Description

Technical Field

[0001] This utility model relates to the field of membrane-specific reducing agent processing technology, and in particular to a uniform stirrer for membrane-specific reducing agent processing. Background Technology

[0002] Membrane separation technology is widely used in water treatment, chemical industry, pharmaceutical industry, food processing and other fields. During membrane separation, reducing agents (such as sodium bisulfite, sodium thiosulfate, etc.) are often used to remove oxidizing substances from the membrane surface or to clean the membrane surface. When processing reducing agents, they need to be evenly dispersed in the solution to avoid excessively high local concentrations that could damage the membrane or lead to incomplete chemical reactions.

[0003] In the prior art, patent publication number CN221580381U discloses a uniform stirrer for processing reducing agent in reverse osmosis membranes, including a stirring tank. A discharge pipe is fixedly connected to the bottom of the stirring tank, and a discharge valve is installed at the bottom of the discharge pipe. A tank cover is installed at the top of the stirring tank, and a feed pipe is fixedly connected to the upper surface of the tank cover. A rotating cylinder is rotatably connected to the center of the upper surface of the tank cover. A set of stirring blades is uniformly fixedly connected to the outer peripheral sidewall of the rotating cylinder. The rotating cylinder is equipped with a material-turning structure, and a first bevel gear is fixedly connected to the top of the rotating cylinder. This invention, through the rotating cylinder, stirring blades, material-turning structure, first bevel gear, rotating shaft, second bevel gear, third bevel gear, and stirring blades, can fully stir the reducing agent at the bottom and turn the reducing agent at the bottom, facilitating thorough mixing with the reducing agent at the top, shortening the stirring time, and improving processing efficiency.

[0004] Although the aforementioned reverse osmosis membrane reducing agent homogenizer can achieve the effect of mixing and processing the reducing agent through the setting of rotating drum, stirring blades and material turning structure, it still has the following shortcomings in practical applications: traditional stirrers are mostly designed with unidirectional blades, the reducing agent flows in a single direction, the stirring efficiency is low and there are many dead corners. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a membrane-specific reducing agent homogenizing stirrer.

[0006] To achieve this objective, the present invention adopts the following technical solution: a uniform mixer for processing membrane reducing agents, comprising a mixing tank, a feed pipe fixedly inserted into the top wall of the mixing tank, a bidirectional mixing assembly rotatably installed inside the mixing tank, a discharge pipe fixedly inserted into the bottom wall of the mixing tank, a material valve fixedly installed around the discharge pipe, multiple support legs evenly fixedly installed at the bottom of the mixing tank, and a flushing assembly fixedly installed on the top wall of the mixing tank. The bidirectional mixing assembly includes a main shaft rotatably installed on the upper and lower inner walls of the mixing tank, a drive motor fixedly installed on the top of the mixing tank, the output end of the drive motor penetrating through the top wall of the mixing tank and fixedly connected to the top end of the main shaft, multiple forward spiral blades evenly fixedly installed around the main shaft, a fixed cylinder fixedly sleeved around the periphery of the forward spiral blades, and multiple reverse spiral blades evenly fixedly installed around the periphery of the fixed cylinder.

[0007] Preferably, the reverse spiral blades abut against the inner wall of the mixing tank.

[0008] Preferably, the rinsing assembly includes a water pump fixedly installed on the top of the mixing tank, and multiple nozzles are evenly fixedly installed on the inner wall of the top of the mixing tank. The water inlet of the water pump is connected to an external water source, and the water outlet of the water pump is connected to the nozzles.

[0009] Preferably, an inhibition plate is fixedly installed on the bottom inner wall of the mixing tank, and the inhibition plate has multiple disturbance holes unevenly opened.

[0010] The beneficial effects of this invention are as follows: When using this device, raw materials are added to the mixing tank through the feed pipe. The drive motor is started to drive the main shaft to rotate between the upper and lower inner walls of the mixing tank. The main shaft drives multiple forward spiral blades and a fixed cylinder fixedly sleeved around the forward spiral blades to rotate, thereby stirring the reducing agent in the mixing tank and pushing the reducing agent from the bottom to the top. The fixed cylinder drives multiple reverse spiral blades to rotate, thereby stirring the reducing agent while pushing it from the top to the bottom. Through these settings, the device can form a stable circulating flow field through the bidirectional flow of the fixed cylinder and the forward spiral blades, ensuring that the reducing agent particles are evenly distributed throughout the container, improving stirring efficiency and reducing dead zones. The reverse spiral blades can continuously scrape the inner wall of the mixing tank while rotating, preventing the reducing agent particles from adhering to the inner wall of the mixing tank. After the membrane-specific reducing agent is stirred and discharged, the water pump is started to spray external cleaning water through multiple nozzles to rinse the inside of the mixing tank. Through these settings, the device can automatically clean itself after the stirring operation is completed, preventing residual reducing agent from affecting the quality of subsequent reducing agent processing.

Example 1

[0019] like Figure 1-3 As shown, the present invention proposes a uniform mixer for processing membrane reducing agents, comprising a mixing tank 1, a feed pipe 4 fixedly inserted into the top wall of the mixing tank 1, a bidirectional mixing assembly 2 rotatably installed inside the mixing tank 1, a discharge pipe 5 fixedly inserted into the bottom wall of the mixing tank 1, a material valve 6 fixedly installed around the discharge pipe 5, multiple support legs 7 uniformly fixedly installed at the bottom of the mixing tank 1, and a rinsing assembly 3 fixedly installed on the top wall of the mixing tank 1.

[0020] In this embodiment: the bidirectional stirring assembly 2 includes a main shaft 21 rotatably mounted on the upper and lower inner walls of the stirring tank 1. A drive motor 22 is fixedly mounted on the top of the stirring tank 1. The output end of the drive motor 22 penetrates the top wall of the stirring tank 1 and is fixedly connected to the top end of the main shaft 21. This arrangement allows the drive motor 22 to rotate the main shaft 21 between the upper and lower inner walls of the stirring tank 1. Multiple forward spiral blades 23 are evenly fixedly mounted on the periphery of the main shaft 21. A fixed sleeve 24 is fixedly fitted around the periphery of the forward spiral blades 23. This arrangement allows the main shaft 21 to drive multiple forward spiral blades 23 to rotate when rotating. The forward spiral blade 23 and the fixed cylinder 24 fixedly sleeved around the forward spiral blade 23 rotate, thereby stirring the reducing agent in the mixing tank 1 and pushing the reducing agent from the bottom to the top; multiple reverse spiral blades 25 are uniformly fixedly installed around the fixed cylinder 24. Through this setting, the multiple reverse spiral blades 25 rotate with the rotation of the fixed cylinder 24, thereby stirring the reducing agent and pushing the reducing agent from the top to the bottom at the same time. The bidirectional flow of the fixed cylinder 24 and the forward spiral blade 23 can form a stable circulating flow field, ensuring that the reducing agent particles are evenly distributed in the entire container. Example 2

[0021] like Figure 1-3As shown, the present invention proposes a membrane-specific reducing agent processing homogenizer. Compared with Embodiment 1, this embodiment further includes a reverse spiral blade 25 abutting against the inner wall of the mixing tank 1. This arrangement allows the reverse spiral blade 25 to continuously scrape the inner wall of the mixing tank 1 while rotating, preventing reducing agent particles from adhering to the inner wall of the mixing tank 1. The rinsing assembly 3 includes a water pump 31 fixedly installed on the top of the mixing tank 1. Multiple nozzles 32 are evenly fixedly installed on the inner wall of the top of the mixing tank 1. The water inlet of the water pump 31 is connected to an external water source, and the water outlet of the water pump 31 is connected to the nozzles 32. The connection allows the water pump 31 to spray external cleaning water through multiple nozzles 32 after the membrane-specific reducing agent has been stirred and discharged, thereby rinsing the inside of the mixing tank 1 and preventing residual reducing agent from affecting the quality of subsequent reducing agent processing. An inhibition plate 8 is fixedly installed on the bottom inner wall of the mixing tank 1. Multiple disturbance holes 9 are unevenly opened on the inhibition plate 8. This setting can break the vortex structure generated on the bottom inner wall of the mixing tank 1 during the stirring of the reducing agent, prevent reducing agent particles from depositing at the bottom, enhance the disturbance effect of the bottom liquid, and improve the stirring uniformity.

[0022] Working Principle: When using this device, raw materials are added to the mixing tank 1 through the feed pipe 4. The drive motor 22 is started to drive the main shaft 21 to rotate between the upper and lower inner walls of the mixing tank 1. The main shaft 21 drives multiple forward spiral blades 23 and the fixed cylinder 24 fixedly sleeved around the forward spiral blades 23 to rotate, thereby stirring the reducing agent in the mixing tank 1 and pushing the reducing agent from the bottom to the top. The fixed cylinder 24 drives multiple reverse spiral blades 25 to rotate, thereby stirring the reducing agent and pushing the reducing agent from the top to the bottom at the same time. The bidirectional flow of the fixed cylinder 24 and the forward spiral blades 23 can form a stable circulating flow field to ensure that the reducing agent particles are evenly distributed in the entire container. The reverse spiral blades 25 can continuously scrape the inner wall of the mixing tank 1 while rotating, preventing the reducing agent particles from adhering to the inner wall of the mixing tank 1. After the membrane-specific reducing agent is stirred and discharged, the water pump 31 is started to spray external cleaning water through multiple nozzles 32 to rinse the inside of the mixing tank 1 and prevent residual reducing agent from affecting the quality of subsequent reducing agent processing.

[0023] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
