Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, and in particular to a wastewater conveying system. Background Technology

[0002] The laboratory wastewater from ternary precursors is generally treated by directly discharging it into a pit, which results in a large amount of wastewater remaining in the pit.

[0003] Insufficient slope or excessive lateral length in drainage pipes can lead to blockages. Furthermore, wastewater in sump pits is typically filtered using a filter press to create filter cake; however, the treatment process for this filter cake is relatively complex, increasing both the difficulty and cost of treatment. Utility Model Content

[0004] Therefore, it is necessary to provide a wastewater conveying system that reduces the amount of wastewater generated from ditch materials.

[0005] This application provides a wastewater conveying system including a tank with a cavity; a baffle vertically arranged in the cavity, dividing the cavity into a first cavity and a second cavity, the baffle having filter holes distributed thereon, the first cavity communicating with the second cavity through the filter holes, and the wall of the first cavity having a wastewater inlet, the second cavity communicating with a storage tank through a drain pump; and a switch structure at least partially disposed in the second cavity, configured to activate the drain pump when the liquid level in the second cavity rises to a liquid level threshold, thereby conveying the wastewater in the second cavity to the storage tank.

[0006] In one embodiment, the first cavity and the second cavity are arranged sequentially along a first direction, the bottom of the cavity is provided with a gas supply pipe extending along the first direction, the baffle is provided with a perforation for the gas supply pipe to pass through, and the side wall of the gas supply pipe is provided with an exhaust port for venting gas into the first cavity and the second cavity respectively.

[0007] In one embodiment, the wastewater conveying system further includes an intake pipe for compressed gas, at least a portion of which is located within the first cavity, and the outlet of the intake pipe is connected to the gas delivery pipe.

[0008] In one embodiment, the air intake pipe includes a vertically arranged vertical pipe section and a horizontally arranged horizontal pipe section. The lower end of the vertical pipe section is connected to one end of the air supply pipe, and the upper end of the vertical pipe section is connected to one end of the horizontal pipe section. The second end of the horizontal pipe section passes through the wall panel of the first cavity.

[0009] In one embodiment, the pipe segment located in the first cavity of the gas transmission pipeline is defined as the first pipe segment, and the pipe segment located in the second cavity is defined as the second pipe segment. The end of the second pipe segment is closed, and both the second pipe segment and the first pipe segment are distributed with multiple sets of exhaust groups arranged at intervals along the first direction. Each set of exhaust groups includes at least one exhaust port.

[0010] In one embodiment, each group of exhaust ducts includes at least two exhaust ports arranged circumferentially spaced along the gas delivery duct.

[0011] In one embodiment, the wastewater delivery system further includes an inlet pipe for supplying hot water, at least a portion of which is located within the first cavity.

[0012] In one embodiment, both the water inlet pipe and the air inlet pipe are equipped with switch valves for opening and closing the corresponding pipes. The wastewater conveying system also includes a controller, a reminder device, and an observation device for observing the wastewater accumulation in the tank. The observation device is installed on the tank, and the signal output terminal of the observation device is electrically connected to the signal input terminal of the controller. The reminder device is electrically connected to the signal output terminal of the controller and is configured to remind the user to open and close the switch valves.

[0013] In one embodiment, the second chamber is connected to the inlet of the drain pump via a hose.

[0014] In one embodiment, the drain pump is a diaphragm pump with an air inlet for compressed air. The switching structure includes a float level gauge and a solenoid valve. The solenoid valve is located outside the second chamber, and the float level gauge is located inside the second chamber. The float level gauge is connected to the diaphragm pump through the solenoid valve.

[0015] Compared with the prior art, in the wastewater conveying system provided by this application, wastewater flows into the first chamber through the wastewater inlet. The wastewater in the first chamber is filtered through the filter holes on the baffle, which can prevent foreign objects from entering the second chamber, thus avoiding damage to the drainage pump. When the wastewater in the second chamber reaches the threshold, i.e., when the liquid level is relatively high, the drainage pump is controlled to start, thereby conveying the wastewater in the second chamber to the storage tank for effective recycling of wastewater materials, reducing the generation of ditch materials, and thus reducing the difficulty of treatment.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0025] like Figure 1 and Figure 2As shown, this application discloses a wastewater conveying system. The wastewater conveying system includes a storage tank 1, a tank body 2, a baffle 3, and a switch structure 4. The tank body 2 has a cavity 20. The baffle 3 is vertically arranged within the cavity 20, dividing the cavity 20 into a first cavity 201 and a second cavity 202. Filter holes 31 are distributed on the baffle 3, and the first cavity 201 is connected to the second cavity 202 through the filter holes 31. A wastewater inlet 211 is provided on the wall of the first cavity 201, and the second cavity 202 is connected to the storage tank 1 via a drainage pump.

[0026] The aforementioned switch structure 4 is at least partially disposed within the second cavity 202 and is configured to activate the drain pump when the liquid level in the second cavity 202 rises to a liquid level threshold, thereby transporting the wastewater in the second cavity 202 to the storage tank 1.

[0027] Understandably, wastewater flows into the first chamber 201 through wastewater inlet 211. The wastewater in the first chamber 201 is filtered through the filter holes 31 on the baffle 3. At this time, the filter holes 31 can prevent foreign objects from entering the second chamber 202, so as to avoid foreign objects entering the drainage pump and damaging the drainage pump. When the wastewater in the second chamber 202 reaches the threshold, that is, when the liquid level is relatively high, the switch structure controls the drainage pump to start. Under the action of the drainage pump, the wastewater in the second chamber 202 is transported to the storage tank 1, thereby realizing the effective recycling of wastewater materials, reducing the generation of ditch materials, thereby reducing the difficulty of ditch material treatment and saving ditch material treatment costs.

[0028] Specifically, such as Figure 1 As shown, the first cavity 201 and the second cavity 202 are arranged sequentially along the first direction A. In this embodiment, the bottom of the cavity 20 is provided with a gas supply pipe 51 extending along the first direction A, the baffle 3 is provided with a through hole 32 for the gas supply pipe 51 to pass through, and the side wall of the gas supply pipe 51 is provided with an exhaust port 5131 for venting gas into the first cavity 201 and the second cavity 202 respectively.

[0029] Understandably, the gas discharged through the exhaust port 5131 can enter the first chamber 201 and the second chamber 202, thereby impacting the material accumulated at the bottom of the first chamber 201 and the second chamber 202, preventing compaction or agglomeration caused by static settling, and facilitating the transportation of wastewater to the storage tank 1. No additional stirring system is required, making the entire system simpler.

[0030] In this embodiment, such as Figure 2 As shown, the filter hole 31 is located above the perforation 32.

[0031] Furthermore, such as Figure 1As shown, the wastewater conveying system also includes an intake pipe 52 for compressed gas, at least a portion of which is located within the first chamber 201, and the outlet of the intake pipe 52 is connected to the gas delivery pipe 51. Thus, the compressed gas entering through the intake pipe 52 flows into the gas delivery pipe 51, and then is discharged into the first chamber 201 and the second chamber 202 through the exhaust port 5131 of the gas delivery pipe 51. This impacts the material accumulated at the bottom of the first chamber 201 and the second chamber 202, preventing compaction or agglomeration due to settling, and facilitating the conveying of wastewater to the storage tank 1.

[0032] like Figure 1 As shown, the aforementioned air intake pipe 52 includes a vertically arranged vertical pipe section 521 and a horizontally arranged horizontal pipe section 522. The lower end of the vertical pipe section 521 is connected to one end of the air supply pipe 51, and the upper end of the vertical pipe section 521 is connected to one end of the horizontal pipe section 522. The second end of the horizontal pipe section 522 passes through the wall plate of the first cavity 201. This facilitates the delivery of compressed gas from the outside to the air supply pipe 51.

[0033] Specifically, the pipe segment located in the first cavity 201 of the gas transmission pipeline 51 is defined as the first pipe segment 511, and the pipe segment located in the second cavity 202 is defined as the second pipe segment 512. The end of the second pipe segment 512 is closed and defined as the closed end 5121. Both the aforementioned second pipe segment 512 and the first pipe segment 511 are distributed with multiple sets of exhaust groups 513 arranged at intervals along the first direction A. Each exhaust group 513 includes at least one exhaust port 5131. In this embodiment, each exhaust group 513 includes at least two exhaust ports 5131 arranged at intervals along the circumference of the gas transmission pipeline 51. This allows for more reliable impact on the material accumulated at the bottom of the first cavity 201 and the second cavity 202, further preventing compaction or agglomeration caused by stagnation.

[0034] Furthermore, the aforementioned wastewater conveying system also includes an inlet pipe 6 for supplying hot water, with at least a portion of the inlet pipe 6 located within the first chamber 201. The presence of the inlet pipe 6 allows hot water to be supplied into the first chamber 201, which improves solubility and prevents material sedimentation. The aforementioned hot water refers to hot pure water.

[0035] In this embodiment, the aforementioned inlet pipe 6 includes a vertically arranged vertical section 61 and a horizontally arranged horizontal section 62. The vertical section 61 is located in the first cavity 201, and the horizontal section 62 passes through the wall panel of the first cavity 201. Specifically, the wall panel where the wastewater inlet 211 is located is defined as the first wall panel 21. The aforementioned horizontal pipe section 522 and horizontal section 62 both pass through the first wall panel 21, and the horizontal section 62 is located above the horizontal pipe section 522, and both the horizontal section 62 and the horizontal pipe section 522 are located above the wastewater inlet 211.

[0036] Both the water inlet pipe 6 and the air inlet pipe 52 are equipped with corresponding valves for opening and closing. The wastewater conveying system also includes a controller, an alert device, and an observation device for observing wastewater accumulation in the tank 2. The observation device is mounted on the tank 2, and its signal output terminal is electrically connected to the signal input terminal of the controller. The alert device is electrically connected to the signal output terminal of the controller and is configured to remind the user to open and close the valves. The alert device can be a display screen or a buzzer. An observation port can be provided on the tank 2, and the observation device is located at the observation port. When sediment is observed at the bottom of the tank 2, the valves on the water inlet pipe 6 and the air inlet pipe 52 can be manually opened to flush and dissolve the bottom of the tank 2, thereby preventing material from settling at the bottom of the cavity 20.

[0037] The aforementioned observation device only needs to be able to observe the wastewater accumulation in tank 2, such as a camera. The working principle of the aforementioned reminder device, observation device, controller, and their mutual cooperation is the same as that of existing technology, and will not be described again in this embodiment.

[0038] Specifically, such as Figure 1 As shown, the switch valve on the air inlet pipe 52 is defined as the first valve 71, which can be installed on the horizontal pipe section 522. The switch valve on the water inlet pipe 6 is defined as the second valve 72, which can be installed on the horizontal section 62. To facilitate control of the first valve 71 and the second valve 72, they are located outside the cavity 20. When the first valve 71 and the second valve 72 are opened, hot pure water and compressed air can be introduced. The hot pure water and compressed air can impact and dissolve the material at the bottom of the first cavity 201, preventing compaction or agglomeration caused by standing.

[0039] The second chamber 202 is connected to the inlet of the drain pump via a hose 22. The drain pump can be a conventional pump or a diaphragm pump 8. In this embodiment, the drain pump is preferably a diaphragm pump 8, and the design of the hose 22 improves the service life of the diaphragm pump 8. The switch structure 4 includes a float level gauge 41 and a solenoid valve 42. The solenoid valve 42 is located outside the second chamber 202, and the float level gauge 41 is located inside the second chamber 202. The float level gauge 41 is connected to the diaphragm pump 8 via the solenoid valve 42. In addition, the solenoid valve 42 is connected to the air inlet pipe 43 for compressed air, so that compressed air can enter the diaphragm pump 8 through the solenoid valve 42.

[0040] Understandably, the solenoid valve 42 is switched on and off by the level signal from the float level gauge 41, thus enabling the connection and disconnection of the air source (compressed air) for the diaphragm pump 8, and achieving automatic control of the diaphragm pump 8. After the diaphragm pump 8 starts, the waste material in the second chamber 202 can be transported to the storage tank 1, realizing the recycling of waste material (or wastewater), reducing the generation of wastewater in the sewer, and saving on treatment costs.

[0041] The aforementioned storage tank 1 is a non-conforming tank for storing non-conforming waste materials.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
