Description

Technical Field

[0001] The invention relates to the technical field of traditional Chinese medicine production equipment, in particular to an integrated traditional Chinese medicine decocting stove. Background Art

[0002] In the production of traditional Chinese medicine, a set amount of Chinese herbal medicine slices and water are stored in a decoction pot and decocted through a decoction unit. After decoction, the inner pot of the decoction pot is lifted so that the Chinese medicine liquid is stored in an outer pot. The Chinese medicine liquid in the outer pot is packaged by a packaging unit, and the medicine residue in the inner pot is poured out by a residue-discharging and pot-brushing unit. Then, the inner and outer pots are cleaned and reused by a cleaning unit. The existing Chinese medicine production line installs the decoction unit, cleaning unit, residue-discharging and pot-brushing unit and packaging unit independently on the ground, and then connects and transports them through an assembly line. During installation, each unit needs to be leveled, and then the equal height positions between the units are adjusted to meet the requirements, which makes it inconvenient to install the equipment; in addition, the distance back to the decoction pot is far; for this reason, the decoction unit, cleaning unit, residue-discharging and pot-brushing unit and packaging unit are concentrated on the chassis in a ring layout. However, the existing decoction unit is a single-layer layout stove, resulting in a low decoction capacity of the chassis. Summary of the Invention

[0003] The present invention aims to provide an integrated Chinese medicine decoction stove with a large decoction capacity while occupying a small plane space, thereby solving the problem of low decoction capacity of the existing decoction unit.

[0004] The specific technical solution of the present invention is: an integrated Chinese medicine decoction stove, including a stand, the stand having several layers of stoves distributed from top to bottom, the stoves being used to heat a decoction pot, a smoke exhaust duct being provided on the stand, an air inlet hood being provided above the stove, the air inlet hood being connected to the smoke exhaust duct, a temperature sensor being provided on the stand for one-to-one measurement of the temperature of the decoction pot located on the stove, and several connecting seats being provided below the stand. The modular integration of multiple stoves is achieved, facilitating the installation of multiple cover platforms on a chassis integrating multiple Chinese medicine decoction units. The gas generated during decoction can be conveniently discharged and the stability of the decoction pot can be checked to see if it meets the requirements.

[0005] Preferably, the connecting base is connected to the stand via stand fixing bolts; the connecting base is provided with anchor bolt holes for receiving the connecting base fixing bolts that secure the connecting base to the chassis; the stand is provided with a plurality of height-adjustable support legs, each of which is positioned above the connecting base in a corresponding manner. When storing and transporting the present invention, the support legs are used for support, the connecting base is removed, and the height of the support legs is adjusted to facilitate insertion of a forklift into the bottom of the stand to lift the present invention. When connected to the chassis, the support legs do not provide support, and connection is maintained via the connecting base.

[0006] Preferably, a plurality of connecting plates are provided on the lower end surface of the stand, and the connecting plates are positioned one-to-one above the connecting base. The connecting plates are provided with connecting plate bolt holes, and the stand fixing bolts are passed through the connecting plate bolt holes and then threadedly connected to the connecting base to fix the connecting base and the stand together. This facilitates operation when connecting the connecting base and the stand.

[0007] Preferably, the support leg comprises a vertical threaded rod and a support base connected below the threaded rod. The vertical threaded rod is threadedly connected to a support leg connecting plate, which is fixed to the stand via support leg connecting bolts. The connecting plate is located on the periphery of the stand and is exposed. When in use, the height of the support leg is adjusted by rotating the support leg.

[0008] Preferably, the lower end of the vertical threaded rod is provided with a regular hexagonal prism section. When in use, the support foot can be rotated by clamping a wrench on the regular hexagonal prism section, which makes it convenient to rotate the support frame.

[0009] Preferably, the stove comprises a panel and a heat source arranged below the panel. When in use, the decoction pot is supported on the panel, the panel is fixed to the stand, the rear side of the panel is connected to the rear side of the air inlet hood via a rear baffle, the left side of the panel is connected to the left side of the air inlet hood via a left baffle, the rear side of the left baffle is connected to the left side of the rear baffle, the right side of the panel is connected to the right side of the air inlet hood via a right baffle, and the rear side of the right baffle is connected to the right side of the rear baffle. The air inlet hood, the panel, the rear baffle, the left baffle and the right baffle form a decoction pot heating box with an opening at the front. Gas generated during decoction is fully discharged.

[0010] Preferably, between upper and lower adjacent stoves, the air inlet cover of the stove at the lower side is connected to the bottom of the stove at the upper side, which results in a compact structure.

[0011] Preferably, the front surface of the stove is provided with heat dissipation holes, which can dissipate heat from components inside the stove, and heat dissipation is particularly important when the stove is an induction cooker.

[0012] Preferably, each cooking range has two cooking ranges, and the air inlet hood is provided with two exhaust holes located one-to-one directly above the two cooking ranges, and the exhaust holes are connected to the smoke exhaust duct through exhaust pipes. This allows for a compact layout when there are many cooking ranges, and each cooking range can be exhausted independently.

[0013] Preferably, the smoke exhaust duct includes a main smoke exhaust pipe and two vertical smoke exhaust branch pipes. The upper ends of the two vertical smoke exhaust branch pipes are connected to the lower end of the main smoke exhaust pipe. The smoke exhaust pipes for the two exhaust holes on the same air inlet hood are connected to the two vertical smoke exhaust branch pipes in a one-to-one correspondence. This facilitates the connection between the air inlet hood and the smoke exhaust duct using existing standard pipe fittings. A drain pipe is provided at the lower end of the vertical smoke exhaust branch pipe. The drain pipe is equipped with a drain valve.

[0014] Preferably, the temperature sensor is located at the rear side of the stove, and the medicine decocting pot is placed on the stove from the front side when in use. The temperature sensor is subjected to little force during detection and is not easily damaged, and the temperature sensor does not interfere with the decoction pot being moved up and down the stove.

[0015] Preferably, the temperature sensor comprises a sensor body and a sensor head connected to the sensor body. Two temperature sensors are provided, and when in use, the sensor heads of both temperature sensors are in contact with the medicine decoction pot. By simultaneously observing both temperature sensors, it is possible to determine whether the temperature is correct. This avoids misjudgments of stability due to sensor failure, as the probability of both temperature sensors failing simultaneously is very small.

[0016] Preferably, the two temperature sensors are distributed along the left and right directions. The sensors can be used to determine whether the position of the medicine decocting pot on the stove meets the requirements.

[0017] Preferably, the device further includes a damper closing structure, wherein the air inlet hood is provided with an exhaust hole, the exhaust hole being connected to the smoke exhaust duct via an exhaust pipe, the exhaust pipe being connected to the exhaust hole at one end being lower than the other end, so that smoke in the smoke exhaust duct flows from top to bottom. The exhaust hole is hingedly connected to a damper that opens toward the exhaust end of the exhaust hole and is used to close the exhaust hole. The damper closing structure is used to drive the damper to close the exhaust hole. The damper is only opened when the stove is in use, and the damper is opened by the negative pressure generated by exhaust from the smoke exhaust duct.

[0018] Preferably, the smoke exhaust duct is located at the rear side of the stand, the stove includes a panel and a heat source arranged below the panel, the panel is provided with heat transfer holes extending in the front and rear directions and distributed in the left and right directions, the front ends of the heat transfer holes are closed, the gate closing structure includes a cylinder body, a first piston slidably connected to the cylinder body, a driving handle connected to the gate plate, a cable connected to the rear side of the driving handle at one end, and a displacement transmission structure for transmitting the movement of the first piston to the cable, the first piston isolates a first cavity and a second cavity in the first cylinder body, the first cavity is a sealed cavity, the cylinder body closes all the open ends of the heat transfer holes, the first cavity is provided with connecting holes corresponding to the heat transfer holes, the heat transfer holes are filled with air with a pressure of one standard atmospheric pressure, the cable is in a tensioned state when the gate plate is in a closed state, the gate plate is in a closed state when the temperature in the heat transfer hole is below 60°C, and the cable is in a relaxed state when the temperature in the heat transfer hole is above 80°C and the gate plate is in a closed state. The decoction pot only begins to produce large amounts of gas when the temperature reaches above 80°C. It's appropriate to open the damper at this time to avoid premature exhaust, which would cause the decoction pot to dissipate heat prematurely and cause excessive heat loss. When commissioning the equipment, adjust the exhaust wind force so that the damper can open when the cable is relaxed, allowing the damper to open in a timely manner. When the stove stops heating, the gas temperature in the heat dissipation hole drops, and the first piston resets, driving the damper to close. The heat dissipation hole allows heat from the heat source to be transferred not only through conduction through the panel but also through radiation. Radiation heat transfer is faster than conduction heat transfer, thus shortening the initial heating time. However, if the heat dissipation hole is left open, ventilation will cause significant heat loss. To prevent this heat loss, it needs to be sealed. However, a rigid closure can easily damage the panel under high pressure at high temperatures. This technical solution not only solves the above problems but also eliminates the need for sensors and motors to control the damper, making gate control more economical.

[0019] Preferably, the displacement transmission structure includes a liquid storage tube with one end sealed and connected to the second cavity, the other end of the liquid storage tube is provided with a cylinder section, the cylinder section is provided with a second piston, the second piston and the first piston isolate a liquid storage chamber between the cylinder and the liquid storage tube, the liquid storage chamber is filled with liquid, and the side of the second piston away from the liquid storage chamber is connected to the other end of the cable. A specific technical solution for a displacement transmission structure is provided. Through liquid transmission, the problem of gas temperature volume change affecting the transmission accuracy can be avoided. It is equivalent to the existing cable sliding in a balanced manner for transmission, which is easier to layout when the transmission path is tortuous.

[0020] Compared with the existing technology, the beneficial effects of the present invention are: multi-layer layout, one unit can decoct multiple decoction pots at the same time, and the decoction capacity is large; the exhaust structure is designed, the gas generated during decoction has little impact on the air, and is environmentally friendly; it can detect the temperature of the decoction pot, and the temperature sensor is subjected to little force during detection and is not easily damaged.
