Abstract

The invention discloses a small-sized, low-position sand return machine which can meet the equipment miniaturization requirement of a steel wire cord quenching and fluidizing particle furnace, comprising a machine body, wherein a sand return pipe is arranged on either side of the inner cavity of the machine body, the top of the sand return pipe is communicated with the inner cavity of a furnace body, a sand return cover is arranged at the bottom of the sand return pipe, a fluidizing pipe is arranged below the sand return cover, a middle sand return pipe is also disposed in the middle of the inner cavity of the machine body, the top of the middle sand return pipe is respectively communicated with the sand return pipe on either side, a sand return cover is arranged at the bottom of the middle sand return pipe, and a fluidizing pipe is mounted below the sand return cover. The low-position sand return machine returns the sand from the middle of the inner cavity of the machine body back to the both sides by adding the middle sand return pipe and a sand draining pipe, so that the height of the sand return machine is unnecessary to be very high, thereby the size of the sand return machine can be greatly reduced so as to meet the need of equipment miniaturization.

Description

Low level sand returning machine in the fluidized bed furnace for quenching steel wire of steel wire tire cord

Technical field

The present invention relates to fluidized bed furnace for quenching steel wire of steel wire tire cord, refer more particularly to the low level sand returning machine in the fluidized bed furnace for quenching steel wire of steel wire tire cord.

Background technology

At present, the low level sand returning machine in the fluidized bed furnace for quenching steel wire of steel wire tire cord, its structure comprises: the device body, the both sides of device body inner chamber are respectively arranged with the sand return pipe, the top of sand return pipe communicates with the body of heater inner chamber, and the bottom of sand return pipe is provided with the sand return cover, and the below of sand return cover is provided with the fluidisation pipe.Because the sand at body of heater inner chamber middle part will flow to the sand return of inner chamber both sides sand return pipe, just need allow sand form a natural mobile slope, so just make that whole device height degree is very high, bulky, can't adapt to the miniaturization needs of equipment.

Summary of the invention

A technical problem to be solved by this invention is: provide that a kind of volume is little, the low level sand returning machine in the fluidized bed furnace for quenching steel wire of steel wire tire cord that can adapt to the device miniaturization needs.

For solving the problems of the technologies described above, the technical solution used in the present invention is: the low level sand returning machine in the fluidized bed furnace for quenching steel wire of steel wire tire cord, comprise: the device body, the both sides of described device body inner chamber are respectively arranged with the sand return pipe, the top of sand return pipe communicates with the body of heater inner chamber, the bottom of sand return pipe is provided with the sand return cover, the below of sand return cover is provided with the fluidisation pipe, sand return pipe in the middle of the middle part of device body inner chamber also is provided with, the top of middle sand return pipe is connected to the both sides sand-ejecting tube respectively with two, the bottom of middle sand return pipe is provided with the sand return cover, and the below of sand return cover is provided with the fluidisation pipe.

The invention has the beneficial effects as follows: the present invention is by sand return pipe, fluidisation pipe and sand-ejecting tube in the middle of increasing, sand is returned both sides from the middle part of device body inner chamber, it is very high to make that the height of sand returning machine does not need, and has so just reduced the volume of sand returning machine greatly, makes it can satisfy the needs of device miniaturization.

Fig. 2 is an A-A sectional structure synoptic diagram among Fig. 1;

Among Fig. 1 to Fig. 2: 1, heating zone, 2, cooling section, 3, the sand return pipe, 4, the sand return cover, 5, the fluidisation pipe, 6, middle sand return pipe, 7, the sand return cover, 8, the fluidisation pipe, 9, sand-ejecting tube, 10, the device body.

Embodiment

Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.

As shown in Figure 2, low level sand returning machine in the fluidized bed furnace for quenching steel wire of steel wire tire cord of the present invention, comprise: device body 10, the both sides of described device body 10 inner chambers are respectively arranged with sand return pipe 3, the top of sand return pipe 3 communicates with the body of heater inner chamber, the bottom of sand return pipe 3 is provided with sand return cover 4, the below of sand return cover 4 is provided with fluidisation pipe 5, sand return pipe 6 in the middle of the middle part of device body 10 inner chambers also is provided with, the top of middle sand return pipe 6 with two respectively the sand-ejecting tube 9 to both sides be connected, the bottom of middle sand return pipe 6 is provided with sand return cover 7, and the below of sand return cover 7 is provided with fluidisation pipe 8.During practical application, as shown in Figure 1, the heating zone 1 of fluidized bed furnace for quenching steel wire of steel wire tire cord links to each other with a low level sand returning machine respectively with cooling section 2, the sand return pipe 3 of low level sand returning machine respectively with the body of heater intracavity inter-connection of corresponding heating zone 1 and cooling section 2.

The present invention is by sand return pipe 6, fluidisation pipe 8 and sand-ejecting tube 9 in the middle of increasing, sand is returned both sides from the middle part of device body 10 inner chambers, it is very high to make that the height of sand returning machine does not need, and has so just reduced the volume of sand returning machine greatly, makes it can satisfy the needs of device miniaturization.

Claims
