Description

Technical Field

[0001] The present invention relates to the technical field of soap base manufacturing, and in particular to a device and method for efficiently drying a soap base after washing. Background Art

[0002] During the soap base production process, after the saponification reaction is complete, further separation and drying are required. Separating the soap and glycerin: The upper layer of soap is separated from the lower layer of glycerin-water solution by standing or centrifuging. The resulting soap still contains a certain amount of water and impurities and requires further processing. Drying the soap: The separated soap is dried to remove the moisture. Drying methods can include air drying, oven drying, or vacuum drying to reduce the soap's moisture content to an appropriate level (generally below 10%).

[0003] However, during the drying process of the soap base, if a strong drying hot air flow is used to directly take away the water evaporated from the surface of the soap base, the surface water evaporates quickly, while the internal water diffuses slowly, resulting in the formation of a hard shell on the surface, which is not conducive to the timely discharge of internal water.

[0004] In the face of the above problems, the existing solution can only be to alleviate the evaporation of surface moisture by adopting a slow, relatively low-temperature drying hot air flow method, but this will undoubtedly reduce the overall drying efficiency of the soap base.

[0005] In summary, how to avoid rapid evaporation of water on the soap base surface and ensure the overall drying efficiency of the soap base has become a problem that needs to be solved. Summary of the Invention

[0006] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The present invention provides a high-efficiency drying device for soap base after washing, comprising a drying tank for holding the soap base to be dried, a heater being arranged on the ring side of the drying tank, the heater being provided with a plurality of heating rings equally spaced along the vertical direction, a lifting plate being movably arranged at the opening of the drying tank, and a lifter being arranged above the lifting plate for driving the lifting plate to move vertically.

[0008] A flat sponge piece is arranged below the lifting plate and is located above the surface of the soap base, wherein an evaporation gap is formed between the flat sponge piece and the surface of the soap base, and a hot air flow area is formed between the flat sponge piece and the lifting plate. An evaporation humidity sensor for detecting the humidity in the hot air flow area is fixedly installed on the bottom surface of the lifting plate, and a vertical air flow rising port is opened at the center of the flat sponge piece.

[0009] The center of the lift plate houses an air collection pipe connected to the hot air flow area. This pipe is connected to an air flow pump via a return air line. A heating and dehumidifying mechanism is connected downstream of the pump via an air pipe. Multiple, evenly spaced, wide-mouthed air outlets are located at the edge of the lift plate. The outlet of the heating and dehumidifying mechanism is connected to an air intake line, which in turn is connected to the wide-mouthed air outlets. A return air humidity sensor is located within the pipe, and a distance sensor is located at its base, pointing vertically downward and facing the rising air flow outlet.

[0010] As a preferred technical solution of the drying equipment of the present invention: a lifting frame is fixedly installed on the top of the lifting plate, and the lifter is equipped with a lifting shaft facing vertically downward, and the lifting shaft is fixedly connected to the lifting frame.

[0011] As a preferred technical solution for the drying apparatus of the present invention, a plurality of lower connecting rods are fixedly connected to the bottom surface of the lifting plate, the bottom ends of which are fixedly connected to an outer frame structure, and the flat sponge member is placed within the outer frame structure. The outer periphery of the outer frame structure is provided with a piston ring structure that slides in contact with the inner wall of the drying tank.

[0012] As a preferred technical solution of the drying equipment of the present invention: a plurality of ring-side air inlets are provided at the bottom of the ring side of the gas collecting pipe, and the distance sensor is fixed on the lower side of the bottom plate of the gas collecting pipe.

[0013] As a preferred technical solution of the drying equipment of the present invention: an inlet air temperature sensor is provided at the air inlet end of the heating and dehumidifying mechanism, and an outlet air temperature sensor is provided at the air outlet end of the heating and dehumidifying mechanism.

[0014] As a preferred technical solution of the drying device of the present invention, the area enclosed by the distribution positions of the multiple wide-mouth air outlet nozzles matches the distribution range of the flat sponge members.

[0015] As a preferred technical solution of the drying device of the present invention: an alloy support skeleton for maintaining the shape of the flat sponge member is provided inside or on the outer surface of the flat sponge member.

[0016] The present invention provides a method for efficiently drying a soap base after washing, comprising the following steps:

[0017] In the first step, a fixed amount of soap base is gently injected into the drying tank. After standing for a period of time, the lifter drives the lifting plate and the flat sponge to move downward. When the distance sensor detects that the distance to the surface of the soap base is L, the lifting plate stops descending. At this time, the vertical height of the evaporation gap is the preset standard parameter.

[0018] In the second step, based on the position information of the flat sponge part driven by the lifter and the distance information of the soap base surface detected by the distance sensor, the heating ring below the horizontal position of the soap base surface is determined and the heating ring is driven to start working.

[0019] In the third step, the moisture in the soap base evaporates due to heat and enters the evaporation gap. The flat sponge absorbs the moisture in the evaporation gap. At the same time, the excess humid air in the evaporation gap is discharged upward from the air flow rising port of the flat sponge into the hot air flow area.

[0020] In the fourth step, the air flow pump and heating and dehumidification mechanism are started, and the air flow discharged into the hot air flow area enters the air collecting pipe. The return air humidity sensor in the air collecting pipe detects the real-time humidity of the intake air. The heating and dehumidification mechanism adjusts the working power according to the real-time humidity of the intake air, reduces the humidity of the air flow, and re-injects it into the hot air flow area from the intake pipe and the wide-mouth air outlet.

[0021] Step five: When the distance sensor detects that the surface of the soap base is descending, the lifter drives the lifting plate to descend synchronously until the distance sensor detects that the distance to the surface of the soap base is L. At the same time, the heating ring above the horizontal position of the soap base surface stops working.

[0022] Step 6, Humidity Condition 1: When the evaporative humidity sensor or the return air humidity sensor detects that the humidity in the hot air flow area is lower than the preset reference humidity, the heater stops heating and the system delay module activates. If humidity condition 1 is met within the preset duration T, heating and drying of the soap base in the drying tank is determined to be complete, and the airflow pump and heating and dehumidification mechanism both stop operating.

[0023] In the present invention, during the soap base drying process, the system presets an airflow reference temperature, and when the heating and dehumidifying mechanism dehumidifies the circulating airflow, it heats the airflow to ensure that the airflow temperature is not lower than the airflow reference temperature.

[0024] Compared with the existing technology, the beneficial effects of the present invention are:

[0025] 1. In the present invention, a flat sponge member is arranged on the surface of the soap base. The flat sponge member absorbs the moisture released from the surface of the soap base, so that a moist medium layer is formed between the surface of the soap base and the dry airflow. The dry airflow can quickly discharge the moisture absorbed by the flat sponge member (the moisture here is also the moisture released from the surface of the soap base), avoiding direct contact between the dry airflow and the surface of the soap base. In addition, an evaporation gap for dissipating the moisture of the soap base is formed between the surface of the soap base and the flat sponge member, and an air flow rising port is opened at the center of the flat sponge member to facilitate the normal discharge of excess moisture in the evaporation gap, thereby preventing the rapid evaporation of moisture on the surface of the soap base to form a hard crust and creating favorable conditions for the discharge of internal moisture.

[0026] 2. The present invention allows the lifter to drive the flat sponge member down to the corresponding horizontal position based on the distance information of the soap base surface detected by the distance sensor, determines and drives the heating ring below the horizontal position of the soap base surface to work, ensures heating efficiency, and reduces heating and drying energy consumption to a certain extent.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] Example 1: The present invention designs a highly efficient drying device for soap base after washing. Figure 1 , equipped with a drying tank 1, a heater 3, a lifting plate 4, a lifter 5, a flat sponge member 8, an air flow pump 14, a heating and dehumidifying mechanism 15 and other components. The specific structure is as follows:

[0034] Drying tank 1: Figure 1 , used to hold the soap base 2 to be dried, and is the carrying container for the entire drying process.

[0035] Heater 3: As Figure 1 、 Figure 2 The heater 3 is equipped with a plurality of heating rings 301 spaced evenly in the vertical direction. The heating power of the heating rings 301 increases in ascending order, so that the soap base 2 is gradually heated from the bottom to the top, which is conducive to the uniform evaporation of the internal water and avoids local overheating.

[0036] Lifting plate 4: Figure 1 、 Figure 4 The top is fixed with a lifting frame 401, which can be moved vertically under the drive of the lifter 5 to adjust the distance between the flat sponge 8 and the surface of the soap base 2. The lifting frame 401 is fixedly connected to the lifting shaft 501 of the lifter 5, and plays the role of connecting the lifting plate 4 and the lifter 5.

[0037] Lifter 5: As Figure 1 , is equipped with a vertical downward lifting shaft 501 to drive the lifting plate 4 to move vertically. The lifting shaft 501 is fixedly connected to the lifting frame 401 to realize the driving of the lifting device 5 to the lifting plate 4.

[0038] Lower link 6: Figure 1 、 Figure 2 The bottom surface of the lifting plate 4 is fixedly connected to multiple lower connecting rods 6, which are used to connect the lifting plate 4 and the outer frame structure 7.

[0039] Outer frame structure 7: such as Figure 1 、 Figure 2 The bottom ends of multiple lower connecting rods 6 are fixedly connected to the outer frame structure 7, and the flat sponge member 8 is placed inside the outer frame structure 7. The outer periphery of the outer frame structure 7 is provided with a piston ring structure that is in sliding contact with the inner wall of the drying tank 1, which plays a role in supporting the flat sponge member 8 and ensuring the sealing of the hot air flow area 10 to prevent air leakage from the edge.

[0040] Flat sponge piece 8: Figure 1 、 Figure 3 , located above the surface of the soap base 2, the interior or outer layer is provided with an alloy support skeleton for maintaining the shape of the flat sponge part 8. An evaporation gap 9 is formed between it and the surface of the soap base 2, and a hot air flow area 10 is formed between it and the lifting plate 4. It can absorb the moisture released by the surface of the soap base 2, and form a moist medium layer between the surface of the soap base 2 and the dry air flow, so as to avoid direct contact between the dry air flow and the surface of the soap base 2, prevent the formation of a hard shell on the surface, and accelerate the dissipation of moisture through its own adsorption effect. The air flow rising port 801 is opened at the center of the flat sponge part 8, and the excess humid air flow in the evaporation gap 9 can be discharged upward into the hot air flow area 10 through this port, so as to ensure smooth air flow in the evaporation gap 9 and prevent water vapor accumulation.

[0041] Evaporation gap 9: as Figure 1 、 Figure 2 、 Figure 3 , located between the flat sponge piece 8 and the surface of the soap base 2, is the space for the water in the soap base 2 to evaporate.

[0042] Thermal area 10: Figure 2 、 Figure 3 , located between the flat sponge member 8 and the lifting plate 4, and is used to accommodate the moist airflow discharged from the evaporation gap 9 and the dry airflow processed by the heating and dehumidification mechanism 15.

[0043] Gas collecting pipe 11: Figure 1 、 Figure 3 、 Figure 4 Located at the center of the lifting plate 4, it communicates with the hot air flow area 10. Multiple ring-shaped air inlets 1101 are located at the bottom of the ring side surface to collect airflow from the hot air flow area 10. The multiple ring-shaped air inlets 1101 at the bottom of the ring side surface of the air collecting pipe 11 facilitate the entry of airflow from the hot air flow area 10 into the air collecting pipe 11. A distance sensor 20 is located at the bottom of the air collecting pipe 11, with a vertical downward detection direction and aligned with the air flow riser 801. This distance sensor is used to detect the distance from the surface of the soap base 2, thereby controlling the raising and lowering of the lifting plate 4.

[0044] Return air humidity sensor 12: Figure 1 , configured in the air collecting pipe 11, detects the real-time humidity of the intake air and provides data basis for the heating and dehumidification mechanism 15 to regulate the working power.

[0045] Return air line 13: Figure 1 , connect the air collecting pipe 11 and the air flow pump 14 so that the air flow collected by the air collecting pipe 11 can be delivered to the air flow pump 14. The air flow pump 14 delivers the air flow collected by the air collecting pipe 11 to the heating and dehumidification mechanism 15.

[0046] Heating and dehumidifying mechanism 15: Figure 1 、 Figure 2 The operating power is adjusted based on the humidity detected by the return air humidity sensor 12, reducing the humidity of the airflow. At the same time, the circulating airflow is heated to ensure that the airflow temperature is not lower than the airflow reference temperature preset by the system, so that the dry airflow can continuously and efficiently remove moisture. The inlet air temperature sensor 16 is configured at the air inlet end of the heating and dehumidification mechanism 15 to monitor the temperature of the airflow entering the heating and dehumidification mechanism 15. The outlet air temperature sensor 17 is configured at the air outlet end of the heating and dehumidification mechanism 15 to monitor the temperature of the airflow discharged from the heating and dehumidification mechanism 15, so as to better control the heating and dehumidification process and ensure that the airflow temperature meets the drying requirements. The outlet end of the heating and dehumidification mechanism 15 is connected to the air inlet pipeline 18, which conveys the treated dry airflow to the wide-mouth air outlet nozzle 19.

[0047] Wide mouth air outlet 19: Figure 1 、 Figure 2 A plurality of wide-mouth air outlet nozzles 19 are arranged at equal intervals in the edge area of ​​the lifting plate 4. The dried air flow is re-injected into the hot air flow area 10 through the wide-mouth air outlet nozzles 19, realizing air flow recycling and improving drying efficiency. The area surrounded by the distribution positions of the plurality of wide-mouth air outlet nozzles 19 is coordinated with the distribution range of the flat sponge piece 8, which can evaporate and take away the heat and moisture of the flat sponge piece 8 more comprehensively.

[0048] Evaporation humidity sensor 21: Figure 1It is fixedly installed on the bottom surface of the lifting plate 4 and is used to detect the humidity of the hot air flow area 10, so as to judge the moisture content of the hot air flow area 10 during the drying process and provide data basis for the subsequent control equipment work.

[0049] Example 2: The present invention designs a method for efficiently drying soap base after washing, the specific contents are as follows:

[0050] Step 1: Slowly inject a fixed amount of soap base 2 into the drying tank 1. After standing for a period of time, the lifter 5 drives the lifting plate 4 and the flat sponge part 8 to move downward. When the distance sensor 20 detects that the distance to the surface of the soap base 2 is L, the lifting plate 4 stops descending. At this time, the vertical height of the evaporation gap 9 reaches the preset standard parameter. This step can ensure that the evaporation gap 9 is of appropriate size, which is conducive to water evaporation and air flow. Among them, the lifter 5 adjusts the distance between the flat sponge part 8 and the surface of the soap base 2 by driving the lifting plate 4 to move. The distance sensor 20 is used to measure the distance to the surface of the soap base 2, thereby controlling the position of the lifting plate 4. The evaporation gap 9 is the key space for the evaporation of water from the soap base 2.

[0051] Step 2: Based on the position information of the flat sponge member 8 driven downward by the lifter 5 and the distance information from the surface of the soap base 2 detected by the distance sensor 20, the heater ring 301 is determined to be below the horizontal position of the soap base 2 and is activated to start operation. Here, the lifter 5 and the distance sensor 20 provide data to determine the operating status of the heater ring 301, which is responsible for heating the soap base 2.

[0052] Step 3: The moisture in the soap base 2 evaporates due to heat and enters the evaporation gap 9. The flat sponge member 8 absorbs the moisture in the evaporation gap 9. At the same time, the excess moist airflow in the evaporation gap 9 is discharged upward from the airflow riser 801 of the flat sponge member 8 into the hot airflow area 10. The adsorption of the flat sponge member 8 and the exhaust of the airflow riser 801 achieve the initial collection and discharge of moisture. The flat sponge member 8 forms a moist medium layer between the surface of the soap base 2 and the dry airflow, preventing direct contact between the dry airflow and the surface of the soap base 2. The airflow riser 801 provides a discharge channel for the moist airflow in the evaporation gap 9, and the hot airflow area 10 is used to accommodate and discharge the moist airflow.

[0053] Step 4: The airflow pump 14 and the heating and dehumidifying mechanism 15 are started, and the airflow discharged into the hot airflow area 10 enters the air collecting pipe 11. The return air humidity sensor 12 in the air collecting pipe 11 detects the real-time humidity of the incoming air. The heating and dehumidifying mechanism 15 adjusts the operating power according to the real-time humidity of the incoming air, reduces the humidity of the airflow, and re-injects the airflow into the hot airflow area 10 through the air intake pipe 18 and the wide-mouth air outlet nozzle 19. This step realizes the cyclic dehumidification and heating of the airflow, ensures the drying capacity of the dry airflow, and continuously removes the moisture discharged by the soap base 2. The airflow pump 14 is responsible for conveying the airflow, the heating and dehumidifying mechanism 15 dehumidifies and heats the airflow, the air collecting pipe 11 collects the airflow from the hot airflow area 10, the return air humidity sensor 12 detects the humidity of the airflow, and the air intake pipe 18 and the wide-mouth air outlet nozzle 19 return the treated airflow to the hot airflow area 10.

[0054] Step 5: When distance sensor 20 detects the surface of soap base 2 descending, lifter 5 drives lift plate 4 downward synchronously until distance sensor 20 detects a distance L from the surface of soap base 2. Simultaneously, heating ring 301, located above the surface of soap base 2, stops operating. This step allows the distance between flat sponge member 8 and soap base 2 to be adjusted in real time based on the drying condition of soap base 2, maintaining the optimal evaporation gap 9 and simultaneously stopping heating in unnecessary areas, saving energy.

[0055] Step 6: When the evaporative humidity sensor 21 or the return air humidity sensor 12 detects that the humidity in the hot air flow area 10 is below the preset reference humidity, the heater 3 stops heating and the system delay module activates. If humidity condition 1 is met within the preset duration T, the soap base 2 in the drying tank 1 is considered to be completely heated and dried, and the air flow pump 14 and the heating and dehumidification mechanism 15 both stop operating. This humidity determination and delay confirmation ensure that the soap base 2 reaches the drying requirement, preventing over-drying or under-drying.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
