Description

Technical Field

[0001] The invention relates to the technical field of measuring the sand content in tailings, and in particular to a device and method for analyzing and measuring the content of tailings in a machine-made sand plant. Background Art

[0002] Artificial sand is a common sand making method that is made by crushing and grinding large stones to form smaller sand and gravel to meet the needs of construction. However, since artificial sand is obtained by crushing large-particle stones, fine dust is easily generated during the crushing process, making it easy for tailings containing a certain amount of artificial sand to appear during the production process. A Chinese patent (publication number: CN 110372243 A) discloses a method for preparing machine-made sand, comprising the following steps: S1, cleaning: cleaning the block stone, tailings or abandoned building concrete used for producing machine-made sand with a cleaning liquid, and controlling the mud content of the cleaned block stone, tailings or abandoned building concrete to be 0%; S2, drying: draining the cleaned block stone, tailings or abandoned building concrete and drying them with hot air, so that the water content of the block stone, tailings or abandoned building concrete is less than 5%; S3, crushing: crushing the dried block stone, tailings or abandoned building concrete into sand particles; S4, screening: passing the crushed sand particles through a sieve, and controlling the fineness modulus of the sieved sand particles to be 3.0-3.6, and then re-crushing the unqualified sand particles so that the fineness modulus of the final crushed sand particles is 3.0-3.6, so as to obtain machine-made sand.

[0003] However, the existing treatment methods for machine-made sand tailings have some disadvantages, such as:

[0004] Since the production of machine-made sand is carried out by crushing stones, powdery debris is easily generated, and the powdery debris needs to be separated from the machine-made sand by washing. The tailings produced after the machine-made sand is washed also contain a certain proportion of usable machine-made sand. The determination of the machine-made sand content in the tailings is helpful for analyzing the deep processing value of the tailings. However, there is no analytical determination device for the machine-made sand content in the tailings in the prior art. Therefore, a machine-made sand tailings content analytical determination device is needed. Summary of the invention

[0005] In view of this, the purpose of the present invention is to propose an analytical measuring device and method for tailings content in an artificial sand plant, so as to solve the problem that when artificial sand is produced, it is carried out by crushing stones, so powdery debris is easily generated. The powdery debris needs to be separated from the artificial sand by flushing. The tailings produced after the artificial sand is washed still contain a certain proportion of usable artificial sand. The determination of the artificial sand content in the tailings is beneficial to analyzing the deep processing value of the tailings. However, there is no analytical measuring device for the artificial sand content in tailings in the prior art, so a device for analyzing and measuring the artificial sand tailings content is needed.

The sieve plate mechanism is arranged at the bottom of the aggregate bin, and is used to screen the tailings to be screened that enters the aggregate bin.

[0008] Furthermore, the screen plate mechanism includes a screen and a baffle. The screen plate mechanism arranged at the bottom of the two upper screening mechanisms adopts the screen, and the screen is used to screen the machine-made sand tailings. The screen plate mechanism arranged at the bottom of the bottom screening mechanism adopts the baffle, and the baffle is used to carry the machine-made sand tailings that have been screened.

[0009] Furthermore, three inclined guide pipes are evenly fixedly installed on the transmission rod, and the inclined guide pipes are inclined at the same angle. A transverse guide pipe is rotatably installed on the top of the inclined guide pipe, and the transverse guide pipe is connected with the inclined guide pipe. A connecting pipe is rotatably installed on one end of the transverse guide pipe away from the inclined guide pipe, and the transverse guide pipe is connected with the inclined guide pipe, and the connecting pipe is connected with the side wall of the aggregate bin at one end away from the transverse guide pipe.

[0010] Furthermore, a support plate is fixedly provided at the bottom of one end of the transverse guide pipe connected to the connecting pipe, and the support plate is used to support the connecting pipe. The connecting pipe maintains the same central axis with the transverse guide pipe through the support of the support plate.

[0011] Furthermore, three mounting rods are fixedly provided on the transmission rod, and a measuring box is fixedly connected to the other end of the mounting rod. The measuring box is fixedly installed on one side of the transmission rod through the mounting rod. The measuring box is arranged corresponding to one end of the bottom of the inclined guide pipe.

[0012] Furthermore, a first support ring is provided at the bottom of the transverse flow guide tube, a second support ring is provided between the transverse flow guide tubes, and a third support ring is provided at the top of the transverse flow guide tube. The three transverse flow guide tubes are respectively provided between the first support ring, the second support ring and the third support ring. The first support ring, the second support ring and the third support ring are all used to support and limit the rotation path of the transverse flow guide tube. The first support ring, the second support ring and the third support ring are all fixedly installed at the center of the mounting frame.

[0013] Furthermore, adjacent sides between the first support ring, the second support ring and the third support ring are provided with corrugated slide rails, and a limiting pulley is sleeved on the transverse guide tube.

[0034] A device for analyzing and measuring tailings content in a machine-made sand plant, comprising a mounting frame 101 and a motor seat 102, wherein the motor seat 102 is fixedly arranged at the bottom center of the mounting frame 101, a driving motor 103 is fixedly installed at the center of the upper surface of the motor seat 102 by bolts, the driving motor 103 is centrally arranged at the center of the mounting frame 101, a transmission rod 104 is fixedly installed at the power output end of the driving motor 103, the transmission rod 104 is vertically arranged at the center of the mounting frame 101, a screening mechanism 200 is fixedly installed on the side of the transmission rod 104, the driving motor 103 is used to drive the screening mechanism 200 to rotate through the transmission rod 104, the screening mechanism 200 is used to screen machine-made sand tailings, three screening mechanisms 200 are provided, and the three screening mechanisms 200 are vertically correspondingly arranged on the same axis;

[0035] The number of screening mechanisms 200 can be set according to the needs of the user, and the number is not necessarily limited to three. However, the number of screening mechanisms 200 cannot be less than three, because the screening process needs to screen out at least three materials, namely, stones with larger particle sizes, machine-made sand with normal particle sizes, and dust, from the machine-made sand tailings. Therefore, at least three screening mechanisms 200 need to be set to screen them. When it is necessary to distinguish between coarse sand and fine sand in the machine-made sand, it is necessary to add a screening mechanism 200 with a corresponding aperture.

[0036] The present invention can screen out machine-made sand and dust of different particle sizes by setting up three screening mechanisms 200 with different apertures, and then use the connecting pipe 303, the horizontal guide pipe 302 and the inclined guide pipe 301 to guide the screened materials to different metering devices 403 for weighing, so as to analyze the content of machine-made sand and dust of various particle sizes in the machine-made sand tailings, thereby determining the deep processing value of the machine-made sand tailings, so as to facilitate the recovery and reuse of the machine-made sand tailings.

[0037] Further, the screening mechanism 200 is provided with a collecting hopper 201, a collection bin 202 and a sieve plate mechanism 203, wherein the collecting hopper 201 is arranged through the top of the collection bin 202, the collecting hopper 201 is used to collect and guide the tailings to be screened into the collection bin 202, the sieve plate mechanism 203 is arranged at the bottom of the collection bin 202, and the sieve plate mechanism 203 is used to screen the tailings to be screened entering the collection bin 202; the sieve plate mechanism 203 includes a screen 2031 and a baffle 2032, the sieve plate mechanism 203 at the bottom of the two screening mechanisms 200 arranged at the top adopts the screen 2031, the screen 2031 is used to screen the machine-made sand tailings, and the sieve plate mechanism 203 at the bottom of the screening mechanism 200 arranged at the bottom adopts the baffle 2032, and the baffle 2032 is used to carry the machine-made sand tailings that have been screened;

[0038] The reason why the screening mechanism 200 needs to be provided with a collecting hopper 201 and a collecting bin 202 and use the sieve plate mechanism 203 at the bottom thereof for screening is that the screening mechanism 200 needs to rotate following the drive of the driving motor 103 and may also move downward. Therefore, the collecting hopper 201 and the collecting bin 202 are provided and the connection between the two is provided as a smaller channel, thereby preventing the screening mechanism 200 from being spilled from the top of the screening mechanism 200 during the rotation and up and down movement, thereby ensuring a more accurate determination of each component.

[0039] Among them, since the machine-made sand tailings may contain stones with larger particle sizes and powdered dust, the aperture of the screen 2301 at the bottom of the first screening mechanism 200 above needs to be set to only allow materials with normal machine-made sand particle sizes and dust materials to pass through, and the screen 2031 at the bottom of the second screening mechanism 200 in the middle is to filter the dust in the machine-made sand, thereby leaving the machine-made sand with appropriate particle size. Therefore, the screen 2301 at the bottom of the screening mechanism 200 is set to only allow dust to pass through. The bottom of the bottom screening mechanism 200 is set with a baffle 2302. Because the bottom screening mechanism receives dust, it does not need to be screened again. The baffle 2302 is used to retain the dust, and then it can be weighed to determine its content in the tailings.

[0040] Further, three inclined guide pipes 301 are evenly fixedly installed on the transmission rod 104, and the inclined guide pipes 301 are inclined at the same angle. A transverse guide pipe 302 is rotatably installed on the top of the inclined guide pipe 301, and the transverse guide pipe 302 is connected with the inclined guide pipe 301. A connecting pipe 303 is rotatably installed at one end of the transverse guide pipe 302 away from the inclined guide pipe 301, and the transverse guide pipe 302 is connected with the inclined guide pipe 301. The connecting pipe 303 is connected with the side wall of the collecting bin 202 at one end away from the transverse guide pipe 302.

[0041] The connection between the inclined flow guide tube 301 and the transmission rod 104 is set to a circular cavity, so that the transmission rod 104 will not block the passage inside the inclined flow guide tube 301. When the material flows through the inclined flow guide tube 301 and contacts the transmission rod 104, the material can bypass the transmission rod 104 and flow down from the cavities on both sides of the transmission rod 104, so that the transmission rod 104 cannot hinder the flow of the material.

[0042] Among them, the transverse guide pipe 302 is inserted into the inclined guide pipe 301, so that no matter how the transverse guide pipe 302 rotates, the material guided inside it will flow into the inclined guide pipe 301, so as to avoid the material being scattered and lost during the flow process, resulting in inaccurate component measurement; the connecting pipe 303 is also inserted into the transverse guide pipe 302, so that no matter how the connecting pipe 303 rotates around the transverse guide pipe 302, the material inside it can also enter the transverse guide pipe 302; and the end of the transverse guide pipe 302 connected to the inclined guide pipe 301 has a downward tilt angle, which is the minimum tilt angle that can make the material flow in the transverse guide pipe 302, so that the material can flow through the horizontal guide pipe 302 by its own gravity.

[0043] Furthermore, a support plate 700 is fixedly provided at the bottom of one end of the transverse flow guide pipe 302 connected to the connecting pipe 303, and the support plate 700 is used to support the connecting pipe 303. The connecting pipe 303 maintains a unified central axis with the transverse flow guide pipe 302 through the support of the support plate 700;

[0044] Among them, since one end of the connecting pipe 303 is connected to the screening mechanism 200, the screening mechanism 200 has a certain gravity. If the support plate 700 is not set at the bottom of the connecting pipe 303, the end of the connecting pipe 303 connected to the screening mechanism 200 will tilt downward, thereby causing the screened material to spill or resulting in poor screening effect.

[0045] Further, three mounting rods 401 are fixedly provided on the transmission rod 104, and a measuring box 402 is fixedly connected to the other end of the mounting rod 401, and the measuring box 402 is fixedly installed on one side of the transmission rod 104 through the mounting rod 401. The measuring box 402 is arranged corresponding to one end of the bottom of the inclined guide pipe 301, and a meter 403 is placed inside the measuring box 402, and the meter 403 is used to receive and measure the machine-made sand tailings flowing out of the inclined guide pipe 301. An observation window 404 is opened on one side of the measuring box 402, and the observation window 404 is used to observe the reading of the meter 403, and the driving motor 103 is used to drive the measuring box 402 and the meter 403 inside it to rotate through the mounting rod 401;

[0046] Among them, the measuring device 403 can be an electronic scale, and the box on the top of the measuring device 403 for carrying the material to be weighed is deeper, so that the material will not be rotated and thrown out after entering the box. At the same time, the box for carrying the material to be weighed can be removed, so that after weighing is completed, the box can be removed and the material inside it can be dumped to facilitate the next use of the device.

[0047] Further, a first support ring 501 is provided at the bottom of the transverse flow guide tube 302, a second support ring 502 is provided between the transverse flow guide tubes 302, and a third support ring 503 is provided at the top of the transverse flow guide tube 302. The three transverse flow guide tubes 302 are respectively arranged between the first support ring 501, the second support ring 502 and the third support ring 503. The first support ring 501, the second support ring 502 and the third support ring 503 are all used to support and limit the rotation path of the transverse flow guide tube 302. The first support ring 501, the second support ring 502 and the third support ring 503 are all fixedly mounted at the center of the mounting frame 101; the adjacent sides of the first support ring 501, the second support ring 502 and the third support ring 503 are all provided with corrugated slide rails 601, and the transverse guide tube 302 is sleeved with a limiting pulley 602, and the limiting pulley 602 is arranged corresponding to the corrugated slide rail 601, and the transverse guide tube 302 slides on the corrugated slide rail 601 through the limiting pulley 602;

[0048] Among them, a corrugated groove is formed between two adjacent corrugated slide rails 601, and the transverse guide pipe 302 can slide along the corrugated groove through the limiting pulley 602. The transverse guide pipe 302 can drive the screening mechanism 200 to move up and down during the sliding process along the corrugated groove. The process of the screening mechanism 200 moving up and down can be used to speed up the screening of materials.

[0049] A method for using a device for analyzing and measuring tailings content in a machine-made sand plant comprises the following steps:

[0050] S1, tailings screening;

[0051] Weigh the machine-made sand tailings to be measured by unit mass, and put the tailings into the topmost screening mechanism 200. After the tailings enter the collecting bin 202 through the collecting hopper 201, the tailings screened by the sieve plate mechanism 203 at the bottom fall into the next screening mechanism 200. By reducing the apertures of the sieve plate mechanisms 203 of different screening mechanisms 200 from top to bottom, the particle size of the machine-made sand screened by the screening mechanism 200 from top to bottom gradually decreases, thereby realizing screening of materials with different particle sizes in the machine-made sand tailings;

[0052] S2, determination of tailings mud content;

[0053] The materials of different particle sizes screened out inside each layer of the screening mechanism 200 are respectively directed to the meter 403 through the connecting pipe 303, the transverse guide pipe 302 and the inclined guide pipe 301, and then the mass of the materials of different particle sizes screened out is read through the observation window 404, thereby calculating the proportion of materials of different particle sizes in the machine-made sand tailings.

[0054] In summary, when in use, take a unit mass of machine-made sand tailings and put the machine-made sand tailings into the topmost screening mechanism 200. Since the machine-made sand tailings may contain stones with larger particle sizes and powdered dust, the aperture of the screen 2301 at the bottom of the first screening mechanism 200 above needs to be set to only allow materials with normal machine-made sand particle sizes and dust materials to pass through, and the screen 2031 at the bottom of the second screening mechanism 200 in the middle is to filter the dust in the machine-made sand, thereby leaving the machine-made sand with appropriate particle sizes. Therefore, the screen 2301 at the bottom of the screening mechanism 200 is set to only allow dust to pass through, and the bottom screening mechanism The baffle 2302 is arranged at the bottom of the structure 200, because the bottommost screening mechanism receives only dust, which does not need to be screened again. The baffle 2302 is used to leave the dust, and then the dust can be weighed to determine its content in the tailings. After the screening is completed, the user pushes up the three screening mechanisms 200 respectively, so that the materials inside the three screening mechanisms 200 fall onto the meter 402 through the connecting pipe 303, the transverse guide pipe 302 and the inclined guide pipe 301 respectively. The user can calculate the content of available machine-made sand in the machine-made sand tailings by observing the mass of each component, and then judge whether the machine-made sand tailings has the value of recycling and reuse.

[0055] The present invention can screen out machine-made sand and dust of different particle sizes by setting up three screening mechanisms 200 with different apertures, and then use the connecting pipe 303, the horizontal guide pipe 302 and the inclined guide pipe 301 to guide the screened materials to different metering devices 403 for weighing, so as to analyze the content of machine-made sand and dust of various particle sizes in the machine-made sand tailings, thereby determining the deep processing value of the machine-made sand tailings, so as to facilitate the recovery and reuse of the machine-made sand tailings.
