Sludge drying system

The present invention relates to a drying treatment system, and more particularly to a sludge drying treatment system.

Referring to FIGS. 1 and 2 , a sludge drying device 1 includes a mixing drum 11 , a heating and stirring unit 12 , a casing member 13 , an air extracting unit 14 , and a driving unit 15 . The mixing drum 11 includes a barrel wall 111 defining an agitation space 110 around an axis L, and an inlet port 112 and a discharge joint 113 spaced apart from the barrel wall 111 and communicating with the agitation space. The heating and agitating unit 12 includes a mandrel 121 rotatably disposed along the axis L and having an axial through hole 120, and a plurality of pairs extending radially outward from the mandrel 121 and along the axis The agitating plates 122 spaced apart from each other in the agitation space 110, and a hot gas pipe 123 penetrating the agitating plates 122 and communicating with the axial through holes 120 of the mandrel 121. The outer casing member 13 is disposed on the outer circumferential surface of the agitating drum 11 and cooperates with the agitating drum 11 to define a plurality of heating spaces 130 located therebetween. The air extraction unit 14 communicates with the agitation space 110. The driving unit 15 is connected to one end of the mandrel 121 for driving the heating and stirring unit 12 to rotate. The axial through hole 120 of the mandrel 121 is connected to the heating space 130 by a pipeline unit 16 connected to a heating unit 17.

When the sludge drying device 1 performs sludge drying, the sludge which can be dried once by the sludge drying device 1 is firstly fed into the agitation space 110 from the inlet port 112, and then the heating is started. The unit 17 and a heat medium are conveyed into the heating space 130, the axial through hole 120 and the heating pipe 123 via the pipeline unit 16, so that the stirring space 110 is heated by the inside and outside of the mixing drum 11, and then the driving is started. The unit 15 drives the heating and agitating unit 12 to rotate, and the agitating plates 122 are linked to agitate the sludge, and the pumping unit 14 is turned on. During the sludge agitation process, the sludge absorbs the heat of the heat medium to evaporate the water content. The evaporated water is further withdrawn from the agitation space 110 via the pumping unit 14, and after the sludge is dried to a certain humidity or less over a period of time, the dried sludge can be removed through the discharge joint 123 for subsequent processing.

However, the sludge drying device 1 described above can dry the sludge, but has the following disadvantages in use:

1. Each pair of stirring plates 122 rotates the agitated sludge at a fixed point, and the effect of pushing the sludge in the axial direction is limited, so that the sludge is easily accumulated in two pairs of adjacent stirring plates 122 to form a large volume of sludge. However, the drying speed of the large-volume sludge mass is obviously slower than that of the dispersed sludge, thus causing the drying efficiency of the sludge drying device 1 to be low. In addition, the un-dispersed sludge mass gradually becomes dry and is easily formed into a wet inner sludge block. However, the agitating plates 122 can have a limited effect of stirring and dispersing the sludge hard block, thereby causing the same batch of drying treatment. There is also a sludge lumps with high humidity in the sludge.

Second, because the mixing drum 11 is large in volume, the heating stirring single The agitating plates 122 of the element 12 also need a sufficient length to effectively agitate the sludge, thereby increasing the rotational inertia of the heating agitating unit 12 as a whole, so that the driving unit 15 requires a large power to drive the heating agitating unit 12 to rotate. Thereby increasing energy consumption. In addition, the large volume of the mixing drum 11 also causes the inner wall surface of the barrel wall 111 heated by the heated medium to become high, and the heat radiation distance for heating the stirring space 110 becomes large, which is liable to cause thermal energy loss. Therefore, it is necessary to accelerate the circulation of the heat medium to maintain the radiation to The heat energy in the agitation space 110 is unbalanced, thereby increasing energy consumption.

3. The sludge drying device 1 is configured to batch-deliver the sludge into the agitation space 110 of the agitating drum 11 for drying treatment, and then dry the sludge to be removed from the agitation space 110, thus requiring additional manpower. Each batch of the sludge to be dried is fed into and out of the agitation space 110 of the agitating drum 11.

Therefore, the object of the present invention is to provide a sludge drying treatment system which is energy efficient and has high drying efficiency and can continuously treat sludge.

Therefore, the novel sludge drying treatment system comprises at least one pipeline type sludge drying device, a sludge automatic quantitative feeding device, a dry sludge receiving device, a driving device, a heating device, and an air extracting device.

1. The driving device 6 continuously drives the spindle 521 of the screw conveying unit 52 to rotate the spiral long plate 522, so that the sludge fed into the storage space 511 of the drum 51 can be automatically and continuously. The material is discharged outward into the agitation space 2111 of the pipeline type sludge drying device 2.

2. The long diameter section 5221, the tapered section 5223 and the short diameter section 5222 of the spiral long plate 522 of each screw conveying unit 52 sequentially push the sludge in the storage space 511 through the discharge passage 5231. Discharged outwardly, and the spiral side of the short diameter section 5222 is adjacent to the discharge joint 523 The inner surface is spatially arranged to fix the amount of sludge pushed into the agitation space 2111 per minute.

3. Adjusting and controlling the number of the screw conveying units 52 driven by the driving device 6, thereby adjusting the amount of sludge conveyed into the stirring space 2111 to match the stirring unit 22 of the pipeline type drying device 2 to push and push The speed of the sludge allows the line-type sludge drying device 2 to perform the sludge drying operation automatically and continuously and more efficiently.

4. The rotation of the mandrel 531 of the stirring unit 53 drives the stirring members 532 to perform circular motion, and the sludge accumulated above and below is loosened and moved downward to the bottom end of the storage space 511. The sludge fed into the storage space 511 can be continuously and completely pushed out by the screw conveying units 52 into the agitation space 2111 of the pipeline type sludge drying device 2.

5. When the stirring unit 22 rotates, the spiral pushing and cutting long plate 2221 cuts and divides the sludge roll, and pushes the broken sludge axially toward the discharging joint 2132, and the stirring column 2222 The sludge is pulverized and dispersed according to the circular motion, and the scraper 2223 scrapes the scattered sludge on the inner wall surface of the inner wall 2112 with high temperature for direct heating and then scraping, thereby stirring The unit 22 can effectively agitate the sludge to avoid agglomeration, thereby accelerating the drying speed of the sludge.

6. Since the pipe diameter of the pipe member 211 is much smaller than the barrel diameter of the conventional mixing drum, the heat radiation distance between the inner wall surface of the inner pipe wall 2112 and the sludge which is high after heating is shorter than that of the conventional mixing drum, and the dirt can be contaminated. The mud receives the heat more quickly and becomes a high temperature state, so that the moisture content thereof evaporates rapidly, and the heat radiation distance The shorter, the less heat energy is transferred, which effectively reduces energy consumption.

7. Since the pipe diameter of the pipe member 211 is small, the outer diameter of the agitation group 222 disposed therein is also relatively small, so the moment of inertia of the agitation group 222 is relatively small, so that the driving device 6 requires only a small amount of power. The agitation unit 22 is driven to rotate to achieve a sludge tumbling effect, which greatly reduces power demand.

8. The agitation unit 22 can continuously push the sludge fed into the agitation space 2111 by the feed joints 2131, and continuously push the sludge to the discharge joint 2132 to discharge to the dry sludge receiving device 7, so that only The sludge can be continuously supplied to the sludge through the sludge automatic dosing device 5, and the sludge drying operation can be continuously performed automatically, compared with the conventional sludge drying device which can only perform sludge drying treatment in batches. Significant savings in manpower requirements.

IX. Due to the small volume of the pipeline type sludge drying device 2, according to the actual sludge drying capacity, the combination of the two types of pipeline type sludge drying devices 2 in series or in parallel can be used for expansion. Effectively save the additional cost of sludge drying equipment. In addition, the small volume of the pipeline type sludge drying device 2 occupies a small space, which can effectively save the construction cost of accommodating the building.

Referring to Figure 12, a second embodiment of the novel sludge drying treatment system is substantially identical to the first embodiment, except that the dry sludge receiving device 7 further includes a parallel connection group 74, the valve The group 73 has a four-way valve 731 connected between the first and second suction joints 713, 723 and the air extracting device 4, and four connected to the parallel connecting pipe 741 and the feeding joints 711 and 721, respectively. And the discharge joints 712, 722 Shutoff valve 732. The parallel connection group 74 has a parallel connection pipe 741 for connecting the feed joints 711 and 721 of the first and second receiving hoppers 71 and 72 in parallel to the discharge joint 2132 of the most downstream pipeline type sludge drying treatment device 2, And a three-way valve 742 disposed in the parallel connection pipe 741.

The three-way valve 742 can be connected to the discharge joints 2132 of the most downstream pipeline type sludge drying device 2 and the feed joints 711 and 721 of one of the first and second receiving buckets 71 and 72, The dried sludge dried by the line type sludge drying device 2 is discharged into one of the first and second receiving hoppers 71, 72 for temporary storage.

When the dry sludge located in the first and second receiving hoppers 71, 72 is outwardly discharged into a space bag 83 for packaging, the four-way valve 731 is first manipulated to make the first and second receiving hoppers 71, 72. The internal space communicates with the atmosphere to break the negative pressure state, and then the shut-off valve 732 connecting the first and second discharge joints 722 is opened, and the dry sludge in the first and second receiving buckets 71, 72 is lowered. Discharge into the space bag 83, and after the complete discharge, the above-mentioned stop valve 732 is closed, and the four-way valve 731 is operated such that the internal spaces of the first and second receiving hoppers 71, 72 communicate with the air extracting device 4 for pumping. Gas is under negative pressure. The dry sludge in the first and second receiving hoppers 71, 72 can be discharged into the space bag 83 by simply opening the shut-off valve 732 connecting the first and second discharge joints 712, 722. The stop valve 732 is closed immediately after it is completely discharged. Therefore, when the pipeline type sludge drying device 2 discharges outward, the outside air does not enter the stirring space 2111 through the discharge connector 2132 of the most downstream to maintain the stirring space 2111 stable. Negative pressure state.

As can be seen from the above description, the second embodiment can also achieve the same advantages and effects as the first embodiment.

However, the above is only a preferred embodiment of the present invention, and when it is not possible to limit the scope of the present invention, any simple equivalent changes and modifications made in accordance with the scope of the present patent application and the contents of the patent specification are It is still within the scope of this new patent.
