Description

TECHNICAL FIELD

[0001] The utility model relates to a pulping device, more specifically, it relates to a fly ash auxiliary continuous pulping device. BACKGROUND

[0002] The current common household garbage disposal method includes landfill, composting and incineration. Among them, the incineration technology has the advantages of high volume reduction, large processing capacity and small secondary pollution, and is more and more widely used, accounting for more than 70% of the total amount of garbage disposal.

[0003] Fly ash generated by waste incineration is a hazardous solid waste in China, which cannot be directly put into landfill and needs to be treated by waste removal and danger removal. Washing as the most common and convenient treatment method can effectively remove more than 98% of chlorides and chlorine-containing substances in fly ash. Because fly ash comes from gas phase capture in the incineration process, the manufacturer will spray a large amount of lime to absorb and fix nitrogen and sulfur pollutants when treating gas phase pollutants. A large amount of alkali-soluble substances contained in fly ash dissolve at the water contact interface and form a high-concentration salt solution at the top layer, hindering the subsequent pulping of fly ash. At the same time, the manufacturer uses lime slurry to absorb acidic gases, so that there are 5-8% of blocky fly ash with a particle size of more than 20mm in the fly ash. These hard lumps dissolve slowly in water and are prone to accumulate at pipe corners, causing blockage risk of pipe conveying.

[0004] For example: Chinese patent publication No. CN210210869U, published on March 31, 2020, the name of the utility model is a high-speed pulping and dust removal grouting system, which includes a double-head grouting pump, a high-speed pulping machine and a stirring barrel are arranged on both sides of the double-head grouting pump, the high-speed pulping machine is connected to the bottom of the double-head grouting pump through the stirring barrel and the feeding pipe, forming a continuous circulating grouting system, which does not need to switch the pipeline back and forth, reducing the labor intensity of the operator.

[0020] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0021] Example 1: As Figure 1 The fly ash-assisted continuous pulping device shown includes a pulping chamber 1. A support plate 6 is installed at the bottom of the pulping chamber 1. The support plate 6 is fixedly connected to the pulping chamber 1 in the width direction. A partition plate 3 is installed on the support plate 6. The partition plate 3 is also arranged along the width direction of the support plate 6 and divides the pulping chamber 1 into two areas: a water inlet area 5 on the left and a pulping area on the right. A feed inlet 2 is also provided at the top left side of the pulping chamber 1. The input end of the feed inlet 2 is arranged vertically, and the output end of the feed inlet 2 is arranged horizontally (or inclined). The height of the output end of the feed inlet 2 is higher than the top of the partition plate 3. An inclined surface 4 is provided at the top of the partition plate 3. The inclined surface 4 is inclined downward along the feed direction of the feed inlet 2.

[0022] When fly ash enters through inlet 2, it undergoes a horizontal or oblique throwing motion at the output end of inlet 2. After leaving the output end of inlet 2, the fly ash enters the pulping chamber 1. Some larger particles, having traveled a shorter distance, enter the water inlet zone 5 closer to inlet 2, while some smaller particles, having traveled a longer distance, enter the pulping zone further away from inlet 2. Some material falls onto the inclined surface 4 at the top of the partition plate 3. Since the inclined surface 4 is arranged sloping downwards from the water inlet zone 5 to the pulping zone, this material also enters the pulping zone under the influence of the inclined surface 4. This scheme uses inlet 2 and partition plate 3 to perform preliminary screening of fly ash, separating large and small particles. This allows smaller particles to enter the pulping zone first for pulping, preventing large particles from accumulating and clogging the pulping area.

[0023] In addition, the air inlet channel 12 is arranged in the horizontal channel of the feeding port 2, is arranged at the bottom of the feeding port 2, and is obliquely arranged and penetrates the bottom of the feeding port 2, so that the angle between the direction of the air inlet channel 12 and the feeding direction is as small as possible, and the pushing effect of the air inlet channel 12 on the fly ash material is improved; the air inlet channel 12 is externally connected with an air supply device, when the fly ash material is fed at the horizontal feeding port, the air flow provided in the air inlet channel 12 can provide a certain power for the fly ash material, so that the fly ash material can maintain a certain initial speed at the output end of the feeding port 2 and perform parabolic motion in the pulp chamber 1, thereby preliminarily screening the fly ash material. It should be noted that the baffle 13 structure is arranged at the upper side of the output end of the air inlet channel 12, that is, close to the side of the fly ash material feeding direction, so that when the fly ash material passes through the position of the output end of the air inlet channel 12, the fly ash material can be prevented from entering the air inlet channel 12. Of course, the baffle 13 is arranged to be curved and inclined to a certain extent, so that the resistance of the fly ash material running in the feeding port 2 can be as small as possible, and the feeding effect is ensured.

[0024] The water inlet 5.1 is arranged on the side wall of the pulp chamber 1 of the water inlet area 5, and the water inlet 5.1 is externally connected with a water supply device, which can provide clean water into the water inlet area 5 of the pulp chamber 1 and fill the water inlet area. When the water inlet area is full, the water will overflow from the inclined surface 4 at the top of the partition plate 3 and enter the pulp area. That is, during the screening process of the fly ash material, the large particles of the material directly fall into the clean water in the water inlet area 5 and then settle at the bottom of the water inlet area 5; and the small particles of the material enter the pulp area.

[0025] Specifically, when the water inlet area 5 is full, the water will overflow from the inclined surface 4 at the top of the partition plate 3 and flow downward along the inclined surface 4 on the partition plate 3. Due to the guidance of the inclined surface 4 and the acceleration of the water gravity, the water will fly away from the partition plate 3 (performing oblique throwing motion) after leaving the inclined surface 4 and contact and mix with the smaller fly ash particles in the air. Through continuous operation, the fly ash and water contact is dynamic and synchronous, which can better mix the pulp, avoid the formation of a high-concentration liquid layer on the liquid surface in the pulp area, and affect the subsequent fly ash pulp.

[0026] The adjusting air hole 17 is arranged at the top of the pulp chamber 1, and the adjusting air hole 17 can be externally connected with the atmosphere or can be used to extract and replace the air in the pulp chamber 1, so as to reduce the excessive gas phase water vapor content in the pulp chamber 1, which causes the ash to not flow smoothly.

[0027] A guide inclined plate 14 is arranged on the side wall of the pulp chamber 1 away from the water inlet area 5, and the inclination direction of the guide inclined plate 14 is opposite to the direction of the top inclined surface 4 of the partition plate 3, that is, the connection position of the guide inclined plate 14 with the inner wall of the pulp chamber 1 is higher than the suspended position of the guide inclined plate 14. The guide inclined plate 14 can prevent the fly ash material from adhering to the bottom side wall of the pulp chamber 1, and can timely guide the material or solid-liquid mixture into the lower pulp tank.

[0028] In addition, the support plate 6 is spaced apart from the bottom of the pulp chamber 1, and at the position of the support plate 6 away from the water inlet area 5, the bottom of the pulp chamber 1 forms a partially extended space, the support plate 6 is located in the extended space, and a discharge channel 15 is formed on the upper and lower sides of the pulp chamber 1. Here, the bottom of the pulp chamber 1 is transversely lengthened, which can increase the flow path of the slurry to a certain extent, thereby prolonging the mixing time of the fly ash and the solution and improving the mixing effect. The mixed slurry in the pulp chamber 1 is finally discharged and collected through the discharge channel 15 at the bottom.

[0029] In normal operation, first open the water inlet 5.1, fill the water inlet area 5 with clean water, then open the air inlet channel 12, close the adjusting air hole 17, start feeding the ash bin, the fly ash material enters the pulp chamber 1 through the feed inlet 2, the large particle fly ash material can be separated at the position of the water inlet area 5, and the small particle material is mixed with clean water and discharged and collected in the discharge channel 15. After the pulping is completed, the air inlet channel 12 and the feed inlet 2 are closed, and then the inside of the pulp chamber 1 is cleaned, and the adjusting air hole 17 is opened for dehumidification.

[0030] Embodiment 2: a fly ash auxiliary continuous pulping device as shown in Figure 1 and Figure 2 The device comprises a pulp chamber 1, a support plate 6 is arranged at the bottom of the pulp chamber 1, the support plate 6 is fixedly connected with the pulp chamber 1 in the width direction, a partition plate 3 structure is arranged on the support plate 6, the partition plate 3 is also arranged along the width direction of the support plate 6, and the pulp chamber 1 is divided into two areas, namely a left water inlet area 5 and a right pulping area. A feed inlet 2 is arranged at the top of the left side of the pulp chamber 1, the input end of the feed inlet 2 is vertically arranged, and the output end of the feed inlet 2 is horizontally arranged (or can be inclined arranged). The height position of the output end of the feed inlet 2 is higher than the top position of the partition plate 3, an inclined surface 4 is arranged at the top of the partition plate 3, and the inclination direction of the inclined surface 4 is inclined downward along the feeding direction of the feed inlet 2.

[0031] When the fly ash material enters from the feed inlet 2, it will make a flat or inclined throwing movement at the output end of the feed inlet 2, and after the fly ash material leaves the output end of the feed inlet 2, it enters the pulp chamber 1. Part of the larger particle material has a short movement distance and enters the water inlet area 5 close to the feed inlet 2, part of the smaller particle material has a long movement distance and enters the pulp area away from the feed inlet 2, and part of the material falls on the inclined surface 4 on the top of the partition plate 3. Since the inclined surface 4 is inclined downward from the water inlet area 5 to the pulp area, the part of the material will also enter the pulp area side under the action of the inclined surface 4. The present scheme preliminarily separates the fly ash material through the feed inlet 2 and the partition plate 3, separates the large particle material and the small particle material, so that the small material particles enter the pulp area first for pulping, and the large particle material is prevented from depositing in the pulp area to block the pulp area.

[0032] In addition, an air inlet channel 12 is arranged at the position of the feed inlet 2. The air inlet channel 12 is arranged in the horizontal channel of the feed inlet 2, is arranged at the bottom position of the feed inlet 2, and is arranged obliquely and penetrates the bottom of the feed inlet 2. In this way, the angle between the direction of the air inlet channel 12 and the feeding direction is as small as possible, and the pushing effect of the air inlet channel 12 on the fly ash material is improved. The air inlet channel 12 is externally connected with an air supply device. When the fly ash material is fed at the horizontal position of the feed inlet, the airflow provided in the air inlet channel 12 can provide power for the fly ash material, so that the fly ash material can maintain a certain initial speed at the output end of the feed inlet 2 and make a parabolic movement in the pulp chamber 1, thereby preliminarily separating the fly ash material. It should be noted that a baffle 13 structure is arranged at the output end of the air inlet channel 12. The baffle 13 structure is arranged on the upper side of the output end of the air inlet channel 12, that is, close to the incoming direction of the fly ash material. In this way, when the fly ash material passes through the position of the output end of the air inlet channel 12, the fly ash material can be prevented from entering the air inlet channel 12. Of course, the baffle 13 is arranged to be curved and inclined to a certain extent, so as to reduce the resistance of the fly ash material running in the feed inlet 2 as much as possible and ensure the feeding effect.

[0033] A water inlet 5.1 is arranged on the side wall of the pulp chamber 1 at the water inlet area 5. The water inlet 5.1 is externally connected with a water supply device and can provide clean water into the water inlet area 5 of the pulp chamber 1 and fill the water inlet area. When the water inlet area is full, the water will overflow from the inclined surface 4 on the top of the partition plate 3 and enter the pulp area. That is, during the separation of the fly ash material, the large particle material directly falls into the clean water in the water inlet area 5 and then settles at the bottom position of the water inlet area 5, and the small particle material enters the pulp area.

[0034] Specifically, when the water in the water inlet area 5 is full, the water will overflow from the slope 4 on the top of the partition plate 3 and flow downward along the slope 4 on the partition plate 3. Due to the guidance of the slope 4 and the acceleration effect of the gravity of the flowing water, the flowing water will also fly away from the partition plate 3 (make a slanting throwing motion) after leaving the slope 4 and mix with the smaller fly ash particles in the air. In continuous operation, the fly ash and water contact is a dynamic synchronous contact, which can better mix the pulp and avoid the formation of a high-concentration liquid layer on the liquid surface in the pulping area, affecting the subsequent fly ash pulping.

[0035] The support plate 6 is also provided with a crushing assembly 7, which includes a driving device 7.1, an extension assembly 7.2 and a crushing body 7.3. Specifically, the driving device 7.1 is arranged below the partition plate 3 between the partition plate 3 and the support plate 6. The output end of the driving device 7.1 is connected to the extension assembly 7.2. The extension assembly 7.2 is in the form of a four-folded plate. The extension assembly 7.2 is located near the water inlet area 5, and the driving device 7.1 is located near the pulping area. When the extension assembly 7.2 is in a contracted state, the extension assembly 7.2 is also completely located below the partition plate 3. When the extension assembly 7.2 is extended, the folded plate performs a pushing motion at the bottom of the water inlet area 5, which can collect large-particle fly ash materials at the bottom of the water inlet area 5. A through hole is provided at the bottom of the side wall of the pulping chamber 1 on one side of the water inlet area 5. The through hole is connected to the cleaning chamber 8 outside, that is, the cleaning chamber 8 and the water inlet area 5 are in communication. The crushing body 7.3 can move back and forth between the water inlet area 5 and the cleaning chamber 8 through the through hole structure.

[0036] Specifically, a chute 9 structure is provided at the bottom of the cleaning chamber 8. The chute 9 is located on both sides of the width direction of the cleaning chamber 8. A rolling wheel 10 is arranged in the chute 9. The rolling wheel 10 can roll in the chute 9. One end of the crushing body 7.3 is rotationally connected to the eccentric position of the rolling wheel 10. When the rolling wheel 10 rolls in the chute 9, the rolling wheel 10 also performs a circular motion in the rolling process. Since one end of the crushing body 7.3 is eccentrically rotated on the rolling wheel 10, the end of the crushing body 7.3 connected to the rolling wheel 10 will oscillate up and down.

[0037] Specifically, as shown in FIG. 6, the pulping chamber 1 is provided with a plurality of water inlet areas 5. The water inlet areas 5 are arranged in the pulping chamber 1 in a staggered manner. The water inlet areas 5 are arranged in the pulping chamber 1 in a staggered manner. The water inlet areas 5 are arranged in the pulping chamber 1 in a staggered manner. Figure 2As shown, the width direction size of the crushing body 7.3 is adapted to the width direction size of the washing chamber 8 and the water inlet area 5; the crushing body 7.3 is of a tapered structure at one end, a connecting rod is arranged at the end in the transverse (width direction) and is rotationally connected with the rolling wheel 10, and the other end of the crushing body 7.3 is a cylindrical arc surface 7.3.1; when the tapered end of the crushing body 7.3 swings up and down along with the rolling wheel 10, the arc surface 7.3.1 of the crushing body 7.3 also swings to a certain extent, so as to be able to extrude and crush the large-particle material between the crushing body 7.3 and the telescopic assembly 7.2, thereby forming small-particle material, and dissolving (the undissolved part also forms small-particle material, which does not affect the discharge and blockage of the pulping chamber 1) at the water inlet area 5 position to form a slurry.

[0038] In order to ensure that the rolling wheel 10 only rolls without sliding (slipping), a gear can be arranged on the rolling wheel 10, and a rack can be correspondingly arranged in the sliding groove 9, or other structures can be used instead. This scheme is a conventional technology, and thus will not be described here in detail.

[0039] When the driving device 7.1 is started, the telescopic assembly 7.2 is driven to expand, and the telescopic assembly 7.2 pushes the large-particle material at the bottom of the water inlet area 5 to the arc surface 7.3.1 position of the crushing body 7.3 and forms extrusion, and under the continuous expansion of the telescopic assembly 7.2, the telescopic assembly 7.2 further pushes the crushing body 7.3, further pushes the rolling wheel 10 to roll in the sliding groove 9, thereby driving the crushing body 7.3 to swing and translate, and improving the extrusion effect of the crushing body 7.3 on the large-particle material.

[0040] The braking device 11 is further arranged in the sliding groove 9, the braking device 11 includes an elastic damping member 11.2 and a brake block 11.1, the elastic damping member 11.2 is arranged along the length direction of the sliding groove 9, the brake block 11.1 is arranged near one end of the damping member 11.2 close to the rolling wheel 10, the side of the brake block 11.1 close to the rolling wheel 10 is a circular arc surface, the circular arc surface can be adapted to the surface of the rolling wheel 10, the damping member 11.2 has an elastic effect, can provide more stable movement for the crushing body 7.3, avoid large impact when the crushing body 7.3 is braked, and the circular arc surface on the brake block 11.1 is adapted to the rolling wheel 10, can form a stable braking effect. At the same time, when the telescopic assembly 7.2 is contracted, the damping member 11.2 can also have a certain degree of back-pushing effect.

[0041] The support plate 6 is provided with a discharge port 16 at a position on one side of the washing chamber 8, when the crushing body 7.3 moves to the discharge port 16 position, the small-particle material formed by extrusion can be discharged to the lower side of the support plate 6 through the discharge port 16, mixed with the slurry of the discharge channel 15 and discharged for collection.

[0042] It should be noted that a cleaning port 8.1 is further arranged on the upper portion of the cleaning chamber 8, through which clean water can be filled into the cleaning chamber 8 to perform backwashing on the cleaning chamber 8, so as to flush away the residual slurry in the cleaning chamber 8.

[0043] An adjusting air hole 17 is further arranged in the pulp preparation chamber 1, which is arranged at the top of the pulp preparation chamber 1. The adjusting air hole 17 can be connected with the atmosphere or can be used to replace the air in the pulp preparation chamber 1, so as to reduce the excessive water vapor content in the gas phase in the pulp preparation chamber 1, which can cause the unsmooth dust falling.

[0044] A guide inclined plate 14 is arranged on the side wall of the pulp preparation chamber 1 away from the water inlet area 5.

The guide inclined plate 14 can prevent the fly ash material from adhering to the bottom side wall of the pulp preparation chamber 1, and can timely guide the material or solid-liquid mixture into the pulp tank below.

[0045] In addition, the support plate 6 is spaced apart from the bottom of the pulp preparation chamber 1, and a space is formed on the bottom of the pulp preparation chamber 1 at the position of the support plate 6 away from the water inlet area 5. The support plate 6 is located in the space, and a discharge channel 15 is formed on the upper and lower sides of the pulp preparation chamber 1. The bottom of the pulp preparation chamber 1 is horizontally lengthened, which can increase the flow path of the slurry to a certain extent, thereby prolonging the mixing time of the fly ash and the solution and improving the mixing effect. Finally, the mixed slurry in the pulp preparation chamber 1 is discharged and collected through the discharge channel 15 at the bottom.

[0046] In normal operation, the water inlet 5.1 is first opened, and then the water inlet area 5 is filled with clean water.
