Description

Technical Field

[0001] The invention relates to the technical field of granulation equipment, in particular to granulation equipment for producing xanthate products. Background Art

[0002] Xanthate is a collector commonly used in sulfide ore flotation. It is an indispensable agent in sulfide ore beneficiation due to its low price, strong collecting capacity and convenient use. The production process of xanthate includes powder alkali preparation, freezing reaction, synthesis reaction, extrusion molding, drying and packaging.

[0003] First, the powder alkali preparation process in the production process is to grind the flake sodium hydroxide into powder for use in the synthesis reaction. Then, the freezing process reduces the reaction temperature through the refrigeration system to ensure that the synthesis reaction can be carried out at a lower temperature to avoid the reaction too fast and cause poor product quality. The synthesis process is a key link. Xanthate is generated by the reaction of alcohols, carbon disulfide and sodium hydroxide. This reaction needs to be completed under closed and low temperature conditions. The synthesized xanthate material enters the extrusion process and is formed into a strip material by spiral extrusion. To prevent the decomposition of the agent, the material temperature needs to be cooled. After that, the strip material is further granulated by vacuum drying technology through the drying process to ensure that the product quality meets the export requirements. However, in actual granulation production, the existing granulation equipment has the problem of easy clogging. Frequent cleaning of the equipment increases the production cost and the labor burden of the workers, resulting in reduced efficiency in the production of xanthate. Summary of the invention

[0032] like Figures 1 to 9 As shown, an embodiment of the present invention provides a granulating device for producing a xanthate product, which includes a bracket 110, a conveying cylinder 120, a mounting sleeve 140 and a cutting knife.

[0033] The bracket 110 is fixedly arranged on the ground, and the bracket 110 has a mounting platform, and the mounting platform is arranged horizontally.

[0034] The conveying cylinder 120 is fixedly arranged on the bracket 110, and the axis of the conveying cylinder 120 is arranged horizontally. The conveying cylinder 120 is fixedly arranged on the mounting platform. The conveying cylinder 120 has a conveying channel inside, and the conveying channel passes through the two end surfaces in the axial direction. The conveying cylinder 120 has a first end and a second end in the axial direction. The first end of the conveying cylinder 120 is provided with a feeding port connecting the external environment with the conveying channel, and the second end of the conveying cylinder 120 is provided with a discharge port connecting the external environment with the conveying channel. Specifically, in order to facilitate the supply of materials into the conveying channel, a feeding funnel 130 is arranged at the position of the feeding port. The feeding funnel 130 can reduce the probability of materials being spilled into the external environment during the process of feeding materials into the conveying channel. A conveying member is provided in the conveying channel, and the conveying member is used to convey the material entering the conveying channel from the feed port to the discharge port. For example, the conveying member is a conveying auger 160, and the conveying auger 160 is coaxially arranged inside the conveying channel. A driving motor 170 is provided on the bracket 110, and the driving motor 170 is used to drive the conveying auger 160 to rotate in the conveying channel. The conveying auger 160 can convey the material entering the conveying channel from the feed port to the discharge port.

[0035] The mounting sleeve 140 is coaxially mounted on the second end of the conveying cylinder 120. The inner diameter of the mounting sleeve 140 is equal to the inner diameter of the conveying cylinder 120. The mounting sleeve 140 is provided with a granulating disc 150. In the initial state, the granulating disc 150 is coaxially arranged with the mounting sleeve 140. The outer diameter of the granulating disc 150 is smaller than the inner diameter of the mounting sleeve 140, so as to ensure that the granulating disc 150 can rotate inside the mounting sleeve 140. When the granulating disc 150 is coaxial with the conveying cylinder 120, the granulating disc 150 has a first side wall close to the conveying cylinder 120 and a second side wall away from the conveying cylinder 120. The granulating disc 150 is rotatably connected to the mounting sleeve 140. Furthermore, the rotating shaft between the granulating disc 150 and the mounting sleeve 140 is vertically arranged. When the granulating disc 150 rotates, the positions of the first side wall and the second side wall on the granulating disc 150 are interchanged, that is, the granulating disc 150 is flipped 180 degrees. The granulation disk 150 is provided with a plurality of mounting grooves penetrating the first side wall and the second side wall, and the plurality of mounting grooves are evenly distributed around the circumference of the granulation disk 150. An extrusion head 220 is provided in each mounting groove, and an extrusion channel 221 is provided in the extrusion head 220. When the conveying member conveys the material to the discharge port, the material accumulates at the discharge port, and when the material passes through the extrusion channel 221 on the extrusion head 220, the material is extruded into a strip structure.

[0036] The cutting knife is used to cut the material discharged from the extrusion channel 221. Under the action of the cutting knife, the material can be cut into granules. When the extrusion channel 221 is blocked, the conveying member stops conveying the material. At this time, the granulation disk 150 is driven to rotate on the mounting sleeve 140. After the granulation disk 150 rotates, the positions of the first side wall and the second side wall of the granulation disk 150 are interchanged. At this time, the conveying member is started again to convey the material. When the material passes through the extrusion channel 221, the material blocking the extrusion channel 221 can be cleaned out, reducing manual intervention, thereby improving the granulation efficiency of the material.

[0037] The present invention provides a granulating device for producing xanthate products. When granulating xanthate, the material for preparing the xanthate is put into the conveying channel through the feed port of the conveying cylinder 120. Under the action of the conveying member, the material moves from the feed port to the discharge port. Under the action of the conveying member, the material can be accumulated at the discharge port. By arranging a granulating disk 150 at the discharge port and installing a plurality of extrusion heads 220 on the granulating disk 150, the material is extruded into a strip structure when passing through the extrusion channel 221 on the extrusion head 220. The material discharged from the extrusion channel 221 is cut by the action of the cutting knife, so that the material is formed into granules. When the extrusion channel 221 is blocked, the conveying member stops conveying the material. At this time, the granulating disk 150 is driven to rotate on the mounting sleeve 140. After the granulating disk 150 rotates, the positions of the first side wall and the second side wall of the granulating disk 150 are interchanged. At this time, the conveying member is started again to convey the material. When the material passes through the extrusion channel 221, the material blocking the extrusion channel 221 can be cleaned out, reducing manual intervention, thereby improving the granulation efficiency of the material, and further improving the efficiency of producing xanthate.

[0038] In one embodiment, the conveying member includes a conveying auger 160, which is coaxially arranged with the conveying cylinder 120. Specifically, the conveying auger 160 includes a driving shaft 161 and an auger blade 162. The driving shaft 161 is coaxially arranged with the conveying cylinder 120. The auger blade 162 is fixedly connected to the driving shaft 161, and the auger blade 162 is always in contact with the inner wall of the conveying cylinder 120. The conveying auger 160 is a variable pitch auger. The pitch of the conveying auger 160 gradually decreases from the first end of the conveying cylinder 120 to the second end of the conveying cylinder 120. Specifically, the pitch of the auger blade 162 is in a gradual state. The pitch of the auger blade 162 gradually decreases from the first end of the conveying cylinder 120 to the second end of the conveying cylinder 120. When the conveying auger 160 rotates, the auger blade 162 of the conveying auger 160 can squeeze the material. A driving source is provided on the bracket 110, and the driving source is used to drive the conveying auger 160 to rotate in the conveying channel. Specifically, the driving source includes a driving motor 170 and a gearbox. The driving motor 170 is fixedly arranged on the bracket 110, and the gearbox is fixedly arranged on the bracket 110. The gearbox has a power input end and a power output end. The power output shaft of the driving motor 170 is connected to the power input end of the gearbox, and the driving shaft 161 of the conveying auger 160 is connected to the power output end of the gearbox. Under the action of the gearbox, the driving shaft 161 has sufficient torque to transport the material.

[0039] In one embodiment, a connecting ball 210 is provided at the second end of the conveying auger 160 near the conveying cylinder 120, and specifically, the connecting ball 210 is provided at the end of the driving shaft 161. A ball connection groove is provided in the middle of the granulating disc 150, and the connecting ball 210 is provided in the ball connection groove. Under the action of the connecting ball 210 and the ball connection groove, the granulating disc 150 can rotate at the end of the driving shaft 161. A limiting sleeve 180 is provided between the granulating disc 150 and the mounting sleeve 140, and the inner diameter of the limiting sleeve 180 is equal to the outer diameter of the granulating disc 150, and the outer diameter of the limiting sleeve 180 is equal to the inner diameter of the mounting sleeve 140. By providing the limiting sleeve 180, the material is prevented from leaving the conveying channel through the gap between the granulating disc 150 and the mounting sleeve 140. The limiting sleeve 180 is rotatably connected with the mounting sleeve 140, and the limiting sleeve 180 is vertically arranged on the rotating shaft of the mounting sleeve 140. When the limiting sleeve 180 rotates, the limiting sleeve 180 drives the granulating disk 150 to rotate synchronously, and the positions of the first side wall and the second side wall of the granulating disk 150 are interchanged. The inner side wall of the limiting sleeve 180 is set to an arc shape, and the outer side wall of the granulating disk 150 is set to an arc shape. The outer side wall of the granulating disk 150 abuts against the inner side wall of the limiting sleeve 180, and the granulating disk 150 is rotatably arranged in the limiting sleeve 180. In a further setting, the arc center of the arc of the outer side wall of the granulating disk 150 is located at the axis of the granulating disk 150, and the arc center of the arc of the inner side wall of the limiting sleeve 180 is located at the axis of the granulating disk 150. It is easy to understand that the granulating disk 150 is a plate-like structure intercepted on a ball, and the granulating disk 150 can rotate around any direction in the limiting sleeve 180. The extension direction of the extrusion channel 221 in the extrusion head 220 has a preset angle with the axial direction of the mounting sleeve 140. Specifically, the outer contour of the extrusion head 220 is slightly cylindrical. When the axis of the granulation disk 150 is coaxial with the limiting sleeve 180, the extension direction of the extrusion channel 221 in the extrusion head 220 has a preset angle with the axial direction of the mounting sleeve 140, and the preset angle is constant. When the granulation disk 150 rotates in the limiting sleeve 180, the size of the preset angle between the extension direction of the extrusion channel 221 in the extrusion head 220 and the axial direction of the mounting sleeve 140 changes.Furthermore, when the extrusion channels 221 in the multiple extrusion heads 220 on the granulation disk 150 are not blocked, the extrusion force of the conveying auger 160 on the material can act evenly on the first side wall of the granulation disk 150. If the extrusion channels 221 in the extrusion heads 220 in a local area of ​​the granulation disk 150 are blocked by materials, the extrusion force of the conveying auger 160 on the material cannot act evenly on the first side wall of the granulation disk 150. At this time, the first side wall of the granulation disk 150 is subjected to uneven force, causing the granulation disk 150 to deflect in the limiting sleeve 180. At this time, the preset angle between the blocked part of the extrusion channel 221 and the axial direction of the mounting sleeve 140 is reduced, and the preset angle between the unblocked part of the extrusion channel 221 and the axial direction of the mounting sleeve 140 is increased. After the preset angle between the blocked part of the extrusion channel 221 and the axial direction of the mounting sleeve 140 is reduced, the material blocking the extrusion channel 221 can be easily discharged, thereby realizing the cleaning of the material blocking the extrusion channel 221. If the granulation disk 150 rotates relative to the mounting sleeve 140 and the material blocking the extrusion channel 221 still cannot be cleaned, the driving limit sleeve 180 is rotated one hundred and eighty degrees on the mounting sleeve 140. At this time, the first side wall and the second side wall of the granulation disk 150 are interchanged. During the interchange of the first side wall and the second side wall of the granulation disk 150, the connecting ball 210 can be detached from the end of the driving shaft 161 to prevent the connecting ball 210 from obstructing the interchange of the first side wall and the second side wall of the granulation disk 150.

[0040] In one embodiment, a switching member is provided on the granulation disk 150, and the extrusion head 220 can rotate in the installation groove. The switching member is used to drive the extrusion head 220 to rotate a fixed angle in the installation groove after the limit sleeve 180 rotates. Specifically, the extension direction of the extrusion channel 221 in the extrusion head 220 and the axial direction of the installation sleeve 140 have a preset angle. After the limit sleeve 180 rotates, the first side wall and the second side wall of the granulation disk 150 are interchanged, and the angle between the extension direction of the extrusion channel 221 in the extrusion head 220 and the axial direction of the installation sleeve 140 changes. At this time, the switching member drives the extrusion head 220 to rotate a fixed angle in the installation groove to ensure that the extension direction of the extrusion channel 221 in the extrusion head 220 at the same position does not change.

[0041] In one embodiment, the switching member includes a switching knob 230 and a transmission sleeve 240. The switching knob 230 is rotatably connected to the granulation disk 150. The granulation disk 150 has a regulating cavity inside. The switching knob 230 extends into the regulating cavity. The axial direction of the switching knob 230 is parallel to the axial direction of the granulation disk 150. One end of the switching knob 230 is arranged on the outer side of the second side wall of the granulation disk 150, and the other end of the switching knob 230 is arranged on the outer side of the first side wall of the granulation disk 150. The transmission sleeve 240 is rotatably arranged in the regulating cavity, the transmission sleeve 240 is coaxially arranged with the granulation disk 150, the inner and outer walls of the transmission sleeve 240 are both provided with teeth, the outer wall of the switching knob 230 is provided with teeth, and the switching knob 230 is always engaged with the inner wall of the transmission sleeve 240; the outer wall of each extrusion head 220 is provided with teeth, and the outer wall of the transmission sleeve 240 is engaged with multiple extrusion heads 220 at the same time. After the limit sleeve 180 rotates, the switching knob 230 is driven to rotate a certain angle, and the switching knob 230 drives the transmission sleeve 240 to rotate. After the transmission of the transmission sleeve 240, each extrusion head 220 rotates in an installation groove. After the limit sleeve 180 rotates, the first side wall and the second side wall of the granulation disk 150 are interchanged. By rotating the switching knob 230, the angle between the extension direction of the extrusion channel 221 in the extrusion head 220 and the axial direction of the installation sleeve 140 can be restored to the initial state.

[0042] In one embodiment, a reset member is provided on the limiting sleeve 180, and the reset member is used to drive the granulating disc 150 to restore the coaxial state of the limiting sleeve 180 after the granulating disc 150 rotates relative to the limiting sleeve 180. Specifically, when the granulating disc 150 rotates in the limiting sleeve 180, the predetermined angle between the extension direction of the extrusion channel 221 in the extrusion head 220 and the axial direction of the mounting sleeve 140 changes. Furthermore, when the extrusion channels 221 in the multiple extrusion heads 220 on the granulation disk 150 are not blocked, the extrusion force of the conveying auger 160 on the material can be uniformly applied to the first side wall of the granulation disk 150. If the extrusion channels 221 in the extrusion heads 220 in a local area of ​​the granulation disk 150 are blocked by the material, the extrusion force of the conveying auger 160 on the material cannot be uniformly applied to the first side wall of the granulation disk 150. At this time, the first side wall of the granulation disk 150 is subjected to uneven force, causing the granulation disk 150 to deflect in the limiting sleeve 180. At this time, the blocked part of the extrusion channels 221 and the installation sleeve 180 are not uniformly applied to the first side wall of the granulation disk 150. 40, the preset angle in the axial direction is reduced, and the preset angle between the unblocked part of the extrusion channel 221 and the axial direction of the mounting sleeve 140 is increased. After the preset angle between the blocked part of the extrusion channel 221 and the axial direction of the mounting sleeve 140 is reduced, the material blocking the extrusion channel 221 can be easily discharged, thereby realizing the cleaning of the material blocking the extrusion channel 221. When the granulation disk 150 is deflected relative to the limiting sleeve 180, the reset part starts to accumulate force. When the material blocking the extrusion channel 221 is discharged from the extrusion channel 221, the reset part starts to release force, and the reset part drives the granulation disk 150 to return to its initial state.

[0043] In one embodiment, the reset member includes two elastic rings 250, which are coaxially arranged on the inner wall of the limiting sleeve 180, and the two elastic rings 250 are spaced apart along the axial direction of the limiting sleeve 180; one of the elastic rings 250 contacts the first side wall of the granulation disk 150, and the other elastic ring 250 contacts the second side wall of the granulation disk 150. When the granulation disk 150 deflects relative to the limiting sleeve 180, the granulation disk 150 can squeeze the elastic ring 250. After being squeezed, the elastic ring 250 can deform. The deformation of the elastic ring 250 can store force. During the force release process, the elastic ring 250 can drive the granulation disk 150 to return to its initial state.

[0044] In one embodiment, the limiting sleeve 180 is provided with a first rotating shaft 260, the first rotating shaft 260 is rotatably connected to the mounting sleeve 140, the first rotating shaft 260 is vertically arranged, and the first rotating shaft 260 is fixedly connected to the limiting sleeve 180. The conveying cylinder 120 is provided with a switching rod 270, one end of which is connected to the mounting sleeve 140, and the switching rod 270 can separate the mounting sleeve 140 from the second end of the conveying cylinder 120.
