Description

Technical Field

[0001] The present invention relates to the technical field of slag treatment, and in particular to an environmentally friendly treatment device and method for waste incineration slag. Background Art

[0002] As people's living standards continue to improve, their material lives are greatly satisfied. Correspondingly, the amount of garbage generated in life has also increased. In order to reduce the volume of a large amount of domestic garbage and other mixtures and eliminate the toxic and harmful substances in domestic garbage, high-temperature incineration is usually used. After high-temperature incineration, a certain amount of incineration slag and other substances will remain.

[0003] In fact, the incineration slag produced by high-temperature incineration of domestic waste contains stones, ashes and other substances. The incineration slag will be used in the production of building materials such as roadside bricks in the later stage. If the incineration slag contains too much ash, the structural strength of the roadside bricks will not meet the requirements. If the incineration slag is not cleaned, the alkalinity of the resulting building products will be too high, which will cause serious corrosion to the metal parts or steel bars inside the building products. Therefore, before the incineration slag is reused in an environmentally friendly manner, it is necessary to clean the incineration slag to reduce its alkalinity.

[0004] The Chinese patent application number CN202010726792.6 discloses a domestic waste incineration furnace slag cleaning and crushing device, which includes a mounting shell for mounting equipment and having a cavity inside, a feed port being provided at the top of the mounting shell, an internal shell being provided inside the mounting shell through a connecting bracket, the outer circumference of the internal shell and the inner circumference of the mounting shell forming a conveying channel, a rotating block being provided above the inside of the mounting shell, the bottom of the rotating block being connected to the top of the rotating shaft, the bottom of the rotating shaft passing through the internal shell and being connected to the output end of an external rotating motor, a receiving plate with a ring-shaped structure being provided between the rotating block and the feed port, a central through hole being provided in the center of the receiving plate and being axially opposite to the feed port up and down, the top surface of the rotating block being a circular arc surface, and the bottom of the receiving plate being provided The surface is parallel to the top surface of the rotating block, and a flushing structure is provided on the edge of the central through hole of the receiving plate to flush water to the bottom surface of the receiving plate. A downward-slanted drain plate is provided in an annular shape on the top of the internal shell. A number of drain holes are provided on the surface of the drain plate, which are connected to the water receiving channel inside the internal shell, and a water receiving trough is provided at the end of the water receiving channel. Although this scheme can clean the ash on the surface of the slag, the slag is simply rinsed with water and then slides down by itself. In this process, the slag is not allowed to stay in the air for a certain period of time, which may easily lead to incomplete cleaning of the ash on the slag. At the same time, a large number of water droplets will exist in the process of falling and will not be removed. Therefore, a large number of water droplets are likely to appear in the subsequent process, which increases the difficulty of slag treatment.

[0005] Therefore, an environmentally friendly treatment device and method for waste incineration slag are invented to solve the above problems. Summary of the Invention

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0040] In the prior art, when removing ash from slag, the slag is generally rinsed as a whole with clean water. This not only fails to thoroughly clean the ash remaining on the slag, but also makes it very troublesome to clean the water marks remaining on the slag. It also increases the cleaning cost and reduces the cleaning efficiency. This embodiment is specially invented to solve the above problems.

[0041] like Figure 1 and Figure 2 As shown, this embodiment provides an environmentally friendly treatment device for waste incineration slag, including a shell 1 and a cleaning cover 2. An adjusting block 3 is rotatably provided in the cleaning cover 2 for rotating and colliding the slag. A blanking plate 604 close to the cleaning cover 2 is fixed in the shell 1, and the support ring 601 is fixedly connected to the blanking plate 604 through a support tube 605. A driving motor 606 is fixed on the blanking plate 604, and the output end of the driving motor 606 passes through the blanking plate 604 and is fixedly connected to the adjusting block 3.

[0042] Two water tanks 7 are provided on the side of the blanking plate 604 away from the cleaning hood 2. A cleaning ring 8 is fixed at the opening of the cleaning hood 2 in the shell 1. The inner end of the cleaning ring 8 fits with the inside of the cleaning hood 2. The water tank 7 and the cleaning ring 8 are connected by a water pipe. A feed port 9 connected to the cleaning hood 2 is provided on the shell 1. A plurality of inclined plates 10 are provided between the water tank 7 and the shell 1. A circuitous channel is formed between the plurality of inclined plates 10 to slow down the rate at which the slag slides.

[0043] In actual use, first start the drive motor 606, which drives the adjustment block 3 to rotate. The adjustment block 3 has a certain elasticity. At the same time, the water in the water tank 7 is pumped into the cleaning ring 8 through the water pipe by the water pump. The water in the cleaning ring 8 is sprayed into the cleaning cover 2. When the slag falls from the feed port 9 onto the adjustment block 3 in the cleaning cover 2, the slag contacts the inner wall of the cleaning cover 2 under the action of centrifugal force and elastic force. At this time, the water can wash the ash on the slag. After contacting the cleaning cover 2, the slag falls to the bottom by itself under the action of its own gravity. On the blanking plate 604, since the blanking plate 604 is inverted V-shaped, and a water sprinkling plate is provided at the connection between the water tank 7 and the blanking plate 604, the droplets carrying the ash fall into the water tank 7 again. At the same time, a filtering mechanism is provided in the water tank 7 for filtering the droplets containing ash to ensure the cleanliness of the flushing water. The cleaned slag falls into the circuitous channel formed between the multiple inclined plates 10, and a hot air mechanism can be added in the circuitous channel to facilitate drying of the moisture on the slag. The slag then flows out of the shell 1 and enters the crushing mechanism for crushing. Example 2

[0044] During use, it was found that the slag slid down by itself after being simply rinsed with water. During this process, the slag was not allowed to stay for a certain period of time, resulting in incomplete cleaning of the ash on the slag. At the same time, a large number of water droplets would exist in the falling process and were not removed. Therefore, a large number of water droplets would easily appear in the subsequent process, increasing the difficulty of slag treatment. Therefore, further improvements were made based on the above embodiments.

[0045] like Figures 2 to 8 As shown, the blocking assembly 4 includes a plurality of baffles 401 distributed along the circumference of the regulating block 3, and a discharge plate 402 is slidably connected between two adjacent baffles 401. When the discharge plate 402 slides, the slag slides down from the gap between the discharge plate 402 and the baffle 401;

[0046] The adjustment assembly 5 includes multiple adjustment plates 501 hinged to the baffle 401. The swing directions of two adjacent adjustment plates 501 are different, which are used to slow down the speed of slag falling. When the two adjacent adjustment plates 501 swing relative to each other, the unloading plates 402 corresponding to the two relatively swinging adjustment plates 501 slide, causing the slag on the unloading plate 402 to slide off.

[0047] The driving assembly 6 is disposed in the adjusting block 3 and is used to drive the adjusting plate 501 to perform periodic alternating swings.

[0048] The sealing assembly 4 includes a plurality of guide grooves 403 provided on the adjusting block 3, the discharge plate 402 is slidably connected to the corresponding guide grooves 403, the free ends of the baffle 401 and the discharge plate 402 are in contact with the inner wall of the cleaning hood 2, and the opposing surfaces of the two adjacent baffles 401 are both inclined surfaces for guiding the slag to slide down.

[0049] The adjustment assembly 5 includes a rotating shaft 502 rotatably connected to the baffle 401, and the rotating shaft 502 is fixedly connected to the corresponding unloading plate 402. A transmission mechanism 503 located in the adjustment block 3 is provided between the rotating shaft 502 and the unloading plate 402. When the rotating shaft 502 rotates, the transmission mechanism 503 drives the unloading plate 402 to slide.

[0050] The transmission mechanism 503 includes a cylinder 5031 fixedly connected to the rotating shaft 502 . A guide groove 5032 is formed on the circumferential side of the cylinder 5031 . An insertion rod 5033 is fixed on the discharge plate 402 and inserted into the corresponding guide groove 5032 .

[0051] The drive assembly 6 includes two support rings 601 located in the adjustment block 3. The two support rings 601 are fixedly connected. A plurality of circumferentially distributed racks 602 are provided on the opposite surfaces of the two support rings 601. The racks 602 on the two support rings 601 are staggered. A gear 603 that can engage with the racks 602 is fixed on the rotating shaft 502.

[0052] In actual use, first, during the rotation of the adjusting block 3, the adjusting block 3 drives the baffle 401 and the discharge plate 402 to rotate synchronously, so that the slag falls onto the baffle 401 through the feed port 9, and the gear 603 on one of the rotating shafts 502 first meshes with the rack 602 on the lower support ring 601, so that the corresponding rotating shaft 502 drives the adjusting plate 501 to swing in the direction of rotation of the adjusting block 3. At this time, the gear 603 on the next rotating shaft 502 along the rotation direction of the adjusting block 3 first meshes with the rack 602 on the upper support ring 601, so that the corresponding rotating shaft 502 drives the adjusting plate 501 to swing in the opposite direction of rotation of the adjusting block 3. At this time, the two adjusting plates 501 swing into an inverted V shape and block the corresponding discharge plate 402. At the same time, the gear 603 on the next rotating shaft 502 along the rotation direction of the adjusting block 3 first meshes with the rack 602 on the upper support ring 601 The rack 602 on the lower support ring 601 is engaged, so that the corresponding rotating shaft 502 drives the adjustment plate 501 to swing in the direction of rotation of the adjustment block 3. At this time, the two adjacent adjustment plates 501 form a V-shaped state, and do not block the corresponding unloading plate 402. The subsequent adjustment plates 501 follow the above-mentioned swinging law. In the process of the gear 603 engaging with one of the racks 602, multiple adjustment plates 501 can swing into a wavy shape, and the peaks or troughs therein change alternately. In the process of multiple adjustment plates 501 swinging to a certain angle, under the action of the swinging inclined surface of the adjustment plate 501, the falling slag can be buffered at a certain speed, so that the flushing water can fully flush the slag. At the same time, the slag falls on the unloading plate 402 and stays for a period of time, which is also convenient for the flushing water to contact and clean the slag again.

[0053] At the same time, the cylinder 5031 on the rotating shaft 502 corresponding to the two adjusting plates 501 forming an inverted V shape rotates, and the cylinder 5031 rotates in the direction of rotation of the adjusting block 3, and the guide groove 5032 provided on the cylinder 5031 is composed of an arc-shaped straight groove and an oblique groove, and the initial position of the insertion rod 5033 is located at the inflection point of the straight groove and the oblique groove. At this time, the insertion rod 5033 slides along the oblique groove on the cylinder 5031, and the cylinder 5031 drives the unloading plate 402 to slide along the guide groove 403 toward the direction of the adjusting block 3 through the guide groove 5032 and the insertion rod 5033. At this time, the cleaning cover 2, the baffle 401 and the unloading plate are A gap appears between the material plates 402. Under the action of the centrifugal force of the rotation of the adjusting block 3, the slag on the discharge plate 402 passes through the gap and falls onto the discharge plate 604. The water droplets on the slag will be separated from the slag under the action of the centrifugal force, reducing the residual moisture on the slag. At the same time, the cylinder 5031 on the rotating shaft 502 corresponding to the two V-shaped adjusting plates 501 rotates. At this time, the insertion rod 5033 slides along the straight groove on the cylinder 5031, so that the corresponding discharge plate 402 does not slide, so that the slag can stay on the discharge plate 402 for a period of time, ensuring the effect of cleaning the ash on the slag.

[0054] When one of the gears 603 is no longer engaged with the rack 602 on the lower support ring 601, the gear 603 is engaged with the rack 602 on the upper support ring 601, so that the gear 603 drives the adjustment plate 501 to swing in the opposite direction of the rotation of the adjustment block 3 through the rotating shaft 502, and the gear 603 adjacent to the rotation direction of the adjustment block 3 is engaged with the rack 602 on the lower support ring 601. At this time, the gear 603 drives the adjustment plate 501 to swing in the direction of rotation of the adjustment block 3 through the rotating shaft 502, and the two adjustment plates 501 swing from the inverted V-shaped state to the V-shaped state. At the same time, the insertion rod 5033 slides from the oblique groove of the guide groove 5032 to the straight groove, so that the cylinder 5031 The unloading plate 402 is driven by the insertion rod 5033 and the guide groove 5032 to slide along the guide groove 403 in the direction away from the adjusting block 3, so that there is no gap between the corresponding unloading plate 402, the cleaning cover 2 and the baffle 401, and the unloading plates 402 corresponding to the two adjusting plates 501 that swing from a V shape to an inverted V shape slide in the direction of the adjusting block 3, so that a gap appears between the unloading plate 402 and the cleaning cover 2, which facilitates the slag to fall from the gap under the action of centrifugal force, and when the unloading plates 402 corresponding to the two adjusting plates 501 that form the inverted V shape slide, the adjusting plates 501 can play a certain shielding effect, preventing the slag from falling directly from the gap, thereby avoiding reducing the cleaning effect.

[0055] In summary, by setting up multiple swingable adjustment plates 501 and discharge plates 402, and the adjustment plates 501 swing according to a certain rule to form a V or inverted V shape, not only can the falling slag be rebounded and slowed down to a certain extent, which is beneficial for the flushing water to fully flush the ash on the slag, but the unobstructed part of the discharge plate 402 can make the slag stay for a certain period of time, so that the slag can be fully cleaned, and the obstructed part of the discharge plate 402 can slide and form a gap during the swinging of the adjustment plate 501. Under the action of centrifugal force, the slag on the discharge plate 402 is thrown to the gap and falls, and at the same time, the water droplets on the slag can be thrown away, reducing the water content of the slag during the sliding process, and during the swinging process, it is convenient to process the water droplets on the slag and comprehensively clean the slag, thereby improving the efficiency and quality of slag cleaning. Example 3

[0056] This embodiment also provides an environmentally friendly treatment method for waste incineration slag, comprising the following steps:

[0057] S1: First, the drive motor 606 is started, which drives the regulating block 3 to rotate, shakes off the slag entering the cleaning cover 2 through the feed port 9, and rinses the slag through the cleaning ring 8;

[0058] S2: The slag then falls onto the regulating plate 501 and the discharge plate 402, and the regulating plate 501 swings with the rotation of the regulating block 3. The swinging inclined surface of the regulating plate 501 can rebound the slag and slow down its descending speed, so that the flushing water can fully flush the slag.

[0059] S3: Next, the slag is thrown off the discharge plate 402 and falls into the shell 1 under the action of centrifugal force, and the water droplets on the slag are separated under the action of centrifugal force;

[0060] S4: Finally, the slag is drained for a second time through the blanking plate 604, and the slag on the blanking plate 604 falls to the outside of the shell 1 through a circuitous channel formed by multiple inclined plates 10 for the next crushing process.
