Description

Technical Field

[0001] This application relates to the technical field of sludge treatment, and in particular to a device for forming pellets from sludge incineration furnace slag. Background Art

[0002] Municipal sludge is a by-product of sewage treatment, and its production volume increases with the increase in sewage treatment volume and treatment rate. The harmless and resourceful disposal of municipal sludge has gradually become a hot topic of concern. In China, the proportion of sludge incineration disposal is rising, and the sludge incineration furnace slag generated is also increasing gradually. A large amount of sludge incineration furnace slag belongs to solid waste, which contains heavy metals contained in the sludge itself and must be reasonably disposed of. Since sludge contains a large amount of organic matter and also contains inorganic components such as silicon and aluminum, if the proportion of each component is appropriate, it can be prepared into ceramsite at high temperature and used as lightweight aggregate, cultivation substrate or water treatment filter material for subsequent use.

[0003] Existing ceramsite pelletizing devices generally include a base, a pelletizing disc and a water pipe. The pelletizing disc rotates continuously driven by a power device. During use, the raw materials after sludge incineration are put into the pelletizing disc, and water is added into the pelletizing disc through the water pipe. During the rotation process, the raw materials can be made into spherical particles, and cooperate with subsequent roasting equipment to make ceramsite finished products.

[0004] In view of the above related technologies, during the ceramsite pelletizing process, if the water content is too low, it will be difficult for the raw materials to bond into pellets; if the water content is too high, the ceramsite will be prone to cracking during the firing process; by the way of adding water through the water pipe, the water output at the pipe orifice is large and concentrated, resulting in uneven water addition to the raw materials, thus leading to unsatisfactory pelletizing effect and affecting the pelletizing quality. Utility Model Content

[0032] The following further elaborates on this application in conjunction with the attached drawings. Figures 1-4

[0033] Embodiment 1:

[0034] The embodiment of this application discloses a device for pelletizing sludge incineration furnace slag. Referring to Figure 1 , the pelletizing device includes a base 1, a pelletizing disc 2 and a water spraying system 3. Among them, the pelletizing disc 2 is rotatably arranged on the base 1, and raw materials are put into the pelletizing disc 2 from the opening of the pelletizing disc 2 and are bonded into pellets as the pelletizing disc 2 rotates; the water spraying system 3 includes a water spraying pipe 31 and atomizing nozzles 32. The water spraying pipe 31 is also arranged on the base 1, and one end of the water spraying pipe 31 close to the pelletizing disc 2 is bent and extends to the opening of the pelletizing disc 2. A plurality of atomizing nozzles 32 are installed at intervals on the water spraying pipe 31; the atomizing nozzles 32 can evenly spray water mist into the pelletizing disc 2 continuously, so as to ensure that the raw materials in the pelletizing disc 2 can evenly and fully absorb water and be bonded into pellets.

[0035] In this embodiment, the water spraying pipe 31 preferably extends along the diameter direction of the pelletizing disc 2 outside the opening of the pelletizing disc 2, and the atomizing nozzles 32 are evenly arranged along the vertical direction; in other embodiments, the part of the water spraying pipe 31 extending to the opening of the pelletizing disc 2 can also be set into other shapes such as circular, rectangular, triangular, etc., to further ensure the evenness when the water mist is sprayed into the pelletizing disc 2.

[0036] Referring to Figure 1 , further, in this embodiment, the water spraying system 3 further includes a water storage tank 33, a water pump 34 and a water conveying hose 35. Among them, the water storage tank 33 is used to store the required water source, the water pump 34 is installed in the water storage tank 33 and is responsible for pumping the water in the water storage tank 33 to the water spraying pipe 31. The water conveying hose 35 is used to connect the water pump 34 and the water spraying pipe 31 to ensure that the water can be smoothly conveyed. In this way, the device can realize automatic water supply, thereby improving production efficiency.

[0037] Referring to Figure 1 ​, in an optional embodiment, the water spraying system 3 may further include a water pressure regulating valve 36 and a water pressure gauge 37. The water delivery hose 35 is connected to the water inlet end of the water pressure regulating valve 36, and the water spraying pipe 31 is connected to the water outlet end of the water pressure regulating valve 36, so as to be able to precisely control the water spraying pressure. The water pressure gauge 37 is arranged on the water spraying pipe 31 for real-time monitoring and displaying the current water pressure condition, helping the operator to timely understand the working state of the water spraying system 3 and make necessary adjustments.

[0038] Refer to Figure 1 and Figure 2 , in this embodiment, the base 1 includes a connecting plate 11, a hydraulic cylinder 12 and a support 13. Specifically, the connecting plate 11 is the main supporting component, and both the ball forming plate 2 and the water spraying pipe 31 are arranged on the connecting plate 11. The hydraulic cylinder 12 and the support 13 are both arranged on the ground to support the connecting plate 11. The end of the telescopic shaft of the hydraulic cylinder 12 is hinged to the lower surface of the connecting plate 11, and the upper end of the support 13 is hinged to the lower surface of the connecting plate 11. Thus, by changing the length of the telescopic shaft of the hydraulic cylinder 12, the angle of the connecting plate 11 and the ball forming plate 2 can be finely adjusted; at the same time, in the water spraying system 3, the arrangement of the water delivery hose 35 enables the water spraying system 3 to also adapt to the rotational change of the connecting plate 11.

[0039] Refer to Figure 1 and Figure 2 , in this embodiment, a power component 4 and a rotating shaft 5 are further arranged on the connecting plate 11. The power component 4 is a driving motor. In other embodiments, the power component 4 may also include a worm gear and a worm to increase the stability during use; the driving motor is fixed to the upper surface of the connecting plate 11 by means of bolts, etc. The output end of the driving motor is connected to the rotating shaft 5, and the other end of the rotating shaft 5 is connected to the ball forming plate 2. Thus, starting the motor can drive the ball forming plate 2 to rotate.

[0040] Furthermore, a coupling 6 is arranged between the output end of the driving motor and the device to achieve overload protection for the entire ball forming device. A strengthening seat may be arranged on the connecting plate 11. The rotating shaft 5 passes through the strengthening seat and is rotatably connected through a bearing, thereby improving the stability of the ball forming device during use.

[0041] The implementation principle of a ball forming device for sludge incineration furnace slag ceramsite in an embodiment of the present application is as follows: during use, first pour the raw materials into the ball forming plate 2, then start the driving motor to drive the rotating shaft 5 to rotate and drive the ball forming plate 2 to rotate. At the same time, the water pump 34 sends water to the water spraying pipe 31, and adds water to the raw materials in the ball forming plate 2 through the atomizing nozzle 32, so as to ensure that the water is evenly and moderately added to the raw materials during the ball forming process.

[0042] Embodiment 2:

[0043] The difference between this embodiment and Embodiment 1 is that in order to further improve the forming quality, an impact device 7 is added; specifically, refer toFigure 3 and Figure 4 In this embodiment, further optionally, the ball forming device further includes an impact device 7 for knocking on the outer side wall of the ball forming disk 2. Through the impact device 7, part of the raw materials adhered to the inner side wall of the ball forming disk 2 can be dropped, improving the utilization rate of the raw materials and simultaneously improving the ball forming quality. The impact device 7 includes a control rod 71 rotatably arranged on the outer side wall of the ball forming disk 2, an impact head 72 fixed on the control rod 71, an elastic member 73 for driving the impact head 72 to knock on the outer side wall of the ball forming disk 2, and a guiding block 74 for driving the impact head 72 away from the side wall of the ball forming disk 2.

[0044] Specifically, the control rod 71 can be a rectangular rod. A hinge seat is fixed on the outer side wall of the ball forming disk 2, and a pin shaft on the hinge seat passes through the middle part of the control rod 71, so that the control rod 71 can be rotatably arranged on the outer wall of the ball forming disk 2. With the hinge seat as the center, the impact head 72 is located at one end of the control rod 71 away from the connecting plate 11, and the guiding block 74 is arranged on the connecting plate 11. When the ball forming disk 2 is transferred past the position where the guiding block 74 is located, one end of the control rod 71 close to the connecting plate 11 can abut against the guiding block 74.

[0045] The upper surface of the guiding block 74 is provided with a guiding surface, and the guiding surface is inclined downward toward the side of the ball forming disk 2. When the control rod 71 abuts against the guiding surface, the control rod 71 can rotate along the guiding surface toward the side close to the ball forming disk 2, and the other end of the control rod 71 rotates toward the side away from the side wall of the ball forming disk 2, driving the impact head 72 away from the side wall of the ball forming disk 2. When the control rod 71 rotates away from the guiding block 74 as the ball forming disk 2 rotates, under the elastic force of the elastic member 73, the impact head 72 turns back to the outer side wall of the ball forming disk 2 to form an impact, so that the raw materials adhered to the inner side wall of the ball forming disk 2 can be knocked down by vibration. The control rod 71 and the impact head 72 can be arranged at intervals along the outer circumference of the ball forming disk 2 to improve the knocking-down effect.

[0046] Referring to Figure 3 and Figure 4 In this embodiment, the elastic member 73 is a spring. The spring is arranged between the outer side wall of the ball forming disk 2 and the control rod 71 and is located at one end of the control rod 71 close to the impact head 72. When the impact head 72 abuts against the outer side wall of the ball forming disk 2, the spring is in a stretched state. In other embodiments, the spring can also be a rubber belt, and the rubber belt is sleeved over the control rod 71 in a U shape, so as to also drive the impact head 72 to abut tightly against the outer side wall of the ball forming disk 2.

[0047] The implementation principle of a pelletizing device for sludge incineration furnace slag in an embodiment of this application is as follows: during the rotation of the pelletizing disc 2, when the control rod 71 rotates with the pelletizing disc 2 and passes through the guiding block 74, it can drive the impact head 72 away from the pelletizing disc 2; after passing through the guiding block 74, under the action of the spring, it can impact the outer wall of the pelletizing disc 2 again, knocking off the raw materials that may adhere to the inner wall of the pelletizing disc 2, further ensuring the pelletizing effect.

[0048] The above are all the preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
