Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and particularly to a harmless wastewater treatment device based on the spice production process. Background Art

[0002] Spice wastewater refers to the wastewater generated during the production and use of spices. This type of wastewater usually contains high levels of organic matter, biodegradable substances, microorganisms, and may also contain a small amount of heavy metals, organic pollutants, etc., and must be harmlessly treated before discharge.

[0003] The main treatment process of spice wastewater includes steps such as pretreatment, biological treatment, advanced treatment, and wastewater discharge. Usually, physical treatment and chemical treatment are carried out on the wastewater in the pretreatment stage. The main purpose of these two types of treatments is to remove suspended solids, oil pollutants, and other organic substances that are difficult to biologically treat in the wastewater, and reduce the concentrations of pollutants such as suspended solids, turbidity, and oil in the wastewater. Common physical treatment methods include grille slag removal, flotation, etc., and common chemical treatment methods include pH adjustment, coagulation and flocculation, and oxidation treatment. Among them, coagulation and flocculation treatment uses chemical agents (such as polyaluminum chloride, polyacrylamide, etc.) to chemically flocculate the wastewater to form large flocs, which is convenient for subsequent sedimentation and biochemical treatment. When the wastewater after advanced treatment meets the national and local discharge standards, it can be discharged into the municipal sewage pipe network or directly into the water body.

[0004] When the existing spice wastewater treatment device performs coagulation and flocculation treatment on the wastewater, usually during the flowing process of the wastewater after impurity removal and screening, the flocculant is directly sprayed onto the surface of the wastewater through a nozzle to naturally mix and flocculate with the wastewater. During this process, the mixing process of the flocculant and the wastewater is relatively slow, unable to quickly mix with the wastewater, and the mixing is insufficient and uneven, unable to quickly generate flocs, thereby reducing the efficiency of subsequent sedimentation treatment. And it cannot adaptively adjust the change of the coagulant discharge amount according to the flow rate and pressure of the wastewater, with insufficient adaptability, resulting in poor mixing effect of the flocculant. Summary of the Invention

[0005] In view of the problems in the prior art that the mixing of the flocculant and the wastewater is insufficient and uneven, and the mixing effect is poor, a harmless wastewater treatment device based on the spice production process is thus proposed.

[0006] Its purpose is to: increase the contact area between the flocculant and the wastewater, enhance the mixing effect, and adaptively adjust the amount of the coagulant discharged according to the flow rate and pressure of the wastewater, improving the efficiency of mixing and flocculation.

[0007] The technical solution of the present invention is a harmless treatment device for wastewater in a spice production process, comprising a screening pretreatment device and a sedimentation tank arranged at one end of the screening pretreatment device, and also comprising a mixing unit arranged between the screening pretreatment device and the sedimentation tank;

[0008] The mixing unit comprises a connecting pipe disposed between the screening pretreatment device and the settling tank, a conveying pipe disposed at the top of the connecting pipe and extending into the interior of the connecting pipe, a discharging component disposed inside the conveying pipe, and a mixing component disposed on one side of the discharging component;

[0009] The discharging component is used to control the output of the mixed agent, and the mixing component is used to discharge and mix the output mixed agent into wastewater;

[0010] The discharging component includes an opening and closing component arranged at one side of the bottom of the conveying pipe, an opening and closing control component arranged at the middle of the opening and closing component, and a toggle component arranged at one side of the opening and closing control component;

[0011] The opening and closing assembly includes an opening and closing cavity opened inside one end of the bottom of the conveying pipe, a rotating plate arranged in the opening and closing cavity, a plurality of driving holes opened on the rotating plate in a ring array, driving rods respectively arranged in the plurality of driving holes, an opening and closing plate arranged on the driving rod, a fixed rod arranged at the other end of the opening and closing plate, and one side of the fixed rod is fixedly connected to the cavity wall of the opening and closing cavity, a torsion spring arranged between the fixed rod and the opening and closing plate, a rotating ring arranged on one side of the rotating plate, and the rotating ring is rotatably arranged inside the conveying pipe, a driving rod arranged on one side of the rotating ring, and a rotating hole opened in the conveying pipe for the driving rod to move, and one side of the driving rod extends through the rotating hole to the inner cavity of the conveying pipe.

[0012] Furthermore, the plurality of opening and closing plates of the annular array form a complete circle, and a circular hole is formed in the middle thereof for the opening and closing control component to pass through.

[0013] Furthermore, the opening and closing control assembly includes a control rod arranged in the middle of the plurality of opening and closing plates, a driving tooth arranged at one end of the control rod, a sliding frame arranged on the side of the control rod away from the driving tooth, and the sliding frame is arranged on the inner wall of the conveying pipe, a tension spring arranged on one side of the sliding frame and sleeved on the control rod, and a limiting ring arranged on one side of the tension spring, and the limiting ring is connected to a limited position and rotation inside the driving tooth.

[0014] Furthermore, the toggle assembly includes a support rod arranged inside the conveying tube, a support frame arranged at one end of the support rod, a driven tooth arranged at one side of the support frame, and a toggle rod arranged on the side wall of the driven tooth.

[0015] Furthermore, the shape of the toggle rod is L-shaped, and the driving teeth and the driven teeth are not concentric.

[0016] Furthermore, the mixing component includes a rotating end sealed on one side of the conveying pipe, and one side of the control rod is fixedly connected to the inner wall of the rotating end, a ring array of mixing blades is arranged on one side of the rotating end, a linear array of discharge holes is opened on one side of the mixing blade, and a plurality of discharge holes are connected to the inner cavity of the rotating end.

[0017] Furthermore, the mixing component also includes a stirring blade arranged on the other side of the conveying pipe.

[0018] Furthermore, the mixing blade and the stirring blade have opposite blade inclinations.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When the wastewater pressure and flow rate are greater, the mixing blade drives the driving teeth to rotate faster, which makes the toggle lever toggle the push lever faster, and eventually the toggle lever will continue to toggle the push lever, so that the opening and closing plate is in a fully open state, maximizing the coagulant flow rate. This setting can adaptively control the discharge speed and discharge amount of the coagulant according to the flow rate and pressure of the wastewater, so that under the condition of the same cross-section of the connecting pipe, the faster the flow rate of the wastewater, the more coagulant can be adaptively mixed, which improves the mixing efficiency of the coagulant and wastewater and enhances the subsequent sedimentation effect.

[0021] 2. The mixing blades and stirring blades are set in opposite directions, so that the wastewater flowing through the mixing blades can deflect the flow direction when passing through the stirring blades, so that the coagulant can change the direction of flow mixing in the wastewater, thereby achieving a better mixing effect of the coagulant, which not only realizes the full mixing of the coagulant in the water, but also realizes the ability to adaptively adjust the amount of coagulant discharged according to the wastewater flow rate and pressure, thereby achieving full and uniform mixing of the wastewater and the coagulant.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0035] Example 1, reference Figures 1 - 10, which is the first embodiment of the present invention, provides a wastewater harmless treatment device based on the spice production process, including a screening pretreatment device 1 and a sedimentation tank 2 arranged at one end of the screening pretreatment device 1, and also includes a mixing unit installed between the screening pretreatment device 1 and the sedimentation tank 2; the mixing unit includes a connecting pipe 3 connected between the screening pretreatment device 1 and the sedimentation tank 2, a conveying pipe 4 fixedly connected to the top of the connecting pipe 3 and extending into the connecting pipe 3, a discharging component installed in the conveying pipe 4, and a mixing component 8 installed on one side of the discharging component; the discharging component is used to control the output of the mixture, and the mixing component 8 is used to discharge the output mixture into the wastewater; the discharging component includes an opening and closing component 5 installed on one side of the bottom of the conveying pipe 4, an opening and closing control component 6 installed in the middle of the opening and closing component 5, and a toggle component 7 installed on one side of the opening and closing control component 6; the opening and closing component 5 It includes an opening and closing cavity 51 opened inside one end of the bottom of the conveying pipe 4, a rotating plate 52 rotatably connected to the opening and closing cavity 51, a plurality of driving holes 53 opened in a ring array on the rotating plate 52, driving rods 54 respectively slidably connected to the plurality of driving holes 53, an opening and closing plate 55 rotatably connected to the driving rod 54, a fixed rod 56 rotatably connected to the other end of the opening and closing plate 55, and one side of the fixed rod 56 is fixedly connected to the cavity wall of the opening and closing cavity 51, a torsion spring (playing a torsional reset role, not shown in the figure) abutting between the fixed rod 56 and the other end of the opening and closing plate 55, a rotating ring 57 fixedly connected to one side of the rotating plate 52, and the rotating ring 57 is rotatably connected to the inside of the conveying pipe 4, a pushing rod 58 fixedly connected to one side of the rotating ring 57, and a rotating hole 59 opened in the conveying pipe 4 for the pushing rod 58 to rotate, and one side of the pushing rod 58 extends to the inner cavity of the conveying pipe 4 through the rotating hole 59.

[0036] Specifically, when treating wastewater in the spice production process, the wastewater is first pretreated by a screening pretreatment device 1. Screening pretreatment can be performed by screening and centrifugation. Screening can be filtered through a screen to remove larger solid particles. Centrifugation can use centrifugal force to separate emulsions with larger density and further remove suspended particles in the wastewater. After removing the suspended particles, a coagulant is added to the wastewater to form large flocs in the wastewater, which is convenient for subsequent sedimentation in the sedimentation tank 2. The coagulant is mixed into the wastewater through a mixing unit so that the coagulant and the wastewater are fully mixed and reacted. The delivery pipe 4 delivers the coagulant to the connecting pipe 3 through a pressure pump. The wastewater is mixed with the coagulant when passing through the connecting pipe 3 and then enters the sedimentation tank 2. The opening and closing assembly 5 is used to control the opening and closing of the inside of the delivery pipe 4 and the size of the opening and closing, so as to control the flow rate of the coagulant discharged. In the initial state, the opening and closing plates 55 form a complete circle under the force of the torsion spring and block the delivery pipe 4, so that the coagulant cannot be discharged. When the opening and closing control assembly 6 toggles the opening and closing assembly 5 through the toggle assembly 7, the push rod 58 in the opening and closing assembly 5 is toggled to rotate counterclockwise in the rotating hole 59, driving the rotating ring 57 and the rotating plate 52 to rotate counterclockwise, and the rotating plate 5 When rotating, the driving rod 54 on one side of the opening and closing plate 55 is pushed to rotate through the driving hole 53. Since the fixing rod 56 limits one side of the opening and closing plate 55, the rotating plate 52 drives the opening and closing plate 55 to rotate when rotating, that is, the delivery pipe 4 is opened. When the driving rod 54 rotates to the end of the driving hole 53, the delivery pipe 4 is fully opened. That is, the rotation amplitude of the rotating plate 52 is proportional to the opening amplitude of the delivery pipe 4. That is, the larger the rotation amplitude of the rotating plate 52 and the longer the time, the more coagulant flows.

[0037] Reference Figure 5 The plurality of opening and closing plates 55 of the annular array form a complete circle, and a circular hole is formed in the middle thereof for the opening and closing control component 6 to pass through.

[0038] Specifically, the formed complete circle can seal the inside of the conveying pipe 4, so that when no wastewater passes through the connecting pipe 3, the coagulant is not discharged. When wastewater passes through the connecting pipe 3, the pressure of the water pushes the mixing component 8 and causes the mixing component 8 to rotate counterclockwise, so that the mixing component 8 can open the discharge component and put the coagulant into the wastewater for a mixing reaction.

[0039] Reference Figures 7 - 8The opening and closing control assembly 6 includes a control rod 61 slidably connected to the middle of the plurality of opening and closing plates 55, a driving tooth 62 fixedly connected to one end of the control rod 61, a sliding frame 63 rotatably connected to the side of the control rod 61 away from the driving tooth 62, and the sliding frame 63 is fixedly connected to the inner wall of the conveying pipe 4, a tension spring 64 fixedly connected to one side of the sliding frame 63 and sleeved on the control rod 61, and a limiting ring 65 fixedly connected to one side of the tension spring 64, and the limiting ring 65 is rotationally connected to limit the position inside the driving tooth 62.

[0040] Specifically, the opening and closing control component 6 is used to drive the toggle component 7 to open the opening and closing component 5. When the wastewater is discharged through the connecting pipe 3 and enters the sedimentation tank 2, when the wastewater flows through the connecting pipe 3, the water pressure pushes the mixing component 8 and drives it to rotate counterclockwise, so that the control rod 61 moves synchronously and rotates counterclockwise. The control rod 61 moves toward one side of the toggle component 7 on the sliding frame 63 and pushes the driving tooth 62 on one side to move together. During the movement, the driving tooth 62 pulls the tension spring 64 through the limit ring 65, and finally engages with the toggle component 7, driving the toggle component 7 to rotate counterclockwise, thereby driving the push rod 58 in the opening and closing component 5 to rotate synchronously counterclockwise, and the opening and closing plate 55 rotates and opens synchronously, so that the pressurized coagulant inside the conveying pipe 4 can be discharged, and the coagulant is discharged from the mixing component 8; when the wastewater no longer flows through the connecting pipe 3 or the wastewater is about to be discharged, the mixing component 8 stops rotating or only idles, and the opening and closing plate 55 is no longer opened, so that the coagulant will not be discharged, thereby avoiding waste and excessive addition of coagulant.

[0041] Reference Figure 9 The toggle assembly 7 includes a support rod 71 fixedly connected to the inside of the conveying pipe 4, a support frame 72 limitedly rotatably connected to one end of the support rod 71, a driven tooth 73 fixedly connected to one side of the support frame 72, and a toggle rod 74 fixedly connected to the side wall of the driven tooth 73.

[0042] Specifically, when the driving tooth 62 is pushed, the driving tooth 62 meshes with the driven tooth 73, synchronously driving the driven tooth 73 to rotate, and the driven tooth 73 drives the toggle rod 74 to rotate, and the toggle rod 74 drives the push rod 58 to rotate, so that the rotating ring 57 drives the opening and closing plate 55 to rotate, thereby opening the conveying pipe 4 so that the coagulant can be discharged, and the support rod 71 supports the rotation of the support frame 72.

[0043] Reference Figures 9 - 10 The shape of the toggle rod 74 is L-shaped, and the driving tooth 62 and the driven tooth 73 are not concentric.

[0044] Specifically, the non-concentric arrangement of the driving tooth 62 and the driven tooth 73, that is, the eccentric arrangement of the driven tooth 73, makes it easy for the driving tooth 62 to drive the driven tooth 73 to rotate synchronously, and the toggle rod 74 can realize intermittent toggle and disengagement of the push rod 58, thereby realizing intermittent opening of the conveying tube 4.

[0045] Example 2, reference Figures 1 - 4 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: the mixing component 8 includes a rotating end 81 that is sealed and rotatably connected to one side of the delivery pipe 4, and one side of the control rod 61 is fixedly connected to the inner wall of the rotating end 81, an annular array of mixing blades 82 is fixedly connected to one side of the rotating end 81, and a linear array of discharge holes 83 are opened on one side of the mixing blades 82, and a plurality of discharge holes 83 are communicated with the inner cavity of the rotating end 81.

[0046] Specifically, when wastewater passes through the connecting pipe 3, the pressure of the wastewater drives the mixing blade 82 to rotate counterclockwise, and at the same time, it also drives the entire rotating end 81 and the control rod 61 to move toward the side of the toggle assembly 7, and the tension spring 64 is stretched, so that the driving tooth 62 and the driven tooth 73 are engaged, so that the toggle rod 74 toggles the push rod 58, thereby driving the opening and closing plate 55 to open the delivery pipe 4, and when the water pressure is greater and the flow rate is faster, the rotating end 81 drives the control rod 61 to rotate faster, so that the speed of the toggle rod 74 toggling the push rod 58 is faster. When the toggle rod 74 rotates and toggles one side of the push rod 58, the opening and closing plate 55 will be reset and rotated under the reset force of the torsion spring, so that the push rod 58 will also be reset and rotated. If the toggle rod 74 toggles the push rod 58 faster and more frequently, the time for the opening and closing plate 55, the rotating ring 57 and the push rod 58 to reset will be gradually compressed, so that the longer the opening and closing plate 55 is opened, the larger the space for the coagulant to pass through, and the more the amount of circulation, so that more coagulant is sprayed out from the discharge hole 83 to mix with the wastewater. When the wastewater pressure is greater and the flow rate is greater, the mixing blade 82 drives the driving tooth 62 to rotate faster, so that the toggle rod 74 toggles the push rod 58 faster, and finally the toggle rod 74 will continue to toggle the push rod 58, so that the opening and closing plate 55 is in a fully open state, realizing the maximization of the coagulant flow rate. Such an arrangement makes it possible to adaptively control the discharge speed and amount of the coagulant according to the flow rate and pressure of the wastewater, so that under the condition of the same cross-section of the connecting pipe 3, wastewater with a faster flow rate can be adaptively mixed with more coagulant, thereby improving the mixing efficiency of the coagulant and wastewater and enhancing the subsequent sedimentation effect.

[0047] Reference Figures 1 - 3 The mixing component 8 also includes a stirring blade 84 rotatably connected to the other side of the conveying pipe 4.

[0048] Specifically, the coagulant discharged from the discharge hole 83 can be rotationally mixed into the wastewater flowing through, and then the coagulant can be more fully mixed with the wastewater through the rotation and stirring of the stirring blade 84 on the other side.

[0049] Reference Figure 3 , the mixing blade 82 and the stirring blade 84 have opposite blade deflections.

[0050] Specifically, the blades are arranged in opposite directions, so that the wastewater flowing through the mixing blades 82 can be deflected when passing through the stirring blades 84, so that the coagulant can change the direction of flow and mixing in the wastewater, achieving a better mixing effect of the coagulant. The rest of the structure is the same as that of Example 1.

[0051] Based on Examples 1-2, the working principle of the present invention is as follows: when the wastewater is flocculating, it flows through the connecting pipe 3, and the mixing blade 82 is pushed to rotate counterclockwise under the pressure of the wastewater and is pushed to move toward the stirring blade 84, and the control rod 61 pushes the driving tooth 62 to move and meshes with the driven tooth 73 for transmission, so that the driven tooth 73 drives the toggle rod 74 to toggle the push rod 58 to rotate counterclockwise, and the push rod 58 drives the rotating ring 57 and the rotating plate 52 to rotate synchronously, so that the driving rod 54 drives the opening and closing plate 55 to rotate, and the opening and closing plate 55 twists the compression torsion spring to open, so that the pressurized coagulant in the conveying pipe 4 is discharged and mixed from the discharge hole 83 of the mixing blade 82. When the wastewater pressure is greater and the water flows faster, the mixing blade 82 will drive the control rod 61 to rotate faster, so that the push rod 58 is pushed to drive the opening and closing plate 55 to open for a longer time, so that more coagulant flows through, which not only achieves sufficient mixing of the coagulant in the water, but also realizes the ability to adaptively adjust the amount of coagulant discharged according to the wastewater flow rate and pressure, thereby achieving sufficient and uniform mixing of the wastewater and the coagulant.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
