Description

Technical Field

[0001] The utility model relates to the technical field of drying devices, in particular to a drying device for detecting white wine precipitate. Background Art

[0002] White wine is a distilled wine prepared with grain as the main raw material, and Daqu, Xiaoqu, bran koji, enzyme preparations, yeast and the like as saccharification and fermentation starters, through the processes of cooking, saccharification, fermentation, distillation, aging and blending. During the production and processing of white wine, precipitates are generated due to factors including raw materials and processes, temperature changes, storage conditions, additives and blending. To ensure the quality of white wine, it is necessary to detect the precipitates in white wine and determine the quantity and types of the precipitates. The detection of white wine precipitate mainly involves physical property observation, chemical component analysis, microbial detection and pollutant screening, which needs to be carried out by professional equipment such as microscopes and spectrometers. When detecting white wine precipitate, it is required to dry a certain amount of white wine using an electric drying device, and detect the precipitate after obtaining the same.

[0003] During the use of electric drying devices, in order to improve drying efficiency, a negative pressure device is mostly used to pump out the gas in the drying chamber, reduce the internal air pressure, thereby lowering the boiling point of the liquid and improving the drying efficiency. However, in the use process, how to accurately control the pressure in the drying chamber is a difficult problem: it is prone to the problem that the power of the negative pressure device is too high, leading to excessively fast heat loss in the drying chamber, or excessive air pressure affects the liquid evaporation efficiency. The conventional design idea adopts an electronic barometer and an intelligent control system for linkage control, which requires a single-chip microcomputer and a large number of electronic devices for control, resulting in relatively high cost. Contents of the Utility Model

[0004] The first technical problem to be solved by the utility model is to provide a drying device for detecting white wine precipitate, so as to realize accurate control of the pressure in the drying chamber in a relatively lower-cost manner.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a drying device for detecting sediment in baijiu (Chinese liquor), comprising a main body and a controller. The main body has a drying chamber inside, and is equipped with a negative pressure device to create a negative pressure state inside the drying chamber. The negative pressure device is electrically connected to the controller and is equipped with a suction speed regulating device. The main body has an openable and closable sealed door on the front side of the drying chamber. A placement mechanism is provided inside the drying chamber. A first control mechanism, a pressure testing mechanism, and a second control mechanism are installed on the top of the drying chamber. The pressure testing mechanism includes a vertically arranged mounting cylinder. The bottom end of the mounting cylinder is fixedly connected to the outer wall of the top of the main body. The bottom end of the inner cavity of the mounting cylinder is connected to the inside of the drying chamber. A pressure spring with a vertically arranged axis is fixedly connected to the inner wall of the bottom end of the mounting cylinder. A sealing piston is fixedly connected to the top of the pressure spring. The sealing piston is in sealed contact with the inner wall of the mounting cylinder and forms a sliding contact. The sealing piston is fixedly connected to a vertically arranged connecting rod at its top, and the mounting cylinder is fixedly connected to an upwardly extending mounting column at its top. A sliding block that can slide up and down is installed on the inner wall of the mounting column, and the bottom end of the sliding block is fixedly connected to the top of the connecting rod. Two vertical grooves are spaced apart along the circumference of the mounting column on its side. A first control mechanism and a second control mechanism are respectively located on the outer periphery of the mounting column and correspond one-to-one with the vertical grooves. Both the first and second control mechanisms include a stroke control switch that works in conjunction with the sliding block. The stroke control switch is electrically connected to the controller and slides within its corresponding vertical groove.

Each stroke control switch is equipped with a screw-nut kinematic pair that drives it to move along the vertical groove. The screw input end of the screw-nut kinematic pair is equipped with a rotary operating structure.

[0006] As a further preferred embodiment of this utility model: the travel control switch includes a switch mounting block, and a blind hole for switch mounting is provided on the side end face of the switch mounting block facing the slider. The axis of the blind hole for switch mounting is horizontally set. A return spring and a buffer spring are fixedly connected to the bottom wall of the blind hole for switch mounting, and a pressure block is fixedly connected to the other end of the return spring. A tactile switch is fixedly connected to the other end of the buffer spring. Both the buffer spring and the tactile switch are located inside the return spring. The pressure block slides in cooperation with the inner cavity side wall of the blind hole for switch mounting. A roller is movably sleeved on the end of the pressure block away from the return spring. A roller is movably sleeved on the outer end face of the slider. When both the buffer spring and the return spring are in their natural state, there is a gap between the pressure block and the tactile switch. When the roller moves up and down with the slider, the roller can squeeze the roller and drive the pressure block to touch the tactile switch, so that the tactile switch receives a sensing signal.

[0007] As a further preferred embodiment of this utility model: the lead screw and nut kinematic pair includes a lead screw and a fixed block. The upper and lower ends of the lead screw are rotatably connected to the fixed block, and the fixed block is fixedly set relative to the mounting post. The stroke control switch includes a switch mounting block, and the middle part of the lead screw is threadedly connected to the switch mounting block. The rotary operating structure includes a worm gear and a worm that cooperate with each other. The worm gear is coaxially fixedly set at the upper end of the lead screw, and the axis of the worm is set horizontally. The worm is rotatably mounted on the fixed block through a support seat, and a rotary tool joint is provided at the end face of the worm. The rotary tool joint is preferably a hexagonal groove.

[0008] As a further preferred embodiment of this utility model: the outer surface of the mounting column has a scale at the outer end face of the vertical slide groove corresponding to the position of the travel control switch.

[0009] As a further preferred embodiment of this utility model: a lower sealing plate with a central through hole is fixedly installed at the bottom of the inner cavity of the mounting cylinder, the central through hole of the lower sealing plate is used to connect to the inside of the drying chamber, and a pressure spring is fixedly installed on the upper surface of the lower sealing plate; an upper sealing plate with a central through hole is fixedly installed at the top of the inner cavity of the mounting cylinder, the central through hole of the upper sealing plate is used for the connecting rod to pass through, and a mounting column is fixedly installed at the top of the upper sealing plate.

[0010] As a further preferred embodiment of this utility model: the placement mechanism includes horizontally arranged wire mesh plates, multiple wire mesh plates are arranged at intervals along the vertical direction, and the side end faces of the wire mesh plates are fixedly connected to the inner side wall of the drying chamber.

[0011] As a further preferred embodiment of this utility model: the top of the mesh plate is provided with a placement box, a positioning block, and a guide block. The positioning block is fixedly disposed on the left and right sides of the rear end of the upper surface of the mesh plate, and the guide block is fixedly disposed on the left and right sides of the front end of the upper surface of the mesh plate. The placement box is slidably disposed relative to the upper surface of the mesh plate in the front-back direction. The left and right sides of the placement box form a guiding engagement with the guide block, and the left and right sides of the rear end of the placement box form a limiting engagement with the positioning block respectively. The front and rear ends of the left and right sides of the placement box are fixedly connected with elastic clips. The elastic clip located at the front end of the placement box is used to make the slots on the placement box and the guide block form a locking engagement, and the elastic clip located at the rear end of the placement box is used to make the slots on the placement box and the positioning block form a locking engagement.

[0012] The beneficial effects of this utility model are as follows: By moving the stroke control switch along the vertical slide groove according to usage requirements, the stroke control switch of the first control mechanism is positioned at the position corresponding to the lowest air pressure value inside the drying chamber, and the stroke control switch of the second control mechanism is positioned at the position corresponding to the highest air pressure value inside the drying chamber. During the drying process, the steam generated is discharged through the negative pressure device. As the air pressure inside the drying chamber decreases, the air pressure on the sealing piston increases, pushing the sealing piston downward, thereby causing the slider to contact the stroke control switch of the first control mechanism. The stroke control switch receives a sensing signal and transmits it to the controller, reducing the power of the negative pressure device and reducing the suction speed of the negative pressure device until the air pressure inside the drying chamber increases. The pressure spring pushes the sealing piston upward, causing the slider to separate from the stroke control switch of the first control mechanism. When the air pressure inside the drying chamber is too high, the pressure spring pushes the sealing piston upward, causing the slider to contact the stroke control switch of the second control mechanism. The controller controls the negative pressure device to increase its power and speed up the suction speed of the negative pressure device, reducing the air pressure inside the drying chamber, thereby ensuring that the air pressure inside the drying chamber is within a suitable range for drying, which is beneficial to improving drying efficiency. This invention generally employs a conventional limit switch. In a preferred embodiment, a conventional tactile switch is sufficient. Regardless of the type of limit switch used, the controller employs a conventional information processing chip, making it a commonly used information processing device. This invention achieves accurate pressure control within the drying chamber at a relatively lower cost. Furthermore, when adjusting the position of the limit switch, this invention connects the rotating tool to the rotating tool connector at the end face of the worm gear, causing the worm gear to rotate. The worm gear and worm wheel then interact to drive the lead screw, which, through a threaded structure, moves the limit switch up and down along a vertical groove. This facilitates adjustment, improves equipment flexibility, and the worm gear mechanism formed by the worm gear and worm wheel has good self-locking properties, enhancing the reliability of the limit switch displacement adjustment mechanism.

Detailed Implementation

[0015] 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.

[0016] Please see Figures 1-6 This utility model includes a main body 1 and a controller. The main body 1 has a drying chamber 101 inside. The main body 1 is equipped with a negative pressure device 102 for creating a negative pressure state inside the drying chamber 101. The negative pressure device 102 is electrically connected to the controller and is equipped with a suction speed regulating device. The main body 1 has an openable and closable sealing door 103 on the front side of the drying chamber 101. A placement mechanism 4 is provided inside the drying chamber 101. The main body 1 can generally be a conventional electric drying device, and the negative pressure device 102 can generally be a conventional vacuum pump. The negative pressure device 102 can be installed in a suitable position on the main body 1. In the preferred embodiment shown in the attached drawings, the negative pressure device 102 is fixedly installed at the top of the main body 1. The suction speed regulating device can be implemented using various conventional technologies, such as designing a speed regulating valve in the pipeline or setting a power regulator. The suction speed is regulated by adjusting the power of the negative pressure device 102 during actual operation. The embodiments described later use this method of adjusting the power of the negative pressure device 102 during actual operation to achieve suction speed regulation. The sealing door 103 can be installed using various conventional techniques, such as rotating or sliding opening, as long as it ensures that the drying chamber 101 is sealed when the sealing door 103 is closed. In the preferred embodiment shown in the attached drawings, the sealing door 103 is rotatably set by a movable pin.

[0017] In this invention, the main body 1 of the equipment is further equipped with a first control mechanism 2, a pressure testing mechanism 3, and a second control mechanism 5 at the top of the drying chamber 101. The pressure testing mechanism 3 includes a vertically arranged mounting cylinder 301, the bottom end of which is fixedly connected to the outer wall of the top of the main body 1. The bottom end of the inner cavity of the mounting cylinder 301 is connected to the interior of the drying chamber 101. A pressure spring 308 with a vertically arranged axis is fixedly connected to the inner wall of the bottom end of the mounting cylinder 301. To facilitate the installation of the pressure testing mechanism 3, a lower sealing plate with a central through hole can generally be fixedly installed at the bottom end of the inner cavity of the mounting cylinder 301. The central through hole of the lower sealing plate is used to connect to the interior of the drying chamber 101. The inner diameter of the central through hole of the lower sealing plate is smaller than the inner diameter of the pressure spring 308. The pressure spring 308 is fixedly installed on the upper surface of the lower sealing plate. In some alternative embodiments, the lower end of the pressure spring 308 can also be directly fixedly connected to the outer wall of the top of the main body 1.

[0018] A sealing piston 304 is fixedly connected to the top of the pressure spring 308. The sealing piston 304 is in tight contact with the inner wall of the mounting cylinder 301 and forms a sliding fit. A vertically arranged connecting rod 307 is fixedly connected to the top of the sealing piston 304. An upwardly extending mounting post 302 is fixedly connected to the top of the mounting cylinder 301. A sliding block 306 (equivalent to the mounting post 302 being a hollow column structure) is installed on the inner wall of the mounting post 302. The bottom end of the sliding block 306 is fixedly connected to the top of the connecting rod 307. To facilitate the fixed installation of the mounting post 302, an upper sealing plate with a central through hole can generally be fixedly installed at the top of the inner cavity of the mounting cylinder 301. The central through hole of the upper sealing plate is used for the connecting rod 307 to pass through, and the mounting post 302 is fixedly installed at the top of the upper sealing plate.

[0019] The mounting post 302 has two vertical sliding grooves 303 spaced apart along its circumference on its side. The first control mechanism 2 and the second control mechanism 5 are respectively located on the outer periphery of the mounting post 302 and correspond one-to-one with the vertical sliding grooves 303. That is, one vertical sliding groove 303 corresponds to the first control mechanism 2, and the other vertical sliding groove 303 corresponds to the second control mechanism 5. The two vertical sliding grooves 303 can be arranged side by side with a certain lateral spacing. The preferred option is that the two vertical sliding grooves 303 are symmetrically arranged on both sides of the mounting post 302. Both the first control mechanism 2 and the second control mechanism 5 include a stroke control switch 202 that works in conjunction with the slider 306 (i.e., the slider 306 can touch the stroke control switch 202 and generate a sensing signal when it moves up and down). The stroke control switch 202 is electrically connected to the controller and is slidably installed in its corresponding vertical slide groove 303. The stroke control switch 202 of the first control mechanism 2 is located in the area below the slider 306, and the stroke control switch 202 of the second control mechanism 5 is located in the area above the slider 306. The stroke control switch 202 is equipped with a lead screw and nut kinematic pair that drives it to move along the vertical slide groove 303. The lead screw input end of the lead screw and nut kinematic pair is equipped with a rotary operation structure.

[0020] During implementation, according to usage requirements, the stroke control switch 202 of the first control mechanism 2 is moved along the vertical slide 303, so that the stroke control switch 202 of the first control mechanism 2 is located at the position corresponding to the lowest air pressure value inside the drying chamber 101, and the stroke control switch 202 of the second control mechanism 5 is located at the position corresponding to the highest air pressure value inside the drying chamber 101. A certain amount of liquor sample is placed into the placement mechanism 4 through a storage container (e.g., placement box 402), the sealing door 103 is closed, the negative pressure device 102 is activated, the air inside the drying chamber 101 is extracted, and the air pressure inside the drying chamber 101 is reduced. At the same time, the heating device inside the drying chamber 101 is activated to heat the chamber. Steam generated during the drying process is discharged through the negative pressure device 102. As the air pressure inside the drying chamber 101 decreases, the air pressure on the sealing piston 304 increases, pushing the sealing piston. 304 moves downward, causing slider 306 to contact the stroke control switch 202 of the first control mechanism 2. The stroke control switch 202 generates a sensing signal that is transmitted to the controller, reducing the power of the negative pressure device 102 and the air extraction speed of the negative pressure device 102 until the air pressure inside the drying chamber 101 increases. The pressure spring 308 pushes the sealing piston 304 upward and separates it from the stroke control switch 202 of the first control mechanism 2. When the air pressure inside the drying chamber 101 is too high, the pressure spring 308 pushes the sealing piston 304 upward, causing slider 306 to contact the stroke control switch 202 of the second control mechanism 5. The controller controls the negative pressure device 102 to increase its power and speed up the air extraction speed of the negative pressure device 102, thereby reducing the air pressure inside the drying chamber 101 and drying the air within a suitable range.

[0021] This utility model generally employs a conventional limit control switch 202, and its controller uses a conventional information processing chip, belonging to commonly used information processing devices. It is understood that using the sensing signal from the limit control switch 202 to control the actuator's action is a conventional control method. This utility model does not involve improvements to the computer program. The key technical points of this utility model lie in the specific installation structure of the first control mechanism 2, the pressure testing mechanism 3, and the second control mechanism 5, which fall under the protection of this utility model.

[0022] To ensure the simple and reliable structure of the travel control switch 202, in a preferred embodiment, the travel control switch 202 includes a switch mounting block 2021. A blind hole for switch mounting is provided on the side of the switch mounting block 2021 facing the slider 306. The axis of the blind hole is horizontal. A return spring 2022 and a buffer spring 2023 (which can be essentially coaxial; in a further preferred embodiment, both the return spring 2022 and the buffer spring 2023 are coaxial with the blind hole) are fixedly connected to the bottom wall of the blind hole. A pressure block 2025 is fixedly connected to the other end of the return spring 2022, and a pressure block 2025 is fixedly connected to the other end of the buffer spring 2023. There is a tactile switch 2026, and both the buffer spring 2023 and the tactile switch 2026 are located inside the return spring 2022. The pressure block 2025 slides in conjunction with the inner wall of the blind hole for the switch mounting. A roller 2024 is movably sleeved on the end of the pressure block 2025 away from the return spring 2022, and a roller 305 is movably sleeved on the outer end face of the slider 306. When the buffer spring 2023 and the return spring 2022 are in their natural state, there is a gap between the pressure block 2025 and the tactile switch 2026. When the roller 305 moves up and down with the slider 306, the roller 305 can squeeze the roller 2024 and drive the pressure block 2025 to touch the tactile switch 2026, so that the tactile switch 2026 receives a sensing signal. The reset spring 2022 is used for the automatic reset of the roller 2024 and the pressure block 2025. The buffer spring 2023 plays a role in resetting and buffering the tactile switch 2026. The roller 305 and the roller 2024 are in rolling contact. Both the reset spring 2022 and the buffer spring 2023 can effectively play a buffering role. In the above installation structure design, the tactile switch 2026 is not easily damaged during operation.

[0023] The lead screw and nut kinematic pair is a conventional complete set of equipment. It generally includes a lead screw 203 and a fixed block 201. The upper and lower ends of the lead screw 203 are rotatably connected to the fixed block 201, which is fixed relative to the mounting post 302. The travel control switch 202 includes a switch mounting block 2021, and the middle part of the lead screw 203 is threadedly connected to the switch mounting block 2021. In a preferred embodiment, the rotary operating structure includes a cooperating worm gear 205 and a worm 204. The worm gear 205 is coaxially fixed to the upper end of the lead screw 203, and the axis of the worm 204 is horizontally positioned. The worm 204 is rotatably mounted on the fixed block 201 via a support base, and a rotary tool joint 206 is provided at the end face of the worm 204. For each lead screw 203, the fixing block 201 can be designed as an integral structure that matches the installation requirements of the lead screw 203, or it can be designed as two blocks arranged vertically opposite each other. In the preferred embodiment shown in the figure, the fixing block 201 is designed as two blocks arranged vertically opposite each other, and both fixing blocks 201 are fixedly connected to the mounting column 302. In some other embodiments, the fixing block 201 located at the lower end of the lead screw 203 can also be fixedly connected to the upper closing plate of the mounting cylinder 301, or it can be fixedly connected to the upper closing plate of the mounting cylinder 301 at the same time as being fixedly connected to the mounting column 302. During operation, by connecting the rotary tool and the rotary tool connector 206 at the end face of the worm 204, the worm 204 is rotated. The worm 204, in turn, rotates in conjunction with the worm wheel 205, driving the lead screw 203 to rotate. The lead screw 203, through its threaded structure, moves the travel control switch 202 up and down along the vertical slide groove 303, facilitating adjustment and improving equipment flexibility. Furthermore, the worm gear mechanism formed by the worm 204 and worm wheel 206 has good self-locking performance, enhancing the reliability of the travel control switch displacement adjustment mechanism. Considering structural versatility and reliability, the rotary tool connector 206 is preferably a hexagonal slot. During operation, inserting a hexagonal wrench into the hexagonal slot rotates the worm 204.

[0024] To facilitate more intuitive observation of the position of the travel control switch 202 and to make its position adjustment easier, in a preferred embodiment, the outer surface of the mounting post 302 is provided with a scale at the outer end face of the vertical slide groove 303 corresponding to the position of the travel control switch 202.

[0025] To facilitate testing and the simultaneous placement of multiple sets of liquor samples, and to ensure efficient heat transfer, in a preferred embodiment, the placement mechanism 4 includes horizontally arranged mesh plates 401. Multiple mesh plates 401 are arranged at vertical intervals, and their side surfaces are fixedly connected to the inner wall of the drying chamber 101. During the drying process, heated air can flow freely through the holes in the mesh plates 401, ensuring drying efficiency.

[0026] To facilitate the placement of liquor samples, in a preferred embodiment, the top of the mesh plate 401 is provided with a placement box 402, a positioning block 404, and a guide block 405. The positioning block 404 is fixedly disposed on the left and right sides of the rear end of the upper surface of the mesh plate 401, and the guide block 405 is fixedly disposed on the left and right sides of the front end of the upper surface of the mesh plate 401. The placement box 402 is slidably disposed relative to the upper surface of the mesh plate 401 in the front-back direction. The left and right sides of the placement box 402 form a guiding engagement with the guide block 405, and the left and right sides of the rear end of the placement box 402 respectively form a guiding engagement with the positioning block 404. The placement box 402 is designed with a locking mechanism. Elastic locking strips 403 are fixedly connected to both the front and rear ends of its left and right sides. The elastic locking strip 403 at the front end of the placement box 402 engages with the slots on the guide block 405, while the elastic locking strip 403 at the rear end engages with the slots on the positioning block 404. This means that after the placement box 402 is slid into place, the elastic locking strips 403 engage with the corresponding slots, ensuring reliable fixation of the placement box 402. In practical implementation, when a liquor sample needs to be poured into the placement box 402, the box can be pulled forward, causing the elastic locking strips 403 to deform elastically and disengage from their slots. The placement box 402 can then be pulled outwards before the liquor sample is poured in. After pouring, the placement box 402 is slid back inwards to reset its position. After the placement box 402 is slid into place, it is generally located in the center of the mesh plate 401. At least some holes on the mesh plate 401 are not blocked by the placement box 402 to facilitate the flow of hot air.

[0027] In a preferred embodiment of this utility model, the overall working principle is as follows: The liquor sample is poured into the placement box 402, which is then placed between the two guide blocks 405 and the two positioning blocks 404. The elastic locking strip 403 is engaged in the corresponding slots of the guide blocks 405 and the positioning blocks 404 to fix the placement box 402, ensuring that it is located at the center of the mesh plate 401. The sealing door 103 is then closed. According to usage requirements, a hexagonal wrench is inserted into the hexagonal slot (i.e., the rotating tool connector 206), causing the worm gear 204 to rotate. The worm gear 204 and worm wheel 205 work together to drive the lead screw 203 to rotate. This, in turn, causes the stroke control switch 202 of the first control mechanism 2 to move along the vertical slide groove 303, positioning it at the lowest air pressure value inside the drying chamber 101. Similarly, the second control mechanism 5 is adjusted so that its stroke control switch 202 is positioned at the highest air pressure value inside the drying chamber 101. The negative pressure device 102 then operates, extracting air from inside the drying chamber 101. The air pressure inside the drying chamber 101 is reduced, and the heating device inside the drying chamber 101 is activated to heat the chamber. Steam generated during the drying process is discharged through the negative pressure device 102. As the air pressure inside the drying chamber 101 decreases, the air pressure on the sealing piston 304 increases, pushing the sealing piston 304 downwards. This causes the slider 306 to contact the stroke control switch 202 of the first control mechanism 2. The stroke control switch 202 sends a sensing signal to the controller, reducing the power of the negative pressure device 102 and decreasing the suction speed of the negative pressure device 102 until the air pressure inside the drying chamber decreases. When the internal air pressure of the drying chamber 101 increases, the pressure spring 308 pushes the sealing piston 304 upward and separates it from the stroke control switch 202 of the first control mechanism 2. When the internal air pressure of the drying chamber 101 is too high, the pressure spring 308 pushes the sealing piston 304 upward, causing the slider 306 to contact the stroke control switch 202 of the second control mechanism 5. The controller controls the negative pressure device 102 to increase its power and speed up the air extraction of the negative pressure device 102, thereby reducing the internal air pressure of the drying chamber 101 and drying the air within a suitable range.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
