Description

Technical Field

[0001] The utility model relates to a heating device, in particular to a circulating heater for preventing dust deposition. Background Art

[0002] A circulating heater is a common device for heating fluids. It can circulate and heat liquids or gases to keep them at a constant temperature. It usually consists of a heater, a circulation pump, and a temperature controller, and its working temperature can be adjusted between -60°C and 400°C, so it has very wide applicability in different application scenarios.

[0003] In the prior art, the circulating heater basically does not have a dust-proof structure. After long-term use, a large amount of dust may adhere to the inside of the device, which will not only affect the working efficiency of the heater, but also may cause a certain degree of loss to the high-temperature resistance wire inside the device. Summary of the Utility Model

The left and right ends of the circulating heater body are respectively provided with access ends, and the access ends are both attached to the left and right inner walls of the housing. A hot air pipe is inserted into each access end and is connected in a through manner. The upper and lower ends of the housing are respectively provided with a chassis. Dust monitors are provided at the upper end of the left inner wall and the lower end of the right inner wall of the housing. A group of electrostatic adsorption blades are laid at the top and bottom inside the housing. The dust monitor and the kinetic energy converter are both connected to the remote control end through a sensing line. A kinetic energy converter is installed in the chassis, and the electrostatic adsorption blades are connected to the kinetic energy converter in the chassis through a pipeline.

[0006] Further, a multi-stage filter is installed above the kinetic energy converter and is connected by a pipeline.

[0007] Further, a return conduit is inserted on the upper right side of the multi-stage filter, and a plurality of filter plates are sequentially laid from bottom to top in the multi-stage filter and the filtering specifications decrease successively.

[0008] Further, the other end of the return conduit is inserted into the housing.

[0009] Further, one end of the hot air pipe extends out of the housing and is equipped with a matching dust-proof baffle.

[0010] In summary, the beneficial effects of the present application are as follows:

[0011] 1. By providing a dust monitor, electrostatic adsorption blades, kinetic energy converters, multi-stage filters, return ducts, hot air ducts, and dust-proof partitions, the circulating heater is equipped with a dust-proof structure, enabling the adsorption and filtration of dust, effectively preventing dust from depositing on the circulating heater body, reducing the amount of dust inside the device, improving the working efficiency of the circulating heater body, reducing the loss of the high-temperature resistance wire inside the circulating heater device, and extending the service life of the circulating heater body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The present application will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only for explaining the relevant utility model and not for limiting the utility model. Additionally, it should be noted that for the sake of description, only parts related to the utility model are shown in the drawings.

[0017] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and embodiments.

[0018] As Figure 1 and Figure 2As shown in the figure, a circulating heater for preventing dust deposition is provided. The circulating heater body 1 is placed inside the housing 2. The left and right ends of the circulating heater body 1 are respectively provided with access ends 101, and the access ends 101 are both mounted on the left and right inner walls of the housing 2. A hot air pipe 9 is inserted on each access end 101 and is connected in a through manner. The upper and lower ends of the housing 2 are respectively provided with a chassis 5. Dust monitors 3 are provided at the upper end of the left inner wall and the lower end of the right inner wall of the housing 2. A group of electrostatic adsorption blades 4 are laid at the top and bottom inside the housing 2. The electrostatic adsorption blades 4 are connected in a through manner with a kinetic energy converter 6 inside the chassis 5 by a pipeline. A kinetic energy converter 6 is installed inside the chassis 5. A multi-stage filter 7 is installed above the kinetic energy converter 6 and is connected by a pipeline. A return conduit 8 is inserted on the upper right side of the multi-stage filter 7. The other end of the return conduit 8 is inserted into the housing 2. One end of the hot air pipe 9 extends out of the housing 2 and is equipped with a matching dust-proof baffle 10.

[0019] Embodiment 1:

[0020] As Figure 1 and Figure 2 As shown in the figure, when the circulating heater body 1 is running, the dust index inside the housing is monitored in real time by the dust monitor 3. When the dust index exceeds the standard, the kinetic energy converter 6 inside the chassis 5 is started. The kinetic energy converter 6 drives the electrostatic adsorption blades 4 to adsorb the dust on the circulating heater body inside the housing 2, and then transmits it to the multi-stage filter 7 through a pipeline. A plurality of filter plates are laid in sequence from bottom to top inside the multi-stage filter 7 and the filtering specifications decrease successively, which can perform multi-stage adsorption and filtration on the dust in the inhaled hot air. After dust removal, the hot air is sent back into the housing through the return conduit 8. When the heat is output through the hot air pipe 9, the dust-proof partition 10 blocks the external dust. The circulating heater has a dust-proof structure. The circulating heater body 1 can operate at a high speed, improving the working efficiency of the circulating heater body, realizing the adsorption and filtration treatment of dust, effectively avoiding the deposition of dust on the circulating heater body, reducing the amount of dust inside the equipment, reducing the loss of the high-temperature resistance wire inside the circulating heater equipment, and increasing the service life of the circulating heater body.
