Description

Technical Field

[0001] The utility model relates to the technical field of rotary discharge valves, in particular to a cooling structure of a rotary discharge valve. Background Art

[0002] With the continuous advancement of industrial production technology, the demand for handling high-temperature materials is increasing. Due to its unique structure and working principle, the rotary discharge valve is widely used in the conveying and unloading process of high-temperature solid materials. However, the rotary discharge valve will face significant heat dissipation problems in the process of handling high-temperature materials for a long time. In particular, the temperature of key components such as rotating shafts, sealing packings and rolling bearings will rise rapidly when working under high temperature conditions, which will not only affect the normal operation of the rotary discharge valve, but also may cause damage to the equipment, shorten its service life, and increase maintenance costs.

[0003] Traditional rotary discharge valve designs usually ignore the effective cooling of these components, or the heat dissipation measures adopted cannot meet the heat dissipation requirements under actual working conditions. For example, some rotary discharge valves rely only on natural heat dissipation or use air cooling. These methods may be sufficient when handling low-temperature materials, but in high-temperature environments, their heat dissipation efficiency is far from sufficient and cannot effectively reduce the operating temperature of key components. This not only limits the ability of the rotary discharge valve to handle high-temperature materials, but also seriously affects the stability and safety of the equipment.

[0004] Therefore, there is an urgent need for an improved cooling structure that can effectively solve the heat dissipation problem encountered by the existing rotary discharge valve when processing high-temperature solid materials, so as to improve the cooling efficiency of key components such as the rotating shaft, sealing packing and rolling bearing, thereby improving the stability, safety and service life of the equipment. In this regard, a "cooling structure for a rotary discharge valve" is proposed, aiming to efficiently solve the above technical problems through water cooling and heat dissipation, and meet the demand for efficient and reliable rotary discharge valves in industrial production.

[0016] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0018] Reference Figure 1-2 A cooling structure of a rotary discharge valve comprises a discharge valve body 1, and both ends of the discharge valve body 1 are connected with fixed flanges 8, the surface of the fixed flanges 8 is connected with a sealing cavity tube 7, and both ends of the discharge valve body 1 are connected with heat-conducting rings 15, and the heat-conducting rings 15 are arranged inside the sealing cavity tube 7; a material inlet 3 and a material outlet 9 are respectively arranged on both sides of the surface of the discharge valve body 1, a driving motor 4 is installed on the rear side of the discharge valve body 1, and a transmission box 5 is arranged on the side of the discharge valve body 1, a rotating shaft 13 is rotatably connected to the inside of the discharge valve body 1 through a rolling bearing, and a sealing packing 14 is filled between the rotating shaft 13 and the sealing packing 14, a plurality of rotors are arranged on the outside of the rotating shaft 13, and the rotors are movably connected to the inside of the discharge valve body 1, and the driving motor 4 is installed on the rear side of the discharge valve body 1, and a transmission box 5 is arranged on the side of the discharge valve body 1, and a rotating shaft 13 is rotatably connected to the inside of the discharge valve body 1 through a rolling bearing, and a sealing packing 14 is filled between the rotating shaft 13 and the sealing packing 14, and a plurality of rotors are arranged on the outside of the rotating shaft 13, and the rotors are movably connected to the inside of the discharge valve body 1, and the driving motor 4 is installed on the rear side ... The motor 4 provides a driving source for the transmission box 5, so that the transmission box 5 drives the rotating shaft 13 to rotate, and then when the solid material is poured into the interior of the discharge valve body 1 through the material inlet 3, the driving motor 4 can drive the rotating shaft 13 and the rotor arranged outside the rotating shaft 13 to rotate through the transmission box 5, so that the solid material can be quickly discharged through the material discharge port 9; a cooling cavity is formed between the heat conductive ring 15 and the sealing cavity tube 7, and the heat conductive ring 15 can be a component made of graphene material; the outer sides of the two sealing cavity tubes 7 are respectively connected to the water injection pipe 2 and the water outlet pipe 6, and the outer sides of the two sealing cavity tubes 7 are commonly connected to a connecting water pipe 12, one end of the water injection pipe 2 and the water outlet pipe 6 are both arranged at the inner top of the cooling cavity, and the two ends of the connecting water pipe 12 are respectively arranged at the inner bottom of the two cooling cavities.

[0019] In one embodiment of the utility model, when the rotary discharge valve is used to discharge high-temperature materials, the end of the water injection pipe 2 away from the sealing cavity pipe 7 can be connected to the external cold water input pipe, and the end of the water outlet pipe 6 away from the sealing cavity pipe 7 can be connected to the external cooling water recovery pipe. Subsequently, cooling water is injected into the interior of the water injection pipe 2 through the external cold water input pipe, and the cooling water will flow inside the two cooling cavities and the connecting water pipe 12. As the cooling water continues to flow, the cooling water will absorb the heat of the heat-conducting ring 15 and the sealing packing 14. Since the sealing packing 14 is closely attached to the rotating shaft 13, the technical effect of quickly cooling the rotating shaft 13 can be achieved, and the flowing cooling water can also cool the sealing packing 14 and the rolling bearing, thereby improving the service life of the rotary discharge valve;

[0020] Through the above technical scheme, when the discharge valve body 1 discharges high-temperature materials, it can provide efficient water cooling and heat dissipation measures for the rotating shaft 13, the sealing packing 14 and the rolling bearing, thereby greatly improving the heat dissipation efficiency of the rotating shaft 13, the sealing packing 14 and the rolling bearing, and improving the service life of the rotary discharge valve.

[0021] Preferably, the ends of the water injection pipe 2 and the water outlet pipe 6 away from the sealing cavity tube 7 are both provided with flange connectors, so that the ends of the water injection pipe 2 and the water outlet pipe 6 away from the sealing cavity tube 7 can be conveniently fixedly connected to the external cold water input pipeline and the external cooling water recovery pipeline respectively.

[0023] In this embodiment, by setting up a temperature display 11 and a temperature sensor, the staff can monitor the temperature of the cooling water that has absorbed heat inside the connecting water pipe 12 in real time, and when the temperature of the cooling water is at a high state, the staff can understand that the flow rate of the cooling water inside the connecting water pipe 12, the water injection pipe 2 and the water outlet pipe 6 cannot meet the cooling demand of the rotary unloading valve. Therefore, the staff can appropriately increase the cold water delivery rate of the external cold water input pipe to speed up the heat exchange efficiency of the cooling water to the rotary unloading valve, so that the flow rate of the cooling water can meet the cooling demand of the rotary unloading valve.

[0024] Preferably, an electronic flow valve 10 is installed on the outside of the connecting water pipe 12, and the electronic flow valve 10 is electrically connected to the temperature display 11, so that under the premise that the cold water delivery rate of the external cold water input pipeline is at a high state, the electronic flow valve 10 can automatically adjust the flow rate of the cooling water inside the connecting water pipe 12, the water outlet pipe 6 and the water injection pipe 2 according to the actual temperature of the cooling water flowing inside the connecting water pipe 12, so as to improve the automation degree of the rotary unloading valve;

[0025] It can be understood that the temperature display 11 is preferably installed on the outside of the water outlet pipe 6 , and the electronic flow valve 10 is preferably installed on the outside of the water injection pipe 2 .
