Description

Technical Field

[0001] The utility model relates to the technical field of steam overcurrent devices, and specifically relates to a high-temperature and normal-pressure steam overcurrent device. Background Art

[0002] Steam is a heat energy transfer medium and is widely used in chemical production, daily heating, and other aspects.

[0003] After retrieval, in the application with the patent application number CN201921852361.3, a steam reheating device is disclosed, including a housing, an external steam pipe, and a controller. It is characterized in that: several electric heating pipes with radiating fins are arranged in the housing. In front of the electric heating pipes, there is an air outlet pipe with steam holes and closed at both ends that communicates with the external steam pipe. On the housing at one end of the electric heating pipe, there is a terminal for controlling connection with the controller. An air outlet is arranged on the rear wall of the housing;

[0004] Although the steam reheating device reheats the steam by arranging electric heating pipes inside the housing, the heating pipes of the steam reheating device are not easy to disassemble. After long-term use, the heating pipes are prone to damage, and the whole device needs to be replaced, resulting in a relatively high maintenance cost.

[0005] Therefore, we propose a high-temperature and normal-pressure steam overcurrent device. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a high-temperature and normal-pressure steam overcurrent device, which solves the problems that the heating pipes of the existing device are not easy to disassemble, are prone to damage after long-term use, and the whole device needs to be replaced, resulting in a relatively high maintenance cost.

[0007] To achieve the above objectives, the utility model is realized through the following technical solutions: A high-temperature and normal-pressure steam overcurrent device includes an air inlet pipe, and a heating cover is fixedly installed at the bottom end of the air inlet pipe;

[0008] A heater is arranged inside the heating cover, and a gas distribution pipe is arranged at the bottom end of the heating cover;

[0009] An opening is arranged at the top end of the heating cover, an installation ring is fixedly installed on the top surface of the opening, an installation disk is fixedly installed on the top surface of the heater, threaded holes are opened on both the installation ring and the installation disk, a first bolt is threadedly sleeved inside the threaded hole, a flange disk is fixedly installed at the top end of the gas distribution pipe, the flange disk is installed on the bottom surface of the heating cover through a second bolt, and an exhaust pipe is arranged on the side wall of the gas distribution pipe.

[0010] Preferably, the exhaust pipe is fixedly installed on the side wall of the manifold and communicates with the manifold. The end of the exhaust pipe away from the manifold is connected to the steam-using device. The manifold is interconnected with the heating cover through a flange. Five exhaust pipes are evenly distributed. Among them, after the steam is heated by the heater and enters the interior of the manifold, the air pressure inside the manifold increases. The exhaust pipe can accelerate the discharge rate of the heated steam inside the manifold, avoiding the occurrence of potential safety hazards caused by excessive air pressure inside the manifold.

[0011] Preferably, a gasket is assembled between the top surface of the flange and the bottom surface of the heating cover. Through the gasket, the gap between the flange and the heating cover can be filled, increasing the sealing performance between the flange and the heating cover and avoiding steam leakage.

[0012] Preferably, a protective cover is fixedly installed at the top end of the heater. Through the protective cover, the heater can be protected, avoiding the situation that the top end of the heater overheats and scalds others, and at the same time reducing the heat dissipation of the steam inside the heating cover.

[0013] Preferably, a heat insulation cover is fixedly sleeved on the outer surface of the heating cover. Through the heat insulation cover, the steam inside the heating cover can be insulated, thereby slowing down the rate of temperature reduction of the steam inside the heating cover.

[0014] The utility model provides a high-temperature and normal-pressure steam overcurrent device, which has the following beneficial effects:

[0015] 1. For this high-temperature and normal-pressure steam overcurrent device, the steam inside the heating cover is heated by the heater. The heated steam enters the interior of the manifold and is finally transported to the corresponding steam-using equipment through the exhaust pipe. The exhaust pipe can increase the discharge rate of the steam, avoiding the situation that the device is damaged due to excessive air pressure inside the manifold caused by steam heating, and also avoiding potential safety hazards caused by excessive air pressure inside the equipment. When the heater needs to be disassembled and repaired, the bolts connecting the installation ring and the installation plate are removed and then the heater can be taken out, achieving the purpose of facilitating the disassembly of the heater and solving the problem that the heating pipe of the existing device is not easy to disassemble, the heating pipe is prone to damage after long-term use, and the whole device needs to be replaced, resulting in a high maintenance cost.

[0016] 2. For this high-temperature and normal-pressure steam overcurrent device, by filling the gasket in the gap between the flange and the heating cover, the sealing performance between the flange and the heating cover can be increased, avoiding steam leakage. The protective cover can protect the heater, avoiding the situation that the top end of the heater overheats and scalds others, and at the same time reducing the heat dissipation of the steam inside the heating cover. Moreover, the heat insulation cover can also insulate the steam inside the heating cover, thereby slowing down the rate of temperature reduction of the steam inside the heating cover.
