Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device used in sheep farms. Background Art

[0002] Wastewater generated during sheep farming primarily consists of feces, urine, and feed residues, typically containing organic matter, suspended solids, and nutrients such as nitrogen and phosphorus. Treatment typically begins with the removal of debris through screens and regulating tanks, followed by temporary storage. The wastewater then passes through a solid-liquid separator to separate the feces. The remaining wastewater then passes through a septic tank to decompose organic matter. Chemicals are then added to the wastewater to flocculate suspended solids. After treatment with an air flotation machine, the flocculants are scraped off, and finally, the wastewater is treated in an integrated treatment facility and disinfection tank.

[0003] The dosing device is used to put these chemicals into the mixing tank. When injecting chemicals into the sewage treatment tank, such as flocculants, disinfectants, etc., personnel are required to regularly check the remaining amount of chemicals in the dosing device to prevent insufficient chemicals from affecting the sewage treatment efficiency, which increases the workload of personnel.

[0035] Example 1

[0036] Reference Figures 1 to 8 , which is the first embodiment of the present invention, provides a sewage treatment device for a sheep farm, which includes a mixing kettle 1, including a kettle body 11, and a kettle cover 12 arranged on the top of the kettle body 11;

[0037] The sewage conveying unit 2 is provided inside the mixing kettle 1 and includes a tee pipe 21, a pair of valve seats 22 provided inside the tee pipe 21, and a reversing valve core 23 provided between the valve seats 22;

[0038] The medicine delivery unit 3 is sleeved on the outer wall of the tee pipe 21 and includes a medicine box 31, a first spring 32 arranged around the bottom of the medicine box 31, and a bellows 33 arranged on the lower surface of the medicine box 31;

[0039] The regulating unit 4 includes an impeller 41 disposed at the bottom of the reversing valve core 23 , an opening and closing assembly 42 disposed at the bottom of the impeller 41 , and an isolation box 43 sleeved on the outside of the opening and closing assembly 42 .

[0040] Furthermore, the kettle body 11 includes a plurality of supporting legs 111 disposed at the bottom thereof, and a plurality of receiving cylinders 112 disposed at the bottom of the inner cavity of the kettle body 11;

[0041] The opening of the three-way pipe 21 passes through and extends outside the kettle body 11 and the kettle cover 12 .

[0042] Furthermore, the three-way pipe 21 includes a liquid inlet channel 211, a liquid discharge channel 212 provided below the liquid inlet channel 211, a reflux channel 213 provided between the liquid inlet channel 211 and the liquid discharge channel 212, and a pair of support frames 214 provided inside the liquid discharge channel 212; the liquid discharge channel 212 extends laterally;

[0043] The valve seats 22 are fixed and symmetrically distributed inside the liquid inlet channel 211 and the liquid discharge channel 212 ; both sides of the outer wall of the reversing valve core 23 are in close contact with the sealing surface of the valve seat 22 .

[0044] Furthermore, the reversing valve core 23 includes a T-shaped channel 231 disposed therein, and a pair of gear rods 232 disposed on both sides of the outer wall of the reversing valve core 23 ; the gear rods 232 penetrate the outer wall of the three-way pipe 21 .

[0045] Furthermore, the medicine box 31 includes a dosing tube 311 arranged on the top thereof, a plurality of piston rods 312 arranged at the bottom of the medicine box 31, a notch 313 arranged on one side of the medicine box 31, racks 314 arranged on both side walls of the notch 313, and a medicine delivery port 315 arranged at the bottom of the medicine box 31.

[0046] Furthermore, the impeller 41 includes a transmission rod 411 disposed at the center thereof; the opening and closing assembly 42 is fixedly connected to the bottom of the transmission rod 411 .

[0047] Furthermore, the opening and closing assembly 42 includes an adjusting disk 421, an adjusting port 422 extending through the middle of the adjusting disk 421, adjusting blocks 423 disposed on both sides of the adjusting port 422, and a second spring 424 disposed at one end of the adjusting block 423.

[0048] The adjustment plate 421 includes a connecting frame 4211 provided on its surface, and a plurality of limiting bars 4212 provided between the connecting frames 4211;

[0049] The adjusting block 423 includes a limiting slot 4231 disposed at the bottom thereof.

[0050] Furthermore, the isolation box 43 includes a delivery port 431 arranged at its bottom, and an inlet pipe 432 arranged on the side wall of the isolation box 43; the adjustment disk 421 is attached to the bottom of the inner cavity of the isolation box 43; and the transmission rod 411 penetrates into the interior of the isolation box 43.

[0051] It should be noted that the mixing kettle 1 contains a sewage conveying unit 2 and a drug conveying unit 3, and the sewage and the drug are mixed by the regulating unit 4 and sent to the next process, such as flocculation, disinfection, etc. The kettle body 11 is cylindrical, and at least three supporting legs 111 are fixed to the bottom of the kettle body 11, which can support the entire sewage treatment device. At least one accommodating cylinder 112 is also fixed to the bottom of the inner cavity of the mixing kettle 1, and there are three in this embodiment. A first spring 32 is installed inside the accommodating cylinder 112, and the upper end of the first spring 32 is in contact with the piston rod 312 fixed at the bottom of the drug box 31. The accommodating cylinder 112 is inserted below the rod body of the piston rod 312, forming a cylinder-like structure between the two, which can prevent the drug box 31 from dislocating from the top. It should be noted that the number and position of the piston rod 312 are consistent with the accommodating cylinder 112.

[0052] When medicine is poured into the medicine box 31, the first spring 32 is in different compression states as the weight changes. In particular, as the medicine is continuously used, the first spring 32 will continuously support the medicine box 31 due to the continuous reduction of medicine, so that the liquid level of the medicine can be maintained at the same height. Therefore, when the medicine is transported to the sewage, the pressure of the liquid when it flows out is in a relatively stable state.

[0053] Preferably, the kettle cover 12 is fixed to the opening of the kettle body 11 by bolts, which can protect and support the components inside the mixing kettle 1.

[0054] Preferably, the tee 21 is T-shaped, with two intersecting channels. The top one is the inlet channel 211, which is used to input sewage, and the bottom one is the outlet channel 212, which is used to discharge sewage. Extending laterally from the side of the tee 21 is a return channel 213. When the inlet channel 211 and the outlet channel 212 are disconnected, the sewage can return to the original tank through the return channel 213. This prevents untreated sewage from mixing with the tank, affecting the ratio of the sewage to the chemical, and thus compromising the effectiveness of sewage treatment.

[0055] In addition, in order to facilitate the input and output of chemicals and sewage, the liquid inlet channel 211 passes through the kettle cover 12 from the top, the liquid discharge channel 212 passes through the bottom of the kettle body 11, and the reflux channel 213 passes through the side wall of the kettle body 11.

[0056] A pair of support frames 214 are fixed to the inner wall of the tee pipe 21 at the position of the drainage channel 212. There are through holes in the centers of the two support frames 214, and the impeller 41 can be inserted between the two. Specifically, the transmission rod 411 passes through the center of the impeller 41 and is fixed to it, and the head and tail ends of the transmission rod 411 are respectively inserted into the through holes in the centers of the support frames 214. When sewage flows through the impeller 41, the impeller 41 will rotate accordingly. When the sewage flow rate changes, the speed of the impeller 41 will also increase or decrease accordingly.

[0057] Preferably, a valve seat 22 is fixed at the intersection of the two channels in the tee pipe 21 . The two valve seats 22 are symmetrically distributed and fixed on the inner wall of the lower end of the liquid inlet channel 211 and the inner wall of the upper end of the liquid discharge channel 212 , respectively.

[0058] A spherical reversing valve core 23 is mounted between the two valve seats 22, with its outer wall contacting the sealing end of the valve seat 22. A T-shaped channel 231 is defined within the reversing valve core 23, similar in structure to the interior of the tee 21. As the reversing valve core 23 rotates, the initial state of the channel connecting the inlet channel 211 and the outlet channel 212 changes to a state of connecting the inlet channel 211 and the return channel 213.

[0059] A pair of gear rods 232 are fixed on both sides of the reversing valve core 23. The two gear rods 232 are symmetrically distributed with respect to the plane of the T-shaped channel 231. The two gear rods 232 can pass through the side wall of the tee pipe 21. Specifically, the position where the gear rods 232 pass through the intersection of the two intersecting channels.

[0060] Preferably, the medicine box 31 is cylindrical with a notch 313, which can accommodate the medicine. A dosing tube 311 is fixed to the top of the medicine box 31, which communicates with the interior of the medicine box 31. When the medicine is insufficient, the dosing tube 311 can be poured into the dosing tube 311 for replenishment. It should be noted that the dosing tube 311 extends through the kettle cover 12 to the outside. When the medicine box 31 moves axially along the receiving tube 112, the dosing tube 311 also moves with it.

[0061] Preferably, the dosing tube 311 can be a hose.

[0062] A notch 313 is defined on one side of the medicine box 31. In this embodiment, the notch 313 is waist-shaped, allowing the center of the medicine box 31 to pass through the tee 21 without being obstructed by the return channel 213 when the medicine box 31 moves axially along the accommodating tube 112. The sidewalls of the waist-shaped notch 313 are flat and parallel to each other. Racks 314 are fixed to both sidewalls near the gear rod 232. The racks 314 mesh with the teeth on the adjacent gear rod 232. When the medicine box 31 moves axially along the accommodating tube 112, it drives the reversing valve core 23 to rotate, thereby switching the internal channel of the tee 21.

[0063] It should be noted that different heights of the rack 314 can be used to set the trigger point for the remaining amount of medicine. When the threshold is reached, the reversing valve core 23 rotates, completing the switching of the channel of the three-way pipe 21. The blank area where the gear rod 232 is located is used to prevent the medicine from driving the reversing valve core 23 to rotate before the trigger point is reached.

[0064] Preferably, a medicine delivery port 315 is fixed at the bottom of the medicine box 31 , and the interior of the medicine delivery port 315 is connected to the inner cavity of the medicine box 31 , and one end of the bellows 33 is connected to the medicine delivery port 315 , so that the medicine can enter the isolation box 43 through the bellows 33 .

[0065] Preferably, inside the drainage channel 212, an isolation box 43 is provided directly below the two support frames 214. The isolation box 43 is cylindrical and can isolate the medicine to prevent contamination. Its side wall is fixed to the inner wall of the drainage channel 212 by a connecting rod, and the inlet pipe 432 is fixed on the outer wall facing the medicine delivery port 315. The inner wall of the inlet pipe 432 is connected to the inner cavity of the isolation box 43. It should be noted that the outer end of the inlet pipe 432 passes through the outer wall of the drainage channel 212 and extends to the medicine delivery port 315, while the other end of the bellows 33 is fixedly connected to the pipe mouth of the inlet pipe 432. Therefore, the medicine will flow into the interior of the isolation box 43, and the bellows 33 can expand and contract with the movement of the medicine box 31.

[0066] A through delivery port 431 is provided at the bottom of the isolation box 43 , through which the medicine inside the isolation box 43 flows into the drainage channel 212 and is fully mixed with the sewage inside the drainage channel 212 .

[0067] Preferably, at least two connecting frames 4211 distributed in opposite directions are fixed at the edge of the upper end surface of the adjusting disk 421. In this embodiment, there are four connecting frames 4211 distributed circumferentially. The connecting frames 4211 are in the shape of an L-shaped handle. Each connecting frame 4211 points to the center of the adjusting disk 421 and is connected to each other at the center position. The transmission rod 411 at the bottom of the impeller 41 is fixed to the connection center of the connecting frame 4211. When the impeller 41 rotates, the adjusting disk 421 will also rotate accordingly.

[0068] It should be noted that the lower end surface of the adjustment disk 421 is in contact with the bottom of the inner cavity of the isolation box 43 .

[0069] An adjustment opening 422 is also provided at the center of the adjustment disk 421, aligned with the delivery opening 431. At least two symmetrically distributed limiting bars 4212 are fixed to either side of the adjustment opening 422. In this embodiment, two limiting bars 4212 are used, both pointing toward the center of the adjustment opening 422. The limiting bars 4212 in this embodiment have a dovetail-shaped cross-section, which mates with the limiting groove 4231 provided at the bottom of the adjustment block 423. Therefore, the limiting groove 4231 also has a dovetail shape. One adjustment block 423 corresponds to one limiting bar 4212, and the two adjustment blocks 423 can precisely block the adjustment opening 422.

[0070] A second spring 424 is also fixed between the regulating block 423 and the longitudinal bar of the limiting bar 4212, so that the two regulating blocks 423 are tightly attached to each other and block the regulating port 422. When the impeller 41 rotates, the regulating disk 421 also rotates, and the regulating block 423 overcomes the force of the second spring 424 and opens through centrifugal force. The speed of rotation determines the magnitude of the centrifugal force, thereby controlling the opening of the regulating port 422 and then adjusting the flow rate of the outflow of the medicine.

[0071] In summary, the greater the sewage flow rate, the greater the discharge flow rate of the agent, and vice versa. As the agent is consumed, the lighter the agent tank 31 becomes, allowing the first spring 32 to gradually lift the agent tank 31. During this process, the agent level remains relatively stable, meaning that the pressure level of the discharged agent fluctuates minimally, thus laying the foundation for approximately proportional changes in the sewage flow rate and the agent flow rate.

[0072] When the medicine is consumed to a certain extent, the rack 314 on the medicine box 31 can contact the gear rod 232, and then as the consumption increases further, the reversing valve core 23 will rotate slowly until sewage flows into the reflux channel 213. At this time, the sewage flow rate becomes smaller and the medicine flow rate also becomes smaller. Personnel should pay attention to the sewage flowing out of the reflux channel 213, which indicates that medicine needs to be added.

[0073] After the chemicals are added, the chemicals box 31 will drop, so that the reversing valve core 23 can rotate, thereby allowing the sewage to enter the drainage channel 212 normally.

[0074] Preferably, the shape of the medicine box 31 can also be square, conical, etc., which can be determined according to actual needs.

[0075] It's important to further clarify that the rotation of impeller 41 driven by sewage is directly linked to adjustment block 423, which controls the flow area for the reagent. Therefore, changes in the speed of impeller 41 are directly reflected in changes in the flow area for the reagent. There is a linear relationship between the speed of impeller 41 and the sewage flow rate, and between the speed of impeller 41 and the flow area for the reagent. Changes in sewage flow rate result in proportional changes in the speed of impeller 41, and thus in proportional changes in the flow area for the reagent.

[0076] Assuming that the reduction in sewage flow leads to a reduction in the speed of the impeller 41, if there is a linear relationship between the speed of the impeller 41 and the sewage flow, it can be expressed as:

[0077]

[0078] in: is the impeller speed; is the flow rate of sewage; is the proportionality constant.

[0079] If there is also a linear relationship between the rotation speed of the impeller 41 and the flow area of ​​the reagent, it can be expressed as:

[0080]

[0081] in: is the circulation area of ​​the agent; is the proportionality constant.

[0082] Combining these two equations, we can get the relationship between the reagent flow area and sewage flow:

[0083]

[0084]

[0085] in is the new constant of proportionality.

[0086] Flow rate of medicine and circulation area and the average flow rate of the drug related:

[0087]

[0088] If the flow rate of the drug remains constant (e.g., at a constant pressure), then the flow rate of the agent will be related to the circulation area is proportional to the flow rate of sewage Directly proportional.

[0089] In summary, the present invention can promptly adjust the flow rate of the reagent delivery when the sewage flow rate changes, maintaining a stable sewage-to-drug ratio. Furthermore, without the need for a pump, the delivery pressure can be stabilized even if the reagent level decreases. When the residual reagent reaches a certain threshold, the sewage delivery action can be changed to remind the operator to replenish the reagent in a timely manner.

[0090] It is important to note that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. 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.
