Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor water removal, in particular to a sand and gravel conveying belt conveyor roller device for controlling the water content of sand and gravel. Background Art

[0002] At present, the production process of sand and gravel aggregates can be divided into dry sand making and wet sand making. The two process methods have their own advantages and disadvantages, but in both sand and gravel aggregate manufacturing processes, belt conveyors (belt conveyors) are required to transport and transfer materials (sand and gravel aggregates).

[0003] However, when the belt conveyor is used for wet sand making process, since the sand and gravel aggregates contain moisture, when the belt conveyor is working, part of the moisture is transported with the aggregates, and part of the moisture and fine aggregates stick to the belt and splash and fall everywhere during the return operation, thus causing a poor on-site environment around the belt conveyor, seriously affecting the factory appearance and increasing a lot of sanitation and cleaning work. Moreover, if the moisture is not cleaned in time, when the sand and gravel aggregates are continuously transported in the subsequent process, since there are water stains on the belt surface (the water stains will not splash all over during the return process), when the sand and gravel aggregates fall onto the belt conveyor, these moisture will first affect the moisture content of the subsequent sand and gravel aggregates. Secondly, some moisture will splash to the front and rear sides and flow out from various gaps on the belt conveyor, thus accelerating the wear of the conveyor rollers, resulting in the life of the belt conveyor used for wet sand making being generally only half of that of the dry sand making belt conveyor. For this reason, a sand and gravel conveyor belt conveyor roller device for controlling the moisture content of sand and gravel is proposed. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] In this embodiment, a sand and gravel conveyor belt conveyor roller device for controlling the water content of sand and gravel is used in conjunction with the belt conveyor in the prior art to remove water from the belt 1 of the return section of the belt conveyor, so that the belt 1 remains relatively dry each time it moves from the return section to the conveying section, thereby controlling the water content of sand and gravel, extending the service life of the belt conveyor and ensuring that the environment around the belt conveyor is relatively clean. Figure 1 and Figure 2 As shown, the sand and gravel conveyor belt conveyor roller device for controlling the moisture content of sand and gravel includes a dewatering structure 2 and a support structure 3, wherein the dewatering structure 2 includes an upper roller 21 and a lower water squeezing roller 22, and the lower water squeezing roller 22 and the support structure 3 include a bracket 31, a fixed sleeve 33, a movable sleeve 34 and a receiving hopper 35.

[0025] To facilitate understanding of the structure, position and function of the water removal structure 2 and the support structure 3, further explanation is provided here.

[0026] First, if Figure 1 and 2 As shown, the upper support roller 21 and the lower squeeze roller 22 in the water removal structure 2 are distributed up and down, and can be rotatably arranged on the upper and lower sides of the return section of the belt 1.

[0027] As for the two sets of brackets 31 in the above-mentioned support structure 3, they are distributed on the front and rear sides of the belt 1, and the fixing sleeves 33 are fixed on the outside of the brackets 31 by bolts. The upper roller 21 is rotatably connected to the brackets 31 through the fixing sleeves 33. Figure 2 and 3 As shown, at this time, the front and rear sides of the upper roller 21 are located on the inner side of the fixed sleeve 33, thereby meeting the rotatable requirement of the upper roller 21. A movable sleeve 34 is elastically supported on the outer side of the bracket 31, and the lower water-squeezing roller 22 is rotatably connected to the bracket 31 through the movable sleeve 34, so that the lower water-squeezing roller 22 elastically and constantly abuts against the lower side of the belt 1. A receiving hopper 35 for collecting mud water is provided below the lower water-squeezing roller 22.

[0028] To facilitate understanding of how the movable sleeve 34 is elastically supported on the outer side of the bracket 31, as shown in FIG. Figure 2 and 3 As shown, an elastic supporting component 32 is provided on the outer side of the bracket 31 , and the movable sleeve 34 is elastically supported on the outer side of the bracket 31 by the elastic supporting component 32 .

[0029] To further explain, the elastic support component 32 includes a bracket 321, a sleeve rod 322, a rotary dial 323 and a spring 1 324, wherein a movable hole is opened on the bracket 321, the sleeve rod 322 is movably connected to the inner side of the movable hole, and the top of the sleeve rod 322 is fixedly connected to the movable sleeve 34, the rotary dial 323 is located below the bracket 321, and is threadedly connected to the outer side of the sleeve rod 322, and the spring 1 324 is fixedly set on the outer side of the sleeve rod 322 and is located between the bracket 321 and the rotary dial 323.

[0030] In addition, as a preferred design of the receiving hopper 35, there is a support bar 36 between the receiving hopper 35 and the bracket 31, so that the receiving hopper 35 can provide support for the bracket 31. Of course, it can be understood that in another embodiment, the receiving hopper 35 and the bracket 31 can also be detachably arranged on the frame of the belt conveyor.

[0031] It should also be noted that if Figure 1As shown, a sewage pipe 4 is fixedly provided at the bottom of the receiving hopper 35 for draining the muddy water captured by the receiving hopper 35. The sewage pipe 4 is actually connected to the sewage pool in the factory, so that the muddy water can be discharged into the sewage pool. The sewage pool is a prior art and is not the focus of this application. It is not shown in the figure and will not be described in detail here. In addition, as a preferred solution for the lower squeezing roller 22, the lower squeezing roller 22 has a PVA water-absorbing sponge layer. In this way, the lower squeezing roller 22 is actually a PVA water-absorbing sponge roller in the prior art, which has water-absorbing properties. First, the lower squeezing roller 22 can complete the water absorption work of the belt 1, and when it rotates and reciprocates, it will bring out water to ensure that the belt 1 is relatively dry, and allow the receiving hopper 35 to complete the collection to ensure the cleanliness of the environment around the belt machine.

[0032] When designed in this way, when the belt 1 is working, each time the belt 1 moves from the conveying section to the return section, the receiving hopper 35 continuously receives water, and when the water on the surface of the belt 1 passes between the upper roller 21 and the lower squeezing roller 22, the lower squeezing roller 22 will absorb water, and under the influence of the spring 1 324, the lower squeezing roller 22 will squeeze the water, ensuring that the lower squeezing roller 22 continuously completes the dehydration treatment of the belt 1, and the water will fall into the receiving hopper 35 under the influence of gravity. In this way, the belt 1 is dehydrated and cleaned when the belt 1 returns in the belt conveyor, and the water stains are collected, thereby improving the on-site environment of the belt conveyor. In addition, such a design can reduce the moisture on the surface of the belt 1, thereby preventing the moisture on the belt 1 from mixing with the subsequent sand and gravel aggregates, thereby achieving the purpose of controlling the moisture content of the sand and gravel. In addition, since the belt 1 is kept relatively dry during the conveying section, it can reduce the splashing of water and reduce the current situation of water stains flowing out of the gaps in the belt conveyor, thereby extending the service life of the belt conveyor.

[0033] In one embodiment, in order to clean up the water flowing down from the front and rear sides of the belt 1 in time, the water on the front and rear sides of the belt 1 is removed, such as Figure 1-3 As shown, the water removal structure 2 also includes a number of side pressure rollers 23 distributed on the front and rear sides of the belt 1. The outer side of the side pressure rollers 23 is provided with an elastic supporting structure 5 connected to the bracket 31, so that the side pressure rollers 23 can elastically abut against the front and rear sides of the belt 1 and also clean and remove water from the front and rear sides of the belt 1.

[0034] To further explain, the elastic supporting structure 5 includes a mounting platform 51, a movable rod 52, a second spring 53 and an adjustment disk 54, wherein the mounting platform 51 is fixed to one end of the movable rod 52, the side pressure roller 23 can be rotatably connected to the outside of the mounting platform 51, a mounting hole is opened on the outside of the bracket 31, the movable rod 52 is movably connected to the mounting hole, so that the movable rod 52 can move back and forth, the adjustment disk 54 is threadedly connected to the outside of the movable rod 52, and the second spring 53 is fixedly arranged between the adjustment disk 54 and the bracket 31, and is located on the outside of the movable rod 52.

[0035] When designed in this way, the elastic force of spring 2 53 can be adjusted by rotating the position of the adjusting disk 54 on the movable rod 52 to control the pressing force of the side pressure roller 23 on the belt 1, and the side pressure roller 23 can clean and remove water from the front and rear sides of the belt 1. In this way, the relative dryness of the belt 1 is further ensured, the water stains flowing out of the gaps in the belt conveyor are reduced, and the service life of the belt conveyor is extended.

[0036] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
