Description

Technical Field

[0001] The invention relates to the technical field of weighing devices, in particular to a feeding weighing device for ferromolybdenum smelting. Background Art

[0002] Electronic belt scale is one of the commonly used weighing devices in molybdenum iron smelting. It can cooperate with the belt conveyor to dynamically weigh the raw materials during material transportation. When the materials are transported on the belt conveyor, the weighing sensor on the weighing bridge detects the weight signal of the materials on the belt, and the speed sensor detects the running speed signal of the belt. These two signals are transmitted to the weighing display, and the instantaneous flow rate and cumulative weight of the materials are obtained through calculation and processing.

[0003] In the raw material measurement of ferromolybdenum smelting, for larger-scale raw material purchases and usage, tons are usually used for measurement. For example, the purchase volume of molybdenum concentrate, iron powder, etc. may be calculated in several tons or dozens of tons. For some raw materials with larger volume but relatively smaller density, such as the stacking volume of certain block materials, it may be measured in cubic meters. It can be seen that the quality of the mixed raw materials is extremely high.

[0004] In the weighing process of feeding materials for ferromolybdenum smelting, the existing technology usually directly guides the mixed raw materials to the conveyor belt, and then weighs them through an electronic belt scale. Due to the large amount of raw materials used, this method is easy to cause concentrated accumulation on the conveyor belt during feeding or cause single-point impact on the conveyor belt. Concentrated accumulation or single-point impact will cause uneven local force on the belt, so that the weight sensed by the weighing sensor is different from the actual weight of the material passing through the belt, thereby affecting the accuracy of the measurement. Concentrated accumulation or single-point impact will cause drastic fluctuations in the output signal of the weighing sensor, making it difficult for the control system to accurately obtain stable weighing data, affecting the control and regulation of the production process, and causing large errors in the weighing results. Strong single-point impact and uneven concentrated accumulation may cause excessive pressure and wear on the belt, weighing sensor and other mechanical components, shorten the service life of the equipment, and may even cause component damage.

[0005] Therefore, the present invention provides a thermal testing device that can avoid concentrated accumulation of raw materials on a conveyor belt during loading and reduce single-point impact on the conveyor belt caused by excessive use of raw materials. Summary of the invention

[0012] Furthermore, a protective shell is installed on one side of the discharge shell that passes through the transmission rod, the bottom of the protective shell is fixed to one side of one of the brackets, and two clamps are welded on the other two sides of the discharge shell respectively. L-shaped frames are fixed on the outer sides of the four clamps, and a guide plate is welded to the inner side of the bottom of the discharge shell, and the other end of the guide plate is located on the inner side of the conveyor belt.

[0013] Furthermore, the chute shell is welded to the top of the discharge shell, and the guide frame is fixed to the inner side of the chute shell.

[0014] Furthermore, a resisting assembly is arranged at the top of the guide frame, and is assembled to offset the initial impact of the falling raw materials through the elastic force of the spring.

[0016] Beneficial effects of the present invention:

[0017] The feeding and weighing device for ferromolybdenum smelting described in the present invention adopts a resisting component. When the raw material impacts the top plate, the special-shaped plate decomposes the impact force into a force for pushing the special-shaped plate to rotate and a force for pressing the top plate downward by relying on its own inclined surface. The main spring and the auxiliary spring can support the top plate upward and then offset the decomposed force for pressing the top plate downward. While driving the top plate to rotate, the decomposed force for pushing the special-shaped plate to rotate is unloaded, so that most of the impact force carried by the raw material itself is decomposed, offset and unloaded. After the top plate rotates to throw the raw material out from the top of the top plate, it is re-gathered under the action of a guide frame and then moved to the top of the baffle under the action of gravity. In this process, the guide frame not only plays a guiding role, but also can reduce the impact force of the raw material falling again. Finally, due to the existence of the baffle, the impact force carried by the raw material itself will be weakened again. Compared with the prior art, the impact force carried by the raw material itself is offset three times, which greatly reduces the impact on the conveyor belt, avoids the single-point impact of the raw material on the conveyor belt, and thus will not affect the auxiliary roller and the electronic belt scale, thereby improving the weighing effect.

[0018] The present invention discloses a feeding and weighing device for ferromolybdenum smelting, in which the transmission gear drives the transmission rod to rotate through a toothed chain and a driven gear, the transmission rod drives the main shaft to rotate through bevel gears one and two, the main shaft drives the scraper to scrape the raw materials on the top of the baffle plate to the inner side of the guide plate in batches, and enters the belt under the guidance of the guide plate. When the belt drives the raw materials to move the top of the weighing roller, the electronic belt scale weighs the raw materials and then transports them to the feed port, so that the raw materials are dispersed, thereby avoiding the concentrated accumulation of raw materials on the conveyor belt and reducing the impact on the electronic belt scale.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Example

[0032] like Figure 1-Figure 10 As shown, a charging and weighing device for molybdenum iron smelting described in the present invention includes two brackets 11, wherein a motor 12 is fixed on the side of one bracket 11 opposite to the other bracket 11, an active roller 13 is rotatably installed through the side opposite to each other at both ends of the two brackets 11, and an electronic conveyor belt 16 scale is fixed on the inner side of the two brackets 11.

[0033] Specifically, a driven roller 15 is rotatably installed on the inner side of the two brackets 11, two groups of auxiliary rollers 14 are fixed on the top of the two brackets 11, and each group consists of four auxiliary rollers 14. Three weighing rollers 21 are fixed on the top of the electronic conveyor belt 16 scale, and the three weighing rollers 21 are located on the side close to the two groups of auxiliary rollers 14. The outer sides of the driven roller 15, the two active rollers 13, the three weighing rollers 21 and the two groups of auxiliary rollers 14 are covered with a conveyor belt 16.

[0034] In this embodiment, the motor 12 can drive the conveyor belt 16 to rotate through the active roller 13. The driven roller 15, two active rollers 13, three weighing rollers 21 and two groups of auxiliary rollers 14 are all used to support the conveyor belt 16. There are multiple driven rollers 15. The motor 12 drives the conveyor belt 16 to rotate along the outer sides of the driven roller 15, two active rollers 13, three weighing rollers 21 and two groups of auxiliary rollers 14 through the active roller 13 connected to the output end of the motor 12, so that the conveyor belt 16 can transport the raw materials to the feeding end.

[0035] Specifically, one end of the active roller 13 is fixed to the output end of the motor 12 , and an extension rod 131 is welded to the other end of the active roller 13 , and a transmission gear 132 is fixed to the outer side of the extension rod 131 .

[0036] In this embodiment, when the motor 12 drives the belt to rotate through the active roller 13 , the active roller 13 connected to the motor 12 drives the transmission gear 132 to rotate through the extension rod 131 .

[0037] Specifically, the chute housing 5 is disposed on the top of the discharge housing 61 and is configured to regroup the raw materials dispersed by the resisting assembly 7 through the guide frame 51;

[0038] The material distribution assembly 6 is arranged on the top of the two brackets 11, and is equipped to push the raw materials on the top of the baffle 65 to the top of the guide plate 62 through the scraper 67, and then the guide plate 62 guides the raw materials out of the discharge shell 61;

[0039] The material distribution component 6 also includes a toothed chain 68, one end of the toothed chain 68 is meshedly connected to the outer side of the transmission gear 132, and the other end of the toothed chain 68 is meshedly connected to the inner side of the driven gear 631, a transmission rod 63 is fixed to the inner side of the driven gear 631, and a bevel gear 2 632 is fixed to the outer side of the other end of the transmission rod 63, and a discharging shell 61 is installed on the outer side of the transmission rod 63 through a bearing, and baffles 65 are welded to the inner walls on both sides of the opposite sides of the discharging shell 61, and a main shaft 66 is installed at the bottom of the baffle 65 through a bearing, a scraper 67 is fixed to the outer side of one end of the main shaft 66 located at the top of the baffle 65, and a bevel gear 1 661 is fixed to the outer side of one end of the main shaft 66 located at the bottom of the baffle 65, and the bevel gear 1 661 is meshed with the bevel gear 2 632, and a protective box 64 is installed at the bottom of the baffle 65, and the bevel gear 1 661 and the bevel gear 2 632 are located on the inner side of the protective box 64.

[0040] In this embodiment, the transmission gear 132 drives the transmission rod 63 to rotate through the tooth chain 68 and the driven gear 631, and the transmission rod 63 drives the main shaft 66 to rotate through the bevel gear 1 661 and the bevel gear 2 632. The main shaft 66 drives the scraper 67 to scrape the raw material on the top of the baffle 65 to the inner side of the guide plate, and enters the belt under the guidance of the guide plate. When the belt drives the raw material to move the top of the weighing roller 21, the electronic belt scale 2 weighs the raw material and transports it to the feed port. Due to the existence of the baffle 65, the impact force carried by the raw material itself will be weakened again, and then the impact force carried by the raw material itself after being pushed to the guide plate by the scraper 67 will be offset three times, which greatly reduces the impact on the conveyor belt 16 and reduces the shaking of the conveyor belt 16, and thus will not affect the auxiliary roller 14 and the electronic belt scale 2, thereby improving the weighing effect.

[0041] Specifically, a protective shell 69 is installed on one side of the discharge shell 61 that passes through the transmission rod 63, and the bottom of the protective shell 69 is fixed to one side of one of the brackets 11. Two clamping plates 611 are welded to the other two sides of the discharge shell 61 respectively, and L-shaped frames 3 are fixed to the outer sides of the four clamping plates 611. The guide plate 62 is welded to the inner side of the bottom of the discharge shell 61, and the other end of the guide plate 62 is located on the inner side of the conveyor belt 16.

[0042] In this embodiment, the protective shell 69 is mainly used to protect the toothed chain 68, the transmission gear 132 and the driven gear 631, ensuring their meshing state so that they can effectively transmit and avoid external impact.

[0043] Specifically, the chute shell 5 is welded to the top of the discharge shell 61 , and the guide frame 51 is fixed to the inner side of the chute shell 5 .

[0044] In this embodiment, after the top plate 74 rotates to throw the raw materials out from the top of the top plate 74, they are re-gathered under the action of the guide frame 51 and move to the top of the baffle 65 under the action of gravity. In this process, the guide frame 51 not only plays a guiding role, but also can reduce the impact force of the falling raw materials again.

[0045] Specifically, the resisting assembly 7 is arranged at the top of the guide frame 51, and is equipped to offset the initial impact of the falling raw material through the elastic force of the spring. The resisting assembly 7 includes four corner frames 71, which are welded to the top of the guide frame 51, and the four corner frames 71 are located at the four corners of the top of the guide frame 51. The inner sides of the four corner frames 71 are welded with support rings 72, and the inner sides of the support rings 72 are connected with a turntable 73 through a bearing clamp. The top of the turntable 73 is fixed with a main spring, and the other end of the main spring is fixed with a top plate 74. Four auxiliary springs are fixed on the top of the top plate 74, and the tops of the four auxiliary springs are fixed to the bottom of the top plate. The bottom of the top plate 74 is welded with a main rod 76, and the other end of the main rod 76 is located at the bottom of the turntable 73. Four slave rods 77 are welded to the bottom of the top plate 74, and the other ends of the four slave rods 77 are located at the bottom of the turntable 73. A plurality of special-shaped plates 75 are installed on the top of the top plate 74, and the number of the special-shaped plates 75 is ≥10, and the outer edge of each special-shaped plate 75 is arc-shaped, which can also reduce the impact force of the falling raw materials and reduce the splashing of the raw materials.

[0046] Specifically, a receiving shell 4 is installed on the top of the chute shell 5 , and two fixing plates 41 are welded on opposite sides of the receiving shell 4 . The four fixing plates 41 are fixedly connected to the inner sides of the four L-shaped frames 3 , respectively.

[0047] In this embodiment, after the staff crushes and grinds the molybdenum concentrate, they mix the molybdenum concentrate with other auxiliary materials (such as iron powder, ferrosilicon, etc.) in a certain proportion according to actual production needs, and then guide the mixed raw materials to the inner side of the receiving shell 4 through other equipment, and start the motor 12 and the electronic belt scale 2 at the same time. The raw materials will cause impact on the top plate 74 under the action of gravity and inertia. The special-shaped plate 75 relies on its own inclined surface to decompose the impact force into a force that pushes the special-shaped plate 75 to rotate and a force that presses the top plate 74 downward. The main spring and the auxiliary spring can support the top plate 74 upward and then offset the decomposition force that presses the top plate 74 downward. The main rod 76 and the slave rod 77 ensure that the top plate 74 will not tilt under the action of the turntable 73 and the support ring 72. Multiple special-shaped plates 75 drive the top plate 74 to rotate, throw the raw materials out from the top of the top plate 74, and remove the decomposition force that pushes the special-shaped plate 75 to rotate, so that most of the impact force carried by the raw materials themselves is decomposed, offset and removed.

[0048] Working principle: The initial state is as follows Figure 1-Figure 10As shown, after the staff crushes and grinds the molybdenum concentrate, they mix the molybdenum concentrate with other auxiliary materials (such as iron powder, ferrosilicon, etc.) in a certain proportion according to actual production needs, and then guide the mixed raw materials to the inner side of the receiving shell 4 through other equipment, and start the motor 12 and the electronic conveyor belt 16 at the same time, the raw materials move to the top of the top plate 74, and then the raw materials are thrown out from the top of the top plate 74, and under the action of the guide frame 51, they are re-converged and moved to the top of the baffle 65. The motor 12 drives the conveyor belt 16 through the active roller 13 along the driven roller 15, two active rollers 13, three weighing rollers 21 and two sets of The outer side of the auxiliary roller 14 rotates, and at the same time, the active roller 13 connected to the motor 12 drives the transmission gear 132 to rotate through the extension rod 131. The transmission gear 132 drives the transmission rod 63 to rotate through the tooth chain 68 and the driven gear 631. The transmission rod 63 drives the main shaft 66 to rotate through the bevel gear 1 661 and the bevel gear 2 632. The main shaft 66 drives the scraper 67 to scrape the raw materials on the top of the baffle 65 to the inner side of the guide plate, and enters the conveyor belt 16 under the guidance of the guide plate. When the conveyor belt 16 drives the raw materials to move to the top of the weighing roller 21, the electronic conveyor belt 16 scale weighs the raw materials and transports them to the feed port.
