Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, and in particular to a desulfurization ash conveying equipment. Background Technology

[0002] Desulfurization ash is a solid waste generated during the desulfurization process of industrial flue gas. It mainly comes from dry desulfurization processes, such as spray drying absorption towers. Its main component is calcium sulfite, and it also contains calcium carbonate, calcium hydroxide, a small amount of calcium chloride, calcium fluoride, and some fly ash.

[0003] The utility model patent with authorization announcement number CN202988276U provides a desulfurization ash conveying device, including a main ash hopper set under a secondary dust collector, multiple ash hoppers on the main ash hopper, a switch valve and a first expansion joint connected to each ash hopper and the main ash hopper, an air supply pipe connected to the main ash hopper, and an inclined trough on the main ash hopper; a first conveying ash channel connected to the inclined trough, an intermediate pipe connected to the first conveying ash channel, a throttling valve connected to the intermediate pipe, a first exhaust port at the top of the intermediate pipe, the intermediate pipe connected to a feeder, a second conveying ash channel connected to the throttling valve, the second conveying ash channel connected to a third conveying ash channel via a diverter, the other end of the third conveying ash channel connected sequentially to a second expansion joint and a pipe, and a second exhaust port at the top of the pipe.

[0004] The aforementioned patents utilize pipelines to transport desulfurization ash. However, since the desulfurization powder contains a large amount of mixed substances and is prone to absorbing water and clumping, pipeline transportation can easily cause blockages. To address the technical drawbacks of the aforementioned patents, we propose a desulfurization ash conveying device. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a desulfurization ash conveying device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A desulfurization ash conveying device includes a powder pump for conveying sulfur ash, a suction pipe provided on the side of the powder pump, and an anti-clogging component provided at the port of the suction pipe; the anti-clogging component includes a sleeve, a filter screen plate provided on the inner side of the sleeve, a fixed sleeve fixedly installed on the outer wall of the sleeve, a motor fixedly sleeved on the inner side of the fixed sleeve, a first rotating shaft fixedly installed on the output end of the motor, a bevel gear set provided at the end of the first rotating shaft, a second rotating shaft provided on the side of the bevel gear set, the first rotating shaft and the second rotating shaft being fixedly connected to the bevel gears in the bevel gear set respectively, an installation disc fixedly installed at the end of the second rotating shaft, and a plurality of crushing steel plates fixedly installed on the side of the installation disc.

[0008] Furthermore, a limiting stud is screwed onto the side wall of the sleeve, the limiting stud is screwed through to the inside of the sleeve, and the inner end of the limiting stud abuts against the outer wall of the suction pipe.

[0009] Furthermore, a hexagonal screw base is fixedly installed on the outer end of the limiting stud.

[0010] Furthermore, an abutment ring is fixedly installed on the inner wall of the sleeve, and the filter screen plate is located between the suction pipe and the abutment ring.

[0011] Furthermore, an expanding mask is fixedly installed at the sleeve port, a bent tube is provided on the inner side of the expanding mask, and a connecting rod is fixedly connected between the side wall of the bent tube and the inner wall of the expanding mask, and the first rotating shaft rotates through the expanding mask.

[0012] Furthermore, both the first and second rotating shafts are rotatably mounted inside the bend, and a sealing ring is provided between the second rotating shaft and the inner side of the bend port.

[0013] Furthermore, the crushing steel sheets are arranged in an alternating pattern on the side wall of the mounting disc.

[0014] Furthermore, a first snap-fit ​​ring and a second snap-fit ​​ring are fixedly installed on the upper side of the powder pump, the suction pipe is fixedly snapped to the first snap-fit ​​ring, and a conveying pipe is snapped and fixed to the side of the second snap-fit ​​ring.

[0015] Compared with related technologies, the desulfurization ash conveying equipment proposed in this utility model has the following beneficial effects:

[0016] In this utility model, a desulfurization ash conveying device is provided. An anti-clogging component is installed, in which a motor drives a first rotating shaft to rotate, and a bevel gear set drives a second rotating shaft to rotate. The second rotating shaft causes a mounting disc to rotate inside a sleeve, simultaneously causing crushing steel plates to rotate on the side of a filter screen plate installed inside the sleeve. This crushes the desulfurization ash and draws it through the filter screen plate into the suction pipe, preventing clumped desulfurization ash from being directly sucked into the pipe and avoiding blockage. This allows for smooth conveying of the desulfurization ash through a pumping system, ensuring the conveying rate of the desulfurization ash and enhancing its practicality.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Reference Figure 1-6 A desulfurization ash conveying device includes a powder pump 1 for conveying sulfur ash, a suction pipe 5 on the side of the powder pump 1, and an anti-clogging component 6 at the port of the suction pipe 5. The anti-clogging component 6 includes a sleeve 61, a filter screen plate 65 on the inner side of the sleeve 61, a fixed sleeve 66 fixedly installed on the outer wall of the sleeve 61, a motor 67 fixedly sleeved on the inner side of the fixed sleeve 66, a first rotating shaft 611 fixedly installed on the output end of the motor 67, a bevel gear set 612 on the end of the first rotating shaft 611, a second rotating shaft 613 on the side of the bevel gear set 612, the first rotating shaft 611 and the second rotating shaft 613 being fixedly connected to the bevel gears in the bevel gear set 612, and an installation disc 614 fixedly installed on the end of the second rotating shaft 613, with a plurality of crushing steel plates 615 fixedly installed on the side of the installation disc 614.

[0026] In this method, an expanding mask 62 is fixedly installed at the end of the sleeve 61, and a bent tube 68 is provided on the inner side of the expanding mask 62. A connecting rod 610 is fixedly connected between the side wall of the bent tube 68 and the inner wall of the expanding mask 62, and the first rotating shaft 611 rotates through the expanding mask 62.

[0027] By setting up the above-mentioned bend 68, the first rotating shaft 611, the second rotating shaft 613 and the bevel gear set 612 are protected inside the bend 68. When the first rotating shaft 611 and the second rotating shaft 613 mesh and transmit power, they are protected by the outer bend 68, so that their meshing space is kept sealed and the desulfurization ash is prevented from interfering with the meshing of the bevel gear set 612.

[0028] In this configuration, both the first rotating shaft 611 and the second rotating shaft 613 are rotatably mounted inside the bend 68, and a sealing ring 616 is provided between the second rotating shaft 613 and the inner side of the bend 68 port.

[0029] By setting the sealing ring 616 in the above manner, desulfurization ash is prevented from entering the inside of the bend 68 through the port of the bend 68.

[0030] In this method, the crushing steel sheets 615 are staggered on the side wall of the mounting disc 614.

[0031] With the above arrangement, the crushing steel sheets 615 are staggered on the side wall of the mounting disc 614, making it easier to crush the desulfurization ash when the mounting disc 614 drives the crushing steel sheets 615 to rotate.

[0032] In this method, a first snap-fit ​​ring 2 and a second snap-fit ​​ring 3 are fixedly installed on the upper side of the powder pump 1, the suction pipe 5 is fixedly snapped to the first snap-fit ​​ring 2, and the conveying pipe 4 is snapped and fixed to the side of the second snap-fit ​​ring 3.

[0033] In this method, a limiting stud 63 is screwed onto the side wall of the sleeve 61. The limiting stud 63 is screwed through to the inside of the sleeve 61. The inner end of the limiting stud 63 abuts against the outer wall of the suction pipe 5. A hexagonal screw seat 64 is fixedly installed on the outer end of the limiting stud 63.

[0034] With the above-mentioned configuration, the hexagonal screw seat 64 can drive the limiting stud 63 to rotate, thereby causing the inner end of the limiting stud 63 to abut against the outer wall of the suction pipe 5, and thus the sleeve 61 is fixedly sleeved on the outer wall of the suction pipe 5.

[0035] In this method, an abutment ring 69 is fixedly installed on the inner wall of the sleeve 61, and the filter screen plate 65 is located between the suction pipe 5 and the abutment ring 69.

[0036] With the above-described configuration, the filter screen plate 65 is pressed between the suction pipe 5 port and the abutment ring 69. When the sleeve 61 is removed from the suction pipe 5 port, the filter screen plate 65 can be removed from the inside of the sleeve 61, making the replacement of the filter screen plate 65 more convenient.

[0037] The working principle of the desulfurization ash conveying equipment provided by this utility model is as follows:

[0038] In use, the powder pump 1 is turned on, and the motor 67 is turned on at the same time. Under the action of the powder pump 1, a suction force is generated at the port of the suction pipe 5, which in turn generates a suction force at the expansion mask 62 at the outer end of the sleeve 61, sucking the desulfurization ash into the inner side of the sleeve 61. At the same time, the motor 67 drives the first rotating shaft 611 to rotate, and the bevel gear set 612 drives the second rotating shaft 613 to rotate, so that the second rotating shaft 613 drives the mounting disc 614 and the crushing steel plate 615 to rotate on the side of the filter screen plate 65 inside the sleeve 61, crushing the desulfurization ash and sucking it into the suction pipe 5 through the filter screen plate 65. The desulfurization ash entering the suction pipe 5 enters the working chamber of the powder pump 1, and is subsequently transported through the conveying pipe 4.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
