Description

Technical Field

[0001] This utility model belongs to the field of slurry mixing equipment, and specifically relates to a mixing tank for reducing foam in slurry. Background Technology

[0002] During the slurry mixing process, the flow of materials and the interactions between different slurries can easily lead to the generation of numerous air bubbles. The presence of these bubbles can cause multiple quality problems: First, the oxygen in the bubbles reacts with the sugars in the slurry via a Maillard reaction, causing the product to darken and brown, deteriorate in flavor, and develop a burnt taste. It can also cause functional components such as vitamins and flavorings to become ineffective due to oxidation. Second, the oxygen-rich environment created by the bubbles promotes the growth of aerobic microorganisms such as molds and yeasts, thus affecting product stability and significantly shortening shelf life. Furthermore, bubbles can also lead to uneven mixing and measurement errors, impacting the quality of the final product. Utility Model Content

[0003] The purpose of this invention is to provide a mixing tank that reduces foam in slurry, thereby solving the problem of a large number of air bubbles in the slurry.

[0004] To address the aforementioned technical problems, this utility model provides a mixing tank for reducing foam in slurry, comprising a slurry mixing tank body, a pipe through-hole at the top of the slurry mixing tank body, a pipe connection fixedly connected to the pipe through-hole, a stirring tube rotating bearing disposed in the middle of the pipe connection, a slurry stirring tube fixedly connected to the inner side of the stirring tube rotating bearing, one end of the slurry stirring tube fixedly connected to the stirring tube rotating bearing, and the other end of the slurry stirring tube disposed inside the slurry mixing tank body, the slurry stirring tube being curved, and used to stir the slurry in the slurry mixing tank body; a slurry input pipe is also inserted into one end of the slurry stirring tube connected to the pipe connection, the slurry input pipe being used to input slurry into the slurry mixing tank body, a slurry output component is also disposed on the slurry mixing tank body, and a power component is connected to the slurry stirring tube.

[0005] Furthermore, the slurry mixing pipe includes a straight mixing pipe and a bent mixing pipe, the bent mixing pipe being curved and used for mixing the slurry.

[0006] Furthermore, the slurry input pipe extends within the mixing straight pipe to the connection point between the mixing straight pipe and the mixing bend.

[0007] Furthermore, a sealing ring is provided above the rotating bearing of the mixing tube at the pipe connection part. The outer side of the sealing ring is tightly connected to the pipe connection part, and the inner side of the sealing ring is tightly connected to the slurry input pipe.

[0008] Furthermore, the power assembly includes a rotary motor, which is fixed to the top of the outside of the slurry mixing tank. The motor shaft of the rotary motor is fixedly connected to a gear, and a gear ring is provided on the outside of the stirring tube. The gear is used to cooperate with the gear ring to drive the stirring tube to rotate through the rotation of the motor shaft of the rotary motor.

[0009] Furthermore, an exhaust channel is provided at the top of the slurry mixing tank, and a pressure valve is provided outside the slurry mixing tank for the exhaust channel.

[0012] The beneficial effects of this invention's mixing tank for reducing foam in slurry are as follows: The mixing tank body has a pipe through-hole at its top, with a pipe connector fixedly connected to the through-hole. A stirring tube bearing is located in the middle of the pipe connector, and a slurry stirring tube is fixedly connected to the inner side of the stirring tube bearing. The stirring tube is curved. When the stirring tube rotates, the curved shape forces the added slurry and the existing slurry in the mixing tank to be sprayed or thrown onto the tank wall and squeezed against each other. Furthermore, during the stirring process, most air bubbles are broken, thus reducing the amount of air bubbles in the slurry. Attached Figure Description

[0014] To better understand the purpose, structure, and function of this utility model, the following description is in conjunction with the appendix. Figure 1 The present invention provides a more detailed description of a mixing tank for reducing foam in slurry.

[0015] like Figure 1As shown, a mixing tank for reducing foam in slurry according to an embodiment of the present invention includes a slurry mixing tank body 100. A pipe through-hole is provided at the top of the slurry mixing tank body 100, and a pipe connection part 200 is fixedly connected to the pipe through-hole. A stirring tube rotating bearing 300 is provided in the middle of the pipe connection part 200, and a slurry stirring tube 400 is fixedly connected to the inner side of the stirring tube rotating bearing 300. One end of the slurry stirring tube 400 is fixedly connected to the stirring tube rotating bearing 300. The other end is located inside the slurry mixing tank 100. The slurry stirring pipe 400 is curved and is used to stir the slurry in the slurry mixing tank 100. One end of the slurry stirring pipe 400 is connected to the pipe connection 200 and a slurry input pipe 500 is also inserted. The slurry input pipe 500 is used to input slurry into the slurry mixing tank 100. The slurry mixing tank 100 is also equipped with a slurry output component 600, and the slurry stirring pipe 400 is connected to a power component.

[0016] In use, the slurry inlet pipe 500 delivers slurry into the slurry mixing tank 100 via the slurry stirring pipe 400. As the stirring pipe 400 rotates, its curved shape causes the slurry to flow along its end into the mixing tank 100. Some of this slurry impacts the inner wall of the mixing tank 100, where it is thinned and circulated, thus bursting some air bubbles. Other slurry impacts existing slurry within the mixing tank 100, causing some air bubbles to burst. Finally, existing slurry within the mixing tank 100 is compressed by the stirring pipe 400, further bursting some bubbles. Through the combined effect of these factors, most air bubbles in the slurry burst, achieving the goal of reducing air bubbles in the slurry.

[0017] In this utility model, the slurry mixing pipe 400 includes a straight mixing pipe 410 and a bent mixing pipe 420. The bent mixing pipe 420 is bent and is used to mix the slurry.

[0018] In order to allow the slurry in the slurry input pipe 500 to enter the slurry mixing tank 100 more quickly and to reduce the impact of slurry backflow on the rotating bearing 300 of the stirring tube or the pipe connection 200, the slurry input pipe 500 can be understood to extend in the stirring straight pipe 410 to the connection between the stirring straight pipe 410 and the stirring bend 420.

[0019] A sealing ring 310 is provided above the rotating bearing 300 of the stirring tube at the pipe connection 200. The outer side of the sealing ring 310 is tightly connected to the pipe connection 200, and the inner side of the sealing ring 310 is tightly connected to the slurry input pipe 500. The sealing ring 310 increases the airtightness of the slurry mixing tank 100, preventing gas in the slurry mixing tank 100 from overflowing from the pipe connection 200 and causing environmental pollution.

[0020] In this invention, the power assembly includes a rotary motor 910, which is fixed to the top of the outer side of the slurry mixing tank 100. A gear 920 is fixedly connected to the motor shaft of the rotary motor 910. A stirring tube gear ring 411 is provided on the outer side of the stirring straight tube 410. The gear 920 engages with the stirring tube gear ring 411 to drive the stirring straight tube 410 to rotate via the rotation of the motor shaft of the rotary motor 910. When it is necessary to rotate the slurry stirring tube 400, the rotary motor 910 is started. The motor shaft of the rotary motor 910 drives the gear 920 to rotate. The gear 920 engages with the stirring tube gear ring 411, converting the rotation of the gear 920 perpendicular to the horizontal plane into the rotation of the stirring tube gear ring 411 on the horizontal plane, thereby driving the stirring straight tube 410 to rotate, causing the stirring curved tube 420 to rotate, thus realizing the rotation of the slurry stirring tube 400. The rotary motor 910 is located outside the slurry mixing tank 100.

[0021] To prevent the slurry mixing tank 100 from becoming too pressurized and posing a danger, an exhaust channel 700 is provided at the top of the slurry mixing tank 100. A pressure valve 710 is installed outside the exhaust channel 700. When the internal gas pressure of the slurry mixing tank 100 exceeds the preset pressure of the pressure valve 710, the pressure valve 710 opens, allowing the gas inside the slurry mixing tank 100 to be discharged to a designated location through the exhaust channel 700.

[0022] Understandably, a level sensor 720 is installed inside the slurry mixing tank 100. The level sensor 720 is electrically connected to the control unit 800, which is located outside the slurry mixing tank 100 and electrically connected to the pressure valve 710. This design allows the operator to adjust the timing of gas release by the pressure valve 710 according to specific circumstances. When the level sensor 720 reaches a preset value, it transmits a signal to the control unit 800, which then sends an opening signal to the pressure valve 710, causing the pressure valve 710 to open and release gas. When the pressure valve 710 does not receive a release signal, it will also release gas when the gas pressure reaches a preset value to maintain the safety of the slurry mixing tank 100.

[0023] In some embodiments, a spiral section 110 is provided on the inner wall of the slurry mixing tank 100 for slurry flow. When the slurry is located on the inner wall of the slurry mixing tank 100, due to the spiral section 110, the slurry will not spread out, but will concentrate in the groove of the spiral section 110, reducing the contact area between the slurry and air and reducing the possibility of air bubbles being generated again. The slurry in the groove of the spiral section 110 will return to the slurry stored in the slurry mixing tank 100 under the influence of gravity.

[0024] If it is necessary to output the slurry from the slurry mixing tank 100, the slurry in the slurry mixing tank 100 can be output to the subsequent process through the slurry output component 600.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
