[0033] The core of the present application is to provide a material conveying device which has the conveying function and the cooling function while the land occupation area is reduced.

[0034] In order to make those skilled in the art better understand the technical scheme of the present application, the present application will be further described in detail in combination with the drawings and embodiments.

[0035] Please refer to Figures 1 to 4 .

[0036] In a specific embodiment, the material conveying device provided by the specific embodiment of the utility model includes a barrel 12 and a cooling assembly. The barrel 12 and the cooling assembly can be processed from a metal material. In order to prolong the service life of the barrel 12 and the cooling assembly, preferably, the inner wall of the barrel 12 is provided with a high-temperature-resistant anticorrosive layer. The high-temperature-resistant anticorrosive layer can adopt a Teflon coating layer which is corrosion-resistant, high-temperature-resistant and wear-resistant, so that the material can be prevented from directly contacting the barrel 12. Alternatively, all surfaces in contact with the material in the material conveying device are provided with a high-temperature-resistant anticorrosive layer.

[0037] The barrel 12 is a vertical barrel 12. The top end of the barrel 12 is provided with a feeding port 1, and the bottom end of the barrel 12 is provided with a discharging port 9. In order to facilitate the smooth sliding of the material, preferably, the barrel 12 is a cylinder, and the inner wall of the barrel 12 is smoothly transitioned at the corner position. For example, the top surface and the vertical surface of the barrel 12 are smoothly transitioned, and the bottom surface and the vertical surface of the barrel 12 are smoothly transitioned.

[0038] In order to facilitate the control of the flow of the material, preferably, the feeding port 1 and the discharging port 9 are respectively provided with control valves. Specifically, the control valve can be an electromagnetic valve or a manual valve, for example, the control valve is a butterfly valve.

[0039] The cooling assembly includes a jacket which is sleeved on the outer periphery of the barrel 12. The inner wall of the jacket and the outer wall of the barrel 12 form a cooling liquid flowing space 4. The jacket is provided with a liquid inlet 7 and a liquid outlet 8. The cooling liquid flowing space 4 is filled with cooling liquid. Preferably, the vertical surface of the jacket can also be cylindrical, and the distance between the vertical surface of the jacket and the vertical surface of the barrel 12 is equal. The inner wall of the jacket is provided with a high-temperature-resistant anticorrosive layer. The high-temperature-resistant anticorrosive layer can adopt a Teflon coating layer which is corrosion-resistant, high-temperature-resistant and wear-resistant, so that the cooling liquid can be prevented from directly contacting the inner wall of the jacket.

[0040] When the material needs to be conveyed, the material enters the barrel 12 through the feeding port 1. The material entering the barrel 12 is discharged through the discharging port 9. The cooling liquid flows in the cooling liquid flowing space 4 to cool the material in the barrel 12.

[0041] As known from the above description, in the material conveying device provided by the specific embodiment of the present application, the barrel 12 is a vertical barrel 12. The jacket is directly sleeved on the outer periphery of the barrel 12, and forms the cooling liquid flowing space 4 in combination with the outer wall of the barrel 12. No additional cooling structure is needed, the material can be cooled at the same time, the waste of cost is reduced, the material conveying device occupies less area, and the material conveying device has both conveying function and cooling function.

[0042] On the other hand, the barrel 12 is a vertical barrel, which can solve the problem of large occupied space and also make the material better transmitted by gravity.

[0043] In one specific embodiment, the liquid inlet 7 and the liquid outlet 8 are located on opposite sides of the jacket. Specifically, the center of the barrel 12 is located on the center line of the liquid inlet 7 and the liquid outlet 8. Since the feed inlet 1 is located at the top end of the barrel 12, the temperature at the top end of the barrel 12 is relatively high. In order to cool the material in time, preferably, the liquid inlet 7 is higher than the liquid outlet 8.

[0044] Since the internal environment control of the conventional material conveying is poor, such as conveying high-temperature materials, the water vapor generated during the conveying process of the materials is not easy to volatilize, and the water vapor will condense into water droplets on the inner wall of the conveyor, thereby causing the moisture content of the materials to exceed the standard and the materials to deteriorate. The material conveying device provided in the present application further comprises a gas conveying pipe 5 and a gas outlet pipe, the gas outlet pipe is provided with a one-way exhaust valve 6 or an exhaust fan, the gas outlet pipe is connected to the barrel 12 and is used for exhausting the barrel 12.

[0045] The gas conveying pipe 5 is connected to the barrel 12 and is used for conveying dry gas to the barrel 12. Specifically, the dry air can be dry N2 or dry compressed air, which can also achieve the effect of protective gas, ensuring the dryness and cleanliness of the internal environment of the barrel. A chamber for compressed air can also be provided on the exhaust pipe, and a control valve is provided on the exhaust pipe. When the material conveying device conveys materials, the control valve is opened, and the compressed air enters the barrel 12.

[0046] Specifically, the gas outlet pipe is provided with a one-way exhaust valve 6, which is preferably a filter valve body to prevent materials from being discharged from the gas outlet pipe.

[0047] In order to facilitate the exhaust of the barrel 12, preferably, an exhaust fan is arranged on the gas outlet pipe.

[0048] The one-way exhaust valve 6 or the exhaust fan provided in the present application can carry away the water vapor volatilized during the cooling of the materials, forming a protective atmosphere in the material conveying device, and avoiding the deterioration of the materials during the conveying process. That is, the materials will not deteriorate during the conveying process to the next stage of equipment, and finally achieve the multiple effects of conveying, cooling and protection.

[0049] In one specific embodiment, the gas conveying pipe 5 and the gas outlet pipe are arranged at the top of the barrel 12 and are located at opposite ends of the top of the barrel 12. Specifically, the gas conveying pipe 5 and the gas outlet pipe are arranged on the left and right sides of the top of the barrel 12. By arranging the gas conveying pipe 5 and the gas outlet pipe, the gas pressure in the barrel 12 is balanced, and the gas is dry nitrogen or dry compressed air, which avoids reacting with the materials or humidifying the materials.

[0050] In another specific embodiment, the gas conveying pipe 5 is arranged at the top end of the barrel 12, the gas outlet pipe is arranged at the bottom of the barrel 12, and the gas conveying pipe 5 and the gas outlet pipe are diagonally arranged on the barrel 12, for example, the gas conveying pipe 5 is arranged at the upper left of the barrel 12, and the gas outlet pipe is arranged at the lower right of the barrel 12.

[0051] The gas enters the barrel 12 through the gas delivery pipe 5 and the gas outlet pipe at a certain distance, which facilitates the disturbance of the material and the removal of the water vapor generated during the cooling of the material, thereby ensuring the cleanliness of the internal environment of the barrel 12.

[0052] In a specific embodiment, the material conveying device further comprises a spiral conveying paddle 2 and a motor 3, the spiral conveying paddle 2 is arranged in the barrel 12, and the inlet 1 and the outlet 9 are diagonally arranged on the opposite sides of the axial direction of the spiral conveying paddle 2. Specifically, the rotation axis of the spiral conveying paddle 2 coincides with the center line of the vertical direction of the barrel 12.

[0053] The motor 3 is installed on the outer wall of the barrel 12 and connected with the spiral conveying paddle 2 to drive the rotation of the spiral conveying paddle 2. Specifically, the motor 3 is a spiral motor 3 for driving the rotation of the spiral conveying paddle 2, which can effectively promote the transmission of the material in the barrel 12. Under the dual action of the spiral conveying paddle 2 and the gravity of the material, the material transmission is more smooth.

[0054] On the basis of the above-mentioned schemes, the cooling assembly further comprises a liquid delivery pipe, a pump body 10 and a cooler 11. Specifically, the pump body 10 can be a peristaltic pump, and the opposite ends of the liquid delivery pipe are connected with the liquid inlet 7 and the liquid outlet 8, respectively. Specifically, the liquid delivery pipe can be installed on the outer wall of the jacket, and the pump body 10 is arranged in the liquid delivery pipe. The cooler 11 is arranged in the liquid delivery pipe to cool the cooling liquid. The cooling water in the cooling liquid flow space 4 is connected with the cooling water inlet 7 and the cooling water outlet 8 through the liquid delivery pipe, and the cooling water is kept in a flowing state under the action of the pump body 10, effectively removing the heat radiated by the material through the cooler 11 to achieve the cooling effect.

[0055] In order to facilitate understanding, the following will be described in combination with two specific working modes:

[0056] As shown in Figure 2 For the case of conveying normal temperature material: the ordinary material enters the barrel 12 through the butterfly valve of the inlet 1, the motor 3 drives the spiral conveying paddle 2 to convey the material from top to bottom to the butterfly valve of the outlet 9, and then outputs, the material enters the next stage equipment, at the same time, the exhaust action of the one-way exhaust valve 6 balances the pressure inside and outside the material conveying device and also ensures the cleanliness of the internal environment. During the material conveying process, the pump body 10 is in the off state, and the cooling liquid in the cooling liquid flow space 4 is in a static state, and does not play its cooling function.

[0057] As shown in Figure 3As shown, for the case of high-temperature material conveying: the high-temperature material (dried material) enters the barrel 12 through the butterfly valve of the feed port 1, the motor 3 works to drive the spiral conveying blade 2 to convey the material from top to bottom to the butterfly valve of the discharge port 9, and then output, and the material enters the next stage equipment. During the material conveying process, the pump body 10 is in working state, the cooling liquid in the cooling liquid flow space 4 flows from the water outlet, passes through the cooler 11 after cooling, and then reenters the cooling liquid flow space 4 through the water inlet, so as to circulate back and forth, better taking away the heat radiated by the high-temperature material, and achieving the effect of cooling the material. At the same time, the gas conveying pipe 5 continuously conveys dry N2 into the inside of the barrel 12, and the water vapor volatilized during the cooling of the material can be taken away through the exhaust function of the one-way exhaust valve 6, so as to ensure the cleanliness of the inside of the barrel 12 and avoid the deterioration of the material during the conveying process.

[0058] The application adopts the spiral conveying principle and the vertical barrel 12, increases the cooling assembly, and the barrel 12 can be protected by dry N2, and the material is conveyed to the next stage equipment under the action of gravity and spiral pushing. In the process of spiral pushing of the material, the water in the cooling liquid circulates and flows, takes away the heat radiated by the material, and achieves the purpose of cooling. The application is equipped with circulating water cooling and protective gas on the basis of the traditional conveying function, realizes the multiple effects of conveying, cooling and protection, and is convenient for wide promotion.

[0059] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments, and the same and similar parts between the various embodiments can be referred to each other.

[0060] The above description of the disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
