Abstract
Description
Technical Field
[0001] This utility model relates to the field of circulating heating reactors, and in particular to a circulating heating reactor for producing fish peptide fertilizer from marine fish. Background Technology
[0002] Fishmeal is a high-protein substance made from one or more types of fish through cooking, pressing, separation, and crushing. It is widely used in the feeding of livestock, aquatic animals, and fur-bearing animals, especially young animals. During the production of fishmeal, the material needs to be concentrated in a circulating heated reactor.
[0003] Chinese patent document CN107138118A discloses a multifunctional steam-heated reactor. The purification device disclosed in this reactor realizes the recycling of condensate and saves water. However, the purification device is difficult to fully separate the steam and concentrated liquid phases during the material concentration process. As a result, some of the concentrated liquid phase carried by the steam directly enters the next-effect evaporator as a heating medium, while the concentrated liquid remains inside the evaporator. This concentrated liquid contains a large amount of protein, which forms a viscous boundary layer that adheres to the inner wall of the evaporator and forms scale. This reduces the effect of subsequent evaporators in heating and vaporizing the material, thereby reducing the concentration effect of the material in the later stages. Utility Model Content

The spring guide rod passes through the limiting slide plate and the plug rod with a clearance fit. The limiting slide plate is welded to one end of the plug rod, and the other end of the plug rod is inserted into the edge of the mounting ring. The limiting slide plate slides within the sliding groove.
[0010] As a further embodiment of this utility model, the reactor includes a feed inlet, an insulation layer, a steam inlet, a condensate drain pipe, a concentrate drain pipe, and a steam guide pipe. The feed inlet is located at the top center of the reactor, and the insulation layer is wrapped around the outer periphery of the reactor.

[0015] 1. In this utility model, a drive mechanism and a baffle are installed inside the separation chamber. Steam is injected into the fan blades through the compression inlet. The fan blades drive the rotating shaft and the upper rotating rod to rotate. During the rotation of the rotating rod, the baffle rotates. When the steam mixed with the concentrated liquid collides with the baffle, the concentrated liquid forms droplets and falls downward. The upward-flowing steam needs to come into contact with the baffle again. Finally, the steam is intercepted by the metal wire mesh. The concentrated liquid forms large droplets on the metal wire mesh and falls downward, so that the steam and concentrated liquid are fully separated. This prevents the steam from entering the next effect evaporator and forming scale, which reduces the heating and vaporization effect of the subsequent evaporator on the material, thereby reducing the concentration effect of the material in the later stage.

In this utility model, by setting a plug-in rod at the upper end of the deflector, when the metal wire mesh is damaged after long-term use, the plug-in rod is separated from the inside of the mounting ring edge by sliding the limiting slide outward. The mounting ring and the metal wire mesh can be quickly removed from the deflector and replaced. After the new metal wire mesh is installed, the plug-in rod is elastically guided by the spring guide rod, so that the plug-in rod is stably inserted into the inside of the mounting ring edge without applying external force, and the mounting ring is firmly installed inside the deflector.

Detailed Implementation
[0024] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.
[0025] Please see Figure 1-5 In this embodiment of the utility model:
[0026] A circulating heating reactor for producing fish peptide fertilizer from marine fish includes a reactor 1, which is installed on the left end of a support frame 3, and a separation chamber 2 is installed on the right end of the support frame 3. The separation chamber 2 also includes a concentrate drain pipe 21, a drive mechanism 22, a rotating rod 23, a compression inlet 24, and a discharge outlet 25. The concentrate drain pipe 21 is welded to the bottom of the separation chamber 2, and the drive mechanism 22 is installed inside the lower end of the separation chamber 2. The rotating rod 23 is welded to the middle of the upper end of the drive mechanism 22. The compression inlet 24 is located on the left inner wall of the separation chamber 2 and is located to the left of the drive mechanism 22. The discharge outlet 25 is embedded in the top of the separation chamber 2. Steam is discharged into the separation chamber 2 through a steam guide pipe 16 at the right end of the reactor 1, and the steam is compressed and sprayed onto the surface of the fan blades 223 inside the cylindrical shell 222 through the compression inlet 24.
[0027] The compression inlet 24 has a frustum-shaped structure with a wide inlet and a narrow outlet. When steam enters the internal opening of the compression inlet 24, it is compressed by the internal diameter of the compression inlet 24, which increases the impact force of the steam sprayed onto the drive mechanism 22.
[0028] A baffle 231 is installed on the outer side of the upper end of the rotating rod 23 via a shaft connection. A pull rod 2311 is installed on the middle of the inner side of the baffle 231 via a shaft connection. There are two pull rods 2311, and another pull rod 2311 is installed on the outer surface of the rotating rod 23 via a shaft connection. A tension spring 2312 is provided between the two pull rods 2311. The driving mechanism 22 drives the rotating rod 23 to rotate.
[0029] The guide plates 225 are arranged in a ring on the inner wall of the cylindrical shell 222. The sixteen cylindrical shells 222 are arranged in a concave flow state between adjacent ones. When steam flows through the space between two guide plates 225 to the fan blade 223, it is pressurized and blows the fan blade 223, which is installed at an inclined angle on the outer surface of the rotating shaft 224, so that the fan blade 223 drives the rotating shaft 224 and the rotating rod 23 to rotate.
[0030] Four baffles 231 are provided, and two baffles 231 are arranged in a group. The two baffles 231 in each group are symmetrically installed, and the baffles 231 in the two groups are staggered vertically. The baffles 231 are installed in an inclined state that descends from the inside to the outside. An elastic tension is applied between the baffles 231 and the rotating rod 23 by a tension spring 2312. During the rotation of the rotating rod 23, the baffles 231 can not only rotate, but also the upper end of the baffles 231 can elastically swing around the axis connected to the rotating rod 23, thereby improving the interception of steam by the baffles 231. When the steam mixed with the concentrated liquid collides with the baffles 231, the concentrated liquid forms droplets and falls down.
[0031] The separation chamber 2 is equipped with a baffle 232 at its upper end, which is located above the baffle 231. An installation ring 2321 is fitted inside the lower end of the baffle 232, and a metal wire mesh 2322 is laid flat inside the installation ring 2321. A sliding groove 2323 is embedded inside the baffle 232, and a spring guide rod 2324 is fixedly installed inside the sliding groove 2323. The spring guide rod 2324 passes through the limiting slide plate 2325 and the plug rod 2326 with a clearance fit. The limiting slide plate 2325 is welded to one end of the plug rod 2326, and the other end of the plug rod 2326 is inserted into the edge of the installation ring 2321. The limiting slide plate 2325 slides within the sliding groove 2323.
[0032] The baffle 232 has a hollow frustum-shaped structure that is narrow at the bottom and narrow at the top. It is in the opposite direction to the inclination angle of the baffle 231. The upward-flowing steam needs to come into contact with the baffle 232 again before it can continue to flow upward.
[0033] The metal wire mesh 2322 is made of stainless steel and has a mesh count of 200. When the steam flows upward through the middle of the baffle 232, it comes into contact with the metal wire mesh 2322. The steam is finally intercepted by the metal wire mesh 2322, and the concentrated liquid forms large droplets on the metal wire mesh 2322 and then falls downward.
[0034] The spring guide rod 2324 consists of a guide rod and a spring. The spring guide rod 2324 provides elastic guidance for the insertion rod 2326, so that the insertion rod 2326 can be stably inserted into the inside of the edge of the mounting ring 2321 without the application of external force.
[0035] The reactor 1 includes a feed inlet 11, an insulation layer 12, a steam inlet 13, a condensate drain pipe 14, a concentrate drain pipe 15, and a steam guide pipe 16. The feed inlet 11 is located at the top center of the reactor 1, and the insulation layer 12 is wrapped around the outer periphery of the reactor 1. The steam inlet 13 penetrates through the insulation layer 12 and the interior of the reactor 1. The lower end of the reactor 1 is provided with a condensate drain pipe 14 that is connected through it. The bottom of the reactor 1 is welded with a concentrate drain pipe 15 that is connected through it. The right end of the reactor 1 discharges steam into the separation chamber 2 through the steam guide pipe 16.
[0036] The reactor 1 is equipped with a flow divider plate 131, which is connected to the upper end of the heat exchange tube 132. The steam inlet 13 discharges steam into the reactor 1 and the outside of the heat exchange tube 132. The steam inside the reactor 1 is kept warm by the insulation layer 12.
[0037] The reactor 1 above the flow divider 131 is also equipped with a film-forming device. The feed liquid is evenly distributed into the interior of multiple heat exchange tubes 132 at the lower end of the flow divider 131 by the liquid distributor on the film-forming device to form an initial liquid film.
[0038] The top of the outlet 25 is also connected to a steam outlet pipe 4, and a steam valve 5 is provided at the upper end of the steam outlet pipe 4.
[0039] The steam valve 5 is a control valve that is linked with the PLC to precisely control the pressure and flow rate of the steam being transported upward inside the separation chamber 2. When the control valve is connected to an external condenser, the steam can be condensed by the condenser (single-effect operation) or connected to the next-effect evaporator as a heating medium, thereby achieving multi-effect operation.
[0040] refer to Figures 1-5 In use, the material is discharged into the reactor 1 through the feed inlet 11. The liquid distributor on the film-forming device inside the reactor 1 evenly distributes the feed liquid into the multiple heat exchange tubes 132 at the lower end of the flow divider 131 to form an initial liquid film. Under the action of gravity, vacuum induction and airflow, the film flows from top to bottom in the heat exchange tubes 132. At the same time, the steam inlet 13 discharges external steam into the reactor 1 and the outside of the heat exchange tubes 132. At this time, the steam begins to heat and evaporate the liquid inside the heat exchange tubes 132. The liquid is heated and vaporized to form a concentrated liquid. Part of the concentrated liquid is discharged directly from the concentrated liquid discharge pipe 15, and part of the steam and liquid phase are discharged into the separation chamber 2 along the steam guide pipe 16.
[0041] Steam is injected into the fan blade 223 through the compression inlet 24. The fan blade 223 drives the rotating shaft 224 and the upper rotating rod 23 to rotate. During the rotation of the rotating rod 23, the baffle 231 rotates. When the steam mixed with the concentrated liquid collides with the baffle 231, the concentrated liquid forms droplets and falls down. The steam flowing upward needs to come into contact with the baffle 232 again. Finally, the steam is intercepted by the metal wire mesh 2322. The concentrated liquid forms large droplets on the metal wire mesh 2322 and falls down, so that the steam and the concentrated liquid are fully separated. The separated concentrated liquid is discharged downward from the concentrated liquid outlet pipe 21, while the steam is discharged upward along the steam outlet pipe 4.
[0042] When the wire mesh 2322 is damaged after long-term use, the insertion rod 2326 is separated from the inside edge of the mounting ring 2321 by sliding the limiting slide plate 2325 outward. The mounting ring 2321 and the wire mesh 2322 can be quickly removed from the baffle 232 and replaced. After the new wire mesh 2322 is installed, the spring guide rod 2324 provides elastic guidance for the insertion rod 2326, so that the insertion rod 2326 is stably inserted into the inside edge of the mounting ring 2321 without the application of external force, and the mounting ring 2321 is firmly installed inside the baffle 2322.

The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

The power supply is also common knowledge in the field.
