Description

Offshore machining center with assembly line type drying device

Technical Field

The present invention relates to a processing line and a processing method capable of directly processing marine products on the ocean surface.

Background

The background art is for the purpose of facilitating understanding of the technical contents of the present invention and is not prior art.

The earth's surface is divided into vast waters by continents to become oceans, the central part of the oceans is called oceans, the marginal parts are called seas, and the oceans are communicated with each other to form a uniform water body. The water of the ocean always flows according to a regular and definite form, and is not circulated, which is called ocean current. The prevailing wind is the main force that keeps the ocean current in motion; the density of seawater is different and is also one of the causes of ocean currents. Since the density of cold water is higher than that of warm water, the cold water sinks and the warm water rises. Islands and the coast of continents also have an effect on ocean currents, either by diverting the ocean currents or by dividing the ocean currents into sub-streams. In general, however, the majority of ocean currents circulate around the various basins. Due to the effect of earth rotation, the ocean current in the northern hemisphere flows in a clockwise direction, while the flow in the southern hemisphere flows in the opposite direction.

According to the reason of ocean current formation, the method can be divided into three categories:

1. wind and ocean currents: atmospheric motion and near-surface wind belts are the main power for the movement of marine bodies of water. The prevailing wind blows the sea surface to push the ocean water body to drift along with the wind, and the upper layer seawater drives the lower layer seawater to form a large-scale ocean current called wind ocean current.

2. Density flow: the temperature and salinity of seawater in each sea area are different, so that the density of the seawater is different, and the seawater flows, namely, the density flow. The distribution of density flow is generally apparent at straits between closed sea and open ocean.

3. Compensation flow: the ocean current formed by the difference of wind power and density reduces the seawater in the sea area from which the seawater flows out, and the seawater in the adjacent sea areas flows into the supplement because of the continuity of the seawater, and the supplemented ocean current is called compensation current. The formation of the compensating flow is closely related to the current of the wind, ocean and density. The separable vertical compensation flow is influenced by offshore wind, and due to blowing of the offshore wind, surface seawater comes off the shore, so that seawater in an adjacent sea area flows in to compensate for seawater loss, and lower seawater also rises to the sea surface to compensate for the flowing seawater, and an upwelling flow is formed. When the surface seawater meets the barrier of a coast or an island, the seawater is gathered and shunted in the horizontal direction, and a descending flow is generated in the vertical direction. The ascending flow can bring the nutritive salt substances at the bottom layer to the surface layer, so that plankton can grow in large quantity, and bait is provided for fishes.

In addition to the above factors, the formation of ocean currents is also influenced by the land shape and yaw forces, which force the ocean currents to change direction during movement. Ocean current formation is a result of a combination of factors that complicate, but regularly regulate, the distribution of ocean currents.

The motion forms of the ocean include wave motion, tides, and ocean currents. 1. Wave motion: the seawater is influenced by the action of sea wind, the change of air pressure and the like, so that the seawater is driven to leave the original balance position and moves upwards, downwards, forwards and backwards. This forms a wave at sea. Waves are a regular periodic rolling motion. 2. Tide: elastic-plastic deformation of the solid earth caused by daily and monthly tidal forces is called solid tide (ground tide); sea surface periodically goes up and down, rises and falls, and advances and retreats under the action of daily and monthly tidal force, which is called ocean tide (sea tide); the periodic variation (such as 8, 12, 24 hours) of each element of the atmosphere (such as an atmospheric pressure field, an atmospheric wind field, an earth magnetic field, etc.) caused by the action of the moisture-attracting force is called atmospheric tide (gas tide). Among them, atmospheric tides caused by the sun are called solar tides; the atmospheric tide caused by the moon is called the taiyin tide. The prime movers of the earth tide, the sea tide and the gas tide are caused by different gravitations of the earth in the day and the month, and the three have mutual influence. Elastic-plastic tidal deformation of the crust at the bottom of the ocean can cause corresponding sea tides, namely, the sea tides have the influence of the ground tide effect; the migration of sea water quality caused by sea tide changes the load born by the earth crust, so that the earth crust can be repeatedly bent. The tide is above the tide and acts on the sea surface to cause additional vibration, which further complicates the tidal change. The earth tide, sea tide and air tide are mutually influenced, so that the movement of the seawater is instantaneously changed in one day.

For a long time, the production of aquatic products is that a fishing boat carries out fishing operation on the ocean surface (offshore deep sea area), the fishing boat can send the fished aquatic products to a land processing plant to prepare marine products after going to the shore and returning to the port, five days and six days are needed for returning to the port, the aquatic products (such as small fish, shrimps and the like) are easy to decay and deteriorate, the additives are required to be used for corrosion prevention and preservation, excessive additives are harmful to human bodies, the country has clear requirements on the additive dosage, but the additives are frequently added in excess due to the long returning time of the ocean surface operating boat, so that the pollution to the marine products is caused, and the discharge pollution of the land processing plant in the process of preparing the marine products is also caused. How to keep the freshness of aquatic products without depending on additives is realized, and the aquatic products can be processed in time before going bad to become a problem to be solved.

It has been proposed to locate the marine product processing line on the ocean surface, but the ocean surface conditions are changing, the direction of the ocean currents, the height of the waves, the direction of the prevailing winds, the size of the vessel and the ton scale all affect the processing line, and no information is known about how to locate the marine product processing line in the sea area, in the ocean surface environment.

Detailed Description

The structures referred to in this application, or the terminology used, are further described below in the specification and drawings in a general sense and are not intended to be limiting, unless otherwise specified.

Aquatic products or materials

Aquatic products or materials, wherein the materials are edible organisms obtained by a fishing mode, and the aquatic products are used as raw materials of a processing center. Aquatic products include, but are not limited to, shrimps, small marine fish, mollusks, and the like. For example, shrimp includes, but is not limited to: red shrimps Dai, euphausia superba, penaeus monodon, prawns, metapenaeus ensis (metapenaeus), sagebrush (lutea), litopenaeus vannamei (white shrimp), acete chinensis, penaeus japonicus, penaeus monodon, penaeus gracilis (commonly known as litopenaeus), red shrimps in North China (sweet shrimp), prawns longeperis (arctic shrimp), antarctic deep-sea crayfish (antarctic shrimp), norwegian crayfish (williams), prawns exuberculus (peony), wide-angle red shrimps (wengowski penaeus), red shrimps in mule (Argentina shrimp), and prawns hamauns (skimmincus shrimp, live-skin shrimp). For example, small marine fish species include, but are not limited to: anchovy (clove fish), small silver fish, big silver fish, and multiple spring fish. For example, mollusks include, but are not limited to: baby squid, small octopus, etc.

Cargo ship

The fishing is to utilize various fishing gear, fishing boats and equipment to catch economic animals such as fish, shrimp, crab, etc. The general fishing boat is not used for processing aquatic products, and the processing boat is not used for fishing operation. Therefore, the aquatic products obtained by the fishing boat need to be transported to a processing center. We will collectively refer to as a delivery vessel, a fishing vessel or a carrier vessel that delivers goods to a machining center.

Detachable combination

A removable combination, as used herein, means that two elements are physically connected in a number of different positions or locations, e.g., when two elements are physically separated, when connected or combined together in a first instance where appropriate, and when two elements are separated in a second instance where appropriate, the separation being physically separate and not touching. Alternatively, the two components may initially be combined, and where appropriate, may be physically separated. In general, the combination of the two components or the separation of the two components can be easily performed, and the combination or the separation can be repeated for a plurality of cycles, and of course, the combination and the separation can be performed in a disposable manner. In addition, the two components can be detachably combined, and the three components or more than three components can be detachably combined. For example, there may be first, second and third parts, the first and second parts being removably combined, and the second and third parts also being removably combined.

Receiving, transferring and transferring

Receiving, transferring and transferring refer to that materials can be sequentially transferred from the previous process to the next process, for example, fresh aquatic products, cooked aquatic products and aquatic products in the drying process, dried marine products after drying can be transferred from the previous process to the next process, the aquatic products are discharged from the previous process and called discharging, and the aquatic products enter the next process and called receiving. The in-process of transmission probably passes through some physical structures that play the guide effect, for example through sealed pipeline intercommunication between the two processes, aquatic products pass through the pipeline and transmit one process next to from last process. The carrying can be realized by that the previous procedure and the next procedure do not have a direct connection relation, and the aquatic products can smoothly enter the inlet of the next procedure from the outlet of the previous procedure by means of the motion inertia and/or the motion track.

Negative pressure pump

Negative pressure pumps such as a fish suction pump, a shrimp suction pump and the like suck the aquatic product-water mixture by utilizing the vacuum negative pressure principle, the aquatic product is subjected to negative pressure, and the aquatic product is not damaged. The negative pressure pump has an impeller, the impeller rotates, the air sucked into the water inlet pipe is mixed with the water sucked from the water return valve in the impeller, and the air-water mixture is discharged into the air-water separation chamber through the pump body pumping chamber, the diffusion pipe and the water return window. The air in the mixture is lighter, escapes from the water and is exhausted to the atmosphere from the exhaust cup. The water separated from the air is sprayed to the impeller through the backwater valve body and the nozzle and is mixed with the sucked air again. The circulation is repeated, the air in the water inlet pipe is gradually exhausted, and finally the water is pumped normally. At this moment, the pressure difference between the inlet and the outlet of the water return valve body increases rapidly, the ball valve rises under the action of the pressure difference, the inlet of the water return valve body is closed, the backflow is cut off, and the pump runs under the working condition of a common centrifugal pump. When the machine is stopped, the pressure difference between the two ends of the water return valve body disappears rapidly, and the ball valve returns to the original position due to the self weight.

Control valve wrench

The speed of the negative pressure pump is controlled by a hydraulic oil circuit, a control valve is arranged on the hydraulic oil circuit, and the flow of the hydraulic oil circuit is controlled by the control valve. The control valve wrench is essentially a member for adjusting the flow rate of the control valve, and any member for controlling the flow rate, such as a straight wrench, a runner, a butterfly wrench, etc., should be considered as the control valve wrench.

Machining center

The processing center is provided with carriers capable of being moored on the sea surface and/or the ocean surface, the aquatic products captured by the capturing ship or the transport ship are transported to the processing center after being collected, the aquatic products captured by the capturing ship or the transport ship are fed to the processing center, and the aquatic products are cleaned, cooked, dried, sorted and cooled in the processing center; the drying adopts multi-section drying, and the drying and the sorting are performed alternately. Drying, removing shell of dried marine product (such as shelled shrimp and shelled shrimp), removing shell, and cooling. Or directly cooling without shelling (such as dried small fish, dried shrimps without shelling, etc.) after drying. After cooling, the marine products are classified according to size and specification and packaged after classification. Or classifying the shelled marine dried products according to size and specification, and packaging after classification. Or directly packaging after cooling. The processing center realizes the batch and rapid drying treatment of aquatic products at sea, and the treatment efficiency can reach ten thousand jin per hour.

In a first aspect of the invention, there is provided a processing center for marine product drying on a sea or ocean surface, the processing center comprising: the carrier is provided with a feeding device, a cleaning device, a cooking device, a drying device and a cooling device. The feeding device feeds the aquatic product raw materials to the processing center from the delivery ship, and the feeding device conveys the aquatic product raw materials to the cleaning device on the lower layer. The cleaning device cleans and conveys upwards to the cooking device at the same time, and the cleaning device cleans and filters water during the upward conveying process so as to control the water content of the aquatic product entering the cooking device; the cooking device finishes cooking the aquatic products, and the cooked aquatic products are input into the drying device.

Carrier

The carrier can be anchored on the ocean surface, the sea surface and the water surface by utilizing the buoyancy of water and is used for bearing the tool of the aquatic product processing line. Vectors include, but are not limited to: ships or vessels, offshore platforms, offshore man-made islands, etc. Offshore platforms include, but are not limited to: fixed offshore platforms and floating offshore platforms.

In some embodiments, the carrier is a ship or a ship. The carrier is a kiloton ship or more.

Feeding device

The carrier (such as a ship) of the processing center is anchored on the sea surface and/or the ocean surface, and the ship for delivery obtains the aquatic product raw materials and then transports the aquatic product raw materials to the processing center. Conventional transfer between two vessels is usually by the two vessels being in parallel, the two vessels being brought side by side and the cargo then being transferred or thrown from one vessel to the other. The carrier of the processing center is moored on the sea surface or the ocean surface, the transport ship and the fishing ship for sending the raw materials move, the moored carrier freely swings under the action of sea waves and ocean currents, and the transport ship and the fishing ship for sending the raw materials (hereinafter collectively referred to as a cargo ship) are controlled to run under the action of a power mechanism. Typically, the ton class of the delivery ship is much smaller than the ton class of the carrier of the machining center, for example, the delivery ship is a hundred-ton class ship, and the carrier of the machining center is kiloton class, five kiloton class and more. Conventionally, the side of a ship for delivering goods stops against the side of a machining center, and during the stopping process, due to the action of waves and ocean currents, frequent impact occurs between the two ships. When the cargo ship is far smaller than the carrier of the processing center, the two ships swing violently under the action of waves and ocean currents when being close to each other, and the height difference of the two ships is more than 2 meters generally. When such a boat is to be transported to a ship, it is common to erect a track between the two ships and then to slide the aquatic products contained in the baskets or trays from the boat to the ship, so-called sliping. However, due to the swing between the two ships, the cargo cannot be slid when there is wind and waves (when the height difference between the two ships exceeds 2 meters). Even when the wind is calm, the height difference between the two ships is generally more than 1 meter, loss of aquatic products scattered into the sea and the like can occur in the goods sliding process, the goods conveying amount at one time is basically more than hundreds of boxes (more than jacks), more personnel are needed for goods sliding, and the feeding speed is low.

If the cargo ship and the carrier of the processing center are all over kiloton, the impact force is very large when the two ships lean against each other on the ocean surface or the sea surface, and the two ships are likely to be damaged due to the inertia of the ship body. In this case, the material cannot be fed by a cargo sliding manner.

In order to ensure the safety of two ships and the safety of loading personnel during loading, the invention provides a loading device, which comprises a negative pressure pump 1, a material suction pipe 2 and a feeding channel 3, wherein the feeding channel 3 is connected to a discharge port 12 of the negative pressure pump, the discharge port end of the material suction pipe 2 is connected to an inlet 11 of the negative pressure pump, and a guide rope 21 is arranged at the material inlet end of the material suction pipe 2. The negative pressure pump 1 comprises a suction pump, a fish suction pump and the like for sucking aquatic products through negative pressure, and the structure of the negative pressure pump 1 is the prior art.

Material sucking pipe 2 of feeding device

When the two ships approach, the guide rope 21 is thrown to the delivery ship from the processing center, the delivery ship is connected to the guide rope 21, the guide rope 21 is pulled, and the material suction pipe 2 of the material suction pipe 2 is pulled to the delivery ship to be used as a channel for feeding materials from the delivery ship. After the material suction pipe 2 is pulled to the delivery ship, the delivery ship can leave a certain distance from the processing center to avoid collision.

In some embodiments: the guide rope 21 is tied at the feed inlet end of the material suction pipe 2. The material inlet end of the material suction pipe 2 is provided with a reinforcing sleeve 22. The reinforcing sleeve 22 is used for preventing the end part of the material suction pipe 2 from cracking, tearing and the like, so that the material suction pipe 2 cannot be sealed.

The material suction pipe 2 is used as a connecting channel between two ships, and a safe distance needs to be kept between the two ships, so that the length of the material suction pipe 2 is very long, and is usually dozens of meters or even hundreds of meters. Usually, the length of the suction pipe 2 is at least 50 meters, or 60-120 meters, in order to ensure a safe distance between the two vessels. The material suction pipe 2 is shorter than 50 meters, so that the two ships can collide end to end in the marine environment due to too close distance, and potential safety hazards are caused to the two ships. When the material suction pipe 2 is too long, the distance between the two ships is too long, the path is wasted, and the requirement on the suction force of the negative pressure pump 1 is high.

Therefore, in order to ensure smooth material suction, the self weight of the material suction pipe 2 cannot be too heavy, the pipe body of the material suction pipe 2 is made of light materials such as plastics, PP, resin and the like, and the material inlet end of the material suction pipe 2 is provided with the reinforcing sleeve 22 such as a metal ring sleeve, a hard plastic ring sleeve, a metal hoop and the like to protect the material inlet end of the material suction pipe 2. The reinforcing sleeve 22 is provided with a rope loop, and the guide rope 21 passes through or winds around the rope loop. The becket is to leading rope 21 play direction and damped effect, and the guide rope passes the becket, twines in the becket, perhaps winds around outside the becket, all is in order to lead the guide rope and prevent that guide rope 21 breaks away from suction pipe 2.

In some embodiments, the material suction pipe 2 is formed by splicing a plurality of sections of sub-pipes, and the sub-pipes are connected in a sealing manner. Preferably, the sub-pipes are connected through flanges and bolts; or the sub-pipes are connected with each other at the head, connecting pieces are arranged at the joints of the adjacent sub-pipes, and the connecting pieces are hoops, hoops or flexible wrapping sleeves wrapping the outer surfaces of the connecting pieces. Alternatively, in some embodiments, the suction pipe 2 is a continuous pipe.

Wear-proof assembly on material suction pipe 2

When the material suction pipe 2 is used, the carrier and the ship body swing along with waves, so that the material suction pipe 2 is severely rubbed with the edge of the carrier and the edge of the ship body, and in some embodiments, an anti-abrasion assembly is arranged around the outer part of the material suction pipe 2. Any structure that can alleviate wear of the suction pipe 2 by the ship can be used as the wear prevention assembly.

In some embodiments, the wear assembly includes a protective layer 23. The protective layer 23 not only protects the suction pipe 2 from direct abrasion, buffer impact and abrasion as much as possible, but also reduces the aging speed of the suction pipe 2 in the environments of sunshine, rain, sea wind corrosion and the like. For example, the protective layer 23 is a rope spirally wound outside the suction pipe 2; or a wear-resistant sleeve sleeved outside the material suction pipe 2. The protective layer 23 is typically a flexible material such as foam cushioning, foamed plastic, braided rope, or the like.

Alternatively, in some embodiments, the wear assembly comprises a wear frame 24 movably mounted outside the suction pipe 2, the wear frame comprising a body having a mating surface for mating with the suction pipe 2 and a wear surface, and a connecting portion. When in work, the wear-resistant surface is contacted and rubbed with the carrier and the ship body. A rigid body is preferred. The rigidity here is relative to the suction pipe 2, and a body which has a hardness greater than that of the suction pipe 2 and can support the self weight of the suction pipe 2 without deforming itself when the suction pipe 2 crosses the hull may be referred to as a rigid body. The body is a hollow cage formed by connecting a plurality of ribs, and the ribs are plastic ribs, resin ribs or metal ribs; alternatively, the body is a one-piece sheet of metal or plastic or resin. The connecting part is a bandage or a bandage rope fixed with the body.

In some embodiments, the material suction pipe 2 is externally provided with a protective layer 23, and the wear-resistant frame is arranged outside the protective layer 23. The protective layer 23 plays a role in wear resistance and buffering, and the wear-resistant frame plays a role in wear resistance and supporting the material suction pipe 2.

Valve of material suction pipe 2

In the process that the material suction pipe 2 is pulled to a transport ship from a processing center, the material suction pipe 2 can fall into the sea, and in order to prevent seawater from entering the empty material suction pipe 2, in some embodiments, the material inlet end of the material suction pipe 2 is provided with a valve 25. The function of the valve 25 is: 1. before the suction pipe 2 is pulled, the valve 25 is closed to prevent seawater from entering the suction pipe 2; 2. and after the feeding is finished, the valve 25 is closed, so that the aquatic products or water in the material suction pipe 2 are completely sucked away. Regardless of the form of the valve 25, it is sufficient if the opening and closing of the inlet is realized.

The valve 25 is a plug or stopper or cover. The plug and the choke plug can be flexible like silica gel and rubber, can also be foam, and can also be a flexible ring or a flexible sleeve sleeved on the rigid plug body, and the flexible sleeve seals the feeding port of the material suction pipe 2; or a sealing ring is sleeved on the sealing cover, and the sealing cover and the sealing ring seal the material suction pipe 2.

The flexible plug is provided with a tether which is tied at the feed inlet end of the material suction pipe 2. The protective layer 23 is formed by spirally winding a rope on the surface of the material suction pipe 2, wherein the rope is connected with a tether, or the tether is a part of the rope. Alternatively, the valve 25 is a mechanical valve 25, or the valve 25 is an electronic valve 25.
