Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to a device for preparing an aminosulfonic acid cleaning agent. Background Technology

[0002] Aminosulfonic acid cleaning agents, as highly efficient industrial cleaning materials, are widely used to remove oxide scale, rust, and other dirt from metal surfaces. Their preparation process typically requires precise control of parameters such as the mixing ratio of raw materials, temperature, and stirring speed to ensure the performance and quality of the final product. Traditional aminosulfonic acid cleaning agent preparation equipment has several shortcomings in actual operation, such as uneven raw material addition, poor stirring effect, and low cleaning agent filtration efficiency. These problems not only affect product quality but may also lead to low production efficiency.

[0003] Existing aminosulfonic acid cleaning agent preparation devices mainly consist of a simple tank, stirring mechanism, and feeding system. However, these devices often lack effective design for key aspects such as raw material buffering, uniform feeding, auxiliary agent dispersion, and cleaning agent filtration. Specifically:

[0004] In existing preparation equipment, aminosulfonic acid raw materials are directly added into the tank without an effective buffering mechanism. This may result in a large amount of raw materials being added at once, causing excessively high local concentrations and affecting product quality.

[0005] The addition of additives is usually done by directly introducing them into the tank through a pipe. This method can easily lead to uneven distribution of the additives, affecting the final effect of the aminosulfonic acid cleaning agent.

[0006] If the cleaning agent is discharged without filtration or with low filtration efficiency after preparation, it may contain undissolved raw material particles or impurities, reducing the purity of the cleaning agent and affecting its effectiveness.

[0007] Therefore, there is an urgent need for an improved aminosulfonic acid cleaning agent preparation device that can provide more efficient raw material management, more uniform additive dispersion, more thorough mixing, and more efficient cleaning agent filtration, thereby improving the quality and production efficiency of aminosulfonic acid cleaning agents. Summary of the Invention

[0008] The technical problem to be solved by this utility model is to provide a preparation device for aminosulfonic acid cleaning agent. By introducing an aminosulfonic acid raw material buffer tank, an optimized auxiliary agent distribution tray and a high-efficiency filtration mechanism, the preparation process level of aminosulfonic acid cleaning agent is significantly improved.

[0009] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a preparation device for aminosulfonic acid cleaning agent, including a tank body, an aminosulfonic acid raw material buffer tank is provided near the top of the tank body, a feeding pipe is provided at the top of the aminosulfonic acid raw material buffer tank, a discharge pipe is provided at the bottom of the tank body, a motor is provided at the top of the tank body, a rotating shaft is provided inside the aminosulfonic acid raw material buffer tank, the rotating shaft passes downward through the discharge pipe and extends to the bottom of the tank body, a spiral feeding blade is provided on the rotating shaft part located in the discharge pipe, and a stirring blade is provided on the rotating shaft part located inside the tank body.

[0010] In a preferred embodiment, the tank sidewall is provided with an additive inlet pipe and a water inlet pipe.

[0011] In a preferred embodiment, the tank body is further provided with an additive distribution tray, which is set in an annular groove on the inner wall of the tank body. The additive distribution tray has an annular groove and an additive output hole in the annular groove. The output end of the additive inlet pipe is located directly above the groove of the additive distribution tray.

[0012] In a preferred embodiment, the additive distribution disc is located below the discharge pipe and above the stirring blades. The additive distribution disc has a ring structure, and the inner circular wall of the additive distribution disc is connected and fixed to the rotating shaft by a connecting rod.

[0013] In a preferred embodiment, the bottom of the tank is provided with a cleaning agent outlet pipe, the cleaning agent outlet pipe is provided with a cleaning agent output valve, and a filter mechanism is provided inside the cleaning agent outlet pipe below the cleaning agent output valve.

[0014] In a preferred embodiment, the upper part of the cleaning agent outlet pipe is a narrow pipe section, the cleaning agent output valve is located on the narrow pipe section, the lower part of the cleaning agent outlet pipe is a wide pipe section, and the filter mechanism is located in the wide pipe section.

[0015] In a preferred embodiment, the filtration mechanism includes a filter baffle inclinedly disposed within a wide pipe section, a filter screen disposed on the filter baffle, the filter screen being located directly below a narrow pipe section, and an inclined tube disposed on one side of the wide pipe section, the filter baffle being able to move inclinedly into the inclined tube within the wide pipe section.

[0016] In a preferred embodiment, a pusher cylinder is provided at the end of the inclined tube, and the pusher rod of the pusher cylinder is inserted obliquely into the inclined tube and connected and fixed between it and the filter baffle.

[0017] The inclined tube has a downward filter cake lower tube near the wide tube section. A slag-removing plate is provided in the inclined tube above the filter cake lower tube. A gap is reserved between the slag-removing plate and the bottom surface of the inclined tube for the filter baffle to pass through.

[0018] In a preferred embodiment, the inner walls of the wide pipe section and the inclined pipe are provided with side guide grooves, and the filter baffle is located in the side guide grooves on both sides.

[0019] The apparatus for preparing an aminosulfonic acid cleaning agent provided by this utility model, by adopting the above-described structure, has the following beneficial effects:

[0020] (1) While the stirring blades are driven by the rotating shaft to carry out the stirring operation, the aminosulfonic acid raw material in the aminosulfonic acid raw material buffer tank is slowly added by the spiral feeding blades. This can avoid the problem of a large amount of raw material rushing in at one time, causing the local concentration to be too high and affecting the product quality, and ensure the uniformity of stirring.

[0021] (2) By using an additive distribution tray, the position of the additive in the solution is changed, thereby improving the uniformity of the additive distribution and enhancing the final effect of the aminosulfonic acid cleaning agent;

[0022] (3) After the cleaning agent is prepared, the undissolved raw material particles or impurities are filtered through the filter mechanism set in the cleaning agent outlet pipe and inclined pipe, and the slag discharge is automated, which improves the purity of the cleaning agent and simplifies the treatment steps of the filter residue.
