating shaft, a rotatable connection between the air inlet pipe and the rotating shaft, a connecting ring fixedly connected to the middle of the rotating shaft, a communication between the rotating shaft and the connecting ring, and multiple air outlet pipes connected to the middle of the connecting ring; multiple holes are formed in the inner wall of the air outlet pipes. Through the communication between the air inlet pipe and the air outlet pipes, the cooling airflow can uniformly cool the material inside the tank body, improving the cooling effect of the device on the material and also improving the bleaching effect of the device on kaolin.

[0008] Preferably, multiple elastic ropes are fixedly connected inside the vent pipe; a sphere is fixedly connected to the end of each elastic rope; the sphere and the hole are correspondingly arranged; through the cooperation of the elastic ropes and the sphere, the sphere will seal the hole inside the vent pipe under normal conditions, reducing the possibility of material entering the vent pipe through the hole, thereby reducing the possibility of contamination inside the vent pipe.

[0009] Preferably, a positioning plate is fixed to the inner wall of the hole; the inner wall of the positioning plate has an arc-shaped structure; by setting the positioning plate, when the device stops cooling the material, the ball will reset under the elastic force of the elastic rope and be stuck inside the positioning plate, which facilitates the reset of the ball and the sealing of the hole. When the device cools the material, the cooling airflow will flow along the cavity formed between the ball and the positioning plate after being ejected from the hole, so that the airflow will flow in multiple directions, increasing the distribution range of the cooling airflow in the tank.

[0010] Preferably, a cooling chamber is fixed to the outer wall of the tank; a pair of water pipes are connected to the middle of the cooling chamber; when cooling the material, a water pump can be connected to one end of the water pipe to allow cooling water to enter the interior of the cooling chamber. This cooling water will absorb the heat released by the material in the tank through heat exchange, thereby improving the cooling effect of the device on the material. At the same time, the cooled wastewater can be extracted through another water pipe, and the wastewater can be purified, cooled and recycled again. It will not be elaborated here. It is worth mentioning that because the valve is a mature existing technology, the valve at the water pipe is not shown in the figure.

[0011] Preferably, the cooling cavity is provided with insulation cotton on the outside; the tank is located inside the insulation cotton; by providing insulation cotton, because the insulation cotton has low thermal conductivity, the heat exchange between the outside and the cooling water in the cooling cavity will be suppressed, reducing the interference of the external environment on the heat exchange between the cooling cavity and the tank.

[0012] Preferably, the motor is provided with a baffle; the baffle and the bracket are fixedly connected; the surface of the baffle is perforated; by providing the baffle, some splashed liquid caused by mixing in the tank will be blocked when it falls onto the surface of the motor, reducing the contamination of the motor surface. At the same time, the holes on the surface of the baffle facilitate heat exchange between the motor and the outside.

[0013] The advantages of this utility model are:

[0014] 1.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figures 1 to 5As shown in the figure, the kaolin green and environmentally friendly bleaching device of this utility model includes a tank 1, a first feed inlet 12 at the top of the tank 1, a second feed inlet 13 at the top of the tank 1, a discharge pipe 111 connected to the bottom of the tank 1, a bracket 14 fixedly connected to the top of the tank 1, a motor 15 mounted on the top of the bracket 14, a rotating shaft 16 rotatably connected through the middle of the bracket 14, a belt sleeved between the rotating shaft 16 and the motor 15, and multiple sets of stirring blades 110 fixedly connected to the middle of the rotating shaft 16. An air inlet pipe 17 is connected to the top; the air inlet pipe 17 and the rotating shaft 16 are rotatably connected; a connecting ring 18 is fixedly connected to the middle of the rotating shaft 16; the rotating shaft 16 and the connecting ring 18 are connected; multiple air outlet pipes 19 are connected to the middle of the connecting ring 18; multiple holes are opened on the inner wall of the air outlet pipes 19; during operation, kaolin can be added into the tank 1 through the first feed port 12, and bleach can be added into the tank 1 through the second feed port 13. Then, the motor 15 is started, causing the rotating shaft 16 to rotate under the transmission of the belt. The rotating shaft 16 will drive the stirring blade 110 to enter the tank. The rotating shaft 16 allows the stirring blades 110 to stir and mix the materials inside the tank 1. During the reaction, the materials inside the tank 1 generate heat. At this time, the air inlet pipe 17 can be connected to a cooler via a pipe, allowing cooling airflow to enter the rotating shaft 16 through the air inlet pipe 17. The airflow flows from the holes in the inner wall of the rotating shaft 16 through the connecting ring 18 into the air outlet pipe 19. Finally, the airflow is ejected from the holes in the inner wall of the air outlet pipe 19, cooling the materials inside the tank 1 at different depths. The air outlet pipe 19 rotates with the rotating shaft 16, allowing the device to cool the materials at different depths and different temperatures inside the tank 1. Cooling occurs in the same direction, and the centrifugal force of the stirring blades 110 causes the material to continuously move closer to the air outlet pipe 19, increasing the contact area between the airflow and the material. Finally, the mixed material can be discharged by opening the valve of the discharge pipe 111. It is worth mentioning that, since the valve is a mature existing technology, the valves of the first feed port 12 and the second feed port 13 are not shown in the figure. Through the connection between the air inlet pipe 17 and the air outlet pipe 19, the cooling airflow can uniformly cool the material inside the tank 1, improving the cooling effect of the device on the material and also improving the bleaching effect of the device on kaolin.

[0026] Please see Figure 5As shown, multiple elastic ropes 2 are fixedly connected inside the air outlet pipe 19; a sphere 22 is fixedly connected to the end of each elastic rope 2; the sphere 22 and the hole are correspondingly arranged; by setting the elastic ropes 2 and the sphere 22, when the air cooler is not started, the sphere 22 will seal the hole under the elastic force of the elastic rope 2. When the material needs to be cooled, the cooling airflow will rush into the air outlet pipe 19, increasing the air pressure. The sphere 22 will be pushed out under the air pressure, allowing the airflow to spray out from the hole and cool the material; through the cooperation of the elastic ropes 2 and the sphere 22, the sphere 22 will seal the hole inside the air outlet pipe 19 under normal conditions, reducing the possibility of material entering the air outlet pipe 19 through the hole, thereby reducing the possibility of contamination inside the air outlet pipe 19.

[0027] Please see Figure 5 As shown, a positioning plate 3 is fixed to the inner wall of the hole; the inner wall of the positioning plate 3 has an arc-shaped structure; by setting the positioning plate 3, when the device stops cooling the material, the ball 22 will be reset under the elastic force of the elastic rope 2 and stuck into the interior of the positioning plate 3, which facilitates the reset of the ball 22 and the sealing of the hole. When the device cools the material, the cooling airflow will flow along the cavity formed between the ball 22 and the positioning plate 3 after being sprayed out from the hole, so that the airflow will flow in multiple directions, increasing the distribution range of the cooling airflow in the tank 1.

[0028] Please see Figure 2 As shown, a cooling chamber 4 is fixed to the outer wall of the tank 1; a pair of water pipes 42 are connected to the middle of the cooling chamber 4; when cooling the material, a water pump can be connected to one end of the water pipe 42 so that cooling water can enter the interior of the cooling chamber 4. This cooling water will absorb the heat released by the material in the tank 1 through heat exchange, thereby improving the cooling effect of the device on the material. At the same time, the wastewater after cooling can be extracted through the other water pipe 42. The wastewater can be purified and cooled and then recycled. It will not be described in detail here. It is worth mentioning that because the valve is a mature existing technology, the valve at the water pipe 42 in the figure is not shown.

[0029] Please see Figure 2 As shown, the cooling cavity 4 is provided with insulation cotton 5 on the outside; the tank 1 is located inside the insulation cotton 5; by providing insulation cotton 5, because insulation cotton 5 has low thermal conductivity, the heat exchange between the outside and the cooling water in the cooling cavity 4 will be suppressed, reducing the interference of the external environment on the heat exchange between the cooling cavity 4 and the tank 1.

[0030] Please see Figure 1 and Figure 2As shown, a baffle 6 is provided on the outside of the motor 15; the baffle 6 and the bracket 14 are fixedly connected; the surface of the baffle 6 is porous; by setting the baffle 6, when some splashed liquid caused by mixing in the tank 1 falls onto the surface of the motor 15, it will be blocked by the baffle 6, reducing the contamination of the surface of the motor 15. At the same time, the holes on the surface of the baffle 6 facilitate heat exchange between the motor 15 and the outside.

[0031] Working principle: Kaolin is added into tank 1 through the first feed port 12, and bleaching agent is added into tank 1 through the second feed port 13. Then, the motor 15 is started, causing the rotating shaft 16 to rotate under the drive of the belt. The rotating shaft 16 drives the stirring blade 110 to rotate, so that the stirring blade 110 can stir and mix the materials inside tank 1. The materials inside tank 1 generate heat during the reaction. At this time, the air inlet pipe 17 can be connected to a cooler through a pipe, so that the cooling airflow can enter the rotating shaft 16 through the air inlet pipe 17. The airflow will flow from the holes in the inner wall of the rotating shaft 16 through the connecting ring 18 into the air outlet pipe 19. Finally, the airflow will be sprayed out from the holes in the inner wall of the air outlet pipe 19 and spray the materials inside tank 1 from different depths. Cooling is achieved by rotating the exhaust pipe 19 along with the rotating shaft 16, allowing the device to cool the material at different depths and directions. Simultaneously, the centrifugal force of the stirring blades 110 causes the material to continuously move closer to the exhaust pipe 19, increasing the contact area between the airflow and the material. Finally, the mixed material can be discharged by opening the valve on the discharge pipe 111. It is worth noting that the valves are not shown in the diagram because they are existing, mature technology. By using the elastic rope 2 and the sphere 22, when the air cooler is not running, the sphere 22 seals the holes under the elastic force of the elastic rope 2. When cooling is needed, cooling airflow rushes into the exhaust pipe 19, increasing the air pressure. 2. Under air pressure, the ball 22 will be ejected, allowing airflow to spray out from the holes and cool the material. By setting a positioning plate 3, when the device stops cooling the material, the ball 22 will reset under the elastic force of the elastic rope 2 and lock into the interior of the positioning plate 3, facilitating the reset of the ball 22 and sealing the holes. When the device cools the material, the cooling airflow, after being ejected from the holes, will flow along the cavity formed between the ball 22 and the positioning plate 3, allowing the airflow to flow in multiple directions. During material cooling, a water pump can be connected to one end of a water pipe 42, allowing cooling water to enter the interior of the cooling chamber 4. This cooling water will absorb the heat released by the material in the tank 1 through heat exchange, improving the device's cooling efficiency. As a result, the cooled wastewater can be extracted through another water pipe 42. The wastewater can be purified, cooled, and recycled again, which will not be elaborated here. It is worth mentioning that because the valve is a mature existing technology, the valve at water pipe 42 is not shown in the figure. By setting up the insulation cotton 5, because the insulation cotton 5 has low thermal conductivity, the heat exchange between the outside and the cooling water in the cooling chamber 4 will be suppressed, reducing the interference of the external environment on the heat exchange between the cooling chamber 4 and the tank 1. By setting up the baffle 6, when some splashed liquid caused by mixing in the tank 1 falls onto the surface of the motor 15, it will be blocked by the baffle 6, reducing the contamination of the surface of the motor 15. At the same time, the baffle 6 has holes on its surface to facilitate the heat exchange between the motor 15 and the outside.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
