[0018] The following will be combined with the appendix Figures 1-2 The embodiments of the technical solution of this application are described in detail below. The following embodiments are only used to more clearly illustrate the technical solution of this application, and are therefore merely examples and should not be used to limit the scope of protection of this application. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] In view of the problems existing in the prior art, this application provides an AC high-level tank that facilitates the removal of impurities. Figure 1 A schematic diagram of the AC high-level tank structure is shown. Figure 2 It shows Figure 1 A cross-sectional view of the AC high-level tank. This embodiment provides an AC high-level tank for easy impurity removal, comprising: a tank cover 2 connected to the top of the tank body 1; a feed inlet 21 located at the top of the tank cover 2; a discharge outlet 22 located at the bottom of the tank body 1; a support leg 23 located at the bottom of the tank body 1; a filter device 3 connected inside the tank body 1; and a lifting device 4 connected to the filter device 3. The filter device 3 comprises a filter groove 31 with filter holes at the bottom and a connector located at the top of the filter groove 31; the filter groove 31 is cylindrical and vertically disposed inside the tank body 1; the filter groove 31 is snapped to the upper edge of the tank body 1 by the connector.

[0020] like Figures 1-2 As shown, in this embodiment, the tank body 1 serves as the main body, with a tank cover 2 connected to its top. A feed inlet 21 is provided at the top of the tank cover 2 for adding the production mother liquor generated during the production of ADC foaming agent. A discharge outlet 22 is provided at the lower end of the tank body 1 for collecting by-products after the production mother liquor is filtered, such as hydrochloric acid. Support legs 23 are installed at the bottom of the tank body 1 to provide necessary support and stability for the tank body 1.

[0021] In one implementation, the tank body 1 and the tank cover 2 are connected by a connecting flange.

[0022] Specifically, the flange connection between the tank body 1 and the tank cover 2 provides sufficient structural stability and sealing, effectively preventing leakage of by-products from the AC high-level tank and thus avoiding environmental pollution. Furthermore, the flange connection offers a simple installation and disassembly method, facilitating the installation and removal of the filter device 3 from the AC high-level tank under the control of the lifting device 4.

[0023] The filter device 3 is vertically installed inside the tank 1. This filter device 3 consists of a cylindrical filter tank 31 with filter holes at the bottom and a connector at the top. The diameter of the filter tank 31 is smaller than the diameter of the tank 1, and the height of the filter tank 31 is smaller than the height of the tank 1. This allows byproducts to flow out through the filter holes at the bottom of the filter tank 31 and be stored in the tank 1 for reuse when the filter tank 31 is vertically installed inside the tank 1. The filter tank 31 is secured to the upper edge of the tank 1 by the connector, ensuring stable positioning of the filter tank 31 and facilitating easy separation of the filter tank 31 from the tank 1. The connector can be a clamp, ring, or grooved connector, etc., not shown in the attached drawings.

[0024] The lifting device 4 is used to control the filter tank 31 to be lifted and removed from the tank body 1 after the filtration process is completed, so as to clean the filter tank 31 and replace the material, and to put the filter tank 31 back into the tank body 1 after cleaning.

[0025] In one implementation, the lifting device 4 includes a lift and a clamp disposed on the lift.

[0026] Specifically, the lift in the lifting device 4 can be electrically or pneumatically driven, with the appropriate load capacity selected based on the specific height of the AC high-level tank and the weight of the filter device 3. The lift is installed on one side or at the top of the tank 1. Optionally, the lift is equipped with an emergency stop button and an overload protection device to ensure operational safety.

[0027] The aforementioned clamps are customized according to the shape and size of the filter device 3 to ensure that the clamps can stably hold the filter device 3. Optionally, the clamps are designed to be adjustable to accommodate filter devices 3 of different sizes. Optionally, the clamps are equipped with a safety locking mechanism to prevent the filter device 3 from accidentally falling off during lifting.

[0028] The lifting device 4 provided in this embodiment not only improves the efficiency of replacing and cleaning the filter device 3, but also enhances the safety and convenience of the recycling operation.

[0029] Based on the previous embodiment, continue to refer to Figures 1-2 In one implementation, the filter device 3 further includes traction members 32 disposed on both sides of the filter tank 31, and the lifting device 4 is connected to the filter device 3 through the traction members 32 and pulls the filter device 3 to move longitudinally.

[0030] Specifically, balanced lifting control is achieved through traction components 32 located on both sides of the filter tank 31, ensuring the stability of the filter tank 31 during lifting and preventing equipment damage or safety accidents caused by uneven loading or instability. Optionally, the traction component 32 can be a lifting lug or a handle, and the traction component 32 is welded or bolted to the structural components of the filter tank 31 to ensure sufficient strength and stability.

[0031] In one implementation, the AC high-level tank further includes a condensing device connected to the filter device 3; the condensing device includes a condensing coil 41 coiled around the filter tank 31 and a first liquid inlet 42 and a first liquid outlet 43 disposed on the top of the tank cover 2.

[0032] Specifically, the design of the condenser coil 41 coiled around the outside of the filter tank 31 allows cooling media such as chilled water or refrigerant to pass through the inside of the coil, thereby absorbing heat from the outer wall of the filter tank 31. This causes volatile substances in the mother liquor to condense and then pass through the filter tank 31 to improve the purity of the recovered by-products. The first inlet 42 and the first outlet 43 are located on the top of the tank cover 2 for easy connection to an external cooling media supply system. The first inlet 43 allows cooling media to enter the condenser coil 41, while the first outlet 43 is used to discharge used cooling media.

[0033] In this embodiment, the condenser coil 41 is wound around the outer wall of the filter tank 31, which effectively utilizes the space between the tank body 1 of the AC high-level tank and the filter tank 31, reducing the operating cost of condensation recovery.

[0034] In one implementation, the tank 1 includes an inner tank 11 and an outer tank 12, with the outer tank 12 and the inner tank 11 forming a sealed cavity.

[0035] Specifically, the tank 1 consists of an inner tank 11 and an outer tank 12. This double-layer structure design enhances the overall structural stability of the tank. Furthermore, the sealed cavity reduces the impact of external temperature changes on the temperature of the material inside the tank 1, maintaining the material at a suitable temperature for reaction or storage. Optionally, the outer tank 12 and the inner tank 11 can be assembled together using flanges, welding, or bolt connections to ensure the sealing and stability of the connection.

[0036] Based on the previous embodiment, continue to refer to Figure 2 In one implementation, the AC high-level tank further includes a heat preservation device 5, which is disposed in the sealed cavity; the heat preservation device 5 includes a second liquid inlet 51 disposed above the side of the outer tank 12 and a second liquid outlet 52 disposed below the side of the outer tank 12.

[0037] Specifically, before starting the insulation process, the required insulation medium is injected through the second inlet 51. During the insulation process, the medium circulates within the sealed cavity, exchanging heat through the insulation material between the outer tank 12 and the inner tank 11. When it is necessary to replace the medium or stop the insulation process, the medium in the cavity is discharged through the second outlet 52.

[0038] This embodiment enhances the control of material temperature by installing a heat preservation device in the AC high-level tank, reduces the impact of external environmental temperature on by-product recycling, and effectively utilizes the structural layout of the AC high-level tank by setting the heat preservation device in the wall between the inner and outer tanks.
