Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a municipal sludge ceramsite forming device. Background Art

[0002] Municipal sludge is a waste generated during sewage treatment, accounting for about 0.3%-0.5% of the treated water. If a large amount of untreated sludge is not properly disposed, it will cause more serious secondary pollution to the environment. When making sludge into ceramsite, a municipal sludge ceramsite forming device is needed.

[0003] The molding devices in the prior art usually only use a single drying method when making ceramsite from sludge. Since the water content in the sludge is relatively high, the water contained in the sludge needs to be removed before making the ceramsite from the sludge. However, the molding devices in the prior art usually dry the sludge by a heating component when dewatering the sludge. Although the heating component can also effectively dry the sludge, the drying process is relatively time-consuming and labor-intensive. If the sludge is not centrifugally dewatered before being dried, the water removal efficiency of the sludge will be relatively low, and the effect of the sludge after drying may not be ideal, thereby affecting the ceramsite molding effect of the sludge.

[0004] Compared with the Chinese patent with publication number CN219837941U, the utility model discloses a device for preparing lightweight ceramsite from municipal sludge, which belongs to the field of sludge treatment technology; it includes a box, a pressing plate, a cylinder, a motor and a collection box, the top of the box is fixedly provided with a cylinder, the inside of the box is provided with a pressing plate, an extrusion plate and a cutting plate from top to bottom, the extrusion plate is fixedly connected to the inner wall of the box, and the piston rod of the cylinder is fixedly connected to the pressing plate; the lower end of the cutting plate is provided with a motor fixedly connected to the lower surface of the box, and the output end of the motor is fixedly connected to the middle of the bottom end of the cutting plate through a transmission shaft. The utility model makes the sludge into small pieces through the cooperation of the extrusion plate and the pressing plate, and the small pieces of sludge are dried by the heating component and fall into the discharge bin, so that the sludge packed with ceramsite is made and collected, and the cutting plate fits the lower end of the extrusion plate to ensure the forming and cutting of the ceramsite, which is convenient to use.

[0005] The above scheme can very conveniently process the sludge into expanded clay, but it still uses a single heating component when drying the sludge. The above scheme still does not perform centrifugal dewatering on the sludge before drying the sludge, which not only leads to low dewatering efficiency of the sludge, but also fails to guarantee the drying efficiency of the sludge, and fails to solve the problems raised in the above background technology.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1 - Figure 4 As shown, this embodiment provides a municipal sludge ceramsite forming device, including a chassis 1, and also including:

[0027] The processing cylinder 3 is fixedly connected to the upper surface of the chassis 1 through the fixing frame 2. A sealing cover 4 is provided above the processing cylinder 3. The sealing cover 4 and the processing cylinder 3 are fixedly connected by bolts. A heating device 26 is symmetrically provided on the inner wall of the processing cylinder 3.

[0028] The mounting ring 25 is fixedly connected to the inside of the processing cylinder 3. The upper surface of the mounting ring 25 is penetrated with a rotating groove for the centrifugal cylinder 10 to rotate. The outside of the centrifugal cylinder 10 is evenly spaced with water outlet holes 11. The outside of the centrifugal cylinder 10 is connected to two feed pipes 14. The bottom of the centrifugal cylinder 10 is connected to multiple discharge pipes 24 through multiple solenoid valves 23.

[0029] An extrusion assembly is disposed inside the centrifugal drum 10 and is used to perform extrusion molding treatment on the sludge inside the centrifugal drum 10;

[0030] A driving assembly is arranged outside the processing cylinder 3 and is used to drive the centrifugal cylinder 10 to rotate synchronously;

[0031] The cutting assembly is arranged inside the processing cylinder 3 and is used to cut the sludge discharged from the discharge pipe 24 .

[0032] The above working principle: when it is necessary to make ceramsite from sludge, the sludge only needs to be added into the centrifugal drum 10 through the feed pipe 14 first. At this time, the driving component starts to run, and the driving component can effectively drive the centrifugal drum 10 to rotate synchronously. During the rotation of the centrifugal drum 10, the sludge will be centrifugally dehydrated. After the sludge is dehydrated, the solenoid valve 23 is opened, and the extrusion component starts to run. The extrusion component can effectively extrude the sludge inside the centrifugal drum 10, and the extruded sludge will be discharged through the discharge pipe 24. While the extrusion component is running, the cutting component also starts to run synchronously. At this time, the cutting component can effectively cut the sludge discharged from the discharge pipe 24, so that the sludge can be turned into small pieces for collection. When the sludge enters the discharge pipe 24, the heating device 26 also starts to run synchronously. At this time, the heating device 26 can further heat and dry the sludge, thereby further improving the drying effect and efficiency of the sludge, and then effectively improving the ceramsite molding effect of the sludge, saving time and effort.

[0033] In order to effectively extrude the sludge inside the centrifugal barrel 10, the extrusion assembly includes an X-shaped plate 15 located above the centrifugal barrel 10, and a plurality of support rods 16 are fixedly connected to the bottom of the X-shaped plate 15, and the bottom ends of the plurality of support rods 16 are fixedly connected to the upper surface of the centrifugal barrel 10, and an electric telescopic rod 17 is fixedly connected to the bottom of the X-shaped plate 15, and a squeezing plate 18 is fixedly connected to the telescopic end of the electric telescopic rod 17. When it is necessary to extrude the sludge inside the centrifugal barrel 10, the electric telescopic rod 17 starts to run, driving the squeezing plate 18 to move synchronously. At this time, the squeezing plate 18 can be used to extrude the sludge inside the centrifugal barrel 10, so that the sludge can be discharged through the discharge pipe 24 for cutting.

[0034] Taking into account that when the sludge is made into ceramsite, the sludge needs to be centrifugally dehydrated first, so the driving assembly includes a first motor 6 fixedly connected to the outside of the processing cylinder 3, the output shaft of the first motor 6 is fixedly connected to the driving rod 7 through a coupling, the other end of the driving rod 7 is fixedly connected to the driving gear 8, and the outside of the centrifugal cylinder 10 is fixedly connected to a driven gear 9 meshing with the driving gear 8. When the sludge needs to be centrifugally dehydrated, it is only necessary to add the sludge into the centrifugal cylinder 10 first. At this time, the first motor 6 starts to run, driving the driving rod 7 to rotate synchronously, the driving rod 7 drives the driving gear 8 to rotate synchronously, the driving gear 8 drives the driven gear 9 to rotate synchronously, and the driven gear 9 drives the centrifugal cylinder 10 to rotate synchronously. At this time, the sludge inside the centrifugal cylinder 10 can be centrifugally dehydrated, thereby further improving the dehydration effect of the sludge and the drying efficiency of the sludge.

[0035] In order to effectively cut the sludge, the cutting assembly includes a support frame 19 fixedly connected to the inside of the processing cylinder 3, and a second motor 20 is fixedly connected to the bottom of the support frame 19. The output shaft of the second motor 20 is fixedly connected to a rotating rod 21 through a coupling, and the top of the rotating rod 21 is fixedly connected to an X-shaped cutting blade 22. When the sludge is squeezed into the discharge pipe 24, the second motor 20 also starts to run synchronously. At this time, the second motor 20 will drive the rotating rod 21 to rotate synchronously, and the rotating rod 21 will drive the X-shaped cutting blade 22 to rotate synchronously. At this time, the X-shaped cutting blade 22 can be used to cut the sludge discharged from the discharge pipe 24, so that the sludge can be effectively made into expanded clay for collection.

[0036] In order to effectively divert the sewage inside the centrifugal drum 10, a guide plate 12 is fixedly connected to the inside of the processing drum 3. The upper surface of the guide plate 12 is penetrated by a rotating groove for the centrifugal drum 10 to rotate. The outside of the processing drum 3 is provided with drainage holes 13 at equal intervals. When the sludge is centrifugally dewatered, the sewage will be thrown out through the water outlet 11 outside the centrifugal drum 10, and then naturally fall to the upper surface of the guide plate 12. At this time, the guide plate 12 can effectively divert the sewage, so that the sewage can be discharged through the drainage holes 13 outside the processing drum 3.

[0037] In addition, in order to conveniently collect and process the processed sludge, a collecting barrel 5 is provided on the upper surface of the chassis 1, and an anti-skid pad is bonded to the bottom of the chassis 1. The bottom of the anti-skid pad has herringbone anti-skid grooves at equal intervals. When the sludge is cut, it will naturally fall into the collecting barrel 5. At this time, the sludge can be collected and processed by the collecting barrel 5. The setting of the anti-skid pad and the herringbone anti-skid groove can effectively prevent the device from being displaced during operation, which may cause danger.
