Description

Technical Field

[0001] The invention belongs to the field of incinerator equipment, and in particular relates to a device for preparing alkali-corrosion-resistant high-thermal-shock castables for an organic waste liquid incinerator. Background Art

[0002] The castable used in the incineration process of organic waste liquid is an important refractory material that can withstand high temperature and chemical erosion and protect the incinerator from damage.

[0003] When selecting castables, its performance and corrosion resistance at high temperatures need to be considered. When preparing alkali-resistant high thermal shock castables, first of all, various raw materials need to be prepared, including the main crystal phase (such as corundum, mullite), binders (such as calcium silicate, phosphate), additives (such as water reducers, plasticizers), etc. These raw materials need to be strictly screened and measured to ensure the quality of the castables.

[0004] Then, put the prepared raw materials into the mixer and mix them until all the ingredients are evenly distributed. During this process, it may be necessary to add an appropriate amount of water or other liquid medium so that the raw materials can form a slurry with a certain fluidity; pour the mixed slurry into the mold, remove the internal bubbles by vibration and other means, so that it is evenly distributed and fills the entire mold. Then, move the mold to the curing room for curing.

[0005] It can be seen from the above that the preparation of castables must ensure that the selected raw materials meet the standards. For example, by optimizing the particle grading and selecting suitable aggregates, the performance of the castable material can be improved. A certain amount of water must be used in the preparation of castables, that is, dry powder is mixed with appropriate water to make refractory castables. The fluidity of the castable in the preparation of the castable body will affect the quality of construction. In order to obtain better refractory castable components or linings, the amount of water must be strictly controlled, because increasing the amount of water will cause the aggregate and powder to accumulate separately, making the structure of the refractory castable or lining loose and the corrosion resistance reduced. Therefore, in order to limit the amount of water, fine particles can be used to improve the fluidity of the refractory castable.

[0006] Although coarse particles will reduce the fluidity of the refractory castable slurry, they can increase the mechanical strength of the refractory castable after firing, reduce post-firing shrinkage, and reduce material costs; in addition, coarse particles (aggregates) can also create channels for the escape of water vapor from the refractory castable components or linings during the monotonic process, thereby preventing serious damage to the refractory castable components or lining structure when water vapor escapes.

[0007] Therefore, the preparation of alkali-resistant and high thermal shock castables requires the use of aggregates that meet the requirements, that is, the aggregates need to be screened and dried, and the ratio of aggregates, fine powder and water needs to be strictly controlled. The current castable preparation process is independent. For example, the aggregates are screened and then dried, and the dried aggregates are weighed and proportioned with fine powder and then mixed. The process is cumbersome and the castable preparation efficiency is low. Summary of the invention

[0008] In response to the above technical problems, the present invention provides an alkali-resistant high thermal shock castable preparation device for an organic waste liquid incinerator, which solves the problem that the current castable preparation process is independent, the aggregate is screened and dried, and the dried aggregate is mixed with fine powder by weighing and proportioning, the process is cumbersome, and the castable preparation efficiency is low.

DETAILED DESCRIPTION

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and thus only show the components related to the present invention.

[0028] Embodiment 1: reference Figure 1-9 As shown, the present invention comprises a support frame 1, on which an aggregate feed box 2, a screening mechanism, a discharging assembly, a fine powder feed mechanism, a lifting mechanism 21, and a weight measuring device 22 are fixedly mounted.

[0029] The screening mechanism comprises a cylindrical and obliquely arranged shell 3, a screening drum 4 is rotatably connected in the shell 3, a material storage cavity 5 is arranged between the screening drum 4 and the shell 3, a first material feed port 6 is arranged at the left end of the screening drum 4, a first material discharge port 7 is arranged at the right end of the screening drum 4, a plurality of primary screening holes 8 are arranged on the side of the screening drum 4, a plurality of obliquely arranged first shovel plates 9 are fixedly connected inside the screening drum 4, and a second material discharge port 10 communicating with the material storage cavity 5 is arranged at the lower end of the side of the shell 3;

[0030] The castable used in the incineration process of organic waste liquid is an important refractory material that can withstand high temperatures and chemical erosion to protect the incinerator from damage. When selecting castables, its performance at high temperatures and its ability to resist erosion need to be considered. First, various raw materials need to be prepared, including the main crystal phase (such as corundum, mullite), binders (such as calcium silicate, phosphate), additives (such as water reducers, plasticizers), etc. These raw materials need to be strictly screened and measured to ensure the quality of the castable.

[0031] Screen various raw materials according to the particle size requirements to ensure that the raw material particle size meets the requirements of the formula design. For example, corundum can be screened into different particle size levels, such as 0-1mm, 1-3mm, 3-5mm, etc., so as to make reasonable grading.

[0032] The prepared raw materials are put into the aggregate feed box 2. A crushing mechanism can be provided in the aggregate feed box 2 to further crush the larger-sized aggregates in the aggregate feed box 2. The crushed aggregates enter the screening drum 4 through the first feed port 6, so that the maximum particle size of the aggregates entering the screening drum 4 is not greater than the maximum particle size grade requirement. When the screening drum 4 rotates, the first shoveling plate 9 is used to scoop up the aggregates at the bottom of the screening drum 4. When the scooped aggregates are driven to the upper part by the rotating screening drum 4, the aggregates on the first shoveling plate 9 begin to scatter, so that it is convenient to screen the aggregates in the screening drum 4. After screening, the smaller-sized aggregates enter the storage chamber 5 through the primary screening hole 8. Since the outer shell 3 and the screening drum 4 are inclined, the aggregates in the storage chamber 5 will be discharged through the second discharge port 10, and the larger-sized aggregates in the screening drum 4 will be discharged from the first discharge port 7.

[0033] The fine powder feeding mechanism includes a fine powder storage box 11, a peristaltic pump 12 and an air compressor 13. The peristaltic pump 12 is connected to a suction pipe 14 and a discharge pipe 15. The suction pipe 14 is inserted into the bottom end of the fine powder storage box 11. The air compressor 13 is connected to an air outlet pipe 16, and the air outlet pipe 16 is connected to the discharge pipe 15.

[0034] Although larger-sized aggregates will enhance the mechanical strength of the refractory castable after firing, reduce post-firing shrinkage, and reduce material costs, coarse particles will reduce the fluidity of the refractory castable slurry; therefore, the preparation of the castable should be in accordance with the experimental requirements, and a certain ratio of larger-sized aggregates and fine powder should be added. The fine powder feeding mechanism will quantitatively transport the fine powder for proportioning. When the fine powder is fed, the peristaltic pump 12 is turned on. The peristaltic pump 12 generates negative pressure to attract the fine powder through the suction pipe 14 and discharge it from the discharge pipe 15. The fine powder can be regarded as a fluid. The peristaltic pump is an existing technology. It consists of three parts: a driver, a pump head, and a hose. The roller is used to clamp the hose filled with fluid to form a negative pressure in the tube, and the liquid flows accordingly. The peristaltic pump has high repeatability and stability. The precision; an air compressor is a device that converts mechanical energy into gas pressure energy. It is mainly used to generate and provide compressed air. Compressed air as a power source can accelerate the discharge rate of fine powder.

[0035] The discharging assembly comprises a discharging pipe 17 with an opening at the lower end, the discharging pipe 17 is connected with a first connecting pipe 18, a second connecting pipe 19, a third connecting pipe and a pressure relief valve 23, the first connecting pipe 18 is rotatably connected to the first discharging port 7, the second connecting pipe 19 is fixedly connected to the discharge pipe 15, and the third connecting pipe is fixedly connected to a water volume control pump;

[0036] A mixing container 20 is provided below the discharge pipe 17 . The discharge pipe 17 is sleeved on the upper opening of the mixing container 20 . The weight measuring device 22 is below the mixing container 20 . The moving end of the lifting mechanism 21 is below the mixing container 20 .

[0037] Aggregates discharged from the first discharge port 7 enter the mixing container 20 through the first connecting pipe 18 and the discharge pipe 17. When preparing the raw material feed, the lifting mechanism 21 contracts and does not apply force to the mixing container 20. At this time, the mixing container 20 is on the weight measuring device 22. The aggregates entering the mixing container 20 can be accurately measured by the weight measuring device 22. The required amount of fine powder is calculated according to the specific weight of the aggregates. By setting the peristaltic pump, a certain amount of fine powder is sucked into the mixing container 20 through the second connecting pipe 19. In addition, the weight measuring device 22 can also calibrate the total weight; the water consumption is determined by the ratio, and the water consumption can be accurately controlled by the water control pump. When the material enters the mixing container 20 for mixing, the stirring shaft needs to rotate at high speed for mixing. At this time, the lifting mechanism 21 rises to lift the mixing container 20 away from the weight measuring device 22 to avoid inaccuracy caused by long-term high-speed rotation to the weight measuring device 22.

[0038] Embodiment 2: On the basis of Embodiment 1, in order to dehumidify and dry the aggregate, it also includes a circulating fan 24 and an electric heating pipe 25. The circulating fan 24 includes an air inlet 26 and an air outlet 27. The lower end of the electric heating pipe 25 is fixedly connected to the air outlet 27 of the circulating fan 24. A hot air outlet 28 is provided at the upper end of the side of the outer shell 3. The upper end of the electric heating pipe 25 is connected to the hot air outlet 28 by a pipe 29. The discharge pipe 17 is connected to an exhaust pipe 30. The end of the exhaust pipe 30 away from the discharge pipe 17 is fixedly connected to the air inlet 26.

[0039] When configuring the castable, the refractory aggregate needs to be dried to remove the moisture therein, so as to prevent the introduction of too much water vapor during the preparation of the castable and affect the performance of the castable. In the process of scooping up and scattering the aggregate for screening, the gas blown in by the circulating fan 24 enters the electric heating tube 25 through the air outlet 27 for heating, and then enters the outer shell 3 through the pipeline 29 and the hot air outlet 28, and enters the screening cylinder 4 through the primary screening hole 8. The scooped and scattered aggregate is in full contact with the hot air entering the screening cylinder 4, which can accelerate and evenly and comprehensively dry the aggregate. The dried gas is sucked in through the air inlet 26, and is used for circulation heating through the electric heating tube 25 to reduce energy waste.

[0040] Embodiment 3: On the basis of Embodiment 2, in order to cool the dried raw materials, the discharge pipe 17 is rotatably connected with a stirring shaft 31, and the stirring shaft 31 is fixedly connected with a discharge spiral blade 32, a scattering disc 33, and a stirring blade 34, the discharge spiral blade 32 is inside the discharge pipe 17, the scattering disc 33 is below the discharge pipe 17 and a discharge gap 35 is left between the discharge pipe 17, the stirring blade 34 is below the scattering disc 33, and the upper end surface of the scattering disc 33 is provided with a plurality of partitions 36 evenly distributed in a circumference;

[0041] The air outlet pipe 16 is connected to a branch pipe 47 , and the branch pipe 47 is vertically slidably connected to the mixing container 20 .

[0042] After drying, materials with too high temperature will also affect the performance of the castable, so the dried materials need to be cooled. The cooling is done by the cold air discharged by the air conditioner, or the gas discharged by the air compressor entering the interior of the mixing container 20 through the branch pipe 47 for cooling. The stirring shaft 31 is driven by a motor to rotate at a low speed. When the aggregate enters the discharge pipe 17, the aggregate is quantitatively discharged through the discharge spiral blades 32 and falls onto the scattering disc 33 through the discharge gap 35. When the scattering disc 33 rotates, the aggregate at its upper end can be evenly thrown out so that it can be evenly contacted with the cold air and cooled quickly. In addition, the stirring blades 34 can not only dry mix the aggregate and fine powder entering the mixing container 20, but also cool them during mixing.

[0043] Embodiment 4: On the basis of embodiment 1, in order to improve the screening efficiency of aggregate, the screening cylinder 4 includes an input cylinder 201, a vibrating cylinder 202 and an output cylinder 203, and the input cylinder 201 and the output cylinder 203 are rotatably connected to the outer shell 3, and a plurality of telescopic rods 37 evenly distributed around the axis of the vibrating cylinder 202 are fixedly connected between the vibrating cylinder 202 and the input cylinder 201 and the output cylinder 203, and the telescopic rod 37 includes a fixed rod and a sliding rod, and a first vibration spring is provided between the fixed rod and the sliding rod, so that the vibrating cylinder 202 can vibrate back and forth while rotating.

[0044] When the aggregate enters the screening cylinder 4 through the input cylinder 201, it will be continuously picked up and scattered by the first shoveling plate 9 for drying and screening, but the screening efficiency is low and the effect is not ideal. The aggregate entering the vibration cylinder 202 can accelerate the screening efficiency of the aggregate under the vibration of the vibration cylinder 202, and the screening result is more ideal, which further guarantees the performance of the later casting material. When the vibration cylinder 202 vibrates, the telescopic rod 37 continuously retracts and vibrates under the action of the first vibration spring.

[0045] Embodiment 5: On the basis of embodiment 4, in order to realize the rotation of the screening drum 4 and the vibration drum 202 generating vibrations, an end face cam 38 is fixedly connected inside the outer shell 3, and the right end face of the end face cam 38 is provided with continuously arranged protrusions and grooves to form an annular wavy surface 39, and a plurality of push rods 40 fixedly connected to the end face cam 38 and evenly distributed around the circumference are fixedly connected to the vibration drum 202, and the position of each push rod 40 corresponding to the protrusion or groove is the same.

[0046] When the screening drum 4 rotates, the push rod 40 on the vibration drum 202 cooperates with the end face cam 38. When the push rod 40 is at the raised portion of the end face cam 38 at the same time, the first vibration spring is stretched and the telescopic rod 37 is extended. When the push rod 40 moves toward the groove portion of the annular wave surface 39, the telescopic rod 37 is shortened under the pull of the first vibration spring, so that the vibration drum 202 can be continuously rotated back and forth.

[0047] Embodiment 6: On the basis of Embodiment 5, in order to reduce the aggregate mass of each vibration cylinder 202, enhance the vibration screening effect, and reduce the wear of parts, the vibration cylinder 202 is provided with a plurality of end face cams 38 in one-to-one correspondence, and a telescopic rod 37 is fixedly connected between every two adjacent vibration cylinders 202. The same material in one vibration cylinder 202 is changed to be distributed in multiple vibration cylinders 202, and they are respectively vibrated simultaneously with the end face cams 38, further enhancing the vibration screening effect.

[0048] In addition, in order to slow down the falling speed of the aggregate, make the aggregate stay in the screening drum 4 for a longer time for vibration screening and drying, and improve the screening and drying effects, the vibration drum 202 can be designed into a truncated cone shape.

[0049] Embodiment 7: On the basis of Embodiment 1, the discharge pipe 15 is connected with a material heating quick discharge component, and the material heating quick discharge component includes a material shell 41, and a rotating blade is rotatably connected inside the material shell 41, and the rotating blade includes a second rotating shaft 42 rotatably connected to the material shell 41, and a plurality of baffles 43 uniformly distributed in a circle are fixedly connected to the second rotating shaft 42, and a cell 44 is formed between every two adjacent baffles 43 and the material shell 41, and the air outlet pipe 16 is connected to the side of the material shell 41, and the blown gas can drive the rotating blade to rotate.

[0051] The material discharged by the peristaltic pump 12 enters the material shell 41. The rotating blades in the material shell 41 are driven by the air compressor to rotate. When the fine powder enters the cells 44 on the rotating blades, it is taken out by the rotating blades. During this period, the fine powder in the material shell 41 can be mixed and dried with the hot air discharged from the heating pipe 45.

[0052] Embodiment 9: Based on the embodiment 1, in order to facilitate the discharge of the material in the material storage chamber 3, the sliding rod and the fixed rod on the same set of telescopic rods 37 are respectively fixedly connected to an inclined annular sieving plate 46 through connecting pieces.
