[0034] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings.
[0035] Reference Figure 1 to Figure 2 The present invention provides a dust removal type dry mortar mixing system, comprising:
[0036] Rack 100;
[0037] The stirring device 200 is disposed on the frame 100, and the stirring device 200 is provided with a main feed inlet 210, an auxiliary feed inlet 220 and a discharge port 230;
[0038] The packing device 300 is located below the stirring device 200, and the packing device 300 is connected to the discharge port 230. The packing device 300 is used to pack the dry mortar;
[0039] The recovery device 400 includes a dust removal component 410 and a powder storage container 420. The dust removal component 410 includes a first dust removal pipe 411, a second dust removal pipe 412 and a dust collector 413. One end of the first dust removal pipe 411 faces the main feeding port 210, and the other end of the first dust removal pipe 411 is connected to the dust collector 413. One end of the second dust removal pipe 412 faces the packaging device 300, and the other end of the second dust removal pipe 412 is connected to the dust collector 413. The powder storage container 420 is located below the stirring device 200. The first discharge port 514 of the dust collector 413 is connected to the powder storage container 420. The dust collector 413 is used to recover the dust in the first dust removal pipe 411 and the second dust removal pipe 412 into the powder storage container 420.
[0040] The lifting device 700 has one end connected to the powder storage container 420 and the other end connected to the auxiliary material inlet 220 . The lifting device 700 is used to transport the dust in the powder storage container 420 to the auxiliary material inlet 220 .
[0041] Among them, a stirring blade and a driving motor can be provided in the stirring device 200, and the driving motor can drive the stirring blade to rotate. The main inlet and the auxiliary feed port 220 are both arranged above the stirring device 200, and the discharge port 230 is arranged below the stirring device 200.
[0042] It can be understood that, by providing the stirring device 200 and the packaging device 300, the stirring device 200 can transport the stirred dry mortar to the packaging device 300 through the discharge port 230 for packaging processing, and by providing the dust removal component 410 including the first dust removal pipeline 411, the second dust removal pipeline 412 and the dust collector 413, since one end of the first dust removal pipeline 411 is toward the main feed port 210 of the stirring device 200, and one end of the second dust removal pipeline 412 is toward the packaging device 300, under the action of the dust collector 413, when the material of the dry mortar is added, the dust overflowing from the main feed port 210 can be recovered into the powder storage container 420 through the first dust removal pipeline 411, and when the dry mortar is packaged, the dust can be collected from the packaging device 300. The overflowed dust is recovered into the powder storage container 420 through the second dust removal pipe 412, thereby realizing multi-point dust removal at the main feeding port 210 and the packaging device 300, which can improve the dust removal effect, and by arranging a lifting device 700, one end of the lifting device 700 is connected to the powder storage container 420 located below, and the other end of the lifting device 700 is connected to the stirring device 200 located on the frame 100. When the material of the dry mortar is added, the dust recovered in the powder storage container 420 can be transported to the auxiliary feeding port 220 of the stirring device 200 through the lifting device 700, and the recovered dust can be subsequently stirred in the stirring device 200, so that the recovered dust can be reused while eliminating the need for manual transportation of the recovered dust, which can reduce labor costs and improve production efficiency.
[0043] In specific practice, the main feed port 210 can be connected to a storage bin, and the material of the dry mortar can be stored in the storage bin, and the material of the dry mortar can be provided to the stirring device 200 through the storage bin.
[0044] Among them, a flexible connecting pipe can be connected between the main feed port 210 and the storage bin, a flexible connecting pipe can be connected between the auxiliary feed port 220 and the lifting device 700, and a flexible connecting pipe can be connected between the packaging device 300 and the discharge port 230, which can reduce the adverse effects caused by the vibration of the stirring device 200.
[0045] Specifically, the stirring device 200 can be provided with a dust cover, the main feed port 210 is located in the dust cover, and one end of the first dust removal pipe 411 is also located in the dust cover. Under the barrier effect of the dust cover, dust can be prevented from overflowing into the production workshop.
[0046] In addition, refer to Figure 1 and Figure 3In some embodiments of the utility model, a container cavity 600 is formed in the powder storage container 420, and a vertical partition 630 is arranged in the powder storage container 420. The partition 630 divides the container cavity 600 into a storage cavity 610 and a discharge cavity 620. The storage cavity 610 is provided with a first cavity 611 and a second cavity 612 from top to bottom. The first cavity 611 and the second cavity 612 are separated by a first filter 640. The partition 630 is provided with a first electric gate valve 631 and a second electric gate valve 632. The first electric gate valve 631 is used to connect or block the first cavity 611 and the discharge cavity 620, and the second electric gate valve 632 is used to connect or block the second cavity 612 and the discharge cavity 620. The first discharge port 514 of the dust collector 413 is connected to the first cavity 611, and one end of the lifting device 700 is connected to the discharge cavity 620.
[0047] It can be understood that by arranging the partition 630 in the powder storage container 420, a storage cavity 610 and a discharge cavity 620 can be formed in the powder storage container 420, wherein the storage cavity 610 is a cavity connected to the first discharge port 514 of the dust collector 413, and the discharge cavity 620 is a cavity connected to the lifting device 700. Due to the action of the dust collector 413, the dust overflowing from the main feed port 210 can be recovered into the powder storage container 420 through the first dust removal pipeline 411, and the dust from the packaging can be recovered into the powder storage container 420. The dust overflowing from the device 300 is recovered into the powder storage container 420 through the second dust removal pipe 412, while the dust overflowing from the main feed inlet 210 is usually the material of the unmixed dry mortar, and the particle size of the unmixed dry mortar is usually larger. The dust overflowing from the packaging device 300 is usually the mixed dry mortar, and the particle size of the mixed dry mortar is usually smaller. Therefore, dust of different particle sizes is stored in the storage cavity 610, and the particle size may refer to the average diameter of the dust.
[0048] Based on this, the storage chamber 610 is divided into two upper and lower sub-chambers by the first filter net 640, the upper sub-chamber in the storage chamber 610 is used as the first chamber 611, and the lower sub-chamber in the storage chamber 610 is used as the second chamber 612. Under the screening effect of the first filter net 640, dust with larger particle size can be stored in the first chamber 611, and dust with smaller particle size can be stored in the second chamber 612; by arranging the first electric gate valve 631 and the second electric gate valve 632 on the partition plate 630, the separate reuse of dust with different particle sizes can be achieved. Specifically, for the separate reuse of dust with larger particle size, the first electric gate valve 631 can be controlled to be opened, and the second electric gate valve 632 can be controlled to be closed, so that the dust with larger particle size in the first chamber 611 can be discharged through the first electric gate valve 631 The dust with larger particle size in the discharge chamber 620 is placed in the discharge chamber 620, and then the lifting device 700 is used to transport the dust with larger particle size in the discharge chamber 620 to the auxiliary feed port 220; for the dust with smaller particle size, it can be reused separately by controlling the second electric gate valve 632 to open and the first electric gate valve 631 to close, so that the dust with smaller particle size in the first chamber 611 can be discharged into the discharge chamber 620 through the second electric gate valve 632, and then the dust with smaller particle size in the discharge chamber 620 is transported to the auxiliary feed port 220 through the lifting device 700; subsequently, the recovered dust with different particle sizes can be treated in a targeted manner in the stirring device 200. For example, after adding dust with larger particle size, the dust needs to be stirred for a longer time, and after adding dust with smaller particle size, the dust needs to be stirred for a shorter time. Through targeted treatment, the production efficiency can be improved.
[0049] It should be noted that the upper wall, lower wall, front wall and rear wall in the powder storage container 420 are respectively fitted with the side walls corresponding to the partition 630, so that the storage cavity 610 is located on one side of the partition 630 and the discharge cavity 620 is located on the other side of the partition 630.
[0050] It is worth noting that when the total amount of dust in the powder storage container 420 is small, the first electric gate valve 631 and the second electric gate valve 632 can also be controlled to open at the same time to increase the delivery amount of the recovered dust by the lifting device 700 and improve production efficiency.
[0051] In addition, refer to Figure 4 , further comprising a vibrator 810 , which is disposed on the first filter net 640 , and is used to vibrate the first filter net 640 .
[0052] It can be understood that when the dust collector 413 discharges dust of different particle sizes into the powder storage container 420 through the first discharge port 514, the dust of different particle sizes will be first stored in the first cavity 611, and the first filter 640 can screen the dust in the first cavity 611, store the dust with larger particle size in the first cavity 611, and store the dust with smaller particle size in the second cavity 612. By arranging a vibrator 810 on the first filter 640, after the vibrator 810 is started, the first filter 640 can be vibrated, thereby speeding up the screening process of dust of different particle sizes.
[0053] In addition, refer to Figure 4 The height of the first filter screen 640 on the side away from the partition 630 is greater than the height of the first filter screen 640 on the side close to the partition 630, the height of the bottom of the storage cavity 610 is greater than the height of the bottom of the discharge cavity 620, and the bottom of the storage cavity 610 is parallel to the first filter screen 640.
[0054] It can be understood that since the height of the side of the first filter 640 away from the partition 630 is greater than the height of the side of the first filter 640 close to the partition 630, the first filter 640 is inclined to facilitate the dust in the first cavity 611 to be effectively discharged from the first electric gate valve 631; since the height of the bottom of the storage cavity 610 is greater than the height of the bottom of the discharge cavity 620, and the bottom of the storage cavity 610 is parallel to the first filter 640, the bottom of the storage cavity 610 is also inclined to facilitate the dust in the second cavity 612 to be effectively discharged from the second electric gate valve 632.
[0055] In addition, refer to Figure 5 , also includes a controller 900, and the lifting device 700, the first electric gate valve 631 and the second electric gate valve 632 are electrically connected to the controller 900 respectively.
[0056] It can be understood that by setting up the controller 900, under the action of the controller 900, the lifting device 700, the first electric gate valve 631 and the second electric gate valve 632 can be automatically controlled. For example, while controlling the first electric gate valve 631 to open, the second electric gate valve 632 is controlled to close, and the lifting device 700 is controlled to transport the dust discharged from the first cavity 611 to the auxiliary feed port 220; for another example, while controlling the second electric gate valve 632 to open, the first electric gate valve 631 is controlled to close, and the lifting device 700 is controlled to transport the dust discharged from the second cavity 612 to the auxiliary feed port 220.
[0057] In addition, refer to Figure 6, also includes a pressure sensor 820 and an alarm 830, the pressure sensor 820 is arranged at the bottom of the powder storage container 420, and the pressure sensor 820 and the alarm 830 are electrically connected to the controller 900 respectively.
[0058] It can be understood that by setting up the pressure sensor 820, the pressure information of the powder storage container 420 can be detected in real time, which is equivalent to being able to determine the total amount of dust stored in the powder storage container 420. When the total amount of dust stored in the powder storage container 420 is too large, an alarm can be sounded through the alarm 830 to promptly notify the staff to take relevant measures.
[0059] In addition, refer to Figure 7 The dust collector 413 includes a first negative pressure chamber 510 and a first negative pressure machine 520. The first negative pressure chamber 510 is provided with a first opening 511, a second opening 512 and a third opening 513. A first discharge port 514 is provided at the bottom of the first negative pressure chamber 510. The first discharge port 514 is provided with a third electric gate valve 516. The other end of the first dust removal duct 411 is connected to the first opening 511, and the other end of the second dust removal duct 412 is connected to the second opening 512. The air inlet of the first negative pressure machine 520 is connected to the third opening 513, and a second filter screen 515 is provided at the third opening 513.
[0060] It can be understood that the dust collector 413 includes a first negative pressure chamber 510 and a first negative pressure machine 520. Since the air inlet of the first negative pressure machine 520 is connected to the third opening 513 of the first negative pressure chamber 510, when the first negative pressure machine 520 is working, the first negative pressure chamber 510 can be in a negative pressure state, so that the dust overflowing from the main feeding port 210 is sucked into the first negative pressure chamber 510 through the first dust removal pipe 411, and the dust overflowing from the packaging device 300 is sucked into the first negative pressure chamber 510 through the second dust removal pipe 412. At the same time, the third electric gate valve 516 is controlled to be closed to avoid the powder storage container 4 20, the dust in the first negative pressure chamber 510 is sucked into the first negative pressure chamber 510; when the first negative pressure machine 520 is not working, the first negative pressure chamber 510 is not in a negative pressure state. At this time, the third electric gate valve 516 is controlled to open, and the dust recovered in the first negative pressure chamber 510 will be discharged into the powder storage container 420 through the first discharge port 514 under the action of gravity; in addition, since the second filter screen 515 is provided at the third opening 513, and the aperture of the second filter screen 515 is relatively small, under the action of the second filter screen 515, the dust in the first negative pressure chamber 510 can be prevented from entering the first negative pressure machine 520, thereby effectively reducing the loss of recovered dust.
[0061] In addition, refer to Figure 7 The first opening 511 and the second opening 512 are both arranged at the top of the first negative pressure chamber 510 , and the third opening 513 is arranged on the side wall of the first negative pressure chamber 510 .
[0062] It can be understood that when the dust in the first negative pressure chamber 510 is discharged into the powder storage container 420, since the first opening 511 is limited to be located at the top of the first negative pressure chamber 510, the dust in the first negative pressure chamber 510 can be prevented from re-entering the first dust removal duct 411 through the first opening 511, and since the second opening 512 is limited to be located at the top of the first negative pressure chamber 510, the dust in the first negative pressure chamber 510 can be prevented from re-entering the second dust removal duct 412 through the second opening 512; in addition, since the third opening 513 is limited to be set on the side wall of the first negative pressure chamber 510, it can further ensure that the dust sucked into the first negative pressure chamber 510 will not re-enter the first dust removal duct 411 or the second dust removal duct 412.
[0063] In addition, refer to Figure 2 and Figure 8 The lifting device 700 includes a conveying pipe 710, a second negative pressure chamber 720 and a second negative pressure machine 730. One end of the conveying pipe 710 is connected to the powder storage container 420. The second negative pressure chamber 720 is provided with a fourth opening 721, a fifth opening 722 and a second discharge port 723. The other end of the conveying pipe 710 is connected to the fourth opening 721. The second discharge port 723 is located at the bottom of the second negative pressure chamber 720. The second discharge port 723 is connected to the auxiliary feed port 220. The second negative pressure chamber 720 is located above the stirring device 200.

[0064] It can be understood that the lifting device 700 includes a conveying pipe 710, a second negative pressure chamber 720 and a second negative pressure machine 730. Since the air inlet of the second negative pressure machine 730 is connected to the fifth opening 722 of the second negative pressure chamber 720, when the second negative pressure machine 730 is working, the second negative pressure chamber 720 can be in a negative pressure state, so that the dust in the powder storage container 420 can be sucked into the second negative pressure chamber 720 through the conveying pipe 710 and the fourth opening 721 in sequence. At the same time, the fourth electric gate valve 221 is controlled to be closed to prevent the dust in the stirring device 200 from being sucked into the first negative pressure chamber 720 through the auxiliary feeding port 220. The second negative pressure chamber 720; when the second negative pressure machine 730 is not working, the second negative pressure chamber 720 is not in a negative pressure state. At this time, the fourth electric gate valve 221 is controlled to open, and the dust in the second negative pressure chamber 720 will be discharged into the stirring device 200 through the second discharge port 723 and the auxiliary feed port 220 in sequence under the action of gravity; in addition, since the third filter screen 740 is provided at the fifth opening 722, and the aperture of the third filter screen 740 is relatively small, under the action of the third filter screen 740, the dust in the second negative pressure chamber 720 can be prevented from entering the second negative pressure machine 730, thereby effectively reducing the loss of recovered dust.
[0065] In addition, refer to Fig. 9 The packaging device 300 includes a packaging machine body 310 and a filling tap 320 arranged on the packaging machine body 310 , and one end of the second dust removal pipe 412 faces the filling tap 320 .
[0066] It can be understood that by providing a filling faucet 320 for discharging dry mortar on the baler body 310, effective packaging of the dry mortar is facilitated, and one end of the second dust removal pipe 412 is limited to face the filling faucet 320, which can improve the recovery effect of overflow dust at the packaging device 300.
[0067] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
