Description

Technical Field

[0001] This technical solution relates to the field of filter washing and drying machine technology, specifically a dual-heating dryer. Background Technology

[0002] The "filtration, washing and drying machine" is a multi-functional integrated chemical equipment, mainly used in the pharmaceutical, chemical, food, pesticide, and dye industries. Its biggest feature is that it integrates the three key operations of filtration, washing and drying, which traditionally require multiple pieces of equipment (such as filters, washing tanks and dryers), into a single closed device for continuous completion. Therefore, it is also known as a "three-in-one device".

[0003] In operation, the filtration and washing process of a filter washing dryer requires stirring the mixture (suspension). During the stirring process, the mixture needs to be heated to accelerate the dissolution of the solute or increase its solubility. Existing dryers heat the mixture inside the tank by heating the tank body, which is inefficient and has poor heating effect. Summary of the Invention

[0004] The purpose of this technical solution is to provide a dual-heating dryer. By adding a heating mechanism to the washing tank, the heating mechanism injects a heat source into the channel opened in the stirring section, and the stirring section heats the dryer from the inside, thus solving the problem of low heating efficiency of the original equipment.

[0005] The purpose of this technical solution is achieved as follows:

[0006] A dual-heating dryer includes: a washing tank with an internal receiving chamber, the washing tank also having an inlet and an outlet; a stirring mechanism disposed on the washing tank and partially extending into the receiving chamber for stirring a mixture containing materials; a filtering mechanism disposed in the washing tank for filtering the mixture; and a heating mechanism disposed on the washing tank for heating the mixture or drying materials; wherein the stirring mechanism includes: a driving member; and a stirring section disposed at the output end of the driving member, the stirring section including a shaft and a plurality of blades disposed on the shaft, the shaft and all the blades having channels; when a heat source is injected into the channels, the stirring section can heat the mixture in the receiving chamber; the heating mechanism includes a first heating component and a second heating component, the first heating component including: a storage cylinder communicating with the channel for storing the heat source; and a pump body disposed on the channel for pumping the heat source.

[0007] Preferably, the inlet and outlet of the channel are both located at the upper end of the shaft; the heat source enters through the inlet, and after the channel is filled, the heat source circulates once in the channel and is discharged through the outlet.

[0008] Preferably, a heat source cavity is provided inside the blade, and the heat source cavity is connected to the channel.

[0009] Preferably, the washing tank has an outer shell and an inner liner, with an installation space formed between the outer shell and the inner liner; the second heating assembly is disposed within the installation space and includes a plurality of heaters, all of which are arrayed within the installation space.

[0010] Preferably, the second heating assembly includes a plurality of heaters, all of which are disposed on the outer wall of the washing tank.

[0011] Preferably, the washing tank includes an integrally formed cylindrical portion and a conical portion, with the discharge port located on the conical portion; the filtration mechanism includes: a filter screen disposed on the inner surface of the conical portion; at least one first filtrate port disposed on the conical portion; a second filtrate port disposed at the bottom of the conical portion; a filter cake portion disposed at the opening of the conical portion; and a ball valve disposed at the discharge port; wherein the first filtrate port and the second filtrate port are both connected to the receiving chamber.

[0012] Preferably, the flow rate of the first filtrate outlet is greater than that of the second filtrate outlet.

[0013] Preferably, the filter screen covers the first filtrate inlet, and the filter screen also covers the opening of the cone.

[0014] Preferably, the first filtrate outlet is located above the opening.

[0015] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0016] 1. The first heating component designed in this technical solution can be used in conjunction with a stirring section with a unique structure to heat the mixture from the inside. During the stirring process, the blades can fully contact the mixture, which greatly improves the heating efficiency. The storage tank and the channel in the stirring section are connected, and the heat source circulates in the storage tank and the channel, continuously heating the mixture through the stirring section. The pump body can ensure that the heat source fills the channel and can also ensure the circulation of the heat source. When the temperature of the heat source decreases, it can be heated in the storage tank to ensure the heating effect.

[0017] 2. The mixing section designed in this technical solution has two types of channels. One is that the inlet and outlet pipes are opened in the blades and the inlet and outlet pipes are connected to the channel of the shaft. This structure can ensure that after the heat source is injected, the heat source will gradually fill the channel and no air will remain in the channel, thus affecting the heating effect. The other is that a heat source cavity is opened in the blades. The heat source cavity has only one inlet connected to the channel. This structure can increase the volume of the channel that can accommodate the heat source and increase the contact area between the heat source and the blades, thereby improving the heating efficiency.

[0026] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0027]

Example 1

[0028] like Figure 1 As shown, a dual-heating dryer includes a washing tank 1, a stirring mechanism 5, a filtering mechanism 6, and a heating mechanism 7. The washing tank 1 includes a cylindrical part 17 and a conical part 18, which can be integrally formed or welded together. The cylindrical part 17 is located above the conical part 18. The washing tank 1 is hollow to form a receiving chamber 2. The washing tank 1 also has a feed inlet 3 and a discharge outlet 4. During processing, the material can be added into the washing tank 1 first, and then a solvent can be injected for mixing, or a mixture of materials can be added directly.

[0029] The stirring mechanism 5 is partially installed on the washing tank 1 and partially extends into the receiving chamber 2. The stirring mechanism 5 is used to stir the mixture containing materials so that the materials are fully dissolved or the mixture is stirred evenly. The filtration mechanism 6 is installed in the washing tank 1. The heating mechanism 7 includes a first heating component and a second heating component. The first heating component and the second heating component cooperate with each other to heat the mixture.

[0030] Specifically, such as Figure 2 and 3 As shown, the stirring mechanism 5 includes a driving component 8 and a stirring section 9. The driving component 8 can be a drive motor, and the stirring section 9 is located at the output end of the drive motor. The stirring section 9 includes a shaft 10 and several blades 11. In this embodiment, the blades 11 are cylindrical in shape and are formed on the periphery of the shaft 10. Both the shaft 10 and the blades 11 have channels 12 for the flow of heat source. The channels 12 have inlets and outlets. The heat source enters through the inlet, flows through each blade 11, and is discharged through the outlet. During this process, the blades 11 can be heated. Since the blades 11 are in direct contact with the mixture and continuously stir the mixture, the mixture can be effectively heated.

[0031] Furthermore, the first heating component includes a liquid storage cylinder and a pump body. The liquid storage cylinder is connected to the inlet and outlet of the channel 12, and the pump body is located at the inlet of the channel 12. In this embodiment, the heat source is hot oil or other liquids with fluidity.

[0032] like Figure 1 As shown, the washing tank 1 has an outer shell 14 and an inner liner 15, with an installation space formed between the outer shell 14 and the inner liner 15. A second heating assembly is disposed in the installation space. The second heating assembly includes a plurality of heaters 16, all of which are arrayed in the installation space. The heaters 16 are used to heat the mixture or dry the material. The heaters 16 are disposed in the installation space to ensure their cleanliness and increase the heat transfer efficiency.

[0033] [Modification] The second heating assembly includes several heaters 16, all of which are disposed on the outer wall of the washing tank 1.

[0034] like Figure 1 and Figure 7As shown, the washing tank 1 includes a cylindrical part 17 and a conical part 18. The discharge port 4 is opened on the conical part 18, which can collect and discharge waste liquid containing impurities. The filtration mechanism 6 includes a filter screen 19, a first filtrate port 20, a second filtrate port 21, a filter cake part 22, and a ball valve 23. The filter screen 19 is set on the inner surface of the conical part 18, and its shape is adapted to the shape of the conical part 18. The first filtrate port 20 is set on the conical part 18, and its number is set to at least one. It is used to quickly discharge waste liquid. The second filtrate port 21 is set at the bottom of the conical part 18. Both the first filtrate port 20 and the second filtrate port 21 are connected to the receiving chamber 2. The filter cake part 22 is set at the opening of the conical part 18 and is located above the second filtrate port 21. Since there is also sedimentation in the waste liquid, the second filtrate port 21 discharges the waste liquid filtered by the filter cake part 22. The filter cake part 22 can filter the mixture again to reduce material loss. The ball valve 23 is set at the discharge port 4.

[0035] Furthermore, the first filtrate port 20 is located above the opening, and the flow rate of the first filtrate port 20 is greater than that of the second filtrate port 21, or the sum of the flow rates of all the first filtrate ports 20 is greater than that of the second filtrate port 21. When discharging waste liquid, the first filtrate port 20 can be opened alone for rapid discharge, or the second filtrate port 21 can be opened alone to achieve discharge after secondary filtration.

[0036] Furthermore, the filter screen 19 covers the first filtrate inlet 20 and also covers the opening of the cone 18, which refers to the opening at the lower end of the cone 18. The filter screen 19 can also filter the material again, reducing material loss.

[0037]

Example 2

[0038] The setup in this embodiment is largely the same as that in Embodiment 1, the only difference being the structure of the channel 12 inside the blade 11, such as... Figure 4 As shown, in this embodiment, a cylindrical heat source cavity 13 is formed inside the blade 11. The inlet of the heat source cavity 13 is connected to the channel 12. When the heat source enters through the channel 12, it flows into the heat source cavity 13 to fully heat the blade 11. The heat source has a large contact area with the inner surface of the blade 11 inside the heat source cavity 13, which can improve the heating efficiency.

[0039]

Example 3

[0040] This embodiment is largely the same as embodiment 2, the only difference being the shape of the blade 11, such as... Figure 5 and 6 As shown, in this embodiment, the blade 11 is paddle-shaped, and the paddle-shaped blade 11 also has a heat source cavity 13, the shape of which is adapted to the shape of the blade 11.
