Description

Technical Field

[0001] This utility model belongs to the technical field of quartz sand production equipment, specifically, it relates to an ash unloading device and a pulse bag dust collector for quartz sand production. Background Technology

[0002] In the production of quartz sand, pulse jet bag filters are frequently used for dust removal. Currently, to facilitate the cleaning of filtered dust in the bottom hopper of the pulse jet bag filter, quartz sand production companies often install a dust discharge trolley at the bottom of the hopper. The trolley is tightly fitted to the bottom of the hopper via a clamping structure. When the amount of dust in the trolley is large or after a certain period of time, the trolley needs to be removed from the hopper to empty the dust. After emptying, the trolley is then reinstalled at the bottom of the pulse jet bag filter. Because the production of quartz sand requires multi-stage crushing and screening of raw materials, a large amount of dust is generated, especially in the production of high-purity quartz sand. Workers need to clean the ash unloading trolley frequently. Currently, each cleaning of the ash unloading trolley takes a long time, and during cleaning, the bottom of the ash hopper of the pulse bag filter often needs to be closed by a valve, which affects the normal dust removal of the pulse bag filter. At present, it is often difficult to judge the amount of dust in the ash unloading trolley during the use of the pulse bag filter. Often, it is emptied at regular intervals, which makes the cleaning timing of the ash unloading trolley inaccurate. Occasionally, there will be too much or too little dust in the ash unloading trolley during cleaning. Summary of the Invention

[0003] The purpose of this utility model is to provide an ash unloading device and a pulse bag filter for quartz sand production, so as to overcome the problems existing in the pulse bag filter for quartz sand production, such as long cleaning time of the ash unloading trolley, the impact of the ash unloading trolley on the normal operation of the pulse bag filter during cleaning, and the inability to judge the amount of dust in the ash unloading trolley.

[0004] This utility model is achieved by the following technical solution: an ash unloading device, including front and rear side slide rails, a sliding plate slidably mounted on the side slide rails, the sliding plate being connected to a first driving device that can drive it to move along the side slide rails, sliders cooperating with the side slide rails being installed on the front and rear sides of the bottom of the sliding plate, ash unloading buckets being installed on the left and right sides of the top surface of the sliding plate, an electronic scale being installed at the bottom of the ash unloading bucket, and a second driving device that can drive the ash unloading bucket to move up and down being installed on the lower side of each ash unloading bucket.

[0005] Furthermore, the top surface of the ash discharge bucket is equipped with an annular protrusion, and the top surface of the protrusion has an annular groove, in which a rubber sealing ring is installed.

[0006] Furthermore, the first driving device includes a first telescopic cylinder disposed on one side of the sliding plate, the piston rod of the first telescopic cylinder being connected to the sliding plate; the first telescopic cylinder is a pneumatic cylinder.

[0007] Furthermore, the second driving device includes a guiding assembly and a lifting assembly. The guiding assembly includes multiple guide cylinders and multiple guide rods corresponding to each guide cylinder. The guide cylinders are fixedly installed on the top surface of the sliding plate, and the guide rods are fixedly installed on the bottom surface of the ash discharge bucket and inserted into the corresponding guide cylinders. The lifting assembly includes a telescopic plate, which is connected to a second telescopic cylinder. The second telescopic cylinder can drive the telescopic plate to move horizontally. At least one lifting block is installed on the top surface of the telescopic plate. The lifting block has a lifting surface on one side along the moving direction of the telescopic plate. The lifting surface includes an inclined surface. A support shaft is installed on the bottom of the ash discharge bucket on the upper side of each lifting block. At least one lifting wheel is installed on the support shaft, and the lifting wheel abuts against the lifting surface.

[0008] Furthermore, two lifting blocks are installed on the top surface of the telescopic plate, and the two lifting blocks are arranged at intervals along the moving direction of the telescopic plate.

[0009] Furthermore, the lifting surface also includes an upper horizontal surface and a lower horizontal surface on both sides, and the upper and lower ends of the inclined surface are respectively connected to the upper horizontal surface and the lower horizontal surface.

[0010] Furthermore, two lifting wheels are installed on the support shaft, which is rotatably mounted at the bottom of the ash discharge bucket.

[0011] Furthermore, the second telescopic cylinder is a pneumatic cylinder.

[0012] Furthermore, the sliding plate is equipped with guide plates on both sides of the telescopic plate, and the bottom of the two guide plates is provided with opposite guide grooves, and the two sides of the telescopic plate are respectively inserted into the two guide grooves.

[0013] A pulse bag filter dust collector for quartz sand production includes a dust hopper and the aforementioned dust discharge device. The slide rails on the front and rear sides are arranged below the dust outlet of the dust hopper. One of the dust discharge buckets on both sides is always opposite the dust outlet of the dust hopper. A bag is installed in the dust discharge bucket. The dust outlet of the dust hopper is provided with a dust hopper flange.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Compared with the existing ash unloading trolley, this utility model can significantly shorten the ash cleaning time. In application, a bag is installed in the ash unloading bucket opposite the ash outlet of the ash hopper of the pulse bag filter. The bag opening extends outward from the outer convex edge of the ash unloading bucket. During the process of the outer convex edge tightly fitting with the ash outlet of the ash hopper, the bag will be tightly clamped between the outer convex edge and the ash outlet of the ash hopper. In this way, when the dust in the ash hopper falls into the ash unloading bucket, it will fall directly into the bag in the ash unloading bucket. When it is necessary to clean the dust in the ash unloading bucket, simply take the bag containing the dust out of the ash unloading bucket and tie the bag opening. It is very convenient and quick, and also avoids the problem of secondary dust pollution during cleaning.

[0016] 2. When cleaning the dust in one side of the ash discharge bucket, the other side of the ash discharge bucket will be aligned with the ash outlet of the ash hopper at the same time. The second telescopic cylinder will make the outer protruding edge of the top of the ash discharge bucket on this side fit tightly with the ash outlet of the ash hopper, thereby greatly reducing the impact of the ash discharge bucket on the normal operation of the pulse bag dust collector during the dust cleaning process.

[0017] 3. This utility model allows for the weighing of bags inside the ash discharge bin by installing an electronic scale inside the bin, thus accurately determining the amount of dust within the bin. In application, a bag is installed in the ash discharge bin opposite the ash outlet of the pulse bag filter dust collector. The length of the portion of the bag inside this side of the ash discharge bin is greater than the height of the bin. When dust falls into the bag, the bottom of the bag contacts the electronic scale at the bottom of this side of the ash discharge bin. The electronic scale weighs the dust inside the bag and transmits this weight to the controller. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort should fall within the scope of protection of this utility model.

[0026] A dust removal device includes front and rear slide rails 1, with a sliding plate 2 slidably mounted on the slide rails 1. Sliding blocks 3 that cooperate with the slide rails 1 are respectively installed on the front and rear sides of the bottom of the sliding plate 2. Multiple sliding blocks 3 are installed at intervals on the front and rear sides of the bottom of the sliding plate 2. The sliding plate 2 moves along the slide rails 1 via the sliding blocks 3 at the bottom.

[0027] The sliding plate 2 is connected to a first driving device that can drive it to move along the two side slide rails 1. The first driving device includes a first telescopic cylinder 8 disposed on one side of the sliding plate 2, and the piston rod of the first telescopic cylinder 8 is connected to the sliding plate 2. Figure 1 As shown, the first telescopic cylinder 8 can be located on the right side of the sliding plate 2. When the piston rod of the first telescopic cylinder 8 extends, it can drive the sliding plate 2 to move to the left along the two side slide rails 1. When the piston rod of the first telescopic cylinder 8 retracts, it can drive the sliding plate 2 to move to the right along the two side slide rails 1. The first telescopic cylinder 8 is a pneumatic cylinder.

[0028] Ash discharge buckets 4 are respectively installed on the left and right sides of the top surface of the sliding plate 2. The top surface of each ash discharge bucket 4 has an annular outer protrusion 6, and an annular groove is formed on the top surface of the outer protrusion 6. A rubber sealing ring 7 is installed inside the annular groove. The ash discharge bucket 4 of this invention is cylindrical. By setting the outer protrusion 6, this invention allows the ash discharge bucket 4 to better fit tightly with the ash discharge port flange 24 of the pulse bag filter dust collector. To further enhance the tight fit between the outer protrusion 6 and the bottom ash discharge port flange 24 of the ash hopper 22, an annular groove is formed on the top surface of the outer protrusion 6, and a rubber sealing ring 7 is installed inside the annular groove. An annular sealing groove opposite to the annular groove can also be formed on the ash discharge port flange 24.

[0029] An electronic scale 5 is installed at the bottom of the ash discharge bin 4. The electronic scale 5 is connected to a controller and can detect the weight of the bag 23 inside the ash discharge bin 4. In application, the ash discharge bin 4, which is opposite the ash outlet of the ash hopper 22 of the pulse bag filter, has a bag 23 installed inside it. The length of the portion of the bag 23 inside this side of the ash discharge bin 4 is greater than the height of the ash discharge bin 4. So when dust falls into the bag 23, the bottom of the bag 23 will contact the electronic scale 5 at the bottom of this side of the ash discharge bin 4, allowing the electronic scale 5 to weigh the dust inside the bag 23. At the same time, the electronic scale 5 will transmit the weight of the dust inside the bag 23 to the controller.

[0030] Each sliding plate 2 is equipped with a second driving device on the underside of each ash discharge bin 4, which can drive the ash discharge bin 4 to move up and down. The second driving device includes a guide assembly and a lifting assembly. The guide assembly includes multiple guide cylinders 9 and multiple guide rods 10 corresponding to each guide cylinder 9. The guide cylinders 9 are fixedly installed on the top surface of the sliding plate 2, and the guide rods 10 are fixedly installed on the bottom surface of the ash discharge bin 4 and are inserted into the corresponding guide cylinders 9.

[0031] The guide assembly described in this utility model can only move the ash discharge bucket 4 up and down. When the ash discharge bucket 4 moves up and down, the guide rod 10 will move up and down along the guide cylinder 9.

[0032] The lifting assembly includes a telescopic plate 11, which is connected to a second telescopic cylinder 12. The second telescopic cylinder 12 is a pneumatic cylinder that can drive the telescopic plate 11 to move horizontally. Two lifting blocks 13 are installed on the top surface of the telescopic plate 11. The two lifting blocks 13 are arranged at intervals along the moving direction of the telescopic plate 11. One side of the lifting block 13 along the moving direction of the telescopic plate 11 is provided with a lifting surface 14. The lifting surface 14 includes an inclined surface 15. The lifting surface 14 also includes an upper horizontal surface 18 and a lower horizontal surface 19 on the upper and lower sides. The upper and lower ends of the inclined surface 15 are respectively connected to the upper horizontal surface 18 and the lower horizontal surface 19. The lower horizontal surface 19, the inclined surface 15, and the upper horizontal surface 18 form a Z-shape. The upper horizontal surface 18 and the inclined surface 15, and the lower horizontal surface 19 and the inclined surface 15 are all connected by arcs.

[0033] The bottom of the ash discharge bin 4 is equipped with a support shaft 16 on the upper side of each lifting block 13. Two lifting wheels 17 are mounted on each support shaft 16, and the support shaft 16 is rotatably mounted on the bottom of the ash discharge bin 4. In this invention, when two lifting blocks 13 are installed on the top surface of the telescopic plate 11, two support shafts 16 are correspondingly rotatably mounted on the bottom of the ash discharge bin 4. The support shafts 16 are rotatably mounted on the bottom of the ash discharge bin 4 via a mounting plate 25. The mounting plate 25 is fixedly connected to the bottom of the ash discharge bin 4, and bearing seats are installed on both sides of the bottom of the mounting plate 25. The two ends of the support shafts 16 are rotatably mounted in the bearing seats on both sides of the bottom of the mounting plate 25.

[0034] The sliding plate 2 has guide plates 20 installed on both sides of the telescopic plate 11. The bottom of each guide plate 20 has a corresponding guide groove 21. Both sides of the telescopic plate 11 are inserted into the guide grooves 21. This invention, by installing the guide plates 20 and creating the guide grooves 21, and by inserting both sides of the telescopic plate 11 into the guide grooves 21, makes the movement of the telescopic plate 11 more stable.

[0035] In the lifting process of the ash discharge bucket 4 described in this utility model, when the second telescopic cylinder 12 drives the telescopic plate 11 to move away from the second telescopic cylinder 12, the lifting block 13 on the telescopic plate 11 also moves away from the second telescopic cylinder 12 at the same time. Since the ash discharge bucket 4 can only move up and down, the lifting wheel 17 on the ash discharge bucket 4 will move upward relative to the inclined surface 15 of the lifting block 13, causing the lifting wheel 17 to move upward, and thus causing the ash discharge bucket 4 to move upward. When the lifting wheel 17 moves to the upper horizontal surface 18, the lifting wheel 17 and the ash discharge bucket 4 move upward to the highest point, at which time the outer protruding edge 6 of the ash discharge bucket 4 will be tightly fitted with the ash hopper flange 24. Similarly, when the second telescopic cylinder 12 drives the telescopic plate 11 to move closer to the second telescopic cylinder 12, the lifting wheel 17 will move downward along the inclined surface 15 of the lifting surface 14, causing the ash discharge bucket 4 to move downward as well. When the lifting wheel 17 moves to the lower horizontal surface 19, the lifting wheel 17 and the ash discharge bucket 4 move downward to the lowest point.

[0036] A pulse bag filter dust collector for quartz sand production includes a dust hopper 22 and the aforementioned dust discharge device. The dust discharge device is located below the dust outlet of the dust hopper 22. One of the two dust discharge buckets 4 is always opposite the dust outlet of the dust hopper 22. A bag 23 is installed in the dust discharge bucket 4. The dust outlet of the dust hopper 22 is provided with a dust hopper flange 24.

[0037] This invention uses a second driving device to drive the outer protruding edge 6 on the ash discharge bucket 4 below the ash outlet of the ash hopper 22 to make close contact with the ash hopper flange 24. In application, bags 23 are placed in both ash discharge buckets 4. The length of the bags 23 is much greater than the height of the ash discharge buckets 4. When placing the bags 23 into the ash discharge buckets 4, the openings of the bags 23 should extend completely beyond the outer protruding edge 6. This ensures that the bags 23 are sandwiched between the outer protruding edge 6 and the ash hopper flange 24 during the close contact process, thus guaranteeing that all the dust flowing out of the ash discharge outlet of the ash hopper 22 enters the bags 23. Simultaneously, the length of the bags 23 inside the ash discharge buckets 4 is also greater than the height of the ash discharge buckets 4. This ensures that when dust enters the bags 23, the bottom of the bags 23 will contact the electronic scale 5 under the influence of the dust's gravity, and the electronic scale 5 can weigh the dust in the bags 23.

[0038] The working process of this utility model is as follows: First, place two bags 23 into two ash discharge bins 4 respectively, and make the mouths of the bags 23 extend out of the outer convex edge 6 of the ash discharge bin 4. At the same time, the length of the bags 23 inside the ash discharge bin 4 is greater than the height of the ash discharge bin 4.

[0039] Then, align the left ash discharge bucket 4 with the ash outlet of the ash hopper 22, and start the second telescopic cylinder 12 on the lower side of the left ash discharge bucket 4. The second telescopic cylinder 12 drives the left ash discharge bucket 4 to move upward a certain distance, so that the outer protrusion 6 of the left ash discharge bucket 4 is tightly fitted with the ash hopper flange 24, and at the same time, the bag 23 is also sandwiched between the outer protrusion 6 and the ash hopper flange 24.

[0040] The dust in the ash hopper 22 enters the bag 23 inside the ash discharge bucket 4 from the ash outlet. The electronic scale 5 weighs the dust in the bag 23 and transmits the weight signal to the controller. When the weight of the dust in the bag 23 reaches the set value, the controller first controls the second telescopic cylinder 12 on the lower side of the left ash discharge bucket 4 to work, so that the left ash discharge bucket 4 descends and does not fit with the ash hopper flange 24. Then, it controls the first telescopic cylinder 8 to work, so that the left ash discharge bucket 4 moves to the left and away from the ash outlet of the ash hopper 22. At the same time, it moves the right ash discharge bucket 4 to the left and moves to the lower side of the ash outlet of the ash hopper 22. Finally, it works the second telescopic cylinder 12 under the ash discharge bucket 4 on the lower side of the ash outlet of the right ash hopper 22, so that the outer protrusion 6 of the right ash discharge bucket 4 fits tightly with the ash hopper flange 24. Finally, the bag 23 containing dust in the left ash discharge bucket 4 is taken out of the left ash discharge bucket 4 and the bag 23 opening is tied.
