Abstract
The utility model relates to an automatic constant-temperature heating device for a hopper of a coal bunker, which is widely applicable to coal bunkers of coal storage systems at cold areas, and capable of effectively preventing a coal bunker from arching and blocking due to icing of coal in a hopper part of the coal bunker due to cold weather and high coal water content. According to the principle of carbon fiber electric heating, interior temperature of the hopper of the coal bunker is controlled through a microcomputer temperature control system, so that automatic constant-temperature heating for the hopper of the coal bunker is achieved. The automatic constant-temperature heating device is simple in system, convenient in mounting, capable of automatic control, low in operation cost, and capable of effectively guaranteeing the temperature of the hopper part of the coal bunker to be within a set range, so that the coal in the hopper part can be prevented from being iced into ice blocks to block the coal bunker, natural feed of the coal is guaranteed, reliability in use of the coal bunker is improved, and the automatic constant-temperature heating device has practical popularization and application values.
Description
Affiliated technical field
The utility model relates to a kind of later-model coal store funnel automatic constant-temperature heating system, can be widely used in severe cold area coal storage system coal store, can effectively prevent to belong to the technical field that coal industry coal stores auxiliary facilities owing to intemperance, the high coal store funnel part coal that causes of ature of coal moisture freeze and cause the coal store arch camber to be stopped up.
Background technology
Severe cold area, the silo coal storage is adopted in coal mine ground system, coal preparation plant, coal logistics coal blending center, power plant fields such as (Coal Chemical Industries) mostly, because the moisture height of coal, coal coal storage time in the silo storehouse is longer, cause coal in funnel part slagging scorification, icing serious, form and freeze coal, arch camber is stopped up, cause the silo can not coal supply, have a strong impact on system's operation; At present main in scale removal process, the easy slump of coal jeopardizes personal safety and damage equipment by the labor cleaning, and this accident all has generation every year.Produced the idea of coal store funnel automatic constant-temperature heating system this respect research in this case, gone to overcome the above problems.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, easy construction, fast, the automatic constant-temperature of heating, makes the coal store funnel remain on the temperature of setting, prevents that funnel part from forming the automatic constant-temperature heating system that freezes coal.
The technical scheme that its technical matters that solves the utility model adopts is:
Utilize carbon fiber (2) to be laid on coal store funnel (1) inwall, by carbon fiber (2) heating power heating, the temperature of utilizing The System of Temperature-controlling Microprocessor (5) to control coal store funnel (1) inwall is no more than or is not less than the temperature of setting, realize that the coal store funnel part keeps constant temperature, prevent to form and freeze coal, the storehouse is blocked up in arch camber.In order to prevent that carbon fiber (2), temperature sensor (4) from being smashed by material, at coal store funnel inwall laying high-strength degree wear-resistant material protective cover (3).
The beneficial effects of the utility model are:
1, first the carbon fiber heating technology is applied on the coal store funnel, solves the problem that coal store inside can't heating.
2, utilize temperature sensor to detect coal store funnel temperature inside, adopt The System of Temperature-controlling Microprocessor to realize heating automatically, realize automatic constant-temperature, the degree of automation height.
3, utilize the heating of carbon fiber heating power, heating is fast, and highest temperature is no more than 90 ℃, homogeneous heating, and construction is simple simultaneously.
Description of drawings
Accompanying drawing is a system schematic of the present utility model
Above-mentioned number in the figure is described as follows:
1, coal store funnel 2, carbon fiber 3, high strength anti abrasive material protective cover
4, temperature sensor 5, The System of Temperature-controlling Microprocessor 6, electric cabinet
The specific embodiment
The utility model be carbon fiber (2) one terminations from electric cabinet (6), another part is laid on coal store funnel (1) inwall, energising back carbon fiber (2) heating realizes coal store funnel (1) heating.
Temperature sensor (4) is installed on coal store funnel (1) inwall, detect the temperature of coal store funnel (1), contactless switch by The System of Temperature-controlling Microprocessor (5) control electric cabinet (6), whether control carbon fiber (2) switches on, guarantee that the temperature of coal store funnel inwall is no more than or is not less than the temperature of setting, realize automatic constant-temperature, prevent that the coal in the coal store funnel (1) from freezing into piece, arch camber is stopped up.
Carbon fiber (2) on coal store funnel (1) inwall, temperature sensor (4) inside face laying high-strength degree wear-resistant material protective cover (3) prevent from that coal from pounding to decrease carbon fiber (2) and temperature sensor (4).
Claims (1)
1. coal store funnel automatic constant-temperature heating system, mainly form by carbon fiber, temperature sensor, The System of Temperature-controlling Microprocessor and electric cabinet, it is characterized in that: lay carbon fiber at coal store funnel inwall, the carbon fiber heating power, by The System of Temperature-controlling Microprocessor be embedded in temperature in the temperature sensor control coal store funnel of funnel inwall, realize the heating of coal store funnel automatic constant-temperature.
