This invention is applicable to the field of waste treatment technology.

Description

Technical Field

[0012] ,

[0011] ,

[0001] The present invention relates to the technical field of garbage treatment, and more precisely relates to a pusher mechanism and a pyrolytic garbage treatment system thereof. Background Art

[0002] Garbage is waste that has lost its use value and cannot be utilized. It is an important link in the material cycle and is solid or fluid matter that is not needed or useless. In large cities with a dense population, garbage treatment is a headache problem.

[0003] Large garbage treatment stations rely on financial subsidies. For garbage transfer stations that require small vehicles to collect and multi-stage transfer, not only is the operating cost high, but there are also secondary pollutions such as transfer leakage and long-term stacking with odor volatilization.

[0004] Currently, in a pyrolytic gasification garbage treatment system, a pusher mechanism is used to send garbage into a combustion furnace, where it is pyrolyzed into combustible gas in an oxygen-deficient environment, and heavy metals, nitrogen oxides, and sulfur dioxide are controlled in a reducing inert environment, reducing the synthesis of nitrogen oxides, sulfur dioxide, and dioxins at the source, and ensuring that harmful substances are fully burned at high temperatures. The pusher mechanism mainly has a pusher part arranged in cooperation with a material cavity. The material cavity is used to hold the garbage to be treated, and a driving mechanism is set to drive the pusher part to move linearly, thereby pushing the garbage to be treated in the material cavity into the combustion furnace;

[0005] However, the following problems often occur during the use of the pusher mechanism:

[0006] Uneven pusher quantity: When the volume ratio of garbage in the material cavity is small, the amount of garbage pushed into the combustion furnace each time by the pusher part is low, and it cannot meet the continuous combustion requirement for the garbage supply, which may cause the situation of interruption of incineration in the incinerator;

[0007] When the volume ratio of garbage in the material cavity is large, when the garbage containing more moisture enters the combustion furnace, incomplete combustion will occur, and it may also cause the situation of incomplete combustion leading to interruption of incineration.

[0008] In summary, the pusher mechanisms of existing pyrolytic gasification garbage treatment equipment generally have problems such as uneven pusher quantity, low continuity of incineration treatment, and a large amount of manual operation. Summary of the Invention

[0009] Aiming at the deficiencies and defects of the prior art, a pusher mechanism with uniform pusher and high continuity of processing and treatment and a pyrolytic garbage treatment system thereof are provided.

[0010] To achieve the above object, the present invention provides the following technical solutions.

[0011] A pusher mechanism, comprising:

[0012] A material cylinder, wherein a material cavity is provided inside the material cylinder, and an opening is provided on the side wall of the material cylinder to match the material cavity;

[0013] A first pressure plate is provided on both sides of the opening. The inner end of the first pressure plate is hinged and the first pressure plate can rotate about the hinge point.

[0014] First baffle plates are respectively provided at both ends of the opening, and two first pressing plates are placed inside the two first baffle plates. The inner sides of the two first baffle plates, together with the inner sides of the two first pressing plates and the material cavity, form a receiving space for accommodating the waste to be processed.

[0015] The rotation of the two first pressure plates with their outer ends moving away from each other has a movement trajectory that relatively expands and gradually increases the volume of the accommodating space; the rotation of the two first pressure plates with their outer ends moving closer to each other has a movement trajectory that relatively contracts and gradually decreases the volume of the accommodating space.

[0016] The two first pressing plates unfold relative to each other, and the waste to be processed is placed into the accommodating space. The two first pressing plates retract relative to each other to compress the waste to be processed.

[0017] The pushing mechanism further includes a pushing part, which is disposed at one end of the material chamber. Moving the pushing part pushes the waste to be processed in the material chamber out of the discharge port at one end of the material chamber.

[0018] With the above structure, the feeding mechanism of the present invention has the following advantages compared with the prior art: the two first pressing plates are rotated away from each other to unfold relative to each other until the two first pressing plates are in a lateral position. At this time, the volume of the accommodating space increases to the maximum volume. The waste to be processed is put into the accommodating space. Further, the two first pressing plates are rotated close to each other to retract relative to each other. At this time, the volume of the accommodating space gradually decreases. The waste to be processed is compressed by the squeezing of the inner side of the first pressing plate, the inner side of the first baffle plate and the inner side wall of the material cavity, so that the waste is effectively dehydrated and the water content of the waste to be processed is reduced.

[0019] In addition, the compression of the waste increases the volume of waste per unit volume, resulting in a larger amount of waste being pushed out of the discharge port when the pushing section pushes the waste out, reducing the number of pushing operations and saving energy and reducing emissions.

[0020] As an improvement of the present invention, a driving mechanism is also included, the driving mechanism including a lead screw and a lead screw bearing, the lead screw bearing being connected to the pusher part, the lead screw and the lead screw bearing being configured to cooperate, the rotation of the lead screw driving the lead screw bearing to move axially to drive the pusher part to move.

[0021] As an improvement of the present invention, the drive mechanism further includes a rotating shaft, a first gear, a second gear, a third gear, and a fourth gear. The first gear is sleeved on the outside of the rotating shaft and is coaxially arranged with the rotating shaft. A clutch is also provided between the first gear and the rotating shaft. The clutch is used to control the transmission connection or disconnection between the rotating shaft and the lead screw. The front end of the rotating shaft is coaxially connected with the tail end of the lead screw.

The two baffle plates are symmetrically distributed around the center line of the material cavity and are positioned one-to-one with the position of the first pressing plate.

[0024] The two baffles can slide relatively far apart or relatively close together.

[0025] As an improvement of the present invention, a primary pressing mechanism is provided between the corresponding barrier plate and the first pressing plate. The primary pressing mechanism includes a second baffle plate, a third baffle plate and a second pressing plate. The second baffle plate is disposed at the outer end of the first pressing plate and extends outward. The third baffle plate is disposed below the inner end of the barrier plate and extends downward.

[0026] As an improvement of the present invention, one end of the second pressure plate is hinged to the upper end of the second baffle plate by a hinge, and the other end of the second pressure plate is hinged to the lower end of the third baffle plate by a hinge.

[0027] As an improvement of the present invention, the rotation of the outer ends of the two first pressure plates away from each other drives the sliding of the two barrier plates away from each other through the second pressure plate to open the discharge port; the rotation of the outer ends of the two first pressure plates close to each other drives the sliding of the two barrier plates close to each other through the second pressure plate to close the discharge port.

[0028] As an improvement of the present invention, the first pressure plate is an arc-shaped plate structure, and its inner diameter is consistent with the inner diameter of the material cavity. When the two first pressure plates are closed to their maximum position, the axis of the two first pressure plates is coaxial with the axis of the material cavity.

[0042] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0043] Please see Figure 1-9 As shown, the present invention provides a sewage drainage pipe seepage detection device with simple structure, easy operation, accurate detection results, and accurate judgment of seepage location.

[0044] To achieve the above objectives, the present invention provides the following technical solutions.

[0045] A feeding mechanism, comprising:

[0046] The material cylinder 1 has a material cavity 1.1 inside, and the side wall of the material cylinder 1 has an opening 1.2 to cooperate with the material cavity 1.1;

[0047] A first pressure plate 2 is provided on both sides of the opening 1.2. The inner end of the first pressure plate 2 is hinged, and the first pressure plate 2 can rotate with the hinge as the center.

[0048] First baffle plates 3 are respectively set at both ends of the opening 1.2, and two first pressing plates 2 are placed inside the two first baffle plates 3. The inside of the two first baffle plates 3, together with the inside of the two first pressing plates 2 and the material cavity 1.1, form a holding space for holding the waste to be processed.

[0049] The rotation of the two first pressure plates 2 with their outer ends moving away from each other has a relatively unfolding movement trajectory that gradually increases the volume of the accommodating space; the rotation of the two first pressure plates 2 with their outer ends moving closer to each other has a relatively contracting movement trajectory that gradually decreases the volume of the accommodating space.

[0050] The two first pressing plates 2 unfold relative to each other, and the waste to be processed is placed into the accommodating space. The two first pressing plates 2 then retract relative to each other to compress the waste to be processed.

[0051] The feeding mechanism also includes a feeding part 4, which is configured at one end of the material chamber 1.1. Moving the feeding part 4 will push the waste to be processed in the material chamber 1.1 out of the discharge port 1.3 at one end of the material chamber 1.1.

[0052] The two first pressing plates 2 are rotated away from each other to unfold relative to each other until the two first pressing plates 2 are in a horizontal position. At this time, the volume of the accommodating space increases to the maximum volume. The waste to be processed is put into the accommodating space. Further, the two first pressing plates 2 are rotated closer to each other to retract relative to each other. At this time, the volume of the accommodating space gradually decreases. The waste to be processed is compressed by the squeezing of the inner side of the first pressing plate 2, the inner side of the first baffle plate 3, and the inner side wall of the material cavity 1.1, so that the waste is effectively dehydrated and the water content of the waste to be processed is reduced.

[0053] In addition, the volume of waste per unit volume can be increased after the waste to be processed is compressed. As a result, when the material pushing section 4 pushes the waste to be processed out of the discharge port 1.3, more waste to be processed is pushed out, reducing the number of times the material is pushed out, thus saving energy and reducing emissions.

[0054] As an improvement of the present invention, a driving mechanism is also included. The driving mechanism includes a lead screw 5.1 and a lead screw bearing. The lead screw bearing is connected to the pushing part 4, and the lead screw 5.1 and the lead screw bearing are configured to cooperate. The rotation of the lead screw 5.1 drives the lead screw bearing to move axially, thereby moving the pushing part 4. After the above improvement, the use of the lead screw 5.1 and the lead screw bearing for driving, and the rotation of the lead screw 5.1 driving the pushing part 4 to move through the lead screw bearing, results in a linear and smooth movement of the pushing part 4, effectively preventing the overflow of waste to be processed during pushing.

[0055] As an improvement of the present invention, the drive mechanism further includes a rotating shaft 5, a first gear 6, a second gear 6.2, a third gear 6.3, and a fourth gear 6.4. The first gear 6 is sleeved on the outside of the rotating shaft 5 and is coaxially arranged with the rotating shaft 5. A clutch 6.1 is also provided between the first gear 6 and the rotating shaft 5. The clutch 6.1 is used to control the transmission connection or disconnection between the rotating shaft 5 and the lead screw 5.1. The front end of the rotating shaft 5 is coaxially connected with the tail end of the lead screw 5.1.

[0056] The second gear 6.2 and the third gear 6.3 are respectively connected to the first gear 6. The fourth gear 6.4 is connected to the second gear 6.2. The third gear 6.3 is coaxially connected to the first connecting shaft 6.31, which is connected to the inner end of one of the first pressure plates 2. The rotation shaft of the first pressure plate 2 is coaxially connected to the first connecting shaft 6.31. The fourth gear 6.4 is coaxially connected to the second connecting shaft 6.41, which is connected to the inner end of the other first pressure plate 2. The rotation shaft of the first pressure plate 2 is coaxially connected to the second connecting shaft 6.41.

[0057] After the above improvements, the rotating shaft 5 rotates, and the rotating shaft 5 and the lead screw 5.1 rotate coaxially, thereby driving the pusher part 4 to move;

[0058] When clutch 6.1 is engaged, the first gear 6 rotates, which in turn drives the second gear 6.2 and the fourth gear 6.4 to rotate. The second gear 6.2 drives the third gear 6.3 to rotate, and the first connecting shaft 6.31, coaxially mounted on the third gear 6.3, drives the first pressure plate 2 on the left to rotate. The second connecting shaft 6.41, coaxially mounted on the fourth gear 6.4, drives the first pressure plate 2 on the right to rotate. Through the gear transmission mechanism design, the torque transmitted between the gears is large, resulting in a large rotational torque, linear and smooth rotation of the two first pressure plates 2. This improves the compression effect of the waste to be processed as the accommodating space gradually decreases.

[0059] A bracket 12 can be installed and detached at the rear end of the barrel 1. The bracket 12 allows the rotating shaft 5 to pass through. A retainer is connected to the bracket 12, and the second gear 6.2 is connected to the retainer.

[0060] As an improvement of the present invention, the upper end of the first baffle plate 3 is provided with a material box 7 for storing waste, the lower part of the material box 7 is arranged opposite to the opening 1.2, and two baffle plates 8 are provided at the material box. The two baffle plates 8 are symmetrically distributed around the center line of the material cavity 1.1, and their positions correspond one-to-one with the positions of the first pressing plate 2.

[0061] The two baffle plates 8 can slide relatively far apart or relatively close together. After the above improvement, the material box 7 is used to accumulate waste to be processed. When the two baffle plates 8 slide relatively far apart, the discharge port is opened, and the accumulated waste to be processed feeds into the storage space. When the two baffle plates 8 slide relatively close together, the discharge port is closed, and the accumulated waste to be processed cannot feed into the storage space. After the improvement, continuous feeding of the storage space can be achieved by moving the baffle plates 8, which has the characteristics of high automation and high continuity of device operation.

[0062] As an improvement of the present invention, a primary pressing mechanism is provided between the corresponding barrier plate 8 and the first pressing plate 2. The primary pressing mechanism includes a second baffle plate 9, a third baffle plate 10 and a second pressing plate 11. The second baffle plate 9 is located at the outer end of the first pressing plate 2 and extends outward. The third baffle plate 10 is located below the inner end of the barrier plate 8 and extends downward.

[0063] One end of the second pressing plate 11 is hinged to the upper end of the second baffle plate 9, and the other end of the second pressing plate 11 is hinged to the lower end of the third baffle plate 10. After the above improvement, the waste to be processed discharged from the discharge port is compressed by the pressing mechanism once, which can achieve a better compression effect on the waste to be processed.

[0064] As an improvement of the present invention, the rotation of the outer ends of the two first pressing plates 2 away from each other drives the sliding of the two blocking plates 8 away from each other through the second pressing plate 11, thereby opening the discharge port; the rotation of the outer ends of the two first pressing plates 2 close to each other drives the sliding of the two blocking plates 8 close to each other through the second pressing plate 11, thereby closing the discharge port. After the above improvement, when the first pressing plate 2 compresses the waste to be processed, the primary pressing mechanism is linked to compress the waste to be processed simultaneously, and the two work together to compress the waste to be processed, improving the compression effect; in addition, the primary pressing mechanism moves the blocking plates 8 to close the discharge port, preventing material from being discharged, and when the primary pressing mechanism compresses the waste, the waste to be processed cannot overflow from the discharge port, resulting in a good sealing effect of the device and further improving the compression effect;

[0065] When the outer ends of the first pressing plate 2 rotate away from each other, the primary pressing mechanism opens in conjunction with the primary pressing mechanism, and the primary pressing mechanism also opens the discharge port in conjunction with the baffle plate 8, so that the waste to be processed can fall into the pressing space and the receiving space formed by the primary pressing mechanism.

[0066] As an improvement of the present invention, the first pressing plate 2 is an arc-shaped plate structure with an inner diameter consistent with the inner diameter of the material cavity 1.1. When the two first pressing plates 2 are retracted to their maximum position, the axis of the two first pressing plates 2 is coaxial with the axis of the material cavity 1.1. After the above improvement, when the first pressing plate 2 is retracted to its limit position, the inner side of the first pressing plate 2 is in contact with the opening 1.2 of the material cavity 1.1. The large rotational stroke of the first pressing plate 2 can achieve a better compression effect on the waste to be processed.

[0067] In addition, when the pushing section 4 pushes the waste to be processed in the material chamber 1.1, the first pressing plate 2 can prevent the waste to be processed from overflowing, resulting in a better pushing effect. Furthermore, the first pressing plate 2 will not interfere with the movement of the pushing plate, thus improving the stability of operation.

[0068] As an improvement of the present invention, the pusher part 4 is a cylindrical structure and is disposed inside the material cylinder 1. The lead screw bearing is connected to the tail end of the pusher part 4, and the pusher part 4 has a hole 4.1 for the rotating shaft 5 to extend into. After the above improvement, the structural layout is more reasonable, the space occupied is reduced, and it is conducive to the miniaturization of the device.

[0069] As an improvement of the present invention, the inner wall of the material cavity 1.1 is provided with a seepage hole 1.4, and the material cylinder 1 is provided with a water guiding cavity 1.5 corresponding to the position of the material cavity 1.1, communicating with the seepage hole 1.4. The water guiding cavity 1.5 is connected to a drainage channel 1.51. After the above improvement, when the waste to be processed is compressed, the squeezed water can enter the water guiding cavity 1.5 through the seepage hole 1.4 and be discharged through the drainage channel 1.51, so that the squeezed water can flow out of the material cavity 1.1, further reducing the water content.

[0070] Working principle: The compression space of the first-stage pressing mechanism is the inner space formed by the inner side of the second baffle plate 9, the inner side of the third baffle plate 10, the inner side of the second pressing plate 11, and the first baffle plate 3.

[0071] Usage steps:

[0072] First, the waste to be processed is piled up in the material box 7. When the waste to be processed is piled up in the material box 7, the two first pressing plates 2 are in the extreme position of being retracted, the two second pressing plates 11 are in the position of being at the minimum relative distance, and the two baffle plates 8 are in the state of closing the discharge port. At this time, the accommodating space and the compression space of the first pressing mechanism are both in the maximum volume state. The baffle plate 8 fully opens the discharge port, and the pushing part 4 is located on the right side of the opening 1.2.

[0073] After the waste awaiting processing has accumulated in the material bin 7,

[0074] Furthermore, the clutch 6.1 is engaged to enable the rotating shaft 5 to rotate in conjunction with the first gear 6. At this time, the forward rotation of the rotating shaft 5, in conjunction with the rotation of the first gear 6, causes the lead screw 5.1 to rotate. The rotation of the lead screw 5.1 drives the pusher 4 to move along the inside of the material cylinder 1 towards the pusher opening via the lead screw bearing.

[0075] The rotation of the first gear 6 is linked to the rotation of the second gear 6.2 and the fourth gear 6.4. The second gear 6.2 is linked to the rotation of the third gear 6.3. Under the linkage of the first connecting shaft 6.31 and the second connecting shaft 6.41, the outer ends of the two first pressure plates 2 are rotated closer to each other. The two first pressure plates 2 gradually retract, so that the area of ​​the accommodating space gradually decreases. At this time, the two first pressure plates 2 are linked to the movement of the two second pressure plates 11 closer to each other. The compression space of the first-stage pressing mechanism gradually decreases. The second pressure plates 11 are linked to the lateral sliding of the two baffle plates 8 closer to each other, so that the discharge port gradually closes.

[0076] When the two first pressing plates 2 are in their retracted limit position, the waste to be processed in the accommodating space is compressed into the material chamber 1.1, the waste to be processed in the first-level compression space remains in the compression space, the discharge port is in a completely closed state, and the pushing part 4 is still in the material cylinder 1 on the right side of the opening 1.2;

[0077] At this time, the waste to be processed accumulated in the material box 7 can enter the holding space and the compression space of the first-stage pressing mechanism through the discharge port;

[0078] Furthermore, the clutch 6.1 is engaged and disengaged so that the shaft 5 cannot rotate in conjunction with the first gear 6. At this time, the shaft 5 continues to rotate in the forward direction. The shaft 5 is linked to the lead screw 5.1 to rotate. The lead screw 5.1 rotates to drive the pusher part 4 to continue moving towards the pusher port through the lead screw bearing. After the pusher part 4 pushes the compressed waste to be processed out of the material chamber 1.1 out of the pusher port;

[0079] Furthermore, the clutch 6.1 is engaged and disengaged, the shaft 5 is rotated in the opposite direction, and the screw 5.1 rotates to drive the pusher part 4 away from the pusher opening through the screw bearing. When the pusher part 4 returns to the right side of the opening 1.2;

[0080] Furthermore, the clutch 6.1 is engaged, and the shaft 5 continues to rotate in the opposite direction. The first gear 6 rotates in conjunction with the second gear 6.2 and the fourth gear 6.4. The second gear 6.2 rotates in conjunction with the third gear 6.3. Under the linkage of the first connecting shaft 6.31 and the second connecting shaft 6.41, the outer ends of the two first pressing plates 2 rotate away from each other, and the two first pressing plates 2 gradually unfold, so that the area of ​​the accommodating space gradually increases. At this time, the two first pressing plates 2 move away from each other in conjunction with the two second pressing plates 11. The compression space of the first-stage pressing mechanism gradually increases. The second pressing plates 11 slide laterally away from each other in conjunction with the two baffle plates 8, so that the discharge port gradually opens. The waste to be processed in the material box 7 is replenished to the compression space and the accommodating space through the discharge port.

[0081] By repeating the above steps, the waste to be processed in the material bin 7 can be continuously compressed and pushed out from the push port.
