Abstract
A self temperature control electric heater of a diesel oil purification device is characterized in that a internal thread nut (2) is fixed at the upper end of the inner chamber of a tubular casing (1), and a heating element (3) is fixed at the middle part thereof; a fixing head (4) is sleeved on the outer wall of the lower end of the tubular casing (1); and a power cord (5) penetrates through the lower end part of the tubular casing (1) and is connected with the heating element (3). In the utility model, a PTC electrothermal element is arranged in the original connecting rod in a diesel filter, thereby not only having no influence on the action of the connecting rod and remaining the integral structure of the filter the same, but also skillfully solving the problem that the filter heats diesel oil from the inside; and the utility model with small loss and high efficiency can be extensively applied to vehicles, ships, submarines and construction machinery which take diesel oil as the motor fuel.
Description
Technical field
The utility model relates to a kind of diesel oil purification plant from the temperature control electric heater.
Background technique
As everyone knows, most of modern project machinery, automobile, warship boats and ships, submarine are all with the diesel oil fuel that is used as power.The diesel oil purification plant is to be serially connected between fuel tank and the motor, diesel oil is carried out the special device of purified treatment.Objectionable impurities in can filtering diesel oil more than 90% guarantees diesel oil cleaning to greatest extent, the protection motor, reduces wear, prolongs motor working life, improve fuel oil utilization ratio, reduce oil consumption, improve exhaust emissions.But under the low temperature environment, the flowability of diesel oil variation causes oil circuit not smooth in the winter time, and diesel oil purification plant and motor can't run well, and must heat to diesel oil.In the prior art at heating equipment power consumption height, the poor stability of diesel oil purification plant.
Summary of the invention
The technical problem that the utility model solves: design a kind of diesel oil purification plant from the temperature control electric heater, the PTC electric heating element is placed in the inner original connecting rod of diesel-oil filter, neither influence the connecting rod effect, keep the filter cleaner overall structure constant, solved the problem that filter cleaner heats to diesel oil internally again dexterously, and heat loss is little, the efficient height.
Mentality of designing of the present utility model:
1, determines PTC electric heating element temperature control curie temperature: select for use the PTC semiconductor chip as heater element, at its base stock BaTiO
3Increase different impurities tin (Sn), strontium (Sr), zirconium (Zr) in the barium titanate, plumbous (Pb) is controlled at the temperature control curie temperature in 80 ℃.Make its highest deep fat temperature≤80 ℃ of adding,, avoid the spontaneous combustion blast away from 280 ℃ of diesel oil burning-points.
2, determine PTC electric heating element initial resistance: the PTC electric heating element has positive temperature coefficient and good current.After the energising of PTC electric heating element, initial electrical resistivity is 10-10
3About Ω .cm, electric current increases sharply with the increase of voltage, and electric current reaches maximum value.When temperature reached setting temperature (curie temperature), resistance was undergone mutation, and resistance increases by 10
3-10
5Doubly, element enters the PTC zone, if voltage continues to increase, electric current reduces on the contrary, and element reaches Maximum operating temperature, and at this moment, the power that the PTC electric heating element is consumed is: P=VI=D (T
1-T
2), in the formula: T1-element surface Maximum operating temperature, T2-heated medium temperature, D-heat release coefficient.By formula as can be seen, the PTC electric heating element changes self-heating power automatically with the variation of external condition.That is to say that when ambient temperature is lower, under the situation many, that element radiating is good of absorbing heat, the heating power of element own is just big, otherwise just little.This characteristic mean the PTC heating element on demand and the supply power, fairly obvious to the electric energy saving effect, compare with other traditional heating elements, this characteristic is that the PTC heating element is distinctive, utilizes this characteristic effectively to bring into play and utilizes the limited electric power resource of car and boat.And power can be regulated automatically, has temperature from the limit ability, needn't increase temperature adjustment, temperature-limiting device in addition.
3, traditional heating mode is the external heating, and shortcoming is that energy consumption is big.The most of heat of heating element looses in filter cleaner surrounding environment space, and a part of heat is absorbed by shell, has only the sub-fraction heat to be used to the diesel oil heating.The utility model places heating element in the inner original connecting rod of diesel-oil filter, so neither influences the connecting rod effect, keeps the filter cleaner overall structure constant, solved the problem that filter cleaner heats to diesel oil internally again dexterously, and heat loss is little, the efficient height.
Technical solution of the present utility model: a kind of diesel oil purification plant is from the temperature control electric heater, the upper end of its tubular shell 1 inner chamber is fixed with internal thread nut 2, the middle part is fixed with heater element 3, be set with fixing head 4 on the outer wall of tubular shell 1 lower end, underpart and heater element 3 that power line 5 passes tubular shell 1 join.
Described heater element 3 is the PTC electric heating element.Described PTC electric heating element temperature control curie temperature≤80 ℃, initial electrical resistivity is 10-10
3Ω .cm
Described fixing head 4 is a tubular bolt, and the bolt head 6 of its lower end surface is fixed on the lower end of tubular shell 1, and the inboard of bolt head 6 is set with seal ring 7.
Be filled with silica gel or magnesia powder 8 between described power line 5 and tubular shell 1 inwall, be fixed with Capsule 9 on the lower end mouth of tubular shell 1, and Capsule 9 be sleeved on the power line 5.
Advantage that the utility model compared with prior art has and effect:
1, the utility model places heating element in the inner original connecting rod of diesel-oil filter, neither influences the connecting rod effect, keeps the filter cleaner overall structure constant, solved the problem that filter cleaner heats to diesel oil internally again dexterously, and heat loss is little, the efficient height.
2, the utility model adopts the heating of PTC electric heating element, and power can be controlled automatically, temperature is strong from limit power, needn't increase temperature adjustment, temperature-limiting device, thermal efficiency height, the flames of anger, safe and reliable in addition.
3, the utility model is energy-efficient, has both solved diesel oil heating and inflammable, the explosive contradiction of diesel oil burning-point low (280 ℃), has solved the contradiction of the rapid temperature raising of diesel oil (power is big) with the limited electric power resource of car and boat again.Be widely used in diesel oil be used as power car and boat, submarine, the engineering machinery of fuel.
