Description

Technical Field

[0001] The utility model relates to the technical field of flame detectors, and particularly relates to a cooling device for a flame detector. Background Art

[0002] As an important industrial safety device, the flame detector is widely used in various combustion systems. However, during long-term operation, the flame detector is vulnerable to the influence of high-temperature environments, resulting in performance degradation or even damage.

[0003] Publication No. CN218495400U discloses a cooling device for a flame detector, which relates to the technical field of flame detectors and includes a boiler wall, a flame detector, and a cooling box. A fixing block is arranged on one side of the boiler wall, one end of the flame detector is fixedly connected with a probe body, and a cooling cylinder is arranged on the surface of the flame detector. The beneficial effects of the utility model are as follows: the coolant in the inner cavity of the cooling box is cooled by a semiconductor refrigeration sheet, and the coolant in the inner cavity of the cooling box is pumped by the cooperation of a micro water pump and a liquid suction pipe, enters the inner cavity of a heat exchange pipe through an infusion pipe, the heat exchange pipe is used to cool the flame detector, and the coolant returns to the inner cavity of the cooling box through a liquid return pipe to form a cycle. Since the flame detector is connected to the probe body, the heat of the flame detector and the probe body can be conducted, and thus the probe body can be cooled, solving the problem that the internal components of the flame detector are damaged due to long-term operation in a high-temperature environment.

[0004] This device uses a heat exchange pipe to cool the flame detector. However, due to the relatively high ambient temperature around the flame detector, while the heat exchange pipe exchanges heat with the flame detector, it also exchanges heat with the surrounding ambient temperature. As a result, the coolant inside the heat exchange pipe will rapidly heat up, causing the coolant in the latter half of the heat exchange pipe to be in a high-temperature state and unable to exchange heat with the flame detector, resulting in a low cooling effect on the flame detector.

[0005] Therefore, it is necessary to invent a cooling device for a flame detector to solve the above problems. Summary of the Utility Model

The cooling mechanisms include a micro circulating pump 25, a cooling box 26, a cooling cylinder 3, a first circulation pipeline 35 and a second circulation pipeline 36. The rear end of the cooling cylinder 3 is fixedly connected to the fixed support 2. The cooling cylinder 3 from the outside to the inside is successively a first fixing plate 31, a second fixing plate 32 and a heat conducting plate 33. A heat insulation layer 34 is fixedly connected between the first fixing plate 31 and the second fixing plate 32. The inner side of the heat conducting plate 33 is provided with an installation groove 37. A flame detector body 4 is fixedly installed in the installation groove 37. The transmission line at the rear end of the flame detector body 4 penetrates through the insertion hole 27 and extends to the outside of the furnace body.

[0033] Among them, the cooling cylinder 3 is installed on the front side of the fixed support 2, the cooling box 26 is fixed on the rear side of the fixed support 2, then the flame detector body 4 is installed in the installation groove 37, and then the fixed support 2 is connected to the furnace wall 1, so as to fix the cooling cylinder 3 and the flame detector body 4 on the inner side of the furnace body. At this time, the flame detector body 4 monitors the internal flame state in real time.

[0034] Meanwhile, during use, the heat insulation layer 34 divides the cooling cylinder 3 into inner and outer sides. The first circulation pipeline 35 on the outer side exchanges heat with the surrounding environment, and cooperates with the heat insulation layer 34 to reduce the influence of external heat on the inner second circulation pipeline 36, so that the coolant inside the second circulation pipeline 36 can always be at a relatively low temperature, exchange heat with the flame detector body 4, improve the heat exchange effect on the flame detector body 4, and thus effectively improve the use safety of the flame detector body 4.

[0035] Refer to Figures 3 to 6 , the first circulation pipeline 35 is fixedly connected to the outer surface of the first fixing plate 31, the second circulation pipeline 36 is fixedly connected to the inner surface of the second fixing plate 32, the outer surface of the heat conducting plate 33 abuts against the surface of the second circulation pipeline 36, the inner surface of the heat conducting plate 33 abuts against the surface of the flame detector body 4, the rear end of the first circulation pipeline 35 is fixedly connected with a first liquid inlet pipeline 21 and a first liquid discharge pipeline 23, the rear ends of the first liquid inlet pipeline 21 and the first liquid discharge pipeline 23 both penetrate through the fixing bracket 2, the cooling box 26 is fixed to the rear side of the fixing bracket 2, the micro circulation pump 25 is fixedly installed at the right front position of the cooling box 26, the rear end of the first liquid discharge pipeline 23 is fixedly connected to the cooling box 26, the rear end of the first liquid inlet pipeline 21 is fixedly connected to the micro circulation pump 25, the rear end of the second circulation pipeline 36 is fixedly connected with a second liquid inlet pipeline 22 and a second liquid discharge pipeline 24, the rear ends of the second liquid inlet pipeline 22 and the second liquid discharge pipeline 24 both penetrate through the fixing bracket 2, the rear end of the second liquid inlet pipeline 22 is fixedly connected to the first liquid inlet pipeline 21, and the rear end of the second liquid discharge pipeline 24 is fixedly connected to the first liquid discharge pipeline 23.

At the same time, the heat insulation layer 34 blocks the external heat again, effectively reducing the influence of external heat on the inner second circulation pipeline 36. At this time, the coolant is transported into the second circulation pipeline 36 through the second liquid inlet pipeline 22, and the second circulation pipeline 36 cooperates with the heat conducting plate 33 to exchange heat with the flame detector body 4.
