Description

Technical Field

[0001] The invention relates to the technical field of barite powder production equipment, and in particular to a large stone jaw crusher for barite powder production. Background Art

[0002] Barite powder, also known as barium sulfate powder, has a chemical composition of BaSO4, and its crystals belong to sulfate minerals of the orthorhombic (orthorhombic) system. It is often in the form of thick plate or columnar crystals, mostly dense blocks or plate-like or granular aggregates. Plate-like crystals have low hardness, complete cleavage at nearly right angles, high density, and no foaming when exposed to hydrochloric acid, which distinguishes it from similar calcite. Barite is mainly formed under medium and low temperature hydrothermal conditions. There are huge barite veins in Shaanxi, Hunan, Guizhou, Guangxi, Qinghai, Xinjiang and other places in China. Barite is the raw material for extracting barium. It can be ground into fine powder and used as a mud weighting agent for drilling. It can be broken into pieces to replace stones as materials for radiation-proof gravity walls. It can also be used as various white pigments, coatings, fillers and chemicals in the rubber and paper industries.

[0003] In the production process of barite powder, the barite ore is processed through crushing and grinding to obtain a powdery substance. A crushing device is usually used in the crushing process. When the traditional jaw crusher is used for coarse crushing, there are problems in the processing process. If the feeding is uneven or the feeding particle size is too large, it is easy to cause uneven crushing and large size difference. In addition, some barite ore may be over-crushed to produce too much fine powder. As the machine runs, smoke and dust are generated, resulting in dust pollution. The material inside the crushing chamber is in a state of high-speed movement and strong impact. If the protective device of the equipment is not perfect, or the operator violates the regulations, such as opening the protective door when the equipment is running, reaching into the crushing chamber, etc., the operator may be hit by the splashing material or pinched by equipment parts, which poses a great safety risk. Based on this, a large stone jaw crusher for barite powder production is proposed. Summary of the invention

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the device is in use, the operator puts the barite that has been initially broken after mining into the inner side of the inner frame through the conveying device. When the equipment is started, the dual output shaft motor rotates to drive the output shaft rod to rotate, and drives the driven inertia transmission disk through the transmission belt, thereby applying rotation to the eccentric drive shaft, and applying reciprocating motion to the active jaw crusher assembly through the eccentric drive shaft. Then, the servo motor starts to drive the rotating shaft to rotate, and drives the articulated seat, articulated rod and striking hammer to rotate. Then the barite is on the inner side of the inner frame. At this time, the electric-controlled telescopic rod is started to retract, prompting the two closed arc-shaped closing gates to slide and generate a gap under the support of the arc-shaped guide rail, so that the barite that meets the size can be crushed. The barite falls on the opposite side of the hammering mechanism, prompting the hammer to hammer the outer side of the barite under the swinging action of the hinged connecting rod, prompting the barite to be initially broken, and then the barite falls on the opposite side of the material-discharging mechanism, and is pushed to both sides by the material-discharging mechanism, and the barite block slides on the opposite side of the material-discharging mechanism under the action of gravity, and the barite is crushed by the jaw crushing action of the active jaw crushing component and the fixed jaw crushing component, and finally guided out through the silicone soft frame and guided to the collection equipment through the diversion mechanism, so that the barite is perfectly crushed, and the overall structure has a good operating effect, which is convenient for sealing the equipment, and promotes the relatively uniform crushing of the barite, increases the stability of the jaw crusher, and indirectly improves the operating efficiency;

[0017] 2. When the servo motor drives the rotating shaft to rotate, the rotating shaft realizes counter-transmission through the meshing gear disc, so that the symmetrically distributed articulated seat, articulated rod and hammer strike the stone inward, thereby exerting the effect of preliminary striking and crushing and hammering distribution inward on the stone, which is convenient for the preliminary crushing of barite and reduces the uneven characteristics generated in the subsequent jaw crushing, thereby increasing the stability of the operation, increasing the uniformity of barite crushing, reducing blockage, and increasing the stability of the structure;

[0018] 3. When the servo motor 2 rotates, it drives the transmission shaft to rotate, thereby driving the reverse-moving auger disk to rotate. The two transmission shafts rotate synchronously, and the symmetrically distributed reverse-moving auger disks guide the stones inward and exert a force on both sides of the stones, so as to facilitate the uniform discharge of stones, reduce the blockage problem caused by uneven crushing, protect the operation of the equipment, and increase the relative stability of the structure;

[0019] 4. During the crushing process, smoke and dust will be generated on the inner side of the inner frame and the top frame. At this time, the vacuum pump is started, and negative pressure is formed inside the dust filter box through the discharge pipe. The airflow is guided through the connecting pipe 2, and through the connecting effect of the top ring pipe, the connecting pipe 1 and the bottom ring pipe, the airflow enters through the top guide pipe and the bottom guide pipe, and the airflow on the inner side of the top frame and the inner frame is guided out, so that the airflow carries the dust into the dust filter box, and is intercepted and filtered by the dust filter bag, and finally deposited at the conical bottom end of the dust filter bag, and enters the inside of the discharge pipe through the guidance of the guide hose. Finally, the operator unscrews the threaded sealing cover to collect the dust on the inside of the discharge pipe. Through the connection and guidance of the top ring pipe, the bottom ring pipe, the connecting pipe 1, the top guide pipe and the bottom guide pipe, the airflow and dust are evenly guided out, overflow is reduced, and the barite dust is conveniently collected and can be effectively recycled, which increases the convenience effect, avoids environmental pollution and waste, stabilizes the operation effect, and increases the environmental protection effect.

[0035] The working principle of the above technical solution is as follows: when in use, the operator puts the barite that has been initially broken after mining into the inner side of the inner frame 3 through the conveying device. When the equipment is started, the dual output shaft motor 901 rotates to drive the output shaft 902 to rotate, and drives the driven inertia transmission disk 601 through the active inertia transmission disk 903 and the transmission belt 602, thereby applying rotation to the eccentric drive shaft 605, and applying reciprocating motion to the active jaw crusher assembly 603 through the eccentric drive shaft 605, and then the servo motor 1 503 starts to drive the rotating shaft 501 to rotate, and drives the articulated seat 507, the articulated rod 506 and the striking hammer 505 to rotate, and then the barite is on the inner side of the inner frame 3, and at this time, the electric-controlled telescopic rod 2 301 is started to retract, prompting the two closed arc-shaped closing gates 302 to slide under the support of the arc-shaped guide bar 303 and produce A gap is created, so that the barite that meets the size falls on the opposite side of the hammering mechanism 5, prompting the hammer 505 to hammer the outside of the barite under the swinging action of the hinged connecting rod, prompting the barite to be initially broken, and then the barite falls on the opposite side of the material-discharging mechanism 10, and is pushed to both sides by the material-discharging mechanism 10, and under the action of gravity, the barite block slides on the opposite side of the material-discharging mechanism 10, and is crushed by the jaw crushing action of the active jaw crusher component 603 and the fixed jaw crusher component 604, and finally is guided out through the silicone soft frame 103 and guided to the collection equipment via the diversion mechanism 8, so that the barite is perfectly crushed, and the overall structure has a good operating effect, which is convenient for sealing the equipment, and prompts the barite to be crushed relatively evenly, thereby increasing the stability of the jaw crusher and indirectly improving the operating efficiency.

[0036] In another embodiment, Figure 1-Figure 9 As shown, one end of the electric telescopic rod 201 away from the guide plate 202 is hinged to the inner wall of the top frame 2, and the guide plate 202 is located on the opposite side of the hammering mechanism 5 and the material-dispensing mechanism 10. One end of the electric telescopic rod 301 away from the arc-shaped closing gate 302 is rotatably hinged to the inner wall of the top frame 2, and the specifications and dimensions of the arc-shaped guide rail 303 and the bottom of the inner frame 3 are compatible with the specifications and dimensions of the arc-shaped guide rail 303 and the bottom of the inner frame 3.

[0037] The extension and retraction of the electrically-controlled telescopic rod 201 can adjust the inclination angle of the guide plate 202, thereby directing the barite blocks broken at the hammering mechanism 5 to the opposite side of the material-displacing mechanism 10, thereby facilitating the displacing, and the extension and retraction of the electrically-controlled telescopic rod 301 can change the opening and closing position of the arc-shaped closing gate 302, thereby allowing the barite blocks of a size that meets the requirements of the operating equipment to enter, thereby avoiding mechanical overload and resulting in the accumulation of barite ore in the crushing chamber of the crusher, causing blockage and affecting the crushing efficiency, thereby increasing the protection effect of the equipment and indirectly increasing its service life.

[0038] In another embodiment, Figure 1-Figure 8 As shown, the material-dispensing mechanism 10 includes two transmission shafts 1001, and the outer sides of the two transmission shafts 1001 are fixedly installed with reverse-moving auger disks 1002. The two transmission shafts 1001 penetrate the machine casing 1 through bearings and extend to the outer side of the machine casing 1. One end of the two transmission shafts 1001 is transmission-connected with a sprocket chain transmission assembly 1003. The sprocket chain transmission assembly 1003 includes a sprocket and a chain. The sprocket is installed at the outer end of the transmission shaft 1001, and the chain is sleeved on the outer side of the sprocket. One end of the two transmission shafts 1001 is transmission-connected with a servo motor 2 1004, and the servo motor 2 1004 is fixedly installed on the outer side of the machine casing 1 through a bracket. There are four reverse-moving auger disks 1002, which are symmetrically and evenly distributed on the outer sides of the two transmission shafts 1001.

[0039] When the servo motor 1004 rotates, it drives the transmission shaft 1001 to rotate, thereby driving the reverse-moving auger disc 1002 to rotate. The two transmission shafts 1001 rotate synchronously, and the symmetrically distributed reverse-moving auger discs 1002 guide the stones inward and apply a force on both sides of the stones, thereby facilitating uniform discharge of the stones, reducing blockage problems caused by uneven crushing, protecting the operation of the equipment, and increasing the relative stability of the structure.

[0040] In another embodiment, Figure 1-Figure 8 As shown, the articulated seat 507 is spirally distributed evenly on the outside of the rotating shaft 501, the servo motor 503 is fixedly installed on the outside of the top frame 2 through a bracket, and one end of the striking hammer 505 is conical and the other end is spherical.

[0041] When the servo motor 503 drives the rotating shaft 501 to rotate, the rotating shaft 501 realizes counter-transmission through the meshing gear plate 504, so that the symmetrically distributed articulated seat 507, the articulated rod 506 and the striking hammer 505 strike the stone inward, thereby applying the effect of preliminary striking and crushing and inward hammering distribution to the stone, which is convenient for the preliminary crushing of the barite and reduces the uneven characteristics generated in the subsequent jaw crushing, thereby increasing the stability of the operation, increasing the uniformity of the barite crushing, reducing the blockage and increasing the stability of the structure.

[0042] In another embodiment, Figure 1-Figure 10 As shown, the active jaw crusher assembly 603 is evenly and movably connected to the inner wall of the casing 1 through a plurality of elastic telescopic columns and elastic assemblies, and a plurality of arc-shaped jaw racks 606 and rectangular jaw racks 607 are fixedly installed on the opposite sides of the active jaw crusher assembly 603 and the fixed jaw crusher assembly 604. The arc-shaped jaw racks 606 and the rectangular jaw racks 607 are linearly staggered and evenly distributed on the opposite sides of the active jaw crusher assembly 603 and the fixed jaw crusher assembly 604.

[0043] The active jaw crusher assembly 603 maintains a relatively stable position under the limitation of the elastic telescopic column and the elastic member, and is suspended through the bearing movement of the eccentric drive shaft 605, thereby driving the active jaw crusher assembly 603 to swing and combine with the fixed jaw crusher assembly 604 to extrude and crush the barite. The uniform arrangement of the arc-shaped jaw rack 606 and the rectangular jaw rack 607 is convenient for increasing the crushing uniformity of the barite. The arc-shaped jaw rack 606 increases the extrusion strength, and the rectangular jaw rack 607 enhances the force of the extrusion section, thereby cooperating with each other to increase the uniformity of the jaw crushing, thereby stabilizing the crushing effect.

[0044] In another embodiment, Figure 1-Figure 6 As shown, the fixing frame 904 is fixedly mounted on the outer wall of the housing 1 , the bearing bracket 906 is fixedly mounted on the outer wall of the housing 1 , and the outer side of the active inertia transmission disc 903 is sleeved with the inner side of the transmission belt 602 for transmission.
