Specific embodiment
First embodiment
As depicted in figs. 1 and 2, the steam type airheater of the automatic ash removing include shell 100, the first filter screen 200,
Second filter screen 300 and preheater tube bank 500.
As shown in Figure 1, the left end of shell 100 is air inlet, right end is air outlet, is additionally provided on the side wall of shell 100
The heat carriers such as preheater tube bank 500, preheater tube bank 500 are heated to institute for heating to the gas by shell 100
The technological temperature needed.
As shown in Fig. 2, the shape of the first filter screen 200 and the second filter screen 300 shape with 100 cross section of shell respectively
Unanimously, in the present embodiment, the first filter screen 200 and the second filter screen 300 are rectangle respectively, but not limited to this, further include
Round, triangle or square etc..First filter screen 200 and the second filter screen 300 respectively with the air inlet phase of shell 100
Neighbour is filtered the gas entered inside shell 100 first, is then heated again by preheater tube bank 500, effectively prevent gas
Body black dirt is accumulated on 100 inner wall of shell, and needs the dust inside blowing out shell 100.
The first opening and the second opening are set on the side wall of shell 100, and the first filter screen 200 can be inserted by the first opening
Enter inside shell 100, the gas by shell 100 is filtered to realize；Second filter screen 300 can also pass through
Two openings are inserted in inside shell 100, are filtered to realize to the gas by shell 100.As it can be seen that the first filter screen
200 can individually remove outside shell 100 relative to the second filter screen 300, and similarly, the second filter screen 300 can be relative to the
One filter screen 200 removes outside shell 100.It follows that when product completely excessive dust on the first filter screen 200, the first filtering
Net 200 can be removed by the first opening to shell 100, meanwhile, the second filter screen 300 is moved into shell by the second opening
Inside 100, at this point, can clear up the first filter screen 200 moved to outside shell 100.Pass through the first filter screen 200 and
Two filter screens 300 are used cooperatively, while guaranteeing to be filtered the gas entered inside shell 100, moreover it is possible to effectively to mistake
Strainer is cleared up, and easy to use.
In the present embodiment, the first filter screen 200 and the second filter screen 300 are in the same plane, and adjacent connection, i.e.,
First filter screen 200 and the second filter screen 300 are in that integration and the first opening and the second opening are separately positioned on shell 100
Opposite two sides.In this way, when the first filter screen 200 is advanced into 100 inside of shell by the first opening, first filter screen
200 the second filter screens 300 of promotion are moved to outside shell 100 by the second opening, at this point, can to move to outside shell 100 the
Two filter screens 300 carry out dust cleaning.Similarly, the second filter screen 300 after cleaning is advanced into shell 100 by the second opening
Portion, which pushes the first filter screen 200 to move to outside shell 100, at this point, can carry out to the second filter screen 200
Cleaning.Make the easy switching of the first filter screen 200 and the second filter screen 300, also, prevents the first filter screen 200 and the second mistake
In the handoff procedure of strainer 300, the dust of gas passes through between the first filter screen 200 and the second filter screen 300, prevents from filtering
The decline of effect.
As shown in Figure 1, the steam type airheater of the automatic ash removing further includes spray equipment 400, spray equipment 400
In the outside of shell 100, for remove to outside shell 100 the first filter screen 200 and the second filter screen 300 spray
Cleaning.By the way that spray equipment 400 is arranged, cost of labor is saved, also, effectively promote cleaning efficiency.
Spray equipment 400 includes multiple spray heads, and multiple spray heads can cover entire strainer.Multiple spray heads can also
It is enough to execute mobile and rotation etc., it can be fully cleaned with each place to filter screen.Wherein, movement can be driven by cylinder, rotation
Turn to be driven by a motor rotation.
It should be noted that spray to the first filter screen 200 and the second filter screen 300 by spray equipment 400 clear
It washes, therefore, the waterproof and strength character of the first filter screen 200 and the second filter screen 300 will be got well, in the present embodiment, the first mistake
Stainless steel can be used in the material of strainer 200 and the second filter screen 300, by using stainless steel material, effectively prevent getting rusty and by
Influence of hydraulic pressure and damage.
As shown in Figure 1, the steam type airheater of the automatic ash removing further includes Electric Actuator 600 and power control cabinet 700,
Power control cabinet 700 is mountable outside shell 100, and power control cabinet 700 sends a signal to Electric Actuator 600, makes Electric Actuator 600
It controls the first filter screen 200 and the second filter screen 300 moves in and out 400 operation of shell and spray equipment.The degree of automation
Height effectively improves working efficiency.Further, which also can control rotation and movement of spray head etc..
To sum up, operator can control Electric Actuator 600 by power control cabinet 700, and Electric Actuator 600 is made to control first
Filter screen 200, the second filter screen 300 and spray equipment 400, to realize the first filter screen 200 and the second filter screen 300 in shell
The automatic spray of the first filter screen 200 and the second filter screen 300 is cleaned in automatic switchover and spray equipment 400 in 100,
High degree of automation effectively improves cleaning efficiency.Also, it should not blowing out progress to the cleaning of filter screen.
Second embodiment
It is different from the first embodiment and is, air inlet of first filter screen 200 relative to the second filter screen 300, with shell 100
Mouth is adjacent.When first filter screen 200 and the second filter screen 300 switch, the second filter screen 300 moves to shell by the second opening
Behind 100 inside, the first filter screen 200 is moved to outside shell 100 by the first opening.When therefore being removed to the first filter screen 200,
It needs first to move to the second filter screen 300 inside shell 100, prevents gas from entering directly into inside shell 100 without filter screen,
And the dust of gas is accumulated inside shell 100.
In addition, the first filter screen 200 and the second filter screen 300 precession or can also screw out shell 100 in rotary manner.Tool
Body, the first filter screen 200 and shell 100 are hinged, and the first filter screen 200 can be rotated by the center of circle of the interface point, Jin Ershi
Existing precession screws out shell 100.
To sum up, the first filter screen 200 and the second filter screen 300 are arranged along the length direction of shell 100, and mutually tight
Neighbour controls Electric Actuator 600 by power control cabinet 700, realizes the automatic switchover of the first filter screen 200 and the second filter screen 300.
Also, the first filter screen 200 and the second filter screen 300 are also moved to 100 inside of shell by the way of rotation or are moved to shell
Outside 100.
Embodiment described above is merely to illustrate the technical idea and feature of the utility model, and its object is to make ability
Technical staff in domain can understand the content of the utility model and implement accordingly, cannot be only practical to limit with the present embodiment
Novel patent uses range, i.e., all according to same changes or modifications made by the revealed spirit of the utility model, still falls in this
In the scope of the patents of utility model.
