Description

Technical Field

[0001] The present invention relates to the technical field of waste treatment, and in particular to a solid waste treatment device. Background Art

[0002] Boiler ash refers to the minerals in the coal that undergo certain physical and chemical changes under the high temperature caused by the combustion of the coal in the furnace and are discharged into the well. This is called slag.

[0003] The slag needs to be transported to the slag yard using a boiler slag discharge device (since the slag in the boiler will cause problems such as contamination, slagging, corrosion and wear of the heating surface, affecting the normal operation of the boiler, the slag must be removed effectively and timely. A part of the slag is discharged from the slag hopper behind the grate of the layer-burning furnace, the cold ash hopper at the bottom of the furnace of the pulverized coal furnace, or the slag outlet and slag ash pool at the bottom of the liquid slag discharge furnace), which is called slag discharge. The timely transportation and treatment of high-temperature slag is a necessary link for the safe operation of the boiler. Since the slag still has a relatively high temperature, the residual heat can be recovered to save energy. At the same time, the slag needs to be crushed for packaging and transportation or processing and reuse. In the prior art, the treatment equipment for solid waste is complex and diverse, and requires additional transportation and reprocessing equipment for further treatment.

In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0058] See also Figure 1-11 , the present invention discloses a solid waste treatment device, comprising: a feeding part 1, a cooling part 2, a crushing part 3 and a collecting part 4 which are arranged in sequence;

[0059] The feeding part 1 is used to receive the material and transport it to the cooling part 2;

[0060] The cooling part 2 is used to cool the material and send it to the crushing part 3;

[0061] The crushing part 3 is used to crush materials;

[0062] The collecting part 4 is used to collect the materials crushed by the crushing part 3 and pack them;

[0063] The collecting part 4 comprises two groups of bearing swing arms 41, on which the two groups of bearing swing arms 41 are provided with winding mechanisms 42, on which the two groups of winding mechanisms 42 are provided with packaging bags 44 and positioning mechanisms, and the positioning mechanisms are used to control the discharge length of the packaging bags 44, and a swinging member 43 is provided at one end of the bearing swing arm 41 away from the winding mechanism 42;

[0064] The packaging bag 44 is respectively rolled up on the two groups of the rolling mechanisms 42. The packaging bag 44 includes an extension portion 441 and a heat-sealing portion 442. The heat-sealing portion 442 is distributed around the extension portion 441.

[0065] The two groups of the carrying swing arms 41 are distributed in a V-shape, so as to be relatively far away from or close to the traction packaging bag 44 and unfolded or folded in half, so as to receive the crushed solid waste;

[0066] The two groups of the carrying swing arms 41 are also provided with sealing mechanisms 45, which are used to heat-seal the heat-sealing portion 442 of the current packaging bag discharging portion 44 when the packaging bag discharging portion 44 is in a folded state, and to heat-seal the butt joint of the next packaging bag discharging portion 44, so that one end of the packaging bag discharging portion 44 on the two groups of the carrying swing arm discharging portions 41 is connected together;

[0067] The swinging member 43 includes a weight sensor and a power mechanism. The weight sensor is used to detect the weight of the packaging bag 44 . The power mechanism is used to drive the two sets of winding mechanisms 42 and the sealing mechanism 45 to move closer to each other, so as to fold the packaging bag 44 and seal the packaging bag 44 .

[0068] Specifically, the cooling unit 2 includes a cooling pool 21 and a feeding roller 22;

[0069] The feeding roller 22 is tiltedly arranged in the cooling pool 21, and the cooling pool 21 is filled with a coolant;

[0070] The cooling pool 21 is also provided with a bearing wheel 23 for driving the feeding roller 22 to rotate;

[0071] The feeding roller 22 is provided with a spiral blade 221 , and the feeding roller 22 is provided with a water inlet hole.

[0072] When the present application is used, the specific steps include: the feeding part 1 is used to receive the material and transfer it to the feeding roller 22, and one end of the feeding roller 22 is located in the cooling pool 21, so that the material with temperature can be fully contacted with the coolant for cooling, and as the feeding roller 22 rotates, the spiral blade 221 inside it can lift the cooled material to the other end of the feeding roller 22, and the other end of the feeding roller 22 corresponds to the crushing part 3;

[0073] After the cooled material enters the crushing part 3, it is crushed. It should be noted that the crushing part 3 is inclined relative to the feeding roller 22. After the material is crushed into uniform size, the material can fall into the collecting part 4 along the inclined direction of the crushing part 3.

[0074] At the collecting part 4, the two groups of the load-bearing swing arms 41 will pull the reeling mechanism 42 at the end thereof relatively away from each other, so that the packaging bag 44 rolled up on the reeling mechanism 42 can be unfolded to receive the falling materials;

[0075] In the above process, after the packaging bag 44 is unfolded, the crushed materials fall onto the extension part 441 of the packaging bag 44 and are stored in the extension part 441. The extension part 441 is stretched by gravity. When the weight sensor detects that the load-bearing capacity of the packaging bag 44 reaches a predetermined value, the power mechanism drives the load-bearing swing arm 41 to swing relatively, thereby folding the packaging bag 44, and the packaging bag 44 is sealed by the sealing mechanism 45 provided on the load-bearing swing arm 41.

[0076] The specific sealing steps include: during the folding process of the packaging bag 44, such as Figure 7 As shown, the two sets of heat-sealing parts 442 are relatively overlapped. At this time, the two sets of sealing mechanisms 45 abut against the overlapping heat-sealing parts 442 and heat-seal the parts to complete the packaging of the crushed materials for subsequent processing.

[0077] It should be noted that a limiting bearing ring corresponding to the bearing wheel 23 is provided on the feeding roller 22, and the limiting bearing ring is in contact with the bearing wheel 23. It should be supplemented that a power mechanism is also provided in at least one bearing wheel 23 to provide power to drive the feeding roller 22 to rotate.

[0078] In the present application, the feed part 1 is fixedly arranged on one side of the cooling pool 21;

[0079] The feed portion 1 extends into the feed roller 22 to transport the material between the spiral blades 221. It should be noted that the coolant in the cooling pool 21 is water, and the cooling pool 21 is also provided with a circulating water pipe and a treatment pool corresponding to the circulating water pipe to filter impurities and dust in the cooling water. A waste heat recovery mechanism may also be provided to maximize the use of resources.

[0080] In the present application, the crushing part 3 is arranged obliquely on one side of the cooling pool 21 relative to the feeding roller 22;

[0081] The crushing part 3 includes a grinding drum 31, a grinding mechanism 32 and a power unit 33 for driving the grinding mechanism 32;

[0082] The grinding mechanism 32 is disposed in the grinding drum 31;

[0083] The inner wall of the grinding drum 31 is provided with grinding teeth 311 .

[0084] Furthermore, the output end of the power unit 33 is provided with a transmission rod 331 corresponding to the grinding mechanism 32. In another embodiment, the cooling pool 21 and the collecting part 4 are further provided with a driving mechanism for driving the grinding roller 31 to rotate, so as to drive the grinding roller 31 to rotate relative to the grinding mechanism 32.

[0085] The power unit 33 is fixedly arranged on the collecting part 4. It should be supplemented that the crushing part 3 and related structures are not limited to the above-mentioned structures in the present application, and may be replaced by other structures that can be easily thought of by those skilled in the art.

[0086] Specifically, the collecting part 4 further includes a bearing frame, and the bearing frame is used to support the crushing part 3;

[0087] The collecting portion 4 is also provided with a discharging portion 46 corresponding to the carrying swing arm 41. The discharging portion 46 is used to receive the packaging bag 44. After the materials are collected, they can be discharged along the discharging portion 46 to facilitate subsequent material connection. The discharging portion 46 is a conveyor belt, wherein the conveyor belt is a commonly used technical means in the prior art, and therefore is not described in detail in this application.

[0088] It should be noted that the present application also includes a controller, and a rotating shaft is provided at the output end of the power mechanism, the load-bearing swing arm 41 is provided on the rotating shaft, and a weight sensor is provided on the conveyor belt to detect the weight of the material between the two load-bearing swing arms 41. When the weight exceeds a predetermined value, it is fed back to the controller, and the controller controls the operation of the power mechanism to drive the load-bearing swing arm 41 to deflect and reset, such as a belt scale.

[0089] It should be noted that the sealing mechanism 45 includes a heat sealing mechanism 451 and a cutting mechanism 452 corresponding to the heat sealing portion 442;

[0090] The heat sealing mechanism 451 is in two groups and is distributed on both sides of the cutting mechanism 452;

[0091] The heat sealing mechanism 451 is used to connect the heat sealing portions 442 of two groups of packaging bags 44 and the heat sealing portions 442 of two adjacent groups of packaging bags 44 after the packaging bags 44 are folded in half;

[0092] The cutting mechanism 452 is used to cut the packaging bag 44 after heat sealing.

[0093] Furthermore, the heat-sealing mechanism 451 located at the bottom of the cutting mechanism 452 is in an inverted U-shape, and is used to heat-seal the heat-sealing portion 442 of the packaging bag 44 after carrying the material.

[0094] In the above structure, if Fig. 9 As shown, the two sets of heat-sealing mechanisms 451 can heat-seal the connection of the continuous packaging bags 44, and the cutting mechanism 452 can be used to cut the connection of the continuous packaging bags 44, so that the heat-sealed packaging bags are separated and discharged through the subsequent discharging portion 46;

[0095] Specifically, the heat-sealing mechanism 451 below can heat-seal the heat-sealing portion 442 of the packaging bag 44 containing the material, thereby forming a seal to prevent the material from being scattered and dust from being dispersed during the subsequent transportation process;

[0096] The upper heat sealing mechanism 451 can be used to connect the packaging bags 44 on the two sets of winding mechanisms 42 and form them into a whole for subsequent reuse.

[0097] It should be noted that the positioning mechanism includes a fixed shaft 421 and a winding roller 422 sleeved outside the fixed shaft 421;

[0098] The fixed shaft 421 is provided with a positioning pin 423, and the fixed shaft 421 is provided with a resisting spring 424 corresponding to the positioning pin 423;

[0099] The winding roller 422 is provided with an opening 4221;

[0100] The positioning latch 423 is used to lock the winding roller 422 and to contact and retract to unlock the winding roller 422 when the two sets of winding mechanisms 42 are close to each other.

[0101] In the above process, if Fig.11 As shown, when the two groups of load-bearing swing arms 41 swing relative to each other under the drive of the power mechanism, the two groups of positioning pins 423 retract against each other, and at this time, the fixed shaft 421 and the winding roller 422 are unlocked, and the winding roller 422 drives the winding roller 422 to rotate under the action of the gravity of the packaging bag 44 containing the material, and then, after the heat sealing mechanism 451 connects the packaging bags 44 on the two groups of winding mechanisms 42, when the two groups of load-bearing swing arms 41 swing away from each other under the drive of the power mechanism, the packaging bags 44 on the winding mechanism 42 can be pulled out, until the winding roller 422 rotates one circle, and the positioning pins 423 are again engaged in the opening 4221.

[0102] It is easy to imagine that the packaging bag 44 on the winding roller 422 will not block the opening 4221 , and the opening 4221 can be set at both ends of the winding roller 422 .

[0103] It should be added that the circumference of the winding roller 422 is equal to half the length of the packaging bag 44 , so that when the two sets of winding rollers 422 rotate relative to each other, the sum of the rotation lengths of the two sets of winding rollers 422 is the same as the length of the packaging bag 44 .

[0104] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0105] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0106] In addition, "plurality" means two or more.

[0107] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
