Description

Technical Field

[0001] This application relates to the field of container cleaning, and more particularly to a cleaning and sewage discharge device and a cleaning station. Background Technology

[0002] In the production process of a flavoring compounding center, mobile tanks, as key containers for holding flavoring ingredients, are directly related to product quality and safety due to their cleanliness. After each use, the mobile tanks must be thoroughly cleaned at a cleaning station to remove residues and dirt. However, existing cleaning stations suffer from inefficiency in the wastewater discharge process. Traditional wastewater discharge methods mainly rely on gravity flow technology, with wastewater slowly flowing from the mobile tank into underground pipes. Due to the complex internal structure of the mobile tanks, sticky dirt easily accumulates at the bottom of the tank and at pipe valves, leading to poor wastewater discharge, especially when encountering stubborn deposits, significantly extending the discharge time. This inefficient wastewater discharge not only slows down the entire cleaning process and reduces the processing capacity of the cleaning station, but also may cause secondary pollution risks due to wastewater retention. Utility Model Content

[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a cleaning and sewage discharge device and a cleaning station.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: This application provides: A cleaning and sewage discharge device, comprising: A liquid supply assembly having at least one liquid outlet end; A cleaning head is provided at the outlet end of the liquid supply assembly, and a tank is provided at the cleaning station of the cleaning head, the tank having a drain port. The first drain pipe is connected to the drain outlet of the tank. The second drain pipe is connected to the first drain pipe; A suction pump is connected to the port of the second discharge pipe opposite to the first discharge pipe; A sewage pipe is connected to the port of the suction pump that is away from the second discharge pipe.

[0005] Furthermore, the liquid supply assembly includes a liquid supply pipe, at least one drain pipe is connected to the liquid supply pipe, a first switch is provided along the path of the drain pipe, and a liquid supply pump is also installed on the liquid supply pipe, the liquid supply pump being located upstream of the drain pipe.

[0006] Furthermore, a quick connector is connected to the port of the first drain pipe facing the tank, the quick connector being used to connect the first drain pipe to the drain outlet of the tank.

[0007] Furthermore, a second switch is installed along the path of the first discharge pipe.

[0008] Furthermore, a pipe connection assembly for connection is provided between the suction pump and the second discharge pipe, and between the suction pump and the sewage pipe.

[0009] Furthermore, the pipeline connection assembly includes a first flange and a second flange, and a connecting clamp is provided between the first flange and the second flange for connecting the first flange and the second flange.

[0010] Furthermore, the connecting clamp includes a first clamp ring and a second clamp ring that are rotatably connected to each other, and the inner walls of the first clamp ring and the second clamp ring are provided with annular grooves to form a limiting cavity; The first hoop has an installation groove at its end and the second hoop has an avoidance groove at its end. A stud is provided in the installation groove, which is rotatably connected to the end of the first hoop and extends through the avoidance groove. A bolt is provided on the stud.

[0011] Furthermore, a sealing element is provided between the first flange and the second flange, the sealing element being located in the limiting cavity, the sealing element including a sealing gasket and a covering ring, the covering ring being disposed on at least one circumferential edge of the sealing gasket.

[0013] This application also provides a cleaning station, including the cleaning and sewage discharge device described in any one of the above-mentioned methods.

[0014] This application connects a suction pump to a second discharge pipe and a sewage pipe, using the suction action of the pump to accelerate the discharge of sewage from the tank's discharge port through the first and second discharge pipes to the sewage pipe. This effectively overcomes the problems of poor sewage discharge and low efficiency caused by traditional gravity-fed sewage flow, significantly improves the sewage discharge speed, and reduces the residence time of sewage in the tank and pipes, thereby reducing the risk of secondary pollution. At the same time, the negative pressure generated by the suction pump prevents sewage from accumulating in the pipes, further ensuring the continuity and efficiency of sewage discharge.

[0024] This application provides a cleaning and sewage discharge device, which includes a liquid supply component 100, a cleaning head 200, a first discharge pipe 300, a suction pump 500, and a sewage discharge pipe 600. The liquid supply component 100 has at least one liquid outlet end. The cleaning head 200 is disposed at the liquid outlet end of the liquid supply component 100. A tank 210 is disposed at the cleaning station of the cleaning head 200. The tank 210 has a sewage discharge port. The first discharge pipe 300 is connected to the sewage discharge port of the tank 210. A second discharge pipe 400 is connected to the first discharge pipe 300. The suction pump 500 is connected to the port of the second discharge pipe 400 away from the first discharge pipe 300. The sewage discharge pipe 600 is connected to the port of the suction pump 500 away from the second discharge pipe 400.

[0025] Please see Figure 1 As shown, the outlet of the tank 210 is connected to an outlet pipe, and a hand valve 211 is installed on the outlet pipe. The hand valve 211 controls the connection and disconnection of the outlet pipe. It can be understood that the outlet of the outlet pipe is a drain outlet, which is connected to the first drain pipe 300. In this embodiment, the cleaning fluid is clean water. Furthermore, in order to improve the cleaning effect, the cleaning fluid should be clean hot water, thereby accelerating the dissolution of dirt and improving the cleaning efficiency.

[0026] In this embodiment, during cleaning, the cleaning head 200 is first moved to its cleaning position. Then, hot water from the liquid supply assembly 100 is sprayed onto the tank 210 through the cleaning head 200 to dissolve the dirt inside the tank 210. The wastewater flows from the drain port, guided by the connection between the first drain pipe 300 and the second drain pipe 400, to the drain pipe 600, thus discharging the wastewater. Furthermore, to accelerate the discharge of wastewater, a suction pump 500 is installed at the connection between the second drain pipe 400 and the drain pipe 600. The suction pump 500 rapidly draws the wastewater in the second drain pipe 400 to the drain pipe 600, thereby improving the discharge efficiency. Under the suction action of the suction pump 500, the drain port of the tank 210, the first drain pipe 300, and the second drain pipe 400 are all under negative pressure, which prevents water from accumulating inside due to insufficient flow, further improving the discharge efficiency.

[0027] For example, the suction pump 500 is a pneumatic diaphragm pump.

[0028] In some embodiments, the liquid supply assembly 100 includes a liquid supply pipe 110, at least one drain pipe 120 is connected to the liquid supply pipe 110, a first switch 130 is provided on the path of the drain pipe 120, and a liquid supply pump 140 is also installed on the liquid supply pipe 110, the liquid supply pump 140 being located upstream of the drain pipe 120.

[0029] Please continue reading. Figure 1As shown, a hot water source is connected to the upstream via a supply pipe 110, and a supply pump 140 is installed along the path of the supply pipe 110. The supply pump 140 provides power for the delivery of hot water, that is, the hot water is delivered from the supply pipe 110 to the drain pipe 120, so that there is a certain water pressure in the pipeline, which provides power for the cleaning head 200 to spray and clean. In this embodiment, in order to prevent water from continuously flowing from the supply pipe 110 to the cleaning head 200 through the drain pipe 120, a first switch 130 is installed on the drain pipe 120. The water can be blocked from the drain pipe 120 as needed to prevent water from spraying out of the cleaning head 200 when cleaning is not required.

[0030] For example, the first switch 130 is a valve that can be automatically controlled, such as a pneumatic control valve or a solenoid valve.

[0031] For example, in order to improve the cleaning efficiency of the tank 210, multiple drain pipes 120 can be connected on the path of the supply pipe 110, and each drain pipe 120 is equipped with a corresponding cleaning head 200 at its end and a first switch 130 is installed on its path. In this embodiment, there are two drain pipes 120 and they are connected to the supply pipe 110.

[0032] In some embodiments, a quick connector 310 is connected to the port of the first drain pipe 300 facing the tank 210. The quick connector 310 is used to connect the first drain pipe 300 to the drain port of the tank 210.

[0033] like Figure 1 As shown, in order to facilitate the connection between the first drain pipe 300 and the drain port of the tank 210, a quick connector 310 is installed at the port of the first drain pipe 300. The quick connector 310 can be quickly connected or disconnected from the drain port, thereby enabling the quick cleaning of different tanks 210.

[0034] For example, quick connector 310 can be a plug-in check connector.

[0035] In some embodiments, a second switch 320 is provided along the path of the first drain pipe 300.

[0036] Understandably, since the cleaning head 200 has multiple cleaning capabilities for multiple tanks 210, in order to prevent external air from entering the second drain pipe 400 through one of the first drain pipes 300 and causing the internal air pressure to be insufficient for suction when only one tank 210 needs to be cleaned, it is necessary to close the unused first drain pipe 300. That is, a second switch 320 needs to be installed on the path of the first drain pipe 300 to switch it between connection and disconnection.

[0037] For example, the second switch 320 is a valve that can be automatically controlled, such as a pneumatic control valve or a solenoid valve.

[0038] In some embodiments, a pipe connection assembly 700 is provided between the suction pump 500 and the second discharge pipe 400, and between the suction pump 500 and the sewage pipe 600, for connection. The pipe connection assembly 700 includes a first flange 710 and a second flange 720, and a connecting clamp 730 is provided between the first flange 710 and the second flange 720 for connecting the first flange 710 and the second flange 720.

[0039] Please see Figure 2 and Figure 3 As shown, in order to connect the inlet end of the suction pump 500 to the second drain pipe 400 and the outlet end of the suction pump 500 to the sewage pipe 600, a pipe connection assembly 700 is provided between the suction pump 500 and the second drain pipe 400 and between the suction pump 500 and the sewage pipe 600 for connection.

[0040] Specifically, the first flange 710 is connected to the second drain pipe 400, and then the second flange 720 is connected to the sewage pipe 600. The first flange 710 and the second flange 720 are fixedly connected by a connecting clamp 730, thereby realizing the connection between the liquid inlet end of the suction pump 500 and the second drain pipe 400, and the liquid outlet end of the suction pump 500 and the sewage pipe 600.

[0041] In this embodiment, both the first flange 710 and the second flange 720 are composed of a pipe body and a disc body. The two disc bodies are connected by a connecting clamp 730 to achieve communication between the two pipe bodies.

[0042] In some embodiments, the connecting clamp 730 includes a first clamp ring 731 and a second clamp ring 732 that are rotatably connected to each other. The inner walls of the first clamp ring 731 and the second clamp ring 732 are provided with annular grooves to form a limiting cavity 7301. The end of the first clamp ring 731 is provided with a mounting groove 7311, and the end of the second clamp ring 732 is provided with a clearance groove 7321. A stud 733 that is rotatably connected to the end of the first clamp ring 731 and extends through the clearance groove 7321 is provided in the mounting groove 7311. A bolt 734 is provided on the stud 733.

[0043] Please see Figure 4 and Figure 5 as well as Figure 6As shown, in order to enable the first flange 710 to communicate with the second flange 720, the first hoop 731 and the second hoop 732 are combined such that a limiting cavity 7301 formed by annular grooves on the inner walls of the first hoop 731 and the second hoop 732 accommodates the disc body. At this time, the mounting groove 7311 and the clearance groove 7321 are located in the same position. After the disc body of the first flange 710 and the second flange 720 is accommodated in the limiting cavity 7301, the stud 733 can be rotated through the clearance groove 7321, and then the bolt 734 is installed on the stud 733 to tighten the first hoop 731 and the second hoop 732 to prevent them from separating.

[0044] In some embodiments, a sealing element 740 is provided between the first flange 710 and the second flange 720. The sealing element 740 is located in the limiting cavity 7301. The sealing element 740 includes a sealing gasket 741 and a covering ring 742. The covering ring 742 is disposed on at least one circumferential edge of the sealing gasket 741.

[0045] Please see Figure 5 , Figure 6 as well as Figure 7 As shown, in order to prevent sewage from leaking out from the gap between the first flange 710 and the second flange 720, when the first flange 710 and the second flange 720 are connected by a connecting clamp 730, a sealing element 740 is provided between the first flange 710 and the second flange 720 to seal the gap and prevent sewage from overflowing.

[0046] Furthermore, the sealing element 740 includes a sealing gasket 741 and a covering ring 742 disposed at the axial side edge of the sealing gasket 741. It should be noted that the inner diameter of the covering ring 742 should be equivalent to the outer diameter of the disc of the first flange 710 and the second flange 720, so as to be able to cover the disc inside. In practice, since the covering ring 742 has a certain elasticity, the disc of the first flange 710 and the second flange 720 is press-fitted with the covering ring 742, thereby further improving the sealing performance. In this embodiment, the sealing gasket 741 is provided with the covering ring 742 on the side circumference facing the second flange 720, so as to cover the disc of the second flange 720.

[0047] In another embodiment, a covering ring 742 is provided at the circumferential edge of both sides of the sealing gasket 741, so that the discs of the first flange 710 and the second flange 720 can be covered, thereby further improving the sealing performance.

[0048] In some embodiments, the first flange 710 has a first sealing groove 711 on the side facing the sealing gasket 741, and the side of the sealing gasket 741 is provided with a first annular protrusion 7401 extending into the first sealing groove 711. The second flange 720 has a second sealing groove 721 on the side facing the sealing gasket 741, and the side of the sealing gasket 741 away from the first annular protrusion 7401 is provided with a second annular protrusion 7402 extending into the second sealing groove 721.

[0049] To further improve the sealing performance between the first flange 710, the second flange 720 and the gasket 741, annular sealing grooves are provided on the end faces of the first flange 710 and the second flange 720, and corresponding annular protrusions are provided on both sides of the gasket 741. During installation, the annular protrusions extend into the annular sealing grooves to achieve a seal.

[0050] Please see Figure 7 As shown, specifically, a first sealing groove 711 is formed on the disc end face of the first flange 710, and a first annular protrusion 7401 is provided on the side of the sealing gasket 741 facing the first flange 710, and the first annular protrusion 7401 extends into the first sealing groove 711 to achieve a seal; similarly, a second sealing groove 721 is formed on the disc end face of the second flange 720, and a second annular protrusion 7402 is provided on the side of the sealing gasket 741 facing the second flange 720, and the second annular protrusion 7402 extends into the second sealing groove 721 to achieve a seal.

[0051] This embodiment also provides a cleaning station, which includes the cleaning and sewage discharge device and the conveyor described in any one of the above-mentioned methods. The conveyor is used to transport the tank 210 to the cleaning station of the cleaning head 200. The type of conveyor can be selected according to the actual working conditions and is not limited here.
