Description

Technical Field

[0001] This utility model relates to the technical field of hydrochloric acid recovery equipment, specifically a concentration device for hydrochloric acid regeneration. Background Technology

[0002] Large quantities of hydrochloric acid-containing wastewater are generated in many industrial processes, such as chemical and metallurgical manufacturing. To achieve resource recycling and environmental protection, this wastewater needs to be regenerated. Concentration is a crucial step in the hydrochloric acid regeneration process.

[0003] Patent CN216614046U discloses a novel hydrochloric acid concentration device for hydrochloric acid regeneration, comprising a main body, a water inlet pipe, a discharge pipe, a feed pipe, a limiting mechanism, and a sealing mechanism. The water inlet pipe is fixedly connected to the outside of one side of the main body and extends into the inside of the main body; the discharge pipe is fixedly connected to the outside of one side of the main body and located below the water inlet pipe; the feed pipe is slidably connected to the top of the main body and extends into the inside of the main body; the limiting mechanism is located at the top of the main body and extends into the inside of the feed pipe for limiting the feed pipe; the sealing mechanism is located inside the main body and the feed pipe and extends into the inner wall of the main body for increasing the sealing performance of the main body.

[0004] Although the above-mentioned device can solve the corresponding technical problems, its concentration efficiency is low and the processing time is long during use, which increases production costs. Utility Model Content

[0005] The purpose of this invention is to provide a concentration device for hydrochloric acid regeneration, so as to solve the technical problems of low concentration efficiency, long processing time and high cost of existing equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A hydrochloric acid regeneration concentration device includes an outer shell, inside which a hydrochloric acid regeneration concentration tank and a heating base are disposed. The top of the hydrochloric acid regeneration concentration tank is equipped with a top cover, on which an inlet, an outlet and a stirring mechanism are respectively installed.

[0008] The top of the cover is connected to one end of a connecting pipe, and the other end of the connecting pipe is connected to the air inlet of the condenser.

[0009] The above technical solution, by setting up a stirring mechanism in conjunction with a heating base, can ensure that the hydrochloric acid solution is heated evenly, avoiding problems such as local overheating leading to hydrochloric acid decomposition. This greatly reduces production costs and improves concentration efficiency.

[0010] As a further embodiment of this invention, the heating base is disposed between the hydrochloric acid regeneration and concentration tank and the outer shell.

[0011] The above technical solution includes an outer shell and a hydrochloric acid regeneration and concentration tank, with the hydrochloric acid regeneration and concentration tank housed within the outer shell. A heating base is installed at the bottom of the hydrochloric acid regeneration and concentration tank. This double-layer structure reduces heat loss and improves heating efficiency, thereby shortening the hydrochloric acid concentration time and increasing concentration efficiency.

[0012] As a further embodiment of this invention, the hydrochloric acid regeneration and concentration tank is made of glass.

[0013] The above technical solution uses glass to construct the hydrochloric acid regeneration and concentration tank, which is then built into the outer shell to form an isolation layer. This prevents hydrochloric acid from coming into direct contact with the metal, thereby reducing the corrosion of the tank substrate by hydrochloric acid and significantly extending its service life.

[0014] As a further embodiment of this invention, a temperature sensor is installed inside the hydrochloric acid regeneration and concentration tank.

[0015] The above technical solution, by setting up a temperature sensor, can monitor the heating temperature of hydrochloric acid to ensure the stability of hydrochloric acid concentration and improve product quality.

[0016] As a preferred embodiment of this utility model, the stirring mechanism includes a motor, which is fixed on the top of the cover. A connecting rod is installed on the rotating shaft of the motor, and a stirring rod is installed at one end of the connecting rod. The stirring rod is fixed by a pin, and a spring is installed between the pin and the connecting rod.

[0017] The above technical solution incorporates a stirring mechanism that uses a motor to drive a connecting rod to rotate within the hydrochloric acid regeneration and concentration tank, thereby stirring the hydrochloric acid. Combined with heating from the heating base, this significantly improves concentration efficiency, ensures uniform heating of the hydrochloric acid solution, and prevents localized overheating that could lead to hydrochloric acid decomposition.

[0018] As a further preferred embodiment of this utility model, the top of the stirring rod is integrally formed with a square plug, which is inserted into one end of the connecting rod. The square plug has a socket, which is used to connect with the pin.

[0019] The above technical solution involves integrally forming a square plug at one end of the stirring rod, which is then inserted into the connecting rod and fixed with a pin. This allows for quick installation and maintenance of the stirring rod, greatly improving the ease of use of the equipment.

[0020] Compared with the prior art, the beneficial effects of the hydrochloric acid regeneration concentration equipment of this utility model are as follows: by setting up a stirring mechanism in conjunction with a heating base, this utility model can make the hydrochloric acid solution heat evenly, avoid local overheating leading to hydrochloric acid decomposition, reduce production costs, and improve concentration efficiency.

[0029] See Figures 1-3 As shown in the figure, an embodiment of the present invention provides a hydrochloric acid regeneration concentration device, including an outer shell 101, a hydrochloric acid regeneration concentration tank 102 and a heating base 103 disposed inside the outer shell 101, and an upper cover 201 installed on the top of the hydrochloric acid regeneration concentration tank 102, on which an inlet 301, an outlet 401 and a stirring mechanism 701 are respectively installed.

[0030] The top of the upper cover 201 is connected to one end of the connecting pipe 501, and the other end of the connecting pipe 501 is connected to the air inlet of the condenser 601.

[0031] The condenser 601 adopts existing technical solutions, which will not be described in detail here.

[0032] The heating base 103 has a built-in electric heating wire and is positioned between the hydrochloric acid regeneration concentration tank 102 and the outer shell 101. In this embodiment, the hydrochloric acid regeneration concentration tank 102 is housed within the outer shell 101, and the heating base 103 is located at the bottom of the hydrochloric acid regeneration concentration tank 102. This double-layer structure reduces heat loss, improves heating efficiency, and thus shortens the hydrochloric acid concentration time and increases concentration efficiency.

[0033] The hydrochloric acid regeneration and concentration tank 102 is made of glass and is built into the outer shell 101 to form an isolation layer, preventing hydrochloric acid from coming into direct contact with the metal, thereby reducing the corrosion of the tank substrate by hydrochloric acid and greatly extending its service life.

[0034] A temperature sensor 801 is installed inside the hydrochloric acid regeneration and concentration tank 102. It can monitor the heating temperature of the hydrochloric acid solution to ensure the stability of the hydrochloric acid concentration and improve product quality. The temperature sensor 801 can be a PT100 temperature sensor. The temperature sensor 801 is electrically connected to the display of the built-in controller to display the heating temperature. The controller can be a single-chip microcomputer of model STC89C51.

[0035] The stirring mechanism 701 includes a motor 702, which is fixed to the top of the upper cover 201. A connecting rod 705 is mounted on the rotating shaft of the motor 702, and a stirring rod 703 is mounted on one end of the connecting rod 705. The stirring rod 703 is fixed by a pin 706, and a spring 707 is installed between the pin 706 and the connecting rod 705. This invention utilizes the motor 702 to drive the connecting rod 705 to rotate, causing the connecting rod 705 to drive the stirring rod 703 to rotate inside the hydrochloric acid regeneration concentration tank 102, thereby stirring the hydrochloric acid. Under the heating of the heating base 103, the concentration efficiency is greatly improved, the hydrochloric acid solution is heated evenly, and the problem of hydrochloric acid decomposition caused by local overheating is avoided.

[0036] The top of the stirring rod 703 is integrally formed with a square plug 704, which is inserted into one end of the connecting rod 705. The square plug 704 has a socket 708, which is used to engage with a pin 706. By integrally forming the square plug 704 at one end of the stirring rod 703, inserting it into the connecting rod 705, and fixing it with the pin 706, the stirring rod 703 can be quickly installed and maintained, greatly improving the ease of use of the equipment.

[0037] In this embodiment of the invention, the recovered hydrochloric acid solution is injected into the hydrochloric acid regeneration concentration tank 102 through the feed inlet 301. The heating base 103 is activated to heat the hydrochloric acid regeneration concentration tank 102, causing the recovered hydrochloric acid to separate from the water. During this process, the motor 702 on the stirring mechanism 701 drives the connecting rod 705 to rotate, causing the connecting rod 705 to drive the stirring rod 703 to rotate inside the hydrochloric acid regeneration concentration tank 102, thereby stirring the hydrochloric acid solution. Under the heating of the heating base 103, the concentration efficiency is greatly improved, and the hydrochloric acid solution is heated evenly, avoiding problems such as local overheating leading to hydrochloric acid decomposition. At the same time, the condenser 601 collects and recovers the hydrochloric acid and water vapor in the hydrochloric acid regeneration concentration tank 102 through the connecting pipe 501, thereby reducing the waste of hydrochloric acid and also reducing the harm of hydrochloric acid volatilization to the working environment and the health of operators.

[0038] This embodiment of the invention uses a stirring mechanism 701 in conjunction with a heating base 103. A motor 702 drives a connecting rod 705 to rotate, which in turn drives a stirring rod 703 to rotate within the hydrochloric acid regeneration and concentration tank 102, thereby stirring the hydrochloric acid. Under the heating of the heating base 103, the concentration efficiency is greatly improved, the hydrochloric acid solution is heated evenly, and problems such as local overheating leading to hydrochloric acid decomposition are avoided, thus significantly improving the concentration efficiency of hydrochloric acid.

[0039] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
