Hereinafter, the present invention will be described in detail with reference to the drawings. In addition, although what is shown in figure is an Example of this invention, this invention is not limited to this Example.
FIG. 1 is an explanatory view of a main part of an embodiment of a smoke pipe cleaning structure for a combustion apparatus according to the present invention. 2 is an operation explanatory view of the embodiment shown in FIG. 1, FIGS. 3a to 3g are front views and perspective views of the cleaning means according to FIG. 1, and FIG. 4 is a cleaning action in the smoke pipe by the operation of this embodiment. It is explanatory drawing which shows. As exemplified in these, the present smoke tube cleaning structure is a structure for cleaning the cylindrical smoke tube 80 (FIG. 4) of the combustion apparatus, and the horizontal movement is converted into the vertical movement, and the cleaning means 4 described later is fixed. Rotating element 1, cleaning means 4 consisting of a fixing part 2 fixed to the rotator 1 and a fin part 3 for scraping off deposits on the inner wall of the smoke pipe, and a driving means 5 for driving the rotator 1 to reciprocate horizontally. The fin portion 3 is a spiral belt-like body. In addition, the edge part of the width direction of the fin part 3 shall be formed in the specification which touches the inner wall of the smoke pipe 80 to which this smoke pipe cleaning structure is applied (it is also called "inscribed" and contact | abutting).

  The drive means 5 is composed of at least a connecting rod 51. That is, only the connecting rod 51 may be the driving means 5 itself, while the driving means 5 may be configured by the connecting rod 51 and other elements. In the former case, the connecting rod 51 can be moved horizontally by human power (manual). On the other hand, in the latter case, a driving method using a device (motor or the like) for horizontally moving the connecting rod 51 can be used, and this can be an automatic control method using a control means such as a computer. .

  Further, as shown in FIG. 1, the rotator 1 according to the smoke pipe cleaning structure of the present invention is connected to the connecting rod 51 of the driving means 5 and receives the horizontal drive, and the vertical movement by the horizontal movement of the movable part 11 It is formed with two arms 12 and 12 that move, and a central portion 13 between both arms 12 and 12. And the cleaning means 4 is fixed to each arm part 12 and 12 in the fixing | fixed part. Although the drawing shows that the cleaning means 4 is fixed to the right arm 12, it can of course be fixed to the left arm 12. Basically, the cleaning means 4 can be fixed to both the arm portions 12 and 12, respectively.

The operation of the smoke pipe cleaning structure of the present invention will be described mainly with reference to FIG.
When the driving means 5 is driven, the movable part 11 of the rotator 1 connected to the horizontal movement H of the connecting rod 51 connected to the movable part 11 of the rotator 1 moves horizontally. The horizontal motion of the movable portion 11 is converted into the vertical motion V of the second arm portions 12 and 12 via the rotation R. Both arms 12 and 12 move up and down in opposite directions. Thereby, the cleaning means 4 fixed to each arm part 12 by the fixing part 2 moves up and down in opposite directions, and each fin part 3 moves up and down in the smoke pipe 80. The fin portion 3 that is a spiral belt-like body is moved up and down to scrape and remove deposits (ash and dust) on the inner wall at the edge in the width direction contacting the inner wall of the smoke tube 80. That is, the smoke pipe 80 is cleaned.

  The fin part 3 of the present smoke pipe cleaning structure has a characteristic form as shown in FIGS. That is, it is a form in which the belt-like body is spirally formed in a form twisted around an axis having the longitudinal direction as an axis. Needless to say, the fin portion 3 is formed of a material and specifications that are not deformed by the vertical movement in the state inscribed in the inner wall of the smoke tube and the heat in the smoke tube. Further, it is assumed that one or a plurality of twist units 33 that can be repeatedly formed by the twisting are formed on the fin portion 3. It is desirable that a plurality of twist units 33 are formed instead of only one as shown in FIG.

  The twist unit 33 of the fin portion 3 is inscribed over the entire circumference (360 °) of the inner wall of the smoke pipe 80 with its both-side edges. Therefore, when the cleaning means 4 is moved downward or upward by one twist unit, a scraping action on the entire inner wall of the smoke pipe 80 is performed over the length of one twist unit. By providing n twist units 33, the vertical movement of one twist unit performs a scraping action over the length of n twist units.

  The length of one twist unit is not limited to the illustrated example, and can be designed as appropriate. For example, one twist unit (one pitch) may be 90 to 100 mm. Such a specification is, for example, a specification suitable for cleaning a fire tube of a tire boiler conventionally provided by the applicant. By simply moving the cleaning means 4 up or down by one twist unit (1 pitch) = 90 to 100 mm, the entire smoke tube can be cleaned, that is, ash and dust can be removed, and only a very small operation and operating range are required. No.

  With reference to FIG. 4, the cleaning action in the smoke pipe by the operation of the smoke pipe cleaning structure of this embodiment will be described. If (a) is the standard position (height) of the cleaning means 4, it will be (b) if it is moved up and (d) if it is moved down. The cleaning means 4 may be moved up and down in a cycle of going up from (a) (b), going down from there (c), (d), and going up to return to the standard position (a). . However, if the upper row of (b) is redundant, it is of course possible to drive in a cycle that reciprocates between (a) (or (c), (e)) and (d).

Moreover, the length of the fin part 3 can also be prescribed | regulated like (A) Formula in relation to the twist unit 33. FIG.

(A) Fin section length ≤ Length of applicable smoke tube cleaning object-Twist unit

That is, when the length of the fin portion 33 is set to a length obtained by subtracting one twist unit from the length of the cleaning target portion in the smoke pipe 80, the entire cleaning target region can be processed only by the vertical movement of one twist unit. it can. Although the fin part 33 may be shorter than that, a part of cleaning object site | part will not be cleaned in that case. However, in that case, the range of the vertical movement drive may be made longer than one twist unit. The definition of the above formula (a) is not necessary and is arbitrary, and the range outside the formula does not fall outside the scope of the present invention.

  In short, the rotator 1 is only required to perform the function of converting the vertical movement of the cleaning means 4 through the horizontal drive by the drive means 5, and as long as that is the case, it is not limited to the forms and specifications described so far. .

  Further, the strength is required in the cleaning means 4, particularly in the fixed portion 2. Therefore, it is desirable to change the thicknesses of the fixed portion 2 and the fin portion 3 so that the former is thicker and the latter is thinner. For example, the fixed part 2 is made of steel and the thickness is 25 mm, the fin part 3 is 0.8 to 1.0 mm thick, and the like. However, it is not excluded from the present invention that the fixing portion 2 and the fin portion 3 have the same thickness. Moreover, the fixing | fixed part 2 and the fin part 3 may be integrally formed from the beginning, and may connect and form each member later.

  The smoke pipe cleaning structure of the present invention is set in a state where the fin portion 3 of the cleaning means 4 is inserted into the smoke pipe 80 to be cleaned, and is used by being driven by the driving means 5 outside the smoke pipe 80. As described above, in the case of the manual type, the connecting rod 51 itself is the driving means 5 and is driven horizontally by human power. On the other hand, in the case of an automatic type using a driving device such as a motor, the connecting rod 51 is horizontally driven by the operation of the driving device. Further, as described above, an automatic operation control system using a control means such as a computer can be adopted. Further, the number of times of horizontal driving is one time or two times or more, and is not limited.

  Although not shown in particular, the horizontal movement of the rotator 1 by the driving means 5 is transmitted to one or more other rotators 1, 1,. A structure for cleaning the smoke pipe of the combustion apparatus, in which the cleaning means 4, 4,. In this case, by driving the single drive means 5, the plurality of cleaning means 4, 4,... Can be simultaneously driven up and down, and a plurality of smoke tube cleaning operations can be performed simultaneously.

  In the embodiment of the present invention for cleaning a smoke pipe, the two cleaning means 4 and 4 can be fixed to a single rotor 1, so that the two smoke pipes 80 and 80 are simultaneously cleaned. Can do. Therefore, if there are n rotors 1 that are driven simultaneously, 2n smoke tubes 80 can be processed. When the number of smoke pipes 80 to be simultaneously cleaned is an odd number, the rotator 1 in which only one cleaning means 4 is fixed is generated. The tire boiler provided by the applicant may have a specification having 50 to 200 smoke pipes, but simultaneous driving is possible without any problem even if the number is about 200.

  Further, although not shown, a smoke tube cleaning system using a plurality of smoke tube cleaning structures provided with driving means is also within the scope of the present invention. Each smoke pipe cleaning structure that constitutes the system has a driving means. By connecting the respective rotors, all the cleaning means are simultaneously driven up and down by operating any one of the driving means. It can be configured. The driving means may be any of a manual type, an automatic type using a driving device, or an automatic control type using a control means such as a computer.

  Further, the above-described smoke tube cleaning structure or a tire boiler equipped with a smoke tube cleaning system, an incinerator, a combustion apparatus that generates ash and dust, and a smoke tube with a smoke tube cleaning structure are also within the scope of the present invention. Furthermore, a smoke tube cleaning method performed using the smoke tube cleaning structure or the smoke tube cleaning system of the present invention is also within the scope of the present invention. In the present smoke tube cleaning method, in particular, the smoke tube can be cleaned by operating the cleaning means by one twist unit (one pitch).

  In addition, the cleaning means 4 itself, which is a component such as the smoke tube cleaning structure described above, is also independently within the scope of the present invention. That is, the cleaning means 4 is a tool for cleaning the cylindrical smoke pipe of the combustion apparatus, and is provided with a passive part (fixed part) that receives a drive for moving the inside of the smoke pipe, and an attachment of the inner wall of the smoke pipe. It consists of a fin part that scrapes off the kimono, and the fin part is used as a smoke tube cleaning tool that is a spiral belt-like body, regardless of the presence or absence of drive means and a rotor Is also possible.
