Abstract

The utility model relates to a disk type vibrating dreg cooling machine and is the dreg exhausting device for the cyclic fluidized bed boiler. The utility model aims at solving the problem that the heat exchanging surface of the prior dreg cooling device is easy to become worn and torn and the vibrating dreg cooling machine has an uneven delamination. The utility model consists of a dreg cooling device(5) and a driving device(2). The utility model is characterized in that the balancing body(11) of the driving device(2) is provided with a vibrating motor(3); the bottom of the balancing body(11) is provided with a damping spring(1); the top part of the balancing body(11) is connected with the dreg cooling device(5) through a lead spring(6) and a helix spring(4); a slag passage(15) of the dreg cooling device(5) is formed between the disk type water jacket(16); the transition plate(14) connects the upper and lower neighboring two disk shaped water jacket(16) to form a slag passage(15); and the slag passage(15) is respectively connected with the dreg outlet(8) and the dreg inlet(10).

Description

The disc type vibration-type slag cooling machine

Technical field:

The utility model is the slag removal equipment of CFBB.

Background technology:

Existing CFBB slag removal equipment mainly contains the cold slag machine of spiral, barrel slag cooler, bubbling bed slag cooler etc., the cold slag heat-transfer surface of cold slag equipment of these types very easily weares and teares, cause that maintenance of equipment is undue frequent, equipment life short, be difficult to operate as normal, thereby influence the smooth and easy deslagging of boiler, influence boiler efficiency, be forced to carry out the accident deslagging, cause environmental pollution.Some novel devices have appearred in this field successively, and as vibration-type slag cooling machine, it mainly is made up of heat-exchanger rig, drive unit, and heat-exchanger rig is taked multilevel access version, and slag portion within it is cooled during by cold slag heating surface to the previous crops sling movement.This cold slag machine has solved the wear problem of cold slag heat-transfer surface preferably, but because the restriction of structure, the equipment that is used for putting into practice be difficult to slag ideally wire screen (these aspects are in parallel to each aspect, the aspect of no slag or few slag is equivalent to not be fully utilized), the cold slag effect of the equipment that weakened so greatly.The essence of the type equipment belongs to two plastid Near resonance oscillating conveying machineries, is used for behind the cold slag machine because heat-exchanger rig weight is big, and equipment is difficult to maximize, so the scope of application is affected, and is difficult to and the supporting use of large-scale CFBB.

The utility model content:

The utility model is exactly that the heat-transfer surface that solves present cold slag device very easily weares and teares, the uneven problem of vibration-type slag cooling machine layering, the disc type vibration-type slag cooling machine of provide a kind of heat-transfer surface wearing and tearing of cold slag device little, vibration-type slag cooling but slag need not layerings, volume is little.

The utility model adopts following technical scheme: the utility model comprises cold slag device, drive unit, its structural feature is that the balanced body of drive unit is provided with vibrating motor, the bottom of balanced body is provided with shock-absorbing spring, and the top of balanced body links to each other with cold slag device with guiding leaf spring, helical spring; Form the slag passage of cold slag device between the disc water jacket, with rebound two neighbouring disc water jackets are connected to a slag passage, the same respectively slag notch of slag passage, slag inlet connect.

The beneficial effects of the utility model:

1. because the utility model is to drive the cold slag device motion with guiding leaf spring, helical spring, just make the slag in the cold slag device do sling movement along circumference, cold slag passage wearing and tearing to cold slag device are very little, therefore equipment life is long, maintenance load is little, possess the basic condition that moves continuously with boiler, can improve boiler efficiency, improve boiler room and peripheral working environment simultaneously;

2. each of cold slag device layer slag passage finally is concatenated into a longer slag passage, slag is from top to bottom successively passed by in order, the problem that does not have the slag layering, each cold slag blanket face all can be fully utilized, simultaneously because slag operation passage is long, slag cool time so slag good cooling results have been increased;

3. this utility model compact conformation, profile little (be equivalent in the past exert oneself on an equal basis vibration-type slag cooling machine length about 1/3rd) is therefore on-the-spot take up an area of few, save construction investment, and can solve the slag cooling problem of large-scale circulation fluidized bed boiler well in the mode of a stove polygamy.

4. because cooling water is provided with independent disc water jacket, and cooling water does not directly contact with slag, and cooled slag remains dried slag, and this slag activity is good, be convenient to comprehensive utilization.

Fig. 2 is the B-B cutaway view of Fig. 3;

Fig. 3 is the A-A cutaway view of Fig. 2;

Fig. 4 is the vertical view of Fig. 1.

The specific embodiment:

The utility model comprises cold slag device 5, drive unit 2, and the balanced body 11 of drive unit 2 is provided with vibrating motor 3, and the bottom of balanced body 11 is provided with shock-absorbing spring 1, and the top of balanced body 11 links to each other with cold slag device 5 with guiding leaf spring 6, helical spring 4; Form the slag passage 15 of cold slag device 5 between the disc water jacket 16, with rebound 14 two neighbouring disc water jackets 16 are connected to a slag passage 15, slag passage 15 connects with slag notch 8, slag inlet 10 respectively.

Also can be respectively arranged with air outlet 9, air inlet 13, to increase the cooling effect of slag in the slag passage 15 of the top of cold slag device 5 and on the slag passage 15.

Below in conjunction with a description of drawings course of action of the present utility model:

At first the Vibration on Start-up motor 3, slag is in slag inlet 10 enters slag passage 15, because the effect of guiding leaf spring 6, helical spring 4, slag is done sling movement along circumference in the disc water jacket 16 of cold slag device 5, fall within on lower floor's cold slag disc water jacket 16 through rebound 14, slag in cold slag device 5 along slag passage 15, discharge by slag notch 8.When moving with slag, cooling water is discharged through delivery port 7 through water inlet 12, disc water jacket 16 again.

If in water-cooled simultaneously, also air-cooled, cooling air enters slag passage 15 through air inlet 13 and directly contacts with slag, discharge through air outlet 9 again.
