Description

Technical Field

[0001] This utility model relates to the field of solvent leaching equipment technology, and in particular to a solvent spraying and recovery device for a horizontal leaching machine. Background Technology

[0002] Horizontal leaching machines are widely used solid-liquid extraction devices in the production of materials such as oils and proteins. Their basic working process involves spraying solvent onto the material layer to dissolve the target components, thereby achieving separation and extraction.

[0003] The uniformity of solvent spraying directly determines the leaching efficiency and the quality of the final product. Currently, many horizontal leaching machines use fixed spray pipes or nozzle arrays to spray the material. This design is simple and easy to implement.

[0004] Because the material layer thickness and density are difficult to maintain perfectly uniform as it moves and accumulates within the leachator, fixed spraying methods often result in uneven solvent distribution. Some areas may develop "channels" due to excessive solvent, leading to solvent waste, while other areas may form "leaching dead zones" due to insufficient solvent spraying. These areas of inadequate leaching directly reduce the overall leaching rate. To achieve the desired extraction effect, it is often necessary to extend the leaching time or increase the solvent circulation volume, thereby increasing production energy consumption and costs.

[0005] Therefore, this utility model proposes a solvent spraying and recovery device for a horizontal leaching machine to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a solvent spraying and recovery device for a horizontal leaching machine, which aims to improve the problems of uneven solvent distribution, easy formation of leaching dead zones, and low leaching efficiency caused by the use of fixed spraying in the existing technology of solvent spraying and recovery devices for horizontal leaching machines.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a solvent spraying and recovery device for a horizontal leaching machine, comprising: a horizontal leaching machine shell, a rising film evaporator, a separator, a feed pipe, a discharge pipe, a reflux pipe; and a large-area spraying mechanism.

[0008] The large-area spraying mechanism includes a guide rail fixed to the top of the inner wall of the horizontal leachate housing, a spray pipe slidably connected to the guide rail via a slider, and a drive assembly for driving the spray pipe to move.

[0009] The drive assembly includes a motor fixedly mounted on the top of the horizontal leachate housing, a rotating plate connected to the output shaft of the motor, and a connecting plate; both ends of the connecting plate are rotatably connected to the rotating plate and the spray pipe, respectively; the spray pipe is connected to the return pipe through a connecting hose.

[0010] Preferably, the solvent spraying and recovery device for the horizontal leaching machine further includes an anti-scalding connector mechanism, which is connected to the rising film evaporator and is used for detachable connection with the air inlet pipe; the anti-scalding connector mechanism includes a threaded connector, a sealing head housed in the internal cavity of the threaded connector, and a spring located behind the sealing head; the front end of the air inlet pipe is formed with an unlocking head for pressing against the sealing head.

[0011] Preferably, a throttle handle for turning is fixed on the outer wall of the air intake pipe.

[0012] Preferably, a sealing strip is installed on the front end of the sealing head facing the unlocking head, and an annular valve seat that mates with the sealing strip is formed inside the threaded joint.

[0013] Preferably, the spray pipe is provided with multiple nozzles at intervals.

[0014] Preferably, a protective shell is fixed to the outside of the motor.

[0015] Preferably, one end of the connecting plate is rotatably connected to the edge of the rotating plate, and the other end is rotatably connected to the side wall of the spray pipe.

[0016] Preferably, the slider is fixed to the top outer wall of the spray pipe, and the outer contour of the slider slides in conjunction with the inner wall groove of the guide rail.

[0017] Preferably, the lower part of the rising film evaporator is also connected to a condensate pipe for draining condensate.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, a large-area spraying mechanism consisting of a motor, a rotating plate, a connecting plate, and a guide rail spraying pipe is first set up. This converts the rotational motion of the motor into the reciprocating linear motion of the spraying pipe, solving the problems of dead corners and uneven spraying in the existing spraying devices. This achieves the technical effect of large-area and uniform spraying of materials, and significantly improves the solvent leaching efficiency and utilization rate.

[0020] 2. In this utility model, by setting an anti-scalding joint mechanism consisting of a spring, a sealing head, an unlocking head, and a threaded joint in the steam pipeline, the automatic sealing is achieved when the pipeline is disconnected by using the spring reset.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-5The present invention provides an embodiment of a solvent spraying and recovery device for a horizontal leaching machine, which aims to solve the problems of limited spraying coverage and easy formation of dead zones in the existing solvent spraying device, as well as the safety hazard of high-temperature steam leakage that could burn operators when the steam heating pipeline is disassembled.

[0030] The solvent spraying and recovery device for the horizontal leaching unit includes a horizontal leaching unit shell 1, a rising film evaporator 2, a separator 3, and a large-area spraying mechanism 7. The horizontal leaching unit shell 1 serves as the main installation body and material handling platform of the entire device. The rising film evaporator 2 is connected to the horizontal leaching unit shell 1 through a feed pipe 4 and is used to heat and evaporate the material. The separator 3 is connected to the top of the rising film evaporator 2 and is used to separate the gas-liquid mixture. The separator 3 is connected to a discharge pipe 5 for discharging the product and a return pipe 6 for recovering the solvent.

[0031] The large-area spraying mechanism 7 is installed above and inside the horizontal leachate housing 1. The large-area spraying mechanism 7 includes a guide rail 703 as a motion track, a spray pipe 705 that reciprocates along the guide rail 703, and a drive assembly that drives the spray pipe 705 to move. The guide rail 703 is fixed to the top of the inner wall of the horizontal leachate housing 1. The spray pipe 705 is slidably connected to the guide rail 703 through a slider 704. The spray pipe 705 is connected to the return pipe 6 of the recovered solvent through a connecting hose 707, and is used to receive and spray the recovered solvent.

[0032] The drive assembly is the power source and transmission mechanism for realizing the reciprocating motion of the spray pipe 705. The drive assembly includes a motor 702, a rotating plate 708, and a connecting plate 709. The motor 702 is fixedly installed on the top of the horizontal leaching tank shell 1 and serves as the power source for the entire drive assembly. The output shaft of the motor 702 extends vertically downward and is connected to the horizontally arranged rotating plate 708. The motor 702 drives the rotating plate 708 to rotate in a circular motion. The connecting plate 709 has a rod-like structure. One end of the connecting plate 709 is rotatably connected to the edge of the rotating plate 708, and the other end is rotatably connected to the side wall of the spray pipe 705. The connecting plate 709 converts the rotational motion of the rotating plate 708 into the reciprocating linear motion of the spray pipe 705 on the guide rail 703, thereby achieving a wide-range, dead-angle-free spraying effect.

[0033] The anti-scalding connector mechanism 8 is connected to the rising film evaporator 2 and is used for detachable connection with the external air inlet pipe 807. The anti-scalding connector mechanism 8 includes a threaded connector 801 as the main body. The internal cavity of the threaded connector 801 houses key components for achieving automatic sealing, including a sealing head 803 and a spring 802. The spring 802 is located behind the sealing head 803 and always provides a forward pushing force to the sealing head 803.

[0034] The intake pipe 807, which mates with the threaded connector 801, is equipped with a structure for performing opening and closing operations. An unlocking head 805 is integrally formed at the front end of the intake pipe 807. The shape and size of the unlocking head 805 are adapted to the rear end of the sealing head 803. In the assembled state, when the intake pipe 807 is screwed into the threaded connector 801 through the handle 806 fixed on its outer wall, the unlocking head 805 of the intake pipe 807 will move forward and press against the sealing head 803, overcoming the elastic force of the spring 802, causing the sealing head 803 to move backward, thereby opening the steam passage. In the disassembled state, when the intake pipe 807 is unscrewed, the unlocking head 805 retracts, the pressure applied to the sealing head 803 disappears, and the spring 802 will immediately push the sealing head 803 forward to reset, tightly sealing the passage. This ensures that the passage of high-temperature steam can be automatically and reliably cut off at the moment of disconnection, thereby preventing steam leakage accidents.

[0035] An annular sealing strip 804 is installed on the front end of the sealing head 803 facing the unlocking head 805. At the same time, an annular valve seat that mates with the sealing strip 804 is formed inside the threaded joint 801. When the sealing head 803 is reset forward under the action of the spring 802, the sealing strip 804 will be pressed tightly onto the annular valve seat, forming a more reliable and durable sealing interface.

[0036] To improve the uniformity of spray coverage, multiple nozzles 706 are spaced apart on the wall of the spray pipe 705. After the recovered solvent is distributed to the multiple nozzles 706 through the spray pipe 705, it can form a wide atomized or linear spray band. Combined with the reciprocating motion of the spray pipe 705 itself, it ensures that the material inside the shell 1 of the horizontal leachate is uniformly wetted without dead angles.

[0037] A protective shell 701 is also fixed to the outside of the motor 702. The protective shell 701 can effectively prevent dust, liquid splashes and other substances that may occur in the production environment from damaging the motor 702, and ensure the long-term stable operation of the equipment.

[0038] To facilitate operation of the anti-scalding connector mechanism 8, a handle 806 is fixed on the outer wall of the air inlet pipe 807 for easy manual turning. Operators can easily screw the air inlet pipe 807 in and out by holding the handle 806 without the need for additional tools.

[0039] One end of the connecting plate 709 is rotatably connected to the edge of the rotating plate 708 via a pin, while the other end is rotatably connected to the connecting lug on the side wall of the spray pipe 705, ensuring effective torque transmission.

[0040] To ensure the smooth reciprocating motion of the spray pipe 705, the slider 704 is fixed to the top outer wall of the spray pipe 705. The outline of the slider 704 is designed to slide in conjunction with the inner wall groove of the guide rail 703, for example, by adopting a "T"-shaped or "V"-shaped guide rail slider structure to provide stable support and precise guidance.

[0041] The lower part of the rising film evaporator 2 is also connected to a condensate pipe 9 for draining condensate, which can promptly drain the water formed after the steam is condensed from the system to avoid affecting the evaporation efficiency.

[0042] Working principle: When spraying is required, motor 702 starts and drives rotating plate 708 to rotate. Since one end of connecting plate 709 is connected to rotating plate 708 and the other end is connected to spray pipe 705 which is restricted to linear movement by guide rail 703, the rotational motion of rotating plate 708 is converted into reciprocating linear motion of spray pipe 705 along guide rail 703 through connecting plate 709. Solvent recovered from separator 3 is continuously supplied to moving spray pipe 705 through return pipe 6 and connecting hose 707, and then evenly sprayed on material through multiple nozzles 706 on spray pipe 705. Through the reciprocating motion of spray pipe 705, a large-area, no-dead-angle coverage of the entire internal space of horizontal leachate shell 1 is achieved.

[0043] When heating of the rising film evaporator 2 is required, the operator holds the handle 806 and screws the inlet pipe 807 into the threaded connector 801. During the screwing process, the unlocking head 805 at the front end of the inlet pipe 807 will press forward and push open the sealing head 803, compressing the spring 802 behind the sealing head 803, thereby opening the steam passage. When it is necessary to disassemble the inlet pipe 807, the handle 806 is rotated in the opposite direction, and the unlocking head 805 moves backward with the inlet pipe 807. The pressure on the sealing head 803 disappears, and the spring 802 immediately releases its elastic force, pushing the sealing head 803 forward to reset. This causes the sealing strip 804 at the front end of the sealing head 803 to be tightly pressed against the annular valve seat inside the threaded connector 801, thereby instantly and automatically cutting off the steam passage.
