Description

Technical Field

[0001] The present application relates to the field of ceramsite production, and in particular to a high-precision batching device for ceramsite raw materials. Background Art

[0002] Clay is a kind of ceramic particles, and the shape of ceramsite varies due to different processes. Its surface is a hard shell, which is ceramic or glazed, has the function of water insulation and air retention, and gives the ceramsite higher strength.

[0003] Clay ceramsite is a kind of artificial particles with ceramic texture, which is widely used in the preparation of high-rise building structural concrete. One of its main raw materials is mud, which is mainly made by mixing clay, sludge filter cake, water, sludge and powder. At present, clay mixer is mainly used for mixing ingredients. The accuracy of ingredients is very important. Traditional metering methods mostly use metering buckets for weighing. However, due to the high viscosity of clay and sludge filter cake, it is impossible to use metering buckets for weighing, which leads to inconvenience in mixing ingredients. Summary of the invention

[0004] In order to improve the problem of inconvenient batching, the present application provides a high-precision batching device for ceramsite raw materials.

[0005] The present application provides a high-precision batching device for ceramsite raw materials using the following technical solutions:

[0006] A high-precision batching device for ceramsite raw materials comprises a clay mixer and a feeding device, wherein the feeding device comprises a first feeding mechanism for conveying clay and sludge filter cakes, a second feeding mechanism for conveying sludge, a third feeding mechanism for conveying powder, and a fourth feeding mechanism for conveying water, wherein the second feeding mechanism and the fourth feeding mechanism are provided with flow meters, the third feeding mechanism is provided with a metering bucket, and the first feeding mechanism comprises a belt scale, which is arranged obliquely and has one high end located at the feed inlet of the clay mixer.

[0007] In the actual batching process, the sticky clay and sludge filter cake raw materials are transported and loaded through a belt scale, and weighed at the same time. For the sludge and water with lower concentrations, due to their good fluidity, accurate quantification is achieved with the help of a flow meter during the transportation process. The powder is transported to the metering barrel by a spiral conveyor, weighed, and then dropped into the clay mixer to ensure quantification, thereby realizing automatic loading of each raw material. At the same time, each raw material is quantified in a corresponding appropriate manner, which makes batching convenient and effectively improves the batching accuracy.

[0008] Preferably, the second feeding mechanism and the fourth feeding mechanism both include a delivery pipe and a pump body, the flow meter is arranged on the delivery pipe and a stop valve is arranged on the delivery pipe, and the flow meter is located at the end of the delivery pipe.

[0009] The pump body is used to provide the conveying power. The stop valve can be closed in time to stop the delivery when the flow reaches the required amount. Setting the flow meter at the end of the delivery pipe can achieve more accurate measurement.

[0010] Preferably, the third feeding mechanism comprises a screw conveyor, a discharge end of the screw conveyor is connected to a metering barrel, and a discharge port of the metering barrel is connected to a clay mixer.

[0011] The dust is transported by spiral conveyor with good sealing performance, and it is not easy for dust to affect the environment. The dust is transported to the metering bucket for weighing. When the required amount is reached, the conveying is stopped, and then the discharge port of the metering bucket is opened. The powder can fall into the clay mixer in a quantitative manner, ensuring the quantitative accuracy of the powder feeding.

[0012] Preferably, the upper end of the belt scale is located above the feed inlet of the clay mixer.

[0013] By such arrangement, after the clay is conveyed to the end of the belt scale, it can fall well into the feed port of the clay mixer, and the clay can be well prevented from falling outside the clay feed port when falling.

[0014] Preferably, the belt scale includes a frame and a belt, the belt includes a loaded upper section and an unloaded lower section, a scraper abutting against the belt is obliquely arranged at the corresponding feed port of the clay mixer, and the top of the scraper is inclined toward the middle of the corresponding feed port of the clay mixer and abuts against the surface of the lower section of the belt.

[0015] Since clay is very sticky, during the conveying process, after the belt transports the material to the end and drops it into the clay mixer, some clay will still adhere to the belt, resulting in a smaller actual amount of clay added. By setting the scraper, the scraper can scrape off the soil adhering to the belt when the belt moves, further improving the accuracy of feeding; in addition, the scraper is set inclined toward the middle of the feed port so that the scraped soil is not easy to fall on the scraper, and can fall directly into the clay mixer.

[0016] Preferably, the side of the scraper away from the belt is hinged to the clay mixer, and the clay mixer is provided with a driving motor for driving the scraper to flip.

[0017] The scraper is hinged and can be turned over, so that firstly the angle of the scraper can be adjusted, that is, the contact position with the belt can be adjusted by turning over, and even the belt can be further tensioned when it is not fully tensioned.

[0018] Preferably, a convex portion for supporting the scraper away from the hinged side is provided inside the feed inlet of the clay mixer, and the feed inlet of the clay mixer is closed when the scraper is turned over and abuts against the convex portion.

[0019] With this arrangement, after loading is completed, the scraper is driven to flip to a horizontal state. At this time, the scraper can close the feed port, which is more convenient for subsequent mixing work, realizes the multi-purpose use of the scraper, and has better practicality.

[0020] Preferably, the scraper includes an outer frame plate and an inner plate, one side of the inner plate is hinged to the outer frame plate, the outer frame plate is provided with a through groove adapted to the inner plate, and a locking member is provided at the connection between the inner plate and the outer frame plate to keep the inner plate away from the hinged side and abut against the lower section of the belt.

[0021] The scraper is arranged as an outer frame plate and an inner plate hinged to each other, so as to realize the purpose of multi-stage scraping and achieve a better scraping effect. With the help of the locking piece, the abutment effect between the inner plate and the lower section of the belt can be well maintained, the scraping state can be well maintained, and the material scraped off by the inner plate can fall through the through groove without being blocked by the outer frame plate.

[0022] Preferably, the locking member comprises a torsion spring, one end of which is fixed to the inner plate, and the other end of which is fixed to the outer frame plate.

[0023] The torsion spring provides a turning force for the inner plate. It has a simple structure and can well maintain the stability of the inner plate and the belt, and keep the outer frame plate and the inner plate in a good separation state. In this way, as the resistance of the adhering material on the inner plate increases during the scraping process, the elastic force of the torsion spring also increases accordingly, and the scraping effect can change in accordance with the size of the resistance, thereby achieving a better scraping effect.

[0024] Preferably, when the outer frame plate is turned over and abuts against the convex portion, the gravity of the inner plate overcomes the elastic force of the torsion spring and turns over to cooperate with the through groove of the outer frame.

[0025] In this way, when the scraper and the convex part abut against the feed port of the closed clay mixer, the inner plate cooperates with the through groove under its own gravity, that is, the inner plate and the outer frame plate form an integral scraper, and the through groove is also blocked by the inner plate, which plays a good sealing role. When the driving motor drives the scraper to turn up, due to the gradual inclination of the scraper, it is estimated that the force of the inner plate in the vertical direction gradually decreases, and then the elastic force of the torsion spring gradually causes the inner plate to flip over from the through groove and one side gradually abuts against the belt, so as to achieve the purpose of double scraping.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The sticky clay and sludge filter cake are transported and weighed by a belt scale, the sludge and water are quantified by a flow meter, and the dust is transported by a spiral and weighed with a metering bucket to ensure the accuracy of the mixed amount of each raw material and the convenience of batching;

[0028] 2. The flow meter and metering barrel are both set at the end of the conveying, which can effectively improve the accuracy of batching;

[0029] 3. By setting up a scraper, the material adhering to the belt can be effectively scraped off, further improving the accuracy of material input. The angle of the scraper can be adjusted according to actual needs, and the feed port of the clay mixer can be closed after the scraper is flipped, which is more practical.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-3 This application is described in further detail.

[0036] The embodiment of the present application discloses a high-precision batching device for ceramsite raw materials.

[0037] Example 1

[0038] Reference Figure 1A high-precision batching device for ceramsite raw materials comprises a clay mixer 1 and a first feeding mechanism, a second feeding mechanism, a third feeding mechanism and a fourth feeding mechanism for conveying raw materials, wherein the clay mixer 1 is a high-speed inclined clay mixer, the clay mixer 1 comprises a cylinder 2, the cylinder 2 is inclined, a stirring paddle 3 is arranged in the cylinder 2, and a feed inlet is arranged at the top of the cylinder 2, and a discharge port is arranged at the bottom of the clay mixer 1; by conveying each raw material into the cylinder 2, and then realizing good stirring through the synchronous rotation of the cylinder 2 and the stirring paddle 3, the mixture is discharged through the discharge port after the stirring is completed.

[0039] like Figure 1 and Figure 2 As shown, there are two first feeding mechanisms and they are symmetrically arranged on both sides of the clay mixer 1. The two first feeding mechanisms are used to transport clay and sludge filter cake respectively. The first feeding mechanism includes a belt scale 4. The belt scale 4 includes a frame 41, a belt 42 and a synchronous wheel 43. The belt scale 4 is tilted and one end at the high end is located directly above the feed port of the clay mixer 1. The lower end is connected to a box feeder 5, so that the clay and sludge filter cake are placed on the belt 42 from the bottom of the belt scale 4, and then transported to the feed port of the clay mixer 1 during the movement of the belt 42. During this period, accurate weighing is achieved with the help of the belt scale 4, which effectively solves the problem of difficulty in quantitative feeding of existing viscous raw materials such as clay and sludge filter cake. In actual use, the clay and sludge filter cake are de-stoned by a de-stoner before feeding.

[0040] like Figure 1 As shown, the second feeding mechanism is used to transport sludge, wherein the sludge has a relatively thin concentration and good fluidity. The second feeding mechanism includes a conveying pipe 6 and a pump body 7. The pump body 7 is a sludge pump. The pump body 7 is connected to the conveying pipe 6. A sludge bucket 8 for storing sludge is connected to one end of the conveying pipe 6, and the other end is connected to the clay mixer 1. The pump body 7 provides conveying power to pump the sludge in the sludge bucket 8 into the clay mixer 1 to complete the loading. A flow meter 9 and a stop valve 10 are arranged at the end of the conveying pipe 6 near the clay mixer 1. The flow meter 9 is used to accurately determine the conveying amount to ensure the accuracy of the conveyed material amount. The stop valve 10 is closed in time when the corresponding amount is reached.

[0041] like Figure 1As shown, the third feeding mechanism is used to convey powder, and the third feeding mechanism includes a screw conveyor 11, and the discharge end of the screw conveyor 11 is connected to a metering barrel 12, the metering barrel 12 is located in the clay mixer 1, and the discharge port of the metering barrel 12 is connected to the inside of the clay mixer 1, and the feed port of the screw conveyor 11 is connected to the ash barrel 13, so that the powder stored in the ash barrel 13 is spirally conveyed to the metering barrel 12 by the screw conveyor 11, and the conveying is stopped after the required amount is reached in the metering barrel 12, and then the discharge port of the metering barrel 12 is opened, and the powder falls into the clay mixer 1 to complete quantitative and accurate feeding. The spiral conveying method has good sealing performance, which can effectively reduce the phenomenon of dust, making the external environment cleaner and more environmentally friendly.

[0042] like Figure 1 As shown, the fourth feeding mechanism is used to transport water, which also includes a delivery pipe 6 and a pump body 7. A water tank 14 is arranged at the head end of the delivery pipe 6, and the end of the delivery pipe 6 is connected to the interior of the clay mixer 1. A flow meter 9 and a stop valve 10 are arranged at the end of the delivery pipe 6 near the clay mixer 1. When in use, the flow meter 9 is used to accurately control the quantitative delivery of water. When the required amount of water is reached, the stop valve 10 is closed in time. In addition, the flow meter 9 is arranged at the end of the delivery pipe 6 for higher accuracy.

[0043] Therefore, different methods are used for loading and weighing different materials to ensure that the raw materials can be loaded conveniently and weighed accurately, ensuring the accuracy and precision of the ingredients.

[0044] like Figure 1 As shown, a conveyor belt 15 for feeding is arranged at the bottom of the discharge port of the clay mixer 1, and a twin-shaft mixer 16 is connected to the conveying end of the conveyor belt 15. The mixed raw materials are discharged from the discharge port of the clay mixer 1 and fall onto the conveyor belt 15, and then transported to the twin-shaft mixer 16 for stirring. After the stirring is completed, the raw materials are transported to the ceramsite production workshop for use.

[0045] The implementation principle of Example 1 is as follows: first, the clay mixer 1 is turned on, and the stirring paddle 3 is continuously rotated rapidly. Then, the clay and the sludge filter cake that have been destoned are continuously transported to the clay mixer 1 through the belt scale 4, and the powder is continuously transported to the clay mixer 1 through the screw conveyor 11. Water and sludge are continuously transported to the clay mixer 1 under the action of the pump body 7 and the conveying pipe 6. Each material is continuously stirred and mixed in the clay mixer 1 until each material is transported to the required quantity and then the conveying is stopped. After the stirring is completed, the stirring speed of the stirring paddle 3 is slowed down, and then the material is continuously discharged from the discharge port of the clay mixer 1, and is transported to the double-shaft mixer 16 under the action of the belt conveyor 15 for further stirring, and finally transported to the ceramsite production workshop for use.

[0046] Example 2

[0047] Reference Figure 3 , a high-precision batching device for ceramsite raw materials, the main difference between this embodiment and embodiment 1 is that the feed port of the clay mixer 1 is square and a scraper 17 is arranged on its inner wall, the scraper 17 is arranged obliquely toward the middle of the feed port of the clay mixer 1, the belt 42 of the belt scale 4 includes a loaded upper section and an unloaded lower section, and one end of the scraper 17 at the inclined height abuts against the surface of the lower section of the belt 42, so that the clay adhered to the belt 42 during the time of use can be scraped off by the scraper 17 and enter the clay mixer 1, ensuring the accuracy of the feeding, and the clay scraped off by the inclined scraper 17 is not easy to fall on the scraper 17, and can fall directly into the clay mixer 1.

[0048] like Figure 3 As shown, the side of the scraper 17 away from the belt 42 is hinged to the inner wall of the feed inlet of the clay mixer 1, that is, protruding columns 18 extend from both ends of the scraper 17 and are inserted into the inner wall of the feed inlet of the clay mixer 1 to achieve hinge connection. At the same time, a driving motor 19 for driving the scraper 17 to flip is provided on the clay mixer 1, and the output shaft of the driving motor 19 is connected to the protruding column 18; in this way, the inclination angle of the scraper 17 can be adjusted, and the belt 42 can be tightened while scraping the material; in addition, at the feed inlet of the clay mixer 1 A convex portion 20 is provided on the inner wall of the material port, and the convex portion 20 is used to support the scraper 17 away from the hinged side. After the feeding is completed, the scraper 17 is driven by the driving motor 19 to flip to a horizontal state until it abuts against the convex portion 20. At this time, the scraper 17 is in a horizontal state and closes the feeding port of the clay mixer 1, which is convenient for the subsequent continuous mixing and stirring of the raw materials inside. In addition, the scraper 17 generates vibration at the moment it hits the convex portion 20, which is convenient for shaking off the material remaining on the scraper 17, thereby realizing the multi-purpose of the scraper 17 and better practicality.

[0049] like Figure 3 and Figure 4As shown, the scraper 17 includes an outer frame plate 171 and an inner plate 172, a through slot 173 adapted to the inner plate 172 is provided on the outer frame plate 171, one side of the inner plate 172 is hinged to the outer frame plate 171, that is, the inner plate 172 can be flipped relative to the outer frame plate 171, and a locking member for keeping the inner plate 172 flipped out of the through slot 173 is provided at the hinge of the inner plate 172 and the outer frame plate 171, and the locking member includes a torsion spring (not shown in the figure), one end of the torsion spring is fixed to the inner plate 172, and the other end is fixed to the inner plate 172. The outer frame plate 171 is fixed, so that in actual use, the ends of the inner plate 172 and the outer frame plate 171 are both in contact with the belt 42, which can achieve a double scraping effect and achieve a better scraping effect; corresponding through holes 174 are opened on the inner plate 172 and the outer frame plate 171. When only one level of scraping is required, the inner plate 172 can be located in the through groove 173 of the outer frame plate 171 by inserting a pin into the through hole 174. At this time, the scraper 17 is a whole, which enables the scraper 17 to be used in multiple occasions and has better applicability.

[0050] The inner plate 172 has an acute-angled tip on one side away from the hinge, which can improve the scraping effect of the inner plate 172 on the one hand, and can also be turned in and out of the through groove 173 well on the other hand, without getting stuck; when the scraper 17 is in the double scraping state, after the material is loaded, the drive motor 19 drives the scraper 17 to flip to a horizontal state, and the gravity of the inner plate 172 can overcome the force of the torsion spring to flip and sink into the through groove 173, so that the feed port of the clay mixer 1 can be well closed; and when the scraper 17 is turned up and is in the scraping state, because the gravity of the inner plate 172 gradually decreases in the vertical direction at this time, the inner plate 172 will gradually flip out of the through groove 173 under the action of the torsion spring and abut against the belt 42, stably achieving the double scraping effect, and the operation is simple, and there is no need to think about special operation during the period.

[0051] The implementation principle of Example 2 is as follows: first, the clay mixer 1 is turned on, and the stirring paddle 3 rotates continuously and rapidly. Then, the clay and sludge filter cake that have been de-stoned are continuously transported to the clay mixer 1 through the belt scale 4, and the powder is continuously transported to the clay mixer 1 through the screw conveyor 11. Water and sludge are continuously transported to the clay mixer 1 under the action of the pump body 7 and the conveying pipe 6. Each material is continuously stirred and mixed in the clay mixer 1, wherein the belt scale 4 drives the motor 19 to drive the scraper 17 to flip to abut against the belt 42 during the feeding process to achieve scraping, and the conveying is stopped after each material is transported to the required quantitative amount. The driving motor 19 drives the scraper 17 to flip to the horizontal closed clay mixer 1 inlet, and then the stirring paddle 3 continues to stir. After the stirring and mixing is completed, the stirring speed slows down, and then the material is continuously discharged from the discharge port of the clay mixer 1, and is transported to the double-shaft mixer 16 under the action of the belt conveyor 15 for further stirring, and finally transported to the ceramsite production workshop for use.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
