Description

Technical Field

[0001] This utility model belongs to the field of raw material mixing equipment, specifically relating to a sodium selenite solution stirring tank. Background Technology

[0002] In the process of mixing sodium selenite solution, water and sodium selenite are usually mixed in a certain ratio and then pumped out. However, the current mixing method usually involves stirring the solution in a tank with a stirring blade. After mixing, the solution is pumped out by a water pump to the next process. This mixing method can indeed achieve a uniform mixing effect, but sodium selenite dissolves relatively quickly in water. It can still gradually dissolve by simply placing it in water and letting it stand. In other words, mixing sodium selenite by stirring with a motor-driven stirring blade will consume a lot of electrical energy to achieve a substance that is already easily soluble. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a sodium selenite solution mixing tank. By setting a three-way valve, water at the bottom of the tank is pumped upwards and enters the three-way valve. After the upper channel is blocked, the water flows in from the side of the tank. Under the pressure of the pump, the water flows at an angle into the inner cavity of the tank, forming a vortex-like water flow. The effect of circulating mixing is achieved by a single water pump, which saves energy. After mixing is completed, the left channel is blocked and the upper channel is opened, so that the water flows into the flow meter and then into the next process.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A sodium selenite solution stirring tank includes a tank body, a water pump, a three-way valve, and a flow meter. The lower end of the tank body is connected to the inlet of the water pump through a first connecting pipe. The outlet of the water pump is connected to the lower end of the three-way valve through a second connecting pipe. The left end of the three-way valve is connected to the side of the tank body through a third connecting pipe. The axis of the third connecting pipe does not intersect with the axis of the tank body. The connection between the third connecting pipe and the inner cavity of the tank body is tangent to the inner wall of the inner cavity of the tank body. The upper end of the three-way valve is connected to the flow meter through a fourth connecting pipe.

[0006] The tank body is also equipped with a premixing cylinder, which contains a premixing chamber. The premixing cylinder surrounds the connection between the third pipe and the inner cavity of the tank body. The third pipe communicates with the premixing chamber. The outer wall of the premixing cylinder is provided with several mixing holes that communicate with the premixing chamber. The mixing holes point towards the inner cavity of the tank body, and the axis of the mixing holes does not intersect with the axis of the tank body. The upper end face of the premixing cylinder is provided with an inlet that communicates with the premixing chamber. The premixing cylinder is also equipped with a mixing tank, which is located at the bottom of the premixing chamber. The mixing tank contains a mixing chamber, and the connection between the third pipe and the inner cavity of the tank body is located within the mixing chamber.

[0007] The sodium selenite solution mixing tank with this structure is used for adding sodium selenite raw materials and water. After addition, the mixture is pumped into the pump via the first pipe through the first pipe. The pump outlet then pumps the mixture into a three-way valve via the second pipe. The three-way valve is then set to be sealed at the top and open at the left. Therefore, the water flows into the third pipe after entering the three-way valve. To ensure the water entering the tank forms a unidirectional vortex under water pressure, the axis of the third pipe does not intersect with the axis of the tank. This allows the water flow to... When entering the tank, the water enters at a certain angle to the inner cavity of the tank, which can form a vortex under the drive of the water flow. However, in order to maximize the vortex state of the water flow, the connection between the third-way pipe and the inner cavity of the tank is tangent to the inner wall of the inner cavity of the tank. Therefore, the water flow entering the inner cavity of the tank will flow along the inner wall of the inner cavity of the tank, and the vortex formed is the fastest and has the best mixing effect. After the mixing is completed, the left end of the three-way valve is blocked and the upper end of the three-way valve is opened, so that the mixed water flow enters the flow meter under the pressure of the water pump. Before entering the next process, the output can be maintained by controlling the flow meter.

[0008] To achieve cyclical production, sodium selenite and water need to be added to the tank at regular intervals and in measured quantities. The volume of sodium selenite solution required is extremely large, necessitating rapid mixing without the need for additional stirring blades. However, the tank itself is too large; simply adding the raw materials and water for pump mixing could lead to the sodium selenite being pumped into the pump before it is fully dissolved, potentially burning out the pump. Therefore, when adding additional sodium selenite and water, pre-mixing is necessary through a fixed space before the pre-mixed mixture enters the tank. This prevents the large volume of raw materials from causing pump burnout. A pre-mixing cylinder is installed inside the tank, with a mixing trough at the bottom of the pre-mixing chamber. A third-party pipe connects to the mixing chamber within the mixing trough, which has an upward-opening, arc-shaped inner wall. As water flows in... When the water enters the mixing tank, it forms an upward spiral flow within the mixing chamber until it reaches the upper premixing chamber. The premixing cylinder has an inlet on its upper surface. Workers throw the sodium selenite raw material into the premixing cylinder from this inlet. Under gravity, the sodium selenite sinks to the bottom of the mixing tank, where the water undergoes initial mixing. The water then rises into the premixing chamber and flows into the tank through the mixing orifice. The axis of the mixing orifice does not intersect with the axis of the tank and points towards the inner wall of the tank. Therefore, the premixed water also forms a vortex within the tank through the mixing orifice, continuously mixing. Even if the sodium selenite raw material in the mixing tank is impacted into the premixing chamber by the water flow, it is not a problem, as the mixing orifice prevents large pieces of sodium selenite from flowing out. Therefore, the sodium selenite raw material can only be initially dissolved in the premixing cylinder before entering the tank for secondary mixing.

[0009] Furthermore, the upper opening of the tank body is covered with a tank lid, the upper surface of the tank lid is provided with a through hole corresponding to the feed inlet, and the upper surface of the tank lid is provided with a water inlet hole communicating with the inner cavity of the tank; a baffle is covered on the through hole, and the baffle is rotatably connected to the edge of the through hole.

[0010] Compared with the prior art, the advantages of this utility model are as follows: by placing sodium selenite raw material into the premixing cylinder for preliminary mixing, the design of the mixing hole can prevent large pieces of sodium selenite raw material from flowing into the tank and causing the water pump to burn out due to the intake of sodium selenite raw material. Sodium selenite raw material can only enter the tank for secondary mixing after preliminary dissolution in the premixing cylinder. The water flow entering the tank forms a vortex in the tank through the mixing hole, which has the best mixing effect and the fastest speed. It can achieve the purpose of mixing in the shortest time, avoids the use of stirring blades, and achieves the best mixing effect with minimal power consumption. Attached Figure Description

[0022] Description of the working principle of this utility model:

[0023] The sodium selenite solution mixing tank with this structure has a tank body 1 for adding sodium selenite raw material and water. After addition, the mixture at the bottom of the tank body 1 is drawn into the water pump 2 by starting the water pump 2. The outlet of the water pump 2 then pumps the mixture into the three-way valve 3 through the second-way pipe 6. At this time, the three-way valve 3 is set to be sealed at the top and open at the left. Therefore, the water flow enters the third-way pipe 7 after entering the three-way valve 3. In order to make the water flow entering the tank body 1 form a unidirectional vortex under its water pressure, the axis of the third-way pipe 7 does not intersect with the axis of the tank body 1, so that the water flow can form a vortex. When the water enters the tank 1, it enters at a certain angle to the inner cavity of the tank 1, which can form a vortex under the drive of the water flow. However, in order to maximize the vortex state of the water flow, the connection between the third pipe 7 and the inner cavity of the tank 1 is tangent to the inner wall of the inner cavity of the tank 1. Therefore, the water flow entering the inner cavity of the tank 1 will flow along the inner wall of the inner cavity of the tank 1, and the vortex formed is also the fastest and has the best mixing effect. After the mixing is completed, the left end of the three-way valve 3 is sealed and the upper end of the three-way valve 3 is opened, so that the mixed water flow enters the flow meter 4 under the pressure of the water pump 2. Before entering the next process, the output can be maintained by controlling the flow meter 4.

[0024] To achieve cyclical production, sodium selenite and water need to be added to tank 1 at regular intervals and in measured quantities. The amount of sodium selenite solution used is extremely large, requiring rapid mixing without the need for additional stirring blades. However, tank 1 itself is too large; simply adding the raw material and water for mixing with pump 2 could cause the sodium selenite to be pumped into pump 2 before it is fully dissolved, potentially burning out pump 2. Therefore, when adding additional sodium selenite and water, pre-mixing is necessary through a fixed space before the pre-mixed mixture is introduced into tank 1. This prevents the large volume of raw material from burning out pump 2. Therefore, a pre-mixing cylinder 11 is installed inside tank 1. The bottom of the pre-mixing chamber 111 within the pre-mixing cylinder 11 has a mixing trough 114. The connection between the third pipe 7 and the inner cavity of tank 1 is connected to the mixing chamber 115 within the mixing trough 114. The mixing trough 114 has an upward-opening, arc-shaped inner wall structure. Water flows into the mixing trough 114... At this time, the water flow forms an upward spiral flow in the mixing chamber 115 until it enters the upper premixing chamber 111. The upper end face of the premixing cylinder 11 is provided with a feed inlet 113. At this time, the operator throws the sodium selenite raw material into the premixing cylinder 11 from this point. Under the action of gravity, the sodium selenite raw material will sink to the bottom of the mixing tank 114. Therefore, the water flow will initially mix with the sodium selenite raw material here. After that, the water flow rises into the premixing chamber 111 and flows into the tank 1 through the mixing hole 112. The axis of the hole 112 does not intersect with the axis of the tank 1 and points towards the inner wall of the tank 1. Therefore, the premixed water flow can also form a vortex in the tank 1 through the mixing hole 112 and continue to mix. Even if the sodium selenite raw material in the mixing tank 114 is impacted into the premixing chamber 111 by the water flow, it is not a problem. The mixing hole 112 can prevent large pieces of sodium selenite raw material from flowing out. Therefore, the sodium selenite raw material can only enter the tank 1 for secondary mixing after being initially dissolved in the premixing cylinder 11.

[0025] To prevent pollutants from entering the tank 1, a tank cover 12 is installed at the upper opening of the tank 1 to prevent pollutants from entering. At the same time, a water inlet 122 is opened on the tank cover 12 for connecting to a water source. The through hole 121 corresponding to the feed inlet 113 is covered by a baffle 123. When feeding is required, the baffle is opened manually and the raw materials are thrown in.

[0026] The beneficial effects of this utility model are as follows: by placing sodium selenite raw material into the premixing cylinder 11 for preliminary mixing, the setting of the mixing hole 112 can prevent large pieces of sodium selenite raw material from flowing into the tank 1 and causing the water pump 2 to burn out due to the intake of sodium selenite raw material. The sodium selenite raw material can only enter the tank 1 for secondary mixing after being initially dissolved in the premixing cylinder 11. The water flow entering the tank 1 forms a vortex in the tank 1 through the mixing hole 112, which has the best mixing effect and the fastest speed. It can achieve the purpose of mixing in the shortest time, avoids the use of stirring blades, and achieves the best mixing effect with the least amount of electricity.
