Description

Technical Field

[0001] This utility model relates to the field of alumina production technology, and specifically to a TCA synthesis tank. Background Technology

[0002] The current production capacity of alumina is limited by the flow rate of leaf filters, which are used for secondary separation. The filter cloth and tricalcium aluminate (TCA) work together to trap solids (silicon in sodium aluminate solution) in the crude liquid. TCA is a filter medium (also known as a filter aid), and the reaction time and quality instability of the filter aid directly affect the filtration effect.

[0003] In order to reduce the amount of lime required for TCA synthesis, our company designed a mixing tank upstream of the TCA coarse synthesis tank. This tank is used to ensure that the concentrate in the concentrate tank of the alumina production line is in full contact with the lime in the lime slurry tank. For specific technical solutions, please refer to CN218872162U (a TCA synthesis tank for an alumina production line).

[0004] When implementing the technical solution in the application, it was found that the concentrate and lime entering the mixing tank simply mixed naturally, resulting in poor mixing efficiency. The length of the mixing tank needed to be increased to meet the mixing requirements, but the existing space in the production workshop could not meet the equipment length requirements. Utility Model Content

[0005] To address the problem that increasing the length of the mixing tank to achieve the desired mixing effect results in a large space requirement in practical applications, this invention provides a TCA synthesis tank. By shortening the length of the mixing tank and installing a vibration component on the mixing tank, the mixing effect is improved through the shaking of the mixing tank, thereby reducing the space requirement in practical applications.

[0006] The technical solution of this utility model is:

[0007] A TCA synthesis tank, comprising:

[0008] The tank has a feed inlet at the top and a discharge outlet at the bottom.

[0009] A mixing tank is located upstream of the tank body. The outlet of the mixing tank is connected to the inlet of the tank body, and the raw materials to be mixed are connected to the inlet of the mixing tank.

[0010] The mixing tank includes a tank body and a vibration assembly mounted on the tank body.

[0011] Optionally, one end of the box body is the outlet of the mixing box, and the top opening at the other end of the box body is the inlet of the mixing box.

[0012] Optionally, multiple baffles are provided on the bottom surface of the box.

[0013] Optionally, all of the baffles are V-shaped structures, with the included angle between the two ends of the baffle being less than 160° and greater than 120°.

[0014] Optionally, the box is placed in an inclined direction, all the baffles are arranged with their corners facing upwards, and a plurality of protrusions are provided on the upward-facing side of the baffles.

[0015] Optionally, it also includes a frame, on which the housing is slidably mounted;

[0016] The vibration assembly includes:

[0017] The motor has its output shaft connected to the housing and is used to drive the housing to slide back and forth.

[0018] The drive unit is located between the output shaft of the motor and the housing.

[0019] Optionally, the driving unit includes:

[0020] A drive wheel is rotatably located on the side of the housing;

[0021] A drive component is disposed on the output shaft of the motor. The surface of the drive component has multiple protrusions that can contact the wheel surface of the drive wheel.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] The mixing material is fed into the mixing tank through the inlet. During the mixing process, the mixing tank is shaken by the vibration component, which causes the mixing material inside the mixing tank to move irregularly, thereby improving the mixing effect. This can significantly shorten the length of the mixing tank and reduce the space requirements in actual applications. Attached Figure Description

[0033] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0034] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0035] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0036] Example:

[0037] See Figure 1 , Figure 2 and Figure 3 This embodiment discloses a TCA synthesis tank, including a tank body 10 and a mixing tank 20. The tank body 10 is a crude TCA synthesis tank, and a secondary TCA synthesis tank 30 is located downstream of the tank body 10. The mixing tank 20 is located upstream of the tank body 10, and is used to mix the raw materials (semen from the semen tank and lime from the lime slurry tank) entering the tank body 10.

[0038] Specifically, the tank 10 has a feed inlet at the top and a discharge outlet at the bottom. The feed inlet of the tank 10 is connected to the discharge outlet of the mixing tank 20, and the discharge outlet of the tank 10 is connected to the feed inlet of the secondary synthesis tank 30. The bottom of one end of the mixing tank 20 is its discharge outlet, and the top of the other end of the mixing tank 20 is its feed inlet. Mixed raw materials are fed into the mixing tank 20 from its feed inlet.

[0039] See Figure 2 and Figure 3 The mixing tank 20 includes a vibration component 22 on the tank body 21. During the mixing process, the vibration component 22 shakes the mixing tank 20, causing the raw materials inside the mixing tank 20 to move irregularly, thereby improving the mixing effect and significantly shortening the length of the mixing tank 20, thus reducing the space requirements in practical applications.

[0040] In one specific embodiment:

[0041] See Figure 4 and Figure 5 Multiple baffles 23 are provided on the bottom surface of the inner side of the box 21. After the mixed raw material enters the box 21, the baffles 23 block the mixed raw material, thereby causing the mixed raw material to have an impact effect at the baffles 23. Combined with the shaking effect of the box 21 by the vibration component 22, the mixed raw material is pushed upward by the baffles 23, thereby enhancing the mixing effect of the mixed raw material.

[0042] Preferably, such as Figure 5 As shown, all baffles 23 have a V-shaped structure, with the included angle between the two ends of the baffle 23 being less than 160° and greater than 120°. Furthermore, along the length of the box 21, adjacent rows of baffles 23 are staggered.

[0043] In this embodiment, by setting the baffle 23 to a V-shape, lime can be prevented from depositing at the connection between the baffle 23 and the bottom surface of the box 21.

[0044] In another specific embodiment:

[0045] The housing 21 is placed at an angle, with all the baffles 23 facing upwards at their corners. Multiple protrusions 24 are provided on the upward-facing side of each baffle 23. By providing protrusions 24 on the baffles 23, the mixing material on the surface of the baffles 23 is blocked, and tiny eddies are generated on the surface of the baffles 23, thereby improving the mixing effect.

[0046] In another specific embodiment:

[0047] The TCA synthesis tank also includes a frame (not shown in the figure), on which the aforementioned housing 21 is slidably mounted.

[0048] The aforementioned vibration assembly 22 includes a motor 22-1 and a drive unit. The motor 22-1 is fixedly mounted on the frame, and the drive unit is mounted on the output shaft of the motor 22-1. The drive unit is connected to the housing 21 and directly drives the housing 21 to slide back and forth on the frame through the motor 22-1 and the drive unit.

[0049] Specifically, the drive unit includes a drive wheel 22-2 and a drive component 22-3. The drive wheel 22-2 is rotatably mounted on the side of the housing 21, and its axis is perpendicular to the length direction of the housing 21. The drive component 22-3 is mounted on the output shaft of the motor 22-1 and rotates with the output shaft of the motor 22-1. Multiple protrusions 24 are circumferentially arranged on the outer surface of the drive component 22-3, and all protrusions 24 can contact the wheel surface of the drive wheel 22-2.

[0050] During operation, the motor 22-1 drives the drive component 22-3 to rotate, and all the protrusions 24 on the drive component 22-3 contact the drive wheel 22-2 one by one, thereby pushing the drive wheel 22-2 through the drive component 22-3, and pushing the housing 21 to slide on the frame through the drive wheel 22-2.

[0051] Preferably, vibration components 22 are symmetrically arranged on both sides of the housing 21, and the motors 22-1 in the two drive components move synchronously. The two drive components 22-3 are installed in the same way, and the protrusions 24 on the two drive components 22-3 are set one-to-one. This design ensures the stability of the housing 21 on the frame.

[0052] In another specific embodiment:

[0053] Multiple tracks 25 are provided on both sides of the housing 21, and support blocks 26 that slide and match the tracks 25 are provided on the frame. The tracks 25 are set along the inclined direction.

[0054] In this embodiment, the support block 26 provided on the frame provides support for the housing 21, and the sliding path of the housing 21 is restricted by the sliding match between the support block 26 and the track 25.

[0055] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
