Description

Technical Field

[0001] The utility model belongs to a mixing and drying device, in particular to a temperature-controlled mixing and drying device for activated carbon molding. Background Art

[0002] Activated carbon is a black, porous solid carbon. It's a specially treated charcoal made by heating organic raw materials (such as fruit shells, coal, and wood) in an airless environment to reduce non-carbon components (a process called carbonization). Activated carbon then reacts with gases, eroding the surface and creating a well-developed microporous structure.

[0003] When activated carbon is formed during production, it is moist as a whole and needs to be dried before it can be used and stored.

[0004] Among them, when drying activated carbon, the existing method is to directly use a heating pump to transport hot air into the drying drum, which is energy-consuming to a certain extent. Utility Model Content

[0005] The utility model provides a temperature-controlled mixed drying device for activated carbon molding, which is used to solve the defects in the prior art.

[0006] The utility model is achieved through the following technical solutions:

[0007] A temperature-controlled mixed drying device for activated carbon molding includes a drying cylinder and an air inlet pipe. The air inlet end of the air inlet pipe is connected to a fan, and the air outlet end of the fan is connected to a first insulation box. The first insulation box is connected to the air inlet end of a second insulation box through several parallel solar heating tubes. The air outlet end of the second insulation box is connected to one end of the air outlet pipe, and the other end of the air outlet pipe is connected to the air inlet end of a heating pump. The air outlet end of the heating pump is connected to the air inlet end of the drying cylinder.

[0008] When the present application is in use, the gas is transported to the first insulation box by the fan and then enters each solar heating tube through the first insulation box and enters the second insulation box after being heated in the solar heating tube. After being mixed in the second insulation box, it enters the heating pump and is heated again. The heated hot gas enters the drying drum. Since the gas has been heated by the solar insulation tube before entering the heating pump, the heating pump needs very little capacity to heat it to the required temperature, thereby saving the energy consumed by the heating pump to a certain extent and achieving energy saving.

[0009] Preferably, the outlet pipe is connected to the air inlet end of a tee pipe, the air outlet end of the tee pipe is respectively connected to a branch air pipe and a connecting pipe, the connecting pipe is connected to the air inlet end of the heat pump, the branch air pipe and the air outlet end of the heat pump are both connected to a third insulation box, the air outlet end of the third insulation box is connected to one end of a round pipe, the other end of the round pipe is connected to the air inlet end of the drying drum, and a first solenoid valve and a second solenoid valve are respectively provided on the branch air pipe and the connecting pipe. The outlet pipe is connected to the tee pipe, and the first solenoid valve is opened and the second solenoid valve is closed by the tee pipe, so that in the hot summer, the gas that meets the temperature requirement after being heated by the solar heating tube enters the branch air pipe through the tee pipe and directly enters the drying drum without further heating, eliminating the need for heating by the heat pump and further saving energy. At the same time, when the heat pump needs to be reheated, the first solenoid valve can be closed and the second solenoid valve can be opened, allowing the gas to enter the heat pump for reheating.

[0010] Preferably, the outlet pipe and the circular tube are provided with a first thermometer and a second thermometer, respectively, so as to measure the temperature of the gas in the outlet pipe and the circular tube, thereby determining whether to open the first solenoid valve or the second solenoid valve, or the degree to which the first solenoid valve or the second solenoid valve is opened, to meet temperature control requirements.

[0011] Preferably, the solar heating tubes are arranged diagonally along the first insulation box, and a curved reflector with a convex rear portion is provided between the first and second insulation boxes. The reflector is located behind the solar heating tubes and faces the sun. The diagonal arrangement of the solar heating tubes along the first insulation box prevents obstruction between the upper and lower solar heating tubes, ensuring better heating of the solar heating tubes. The reflector also heats the back of the solar heating tubes, achieving better heating of the solar heating tubes.

[0012] Preferably, a filter box is provided between the fan and the first heat preservation box, with the fan outlet connected to the filter box inlet, which in turn is connected to the first heat preservation box inlet via a hose. A filter screen is inserted into the filter box. The filter screen can filter the air drawn in by the fan, preventing dust in the air from entering the solar heating tubes, thereby reducing dust obstruction to the solar heating tubes. It can also prevent the air from entering the drying drum, ensuring the purity of the activated carbon.

[0013] Preferably, the first and second insulated boxes are both fixedly mounted on a rotating plate, the bottom surface of which is perpendicularly connected to the rotating shaft of a fixed motor. Universal wheels are provided at the four corners of the bottom surface of the rotating plate. The universal wheels ensure rotation of the rotating plate while supporting the turntable, and the motor drives the rotating plate, ensuring that the solar heating tubes always face the sun, achieving optimal heating. The flexible hose and the air outlet pipe ensure that the rotation of the first and second insulated boxes does not affect their normal ventilation.

[0014] The beneficial effects of the present invention are as follows: The gas entering the drying drum is heated by the solar heat preservation tube before entering the heating pump, so the heating pump requires very little energy to heat the gas to the desired temperature, thereby saving energy consumption by the heating pump to a certain extent. Furthermore, the temperature of the gas entering the drying drum can be controlled by using the first and second solenoid valves and the first and second thermometers.

[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0021] A temperature-controlled mixed drying device for activated carbon molding, such as Figure 1 and Figure 2As shown. It includes a drying drum 1 and an air inlet pipe 2. The air inlet end of the air inlet pipe 2 is connected to a fan 3. The air outlet end of the fan 3 is connected to a first insulation box 4 through an air inlet hose. The first insulation box 4 is connected to the air inlet end of a second insulation box 6 through several parallel solar heating tubes 5. The air outlet end of the second insulation box 6 is connected to the air inlet end of an air outlet pipe. The air outlet pipe is a hose. The air outlet end of the air outlet pipe is connected to the air inlet end of a tee pipe 7. The air outlet end of the tee pipe 7 is respectively connected to a branch air pipe and a connecting pipe. The connecting pipe is connected to the air inlet end of a heating pump 16. The branch air pipe and the air outlet end of the heating pump 16 are both connected to a third insulation box 10. The air outlet end of the third insulation box 10 is connected to one end of a circular pipe. The other end of the circular pipe is connected to the air inlet end of the drying drum 1. A first solenoid valve 8 and a second solenoid valve 9 are respectively provided on the branch air pipe and the connecting pipe. The air outlet end of the heating pump 16 is connected to the air inlet end of the drying drum 1.

[0022] A first thermometer 11 and a second thermometer 12 are respectively provided on the air outlet pipe and the circular pipe.

[0023] When the present application is in use, the gas is transported to the first insulation box 4 through the fan 3 and then enters each solar heating tube 5 through the first insulation box 4 and enters the second insulation box 6 after being heated in the solar heating tube 5. After being mixed in the second insulation box 6, it enters the exhaust pipe and the temperature is measured by the first thermometer 11. When the temperature meets the requirements, the first solenoid valve 8 is opened and the second solenoid valve 9 is closed, so that the gas enters the branch air pipe through the three-way pipe 7, enters the third insulation box 10 through the branch air pipe, and enters the drying cylinder 1 from the third insulation box 10 through the circular pipe. The gas in the circular pipe is measured again. If it meets the temperature requirements, it is taken in. If it does not meet the temperature requirements and the difference is small, , then as needed, the first solenoid valve 8 and the second solenoid valve 9 are both opened, so that part of the hot gas is heated by the heat pump 16 and then mixed with the remaining gas in the third insulation box 10 and enters the round tube. If the gas temperature is significantly different from the required temperature, the first solenoid valve 8 is closed and the second solenoid valve 9 is opened, so that the gas heated by the solar heating tube 5 is heated again by the heat pump 16, and the heated hot gas enters the drying drum 1. Since the gas has been heated by the solar insulation tube before entering the heat pump 16, the heat pump 16 only needs a small amount of capacity to heat it to the required temperature, thereby saving the energy consumed by the heat pump 16 to a certain extent, thereby achieving energy conservation.

[0024] The air outlet pipe is connected to a three-way pipe 7, and through the three-way pipe 7, the first solenoid valve 8 is opened, and the second solenoid valve 9 is closed. This can ensure that when the temperature is high in summer, the gas that meets the temperature requirements after being heated by the solar heating tube 5 enters the branch air pipe through the three-way pipe 7 and directly enters the drying drum 1 through the branch air pipe without further heating, eliminating the need for heating by the heating pump 16, thereby further saving energy. At the same time, when the heating pump 16 needs to be reheated, the first solenoid valve 8 can be closed and the second solenoid valve 9 can be opened, so that the gas enters the heating pump 16 for reheating.

[0025] The first thermometer 11 and the second thermometer 12 can measure the temperature of the gas in the outlet pipe and the gas in the circular tube, so as to determine whether to open the first solenoid valve 8, the second solenoid valve 9 or the degree of opening of the first solenoid valve 8, the second solenoid valve 9 according to needs to meet temperature control.

[0026] The solar heating tubes 5 are arranged diagonally and tilted along the first insulated box 4. A curved reflector 14, convex from the rear of the boxes, is located between the first and second insulated boxes 4, 6. Mirror 14 is located behind the solar heating tubes 5 and faces the sun. This diagonal tilt of the solar heating tubes 5 along the first insulated box 4 prevents obstruction between the upper and lower solar heating tubes 5, ensuring better heating. The reflector 14 also heats the back of the solar heating tubes 5, achieving even better heating.

[0027] The first and second insulation boxes 4 and 6 are both fixedly mounted on a rotating plate 13. The bottom surface of the rotating plate 13 is perpendicularly connected to the rotating shaft of the fixed motor. Universal wheels are provided at the four corners of the bottom surface of the rotating plate 13. The universal wheels ensure the rotation of the rotating plate 13 while supporting the turntable. The motor drives the rotating plate 13 to rotate, ensuring that the solar heating tubes 5 always face the sun, achieving better heating.

[0028] A filter box 15 is provided between the fan 3 and the first heat-insulating box 4. The air outlet of the fan 3 is connected to the air inlet of the filter box 15, which is in turn connected to the air inlet of the first heat-insulating box 4. A filter screen is inserted into the filter box 15. The filter screen filters the air drawn in by the fan 3, preventing dust in the air from entering the solar heating tubes 5, thereby reducing dust obstruction to the solar heating tubes 5. It also prevents the air from entering the drying drum 1, ensuring the purity of the activated carbon.

[0029] In the present application, since the gas before entering the heat pump 16 has already been heated by the solar heat preservation tube, the heat pump 16 requires very little power to heat the gas to the desired temperature, thereby saving energy consumption by the heat pump 16 to a certain extent, thereby achieving energy conservation. At the same time, the first solenoid valve 8, the second solenoid valve 9 and the first thermometer 11 and the second thermometer 12 can be used to control the temperature of the gas entering the drying drum 1.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
