Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0029] Refer to Figure 1 and Figure 2 In this embodiment, a device for sludge drying treatment is disclosed. The treatment device mainly includes a water filtering mechanism 1, a drying mechanism 2, and a heat pump unit 3. Among them, the drying mechanism 2 is located at the lower part of the sludge drying treatment device, and the heat pump unit 3 connected to the drying mechanism 2 through an air duct is installed on one side in the middle of the sludge drying treatment device. Particularly, a plurality of groups of water filtering mechanisms 1 for dewatering wet sludge are arranged side by side above the drying mechanism 2. The plurality of groups of water filtering mechanisms 1 arranged side by side can be arranged in a single row or multiple parallel rows. In this embodiment, a two-row parallel arrangement method is taken as an example for illustration.

[0030] The sludge drying treatment device is supported and carried by a frame 4. The main body of the frame 4 is composed of two "冂"-shaped frames. The sides of the "冂"-shaped frames are fixedly connected by cross bars 41, and the upper part of the "冂"-shaped frames is supported and fixed by horizontal bars 44. An equipment platform 45 is fixedly installed on one side of the frame 4. The equipment platform 45 is located at the front end of the water filtering mechanism 1. One side in the middle of the water filtering mechanism 1 is fixed to the frame 4 by a cross bar 41. The other side bottom of the water filtering mechanism 1 is fixed to the upper part of one side of the bearing frame 42. A plurality of vertical bearing rods 43 are arranged in the middle of the bearing frame 42. The vertical bearing rods 43 are fixedly connected to the horizontal bar 44 at the top of the frame 4. A drainage channel 18 is opened on the bearing frame 42 adjacent to the side of the water filtering mechanism 1. Since the water filtering mechanism 1 is arranged in a two-row parallel arrangement method in this embodiment, drainage channels 18 are opened on both sides of the bearing frame 42.

[0031] like Figure 3 and Figure 4 As shown, a movable sealing plate 17 for supporting the sludge inside the water filtering mechanism 1 is provided at the bottom. One side of the movable sealing plate 17 is mounted on the arc-shaped protrusion on the upper part of the vertical plate 171, and the two ends of the side are rotatably connected with the movable sealing plate 17 through hinge assemblies 172 respectively. The movable sealing plate 17 rotates around the hinge assembly 172 while being supported by the arc-shaped protrusion on the upper part of the vertical plate 171; the two ends of the other side of the movable sealing plate 17 are fixedly provided with hanging ears 173, and the hanging ears 173 are connected to the motor 174 arranged on the frame 4 through a steel wire rope to establish a pulling connection.

[0032] Before the water filter mechanism 1 starts working, the motor 174 is operated to pull up the steel wire rope, driving the movable sealing plate 17 on one side of the hanging ear 173 to rotate upward, until the upper end surface of the movable sealing plate 17 is in contact with the bottom of the water filter mechanism 1, and then the operation stops. It should be noted that when the upper end surface of the movable sealing plate 17 is in contact with the bottom of the water filter mechanism 1, the movable sealing plate 17 and the water filter mechanism 1 are in a sealed state. For example, a rubber pad can be provided at the position where the upper end surface of the movable sealing plate 17 is in contact with the bottom of the water filter mechanism 1 to increase the sealing performance, or other sealing measures can be adopted. When the water filter mechanism 1 completes the sludge water filtering work, the motor 174 is operated again, and the operation direction of this time is opposite to the previous operation direction. The hoisting mechanism of the motor 174 releases the steel wire rope, the hanging ear 173 falls, and the movable sealing plate 17 tilts and rotates downward, so that an open area appears between the movable sealing plate 17 and the lower part of the water filter mechanism 1, and the sludge in the water filter mechanism 1 slides down to the drying mechanism 2 below, which is convenient for the next step of drying and dehumidification.

[0033] It is worth mentioning that in this embodiment, Figure 5 and Figure 6 As shown, the water filter mechanism 1 includes an expansion body 11 for squeezing wet sludge and a filter body 12 for blocking the sludge through which water molecules pass. The expansion body 11 is located on both sides of the water filter mechanism 1, and the filter body 12 is arranged between the expansion body 11. The expansion body 11 and the filter body 12 are sealed and fixed by a frame 13. The upper part of the water filter mechanism 1 is a cover plate 16 with a wet sludge inlet 15, and the lower part is a movable sealing plate 17. It should be noted here that: two or one filter body 12 can be set, which is set according to the production demand. In this embodiment, one is set as an example for explanation. When only one filter body 12 is set, the other side corresponding to the filter body 12 can be sealed with a sealing plate. When the water in the wet sludge is subjected to the squeezing force generated by the expansion of the expansion body 11, the squeezed water flows out of the water filter mechanism 1 only through the filter body 12. In order to allow the expansion area generated by the expansion body 11 to fully squeeze the wet sludge in the water filtering mechanism 1, a protrusion may be provided inside the sealing plate to fill the extrusion gap generated at the sealing plate when the expansion bodies 11 on both sides expand, thereby improving the extrusion drainage efficiency.

[0034] In order to conveniently collect and process the water discharged from the water filtering mechanism 1, a drainage channel 18 is opened on the supporting frame 42 adjacent to the side of the water filtering mechanism 1 as mentioned above, that is, a drainage channel 18 is also provided at the lower part of the water filtering mechanism 1 located on one side of the filter body 12, and the end of the drainage channel 18 is connected to the drainage pipe 19, and the drainage pipe 19 extends into the collection equipment for further purification.

[0035] The expansion body 11 is sealed and fixed on both sides of the internal gap of the frame 13. The gap is used to fix the structure of the expansion body 11 on one hand, and to facilitate the setting of the expansion medium entry channel on the other hand, which serves as a medium for the expansion medium to enter the expansion body 11. The upper part of the frame 13 is provided with a medium pipeline opening 14 for the expansion medium to enter the internal gap of the frame 13 and the expansion body 11. The top of the two frames 13 is fixedly provided with a cover plate 16. The lower part of the two frames 13 is connected by a fixing member 131. The four sides of the filter body 12 are respectively sealed and installed on the side of the frame 13, the upper end face of the fixing member 131 and the lower end face of the cover plate 16. The sealing plate provided on the other side corresponding to the filter body 12 referred to above is the one that is sealed and installed on the inner side of the frame 13.

[0036] A wet sludge inlet 15 is provided in the middle of the cover plate 16, a one-way valve is provided on the wet sludge inlet 15, and the wet sludge inlet 15 is connected to the wet sludge plunger pump pipeline through the main input pipe 151. The one-way valve ensures that the wet sludge can only enter the water filter mechanism 1 through the wet sludge inlet 15, and cannot flow back to the main input pipe 151 through the wet sludge inlet 15.

[0037] A stop valve for controlling the passage is arranged on the medium pipeline port 14, and the medium pipeline port 14 is connected with the medium generator 142 through the medium delivery pipe 141. The medium generated by the medium generator 142 continuously enters the expansion body 11 through the pipeline and the medium pipeline port 14, and the accumulation of the medium in the expansion body 11 causes the expansion body 11 to expand.

[0038] In order to ensure the drying effect of the device on the wet sludge, most of the water contained in the wet sludge is squeezed out after the water filter mechanism 1 treats the wet sludge. In order to achieve a higher application range for the drying treatment of the device and to make the device meet the moisture content requirements of the drying treatment as comprehensively as possible, the drying mechanism 2 and the heat pump unit 3 in this embodiment are used to further dry the sludge falling from the water filter mechanism 1. It should be pointed out that in this device, a moisture content sensor is set in the water filter mechanism 1 to detect the change in moisture content of the sludge.

[0039] like Figure 7 and Figure 8As shown in the figure, the drying mechanism 2 includes a rotating mesh belt 21 and a hopper box 22. The hopper box 22 is arranged below the water filtering mechanism 1. The rotating mesh belt 21 is installed at the lower end of the hopper box 22. An outlet 23 is arranged at one end of the hopper box 22, and an air return port 24 is arranged at the other end. The air return port 24 is communicated with the exchanger of the heat pump unit 3 through an air duct. Hot air outlets 25 for conveying high-temperature drying are arranged on both sides of the lower part of the hopper box 22. The hot air outlets 25 are connected with the output end of the heat pump unit 3 through an air duct. The lower part of the hopper box 22 is provided with a "U"-shaped partition board. For the convenience of cleaning waste, the bottom partition board of the "U"-shaped partition board can be of a pull-out movable type. When the sludge fragments fall and accumulate to a certain extent, the bottom partition board is pulled out to clean the sludge fragments.

[0040] Since the rotating mesh belt 21 is driven to rotate by a transmission shaft, from the cross-sectional view of the structure, the transmission shaft divides the rotating mesh belt 21 into upper and lower parts. In this embodiment, the upper and lower parts of the rotating mesh belt 21 of the transmission shaft can be arranged above and below the bottom partition board of the "U"-shaped partition board. The hot air outlets 25 are arranged on both sides of the "U"-shaped partition board. The air outlets of the hot air outlets 25 face the inside of the hopper box 22, and the drying hot air is blown out from the bottom. Due to the flow direction limitation of the "U"-shaped partition board, the drying hot air is promoted to pass through the rotating mesh belt 21 and dry the sludge upward to form a convection. Finally, the wet air returns to the heat pump unit 3 through the air return port 24 and the air duct. The heat pump unit 3 dehumidifies and heats the wet air before it can be used to dry the sludge again. Among them, the dehumidification uses a cooling tower and a heat exchanger to exchange with the wet air, cool the wet air into condensed water and discharge it, and the wet air becomes dry air. In the field of sludge drying treatment, the use of air dehumidification and waste heat recovery is already a mature technology, and no detailed description will be made in this embodiment.

[0041] After the water filtering mechanism 1 processes the wet sludge, the movable sealing plate 17 rotates, and the plate surface inclines downward. The sludge in the water filtering mechanism 1 slides down onto the rotating mesh belt 21 of the lower drying mechanism 2 under the action of its own gravity. At this time, the drying hot air generated by the heat pump unit 3 is blown into the hopper box 22 through the air duct and the hot air outlet 25 to further dehumidify and dry the sludge. The processed sludge is discharged from the outlet 23 of the device. In order to facilitate observing and monitoring the moisture content of the sludge, a moisture content sensor is also arranged in the hopper box 22. It should be noted that the moisture content sensor in this embodiment is a conventional detection instrument, and those skilled in the art can install it at the required position according to the use needs. This solution will not be described in detail, but it does not affect the normal implementation of this solution.

[0042] In this embodiment, the medium generator 142 and the heat pump unit 3 are both arranged on the equipment platform 45. As Figure 1 and Fig. 9As shown, in order to protect the operating environment of the device, a protective plate 46 is provided on the outside of the frame 4, and the protective plate 46 divides the sludge drying treatment device into an upper water filtration bin 461, a lower drying bin 462, and an equipment bin 463 where the equipment platform 45 is located. Dividing the device into multiple functional areas is beneficial to the management and use of the device, and an independent operating environment is established for each functional area to ensure the stability of the operation of each functional area.

[0043] It is particularly noted that the inside of the expansion body 11 expands continuously with the increase of the volume of the medium filled therein, and there is a maximum expansion value. Here, when in use, the medium filled into the expansion body 11 should be lower than the limit requirement of the expansion value to ensure the safety of the expansion body 11. The expansion body 11 is made of a material that is retractable and has sealing properties, and the filter body 12 is a filter screen that has the function of filtering water and has a certain strength. For example, in this embodiment, the expansion body 11 can be an airbag made of rubber, and the filter body 12 can be a filter screen made of polypropylene and steel wire mesh. In addition, the medium generator 142 is a device for generating filling medium, which can be a gas generating device or a liquid generating device, that is, filling gas or liquid into the expansion body 11. In this embodiment, the medium generator 142 composed of an air compressor and an air compression tank is preferably used. It should be noted that when liquid is selected as the expansion medium, the medium generator 142 can be composed of a water storage tank and a water pump. At this time, the pipeline for conveying liquid needs to be inserted into the bottom of the water filter mechanism 1, so that it is convenient for the expansion body 11 to be completely drawn out of the expansion body 11 when it needs to be contracted.

[0044] Working principle: When the utility model is in use, a plunger pump is used to transport the wet sludge to be treated through the sludge conveying pipe into the main input pipe 151, and then transported along the branch pipes on the main input pipe 151, and finally transported to each water filter mechanism 1 through the wet sludge inlet 15. When a certain amount of wet sludge is injected into the water filter mechanism 1, the plunger pump is stopped. The medium generator 142 is started to fill the medium into the expansion body 11 of the water filter mechanism 1 through the medium conveying pipe 141 and the medium pipeline port 14. The continuous accumulation of the medium in the expansion body 11 causes the expansion body 11 to expand, thereby squeezing the wet sludge in the water filter mechanism 1, squeezing out the moisture in the wet sludge, and then filtering through the filter body 12 and then discharging from the water filter mechanism 1. The squeezed moisture flows downward along the filter body 12 to the drainage channel 18, and the moisture is finally discharged to the collection device through the drainage pipe 19 connected at the end. Reference Figure 3 The hoisting mechanism of the motor 174 releases the wire rope, the hanging ear 173 falls, and the movable sealing plate 17 tilts downward, so that the sludge in the water filtering mechanism 1 slides down to the rotating mesh belt 21 of the drying mechanism 2 below. At this time, the dry hot air generated by the heat pump unit 3 is blown out to the hopper box 22 through the air duct and the hot air outlet 25, and the sludge is further dehumidified and dried, and finally the sludge drying operation is completed. The treated sludge is discharged from the device through the discharge port 23.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
