Description

Technical Field

[0001] This invention relates to the field of conveying mechanism technology, specifically to an anti-drop conveying mechanism for diverting sand products. Background Technology

[0002] Drainage sand is a key refractory material used in the bottom nozzle of steel ladles during steel smelting. Its main function is to ensure that molten steel can flow out automatically and smoothly during the pouring process, thereby improving production efficiency and safety. It is usually composed of a mixture of various high-temperature resistant mineral materials, with common components including magnesium olivine, fused magnesia, chromite sand, and quartz sand.

[0003] In large-scale industrial production, multiple sets of agitated tanks are usually set up to process simultaneously. After processing, the multiple sets of agitated tanks arranged side by side discharge the sand onto the conveyor belt for unified transportation. In traditional conveyor belt mechanisms, the sand is prone to falling and spilling during the discharge and transportation process. Since the conveyor belt is in operation, the traditional method of directly setting up a cover to block the sand results in relative movement between the cover and the conveyor belt, which is prone to wear and causes significant damage to the conveyor belt. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-drop conveying mechanism for diverting sand products, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an anti-drop conveying mechanism for diverting sand products, comprising a conveyor frame, a bending roller shaft mounted on the conveyor frame, and a conveyor belt, wherein the two sides of the conveyor belt are folded upwards to form a U-shape by the support of the bending roller shaft; the anti-drop conveying mechanism further comprises:

[0006] The anti-fall cover is used to block the guide sand and prevent the guide sand conveyed on the conveyor belt from falling off. The two sides of the anti-fall cover are bent downward and overlap and contact the two sides of the conveyor belt that are folded upward.

[0007] Airflow slots are formed on the two downwardly bent surfaces of the anti-fall shield. The airflow slots are set parallel to the length direction of the anti-fall shield. Positive pressure airflow is ejected through the airflow slots, so that the airflow enters between the contact surface between the conveyor belt and the anti-fall shield.

[0008] The anti-fall shield is provided with a flow equalization pipe, which is parallel to and corresponds to the airflow slot and is interconnected with it;

[0009] The upper part of the anti-fall shield is provided with a negative pressure top chamber, the bottom of the negative pressure top chamber is provided with a mesh bottom plate, and a filter layer is attached to the lower surface of the mesh bottom plate. The negative pressure top chamber is connected to the inner cavity of the anti-fall shield, and the gas entering the negative pressure top chamber from the anti-fall shield can be filtered through the filter layer.

[0010] An air pump module is fixedly installed on the perforated bottom plate. The air pump module can drive the perforated bottom plate to resonate and draw gas from the negative pressure top chamber into the flow equalization pipe.

[0011] The air outlet of the air pump module is connected to a corrugated connecting pipe, a top pipe is connected to the corrugated connecting pipe, a diversion pipe is connected to the top pipe, a side wall air pipe is attached to the surface of the anti-fall shield, and the diversion pipe is connected to the flow equalization pipe through the side wall air pipe.

[0012] An extension shaft is coaxially fixed on the motor shaft of the air pump module, and a track frame is fixedly installed on the surface of the extension shaft.

[0013] A counterweight is provided on the outside of the extension shaft. A track side groove is formed on the surface of the counterweight. The track outer frame is limited in the track side groove, so that the counterweight slides radially along the extension shaft.

[0014] An adjusting screw is inserted into the counterweight, and the adjusting screw is screwed into the counterweight. The movement of the counterweight is controlled by rotating the adjusting screw.

[0015] The extension shaft has a control shaft cavity, in which a gear disk and a rack plate are disposed. The gear disk is fixed coaxially with the adjusting screw, and the gear disk and the rack plate mesh with each other. When the rack plate moves along the axial direction of the extension shaft, the gear disk rotates.

[0016] A driven cavity tube is fixedly provided at the end of the extension shaft, and a driving piston is provided in the driven cavity tube. The driven cavity tube and the driving piston are in sealed contact. A piston shaft is fixedly provided on the driving piston, and one end of the piston shaft is fixedly installed with a rack plate.

[0017] A pressure equalization hole is provided through the side surface of the driven cavity tube facing the extension shaft. An interactive rotating tube is coaxially provided on the side of the driven cavity tube away from the extension shaft. A sealing sleeve is provided on the surface of the interactive rotating tube. A stabilizing frame is fixedly provided on the outside of the sealing sleeve. The sealing sleeve is fixedly installed with the air pump module through the stabilizing frame. A medium pipe is connected to the sealing sleeve. The medium pipe is connected to the inner cavity of the driven cavity tube through the interactive rotating tube.

[0018] The surface of the negative pressure top chamber is provided with an annular pressure sensing ring, and a floating plug is provided in airtight contact within the annular pressure sensing ring. Below the floating plug is a support spring that applies an upward supporting force to the floating plug.

[0019] A central tube is provided at the center of the floating plug disc, and a central piston is provided in the central tube. The central piston and the central tube are in sealed contact. A straight shaft tube is fixedly provided at the lower part of the central piston. The lower end of the straight shaft tube is connected to the medium pipeline, and the upper end of the straight shaft tube is connected to the upper surface of the central piston. Thus, when the central piston moves upward relative to the central tube, the medium in the central tube can enter the medium pipeline through the straight shaft tube.

[0020] A roller support is fixedly installed on the conveyor frame, and the bending roller is rotatably mounted on the roller support. The roller support supports and limits the bending roller. Drive belt rollers are respectively installed at both ends of the conveyor frame to support and tension the conveyor belt.

[0021] The upper part of the anti-fall shield is connected to a product input cover. After the sand is processed, it is fed into the conveyor belt above the product input cover for conveying.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] The anti-fall conveying mechanism of this invention, through the setting of an anti-fall shield, can prevent the guide sand from falling during the process of being added to the top of the conveyor belt and during the conveying process; and through the setting of airflow slots, airflow can be introduced between the overlapping contact surfaces of the conveyor belt and the anti-fall shield, forming an air film between the contact surfaces of the conveyor belt and the anti-fall shield, reducing contact wear between the two and reducing friction, thus saving energy; at the same time, since the contact surfaces of the conveyor belt and the anti-fall shield are under positive pressure, it can inhibit the entry of guide sand and dust, not only enhancing the shielding and sealing effect of the guide sand, but also reducing the aggravation of wear caused by the guide sand entering the contact surfaces.

[0024] By combining the negative pressure top chamber, air pump module, and mesh bottom plate, the air supply to the airflow slots can keep the inside of the anti-fall shield under negative pressure, reducing dust escape. At the same time, the vibration of the air pump module drives the mesh bottom plate and filter layer to vibrate, making the filter layer less prone to clogging and reducing maintenance frequency.

[0025] By using a combination of counterweights, driven chamber tubes, and annular pressure-sensing rings, the air pump module can automatically adjust its amplitude according to the degree of clogging in the filter layer. The more severe the clogging, the greater the negative pressure inside the negative pressure top chamber. At this time, the automatic adjustment of the structure increases the amplitude of the vibration caused by the air pump module, thereby enhancing the vibration cleaning effect on the filter layer. Conversely, when the degree of clogging in the filter layer is low, the amplitude of the vibration caused by the air pump module is low, thus slowing down the metal fatigue rate of structures such as the mesh bottom plate.

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 9 This invention provides a technical solution: an anti-drop conveying mechanism for diverting sand products, comprising a conveyor frame 1, a bending roller 2 mounted on the conveyor frame 1, and a conveyor belt 3. Supported by the bending roller 2, the two sides of the conveyor belt 3 are folded upwards to form a U-shape, as shown below. Figure 1 As shown, the bending roller 2 includes a horizontally arranged roller and an inclined roller, and the inclined roller causes the two sides of the conveyor belt 3 to be folded upwards;

[0038] The anti-fall conveyor mechanism also includes: an anti-fall shield 4, which is used to shield the guiding sand and prevent the guiding sand conveyed on the conveyor belt 3 from falling off. The two sides of the anti-fall shield 4 are bent downwards and overlap with the two sides of the conveyor belt 3 that are folded upwards. Figure 4 As shown, the two sides of the anti-fall shield 4 press against the two sides of the conveyor belt 3 that are folded upwards;

[0039] Airflow slots 5 are formed on the two downwardly bent surfaces of the anti-fall shield 4. The airflow slots 5 are set parallel to the length direction of the anti-fall shield 4. Positive pressure airflow is ejected through the airflow slots 5, so that the airflow enters the contact surface between the conveyor belt 3 and the anti-fall shield 4.

[0040] The anti-fall shield 4 is equipped with a flow equalization pipe 501, which is parallel to and connected to the airflow slot 5. The flow equalization pipe 501 enables the airflow slot 5 to exhaust gas evenly. The upper part of the anti-fall shield 4 is equipped with a negative pressure top chamber 502, and the bottom of the negative pressure top chamber 502 is equipped with a mesh bottom plate 503. The lower surface of the mesh bottom plate 503 is covered with a filter layer 504. The negative pressure top chamber 502 is connected to the inner cavity of the anti-fall shield 4. The filter layer 504 can filter the gas entering the negative pressure top chamber 502 from the anti-fall shield 4. An air pump module 505 is fixedly installed on the mesh bottom plate 503. The air pump module 505 includes a pump body and a motor. The air pump module 505 can drive the mesh bottom plate 503 to resonate and draw gas from the negative pressure top chamber 502 into the flow equalization pipe 501.

[0041] The air pump module 505 is connected to a corrugated connecting pipe 506 at its outlet, allowing the air pump module 505 to vibrate relative to the negative pressure top chamber 502. A top pipe 507 is connected to the corrugated connecting pipe 506, and a diversion pipe 508 is connected to the top pipe 507. A side wall air pipe 509 is attached to the surface of the anti-fall shield 4, and the diversion pipe 508 is connected to the flow equalization pipe 501 through the side wall air pipe 509.

[0042] like Figure 6 and Figure 9 As shown, an extension shaft 510 is coaxially fixed on the motor shaft of the air pump module 505, and a track frame 511 is fixedly installed on the surface of the extension shaft 510; a counterweight 512 is provided on the outside of the extension shaft 510, and a track side groove 513 is opened on the surface of the counterweight 512. The track frame 511 is limited in the track side groove 513, so that the counterweight 512 slides radially along the extension shaft 510.

[0043] An adjusting screw 514 is inserted into the counterweight 512. The adjusting screw 514 is screwed into the counterweight 512, and the movement of the counterweight 512 is controlled by the rotation of the adjusting screw 514.

[0044] The extension shaft 510 has a control shaft cavity 515, in which a gear disk 516 and a rack plate 517 are provided. The gear disk 516 is coaxially fixed with the adjusting screw 514, and the gear disk 516 and the rack plate 517 mesh with each other. When the rack plate 517 moves along the axial direction of the extension shaft 510, the gear disk 516 rotates.

[0045] The end of the extension shaft 510 is fixedly provided with a driven cavity tube 518, and a driving piston 519 is provided in the driven cavity tube 518. The driven cavity tube 518 and the driving piston 519 are in sealed contact. A piston shaft 520 is fixedly provided on the driving piston 519, and one end of the piston shaft 520 is fixedly installed with the rack plate 517.

[0046] A pressure equalization hole 521 is provided through the side surface of the driven cavity tube 518 facing the location of the extension shaft 510. An alternating rotating tube 522 is coaxially arranged on the side of the driven cavity tube 518 away from the location of the extension shaft 510. A sealing sleeve 523 is provided on the surface of the alternating rotating tube 522. Figure 9 As shown, the interactive rotating tube 522 and the sealing rotating sleeve 523 can rotate relative to each other, and the sealing rotating sleeve 523 and the interactive rotating tube 522 maintain a sealed connection. A stabilizing frame 524 is fixedly installed on the outside of the sealing rotating sleeve 523. The sealing rotating sleeve 523 is fixedly installed with the air pump module 505 through the stabilizing frame 524. A medium pipe 525 is connected to the sealing rotating sleeve 523. The medium pipe 525 is connected to the inner cavity of the driven cavity tube 518 through the interactive rotating tube 522.

[0047] The surface of the negative pressure top chamber 502 is provided with an annular pressure sensing ring 526, and a floating plug 527 is provided in airtight contact within the annular pressure sensing ring 526. Below the floating plug 527, a support spring 528 is provided to apply an upward supporting force to the floating plug 527.

[0048] A central tube 529 is located at the center of the floating plug disc 527, and a central piston 530 is installed inside the central tube 529. The central piston 530 and the central tube 529 are in sealed contact. A straight-through shaft tube 531 is fixedly installed at the lower part of the central piston 530. Figure 8 As shown, the straight shaft tube 531 is fixedly installed on the inner wall surface of the annular pressure sensing ring 526 through a bracket, thereby ensuring that the height of the central piston 530 remains unchanged when the floating piston disc 527 moves up and down.

[0049] The lower end of the straight shaft tube 531 is connected to the medium pipeline 525, and the upper end of the straight shaft tube 531 is connected to the upper surface of the central piston 530. Thus, when the central piston 530 moves upward relative to the central tube 529, the medium in the central tube 529 can enter the medium pipeline 525 through the straight shaft tube 531. The medium can be air or hydraulic oil.

[0050] A roller support 101 is fixedly installed on the conveyor frame 1, and a bending roller 2 is rotatably installed on the roller support 101. The roller support 101 supports and limits the bending roller 2. Drive belt rollers 102 are respectively installed at both ends of the conveyor frame 1. The drive belt rollers 102 support and tension the conveyor belt 3.

[0051] The upper part of the anti-fall cover 4 is connected to the product input cover 401. After the sand is processed, it is fed into the conveyor belt 3 through the product input cover 401 for conveying.

[0052] In use, the anti-fall conveyor mechanism of the present invention is driven by a motor or other equipment to rotate the drive roller 102, which in turn drives the conveyor belt 3 to rotate and transport materials. Figure 1 As shown, the conveyor belt 3 is a ring-shaped rubber belt. When the conveyor belt 3 reaches the position of the bending roller shaft 2, the two sides of the conveyor belt 3 fold upwards to form a U-shape, supported by the bending roller shaft 2. At this time, the two sides of the anti-fall shield 4, which bend downwards, overlap and contact the U-shape, thus achieving shielding and protection. The product input cover 401 is connected to the production equipment of the diverting sand, such as a mixing tank. The completed diverting sand product is discharged onto the conveyor belt 3 through the product input cover 401 and discharged through one end by the operation of the conveyor belt 3.

[0053] like Figure 4 As shown, the air pump module 505 operates, drawing gas from the negative pressure top chamber 502 and inputting it into the corrugated connecting pipe 506. The gas then sequentially passes through the top pipe 507, the diversion pipe 508, and the side wall air pipe 509 into the flow equalization pipe 501, causing positive pressure airflow from the airflow slot 5. This positive pressure airflow intervenes between the contact surfaces of the conveyor belt 3 and the anti-fall shield 4, forming an air film, reducing contact wear and friction, and improving energy efficiency. Simultaneously, because the contact surfaces of the conveyor belt 3 and the anti-fall shield 4 are under positive pressure, it can suppress the entry of sand and dust. Figure 4 As shown, when the airflow is ejected through the airflow slot 5, the airflow is split to both sides between the contact surfaces of the conveyor belt 3 and the anti-fall shield 4. Part of the airflow returns to the interior of the anti-fall shield 4, and the other part of the airflow is discharged to the outside. Since the airflow ejected through the airflow slot 5 does not completely return to the anti-fall shield 4, the airflow rate of the negative pressure top chamber 502 to the anti-fall shield 4 is greater than the return flow rate of the airflow ejected from the airflow slot 5. This makes the closed structure formed by the conveyor belt 3 and the anti-fall shield 4 in a negative pressure state, thereby inhibiting the dust from being discharged to the outside of the conveyor belt 3 and the anti-fall shield 4.

[0054] During the operation of the air pump module 505, the air pump module 505 can drive the mesh base plate 503 and the filter layer 504 to vibrate, thereby achieving automatic cleaning of the filter layer 504, making the filter layer 504 less prone to clogging and reducing the frequency of maintenance.

[0055] like Figure 8 and Figure 9As shown, the extension shaft 510 is fixedly installed on the motor shaft of the drive motor of the air pump module 505. When the air pump module 505 is running, the extension shaft 510 rotates synchronously. The counterweight block 512, as an eccentric counterweight structure, can cause the extension shaft 510 and the air pump module 505 to vibrate during the rotation of the extension shaft 510. When the filter layer 504 becomes blocked, the air pump module 505 pumps air, increasing the internal negative pressure of the negative pressure top chamber 502. At this time, the floating plug disc 527 moves downward under the negative pressure drive, compressing the support spring 528 until balance is reached. The central piston 530 moves upward relative to the central tube 529, allowing the medium in the central tube 529 to enter through the medium pipe 525 and the interactive rotating pipe 522. The driven piston 519 in the driven chamber 518 is pushed to move. At this time, the driven piston 519 drives the rack plate 517 to move to the left through the piston shaft 520. Through the meshing of the gear disk 516 and the rack plate 517, the gear disk 516 rotates, and the synchronous adjusting screw 514 rotates, which can drive the counterweight 512 to move upward relative to the outer frame of the track 511, so that the counterweight 512 moves away from the extension shaft 510. When the rotation speed of the extension shaft 510 is inconvenient, the amplitude of the vibration of the extension shaft 510 caused by the counterweight 512 is greatly increased.

[0056] Conversely, when the filter layer 504 is less clogged, the counterweight 512 moves closer to the extension shaft 510 to reduce the vibration amplitude of the extension shaft 510. This allows the device to automatically increase the amplitude when the filter layer 504 is severely clogged, thereby improving the vibration cleaning effect on the filter layer 504. When the filter layer 504 is not severely clogged, the amplitude is automatically reduced to slow down the metal fatigue rate and operating noise of components such as the mesh bottom plate 503.
