Description

Technical Field

[0001] This application relates to the field of alkali reduction machines, and more particularly to a wastewater treatment device for an alkali reduction machine. Background Technology

[0002] Polyester's unique structure and molecular chain arrangement result in poor moisture absorption and a relatively stiff feel. To improve its performance in everyday wear, it typically requires alkali reduction treatment.

[0003] Using alkali-resistant disperse dyes, polyester fabrics are alkali-reduced and dyed in the same bath. Because the dye and alkali are treated in the same bath, the polyester oligomers precipitated at high temperature are well dispersed in the alkaline dye bath. Therefore, the reduction washing step can be omitted after dyeing.

[0004] Alkali reduction treatment generates a large amount of dyeing wastewater containing many chemical substances, which requires chemical neutralization. This is usually done manually, but the amount of material to be added varies depending on the amount of wastewater. Manual addition is prone to errors and is inconvenient. Utility Model Content

[0005] To address the issues of errors and inconvenience in manual feeding under varying wastewater volumes, this application provides a wastewater treatment device using an alkali reduction machine.

[0006] The wastewater treatment device for an alkali reduction machine provided in this application adopts the following technical solution:

[0007] A wastewater treatment device for an alkali reduction machine includes a tank body. A waste pipe for inletting wastewater is provided at the top of the tank body. A stirring mechanism is provided inside the tank body. A dosing tank is provided on the top of the tank body. A feed pipe is provided below the dosing tank and inside the tank body. The feed pipe has an inlet. A valve mechanism for opening and closing the inlet is provided inside the tank body. An adjustment mechanism for controlling the opening degree of the inlet is provided at the inlet of the tank body. A floating mechanism that moves with the liquid level in the tank body is provided inside the tank body. The floating mechanism is connected to the adjustment mechanism.

[0008] By adopting the above technical solution, wastewater is transported into the tank through the waste pipe. At this time, the floating mechanism moves with the rise of the liquid level in the tank, driving the regulating mechanism to adjust the opening of the feed inlet. At this time, the valve mechanism opens, and the feeding box adds chemicals into the tank. After the chemical addition is completed, the valve mechanism closes. At this time, the stirring mechanism stirs and treats the wastewater. The floating mechanism drives the regulating mechanism to adjust the opening of the feed inlet according to the wastewater volume, thereby adjusting the amount of chemicals added. The adjustment operation is convenient.

[0009] Optionally, the adjusting mechanism includes a sliding plate, which is slidably installed at the inlet of the feed pipe and located below the valve mechanism. The sliding plate closes the inlet of the feed pipe. Two sliding plates are provided and distributed opposite to each other. The two sliding plates slide in opposite or opposite directions. A connecting member is provided on one side of the sliding plate and the connecting member is connected to the floating mechanism.

[0010] By adopting the above technical solution, after the floating mechanism is moved by buoyancy, the sliding plates on both sides are driven to slide through the connecting parts. When the liquid level in the tank is different, the floating mechanism is located at different heights, and the sliding plates on both sides are located at different positions. At this time, the opening size of the feed pipe inlet is different, and the feed rate is adjusted by adjusting the size of the feed pipe inlet.

[0011] Optionally, the floating mechanism includes a float and a connecting rod, the connecting rod being connected to the connector, and the float being disposed at one end of the connecting rod.

[0012] By adopting the above technical solution, the float is lifted by the buoyancy of the liquid surface, which drives the connecting rod to move. The connecting rod pushes the connecting piece and then drives the sliding plate to slide, making the adjustment operation of the sliding plate convenient.

[0013] Optionally, the connector includes a connecting rod, a slide rail is provided inside the housing, the slide rail is distributed along the sliding direction of the sliding plate, a slider is provided on the sliding plate, the slider is slidably installed at the slide rail, one end of the connecting rod is rotatably connected to the slider, and the end of the connecting rod away from the slider is rotatably connected to the end of the connecting rod away from the float.

[0014] By adopting the above technical solution, when the float is lifted by buoyancy, the connecting rod moves, which in turn pushes the connecting rod to rotate. The end of the connecting rod away from the connecting rod pushes the slider to slide along the slide rail, which in turn drives the sliding plate to move to the feed inlet of the feed pipe and open. When the wastewater in the tank is discharged, the connecting rod returns to its original position, pulls the connecting rod and drives the sliding plate to its original position, and at this time the feed inlet is closed, and the feed inlet is opened and closed simultaneously.

[0015] Optionally, a screw is threaded to the end of the connecting rod away from the dosing tank, and the float is located at the end of the screw away from the connecting rod.

[0016] By adopting the above technical solution, the position of the float is adjusted by rotating the screw, the movement of the connecting rod is adjusted, and thus the opening of the sliding plate is adjusted, which is suitable for dosing operations under different dosing requirements.

[0017] Optionally, the housing is provided with a limiting guide rail, which is distributed in a direction perpendicular to the slide rail. A limiting block is provided on the end of the connecting rod away from the float and on the side away from the dosing tank. The limiting block slides along the limiting guide rail. A spring is provided on the limiting guide rail, and one end of the spring is connected to one side of the limiting block.

[0018] By adopting the above technical solution, when the connecting rod moves, the limiting block on one side of the connecting rod slides along the limiting guide rail. At this time, the spring is stretched to guide and limit the movement of the connecting rod. When the liquid in the tank is discharged, the spring pushes the connecting rod and the float back to their original positions.

[0019] Optionally, the valve mechanism includes a valve cylinder and a sealing plate. The feed pipe has a through groove on one side of the feed inlet. The sealing plate is slidably installed in the through groove and closes the feed inlet. The valve cylinder is located outside the feed pipe, and the sealing plate is connected to one end of the piston rod of the valve cylinder.

[0020] By adopting the above technical solution, the valve cylinder drives the sealing plate to move, and the sealing plate moves to open and close the feed pipe, making the feeding operation of the feed pipe convenient.

[0021] Optionally, an observation window is rotatably mounted on one side of the housing.

[0022] By adopting the above technical solution, it is convenient to observe the internal condition of the box through the observation window, and the rotating installation makes it easy to open and adjust or repair the internal condition of the box.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Wastewater is fed into the tank through the waste pipe. At this time, the floating mechanism moves with the rise of the liquid level in the tank, driving the regulating mechanism to adjust the opening of the feed inlet. At this time, the valve mechanism opens, and the feeding box adds chemicals into the tank. After the chemical addition is completed, the valve mechanism closes. At this time, the stirring mechanism stirs the wastewater. The floating mechanism drives the regulating mechanism to adjust the opening of the feed inlet according to the wastewater volume, thereby adjusting the amount of chemicals added. The adjustment operation is convenient.

[0025] 2. Rotate the screw to adjust the position of the float, adjust the movement of the connecting rod, and thus adjust the opening of the sliding plate. This is suitable for dosing operations with different dosage requirements.

[0026] 3. It allows for easy observation of the interior of the enclosure through the viewing window, and the rotating installation facilitates opening and adjustment or maintenance of the interior. Attached Figure Description

Detailed Implementation

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] This application discloses a wastewater treatment device for an alkali reduction machine, referring to... Figure 1 and Figure 2 The system includes a housing 1, with a waste pipe 11 at the top for inlet wastewater. Inside the housing 1 is a stirring mechanism 2, comprising a stirring motor 21, a stirring shaft 22, and stirring blades 23. The stirring shaft 22 is vertically rotatable within the housing 1. Several stirring blades 23 are evenly distributed around the circumference of the stirring shaft 22. The stirring motor 21 is located at the top of the housing 1, and the stirring shaft 22 is connected to the output shaft of the stirring motor 21. Wastewater is fed into the housing 1 through the waste pipe 11. During this process, the stirring motor 21 drives the stirring shaft 22 to rotate, which in turn drives the stirring blades 23 to rotate, thus stirring and dispersing the wastewater.

[0034] Reference Figure 1 and Figure 2A dosing tank 12 is provided on the top of the tank body 1. A feed pipe 13 is provided on the lower side of the dosing tank 12 and inside the tank body 1. A feed inlet 131 is provided at the bottom of the feed pipe 13. A sludge discharge pipe 14 is provided at the bottom of the tank body 1. A drain pipe 15 is provided on the side wall of the tank body 1 facing downwards. After the dosing tank 12 adds chemicals to the wastewater in the tank body 1 through the feed inlet 131 of the feed pipe 13, the wastewater is discharged through the drain pipe 15, and the sedimented impurities are discharged through the sludge discharge pipe 14.

[0035] Reference Figure 1 and Figure 2 The tank 1 is equipped with a valve mechanism 3 for opening and closing the feed inlet 131. An adjustment mechanism 4 for controlling the opening of the feed inlet 131 is located within the tank 1. A floating mechanism 5, which moves with the liquid level inside the tank 1, is also installed within the tank 1. The floating mechanism 5 is connected to the adjustment mechanism 4. When wastewater enters the tank 1, the floating mechanism 5 moves with the rising liquid level, driving the adjustment mechanism 4 to adjust the opening of the feed inlet 131. At this time, the valve mechanism 3 opens, and the feeding box adds chemicals to the tank 1. After the chemical addition is complete, the valve mechanism 3 closes, and the stirring mechanism 2 stirs the wastewater. The floating mechanism 5 drives the adjustment mechanism 4 to adjust the opening of the feed inlet 131 according to the wastewater volume, thereby adjusting the dosage. The adjustment operation is convenient.

[0036] Reference Figure 2 and Figure 3 The valve mechanism 3 includes a valve cylinder 31 and a sealing plate 32. The feed pipe 13 has a through groove 132 on one side of the feed port 131. The sealing plate 32 is slidably installed in the through groove 132 in the horizontal direction and closes the feed port 131. The valve cylinder 31 is horizontally arranged outside the feed pipe 13. A connecting plate 33 is provided at one end of the piston rod of the valve cylinder 31. The sealing plate 32 is connected to one side of the connecting plate 33. The valve cylinder 31 drives the sealing plate 32 to move, and the sealing plate 32 moves to open and close the feed pipe 13.

[0037] Reference Figure 2 and Figure 3 The floating mechanism 5 includes a float 51 and a connecting rod 52. A limit guide rail 16 is vertically arranged inside the housing 1. A limit block 521 is located at the upward-facing end of the connecting rod 52, on the side opposite to the dosing tank 12. The limit block 521 slides along the limit guide rail 16. A screw 522 is threadedly connected to the downward-facing end of the connecting rod 52, and the float 51 is positioned at the downward-facing end of the screw 522. The float 51 rises under the buoyancy of the liquid surface, causing the connecting rod 52 to move up and down. Rotating the screw 522 adjusts the position of the float 51 and the amount of movement of the connecting rod 52.

[0038] Reference Figure 2 and Figure 3A spring 161 is provided on the downward side of the limiting guide rail 16. The upward end of the spring 161 is connected to one side of the limiting block 521. When the connecting rod 52 moves, the limiting block 521 on one side of the connecting rod 52 slides along the limiting guide rail 16. At this time, the spring 161 is stretched, which guides and limits the movement of the connecting rod 52. When the liquid in the tank 1 is discharged, the spring 161 pushes the connecting rod 52 and the float 51 back to their original positions.

[0039] Reference Figure 2 and Figure 3 The adjusting mechanism 4 includes a sliding plate 41. A slide rail 17 is arranged horizontally inside the housing 1. The slide rail 17 is distributed along the width direction of the housing 1. There are two slide rails 17 arranged parallel to each other. Slider blocks 411 are arranged on opposite sides of the sliding plate 41. The slider blocks 411 are slidably installed at the slide rail 17. The upward side of the sliding plate 41 is in contact with the downward side of the feed inlet 131 of the feed pipe 13. There are two sliding plates 41 arranged and distributed opposite to each other along the length direction of the slide rail 17. The two sliding plates 41 slide in opposite or opposite directions and the two sliding plates 41 close the feed inlet 131 of the feed pipe 13.

[0040] Reference Figure 2 and Figure 3 A connector is provided on one side of the slider 411. The connector includes a connecting rod 6. One end of the connecting rod 6 is rotatably connected to the side of the slider 411 away from the sliding plate 41. The end of the connecting rod 6 away from the slider 411 is rotatably connected to the upward-facing end of the connecting rod 52. When the float 51 is lifted by buoyancy, the connecting rod 52 moves, thereby pushing the connecting rod 6 to rotate. The end of the connecting rod 6 away from the connecting rod 52 pushes the slider 411 to slide along the slide rail 17, thereby driving the sliding plates 41 on both sides to slide to the feed port 131 of the feed pipe 13 to open. When the liquid level in the tank 1 is different, the floating mechanism 5 is located at different height positions, and the sliding plates 41 on both sides are located at different positions. At this time, the opening size of the feed port 131 of the feed pipe 13 is different, so as to adjust the feed amount. When the wastewater in the tank 1 is discharged, the connecting rod 52 returns to its original position, pulls the connecting rod 6, and then drives the sliding plate 41 to return to its original position. At this time, the feed port 131 is closed, and the feed port 131 is opened and closed simultaneously.

[0041] Reference Figure 1 An observation window 18 is rotatably installed on the side of the box 1 away from the drain pipe 15. The observation window 18 facilitates the observation of the internal condition of the box 1. The rotatable installation makes it easy to open the box 1 for adjustment or maintenance.

[0042] The implementation principle of the wastewater treatment device of the alkali reduction machine in this application embodiment is as follows: waste pipe 11 conveys wastewater into the tank 1. At this time, the stirring motor 21 drives the stirring shaft 22 to rotate and drive the stirring blade 23 to rotate to stir and disperse the wastewater. After the dosing tank 12 adds chemicals to the wastewater in the tank 1 through the feed port 131 of the feed pipe 13, the wastewater is discharged through the drain pipe 15, and the precipitated impurities are discharged through the sludge discharge pipe 14.

[0043] When wastewater enters the tank 1, the float 51 moves as the liquid level in the tank 1 rises. Through the connecting rod 52 and the connecting rod 6, the sliding plate 41 is driven to slide, thereby adjusting the opening of the feed inlet 131. At this time, the valve cylinder 31 drives the sealing plate 32 to open, and the feeding box adds chemicals to the tank 1. After the chemical addition is completed, the sealing plate 32 closes. At this time, the stirring mechanism 2 stirs the wastewater. The float 51 drives the adjusting mechanism 4 to adjust the opening of the feed inlet 131 according to the wastewater volume, thereby adjusting the amount of chemicals added.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
