Description

Technical Field

[0001] This utility model relates to the technical field of sludge conveying equipment, specifically to a vibrating feeder for sludge conveying. Background Technology

[0002] A vibrating feeder is a general-purpose device that uses the principle of vibration for feeding. It is mainly used in the feeding, batching, and automatic control systems of mining, mineral processing, metallurgy, coal mining and other industrial and mining enterprises.

[0003] Currently, belt conveyors and screw conveyors are commonly used in the application of semi-dry sludge conveying equipment.

[0004] The problem with existing technologies is that, to prevent sludge from clumping and clogging the system, it needs to be broken up. However, traditional mechanical extrusion conveying causes water to be squeezed out of the sludge, leading to equipment overflow and an unpleasant working environment. Vibration conveying avoids water squeezing out by spreading the sludge thinly. However, since the sludge is continuously fed into the vibrating feeder, the thickness of the spread layer depends on the area of ​​the conveyor belt. Because the area is fixed, as the amount of sludge input increases, the sludge thickness increases. The buffering effect of the thick sludge layer leads to a decrease in the effectiveness of dispersing surface clumps.

[0005] Therefore, it is necessary to improve the transmission structure of the vibrating feeder to prevent the formation of thick sludge layers and improve the dispersing effect. Utility Model Content

[0006] To address the shortcomings of the aforementioned technologies, this invention provides a vibrating feeder for sludge conveying.

[0007] The technical solution of this utility model is as follows: A vibrating feeder for sludge conveying includes a housing and an eccentric vibrating motor. A feeding channel is provided inside the housing. The feeding channel is inclined and has an inlet at its high point and an outlet at its low point. It also includes a plurality of scale-like vibrating blocks arranged along the feeding channel. Each scale-like vibrating block includes a connecting part and a guide top surface. The guide top surface includes an inlet side, an outlet side, and a apex. The apex is respectively provided with a first slope and a second slope in the shape of an "eight" between it and the inlet side and the outlet side. A cantilever part is provided on the outlet side. The plurality of scale-like vibrating blocks are connected end to end to form a feeding chain. The cantilever part near the inlet side is supported on the adjacent second slope near the outlet side.

[0008] The connecting part of the scale-like vibrating block is provided with a hinge hole and an eccentric arc-shaped guide groove. The eccentric arc-shaped guide groove includes an upper limit end and a lower limit end. The housing is provided with a number of limiting shafts extending into each eccentric arc-shaped guide groove and a rotating shaft hinged to the hinge hole. The scale-like vibrating block reciprocates along the eccentric arc-shaped guide groove as it vibrates. When the upper limit end of the eccentric arc-shaped guide groove abuts against the limiting shaft, the cantilever part is placed on the adjacent second slope. When the lower limit end of the eccentric arc-shaped guide groove abuts against the limiting shaft, the cantilever part is raised away from the second slope.

[0009] A further feature of this invention is that a feeding ramp is provided vertically below the feeding chain in the feeding channel, with the side of the feeding ramp near the inlet being higher than the other side.

[0010] A further feature of this invention is that the machine casing is provided with several sets of eccentric vibration motors along the feeding chain, and the vibration frequencies of these sets of eccentric vibration motors increase or decrease or vary in order of proximity to the discharge port.

[0011] A further feature of this invention is that a steam channel is provided vertically above the feeding channel, the steam channel being equipped with an inlet pipe and an outlet pipe, and connected to the high-temperature steam in the factory area.

[0012] The beneficial effects of this utility model are as follows: as shown in the appendix to the specification. Figure 2 , 3 As shown, semi-dry sludge falls onto the feeding chain from the inlet. The scale-like vibrating block swings back and forth along the eccentric arc-shaped guide groove as it vibrates. When the upper limit end of the eccentric arc-shaped guide groove abuts against the limit shaft, the cantilever is placed on the adjacent second slope. At this time, the feeding chain is connected end to end, forming a whole slope. The sludge slides along the feeding chain towards the outlet.

[0013] Under vibration, when the lower limit end of the eccentric arc-shaped guide groove abuts against the limit shaft, the cantilever part lifts up and leaves the second slope. With the rotation angle, the first slope rotates to a horizontal angle or a negative angle. Part of the sludge flows to the next vibrating block, and part remains on the vibrating block, forming the effect of breaking up the sludge. At this time, small clumps of sludge are diverted on each vibrating block. The area is the same but the total amount decreases, and the sludge can be dispersed into thinner pieces. The scale-like vibrating blocks of the feeding chain undulate back and forth, continuously breaking the sludge into small clumps, thereby achieving the purpose of improving the vibration effect.

[0014] Then, by inputting high-temperature steam from the plant area, the temperature inside the casing is increased, which accelerates the drying of sludge and assists in subsequent dewatering. Attached Figure Description

[0022] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-4 As shown,

[0023] A vibrating feeder for sludge conveying includes a housing 1 and an eccentric vibrating motor 2. The housing 1 is provided with a feeding channel 11, which is inclined. The feeding channel 11 has a feed inlet 13 at its high point and a discharge outlet 14 at its low point. It also includes a plurality of scale-like vibrating blocks 4 arranged along the feeding channel 11. Each scale-like vibrating block includes a connecting part 41 and a guide top surface. The guide top surface includes a feed side, a discharge side, and a vertex 42. The vertex 42 is provided with a first slope 43 and a second slope 44 in the shape of an "eight" between it and the feed side and the discharge side, respectively. The discharge side is provided with a cantilever part 45. The plurality of scale-like vibrating blocks 4 are connected end to end to form a feeding chain 3. The cantilever part 45 on the side near the feed inlet 13 is supported on the adjacent second slope 44 on the side near the discharge outlet 14.

[0024] The connecting part 41 of the scale-like vibrating block is provided with a hinge hole 47 and an eccentric arc-shaped guide groove 46. The eccentric arc-shaped guide groove 46 includes an upper limit end 461 and a lower limit end 462. The housing 1 is provided with a plurality of limit shafts 463 extending into each eccentric arc-shaped guide groove 46 and a rotating shaft 464 connected to the hinge hole. The scale-like vibrating block oscillates back and forth along the eccentric arc-shaped guide groove 46 with vibration. When the upper limit end 461 of the eccentric arc-shaped guide groove 46 abuts against the limit shaft 463, the cantilever part 45 is placed on the adjacent second slope 44. When the lower limit end 462 of the eccentric arc-shaped guide groove 46 abuts against the limit shaft 463, the cantilever part 45 is raised away from the second slope 44.

[0025] The feeding channel 11 is provided with a feeding ramp 12 vertically below the feeding chain 3, and the side of the feeding ramp 12 closest to the feed inlet 13 is higher than the other side.

[0026] The housing 1 is provided with several sets of eccentric vibration motors 2 along the feeding chain 3. The vibration frequency of these sets of eccentric vibration motors 2 increases or decreases or varies in order of proximity to the discharge port 14.

[0027] A steam channel 15 is provided vertically above the feeding channel 11. The steam channel 15 is equipped with an air inlet pipe and an air outlet pipe, and is connected to the high-temperature steam in the plant area.

[0028] As per the instruction manual Figure 2 , 3 As shown, semi-dry sludge falls from the feed inlet 13 onto the feeding chain 3. The scale-like vibrating block swings back and forth along the eccentric arc-shaped guide groove 46 as it vibrates. When the upper limit end 461 of the eccentric arc-shaped guide groove 46 abuts against the limit shaft 463, the cantilever part 45 is placed on the adjacent second slope 44. At this time, the feeding chain 3 is connected end to end, forming a whole slope. The sludge slides along the feeding chain 3 towards the discharge port 14.

[0029] Under vibration, when the lower limit end 462 of the eccentric arc-shaped guide groove 46 abuts against the limit shaft 463, the cantilever part 45 tilts up away from the second slope 44. With the rotation angle, the first slope 43 rotates to a horizontal angle or a negative angle. Part of the sludge flows to the next vibrating block, and part remains on the vibrating block, forming the effect of breaking the sludge. At this time, small clumps of sludge are diverted on each vibrating block. The area is the same but the total amount decreases, and the sludge can be dispersed into thinner pieces. The scale-like vibrating blocks of the feeding chain 3 undulate back and forth, continuously breaking the sludge into small clumps, thereby achieving the purpose of improving the vibration effect.

[0030] Then, by inputting high-temperature steam from the plant area, the temperature inside the casing 1 is increased, which accelerates the drying of sludge and assists in subsequent dewatering.
