A buffer receiving and conveying device for ore

Abstract

This utility model discloses an ore buffer receiving and conveying device, including a housing; and further including: a conveyor belt disposed inside the housing, with a plurality of air storage chambers evenly spaced within the belt wall, and a plurality of exhaust holes evenly spaced on the outer wall of the conveyor belt corresponding to the positions of the air storage chambers; and an air pump fixedly mounted on the outer wall of the housing at the feed end. When this improved ore buffer receiving and conveying device is in use, as fluorite ore falls onto the conveyor belt, the airflow blowing on the fluorite ore cleans up dust and debris, and simultaneously reduces the falling speed of the fluorite ore, thereby reducing the collision force between the fluorite ore and the conveyor belt. After the fluorite ore collides with the conveyor belt, the deformation of the conveyor belt directly offsets the inertial force of the falling fluorite, thus avoiding frequent stretching and contraction of the conveyor belt, extending its service life, and reducing the operating cost of the fluorite ore conveyor.

Description

Technical Field

[0001] This utility model relates to the technical field of ore conveying devices, and in particular to an ore buffer receiving and conveying device. Background Technology

[0002] Ores are aggregates composed of one or more minerals, which can be metallic minerals, non-metallic minerals, etc. Fluorite is one type of ore. Fluorite is an important non-metallic mineral resource, whose main component is calcium fluoride. It is widely used in industry and handicrafts. When mining fluorite, fluorite is generally transported by fluorite transport machines.

[0003] Existing fluorite ore conveyors typically guide the fluorite ore directly to the top side of the conveyor via the hopper. This results in a significant impact force when the fluorite ore comes into contact with the conveyor belt, causing the conveyor belt to stretch slightly. The frequent stretching and contraction of the conveyor belt over a long period of time leads to permanent deformation, reducing its service life and increasing the operating cost of the fluorite ore conveyor. Utility Model Content

[0004] The purpose of this utility model is to provide an ore buffer receiving and conveying device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ore buffer receiving and conveying device, including a shell;

[0006] Also includes:

[0007] The conveyor belt is located inside the outer shell, and its belt wall has a number of air storage chambers equidistantly arranged inside, and the outer wall of the conveyor belt has a number of exhaust holes equidistantly arranged at positions corresponding to the air storage chambers.

[0008] An air pump is fixedly installed on the outer wall of the feed end of the housing. The exhaust end of the air pump is provided with a flow guiding mechanism to guide the gas discharged by the air pump into the corresponding air storage chamber.

[0009] The drive mechanism, located on the housing, is used to drive the conveyor belt to rotate.

[0010] Preferably, the outer wall of the outer shell feed end is provided with an air extraction mechanism for extracting gas from the outer shell feed end;

[0011] The air extraction mechanism includes a storage box located above the air pump and fixedly connected to the outer shell. The air pump has an air inlet end connected to a conduit, and the top end of the conduit is fixedly inserted through the wall of the storage box. Several air extraction pipes are fixedly installed at equal intervals on the storage box and the outer shell, and the air inlet end of each air extraction pipe is located above the conveyor belt.

[0012] Preferably, a filter plate is fixedly installed inside the storage box and is arranged at an angle, with the top end of the conduit and the outlet end of the suction pipe located on both sides of the filter plate.

[0013] Preferably, the driving mechanism includes two driving rods, which are disposed opposite to each other in the conveyor belt, and both ends of the driving rods rotatably penetrate the shell wall of the outer casing. The outer wall of the driving rod is in contact with the inner wall of the conveyor belt. A driver is fixedly installed on the outer wall of the discharge end of the outer casing, and the driving end of the driver is fixedly connected to the corresponding driving rod.

[0014] Preferably, the flow guiding mechanism includes a flow divider shell disposed within the conveyor belt, with its side near the corresponding drive rod and its top side contacting the outer wall of the corresponding drive rod and the inner wall of the conveyor belt, respectively.

[0016] This utility model has the following beneficial effects:

[0017] When this improved ore buffer receiving and conveying device is in use, as the fluorite ore falls onto the conveyor belt, the airflow blowing on the fluorite ore cleans up the dust and debris on the fluorite ore and simultaneously reduces the falling speed of the fluorite ore, thereby reducing the collision force between the fluorite ore and the conveyor belt. After the fluorite ore collides with the conveyor belt, the deformation of the outside of the conveyor belt directly offsets the inertial force of the falling fluorite ore, thus avoiding frequent stretching and contraction of the conveyor belt, extending the service life of the conveyor belt, and reducing the operating cost of the fluorite ore conveyor.

[0025] To make the technical solution and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] This utility model provides a technical solution: (Refer to...) Figure 1 - Figure 5 The present invention discloses an ore buffer receiving and conveying device, including a shell 1;

[0027] Also includes:

[0028] The conveyor belt 2 is located inside the outer shell 1, and a number of air storage chambers 3 are equidistantly opened in the inner wall of the belt. A number of exhaust holes 4 are equidistantly opened on the outer wall of the conveyor belt 2 at positions corresponding to the air storage chambers 3.

[0029] The air pump 5 is fixedly installed on the outer wall of the feed end of the housing 1. The exhaust end of the air pump 5 is provided with a flow guiding mechanism 8, which is used to guide the gas discharged by the air pump 5 into the corresponding air storage chamber 3.

[0030] The drive mechanism 7, which is located on the housing 1, is used to drive the conveyor belt 2 to rotate.

[0031] In this embodiment, when the improved ore buffer receiving and conveying device is used, the air pump 5 is started first, and the gas is continuously injected into the corresponding gas storage chamber 3 through the flow guiding mechanism 8. Since the amount of gas discharged from the exhaust hole 4 is limited, a high-pressure chamber is formed in the gas storage chamber 3 located at the feed end of the outer shell 1. At the same time, the drive mechanism 7 drives the constraint belt to rotate at a constant speed inside the outer shell 1, and the device is started.

[0032] After the device is started, the fluorite ore is transported to the top of the feed end of the outer shell 1 by the external feeding device. During the fall of the fluorite ore, the gas flowing upward continuously from the bottom side of the fluorite ore can continuously exert an upward thrust on the fluorite ore to reduce the falling speed of the fluorite ore, thereby reducing the collision force between the fluorite ore and the conveyor belt 2. At the same time, the airflow blowing on the fluorite ore can also initially clean the dust and debris on the outside of the fluorite ore. When the falling fluorite ore collides with the conveyor belt 2, the top of the conveyor belt 2 bends and deforms, so that some of the gas in the gas storage chamber 3 is accelerated to be discharged. During this process, the high pressure chamber in the gas storage chamber 3 can continuously exert an upward thrust on the falling fluorite ore. With the help of the flow guiding mechanism 8, which supports part of the conveyor belt 2 from inside, the inertial force of the falling fluorite can be directly offset, thereby avoiding frequent stretching and contraction of the conveyor belt 2, extending the service life of the conveyor belt 2, and increasing the service life of the fluorite ore conveyor.

[0033] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 4 and Figure 5 As shown, an air extraction mechanism 6 is provided on the outer wall of the feed end of the outer shell 1 to extract the gas inside the feed end of the outer shell 1.

[0034] The air extraction mechanism 6 includes a storage box 61, which is located above the air pump 5 and fixedly connected to the outer shell 1. The air pump 5 has an air inlet end connected to a conduit 62, and the top end of the conduit 62 is fixedly inserted through the wall of the storage box 61. Several air extraction pipes 63 are fixedly inserted through the storage box 61 and the outer shell 1 at equal intervals, and the air inlet end of each air extraction pipe 63 is located above the conveyor belt 2.

[0035] In this embodiment, please refer to Figure 1 , Figure 4 and Figure 5 As shown, when the air pump 5 starts, it continuously draws gas from the storage tank 61 through the conduit 62, so that a negative pressure chamber is continuously formed in the storage tank 61. At this time, due to the pressure difference between the two ends of the suction pipe 63, the gas in the feed end of the outer shell 1 flows into the storage tank 61 through the suction pipe 63 to replenish the gas in the storage tank 61. At this time, most of the dust and debris blown down from the fluorite ore is sucked into the storage tank 61 along with the airflow to avoid a large amount of dust and debris being scattered in the air near the device.

[0036] In a further preferred embodiment of this utility model, such as Figure 5 As shown, a filter plate 64 is fixedly installed inside the storage box 61 and is arranged at an angle. The top end of the conduit 62 and the air outlet end of the suction pipe 63 are located on both sides of the filter plate 64, respectively.

[0037] In this embodiment, please refer to Figure 5As shown, after dust and debris enter the outer shell 1 of the storage box 61 along with the airflow, they are blocked by the filter plate 64 and stored in the storage box 61. (The storage box 61 is divided into two parts: the box body and the box cover. The bottom end of the box cover is inserted into the top opening of the box body and is fixedly connected to the box body by bolts or buckles.) The box cover and the box body are separated periodically, and the dust and debris in the storage box 61 can be cleaned directly from the top opening of the box body.

[0038] In a further preferred embodiment of this utility model, such as Figure 1 - Figure 4 As shown, the drive mechanism 7 includes two drive rods 71, which are disposed opposite to each other in the conveyor belt 2, and both ends of the drive rods rotatably penetrate the shell wall of the outer casing 1. The outer wall of the drive rod 71 contacts the inner wall of the conveyor belt 2. A driver 72 is fixedly installed on the outer wall of the discharge end of the outer casing 1, and the drive end of the driver 72 is fixedly connected to the corresponding drive rod 71.

[0039] In this embodiment, please refer to Figure 1 - Figure 4 As shown, when the air pump 5 starts, the driver 72 starts synchronously (the driver 72 is mainly composed of the housing 1, the motor and several transmission gears). The started driver 72 drives the corresponding drive rod 71 to rotate. Due to the friction between the drive rod 71 and the inner wall of the conveyor belt 2 and the constraint limit of the drive rod 71 on the constraint belt, the conveyor belt 2 rotates at a constant speed in the housing 1 along a fixed trajectory, thereby moving the fluorite ore of the conveyor belt 2 along a fixed trajectory through the rotating conveyor belt 2.

[0040] In a further preferred embodiment of this utility model, please refer to Figure 2 , Figure 3 and Figure 5 As shown, the flow guiding mechanism 8 includes a flow divider shell 81, which is located inside the conveyor belt 2. The side of the flow divider shell 81 closest to the corresponding drive rod 71 and the top side of the flow divider shell 81 are in contact with the outer wall of the corresponding drive rod 71 and the inner wall of the conveyor belt 2, respectively. The interior of the flow divider shell 81 is connected to the interior of the exhaust end of the air pump 5 through a connecting pipe. A soft mesh plate 82 is fixedly installed through the inner wall of the conveyor belt 2 at the position corresponding to the air storage chamber 3, and the side of the soft mesh plate 82 closest to the inner wall of the conveyor belt 2 is in contact with the inner wall of the conveyor belt 2.

[0041] In this embodiment, please refer to Figure 2 , Figure 3 and Figure 5As shown, the gas discharged by the air pump 5 is directly discharged into the distribution shell 81 through the connecting pipe. Due to the obstruction of the conveyor belt 2 and the soft mesh plate 82 (the soft mesh plate 82 is made of rubber), the gas flowing into the distribution shell 81 will quickly fill the space inside the distribution shell 81. Then the gas flows through the holes of the soft mesh plate 82 into the air storage chamber 3. Without affecting the rotation of the conveyor belt 2, the gas is injected into the air storage chamber 3 located in the air inlet end of the outer shell 1.

[0042] In a further preferred embodiment of this utility model, such as Figure 2 , Figure 3 and Figure 5 As shown, a rigid mesh plate 83 is fixedly installed inside the top opening of the diversion shell 81, and the top side of the rigid mesh plate 83 is coplanar with the top side of the diversion shell 81.

[0043] In this embodiment, please refer to Figure 2 , Figure 3 and Figure 5 As shown, the rigid mesh plate 83 (made of stainless steel) can support part of the conveyor belt 2 from inside without affecting the flow of gas into the gas storage chamber 3 from inside the diversion shell 81, and at the same time, it will not affect the gas pump 5 from injecting gas into the gas storage chamber 3.

[0044] Working principle: When this improved ore buffer receiving and conveying device is used, the air pump 5 is started first, and the gas in the storage tank 61 is continuously drawn through the conduit 62 so that a negative pressure chamber is continuously formed in the storage tank 61. At this time, due to the pressure difference between the two ends of the air extraction pipe 63, the gas in the feed end of the outer shell 1 flows into the storage tank 61 through the air extraction pipe 63 to replenish the gas in the storage tank 61. At the same time, the gas drawn by the air pump 5 is continuously injected into the diversion shell 81 through the connecting pipe. Due to the obstruction of the hard mesh plate 83 and the soft mesh plate 82, the gas flowing into the diversion shell 81 will quickly fill the space in the diversion shell 81. Then the gas flows into the air storage chamber 3 in the feed end of the outer shell 1 through the holes of the hard mesh plate 83 and the soft mesh plate 82. Since the amount of gas discharged at the exhaust hole 4 is limited, a high pressure chamber is formed in the air storage chamber 3 located at the feed end of the outer shell 1.

[0045] At the same time as the air pump 5 starts, the starting driver 72 drives the corresponding drive rod 71 to rotate. Due to the friction between the drive rod 71 and the inner wall of the conveyor belt 2 and the constraint limit of the drive rod 71 on the constraint belt, the conveyor belt 2 rotates at a constant speed along a fixed trajectory inside the outer shell 1, and the device starts up.

[0046] After the device is started, the fluorite ore is transported to the top of the feed end of the outer shell 1 by an external feeding device or manually by a shovel. The fluorite is poured into the feed end of the outer shell 1. During the falling of the fluorite ore, the gas flowing upward continuously from the bottom side of the fluorite ore can continuously exert an upward thrust on the fluorite ore to reduce the falling speed of the fluorite ore, thereby reducing the collision force between the fluorite ore and the conveyor belt 2. At the same time, the airflow blowing on the fluorite ore can also initially clean the dust and debris on the outside of the fluorite ore. The dust and debris blown down then enter the storage box 61 along with the airflow. Due to the connection of the filter plate 64 to the dust and debris, the dust and debris are trapped and stored in the storage box 61.

[0047] Regularly disassemble the lid and body of the box to clean the dust and debris inside the storage box 61 directly through the top opening of the box body;

[0048] When the falling fluorite ore collides with the conveyor belt 2, the top of the conveyor belt 2 bends and deforms due to the internal support of the diversion shell 81 and the rigid mesh plate 83, so that some of the gas in the gas storage chamber 3 is accelerated to be discharged. During this process, the high-pressure chamber in the gas storage chamber 3 can continuously apply an upward thrust to the falling fluorite ore, thereby directly offsetting the inertial force of the falling fluorite ore, so as to avoid the diversion shell 81 and the rigid mesh plate 83 from vibrating due to the collision between the falling fluorite and the conveyor belt 2, and transmitting the vibration to the outer shell 1.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
