Description

Technical Field

[0001] The utility model relates to the technical field of desizing wastewater treatment, in particular to a desizing wastewater treatment pool. Background Art

[0002] In the textile industry, desizing wastewater is a type of wastewater containing fibers, sediments, suspended matter and chemicals generated during the slurry production process. Desizing is the process of using chemical agents to hydrolyze the slurry on the fabric to form soluble substances, which are then removed. The water volume is small but the pollutant concentration is high. It contains various slurries, slurry decomposition products, fiber scraps, starch alkali and various additives, making the wastewater alkaline. Therefore, it is necessary to use acid precipitation to separate the solid and liquid of the wastewater. In the treatment of desizing wastewater, acid precipitation mainly changes the acidity and alkalinity of the water body, so that certain specific substances are converted from dissolved or colloidal states to suspended states under this condition, and then the suspended substances are removed by continuing to use flocculation precipitation, flotation methods, etc. After adding the acidic liquid, it is necessary to aerate the wastewater and the acidic liquid through aeration plates to disturb the mixing.

[0003] In the process of sewage treatment, the air source is certain, which is not only supplied to the desizing wastewater treatment tank, but also to the biochemical tank. The amount of wastewater that needs to be treated in the desizing wastewater treatment tank fluctuates, while the pressure of the air source is generally constant, and the airflow in the aeration pipe cannot be adjusted. When there is more wastewater, the aeration plate in the treatment tank needs to be aerated when it encounters greater resistance, otherwise the resistance is smaller. These resistances will directly affect the aeration volume of the aeration plate, thereby causing the aeration volume of the desizing wastewater treatment tank to fluctuate greatly, affecting the effect of acid precipitation and stirring. Utility Model Content

[0004] The technical problem to be solved by the utility model is: a desizing wastewater treatment pool, which can change the size of aeration as the liquid level in the pool changes, thereby improving the use effect.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a desizing wastewater treatment pool, including a wastewater treatment pool, a plurality of airflow pipes are evenly arranged at the bottom of the wastewater treatment pool, a plurality of aeration plates are provided on the airflow pipes, the airflow pipes are gathered to a main air pipe, the main air pipe is connected to an external air intake pipe, an airflow control box for adjusting the size of the airflow in the air intake pipe is provided on the air intake pipe, a rotating rod is rotatably connected to one side of the airflow control box, the rotating angle of the rotating rod corresponds to the size of the airflow in the air intake pipe, a rotating adjustment structure for adjusting the angle of the rotating rod is provided on the rotating rod, the rotating angle of the rotating rod rotates with the change of the liquid level in the wastewater treatment pool, and a drain outlet for convenient drainage is provided on the wastewater treatment pool.

[0006] As a preferred solution, the airflow control box includes a rotating sphere and an outer box body, the rotating sphere is rotatably installed in the outer box body, the outer box body is provided with an airflow channel connected to the air intake pipe, the rotating ball is provided with a through channel connected to the airflow channel, the rotating sphere is provided with a connecting shaft connected to the rotating rod, and the connecting shaft is provided with a reset structure.

[0007] As a preferred solution, the rotation adjustment structure includes a pulley fixed at the top of one side of the wastewater treatment tank, an adjustment float is provided in the wastewater treatment tank, the adjustment float and the end of the rotating rod are connected by a traction rope, and the traction rope passes through the pulley.

[0008] As a preferred solution, the reset structure includes a torsion spring, which is sleeved on the connecting shaft, one end of the torsion spring is fixed to the rotating rod, and the other end of the torsion spring is fixed to the outer box body.

[0009] As a preferred solution, a limit block for limiting the rotation rod is provided on the outer box body.

[0010] As a preferred solution, sealing rings are provided on both sides of the rotating sphere at the through-channel, and a rotating bearing is provided between the connecting shaft and the outer box body.

[0011] After adopting the above technical scheme, the effect of the utility model is as follows: since the desizing wastewater treatment pool includes a wastewater treatment pool, a plurality of airflow pipes are evenly arranged at the bottom of the wastewater treatment pool, a plurality of aeration plates are arranged on the airflow pipes, the airflow pipes are collected at the main air pipe, the main air pipe is connected to the external air intake pipe, the air intake pipe is provided with an airflow control box for adjusting the size of the airflow in the air intake pipe, one side of the airflow control box is rotatably connected to a rotating rod, the rotating angle of the rotating rod corresponds to the size of the airflow in the air intake pipe, and the rotating rod is provided with a rotating rod for adjusting the angle of the rotating rod The regulating structure is characterized in that the rotation angle of the rotating rod rotates with the change of the liquid level in the wastewater treatment tank, and the wastewater treatment tank is provided with a drain outlet for convenient drainage; when wastewater is poured into the wastewater treatment tank and then subjected to acid precipitation treatment, the rotating regulating structure is rotated to regulate and rotate the rotating rod, thereby controlling the size of the airflow passing through the airflow control box, which is suitable for the amount of wastewater in the wastewater treatment tank. The airflow is dispersed to each airflow pipeline through the main air pipe, and the wastewater is disturbed and mixed fully through aeration of the aeration disk; the treatment tank can change the size of aeration as the liquid level in the tank changes, thereby improving the use effect.

[0012] Furthermore, since the airflow control box includes a rotating sphere and an outer box body, the rotating sphere is rotatably installed in the outer box body, the outer box body is provided with an airflow channel connected to the air intake pipe, the rotating ball is provided with a through channel connected to the airflow channel, the rotating sphere is provided with a connecting shaft connected to a rotating rod, and the connecting shaft is provided with a reset structure; when the rotating rod rotates, it can drive the connecting shaft to rotate, thereby causing the rotating ball to rotate, so that the through channel and the airflow channel will not be completely open to it, the flow rate can be effectively adjusted, and effective reset can be ensured through the reset structure.

Through the traction rope and the pulley, when the adjusting float descends, the rotating rod is pulled to swing upward, so that the rotating ball also rotates, the through channel and the airflow channel deviate, and the airflow is reduced; when the adjusting float rises, the reset structure helps the rotating rod to reset, which can ensure that the through channel and the airflow channel can be accurately connected and the airflow is maximized.

[0014] Furthermore, since the reset structure includes a torsion spring, the torsion spring is sleeved on the connecting shaft, one end of the torsion spring is fixed to the rotating rod, and the other end of the torsion spring is fixed to the outer box body; in this way, when the rotating rod rotates, the torsion spring can be deformed. Since the adjusting float has a certain gravity when it descends, the torsion spring cannot be reset. When the adjusting float rises, the gravity decreases, so the torsion spring can complete the reset and completely connect the through channel and the air flow channel.

[0015] Furthermore, since a limit block for limiting the position of the rotating rod is provided on the outer box body, the rotating rod is prevented from rotating at an excessive angle, the rotation range is limited, and accurate airflow regulation is ensured.

[0016] Furthermore, since the rotating sphere is provided with sealing rings on both sides of the through channel, a rotating bearing is provided between the connecting shaft and the outer box body; thus, a good sealing effect of air flow delivery is ensured and the rotation of the connecting shaft is facilitated.

[0023] The present invention is further described in detail below through specific embodiments.

[0024] like Figure 1 and Figure 2 As shown, a desizing wastewater treatment pool comprises a wastewater treatment pool 1, a plurality of airflow pipes 2 are evenly arranged at the bottom of the wastewater treatment pool 1, a plurality of aeration plates 3 are arranged on the airflow pipes 2, the airflow pipes 2 are gathered to a main air pipe 4, the main air pipe 4 is connected to an external air intake pipe 21, an airflow control box 5 for adjusting the size of the airflow in the air intake pipe 21 is provided on the air intake pipe 21, a rotating rod 6 is rotatably connected to one side of the airflow control box 5, the rotating angle of the rotating rod 6 corresponds to the size of the airflow in the air intake pipe, a rotating adjustment structure for adjusting the angle of the rotating rod 6 is provided on the rotating rod 6, the rotating angle of the rotating rod 6 rotates with the change of the liquid level of the wastewater treatment pool 1, and a drain outlet 7 for convenient drainage is provided on the wastewater treatment pool 1.

[0025] Three air flow pipes 2 are respectively provided at the bottom of the wastewater treatment tank 1, and the three air flow channels 10 are interconnected. Four aeration plates 3 are installed on each air flow channel 10, so that the aeration plates 3 are evenly distributed in the wastewater treatment tank 1. The aeration plates 3 are existing structures and are not described in detail herein.

[0026] like Figure 1 and Figure 4As shown, the airflow control box 5 includes a rotating ball 8 and an outer box 9, the rotating ball 8 is rotatably installed in the outer box 9, the outer box 9 is provided with an airflow channel 10 connected to the air inlet pipe 21, the rotating ball is provided with a through channel 11 connected to the airflow channel 10, the rotating ball is provided with a connecting shaft 12 connected to the rotating rod 6, and the connecting shaft 12 is provided with a reset structure; the outer box 9 is arranged on the air inlet pipe 21 for easy adjustment, and the rotating ball 8 is connected to the rotating rod 6, so that when the rotating rod 6 rotates, the rotating ball 8 will also rotate, so that the corresponding through channel 11 and airflow channel 10 will deviate, resulting in a reduction in airflow passing through, thereby changing the size of aeration; effective reset can be ensured by the reset structure.

[0027] As Figure 2 and Figure 3 As shown, the rotation adjustment structure includes a pulley 13 fixed at the top of one side of the wastewater treatment tank 1, and an adjustment float 14 is arranged in the wastewater treatment tank 1. The adjustment float 14 and the end of the rotating rod 6 are connected by a traction rope 15, and the traction rope 15 passes through the pulley 13; the adjustment float 14 can float effectively in the wastewater treatment tank 1, and rise and fall with the rise and fall of the liquid level. Through the traction rope 15 and the pulley 13, when the adjustment float 14 descends, the rotating rod 6 is pulled upward to swing, so that the rotating ball 8 also rotates, and the through channel 11 and the air flow channel 10 deviate, and the air flow is reduced; when the adjustment float 14 rises, the reset structure helps the rotating rod 6 to reset, so that it can ensure that the through channel 11 and the air flow channel 10 can be accurately connected and the air flow is maximized; in this way, the adjustment float 14 can adjust the size of aeration with the change of the liquid level, improve the use effect, and ensure that the wastewater treatment tank 1 can fully mix and react.

[0028] Furthermore, the reset structure includes a torsion spring 16, which is sleeved on the connecting shaft 12, one end of the torsion spring 16 is fixed to the rotating rod 6, and the other end of the torsion spring 16 is fixed to the outer box body 9; when the adjusting float 14 drives the rotating rod 6 to rotate, the torsion spring 16 will be deformed by force, and the airflow will be adjusted. At this time, the rotating rod 6 cannot be reset under the force of the torsion spring 16. When the adjusting float 14 rises, the rotating rod 6 loses traction, and the torsion spring 16 can drive the rotating rod 6 to reset, thereby ensuring maximum airflow.

[0029] In this embodiment, the outer box body 9 is provided with a limit block for limiting the rotating rod 6, and the limit block includes an upper limit block 17 and a lower limit block 18. The lower limit block 18 is located below the rotating rod 6 and the through channel 11 and the air flow channel 10 are fully open, and the upper limit block 17 is located above the rotating rod 6 and the through channel 11 and the air flow channel 10 reach a hole for minimum air flow. Since the through channel 11 and the air flow channel 10 need to ensure a certain opening connection, the rotating ball 8 does not need a large rotation range. The upper limit block 17 and the lower limit block 18 are used to limit the swing angle of the rotating rod 6, so as to limit the rotation angle of the rotating ball 8, thereby ensuring that the rotating rod 6 rotates accurately during use and the air flow can pass effectively.

[0030] The rotating sphere 8 is provided with sealing rings 19 on both sides of the through channel 11, and a rotating bearing 20 is provided between the connecting shaft 12 and the outer box body 9; the sealing ring 19 ensures a good sealing effect of air flow conveying, and the rotating bearing 20 facilitates the rotation of the connecting shaft 12 and reduces wear.

[0031] The working principle of this embodiment is as follows: when wastewater is poured into the wastewater treatment tank 1, the regulating float 14 will rise, the rotating rod 6 will be on the lower limit block 18, and then the acid precipitation treatment will be carried out. The air inlet pipe 21 will transport airflow to each airflow pipe 2, and the aeration plate 3 will perform aeration. When the liquid level drops, the regulating float 14 will drop, pulling the rotating rod 6, and the rotating rod 6 will cause the rotating ball to start rotating, and the airflow in the airflow pipe 2 will start to decrease, and the wastewater in the wastewater treatment tank 1 will continue to be aerated and mixed.

[0032] The above-described embodiments are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Various modifications and alterations to the technical solution of the present invention, without departing from the design spirit of the present invention, should fall within the scope of protection defined in the claims of the present invention.
