【発明が解決しようとする課題】
しかしながら、此種従来のスラッジ乾燥装置は、上記特許文献にも見られるようにいずれも構造が頗る複雑なため、価格が高く、また、製造組立て、稼働における調整作業等に多大な労力が要るという不具合があり、専らスラッジ処理工場のような専用工場のみで使用されるだけで、鍍金工場等のような一般の工場等で手軽に使用できない問題があった。
【0005】
従って本発明の技術的課題は、全体の構成が比較的簡単で価格が安く、また、製造組立て、稼働における調整作業が簡単で、各種の工場において手軽に使用することができるように工夫したスラッジ乾燥装置を提供することである。
【0006】
【課題を解決するための手段】
上記の技術的課題を解決するために本発明で講じた手段は以下の如くである。
【0007】
(1) 前記請求項1に記載の如く、水分を多く含んだスラッジを、熱ガス発生装置の高温ガスにより加熱して乾燥処理するように構成したスラッジ乾燥装置であって、少くとも上面を開放し、底板を開閉自在に構成した乾燥槽の内部に、多数本の回転軸を横方向に間隔をあけて横一列に並設し、これ等各回転軸には、多数の通気穴を穿設したパンチング板を、隣接するもの同士が接触しないように、また、夫々が同一平面を構成できるように近接状態に取付けると共に、これ等各回転軸を連動回転自在と成し、且つ、上記同一平面を構成する各パンチング板の上面側乾燥槽の内部を、前記スラッジの収容室と成し、上記各パンチング板の底面側乾燥槽の内部を、上記高温ガスが吹込まれる加熱室と成したことを特徴とする。
【0008】
(2) 前記請求項2に記載の如く、前記請求項1に記載のスラッジ乾燥装置において、前記乾燥槽の外側部に突出した各回転軸の先端部にウオームホイールを取付ける一方、手動又はモータによって回転できるように上記乾燥槽の外側部に沿わせて架設した回転操作軸に、上記各回転軸のウオームホイールに噛合する複数のウオームギヤを取付けたことを特徴とする。
【0009】
(3) 前記請求項3に記載の如く、前記請求項1と2に記載のスラッジ乾燥装置において、前記乾燥槽に移動用の車輪を取付ける一方、手動又はモータによって作動して上記乾燥槽の底板を開閉することができるウインチ装置を、乾燥槽の外側部に設けたことを特徴とする。
【0010】
上記(1)〜(3)で述べたスラッジ乾燥装置によれば、各回転軸を手動又はモータで連動回転して、各パンチング板が同一平面を構成するように水平状態にセットした後、これ等パンチング板の上面側収容室に水分を多く含んだスラッジを積込み、その後、各パンチング板の下側加熱室に熱ガス発生装置の高温ガスを吹込めば、その高温ガスが各パンチング板の通気穴を通って上側に積込まれたスラッジに接触して加熱するため、この高温ガスの加熱によって収容室内のスラッジを均一に乾燥して減量することができる。
【0011】
上記の乾燥が済んだら、上記熱ガス発生装置による高温ガスの噴射を止め、各回転軸を手動又はモータで連動回転して、乾燥を終えたスラッジを下側の加熱室に落し込むと共に、乾燥槽の底板をその時、又は、所定の移動先(廃棄場等)に於いて手動又はモータで開くことにより、乾燥を終えて重量を約1/3、容積を約2/5に夫々減量されたスラッジを、乾燥槽の外に排出処理することを可能にする。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a sludge drying apparatus for subjecting various types of sludge containing a large amount of water, such as plating sludge and sludge sludge, to heat drying.
[0002]
[Prior art]
Conventional sludge drying equipment that uses a high-temperature gas generated by a hot gas generator to dry sludge containing a large amount of water by non-contact indirect heating is a conventional sludge drying apparatus that has a triple internal and external sludge structure and a rotating inside. It is put into the inside of a drying chamber having a lift scraper, where it is dried by receiving radiation and heat transfer from the inner and outer surfaces, and is processed into a dry granulated solid with low moisture while being stirred and granulated by the swivel-type lift scraper. It is designed to be carried out from the drying room outlet. (See, for example, Patent Documents 1 and 2)
[0003]
[Patent Document 1]
JP-A-8-42969 [Patent Document 2]
JP-A-8-61852
[Problems to be solved by the invention]
However, this type of conventional sludge drying apparatus has a very complicated structure as seen in the above-mentioned patent documents, so that it is expensive, and also requires a large amount of labor for manufacturing, assembling, adjusting work in operation, and the like. There is a problem that it is used only in a dedicated factory such as a sludge processing factory and cannot be easily used in a general factory such as a plating factory.
[0005]
Therefore, a technical problem of the present invention is that the sludge has a relatively simple structure, is inexpensive, has simple adjustment work in manufacturing and assembling and operation, and can be easily used in various factories. It is to provide a drying device.
[0006]
[Means for Solving the Problems]
Means taken by the present invention to solve the above technical problems are as follows.
[0007]
(1) A sludge drying apparatus configured to heat and dry a sludge containing a large amount of water with a high-temperature gas from a hot gas generator as described in claim 1, wherein at least an upper surface is opened. A number of rotating shafts are arranged side by side in a horizontal line at intervals in the horizontal direction inside a drying tank with a bottom plate that can be opened and closed, and a number of ventilation holes are drilled in each of these rotating shafts. The punched plates are mounted close to each other so that adjacent ones do not come into contact with each other, and each can form the same plane. The inside of the upper side drying tank of each punching plate constituting the above constitutes a storage chamber for the sludge, and the inside of the bottom side drying tank of the above punching plate constitutes a heating chamber into which the high-temperature gas is blown. It is characterized by.
[0008]
(2) As described in the second aspect, in the sludge drying apparatus according to the first aspect, a worm wheel is attached to a tip portion of each rotating shaft protruding to an outer portion of the drying tank, and is manually or by a motor. A plurality of worm gears meshing with worm wheels of each of the rotating shafts are attached to a rotating operation shaft erected along the outside of the drying tank so as to be rotatable.
[0009]
(3) As set forth in claim 3, in the sludge drying apparatus according to any one of claims 1 and 2, while a moving wheel is mounted on the drying tank, the bottom plate of the drying tank is operated manually or by a motor. A winch device that can be opened and closed is provided outside the drying tank.
[0010]
According to the sludge drying device described in the above (1) to (3), each rotating shaft is rotated manually or by a motor in an interlocking manner, and each punching plate is set in a horizontal state so as to form the same plane. A sludge containing a large amount of water is loaded into the upper chamber on the upper side of the perforated plates, and then the hot gas from the hot gas generator is blown into the lower heating chamber on each perforated plate. Since the sludge loaded above through the hole is brought into contact with and heated, the sludge in the storage chamber can be uniformly dried and reduced in weight by the heating of the high-temperature gas.
[0011]
After the above drying, the injection of high temperature gas by the above hot gas generator is stopped, and each rotating shaft is rotated manually or by a motor to rotate the dried sludge into the lower heating chamber while drying. By drying the bottom plate of the tank at that time or at a predetermined destination (disposal site, etc.) manually or with a motor, the weight was reduced to about 1/3 and the volume to about 2/5 after drying. The sludge can be discharged out of the drying tank.
[0012]

In FIGS. 1 to 5, reference numerals 6 denote the same plane when the respective rotating shafts 4 are rotated at a predetermined angle as shown in FIG. Each of these punching plates 6 is mounted so as to be extremely close to each other so that adjacent ones do not contact each other. Numerals 6P are ventilation holes formed in the surface of each punching plate 6. When the punching plates 6 are horizontally shown as shown in FIGS. 2 and 3, respectively, the inside of the drying tank 1 on the upper surface side of each of the punching plates 6 accommodates the sludge SR. The interior of the drying tank 1 below the punching plates 6 is a heating chamber 1D into which a high-temperature gas for drying is blown.
[0015]
Further, in the drawing, HF is a hot gas generator (gas burner and circulation fan) capable of injecting a high-temperature gas into the heating chamber 1D from a blowing port 1E provided on the outer surface of the drying tank 1, and 7 is the drying tank. Reference numeral 7 denotes a rotating handle provided on the rotary operating shaft 7, reference numeral 7H denotes a bearing, and reference numeral 7K denotes a worm gear attached to the rotary operating shaft 7.

Further, a drawer for receiving the dried sludge may be provided in the heating chamber 1D, and the treated sludge may be discharged in a state required for the drawer.
[0018]
Since the sludge drying apparatus according to the present invention has the configuration as described above, the left and right bottom plates 1Z, 1Z are closed, and each of the rotating shafts 4 is rotated to turn all the punching plates 6 as shown in FIGS. After that, the sludge SR containing a large amount of water is loaded into the upper side accommodation room 1R of the punching plates 6, and then the hot gas generator HF is operated to heat the high-temperature gas. When the hot gas is blown into the chamber 1D, the blown high-temperature gas passes through the sludge layer loaded through the ventilation holes 6P of the punching plates 6, and the heat contained in the sludge SR causes moisture contained in the sludge SR. Is vaporized and evaporated, and the sludge SR can be dried.
[0019]
