Description

Technical Field

[0001] The invention relates to the technical field of mixing devices, and in particular to a bulk material processing, dosing and mixing device and process. Background Art

[0002] In the field of bulk material processing, the dosing and mixing device plays a key role in ensuring product quality and improving production efficiency. The currently used bulk material processing dosing and mixing device has basic mixing functions, but when the amount of material is small, it is difficult for the stirring blades to fully contact and stir all the materials, causing some materials to be in a relatively static state and unable to achieve uniform mixing. In addition, when the amount of material exceeds the rated value, the material will hinder the normal operation of the stirring blades, weaken the transmission of stirring power, and greatly reduce the stirring strength and uniformity. Secondly, during the stirring process, affected by factors such as the material's own viscosity, humidity, and electrostatic effects, the material is easy to adhere to the inner wall of the mixing drum. As time goes by, the material adhered to the inner wall continues to accumulate, which not only reduces the amount of material actually involved in the mixing and destroys the accuracy of the dosing, but also these materials adhered to the inner wall of the mixing drum cannot be fully contacted and stirred with other materials, which seriously reduces the overall mixing effect.

[0008] Furthermore, the adjustment assembly also includes a plurality of push rods, each of which is extended in the radial direction of the mixing barrel, each of which is telescopic, and each of which is arranged between the inner wall of the mixing barrel and one of the support rods.

[0009] Furthermore, it also includes a driving assembly, which is used to drive the stirring sleeve to rotate around the axis of the mixing barrel.

[0010] Furthermore, the driving assembly includes a driving roller, a friction sleeve and a driving motor; the driving roller is rotatably arranged outside the stirring sleeve, the driving roller abuts against the outer wall of the stirring sleeve, and the driving roller and the positioning roller are in the radial direction of the mixing drum; the friction sleeve is arranged on the outer wall of the driving roller, and the driving motor is used to drive the driving roller to rotate.

[0011] Furthermore, a fixed disk is provided at the end of the stirring shaft, and a plurality of first hinge grooves are provided on the fixed disk, and each end of the stirring plate is hinged in one of the first hinge grooves.

[0012] Furthermore, an adjustment disk is slidably arranged on the stirring shaft, and a plurality of second hinge grooves are arranged on the adjustment disk. A hinge rod is hinged in each of the second hinge grooves, and the other end of each hinge rod is hinged to the middle of one of the stirring plates.

[0013] Furthermore, a limit spring is arranged on the stirring shaft, the limit spring is arranged between the fixed disk and the adjusting disk, and the limit spring is used to limit the distance between the fixed disk and the adjusting disk to be less than a first preset value.

[0014] Furthermore, the mixing cylinder is provided with an active motor, and the active motor is used to drive the stirring shaft to rotate.

[0015] A bulk material processing, dosing and mixing process, using the above-mentioned bulk material processing, dosing and mixing device, comprises the following steps:

[0016] S1, conveying materials into the mixing chamber through the feed inlet;

[0017] S2, using the stirring shaft to drive the plurality of stirring plates to stir the material in the mixing chamber;

[0018] S3, when the stirring plate stirs the material in the mixing chamber, adjusting the ratio of the mixing chamber to the dust removal chamber.

[0020] Furthermore, when the stirring plate stirs and mixes the materials in the mixing chamber, the stirring sleeve rotates around the axis of the mixing barrel. During the rotation of the stirring sleeve, if the material adheres to the inner wall of the stirring sleeve, when the impurities attached to the inner wall of the stirring sleeve enter the dust removal chamber from the mixing chamber, the bending form of the stirring sleeve changes, and the material attached to the inner wall of the stirring sleeve can actively separate from the stirring sleeve, thereby avoiding the material ratio being affected by the material adhered to the inner wall of the stirring sleeve.

Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.

[0031] like Figures 1 to 5 As shown, an embodiment of the present invention provides a bulk material processing and dosing mixing device, which includes a mixing barrel 110, a stirring sleeve 120, a stirring shaft 130 and an adjusting component.

[0032] The mixing barrel 110 is slightly cylindrical and is vertically arranged. A bracket 111 is arranged on the mixing barrel 110, and the bracket 111 can maintain the mixing barrel 110 in a stable vertical state. The interior of the mixing barrel 110 is hollow. A feed port 112 connecting the interior of the mixing barrel 110 with the external environment is arranged at the upper end of the mixing barrel 110, and a discharge port 113 connecting the interior of the mixing barrel 110 with the external environment is arranged at the lower end of the mixing barrel 110. Furthermore, a first sealing plate and a second sealing plate are arranged on the mixing barrel 110, and the first sealing plate and the second sealing plate are both detachably connected to the mixing barrel 110. The first sealing plate can block the feed port 112, and the second sealing plate can block the discharge port 113. When it is necessary to transport materials into the mixing barrel 110, the first sealing plate is removed from the mixing barrel 110, and when it is necessary to discharge materials from the mixing barrel 110, the second sealing plate is removed from the mixing barrel 110.

[0033] The stirring sleeve 120 is annular and is vertically arranged inside the mixing barrel 110. The stirring sleeve 120 has an inner wall close to the axis of the mixing barrel 110 and an outer wall away from the axis of the mixing barrel 110. There is a gap between the outer wall of the stirring sleeve 120 and the inner wall of the mixing barrel 110. The lower end of the stirring sleeve 120 is always in contact with the lower end surface of the inner wall of the mixing barrel 110. The inner wall of the stirring sleeve 120 and the lower end surface of the inner wall of the mixing barrel 110 can form a relatively independent chamber. Since the stirring sleeve 120 is a cylindrical structure that penetrates from top to bottom, the material entering the mixing barrel 110 through the feed port 112 can directly enter the stirring sleeve 120. Furthermore, the stirring sleeve 120 can be deformed, and the stirring sleeve 120 forms a mixing chamber 121 and a dust removal chamber 122 that are interconnected inside the mixing barrel 110. Since the total circumference of the stirring sleeve 120 remains constant, the volume of the stirring sleeve 120 is at its maximum when it is in a cylindrical state. After the stirring sleeve 120 forms the mixing chamber 121 and the dust removal chamber 122, the total volume inside the stirring sleeve 120 will decrease.

[0034] The stirring shaft 130 is coaxially connected to the mixing drum 110, and the lower end of the stirring shaft 130 extends to the inside of the mixing drum 110. The upper end of the stirring shaft 130 is arranged outside the mixing drum 110, and the lower end of the stirring shaft 130 is in the mixing chamber 121. A plurality of stirring plates 140 are arranged at the lower end of the stirring shaft 130, and the ends of the plurality of stirring plates 140 can abut against the inner side wall of the stirring sleeve 120 corresponding to the mixing chamber 121. There is an angle between the stirring plates 140 and the stirring shaft 130. When the stirring shaft 130 rotates, the stirring shaft 130 drives the plurality of stirring plates 140 to move synchronously. During the movement of the stirring plates 140, the stirring plates 140 stir the materials in the mixing chamber 121. Since there is an angle between the stirring plates 140 and the stirring shaft 130, the materials can be fully mixed in the vertical direction of the mixing chamber 121.

[0035] The adjustment component is used to adjust the ratio of the mixing chamber 121 and the dust removal chamber 122. Specifically, after the adjustment component adjusts the ratio of the mixing chamber 121 and the dust removal chamber 122, the height of the material in the mixing chamber 121 will change. When the amount of material entering the mixing chamber 121 is small, the volume of the mixing chamber 121 is reduced and the volume of the dust removal chamber 122 is increased. At this time, the total volume inside the stirring sleeve 120 decreases, and the height of the material in the mixing chamber 121 is increased, thereby ensuring that the stirring shaft 130 can fully stir the material.

[0036] The present invention provides a bulk material processing and dosing mixing device. When dosing and mixing bulk materials, the bulk materials are transported to the inside of the mixing drum 110 through the feed port 112 according to the preset dosing amount. The position of the stirring sleeve 120 is set so that the materials entering the mixing drum 110 enter the mixing chamber 121. Then, the stirring shaft 130 is started to rotate on the mixing drum 110. The rotating stirring shaft 130 drives multiple stirring plates 140 to mix and stir the materials at the same time. Since there is an angle between the stirring plate 140 and the stirring shaft 130, the materials will be mixed in the vertical direction during the stirring of the materials by the stirring plate 140. In a step, the stirring sleeve 120 is surrounded by a mixing chamber 121 and a dust removal chamber 122, and the adjusting component can adjust the ratio of the mixing chamber 121 and the dust removal chamber 122. When the volume of the mixing chamber 121 increases, the volume of the dust removal chamber 122 decreases. On the contrary, when the volume of the dust removal chamber 122 increases, the volume of the mixing chamber 121 decreases. When the amount of material entering the mixing chamber 121 is small, the adjusting component adjusts the ratio of the mixing chamber 121 and the dust removal chamber 122, and the total volume inside the stirring sleeve 120 is reduced, and the material height in the mixing chamber 121 is changed, thereby achieving sufficient mixing of the material.

[0037] In one embodiment, the adjustment assembly includes a positioning roller 210 and a plurality of support rods 220, the support rods 220 are vertically arranged, the extension direction of the support rods 220 is parallel to the axial direction of the mixing drum 110, the support rods 220 always abut against the outer wall of the stirring sleeve 120, the plurality of support rods 220 are evenly distributed around the circumference of the mixing drum 110, each support rod 220 can slide in the radial direction of the mixing drum 110, and the plurality of support rods 220 simultaneously move in the radial direction of the mixing drum 110. The positioning roller 210 is arranged between any two support rods 220, the positioning roller 210 is arranged parallel to the support rods 220, the length of the positioning roller 210 is equal to the length of the support rods 220, and the length of the positioning roller 210 is equal to the height of the stirring sleeve 120 in the vertical direction. The positioning roller 210 always abuts against the inner side wall of the stirring sleeve 120. In the initial state, the distance between the positioning roller 210 and the axis of the mixing barrel 110 is greater than the distance between the support rod 220 and the axis of the mixing barrel 110, and the stirring sleeve 120 forms two interconnected mixing chambers 121 and dust removal chambers 122. Further, when the plurality of support rods 220 slide along the radial direction of the mixing barrel 110, the ratio between the mixing chamber 121 and the dust removal chamber 122 can change.

[0038] In one embodiment, the adjustment assembly further includes a plurality of push rods 230, each push rod 230 is arranged corresponding to a support rod 220, the axial direction of each push rod 230 is extended along the radial direction of the mixing barrel 110, each push rod 230 can be telescopically arranged, one end of the push rod 230 is fixedly connected to the inner wall of the mixing barrel 110, and the other end of the push rod 230 is fixedly connected to the support rod 220. When the length of the push rod 230 changes, the distance between the support rod 220 and the axial direction of the mixing barrel 110 changes, thereby causing the ratio between the mixing chamber 121 and the dust removal chamber 122 to change. For example, the push rod 230 is an electrically controlled telescopic rod, and the length changes of multiple push rods 230 can be performed synchronously. Furthermore, the push rod 230 is in a state of reciprocating extension and contraction. When the material in the mixing chamber 121 is stirred, the ratio of the mixing chamber 121 to the dust removal chamber 122 is in a gradual state, and the height of the material in the mixing chamber 121 is in a constantly changing state, thereby further improving the uniformity of material mixing.

[0039] In one of the embodiments, a bulk material processing and dosing mixing device also includes a driving component, which is used to drive the stirring sleeve 120 to rotate around the axis of the mixing barrel 110. If there is material attached to the inner wall of the stirring sleeve 120, during the rotation of the stirring sleeve 120, the material attached to the inner wall of the stirring sleeve 120 will enter the dust removal chamber 122. During this process, the bending form of the stirring sleeve 120 changes, and the material attached to the inner wall of the stirring sleeve 120 can actively detach from the stirring sleeve 120, thereby reducing the probability of the material adhering to the inner wall of the stirring sleeve 120 and affecting the material ratio.

[0040] In one embodiment, the driving assembly includes a driving roller 240, a friction sleeve and a driving motor; the driving roller 240 is vertically arranged, the driving roller 240 is rotatably connected to the mixing drum 110, the driving roller 240 and the support rod 220 are spaced apart, the driving roller 240 is arranged between the outer wall of the stirring sleeve 120 and the inner wall of the mixing drum 110, the length of the driving roller 240 is equal to the length of the support rod 220, the gap between the driving roller 240 and the support rod 220 is equal to the thickness of the stirring sleeve 120, and the driving roller 240 abuts against the outer wall of the stirring sleeve 120. The friction sleeve is fixedly arranged on the driving roller 240, and the friction sleeve can be deformed. For example, the friction sleeve is made of rubber. When the driving roller 240 rotates, the stirring sleeve 120 rotates inside the mixing drum 110 through the transmission of the friction sleeve. The driving motor is fixedly connected to the mixing drum 110, and the power output shaft of the driving motor is coaxially fixedly connected to the driving roller 240, so that the driving motor can drive the driving roller 240 to rotate. Furthermore, the driving motor is used to start when the stirring shaft 130 stirs the material.

[0041] Furthermore, a positioning plate 250 is fixedly provided inside the mixing barrel 110. The positioning plate 250 is coaxially arranged with the mixing barrel 110, and the lower end surface of the positioning plate 250 abuts against the upper end of the stirring sleeve 120. By setting the positioning plate 250, it is ensured that the stirring sleeve 120 does not jump in the vertical direction when rotating. At the same time, by setting the positioning plate 250, it is ensured that the gap between the lower end of the stirring sleeve 120 and the inner wall of the mixing barrel 110 is stable, thereby reducing the material from escaping from the stirring chamber or the dust removal chamber 122 through the gap between the lower end of the stirring sleeve 120 and the inner wall of the mixing barrel 110.

[0042] In one of the embodiments, a fixed disk 260 is fixedly provided at the lower end of the stirring shaft 130, and the fixed disk 260 is in a coaxial state with the stirring shaft 130. A plurality of first hinge grooves 261 are provided on the fixed disk 260, and the plurality of first hinge grooves 261 are evenly distributed around the circumferential direction of the fixed disk 260. The number of the plurality of first hinge grooves 261 is the same as the number of the plurality of stirring plates 140, and one end of each stirring plate 140 is hinged in a first hinge groove 261. In the initial state, the end of the stirring plate 140 close to the stirring shaft 130 is below the end away from the stirring shaft 130, and the end of the stirring plate 140 away from the stirring shaft 130 is in a state of abutting the inner wall of the stirring sleeve 120. As the volume of the mixing chamber 121 decreases, the angle between the stirring shaft 130 and the stirring plate 140 gradually decreases.

[0043] In one embodiment, an adjusting disk 270 is coaxially arranged on the stirring shaft 130, and the adjusting disk 270 can slide on the stirring shaft 130. The adjusting disk 270 is arranged above the fixed disk 260, and a plurality of second hinge grooves 271 are arranged on the adjusting disk 270. The plurality of second hinge grooves 271 are evenly distributed around the circumferential direction of the adjusting disk 270, and the number of the plurality of second hinge grooves 271 is the same as the number of the plurality of first hinge grooves 261. A hinge rod 280 is hinged in each second hinge groove 271, and the end of each hinge rod 280 is hinged to the middle of the stirring plate 140. When the angle between the stirring plate 140 and the stirring shaft 130 changes, the adjusting disk 270 slides on the stirring shaft 130 through the transmission of the hinged rod 280, wherein the distance between the adjusting disk 270 and the fixed disk 260 cannot be less than a first preset value, and the first preset value is a parameter that is considered to be set. When the distance between the adjusting disk 270 and the fixed disk 260 is greater than or equal to the first preset value, it is ensured that the angle between the stirring plate 140 and the stirring shaft 130 is less than ninety degrees, thereby ensuring that the stirring plate 140 will not flip downward when the ratio of the mixing chamber 121 to the dust removal chamber 122 changes.

[0044] In one embodiment, a limit spring 310 is provided on the stirring shaft 130, and the limit spring 310 is sleeved on the outside of the stirring shaft 130. The limit spring 310 is provided between the fixed disk 260 and the adjusting disk 270. The limit spring 310 and the fixed disk 260 or the adjusting disk 270 are all in a disconnected state. The limit spring 310 abuts against the fixed disk 260 under the action of its own gravity. When the limit spring 310 is in the original length state and the adjusting disk 270 and the fixed disk 260 abut against the limit spring 310 at the same time, the distance between the adjusting disk 270 and the fixed disk 260 is greater than the first preset value.

[0045] In one embodiment, a driving motor 320 is disposed on the mixing drum 110 , and a power output shaft of the driving motor 320 is coaxially fixedly connected with the stirring shaft 130 . When the driving motor 320 is started, the stirring shaft 130 is driven to rotate.

[0046] A bulk material processing, dosing and mixing process, using a bulk material processing, dosing and mixing device, specifically includes the following steps:

[0047] S1, conveying materials into the mixing chamber 121 through the feed port 112, wherein the materials conveyed into the mixing chamber 121 have a certain ratio, and after the materials completely enter the mixing chamber 121, the feed port 112 is blocked to prevent the materials from escaping from the mixing chamber 121 through the feed port 112.

[0048] S2, using the stirring shaft 130 to drive the plurality of stirring plates 140 to stir the materials in the mixing chamber 121, and when the plurality of stirring plates 140 stir the materials, the materials can be mixed.

[0049] S3, when the stirring plate 140 stirs the material in the mixing chamber 121, the proportion of the mixing chamber 121 and the dust removal chamber 122 is adjusted. Specifically, when the amount of material entering the mixing chamber 121 is small, the volume of the mixing chamber 121 is reduced and the volume of the dust removal chamber 122 is increased. At this time, the total volume inside the stirring sleeve 120 decreases, and the height of the material in the mixing chamber 121 increases, thereby ensuring that the stirring shaft 130 can fully stir the material.
