[0025] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1-3 shown, an embodiment of the present utility model provides a traditional Chinese medicine fine powder drying device, including a tank body 1, a discharge valve 103, a stirring assembly and a heating assembly; a drying cavity is provided inside the tank body 1, the top of the tank body 1 is sealed, and its top surface has a feed inlet, the bottom of the tank body 1 has a discharge outlet, the feed inlet, the drying cavity and the discharge outlet are connected in sequence, and the discharge valve 103 is installed at the discharge outlet of the tank body 1, and the stirring assembly is installed on the tank body 1 for stirring the traditional Chinese medicine fine powder in the drying cavity;

[0027] The tank body 1 has an inner layer, an outer layer and an insulation cavity 101 formed between the inner layer and the outer layer. A water inlet is provided at a position on the side wall of the tank body 1 close to its top surface, and the water inlet is connected to the insulation cavity 101. A water inlet pipe 105 is hermetically installed at the water inlet, and a water outlet communicating with the insulation cavity 101 is provided on the lower surface of the tank body 1. A drain pipe 106 is hermetically installed at the water outlet, and a valve for controlling its passage is installed on the drain pipe 106;

[0028] The heating assembly includes a spiral heating wire and a thermostat 3. The heating wire is arranged inside the insulation cavity 101, the thermostat 3 is installed on the outer wall of the tank body 1, and the heating wire is connected to the thermostat 3.

[0029] In this embodiment, when drying the traditional Chinese medicine fine powder, first inject hot water or warm water into the insulation cavity 101 of the tank body 1 through the water inlet pipe 105, and then turn on the thermostat to heat the water in the insulation cavity 101 by using the heating wire. As the water temperature in the insulation cavity 101 gradually rises, the temperature in the drying cavity gradually increases. Then pour the traditional Chinese medicine fine powder from the feed inlet of the tank body 1 into the drying cavity for drying, and at the same time turn on the stirring assembly to stir the traditional Chinese medicine fine powder in the drying cavity to improve the drying rate. After the traditional Chinese medicine fine powder is dried, open the discharge valve 103, and use a receiving bucket to catch the traditional Chinese medicine fine powder falling from the discharge outlet of the tank body 1.

[0030] In this way, the traditional Chinese medicine powder can be dried simply and quickly, the drying rate is increased, the drying time is saved, and a relatively large amount of fine traditional Chinese medicine powder can be dried at one time.

[0031] It should be noted that the function of the thermostat 3 is to compare the set temperature value with the actual temperature and output a control signal to adjust the heating power of the heating wire, so as to achieve automatic temperature control. This control can be achieved in a variety of ways, including but not limited to controlling the power on and off of the heating wire through electrical components such as contactors and relays, or directly controlling the heating power of the heating wire by adjusting the magnitude of voltage, current and resistance.

[0032] Optionally, in order to further increase the temperature inside the tank body 1 and improve the drying efficiency, heating films 102, heating plates and other common heating elements can be installed on the inner wall of the tank body 1.

[0033] As a preferred embodiment, as Figure 2 shown, the tank body 1 includes a cylindrical barrel body and a conical tube. The top of the barrel body is sealed, and its bottom has an opening. A cavity one is formed on the side wall of the barrel body around its axis. The large-diameter end of the conical tube faces the lower surface of the barrel body, and the large-diameter end of the conical tube is hermetically connected to the opening at the bottom of the barrel body. A cavity two is provided on the side wall of the conical tube around its axis. The cavity one and the cavity two are connected to form a heat preservation cavity 101. The spiral heating wire is spirally arranged in the heat preservation cavity 101. The small-diameter end at the bottom of the conical tube forms the discharge port of the tank body 1. A vertically arranged discharge pipe is hermetically installed at the discharge port, and the inlet end of the discharge valve 103 is flange-connected to the bottom opening of the discharge pipe.

[0034] Furthermore, as Figure 1 and Figure 2 shown, a feed hopper 104 is hermetically installed at the feed port at the top of the tank body 1. The feed hopper 104 is funnel-shaped, and its top is screwed with a sealing cover. In order to prevent the traditional Chinese medicine powder from diffusing to the outside when stirring the traditional Chinese medicine powder, a sealing cover is screwed and installed on the feed hopper 104.

[0035] Preferably, a controller is further included in this embodiment. At least one first temperature sensor is installed in the heat preservation cavity 101, and at least one second temperature sensor is installed in the drying cavity. The first temperature sensor and the second temperature sensor are respectively connected to the controller in a signal manner. It should be noted that the first temperature sensor is used to measure the water temperature inside the heat preservation cavity 101, and the second temperature sensor is used to measure the temperature inside the drying cavity. The controller is connected to the temperature controller 3 in a signal manner. The controller compares the set temperature value with the actual water temperature (the temperature value output by the first temperature sensor), and outputs a control signal according to the comparison result. The relay adjusts the heating power of the heating wire according to the control signal, so as to realize the automatic control of the water temperature. Further, the second temperature sensor transmits the temperature inside the drying cavity to the controller in real time, and the controller controls the relay to increase the heating power of the heating wire according to the temperature value inside the drying cavity.

[0036] It should be noted that valves are installed on both the drain pipe 106 and the water inlet pipe 105. When draining water, only the valve on the drain pipe 106 needs to be opened.

[0037] In this embodiment, the stirring assembly includes a first stirring mechanism, a motor 5 and a stirring paddle. The stirring paddle includes a stirring shaft 4 and spiral blades arranged on the side surface of the stirring shaft 4. The stirring paddle is vertically and rotatably installed in the tank body 1. The motor 5 is installed on the top surface of the tank body 1, and the output end of the motor 5 is connected to the top end of the stirring paddle.

[0038] Considering that the fine traditional Chinese medicine powder in the middle of the tank body 1 accumulates together and is far from the inner wall of the tank body 1, and the temperature at the inner wall of the tank body 1 is relatively high, the drying rate of the fine traditional Chinese medicine powder in the middle of the tank body 1 will be slower.

[0039] To solve this problem, preferably, as Figure 3 shown, the stirring assembly further includes a second stirring mechanism. The second stirring mechanism includes a gear ring 7, a driving gear 8, at least one driven gear 9 and a turning shaft 6 corresponding to the driven gear 9 one by one; wherein, a fixing plate 107 is installed on the inner wall of the drying cavity near its top. The driving gear 8 is coaxially fixed on the stirring paddle and is higher than the fixing plate 107. The gear ring 7 is rotatably installed on the upper surface of the fixing plate 107, and the gear ring 7 is coaxially arranged with the driving gear 8. The driven gear 9 is engaged between the gear ring 7 and the driving gear 8. The top end of the turning shaft 6 is fixed to the corresponding driven gear 9. A plurality of disturbing blades 601 are arranged around the axis of the turning shaft 6. Further, multiple groups of disturbing blades 601 are provided. The multiple groups of disturbing blades 601 are arranged in sequence along the length direction of the stirring shaft 4. Each group of disturbing blades 601 includes at least two disturbing blades 601, and the disturbing blades 601 in each group of disturbing blades 601 are evenly arranged around the axis of the turning shaft 6.

[0040] While the motor 5 drives the stirring shaft 4 to rotate for stirring, the stirring shaft 4 drives the driving gear 8 to rotate. Since the driven gear 9 is engaged between the toothed ring 7 and the driving gear 8, the driven gear 9 is driven to revolve around the axis of the stirring shaft 4 while rotating itself. In this way, the Chinese medicine fines near the center of the drying chamber can be dialed to the inner wall of the drying chamber, and at the same time, the relatively dry fines on the inner wall of the drying chamber can be dialed to the center of the drying chamber, that is, the position of the Chinese medicine fines in the drying chamber can be continuously changed, the drying efficiency is increased, and the drying effect is ensured.

[0041] It should be noted that the spiral blades on the stirring shaft 4 can be replaced with other forms of stirring blades, as long as they do not interfere with the disturbing blades 601 on the turning shaft 6.

[0042] Preferably, as Figure 1 , the tank body 1 is placed on the support frame 2, and the support frame 2 is a stainless steel support frame, which can stably support the tank body 1.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. In addition, the terms "first", "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0044] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the connection inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. In addition, in the description of the present invention, unless otherwise stated, the meaning of "a plurality" is two or more.

[0045] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
