Specific embodiment
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing to this
The specific embodiment of utility model is described in detail.Many details are explained in the following description in order to abundant
Understand the utility model.But the utility model can be implemented with being much different from other way described herein, this field
Technical staff can do similar improvement without prejudice to the utility model connotation, therefore the utility model is not by following public affairs
The limitation for the specific implementation opened.
As shown in the main view for unloading grey anti-block device of the rotatory feeder valve in Fig. 3 and the joint view of left view, it is
Solve the problems, such as the card resistance of the active carbon dust 5 overstock in the end space in the prior art 4 in Fig. 1-2, the utility model
One group of ash-unloading slot mouth 8, ash-unloading slot mouth 8 are devised in the lower part of the end flanges 7 of valve body 1 (valve body 1 is the shell for protecting rotor 2)
For the notch arrangement being obliquely installed, from the figure 3, it may be seen that left view Angular Dimension is a °, depth dimensions Amm, as long as specific size
It can guarantee that the dust-proof dust stratification of active carbon can thoroughly unstow, specifically, its ash-unloading slot mouth 8, which includes one, is provided with hold-carrying
The inclined-plane and opening face positioned at inclined-plane both ends of the lower part of orchid 7, three faces define above-mentioned ash-unloading slot mouth 8, ash-unloading slot mouth 8
Inclined-plane is located at the lower part of end flanges 7, and one of opening face of ash-unloading slot mouth 8 is connected to the lower end of end space 4, ash-unloading slot
Another opening face of mouth 8 is connected to the material outlet of valve body 1；Main view in Fig. 3 is fixed on the basis of end flanges center line
Position and size dimension are B, C, and the rotary valve concrete type as shown in Fig. 3-5 of the application is centering type rotary valve, and in order to make
The not discharge of material shown in influence diagram 4 of ash-unloading slot mouth 8, therefore the Design of length of B and C in Fig. 3 are that unequal and length is closed
Suitable, specific size C > B in short, above-mentioned size is considered as the openings of sizes of rotatory feeder valve, and needs to consider ash-unloading slot mouth
8 ash that unloads does not influence normal material conveying.
It should be noted that as shown in Figure 2-5, which is to connect the both ends of the surface of the cover board 6 and rotor 2 of two sides
Radius (i.e. the half of the both ends of the surface of rotor 2 of intermediate connector, the radius of the flange hole of end flanges 7 and blade-carrying rotor 2
Diameter) length basic size it is equal (according to installation requirement, the installation deviation of very little can be set up and down when actually will be installed, but
It is that its basic size is equal), flange hole constitutes end space 4 at this time, and end flanges 7 are located at the inside of valve body 1, ash-unloading slot
8 inclination of mouth is provided with the lower part of the sealing surface of end flanges 7, and ash-unloading slot mouth 8 is a groove for the active carbon dust 5 that comes down in torrents
Mouthful, it is located at the adjacent bottom portions of the central symmetry axis of end flanges 7, since the cross section of the ash-unloading slot mouth 8 in Fig. 2-5 is one
Right angled triangle, therefore its a ° of inclined angle is less than 90 ° of acute angle, and its depth A also design will not be too long, in order to avoid influence
The fixed function of flange.
As shown in figure 3, ash-unloading slot mouth 8 is designed as the triangular prism that a cross section is right angled triangle, at this time ash-unloading slot mouth 8
Inclined-plane (the namely plane of the bevel edge of right angled triangle) be specifically a lower part for being provided with end flanges 7 a plane；
Or it is further, it is fan-shaped fan-shaped cylindricality that the shape of ash-unloading slot mouth 8, which can be a cross section, at this time ash-unloading slot mouth 8
Inclined-plane be specifically arc surface (being not shown in Fig. 3), certainly, the width of the inclined-plane both ends open of ash-unloading slot mouth 8 is not necessarily
It is set as equal, inclined-plane specifically can be arcwall face, and ash-unloading slot mouth 8 is arc cylindricality at this time.
As illustrated in figures 4-5 (D that Fig. 5 is Fig. 4 to side view), there are the end flanges 7 of ash-unloading slot mouth 8 being assembled with to improve
Afterwards, when active carbon dust 5 enters end space 4 by rotor 2 and 1 gap of valve body, due to being conducive to for ash-unloading slot mouth 8 itself
The structure and size design of ash are unloaded, while being driven plus the revolution of 2 outer end face of rotor, makes the active carbon dust 5 entered can be whole
It is drawn off by gravity from ash-unloading slot mouth 8, to fall at the material outlet of valve body 1, and is discharged to outside rotatory feeder valve, thus
The effective solution deposition problems of dust avoid equipment card resistance bring a series of problems caused by material dust deposits.
It is noted that the material in the rotatory feeder valve of the utility model may not necessarily be active carbon particle 3,
It can be the materials such as other solids or dust.In addition, the both ends of the surface of cover board and rotor carry out stable company using end flanges
Belong to conventional demand although connecing, the technical issues of the utility model above-mentioned found dust card resistance is based on practical
The technical issues of being found in engineering, and the means for solving the technical problem are also by being observed technical problem and being analyzed
The innovative targeted and feasible technological means obtained afterwards, therefore the proposition of the technical problem and solution are not this fields
What technical staff was readily apparent that.And technical effect below can be obtained:
1, the ash-unloading slot mouth structure effective solution that the is obliquely installed fouling phenomenon of tip-clearance；
2, the utility model is small to the improvement of existing device, can save hardware cost；
3, centering type rotary valve equipment is avoided because of motor overload, rotor and shell locking caused by dust stratification, equipment revolution
Structural wear serious situation, effectively reduces the failure rate of equipment, and improves the service life of equipment.
It is noted that be referred to as " being fixed on " another element when element, it can directly on the other element or
There may also be elements placed in the middle by person.When an element is considered as " connection " another element, it can be directly to
Another element may be simultaneously present centering elements.Term as used herein " vertical ", " it is horizontal ", " left side ", "
It is right " and similar statement is for illustrative purposes only, is not meant to be the only embodiment.
Unless otherwise defined, all technical and scientific terms used herein are led with the technology for belonging to the utility model
The normally understood meaning of the technical staff in domain is identical.Terminology used in the description of the utility model herein only be
The purpose of description specific embodiment, it is not intended that in limitation the utility model.Each technical characteristic of embodiment described above
It can be combined arbitrarily, for simplicity of description, not to all possible combination of each technical characteristic in above-described embodiment
It is all described, as long as being all considered to be the model of this specification record however, there is no contradiction in the combination of these technical features
It encloses.
Although being described in conjunction with the accompanying the embodiments of the present invention, those skilled in the art can not departed from
Various modifications and variations are made in the case where the spirit and scope of the utility model, such modifications and variations are each fallen within by appended
Within claim limited range.
