Description

Technical Field

[0001] This invention relates to the field of sludge treatment equipment technology, specifically to a municipal engineering sludge resource utilization treatment device. Background Technology

[0002] Jet aeration tank technology is widely used in the biological treatment of municipal wastewater. The technology uses a water pump to draw wastewater containing activated sludge from the aeration tank and returns it to the aeration tank in the form of a high-speed jet through nozzles. During this process, air is introduced into the activated sludge and wastewater to maintain the activity of microorganisms in the activated sludge. The microorganisms decompose the organic matter in the wastewater, thereby achieving the purpose of wastewater treatment.

[0003] For example, Chinese Patent Publication No. CN120943405A discloses a wastewater treatment system based on municipal engineering, relating to the field of wastewater treatment technology. In this invention, a suction section is located below the mixing tank, close to the bottom of the tank reaction vessel. The suction channel is used to lift the wastewater mixture from the bottom of the tank reaction vessel into the mixing tank. The return section is used to transport the aerated wastewater mixture into the tank reaction vessel. The return channel is slidably fitted inside the corresponding suction channel. The jet assembly is interconnected with the return channels on both sides, and the jet assembly is used to spray the wastewater mixture in the return channel into the tank reaction vessel in the form of a jet.

[0004] The cited document states that by controlling the lifting and lowering movement of the support ring and the guide pipe between different jet points, the sludge mixed with wastewater at the bottom of the pool can be extracted and transported to be dispersed into the wastewater at different jet points, thereby achieving full diffusion of oxygen-containing activated sludge in the wastewater to improve the pollutant degradation effect.

[0005] However, in the aforementioned cited documents, when aerating the wastewater in the treatment tank, the sludge in the wastewater will settle and accumulate at the bottom of the treatment tank, resulting in a small contact area between the aeration and the sludge in the wastewater. Furthermore, when adding multiple agents to the treatment tank for purification, the operation process of manually switching and adjusting the connecting pipes is cumbersome and prone to errors, making it difficult to achieve automated and precise control of agent addition. Summary of the Invention

[0006] The purpose of this invention is to provide a municipal engineering sludge resource utilization treatment device, which can achieve efficient disturbance and aeration uniformity improvement of the sludge settled at the bottom of the treatment tank, as well as automated and precise switching control of the addition of various agents, so as to solve the problems of small aeration contact range and cumbersome and error-prone operation of agent addition in the prior art.

The synchronous one-way component includes a one-way ratchet, and ratchet teeth are evenly meshed on the outer circumference of the one-way ratchet.

[0008] Preferably, a sealed box is fixedly installed on the top of the treatment box, an inlet pipe is fixedly connected to one side of the treatment box, an outlet pipe is fixedly connected to the bottom of the treatment box, and the ends of multiple sets of drug inlet pipes and connecting pipes respectively extend movably through to the outside of the sealed box.

[0009] Preferably, a first bracket is fixedly installed on the top of the aeration pipe, the rodless cylinder base is fixedly installed on the inner wall of the treatment tank, and the end of the first bracket is fixedly installed on the movable end of the rodless cylinder.

[0010] Preferably, a spiral path groove is provided between the positioning rod and the positioning sleeve, the positioning sleeve is slidably installed between the positioning rod and the positioning sleeve through the spiral path groove, and a positioning baffle is fixedly installed at the top of the positioning rod.

[0011] Preferably, multiple sets of second supports are fixedly installed on the top of the inner wall of the treatment box, and the positioning tube is rotatably installed at the center of the bottom of the multiple sets of second supports. A metering pump is fixedly installed on the outer ring surface of the end of the drug inlet tube away from the drug filling tank. The metering pump is used to draw the corresponding drug from the outer end of the drug inlet tube into the inside of the drug filling tank.

[0012] Preferably, a support is fixedly installed on one side of the outside of the medicine tank, a connecting shaft is rotatably connected to the top of the support, the positioning plate is fixedly installed at the top of the connecting shaft, and a pin is fixedly installed at the bottom circumferential edge of the positioning plate.

[0013] Preferably, the top circumference of the adjusting seat is provided with equally spaced pin grooves, and each group of symmetrically distributed pin grooves is located on the circumferential path of the pin shaft rotation.

[0014] Preferably, an annular plate is fixedly installed at the bottom of the adjusting seat. The annular plate is in contact with the inner wall of the medicine tank. A connecting hole is opened through the circumference of the annular plate. The connecting hole and multiple sets of medicine inlet tubes are located on the same circumferential plane.

[0015] Preferably, the one-way ratchet is located at the top of the inner wall of the positioning tube with a clearance fit, the bottom end of the connecting shaft movably passes through the top of the positioning tube, and the connecting shaft is fixedly installed at the center of the top of the one-way ratchet. Multiple sets of the corner seats are fixedly installed at equal intervals on the top circumference of the inner wall of the positioning tube. Multiple sets of ratchet teeth are rotatably connected to multiple sets of corner seats in a one-to-one correspondence through a rotating shaft. A torsion spring is fixedly installed between the rotating shaft at the top of the ratchet teeth and the corner seat.

[0016] Preferably, the connecting nozzle extends movably through the inner wall of the treatment tank, and the bottom end of the connecting pipe extends movably through the connecting shaft and the positioning rod to the inner wall of the aeration pipe.

[0017] Compared with the prior art, the beneficial effects of the present invention are: In this invention, a connecting pipe is connected to an aeration pipe, and the other end of the connecting pipe can be connected to an external air source or aeration equipment. Air or oxygen is then delivered to the aeration pipe through the connecting pipe and released into the sludge mixture in the treatment tank through the aeration holes on the aeration pipe, providing oxygen for the microorganisms. When the rodless cylinder is activated, its movable end drives the first support to move up and down, thereby causing the aeration pipe to move vertically. This allows the gas released from the aeration holes in the aeration pipe to create a turbulent effect in the treatment tank, diffusing from the inside out. This turbulence, combined with the sludge accumulated at the bottom of the treatment tank, creates a larger aeration area within the treatment tank. This effectively disturbs any sludge that may settle at the bottom of the treatment tank, preventing sludge accumulation and significantly improving the uniformity of aeration and the contact area with the sludge, thereby enhancing the activity of the microorganisms and the decomposition efficiency of organic matter.

[0018] In this invention, when the aeration pipe moves upward, the positioning rod slides within the positioning sleeve through a spiral path groove, forcing it to rotate in the forward direction. This causes the unidirectional ratchet to rotate in one direction, which in turn rotates the positioning disc synchronously. The pin at the bottom of the positioning disc then rotates in a circular motion. When the pin reaches a certain pin groove position on the top of the adjusting seat, it embeds itself in the groove and rotates the adjusting seat by a certain angle. The annular plate at the bottom of the adjusting seat also rotates, aligning the connecting hole on the annular plate with the different drug inlet pipe ports. At this point, the corresponding metering pump starts, drawing the drug connected to the drug inlet pipe into the dosing tank through the connecting hole, and then spraying it into the treatment tank through the connecting nozzle. By controlling the rotation angle and frequency of the connecting shaft through the reciprocating upward movement of the aeration pipe, precise and automatic switching of different drugs can be achieved, avoiding the tedious operation and potential errors of manually switching pipes.

[0019] In this invention, when the aeration pipe moves downward, the positioning rod drives the positioning sleeve and positioning pipe to rotate in the opposite direction through the spiral path groove. At the same time, the corner seat on the inner wall of the positioning pipe drives the ratchet to rotate synchronously. At this time, the ratchet slides on the back of the teeth of the one-way ratchet, the torsion spring is compressed, and the one-way ratchet does not rotate. Therefore, the connecting shaft and the circulating positioning component remain stationary and no drug switching occurs. This design realizes the linkage between the lifting and lowering movement of the aeration pipe and the switching action of drug addition, so that the aeration process and the drug addition process are coordinated and linked, further improving the automation level and processing efficiency of the device operation. Multiple sets of drug inlet pipes are connected to different types of drug sources, and each drug inlet pipe is equipped with a metering pump for precise control of the amount of drug extracted. The setting of the circulating positioning component realizes the automated switching of drug addition. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. The described embodiments are only some embodiments of the present invention, and not all embodiments. Example

[0023] This embodiment provides a municipal engineering sludge resource utilization treatment device, such as... Figures 1-7 As shown, the device includes a processing box 100, and also includes: An aeration pipe 200 is installed in the inner cavity of the treatment box 100. A positioning rod 22 is fixedly installed on the top of the aeration pipe 200, and a connecting pipe 23 is movably connected inside the aeration pipe 200. Rodless cylinder 300 is installed on both sides of the inner wall of processing box 100; The positioning tube 400 is rotatably installed on the inner wall of the processing box 100 near the top. The bottom of the inner wall of the positioning tube 400 is integrally formed with a positioning sleeve 42. A dosing tank 500 is fixedly installed on the top of the treatment tank 100. Multiple sets of dosing pipes 51 are fixedly connected at equal intervals on the outer circumference of the dosing tank 500. A connecting nozzle 53 is fixedly connected to the bottom of the dosing tank 500. The treatment tank 100 has a sealed box 11 fixedly installed on the top, an inlet pipe 12 fixedly connected to one side of the treatment tank 100, and an outlet pipe 13 fixedly connected to the bottom of the treatment tank 100. Multiple sets of inlet pipes 51 and connecting pipes 23 are respectively movably extended to the outside of the sealed box 11. The connecting pipes 23 are connected to the aeration pipes 200. The other end of the connecting pipes 23 can be connected to an external air source or aeration equipment, so that air or oxygen can be transported to the aeration pipes 200 through the connecting pipes 23 and then released into the sludge mixture in the treatment tank 100 through the aeration holes on the aeration pipes 200.

[0024] The aeration pipe 200 is fixedly mounted with a first bracket 21 at the top. The base of the rodless cylinder 300 is fixedly mounted on the inner wall of the treatment tank 100. The end of the first bracket 21 is fixedly mounted on the movable end of the rodless cylinder 300. The movable end of the rodless cylinder 300 drives the first bracket 21 to move up and down, thereby driving the aeration pipe 200 to move in the vertical direction. This allows the gas released from the aeration holes in the aeration pipe 200 to generate an agitation effect in the treatment tank 100, diffuse from the inside out, and form a turbulence with the sludge accumulated at the bottom of the treatment tank 100, so that the aeration pipe 200 can form a larger aeration area in the treatment tank 100.

[0025] A spiral path groove 221 is provided between the positioning rod 22 and the positioning sleeve 42. The positioning sleeve 42 is slidably installed between the positioning rod 22 and the positioning rod 22 through the spiral path groove 221. A positioning baffle 222 is fixedly installed at the top of the positioning rod 22. Multiple sets of second brackets 41 are fixedly installed on the top of the inner wall of the treatment box 100. The positioning tube 400 is rotatably installed at the bottom center of the multiple sets of second brackets 41. A metering pump 52 is fixedly installed on the outer ring surface of the end of the inlet tube 51 away from the dispensing tank 500. The metering pump 52 is used to draw the medicine from the outer end of the corresponding inlet tube 51 into the dispensing tank 500. A support 631 is fixedly installed on one side of the outside of the dispensing tank 500. A connecting shaft 63 is rotatably connected to the top of the support 631. The positioning plate 61 is fixedly installed on the connecting shaft 631. At the top, a pin 611 is fixedly installed at the bottom circumferential edge of the positioning disc 61. Pin grooves 621 are evenly spaced on the top circumference of the adjusting seat 62. Each set of symmetrically distributed pin grooves 621 is located on the circumferential path of the pin 611. When the aeration pipe 200 moves upward, the top of the positioning rod 22 slides in the positioning sleeve 42 through the spiral path groove 221. The spiral path groove 221 forces the positioning rod 22 to rotate in the forward direction. Since multiple sets of ratchet teeth 72 on the circumference of the positioning tube 400 mesh with the one-way ratchet 71, the one-way ratchet 71 can rotate in one direction, thereby causing the connecting shaft 63 to drive the positioning disc 61 to rotate synchronously. The pin 611 at the bottom of the positioning disc 61 then makes a circular motion.

[0026] In this embodiment, the connecting pipe 23 is connected to the aeration pipe 200. The other end of the connecting pipe 23 can be connected to an external air source or aeration equipment, thereby delivering air or oxygen to the aeration pipe 200 through the connecting pipe 23, and then releasing it into the sludge mixture in the treatment tank 100 through the aeration holes on the aeration pipe 200, providing oxygen for the microorganisms. When the rodless cylinder 300 is started, its movable end drives the first support 21 to move up and down, thereby driving the aeration pipe 200 to move vertically. This allows the gas released from the aeration holes in the aeration pipe 200 to generate an agitation effect in the treatment tank 100, diffusing from the inside out, and forming turbulence with the sludge accumulated at the bottom of the treatment tank 100. This allows the aeration pipe 200 to form a larger aeration area in the treatment tank 100, effectively disturbing the sludge that may settle at the bottom of the treatment tank 100, preventing sludge accumulation, significantly improving the uniformity of aeration and the contact area with the sludge, and enhancing the activity of microorganisms and the decomposition efficiency of organic matter.

[0027] In this embodiment, when the aeration pipe 200 moves upward, the top of the positioning rod 22 slides within the positioning sleeve 42 through the spiral path groove 221, and the spiral path groove 221 forces the positioning rod 22 to rotate in the forward direction. Since multiple sets of ratchet teeth 72 on the circumference of the positioning pipe 400 mesh with the one-way ratchet 71, the one-way ratchet 71 can rotate in one direction, thereby causing the connecting shaft 63 to drive the positioning disk 61 to rotate synchronously. The pin 611 at the bottom of the positioning disk 61 then makes a circular motion. When the pin 611 moves to a certain pin groove 621 position on the top of the adjusting seat 62, it will be embedded in the pin groove 621 and drive the adjusting seat 62 to rotate at a certain angle. The annular plate 622 at the bottom of the adjusting seat 62 also rotates, so that the connecting hole 623 on the annular plate 622 is aligned with the port of the different drug inlet pipe 51. At this time, the corresponding metering pump 52 starts, and the agent connected to the inlet pipe 51 is drawn into the dosing tank 500 through the connecting hole 623. Then, it is sprayed into the treatment tank 100 through the connecting nozzle 53. By moving the aeration pipe 200 upwards and reciprocating each time, the rotation angle and frequency of the connecting shaft 63 can be controlled, so as to achieve precise and automatic switching and addition of different agents, avoiding the tedious operation of manually switching pipelines and the possible errors. Example

[0028] Based on Example 1, this embodiment provides a municipal engineering sludge resource utilization treatment device, such as... Figures 3-7 As shown, Includes: a circulation positioning assembly 600, which is installed on the top of the medicine tank 500. The circulation positioning assembly 600 includes a positioning plate 61 and an adjusting seat 62, which is rotatably installed on the top of the medicine tank 500. The synchronous one-way component 700 is installed at the bottom of the cyclic positioning component 600. The synchronous one-way component 700 includes a one-way ratchet 71, and ratchet teeth 72 are evenly meshed on the outer circumference of the one-way ratchet 71.

[0029] The bottom of the adjusting seat 62 is fixedly equipped with an annular plate 622, which fits against the inner wall of the medicine tank 500. A connecting hole 623 is opened through the circumference of the annular plate 622. The connecting hole 623 and multiple sets of medicine inlet tubes 51 are located on the same circumferential plane. When the pin 611 moves to a certain pin groove 621 position on the top of the adjusting seat 62, it will be embedded in the pin groove 621 and drive the adjusting seat 62 to rotate a certain angle. The annular plate 622 at the bottom of the adjusting seat 62 will also rotate accordingly, so that the connecting hole 623 on the annular plate 622 is aligned with the port of different medicine inlet tubes 51.

[0030] The one-way ratchet 71 is located at the top of the inner wall of the positioning tube 400 with a clearance fit. The bottom end of the connecting shaft 63 moves through the top of the positioning tube 400, and the connecting shaft 63 is fixedly installed at the center of the top of the one-way ratchet 71. Multiple sets of corner seats 721 are fixedly installed at equal intervals on the top circumference of the inner wall of the positioning tube 400. Multiple sets of ratchet teeth 72 are rotatably connected to the multiple sets of corner seats 721 through a rotating shaft. A torsion spring 722 is fixedly installed between the rotating shaft at the top of the ratchet teeth 72 and the corner seat 721. The connecting nozzle 53 moves through the inner wall of the treatment box 100. The bottom end of the connecting tube 23 moves through the connecting shaft 63 and the positioning rod 22 in sequence and extends into the inner wall of the aeration tube 200. When the aeration tube 200 moves downward, the positioning rod 22 passes through the spiral path groove 2. When the positioning sleeve 42 and positioning tube 400 rotate in the opposite direction, the corner seat 721 on the inner wall of the positioning tube 400 drives the ratchet 72 to rotate synchronously. At this time, the ratchet 72 slides on the back of the teeth of the one-way ratchet 71, the torsion spring 722 is compressed, and the one-way ratchet 71 does not rotate. This design realizes the linkage between the lifting and lowering movement of the aeration pipe 200 and the switching action of the agent addition, so that the aeration process and the agent addition process are coordinated and linked, further improving the automation level and processing efficiency of the device operation. Multiple sets of inlet pipes 51 are connected to different types of agent sources, and each inlet pipe 51 is equipped with a metering pump 52 for precise control of the amount of agent extracted. The setting of the circulation positioning component 600 realizes the automated switching of agent addition.

[0031] In this embodiment, when the aeration pipe 200 moves downward, the positioning rod 22 drives the positioning sleeve 42 and the positioning pipe 400 to rotate in the opposite direction through the spiral path groove 221. The corner seat 721 on the inner wall of the positioning pipe 400 drives the ratchet 72 to rotate synchronously. At this time, the ratchet 72 slides on the back of the teeth of the one-way ratchet 71, the torsion spring 722 is compressed, and the one-way ratchet 71 does not rotate. Therefore, the connecting shaft 63 and the circulating positioning component 600 remain stationary and no agent switching occurs.

The setting of the circulating positioning component 600 realizes the automated switching of agent addition.

[0032] Working Principle: When this municipal engineering sludge resource utilization treatment device is in operation, the municipal engineering sludge to be treated is first introduced into the treatment tank 100 through the inlet pipe 12. Subsequently, an external air source or aeration equipment supplies air or oxygen to the aeration pipe 200 through the connecting pipe 23. The gas is released into the sludge mixture through the aeration holes on the aeration pipe 200. At this time, the rodless cylinder 300 is activated, and its movable end drives the first support 21 to move up and down reciprocally, thereby driving the aeration pipe 200 to move vertically up and down in the inner cavity of the treatment tank 100. The gas released from the aeration holes in the aeration pipe 200 can generate an agitation effect in the treatment tank 100, diffuse from the inside to the outside, and form turbulence with the sludge accumulated at the bottom of the treatment tank 100, so that the aeration pipe 200 can form a larger aeration area in the treatment tank 100.

[0033] When the aeration pipe 200 moves upward, its top positioning rod 22 slides inside the positioning sleeve 42 at the bottom of the positioning pipe 400. Because a spiral path groove 221 is provided between the positioning rod 22 and the positioning sleeve 42, the positioning rod 22 rotates forward while sliding upward. This rotation is transmitted to the positioning sleeve 42 through the positioning rod 22, thereby causing the positioning pipe 400 to rotate. The ratchet 72 installed on the corner seat 721 at the top of the inner wall of the positioning pipe 400 is engaged with the one-way ratchet 71 under the action of the torsion spring 722. Therefore, the forward rotation of the positioning pipe 400 will cause the one-way ratchet 71 to rotate synchronously. The one-way ratchet 71 then drives the positioning disc 61 located at the top of the filling tank 500 to rotate through the connecting shaft 63. The pin 611 at the bottom edge of the positioning disc 61 moves in a circular motion with the positioning disc 61. When the pin 611 moves to a certain pin groove 621 on the top of the adjusting seat 62, it is embedded in it and drives the adjusting seat 62 to rotate a certain angle, so that the connecting hole 623 on the bottom annular plate 622 of the adjusting seat 62 is aligned with the port of the inlet pipe 51 corresponding to the pin groove 621. At this time, the metering pump 52 connected to the inlet pipe 51 is started, and the corresponding agent is quantitatively drawn into the dosing tank 500, and then evenly sprayed into the sludge mixture in the treatment tank 100 through the connecting nozzle 53, and fully mixed with the bubbles generated by aeration.

[0034] When the aeration pipe 200 moves downward under the drive of the rodless cylinder 300, the positioning rod 22 drives the positioning sleeve 42 and the positioning tube 400 to rotate in the opposite direction through the spiral path groove 221. At this time, the ratchet 72 on the inner wall of the positioning tube 400 slides on the back of the teeth of the one-way ratchet 71, the torsion spring 722 is compressed, and the one-way ratchet 71, the connecting shaft 63 and the circulating positioning assembly 600 all remain stationary, and the agent addition channel does not switch.

[0035] This cycle repeats continuously. Through the up-and-down movement and rotation of the aeration pipe 200, efficient disturbance of the settled sludge at the bottom of the treatment tank 100 is achieved, expanding the aeration range and uniformity. Furthermore, the coordinated action of the synchronous unidirectional component 700 and the circulating positioning component 600 precisely controls the switching of different inlet pipes 51 and the activation of the metering pump 52, enabling automated and precise switching of various reagent additions. The treated sludge mixture can be discharged through the outlet pipe 13 at the bottom of the treatment tank 100. The entire process requires no manual intervention in pipe switching, significantly improving the automation level and treatment effect of sludge treatment.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes and modifications can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
