Description

TECHNICAL FIELD

[0001] The present application relates to the field of sludge ceramite preparation, in particular to a production equipment for preparing high-performance ceramite from fly ash heavy metal sludge. BACKGROUND

[0002] With the gradual increase of environmental pollution, the sludge produced by sewage plants is mainly disposed of in cement kilns, and the sludge is disposed of as garden nutrient soil, and the heat-drying treatment is diversified. Due to the limited demand, in order to realize recycling, the sludge comprehensive utilization of making ceramite from sludge and shale as raw materials is a new way. Specifically, the sludge and shale are processed into ceramite and then heated in a rotary kiln. Since the sludge produced by the sewage plant has a high water content, it cannot be directly used, and usually the staff will dry the sludge produced by the sewage plant to a water content that meets the requirements, and then mix it with shale to make ceramite. However, due to the artificial drying of sludge to reduce the water content, it is greatly affected by the weather, and the drying process is long, which reduces the processing efficiency of the ceramite processing mechanism.

[0003] Chinese patent CN207391235U discloses a sludge drying device of a ceramite processing mechanism, which comprises a sludge storage tank, a pre-drying cellar, a screw conveyor and a heating device for heating the sludge in the pre-drying cellar. The screw conveyor is used to convey the sludge into the pre-drying cellar, and the feed inlet of the screw conveyor is used to receive the sludge in the sludge storage tank.

[0004] The above scheme can heat the sludge in the pre-drying cellar by the heating device, and when the preset water content is reached, the sludge is taken out, which improves the processing efficiency. However, in order to improve the drying efficiency in the process of preparing ceramite, the ceramite is usually placed in a mold for drying, and after the drying is completed, the worker needs to knock the mold to make the ceramite fall out of the mold for quality identification and then break it, which increases the workload of the worker. Moreover, the traditional mold does not have a pushing-out structure, and when the ceramite is not easy to fall out of the mold, the worker needs to knock the mold, which cannot realize automatic unloading.

DETAILED DESCRIPTION

[0033] In order to further understand the features, technical means and specific purposes and functions of the present application, the present application is described in further detail below in combination with the drawings and specific embodiments.

[0034] Reference Figure 1 , Figure 2 and Figure 9The utility model provides a kind of production equipment of fly ash heavy metal sludge preparation high-performance ceramsite, including base plate 1 and unloading device 2;Unloading device 2 includes first inclined plate 21, conveying device 22, trigger device 23, turnover device 24, pressing plate 25, cleaning device 26, push-out device 27 and transmission assembly 28;First inclined plate 21 is fixedly arranged on the length direction of base plate 1 one end, and the one end of first inclined plate 21 is close to base plate 1 than the one end of first inclined plate 21 is far from base plate 1, and discharge chute is opened on first inclined plate 21;Conveying device 22 is arranged on base plate 1 along the length direction of base plate 1, and the upper portion of base plate 1 is used to place mould 3, and mould 3 is used to receive ceramsite, and conveying device 22 can drive mould 3 to move along the length direction of base plate 1;Trigger device 23 is arranged on first inclined plate 21, and trigger device 23 can be triggered after mould 3 contacts with first inclined plate 21, and one side of trigger device 23 is provided with controller, and trigger device 23 can prevent mould 3 on first inclined plate 21 from sliding down;Turnover device 24 is rotationally arranged on base plate 1, and the one end of turnover device 24 far from first inclined plate 21 rotates around the one end of turnover device 24 close to first inclined plate 21, and trigger device 23 is controlled to operate by controller;The upper portion of first inclined plate 21 is provided with extension plate, and pressing plate 25 is rotationally arranged on the side wall of extension plate, and pressing plate 25 can press mould 3 on first inclined plate 21;Cleaning device 26 is arranged on the lower portion of first inclined plate 21, and cleaning device 26 can clean ceramsite in mould 3;Push-out device 27 is arranged on pressing plate 25 and first inclined plate 21 respectively, and push-out device 27 can push mould 3 after cleaning away from first inclined plate 21;Transmission assembly 28 is arranged between turnover device 24 and pressing plate 25, and turnover device 24 drives pressing plate 25 to rotate by transmission assembly 28.

[0035] The mold 3 containing the ceramsite is placed on the base plate 1, the conveying device 22 is started, so that the mold 3 on the base plate 1 moves along the length direction of the base plate 1, when the mold 3 contacts the first inclined plate 21, the trigger device 23 is started, the trigger device 23 controls the rotation of the turnover device 24 through the controller, the turnover device 24 overturns the mold 3 on the base plate 1, the mold 3 is inverted on the first inclined plate 21 under the action of the turnover device 24, the trigger device 23 is popped up after being triggered by the mold 3, the trigger device 23 can prevent the mold 3 on the first inclined plate 21 from sliding down, so that the turnover device 24 can ensure that the mold 3 does not slide down along the inclined direction of the first inclined plate 21 when overturning the mold 3, the mold 3 is inverted on the first inclined plate 21 after completing the overturning, the ceramsite in the mold 3 can fall through the discharging groove on the first inclined plate 21, then the turnover device 24 returns to the original position, the pressing plate 25 presses the mold 3 through the transmission assembly 28, it is worth noting that the pressing plate 25 and the turnover device 24 rotate through the transmission assembly 28, when the turnover device 24 is not started, the end surface of the pressing plate 25 is parallel to the upper end surface of the first inclined plate 21, the distance between the pressing plate 25 and the first inclined plate 21 is the same as the thickness of the mold 3, when the turnover device 24 is started, the pressing plate 25 rotates, that is, the included angle between the pressing plate 25 and the first inclined plate 21 gradually increases, so that the mold 3 can fall on the first inclined plate 21 without being blocked by the pressing plate 25, at the same time, the cleaning device 26 can clean the residual ceramsite in the mold 3, after the cleaning is completed, the mold 3 is pushed out by the pushing-out device 27, and the cycle is repeated, so that the device can automatically clean and recycle the ceramsite in the mold 3, reducing the workload of manual labor.

[0036] Referring to Figure 1 , Figure 5 and Figure 6 : the trigger device 23 comprises a trigger pressing piece 231, a pressure sensor, a guide rod 232, a limiting block 233 and a spring 234; the first inclined plate 21 is vertically provided with a through groove, the trigger pressing piece 231 is vertically and slidingly arranged in the through groove; the pressure sensor is arranged at the upper part of the trigger pressing piece 231; the guide rod 232 is vertically and fixedly arranged at the lower part of the trigger pressing piece 231; the limiting block 233 is arranged below the trigger pressing piece 231, the guide rod 232 penetrates through the limiting block 233, the guide rod 232 and the limiting block 233 are slidingly matched, and a gap is formed between the limiting block 233 and the trigger pressing piece 231; the spring 234 is arranged in the gap along the axis of the guide rod 232.

[0037] When the mold 3 approaches the first inclined plate 21 under the driving of the conveying device 22, the mold 3 will first press the trigger pressing piece 231, and the pressure sensor arranged on the trigger pressing piece 231 can monitor the pressure. When the mold 3 completely presses the trigger pressing piece 231, the pressure value of the pressure sensor reaches the maximum, and the pressure sensor controls the turnover device 24 to start through the controller. At this time, the mold 3 has not contacted the first inclined plate 21, and the turnover device 24 starts. Therefore, the mold 3 is not completely separated from the conveying device 22, and the conveying device 22 will continue to push the first inclined plate 21, so that the first inclined plate 21 is completely contacted with the first inclined plate 21. At this time, the end of the first inclined plate 21 sweeps the trigger pressing piece 231, and the trigger pressing piece 231 is reset under the action of the spring 234. The reset trigger pressing piece 231 has a supporting effect on the end of the mold 3. Therefore, when the turnover device 24 drives the mold 3 to turn over, the end of the mold 3 away from the first inclined plate 21 can rotate around the end of the mold 3 close to the first inclined plate 21. Therefore, the mold 3 can be inverted on the first inclined plate 21, so that the ceramsite in the mold 3 is discharged.

[0038] With reference to Figure 2 and Figure 5 : The trigger device 23 further comprises a guide assembly 235 and a locking device 236. The guide assembly 235 is arranged on one side of the limiting block 233 along the inclination direction of the first inclined plate 21, and is used for guiding the limiting block 233 to move along the inclination direction of the first inclined plate 21. The locking device 236 is arranged on the trigger pressing piece 231 and the through groove, respectively.

[0039] When the mold 3 is inverted on the first inclined plate 21, the trigger pressing piece 231 will still generate an inclined downward pressure due to the weight of the mold 3 and the influence of the inclination angle of the first inclined plate 21. At this time, the mold 3 will slide downward, and the trigger pressing piece 231 will be pushed to slide in the through groove along the inclination direction of the first inclined plate 21 under the guidance of the guide assembly 235. When the trigger pressing piece 231 contacts the side wall of the through groove, the locking device 236 is locked. Therefore, the trigger pressing piece 231 can be prevented from being pressed down by the mold 3, and the phenomenon of the mold 3 sliding downward is prevented.

[0040] With reference to Figure 2 , Figure 10 and Figure 12 : The guide assembly 235 comprises a protrusion 2351 and a guide groove 2352. The protrusion 2351 is fixedly arranged on the side wall of the limiting block 233 along the inclination direction of the first inclined plate 21. The lower part of the first inclined plate 21 is provided with an extension ear, and the guide groove 2352 is arranged on the extension ear along the inclination direction of the first inclined plate 21. The protrusion 2351 and the guide groove 2352 are in sliding cooperation.

[0041] When the mold 3 exerts a pushing force on the trigger pressing member 231 along the tilting direction of the first tilting plate 21, the protrusion 2351 provided on the side wall of the limiting block 233 will slide relative to the guide groove 2352. Since the tilting direction of the guide groove 2352 is parallel to the tilting direction of the first tilting plate 21, it can be ensured that the trigger pressing member 231 slides along the tilting direction of the first tilting plate 21.

[0042] Reference Figure 5 and Figure 6 The locking device 236 includes a first locking tooth 2361 and a second locking tooth 2362; the first locking tooth 2361 is vertically and evenly arranged on the side of the through groove near the substrate 1; the second locking tooth 2362 is vertically and evenly arranged on the side of the trigger pressing member 231 near the substrate 1, and the first locking tooth 2361 and the second locking tooth 2362 are engaged.

[0043] When the trigger press 231 is pushed by the mold 3 located on the first inclined plate 21 along the inclined direction of the first inclined plate 21, the first locking tooth 2361 and the second locking tooth 2362 are locked, so the mold 3 cannot press the trigger press 231 after it comes into contact with the side wall of the through groove.

[0044] Reference Figure 2 , Figure 7 and Figure 9 The cleaning device 26 includes a first rotary driver 261, a synchronous rotation component 262, a rotating shaft 263, and a cleaning component 264. The first rotary driver 261 is disposed below the first inclined plate 21 along the width direction of the first inclined plate 21. The rotating shaft 263 is rotatably disposed in the lower drop trough along the width direction of the first inclined plate 21. The first rotary driver 261 is fixedly connected to one of the rotating shafts 263. Multiple rotating shafts 263 are disposed and are evenly arranged along the inclination direction of the first inclined plate 21. The synchronous rotation component 262 is connected to the same side end of all the rotating shafts 263 respectively, and the synchronous rotation component 262 and the rotating shaft 263 are in a transmission cooperation. The cleaning component 264 is disposed on the rotating shaft 263.

[0045] After the mold 3 is inverted onto the first inclined plate 21, the first rotary driver 261 is activated. The first rotary driver 261 drives all the rotating shafts 263 to rotate through the synchronous rotating component 262. Since the rotating shaft 263 is equipped with a cleaning component 264, when the rotating shaft 263 rotates, the cleaning component 264 on the rotating shaft 263 will rotate synchronously, and the cleaning component 264 cleans the ceramic particles in the mold 3.

[0046] Reference Figure 7 and Figure 8The cleaning assembly 264 comprises a sliding rod 2641, a first weight 2642 and a second weight 2643; the rotating shaft 263 is provided with a sliding groove along the radial direction of the rotating shaft 263, the sliding rod 2641 is slidingly arranged in the sliding groove, and both ends of the sliding rod 2641 extend out of the sliding groove; the first weight 2642 is fixedly arranged at the end of the sliding rod 2641; the second weight 2643 is fixedly arranged at the end of the sliding rod 2641 away from the first weight 2642, and the weight of the second weight 2643 is greater than that of the first weight 2642.

[0047] Due to the different weights of the second weight 2643 and the first weight 2642, when the rotating shaft 263 rotates, the object with a greater weight will be thrown out under the action of centrifugal force. In order to facilitate understanding, the weight of the second weight 2643 is set to be greater than that of the first weight 2642, so that after the rotating shaft 263 rotates, the second weight 2643 will extend out under the action of centrifugal force. The second weight 2643 that extends out collides with the ceramsite remaining in the mold 3. Since the sliding rod 2641 is slidingly arranged on the rotating shaft 263, when the second weight 2643 receives a greater resistance, the sliding rod 2641 will be pushed to slide in the sliding groove, preventing the cleaning brush from being too soft to achieve the cleaning effect, and also preventing the use of rigid collision from damaging the mold 3.

[0048] Referring to Figure 2 , Figure 7 and Figure 8 : The pushing-out device 27 comprises a second rotary driver 271, a belt conveyor 272, rollers 273 and a second inclined plate 274; the second rotary driver 271 is arranged on the upper part of the pressing plate 25 along the width direction of the first inclined plate 21; the belt conveyor 272 is arranged at the end of the second rotary driver 271 along the width direction of the first inclined plate 21, and the lower part of the belt conveyor 272 can contact the mold 3; the rollers 273 are provided in plurality, and the rollers 273 are rotatably arranged on the first inclined plate 21 along the inclined direction of the first inclined plate 21, and the rollers 273 can contact the lower part of the inverted mold 3; the second inclined plate 274 is arranged on one side of the first inclined plate 21, and the inclination angle of the second inclined plate 274 is the same as that of the first inclined plate 21.

[0049] After the cleaning is finished, the second rotary driver 271 is started, the second rotary driver 271 drives the belt conveyor 272 to start, at this time, the pressing plate 25 has the pressing effect on the mold 3, the belt conveyor 272 arranged on the pressing plate 25 also contacts the mold 3, and the first inclined plate 21 is arranged with the roller 273, so that the friction of the mold 3 during the movement is reduced, the mold 3 on the first inclined plate 21 is pushed to the second inclined plate 274 under the belt conveyor 272, the pushed-out mold 3 is guided to slide out under the second inclined plate 274, and the recycling of the mold 3 is realized.

[0050] With reference to Figure 1 and Figure 11 The overturning device 24 comprises a third rotary driver 241 and an overturning plate 242; the third rotary driver 241 is arranged below the base plate 1 along the width direction of the base plate 1; and the overturning plate 242 is fixedly arranged on the output end of the third rotary driver 241.

[0051] When the trigger device 23 is triggered, the third rotary driver 241 is started by the controller, and the third rotary driver 241 drives the overturning plate 242 to rotate. The overturning plate 242 drives the mold 3 on the base plate 1 to overturn.

[0052] With reference to Figure 9 and Figure 10 The transmission assembly 28 comprises a synchronous wheel 281 and a synchronous belt 282; the synchronous wheel 281 is arranged in two, and the two synchronous wheels 281 are arranged on one side of the hinge joint between the overturning plate 242 and the pressing plate 25, respectively; the axis of the synchronous wheel 281 on the side of the overturning plate 242 is collinear with the axis of the output shaft of the third rotary driver 241; the synchronous belt 282 is sleeved on the two synchronous wheels 281, and the synchronous wheel 281 and the synchronous belt 282 are in transmission cooperation.

[0053] When the third rotary driver 241 is started, the synchronous wheel 281 on the side of the overturning plate 242 also rotates, and all the synchronous wheels 281 rotate through the transmission of the synchronous belt 282, so that the pressing plate 25 can synchronously rotate.
