Description

Technical Field

[0001] This utility model belongs to the technical field of special equipment for sewage collection and treatment, and specifically relates to a sewage collection and treatment device. Background Technology

[0002] Before operation, a certain product requires the addition of a certain amount of fuel to the cargo hold to ensure the normal operation of the engine. Since the product's journey is relatively short, the fuel does not need to completely fill the cargo hold. Because fuel and water have different densities, and the fuel is denser than water, water is typically added to pressurize the fuel and supply it to the engine. During operation, fuel is continuously supplied to the engine, and water continuously enters the cargo hold to pressurize the fuel. After the voyage, the remaining small amount of fuel and water in the cargo hold needs to be collected and treated (hereinafter referred to as wastewater) to clean the cargo hold. The current method for treating the wastewater in the cargo hold is as follows: The cargo hold is placed on a high shelf, with a half-section oil drum below to collect the wastewater. The oil drum contains activated carbon, which can adsorb pigments, heavy metal ions, and other organic pollutants in the water, thus purifying the water. Below the oil drum is a support frame, and at the very bottom are casters (e.g.,...). Figure 1 As shown, when it is necessary to collect and treat sewage, this device needs to be pushed under the compartment, the compartment outlet is opened, and the sewage is allowed to flow into the barrel containing activated carbon. The activated carbon will adsorb and purify the sewage. After the sewage is adsorbed and purified, the purified water needs to be pumped out. Finally, the compartment is rinsed with alcohol to complete the sewage collection, treatment and cleaning tasks.

[0003] While current wastewater treatment equipment can treat wastewater, it still has the following technical drawbacks:

[0004] On the one hand, during the process of using a water pump to extract the purified water, the water pump will also extract some of the activated carbon, causing the water pump to become clogged.

[0005] On the other hand, the sewage treatment equipment currently in use makes it difficult to observe the sewage level in the tank. There is a risk of sewage overflow or being pumped out of the purified water because the position of the sewage at the bottom cannot be observed.

[0006] Another issue is that there is a certain distance between the discharge outlet of the compartment and the sewage treatment plant. When the sewage is released and encounters wind, the sewage will be blown out of the sewage treatment plant, causing pollution of the operating space. Subsequent cleaning requires manpower and time, which reduces work efficiency. Utility Model Content

[0007] In view of the many defects and deficiencies in the above-mentioned background technology, this utility model has made improvements and innovations, aiming to provide a sewage collection and treatment device. By setting a bracket to fix the filter element in the middle of the tank, and then setting a water outlet valve in the tank, sewage flows in from the middle of the filter element, is purified and flows out from the side or bottom of the filter element, and is then released by the water outlet valve, which effectively avoids the activated carbon clogging that occurs when using a water pumping device.

[0028] Preferably, the height of the filter element (13) is less than the height of the barrel body (12).

[0029] The working principle is as follows: Before using the wastewater collection and treatment device with the above-described design, the operator assembles the device:

[0030] During assembly, the operator first moves the tank body (12) onto the mobile lifting mechanism (2), adjusts the position so that the sewage collection tank (1) is located in the middle of the mobile lifting mechanism (2), inserts the sponge (133) between the outer filter screen (131) and the inner filter screen (132), pours the activated carbon granules (134) into the middle of the inner filter screen (132), and puts the filter element (13) into the tank body (12) by lifting the filter element handle (1312), and limits the filter element (13) by the inner bracket (121). At this time, the filter element (13) does not contact the inner side wall and bottom surface of the tank body (12). Then, the tank cover (11) and the tank body (12) are connected into a whole by the connector (114), thus completing the assembly of this utility model.

[0031] In use, the operator pushes the utility model from the storage location to the operating site by pushing the handle (221), opens the dust cover (1111), and raises the lifting frame (232) by operating the manual lifting system (231), which in turn raises the fixed plate (21) and the sewage collection bucket (1) connected to the fixed plate (21). When it is raised to below the compartment discharge port, the operator adjusts the position using the universal wheels so that the collection funnel (111) is directly below the compartment discharge port, opens the discharge port, and allows sewage to flow from the collection funnel (111). The wastewater flows into the wastewater collection tank (1) from 111), first being adsorbed by activated carbon particles (134), and then passing through the inner filter screen (132), sponge (133) and outer filter screen (131) in sequence to complete filtration. By observing the water level observation tube (123), when the wastewater collection tank (1) is full, the device is lowered and left to stand for a period of time to allow the activated carbon to fully adsorb. Then, according to the condition of the three layers of wastewater (high, medium and low), the outlet valve assembly (122) is opened to discharge the wastewater from high to low into the evaporation tank and the sludge tank respectively for further treatment.

[0032] During the filtration process, because the mass of a certain product fuel is greater than that of water, the filtered water is located in the upper layer and is discharged through the first outlet valve (1221). Some sewage is not fully filtered and is located in the middle layer and is discharged through the second outlet valve (1222). The bottom layer is a mixture of activated carbon powder and sewage that is rubbed off by sewage washing activated carbon particles (134) and is discharged through the third outlet valve (1223).

[0033] After the filtration is completed, the operator disassembles the connector (114) to separate the lid (11) from the body (12). The lid (11) is removed by holding and pulling the lid handle (113). Then the filter element (13) is completely removed by pulling the filter element handle (1312). The filter element base plate (135) is removed to take out the sponge (133) and activated carbon particles (134). The lid (11), filter element (13) and body (12) are cleaned. The sponge (133) and activated carbon particles (134) are discarded in the designated location. After cleaning, the parts are assembled according to the above steps and then pushed to the storage location to wait for the next use.

[0034] In summary, the beneficial effects of this utility model compared with the prior art are as follows:

[0035] 1. This utility model achieves better filtration by setting up a filter element structure, placing activated carbon particles inside the filter element, and sequentially setting an inner filter screen, a sponge, and an outer filter screen. Furthermore, by setting a water outlet valve along the side wall of the barrel, it avoids the situation of clogging caused by the extraction of activated carbon when using a water pump.

[0036] 2. This utility model, by incorporating a water level observation pipe, facilitates operators' observation of the water level within the sewage collection tank, preventing excessive sewage overflow and contamination of the work area during tank drainage. Furthermore, the transparent design allows operators to observe the stratification of the liquid within the sewage collection tank and utilize the outlet valve assembly to discharge different layers of liquid.

[0037] 3. This utility model, by setting up a mobile lifting mechanism, facilitates the transfer of sewage collection tanks by operators. Furthermore, the lifting frame assembly prevents sewage from tilting and spilling out due to wind during discharge, thus avoiding pollution.

[0038] 4. This utility model, by setting a funnel-shaped structure at the bottom of the tank, allows the sewage at the bottom layer to be discharged more effectively from the third outlet valve. Attached Figure Description

[0050] To make the technical means, inventive features, and achieved objectives and effects of this utility model readily understandable, the technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0051] Example 1

[0052] like Figures 1 to 8 The wastewater collection and treatment device shown includes: a wastewater collection tank 1 and a moving lifting mechanism 2; wherein, the wastewater collection tank 1 includes:

[0053] The lid 11 is connected to the body 12 via a connector 114 to cover the entire sewage collection bucket 1;

[0054] The barrel body 12 has several water outlet valve assemblies 122 and water level observation pipes 123 connected to the inside of the barrel on its outer side wall, and a barrel body support 124 is provided below and connected to the movable lifting mechanism 2.

[0055] The filter element 13 is mounted on the inner support 121 fixedly connected inside the barrel body 12;

[0056] The mobile lifting mechanism 2 includes:

[0057] The fixed plate 21 is mounted on the base plate 22 via the lifting frame assembly 23 at the bottom, and is used to place the sewage collection tank 1.

[0058] The lifting frame assembly 23 includes a manual lifting system 231 and a lifting frame 232. The manual lifting system 231 controls the lifting frame 232 to lift and lower the fixed plate 21.

[0059] The movable component 222 is mounted on the bottom surface of the fixed plate 21 and includes a roller and a locking mechanism for locking the roller.

[0060] Furthermore, the bucket lid 11 includes: a collection funnel 111, a vent 112, and a lid handle 113; the collection funnel 111 is fixedly connected to the middle of the bucket lid 11 and penetrates the bucket lid 11, and a dust cover 1111 is hinged to either side of the collection funnel 111 for sealing the collection funnel 111; the vent 112 is a vertical tubular structure that penetrates the bucket lid 11 for balancing the internal and external pressure of the sewage collection bucket 1; the lid handle 113 is symmetrically arranged on both sides of the collection funnel 111 for lifting the bucket lid 11.

[0061] In this utility model, such as Figure 2 As shown, operators collect wastewater discharged from the compartment outlet into a wastewater collection tank 1 using a collection funnel 111. The funnel design prevents wastewater from splashing out and contaminating the work area. Cleaning requires additional manpower and time, impacting work efficiency. The collection funnel 111 is equipped with a dust cover 1111. Figure 5 As shown, the dust cover 1111 should be closed when not in use to prevent dust from entering the wastewater collection tank 1 and affecting subsequent filtration operations. The vent is designed to balance the pressure inside and outside the tank during wastewater collection, preventing the wastewater from overflowing from the collection funnel 1 due to the constant pressure inside the tank preventing it from entering the wastewater collection tank 1.

[0062] Furthermore, the barrel body 12 includes: an inner support 121, a water outlet valve assembly 122, a water level observation tube 123, and a barrel body support 124; the inner support 121 is fixedly connected to the inner wall of the barrel body 12, the water outlet valve assembly 122 penetrates the barrel body 12 and is sealed, including a first water outlet valve 1221, a second water outlet valve 1222, and a third water outlet valve 1223, which are respectively located in the middle, lower, and bottom of the barrel body 12; the water level observation tube 123 is made of transparent material, with both ends extending from the outer wall of the barrel body 12 to the interior and sealed to the barrel body 12, and the middle part is fixed to the side wall of the barrel body 12 by several fasteners 1231; there are several barrel body supports 124, with both ends connected to the barrel body 12 and the movable lifting mechanism 2 respectively;

[0063] Among them, the first water outlet valve 1221, the second water outlet valve 1222 and the third water outlet valve 1223 are all connected to the water outlet pipe.

[0064] In this invention, the water level observation tube 123 is made of transparent material and is installed along the top to the bottom of the tank 12. During the wastewater collection process, the operator can determine the current wastewater level in the wastewater collection tank 1 by observing the liquid level position of the water level observation tube 123. When the wastewater collection tank 1 is about to be full, the operator stops the discharge of wastewater. After the wastewater is full, it is left to stand for a period of time to allow the filtered liquid to separate into layers. The operator can then observe the separation through the water level observation tube 123 and open the corresponding outlet valve assembly 122 to discharge the liquid of that layer.

[0065] Furthermore, the filter element 13 has a cylindrical structure, including: an outer filter screen 131, an inner filter screen 132, a sponge 133, activated carbon particles 134, and a filter element base plate 135; the top of the outer filter screen 131 is provided with an annular structure 1311, the diameter of which is larger than the diameter of the outer filter screen 131, so that the filter element 13 is mounted on the inner support 121, and filter element handles 1312 are symmetrically arranged on the annular structure 1311 for removing the filter element 13; a cylindrical sponge 133 is placed between the inner filter screen 132 and the outer filter screen 131; the inner filter screen 132 is fixedly connected to the filter element base plate 135, and activated carbon particles 134 are placed in the middle; wherein the diameter of the activated carbon particles 134 is larger than the pore size of the inner filter screen 132; the filter element base plate 135 is also a filter screen, which is detachably connected to the outer filter screen 131.

[0066] Before using the wastewater collection and treatment device with the above-described design, the operator assembles the device:

[0067] During assembly, the operator first moves the tank body 12 onto the mobile lifting mechanism 2, adjusts its position so that the sewage collection tank 1 is in the middle of the mobile lifting mechanism 2, inserts the sponge 133 between the outer filter screen 131 and the inner filter screen 132, and pours the activated carbon granules 134 into the middle of the inner filter screen 132. Figure 8 As shown, to achieve better filtration, activated carbon granules 134 are piled up to fill the inner filter screen. The filter element 13 is placed into the barrel 12 by pulling up the filter element handle 1312. The inner support 121 is engaged with the annular structure 1311 to limit the filter element 13. At this time, the filter element 13 does not contact the inner wall and bottom surface of the barrel 12. Then, the barrel cover 11 and the barrel 12 are connected into a whole by the connector 114, thus completing the assembly of this utility model.

[0068] In use, the operator pushes the handle 221 from the storage location to move the moving component 222 to the operating area, then opens the dust cover 1111. Figure 4As shown, the manual lifting system 231 is operated to raise the lifting frame 232, which in turn raises the fixed plate 21 and the sewage collection tank 1 connected to the fixed plate 21. When it is raised to below the compartment discharge port, the operator adjusts the position of the device using the casters, so that the collection funnel 111 is directly below the compartment discharge port. The discharge port is then opened, allowing sewage to flow into the sewage collection tank 1 along the collection funnel 111. Figure 2 As shown. After entering, the wastewater first passes through activated carbon particles 134 for adsorption, and then passes through the inner filter screen 132, sponge 133 and outer filter screen 131 in sequence to complete filtration. By observing the water level observation pipe 123, when the wastewater collection tank 1 is full, the device is lowered and left to stand for a period of time to allow the activated carbon to fully adsorb. Then, according to the condition of the three layers of wastewater (high, medium and low), the outlet valve assembly 122 is opened to discharge the wastewater from high to low into the evaporation tank and the sludge tank for further treatment. The water filtered from the top layer is discharged into the evaporation tank, and the remaining layers are discharged into the sludge tank.

[0069] During the filtration process, such as Figure 2 As shown, because the mass of a certain product's fuel is greater than that of water, the filtered water is located in the upper layer and is discharged through the first outlet valve 1221. A small amount of sewage is not fully filtered and is located in the middle layer, which is discharged through the second outlet valve 1222. The bottom layer is a mixture of activated carbon powder and sewage that has been rubbed off by the sewage scouring the activated carbon particles 134, and is discharged through the third outlet valve 1223.

[0070] After the filtration is completed, the operator disassembles the connector 114 to separate the lid 11 from the body 12. The lid 11 is removed by holding and pulling the lid handle 113. Then, the filter element 13 is completely removed by pulling the filter element handle 1312. The filter element base plate 135 is removed to take out the sponge 133 and activated carbon granules 134. The lid 11, filter element 13 and body 12 are cleaned. The sponge 133 and activated carbon granules 134 are discarded in the designated location. After cleaning, the parts are reassembled according to the above steps and then pushed to the storage location to wait for the next use.

[0071] Example 2

[0072] This embodiment 2 is the same as embodiment 1, except that the mobile component is also equipped with a sand component, such as... Figure 7 As shown, the sand component includes sand tires, tracks, or anti-skid chains, etc., to prevent the rollers from slipping and causing the vehicle to become immobile.

[0073] Furthermore, the rollers are omnidirectional wheels and equipped with sand-driving components, enabling them to travel on sand.

[0074] In this invention, the rollers are designed as omnidirectional wheels to facilitate alignment of the compartment discharge outlet. In some cases, wastewater collection and filtration operations are carried out on sand, therefore the rollers are equipped with sand-resistant components to prevent operators from slipping and being unable to move forward during transport.

[0075] Furthermore, the lower part of the barrel body 12 has a funnel-shaped structure, and the third water outlet valve 1223 is installed in the middle of the funnel-shaped structure.

[0076] In this utility model, the bottom structure of the barrel body 12 is funnel-shaped, such as... Figure 2 As shown, this method improves the efficiency of draining the bottom layer of wastewater and prevents residual wastewater from forming.

[0077] Furthermore, the pore size of the outer filter 131 is larger than that of the inner filter 132.

[0078] Furthermore, the connector 114 is a bolt or a snap fastener.

[0079] Furthermore, the manual lifting system 231 includes a lead screw assembly and a throttle handle. Rotating the throttle handle activates the lead screw assembly, causing the lifting frame 232 to rise or fall.

[0080] In this utility model, the operator rotates the throttle, thereby linking the screw assembly to raise or lower the lifting frame 232, which in turn raises or lowers the fixing plate 21, and raises or lowers the sewage collection tank 1, so that the collection funnel 111 is located below the discharge port of the compartment, effectively preventing sewage from splashing out when encountering wind during the sewage receiving process.

[0081] Furthermore, the height of the filter element 13 is less than the height of the barrel body 12.

[0082] In this invention, the height of the filter element 13 is less than the height of the barrel 12, so that the sewage is filtered out from the side wall and bottom of the filter element 13 during the filtration process, thereby increasing the filtration area and improving the filtration efficiency.

[0083] Example 3

[0084] This embodiment 3 is the same as embodiment 1 and embodiment 2, except that a sealing ring is provided at the connection between the lid 11 and the body 12 to prevent sewage from overflowing from the sewage collection bucket 1 during transportation.

[0085] In summary, a more specific embodiment of this utility model is as follows:

[0086] like Figure 3 As shown, a sewage collection and treatment device includes a sewage collection tank 1 and a mobile lifting mechanism 2.

[0087] Before use, the operator drills holes at the fixed positions on the lid 11 and the body 12. Then, the collecting funnel 111, vent 112, and lid handle 113 are welded to the lid 11. The water outlet valve assembly 122, water level observation tube 123, and fixing piece 1231 are connected to the body 12. The body 12 is then moved onto the mobile lifting mechanism 2, as follows: Figure 5 As shown, the position is adjusted so that the sewage collection tank 1 is located in the middle of the moving lifting mechanism 2 and welded. It is then placed between the outer filter screen 131 and the inner filter screen 132. Activated carbon granules 134 are poured into the middle of the inner filter screen 132. To achieve a better filtration effect, the activated carbon granules 134 are piled up to fill the inner filter screen. Figure 8 As shown, the filter element 13 is placed into the barrel 12 by pulling up the filter element handle 1312. The inner bracket 121 is engaged with the annular structure 1311 to limit the filter element 13. At this time, the filter element 13 does not contact the inner wall and bottom surface of the barrel 12. Then, the barrel cover 11 and the barrel 12 are connected into a whole by the connector 114, thus completing the assembly of this utility model.

[0088] In use, the operator pushes the handle 221 from the storage location to move the moving component 222 to the operating area, opens the dust cover 1111, and operates the manual lifting system 231 to raise the lifting frame 232. Figure 4 As shown, the fixed plate 21 and the sewage collection tank 1 connected to the fixed plate 21 are raised. When the tank is raised to below the discharge port of the compartment, the operator adjusts the position of the device using the universal wheels so that the collection funnel 111 is directly below the discharge port of the compartment. The discharge port is then opened, allowing sewage to flow into the sewage collection tank 1 along the collection funnel 111. After entering, the sewage is first adsorbed by activated carbon particles 134, and then sequentially filtered through the inner filter screen 132, sponge 133, and outer filter screen 131. By observing the water level observation pipe 123, when the sewage collection tank 1 is full, the device is lowered and left to stand for a period of time to allow the activated carbon to fully adsorb. Then, according to the three layers of sewage (high, medium, and low), the outlet valve assembly 122 is opened to discharge the sewage from high to low into the evaporation tank and the sludge tank for further treatment. The uppermost layer of filtered water is discharged into the evaporation tank, and the remaining layers are discharged into the sludge tank.

[0089] During the filtration process, such as Figure 2 As shown, because the mass of a certain product's fuel is greater than that of water, the filtered water is located in the upper layer and is discharged through the first outlet valve 1221. A small amount of sewage is not fully filtered and is located in the middle layer, which is discharged through the second outlet valve 1222. The bottom layer is a mixture of activated carbon powder and sewage that has been rubbed off by the sewage scouring the activated carbon particles 134, and is discharged through the third outlet valve 1223.

[0090] After the filtration is completed, the operator disassembles the connector 114 to separate the lid 11 from the body 12. The lid 11 is removed by holding and pulling the lid handle 113. Then, the filter element 13 is completely removed by pulling the filter element handle 1312. The filter element base plate 135 is removed to take out the sponge 133 and activated carbon granules 134. The lid 11, filter element 13 and body 12 are cleaned. The sponge 133 and activated carbon granules 134 are discarded in the designated location. After cleaning, the parts are reassembled according to the above steps and then pushed to the storage location to wait for the next use.

[0091] In this utility model, the connection is either a fixed connection or a detachable connection. The fixed connection is either a welded connection or a directly machined integral structure, while the detachable connection is either an internal or external threaded connection, a snap-fit ​​connection, or a plug-in structure connection.

[0092] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
