Abstract
The utility model discloses a glue removing device for soft magnet ferrite sintering kilns, which has the main structure that a closed passage is composed of a kiln chamber 2, a heating chamber 1, an air supply pipe and a sealed cover 4; a centrifugal fan 3 is arranged between the kiln chamber 2 and the air supply pipe 5; a heater 6 and a thermal couple 7 are arranged in the heating chamber 1; both sides of the kiln chamber 2 are provided with a gas sampling hole 8, a fuel device 10 and an air intake valve 9. The device is used for removing glue in the sintering process of soft magnet ferrite. The utility model can effectively control the temperature, the air velocity and the air quantity of the glue removal of products in sintering process, and can cause products to be uniformly heated and to be completely removed glue.
Description
Technical field
The utility model relates to the intensification batching out unit that is used for soft magnetic ferrite sintering process in tunnel cave.
Technical background
Soft magnetic ferrite sintering process in tunnel cave is divided binder removal, intensification, insulation, cooling four-stage, and binder removal is that first road of sintering process closes, and has only binder removal abundant, could go out quality height, consistent good product by sintering.Binder removal is exactly to be beneficial to the bonding agent that blank makes (be commonly called as glue, soft magnetism industry PVA commonly used makees binding agent) and to vapor away being used for bonding powder in the product, and the concentration of binder removal effect and environment temperature, wind speed, the interior glue of air, the size of product are relevant.The binder removal method of kiln mainly was in kiln chamber bottom or bottom and top are provided with heater in the past, by coming heating products and binder removal based on the method for radiation, the result who does like this is that be heated inequality, binder removal of the product in the kiln chamber is insufficient, and consistency of product is poor, and the energy consumption height.
Technology contents
The purpose of this utility model is, designs a kind of soft magnetic ferrite sintering kiln batching out unit, and it can make, and blank is heated evenly, binder removal is abundant, to improve the sintering character and the uniformity of product.
The technical solution of the utility model is, described soft magnetic ferrite sintering kiln batching out unit has the kiln chamber, described kiln chamber and heating clamber, ajutage and seal closure are formed closed channel, between kiln chamber and the ajutage centrifugal blower is arranged, there are gas sampling hole, burner, air admission hole in both sides, described kiln chamber, described heating clamber has thermocouple, and described sealing is covered with venthole.
Below make and further specifying.
Fig. 1 is a practical structures of the present utility model.As known in the figure, the utility model has kiln chamber 2, closed channel is formed with heating clamber 1, ajutage 5, seal closure 4 in described kiln chamber 2, it is characterized in that, between kiln chamber 2 and the ajutage 5 centrifugal blower 3 is arranged, centrifugal blower 3 is contained in the seal closure 4, having heaters 6 and thermocouple 7 in the described heating clamber 1, there are gas sampling hole 8, burner 10, intake valve 9 in 2 both sides, described kiln chamber, on the described seal closure 4 air bleeding valve are arranged.Described heating clamber 1, ajutage 5 usefulness refractory materials are made as suitable.
The design principle of the utility model technology is, its key problem in technology is the circulation canal that can form a high-temperature gas, make the gas of uniform temperature and certain flow rate pass the kiln chamber repeatedly, carry out heat exchange with product in the heat exchange mode of convection current, conduction and the kiln chamber, make product in the kiln chamber be able to even heating, abundant binder removal, and make product by heating, binder removal controlled.
As shown in Figure 1, kiln chamber 2 is the product loading area, is the passage of kiln, and heating clamber 1 is below the kiln road, and two ajutages are on the one side in kiln chamber 2; Whole device is except that seal closure 4, and structure material is refractory material, has good high-temperature intensity and life-span.Gas circulates by arrow points under the effect of centrifugal blower.During gas process kiln chamber 2,, after product is heated, the colloid in it is discharged the product by heating in the kiln chamber.The gas that passes the kiln chamber enters two ajutages under fan action, deliver to the heating clamber heating again, enters kiln chamber 2 after the heating again, the circulation that gas does not so stop, and the product in the kiln chamber 2 just can obtain sufficient soaking, and the colloid in the product is discharged completely.
Because the product difference, gas temperature, flow velocity, flow during binder removal in the kiln are also different.The temperature available heat galvanic couple 7 of gas and heater 6 controls can be provided with arbitrarily; The flow velocity of gas, flow can by to centrifugal blower frequency control control, also can control arbitrarily.The gas gel content can be come sampling Detection by the gas sampling hole 8 of kiln chamber 2 one sides in the kiln, according to gas gel content height, can adjust the openings of sizes of the air bleeding valve 11 on the seal closure 4, and regulate the higher gas discharge rate of gel content with this, the gas of discharging mends fresh air by the intake valve 9 of kiln chamber 2 opposite sides, keeps the relatively stable of kiln internal gas pressure with this; Heater 6 can provide 800 ℃-1000 ℃ localized hyperthermia, makes that colloid through this place is burned to be fallen, and can effectively reduce the gel content of gas in the kiln.
As known from the above, the utility model is the soft magnetic ferrite sintering kiln batching out unit, and it can be according to technological requirement, and the binder removal of control product easily and effectively accomplishes that homogeneous heating, binder removal are complete, for the soft magnetism product of sintering character height, high conformity provides safeguard.
Description of drawings Fig. 1 is a kind of embodiment sectional structure of the utility model (is among Fig. 2 A-A to analysing and observe); Fig. 2 be among Fig. 1 B-B to sectional structure; Arrow points is that gas circulates direction under the centrifugal blower effect among the figure.In the drawings: 1---heating clamber, 2---kiln chamber, 3-centrifugal blower, 4-seal closure, 5-ajutage 6---heater, 7---thermocouple, 8---gas sampling hole, 9---intake valve, 10---intake valve, 11---air bleeding valve, 12---heat-insulation layer, 13---metal shell.
The specific embodiment
By utility model device shown in Figure 1, on the tunnel cave of sintering soft magnet body, can carry out some utility model device shown in Figure 1 combinations by the specification requirement of tunnel cave, form the binder removal district of tunnel cave.The utility model device serviceability temperature is decided by the temperature that centrifugal blower can bear.Heating clamber 1 is the bridge pier type structure.Burner 10, heater 6 usefulness resistance wires are manufactured; Thermocouple 7, air bleeding valve 11, intake valve 9 market purchasings; The motor of centrifugal blower 3 is a frequency control motor, and impeller is a stainless steel; Seal closure 4 is a stainless steel; Ajutage 5 is special-shaped hollow pipe.The described closed channel of device is built with refractory material.
