DETAILED DESCRIPTION

[0027] The following will be described in detail with reference to the accompanying drawings. Figures 1-3 The present application will be further described in detail.

[0028] The present application discloses an MBT reaction kettle electromagnetic heating device.

When the inductive coil 2 is electrified, heat can be generated in the reaction kettle 1 by using the principle of electromagnetic induction, so as to realize the heating of the solution inside the reaction kettle 1. The inductive coil 2 is formed by winding long wires in the direction of a spiral line, and the long wires are wrapped with a flexible protective sleeve (not shown in the figure), and the flexible protective sleeve is a woven belt wrapped outside the long wires in the present embodiment.

[0032] Referring to Figure 2 and Figure 3 , the first heat preservation member 3 includes a fixed layer 32 and a heat preservation layer 31. The heat preservation layer 31 is made of heat preservation cotton, which is wrapped outside the reaction tank 1 to achieve heat preservation of the reaction tank 1. The fixed layer 32 is in the form of a one-side open shell structure, which is arranged outside the heat preservation cotton, so as to fix the heat preservation cotton and block the falling of the heat preservation cotton. In the embodiment, the fixed layer 32 is a woven bag formed by polyethylene weaving. After being arranged outside the heat preservation layer 31, the fixed layer 32 can adapt to the irregular shape of the outside lateral wall of the heat preservation cotton after being wrapped. Meanwhile, the fixed layer 32 can be folded, which is convenient for storage when idle. The thickness of the heat preservation layer 31 is not less than 20 cm, and in the embodiment, the thickness of the heat preservation layer 31 is 25 cm.

[0033] Referring to Figure 2 and Figure 3 , the fixed layer 32 is provided with a binding belt 4 outside, which is tied near the ground outside the fixed layer 32, so as to fix the fixed layer 32 and improve the stability of the first heat preservation member 3 during use. In the embodiment, the binding belt 4 is a metal wire. The reaction tank 1 is provided with a supporting column 6 on one side, and the supporting column 6 is fixed to the ground. The binding belt 4 and the supporting column 6 are provided with a pulling rope 5 therebetween, one end of the pulling rope 5 is tied to the metal wire, and the other end is tied to the supporting column 6, so as to block the downward movement of the binding belt 4 and the falling of the fixed layer 32. A plurality of supporting columns 6 are uniformly and spacedly arranged along the circumference of the reaction tank 1, and a plurality of pulling ropes 5 are correspondingly arranged, so as to further reduce the downward sliding of the binding belt 4.

[0034] Referring to Figure 2 and Figure 3The surrounding plate 11 is arranged between the adjacent supporting columns 6, the surrounding plate 11 is horizontally arranged, and the side of the surrounding plate 11 close to the reaction tank 1 is in abutment with the reaction tank 1, so that the reaction tank 1 can be limited, the stability of the reaction tank 1 during use is improved, and the risk of the reaction tank 1 being tilted is reduced.

[0035] With reference to Figure 2 and Figure 3 The mounting piece 7 is arranged on the supporting column 6, the mounting piece 7 comprises a vertical plate and a horizontal plate, the vertical plate is vertically arranged, the horizontal plate is horizontally arranged, the vertical plate is vertically welded on the side of the horizontal plate away from the supporting column 6, and an L-shaped structure is formed. The vertical plate is located above the horizontal plate, and a slot is formed between the vertical plate and the supporting column 6. The surrounding plate 11 is inserted into the slot in the vertically downward direction, so as to realize the connection between the surrounding plate 11 and the supporting column 6.

[0036] With reference to Figure 2 and Figure 3 The pulling piece 8 is arranged between the induction coil 2 and the bundling belt 4, and the pulling piece 8 is in a flexible belt structure. The induction coil 2 is fixedly connected with the pulling piece 8. One end of the pulling piece 8 away from the ground is connected with the bundling belt 4, so as to block the downward movement of the induction coil 2 and improve the stability of the induction coil 2 during use. Specifically, one end of the belt structure of the pulling piece 8 is bound on a circle of wires close to the ground of the induction coil 2, then extends upward, and is wound outside the adjacent circle of wires. After bundling, the pulling piece 8 continues to extend upward to be wound on the wires again and is bound, and then continues to extend upward. In this way, the multiple circles of wires are bound and fixed at equal distances. After the pulling piece 8 is wound and bound, multiple fixed rings 82 corresponding to the pitch of the induction coil 2 are formed at the positions of the wires. In fact, the pulling piece 8 can also be understood as a fixing structure composed of a vertical belt 81 and the fixed rings 82. The fixed rings 82 are arranged on the vertical belt 81 in the vertical direction, and the wires of the induction coil 2 are arranged in the fixed rings 82.

[0040] The implementation principle of the MBT reaction tank 1 electromagnetic heating device is as follows: the reaction tank 1 is made of a conductor material, and when the induction coil 2 arranged outside the reaction tank 1 is powered, the reaction tank 1 can generate heat, thereby realizing the heating of the inside of the reaction tank 1. The capacity of the heating device on the reaction tank 1 is reduced, and the contact between the heating device and the chemical agent is reduced, thereby prolonging the service life of the heating device and improving the stability of the reaction tank 1 during use.
