Description

Technical Field

[0001] This utility model relates to the field of ATO dispersion preparation, and in particular to a high-efficiency antistatic ATO dispersion preparation device. Background Technology

[0002] The preparation of ATO involves a co-precipitation process, which requires pH control. Ammonia (NH3·H2O) or NaOH solution is used as the precipitant and added slowly (e.g., 1-2 mL / min) using a peristaltic pump or dropping funnel. This avoids localized over-alkaliness that could lead to asynchronous precipitation of Sn and Sb. Rapid addition would cause Sn(OH)4 and Sb(OH)3 to precipitate in steps, disrupting the uniformity of doping.

[0003] A search revealed patent publication number CN209985393U, which discloses a device for preparing nano-metal oxide dispersions. The device includes a sealed reaction tower, a crucible for holding the reaction liquid, a microwave heater, a tail gas exhaust mechanism, a powder transport pipe, a sand mill, and a reaction vessel. The sealed reaction tower houses the microwave heater, with the crucible positioned above it. The tail gas exhaust mechanism is connected to the sealed reaction tower, which is connected to the sand mill via the powder transport pipe. The sand mill is connected to the reaction vessel. This invention is energy-saving and environmentally friendly; the entire production process, from powder generation to dispersion output, is sealed, preventing impurities from entering; it employs a composite dispersion method, efficiently preparing nano-metal oxide dispersions with narrow particle size distribution and good repeatability, enabling continuous production and significantly improving production efficiency.

[0004] While existing technologies can achieve certain dispersion preparation effects, they suffer from drawbacks: the lack of efficient and complete reaction and rapid separation functions in existing dispersion preparation devices leads to slow dispersion preparation, incomplete reaction, impurities, and a series of other problems. In view of this, we propose a high-efficiency antistatic ATO dispersion preparation device that solves the above problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a highly efficient antistatic ATO dispersion preparation device.

[0006] The technical solution of this utility model is as follows: A high-efficiency antistatic ATO dispersion preparation device, comprising a box, a collection tank, a filter screen, and a bottom plate. The bottom plate is provided inside the box, and a filter screen is fixed at the upper end of the bottom plate. The rear half of the filter screen is designed to be curved upwards. Both the bottom plate and the filter screen have through holes on their surfaces. A lead screw is rotatably installed on one side of the inner wall of the box. The lead screw is threadedly connected to the filter screen and the bottom plate. A linear motor is fixed at the upper end of the box, and a groove is provided on one side of the linear motor. A push plate is provided inside the box, and a collection tank is fixed on one side of the linear motor. A nozzle is provided at the lower end of the collection tank, penetrating the upper surface of the box.

[0007] In use, the base liquid and reaction liquid for ATO dispersion preparation are introduced into the tank and collection tank respectively. The base liquid is continuously stirred under the drive of a rotating motor, and the reaction liquid is dripped from the nozzle at the bottom of the collection tank using a flow valve. After the reaction liquid comes into contact with the base liquid, a precipitate is formed. At regular intervals, a servo motor drives a lead screw to move the bottom plate and filter screen upwards. When the filter screen moves to the bottom of the push plate, a linear motor drives the push plate to push the precipitate out of the outlet for collection, and then proceeds to the next processing step. This device has the function of efficient and complete reaction and separation of precipitate, and can accurately control the specific gravity of reactants by drip irrigation to achieve precise preparation of dispersion.

[0008] Preferably, a bracket is fixed to the lower end of the housing, a base is fixed to the lower end of the bracket, a control panel is fixed to one side of the outer wall of the housing, and a discharge port is provided on one side of the outer wall of the housing. The bracket and the base provide rigid support to ensure the accuracy of the screw lifting and the push plate movement.

[0009] Preferably, a feed pipe is provided on one side of the lower end of the tank, and a discharge pipe is provided on one side of the feed pipe. The feed pipe enables continuous replenishment of the bottom liquid and the reaction liquid, and the discharge pipe, in conjunction with the push plate, quickly discharges the precipitate, reducing manual intervention and improving process efficiency.

[0010] Preferably, the linear motor has an output end on one side and a connecting frame is fixed on one side of the output end. A push plate is fixed at the lower end of the connecting frame. One side of the push plate is designed with an arc shape. The arc edge of the push plate fits the curved surface of the filter screen to ensure that the sediment is completely pushed out and reduce material loss.

[0011] Preferably, a servo motor is provided at the upper end of the housing, the output shaft of the servo motor is fixedly connected to the lower end of the lead screw, and a limiting rod is provided at the four corners inside the housing, the limiting rod being inserted into the bottom plate and the filter screen.

[0012] Preferably, a monitor is embedded in the outer wall of one side of the housing, and a flow valve is provided at the lower end of the nozzle. The monitor displays the acceleration of the reaction droplets and the precipitation state in real time, and the flow valve dynamically adjusts the flow rate according to the feedback to ensure that the stoichiometric ratio of the reaction liquid to the base liquid is accurate and controllable.

[0013] Preferably, a stirring rack is provided at the lower end of the box body, and a rotating motor is fixed at the lower end of the box body. The output shaft of the rotating motor is fixedly connected to the rotation center of the lower end of the stirring rack.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model achieves dropwise addition of the reaction solution to the base liquid through the cooperation of the nozzle and the flow valve, simulating the slow dropwise addition operation in the laboratory, avoiding asynchronous precipitation caused by local over-alkaliness, ensuring uniform co-precipitation of Sn and Sb, and meeting the requirements for fine pH control in the co-precipitation method.

[0016] Second, based on the first beneficial effect, the screw drives the lifting and lowering of the filter screen and the bottom plate, combined with the pusher plate to push out the precipitate, realizing continuous operation of reaction and separation, reducing the residence time of particles in the reaction system and inhibiting agglomeration; the through holes of the bottom plate and the filter screen, combined with the stirring rack, promote the uniform flow of the reaction liquid, avoid the accumulation of precipitate, and improve the mass transfer efficiency.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
