Description

Technical Field

[0001] The invention discloses a treatment tank suitable for treating ship kitchen and waste water, which is used for treating ship kitchen and bilge waste water in inland and offshore navigation, and relates to the technical field of design and manufacture of ship waste disposal devices. Background Art

[0002] As the world is paying attention to environmental issues, domestic sewage on ships cannot be discharged at will. The main pollutants to the water and atmospheric environment generated by ships during navigation, berthing at ports, loading and unloading of cargoes, and operations on oil drilling platforms are oily sewage, domestic sewage, and ship garbage. According to international conventions, ships can only discharge domestic sewage that has been crushed and disinfected when using equipment approved by the competent authority 3 nautical miles away from the nearest land. It is not allowed to discharge domestic sewage that has not been crushed or disinfected. Moreover, the treated effluent should not produce visible floating solids in the surrounding water, nor should it discolor the surrounding water. Therefore, for the safety of the environment, the discharge management of waste generated on ships is very strict. This is because the pollutants contained in sewage and waste include organic matter and a large number of pathogenic microorganisms. Moreover, the organic matter in domestic sewage is extremely unstable and easily decomposes to produce odor, bacteria and pathogens. Therefore, it must be treated as required before discharge;

[0003] Current sewage treatment equipment mainly uses filter screens for filtration, but the existing filter screens are often clogged by large debris or debris contained in the sewage during use. It is also difficult to completely decompose the organic matter in the sewage by chemical liquid reactions, and there are still a lot of organic matter and pathogens left in the discharged wastewater.

[0004] The patent application document with publication number CN210215101U discloses a ship domestic sewage treatment equipment, which sets 4 oblique baffles in the anoxic tank, so that the original vertical straight-line flow direction of the water flow is changed to a zigzag flow direction, so that the water flow speed is slowed down, and flows to the left and downward. After several turns of the oblique baffles, the water flow speed is continuously slowed down, and the sewage is ensured to stay effectively in the anoxic tank by extending the path of the water flow in the anoxic tank and slowing down the water flow speed; the multiple oblique baffles set in the device extend the downstream speed of the sewage, and cannot fully extend the reaction time of the sewage and the chemical agent, and there is a situation of insufficient reaction, therefore, it is possible to cause the sewage that is not treated sufficiently to be discharged into the ocean, causing ecological pollution to the ocean, in addition, since no filtering and anti-blocking device is set, long-term use will still cause blockage of large debris or debris, affecting the use and life of the equipment;

[0005] Another application document with patent application number CN201810952572.8 discloses a sewage treatment device for ships, including a box body, four corners of the bottom of the box body are fixedly connected with legs, a box cover is arranged on the top of the box body, a disassembly handle is fixedly connected to the top of the box cover, a connecting plate is fixedly connected to the inner wall of the box body, a filter screen is arranged in the groove at the top of the connecting plate, a drop opening is opened at the bottom of the connecting plate, and a fixed block is fixedly connected to the left and right sides of the filter screen, and a fixing bolt is arranged on the top of the fixed block. The application can make the sewage treatment equipment used on the ship easy to remove sediments through the mutual cooperation of the support plate, the movable rod, the scraper, the port, the baffle, the movable plate, the sealing ring, the limit plate, the nut, the threaded rod, the rotating rod and the limit groove, so that the staff can easily complete the sediment removal work. However, since this method does not pre-treat the waste, the larger waste in the waste will still block the filter screen, and the oil and water in the wastewater cannot be separated. The oil contained in the sewage discharged into the water will still pollute the water body.

[0006] According to the 2011 Technical Rules for the Statutory Inspection of Inland Vessels, domestic sewage of ships sailing in inland waters should not be discharged into the waters at will. Domestic sewage of ships sailing on the Beijing-Hangzhou Grand Canal should be stored on board and discharged to receiving equipment. It is strictly prohibited to discharge domestic sewage into the waters. In order to solve the above problems and meet the requirements of the regulations, the utility model has designed a treatment tank for the disposal of kitchen waste and bilge sewage suitable for use in inland rivers and offshore, or offshore platforms in accordance with these regulations.

[0025] In order to explain the present invention in detail, the following is a preferred embodiment of the present invention:

[0026] Embodiment 1, the structure of the utility model

[0027] The utility model comprises a tank body 2, a restaurant kitchen waste treatment mechanism, an oil-water separation chamber 19 and a waste discharge mechanism. The tank body 2 is provided with a bilge oil-water separation chamber 19 and a restaurant kitchen waste treatment mechanism, and a clean water pipe 4 is provided on the top surface of the tank body 2. The oil-water separation chamber 19 is used to remove the bilge water accumulated from the bilge of the ship, and can timely treat the oily sewage in the bilge.

[0028] The bottom of the tank body 2 is provided with a kitchen waste water discharge valve 24, a slag discharge port 23, a drain valve 21, a drain filter 22, a drain valve 18 and a bottom bunker oil filter 17, which are used to dispose and discharge the collected kitchen waste. The kitchen waste residue treatment mechanism includes a kitchen waste residue conveying mechanism and a kitchen waste residue treatment bin. The kitchen waste residue conveying mechanism includes a kitchen waste residue crusher 27, a waste residue suction pump 26, and a kitchen waste residue conveying pipe 28. These devices can conveniently crush the kitchen waste generated by the ship during operation according to the specified requirements and then convey it to a further treatment mechanism for treatment;

[0029] A kitchen waste residue treatment device is arranged on the upper part of the kitchen waste residue treatment bin. The kitchen waste residue treatment device is composed of a kitchen waste input port 32, a water-residue separation outer cylinder 5 and a power mechanism. Small drainage holes 6 are evenly distributed at the front end of the water-residue separation outer cylinder 5, and a rectangular residue discharge slot 7 is arranged at the rear end of the water-residue separation outer cylinder 5. Small holes are evenly distributed at the front end of the water-residue separation outer cylinder 5. When the spiral shaft rotates, the input kitchen waste will be carried and moved. Under the squeezing of the spiral, the liquid contained in the input kitchen waste will leak from the small holes and be collected in the kitchen waste water bin 25 at the lower end. When the spiral shaft continues to rotate, the residue in the kitchen waste will be transported to the residue discharge slot at the rear end of the water-residue separation outer cylinder 5, and then the residue will fall down and fall into the waste residue storage bin 231 at the lower end.

[0030] The lower end of the kitchen waste water bin 25 is provided with a kitchen waste water discharge valve 24 and a waste water filter 241. The bottom of the waste residue storage bin 231 is provided with a residue discharge port 23. The kitchen waste water bin 25 and the waste residue storage bin 231 are separated by a partition plate 232. An upward arrow-shaped cap is provided at the upper end of the partition plate 232 for guiding and separating waste water and waste residue.

[0031] The power mechanism is composed of a motor 9, a reduction gear set and a gear shield 11. The reduction gear set includes a driving gear 101 installed on the output shaft of the motor 9, an intermediate gear 102 and a driven gear 10 fixed to the tail end of the screw shaft 3. For the purpose of deceleration, the diameters of the three gears increase in sequence from the driving gear 101, and the driven gear 10 is the largest, so as to achieve the purpose of deceleration. The gear shield 11 is fixed to the partition plate 191 by bolts, and the partition plate 191 is set up and down in the processing tank;

The baffle 12 is fixed on the top surface of the oil-water separation tank 19, facing the outlet of the bilge sewage delivery pipe 30. The wave-breaking plate 20 is installed on the bottom surface of the oil-water separation tank 19. Water holes are evenly arranged on the plate surface of the wave-breaking plate 20. The wave-breaking plate 20 can prevent the oil-water in the oil-water separation tank 19 from swinging greatly due to the shaking during the ship's driving process. , resulting in an unstable state of the treatment tank; the oil separator 15 is installed behind the anti-wave plate 20, and the height of the oil separator 15 is higher than the height of the anti-wave plate 20. The installed oil separator 15 does not leave any pores, forming a separation of oil and water in the oil-water separation chamber 19. Since the specific gravity of oil is lighter than that of water, it floats on the water in the oil-water separation chamber 19. When the reserve reaches the height of the oil separator 15, the oil floating on the surface will pass over the oil separator 15 and enter the oil storage tank 192, waiting to be discharged for treatment;

[0034] Example 2, the use process of the utility model

[0035] 1. Treatment of kitchen waste:

[0036] When the waste treatment tank is needed to treat the kitchen waste, the kitchen waste is first sent to the kitchen waste crusher 27 for waste crushing, and then the waste suction pump 26 sends the crushed waste into the treatment tank through the kitchen waste conveying pipe 28, and the waste enters the water-slag separation outer cylinder 5 of the kitchen waste treatment mechanism through the kitchen waste input port 32. Since a rotating spiral roller 3 is provided in the water-slag separation outer cylinder 5, the spiral roller 3 rotates continuously under the drive of the reduction gear set, pushing the crushed kitchen waste entering the water-slag separation outer cylinder 5. Under the push and squeeze of the spiral, the entered kitchen waste moves from the front end to the rear end. In the process of moving, the liquid in the kitchen waste will leak out of the outer cylinder small hole 6 provided at the front end of the water-slag separation outer cylinder 5 under the squeeze, and fall into the outer cylinder small hole 6 provided at the lower end. The remaining waste residue will continue to move to the rear end under the push of the spiral roller 3, and then be discharged from the water-slag separation outer cylinder 5 through the residue discharge slot 7 set at the rear end, and fall into the waste residue storage bin 231 set at the lower end; the waste water containing grease falling into the kitchen waste water bin 25 set at the lower end passes through the kitchen waste water discharge valve 24, and then passes through the waste water filter 241, and the qualified waste water is discharged into the water body, and the oily waste water is discharged into the preset bucket, and then temporarily stored until it is sent to the special recycling agency at the dock for recycling and treatment when the ship arrives at the dock; the kitchen waste residue falling into the waste residue storage bin 231 at the lower end is collected into a garbage bag or a temporary storage container through the residue discharge port 23, and when the ship arrives at any port for berthing, the garbage is placed at the garbage recycling point specified at the dock;

[0037] 2. Treatment of bilge wastewater:

[0038] When it is necessary to treat the wastewater containing oil in the bilge of the ship, the bilge sewage pump 29 is set to pump the bilge sewage into the oil-water separation tank 19. Since the pumped sewage has pressure, the incoming sewage will collide with the baffle 12, and then fall into the front end of the oil-water separation tank 19, where it will be precipitated for a short time. The solid containing particles will fall to the bottom of the tank and wait for removal and treatment. When the amount falling into the oil-water separation tank 19 increases, on the one hand, when the ship is shaking during navigation, the sewage in the tank will be restricted by the wave-breaking board 20, which can In order to avoid large surges and instability of the tank body, on the other hand, when the liquid level is higher than the oil separator 15, since oil is lighter than water, it will float on the liquid surface of the sewage. Therefore, when it is higher than the oil baffle 15, the oil floating on the liquid surface will pass over the oil separator 15 and fall into the oil storage tank 192; when the liquid in the treatment tank needs to be discharged, the drain valve 21 is opened, and the discharged sewage containing particulate solids passes through the drainage filter 22 to remove the particles and oil in the sewage, and then the qualified water can be directly discharged into the water body;

[0039] It should be noted that the drainage filter 22 and the bottom oil filter 17 are mature technologies and are products that filter solids and oil pollution up to standard. In this regard, ordinary technicians in this technical field can easily obtain technical products, so they will not be described in detail here.

[0040] When the oil and water level display tube 16 shows that the oil and water stored in the oil storage tank need to be discharged, the drain valve 18 is opened, and the stored oily and water is passed through the bottom tank oil filter 17 to collect the oil pollution. The water that meets the standards is directly discharged into the water body, and the absorbed oil pollution is collected and stored, and delivered to a special treatment agency at the port for treatment;

[0041] Example 3: Description of related equipment and disposal of emissions

[0042] 1. Description of related equipment

[0043] The sewage bottom silo oil filter 17 is a mature technology, and the products on the market are also products that filter oil pollution and meet the standards. In this regard, ordinary technicians in this technical field can easily obtain the technology and products, so they will not go into details here; the grinder, solid pump, and water pump involved are all existing technologies, and ordinary technicians in this field can easily understand what type of equipment is needed based on the size and content of the processing volume; the partition involved is fixedly installed using welding technology, which is also existing technology, as well as the fixation of the motor and the setting of the wires. Ordinary technicians in this field will easily understand the installation method, so they will not go into details here.

[0044] When the equipment processes domestic wastewater and waste for circulating flushing, the chemical agents and sterilizing agents that need to be added are also widely used existing technologies, and ordinary technicians in this field can easily obtain relevant technical guidance.

[0045] The reduction gear set consists of three gears, one is the power gear output by the motor, and the other is the passive gear that drives the screw shaft to rotate. An intermediate gear is arranged between the power gear and the passive gear. The purpose is to slow down the rotation speed of the screw shaft and increase the torque. The reduction ratio of the reduction gear is a conventional technology. Ordinary technicians in this field can easily derive the reduction ratio of the gear according to the required rotation speed, which will not be elaborated here.

[0046] The pulverizer arranged at the front end is used for crushing and post-processing of food waste. Equipment of different specifications can be selected according to the amount of food waste to be crushed. Ordinary technicians in this field can easily obtain the equipment on the market, so the structure and model of the pulverizer are not described in detail.

[0047] 2. Disposal of emissions

[0048] Before the discharged dry food waste is discharged from the processor, a deodorant can be sprayed on the waste through the provided water spray pump cleaning pipeline, or an environmentally friendly biological agent to prevent the growth of harmful organisms can be sprayed, and then the waste is packaged and temporarily stored. After arriving at each port, the stored dry food waste can be conveniently placed in the specified garbage collection bin;

[0049] Before the discharged oily liquid from the kitchen is discharged from this treatment tank, the kitchen wastewater collected every day is first precipitated and pre-treated in this treatment tank to settle the particulate pollutants mixed in the separation process. A precipitant can also be added to the kitchen wastewater to separate the grease in the wastewater. Biological bacteria can also be added to the infiltrated wastewater to metabolize the organic matter in the water with the biological bacteria to convert the organic matter into carbon dioxide, which is then discharged or collected and stored separately. After arriving at the port, different wastes are handed over to professional treatment respectively;

[0050] After the treatment is completed, the bilge water that does not contain oil or contains a small amount of oil and needs to be discharged is first passed through a filter before being discharged into the water body. The filter can be physical filtration or centrifugal separation. After filtration, the water can basically meet the discharge requirements and can be discharged in the prescribed manner. There are many types of filters involved, which can be solved by technical personnel in this field, so the selection of filters will not be described in detail.

[0051] The oily water discharged from the bottom bilge water of the ship to this treatment tank is precipitated in the treatment tank. After exceeding the height of the oil separator, since the oil floats on the water surface, when exceeding the height of the oil separator, the oil floating on the surface will automatically flow into the oil-containing tank containing the bottom oil. When the inventory reaches the amount that must be disposed of, it is discharged through the discharge valve. After discharge, it needs to pass through a filter to adsorb the oil contained in the water before it can meet the discharge standards and be discharged. The filter described here is a prior art, and ordinary technicians in this field can easily obtain the technology and equipment of the relevant filter, so it will not be described in detail here.

[0052] 3. The utility model can be provided with support legs at the four corners of the lower end of the tank body, and can also be provided on a skid-mounted frame. Since the provision of support legs or skid-mounted frames are both mature existing technologies, ordinary technicians in this technical field can easily install the tank body, and the related pump parts, valve parts, filters and other components on the support frame or on the skid-mounted frame according to the actual needs of the user. Therefore, it will not be described in detail here.
