Abstract

The utility model relates to a constant temperature pressure cooker device for industry, which is formed by up and down combining two pressure cookers with identical structures. A cooker clamp is a circular cylinder, one end is opened, and the other end is sealed. The sealing end of a cooker body is provided with a fixing column so that an electric heating device can be arranged. The inner margin of a metal disk is provided with an electric heating pipe to supply heat energy; the center of the disk is provided with a blast fan of a stirring device, and the drive shaft thereof, which extends out of the cooker body, is connected with an electrical motor. When the blast fan rotates, the cooker body compresses air to keep a constant temperature; the accuracy is within 3 DEG C above or below zero, and the testing accuracy can be ensured.

Description

Industrial constant temperature pressure kettle device

The utility model relates to a kind of industrial constant temperature pressure kettle device, belongs to the technical field of pressure cooker.

Existing pressure kettle is because airtight fully, heating power that installing electric heater produces in it, can not uniform distribution in the difference of this temperature of each corner location, be everlasting ± more than 5 ℃, even reach ± 10 ℃ of inaccuracy as a result that make the electronic component or the assembly of test, influence quality of product.

The purpose of this utility model is that a kind of industrial constant temperature pressure kettle device will be provided, and it can overcome above-mentioned shortcoming, mainly in the pot body stirring apparatus is housed, and is driven its pressurized air 5kg/cm by variable speed electric motors, particularly ³More than, make temperature constant remain ± 3 ° in, can satisfy the needs of industrial test.

The purpose of this utility model is achieved in that a kind of industrial constant temperature pressure kettle device, this device 3 has identical in

Now in conjunction with the accompanying drawings the structure of industrial constant temperature pressure kettle device is described in detail:

By Fig. 1, constant temperature high pressure temperature boiler plant is combined between the higher and lower levels by the identical pressure cooker of structure (1) and (2) and becomes one, be respectively equipped with top, Qianmen, Qianmen (4) (4) in the front and be provided with instrument panel, there is temperature controller (5) timer (6) can set service time on the plate, the speed regulator 7 of levelling speed of agitator, the pressure gauge 8 that shows pressure cooker 3 internal pressures, pressure indicator light 10 in the time of after setting pressure is finished in the pressure cooker 3, pressure when setting pressure is finished in the pressure cooker 3 refers to lamp 11, the temperature indicator 12 that setting temperature is finished in the pressure cooker, show the stirring tutorial light 13 in the stirring operation, show that green light 15 start buttons 16 and the power switch of finishing 17 operated in caution red light 14 indications of fault.

By Fig. 1-4, in the Qianmen 4 in the box-shaped spaces in conjunction with pressure cooker 3 by pot body 18, pot door device 19, electric heater 20, stirring apparatus 21 is formed.

Pot body 18 is one one end openings, the garden tube that the other end is airtight, level is horizontally-arranged in the box-shaped space, its opening end is provided with annular framework 22, its outer peripheral edge has screw thread, can load onto a lock ring 23, a chimeric therebetween packing ring 24, be used for door body 9 contacts of pot door device 19 and prevent that seepage, lock ring 23 peripheries are provided with the handle 25 of symmetry.

Can rotate lock ring 23 and the door body 9 of locking pot door device 19 with hand, can be with pot body 18 opening portions airtight or open, be provided with the breach 26 that the shape ring is arranged interior week, make the periphery double wedge 27 of a body 9 can be chimeric, rotate the opening end of lock ring 23 locking door bodies 9 at lock body 18, pot door device 19 is made up of door body 9 and carriage 28, door body 9 also is a garden shape, can match with pot body 18 opening ends, its periphery has the breach 26 of double wedge 27 and lock ring 23 to match and chimeric, the outer rim middle part has a projection 29 to cooperate with carriage 28, available bolt 30 is fixed on the vertical frame 31 of carriage 28, the right angle frame that carriage 28 is L-shaped, the vertical frame 31 of tool is in conjunction with door body 9, crossbearer 32 is incorporated between the set plural pair roller 33 in both sides in the box-shaped space, holds handle 34 on the vertical frame 31 and can promote carriage 28 and drive the 9 front and back displacements of door bodies, solid and generator gate body 9 opens and closes the effect of pot bodies 18.

By Fig. 3, electric heater 20 has several fixed bolts 35 to be fixed on pot body 18 interior sealed end, and garden shape metal dish 16 edge within it props up electric heating tube 37 again in conjunction with number, is used for supplying heat energy in the pot body 18.There is the pulley fan 38 of stirring apparatus 21 in metal dish 16 central authorities, are used for making stirring each part in the pressurized gas flow direction pot body 18 that is heated, and reach the effect of pot body 18 inner high voltage gas constant temperature precision in 23 ℃.
