Description

Technical Field

[0001] The invention belongs to the technical field of raw material mixing equipment, in particular to an integrated equipment for mixing raw materials for ceramsite sintering. Background Art

[0002] In the prior art of utilizing waste materials to make expanded clay and expanded clay powder, the main raw materials include oil sludge and oily garbage, secondary aluminum ash, solid waste of contaminated soil, etc., and the oil sludge is decomposed into dry mud for standby use. It is difficult to mix the fly ash and bottom ash after the incineration of the oily garbage with the dry mud. In the process of mixing the bottom ash and the dry mud, there is a problem of agglomeration of the dry mud and agglomeration of the bottom ash of the oily garbage. Therefore, the mixing process needs to be fully stirred and the agglomeration needs to be eliminated at the same time.

[0003] In addition, the traditional stirring equipment in the raw material mixing process is generally a tank-type equipment. After the raw materials are input into the sealed tank, the stirring rod is driven by a motor for stirring. There are some problems with this stirring device. Since the stirring length and layout of the stirring rod cannot fully cover the entire position of the sealed tank, stirring requires a relatively long time. In addition, since the dry mud agglomerates have a hard core, it is difficult to completely break it even if it is fully stirred. The hard core needs to be separated from the stirring material. Therefore, the separation of the materials after stirring requires a separate conveying filter screen for re-separation. Therefore, the industry has put forward some practical requirements for equipment that fully stirs the raw materials before sintering ceramsite. Summary of the invention

[0057] In order to make the purpose, technical solution and advantages of the technical solution more clear, the technical solution is further described in detail below in conjunction with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.

[0058] like Figure 1 As shown, this embodiment proposes an integrated equipment for mixing raw materials for sintering ceramsite. The technical structure of this integrated equipment for mixing raw materials for sintering ceramsite includes a barrel 10, an auger blade 24 and related driving components.

[0059] In one embodiment, the barrel 10 is a cylindrical barrel structure with a closed bottom. In other embodiments, the barrel 10 may also be a material tank. An auger blade 24 is disposed inside the barrel 10, and a driving device for driving the auger blade 24 to rotate is disposed on the top of the barrel 10. In some feasible embodiments, the auger blade 24 is connected to the auger blade 24 after the motor is decelerated and amplified by a reducer, so as to drive the auger blade 24 to rotate.

[0060] In some feasible embodiments, the bottom wall of the inner cavity of the barrel 10 is a plane, the auger blade 24 is a plane edge with a curved lower edge, and the outer edge of the auger blade 24 is adjacent to the inner circumferential wall of the barrel 10. The vertical extension height of the auger blade 24 is approximately 60%-70% of the height of the entire inner cavity of the barrel 10, and the height of the material inside the barrel 10 matches the height of the auger blade 24, so that the auger blade 24 can effectively tumble the material during the rotation process, that is, driven by the auger blade 24, part of the material can pass over the upper edge of the auger blade 24.

[0061] In addition, since the auger blade 24 is a flat edge with a curved lower edge, the outer edge of the auger blade 24 is adjacent to the inner circumferential wall of the barrel 10. Therefore, when the auger blade 24 rotates along the first direction, the material at the edge is driven by the auger blade 24 to gradually move to a position close to the center, and the space left after the material at the edge is removed can be quickly filled with material at other adjacent positions, so that the material in the barrel 10 is fully stirred to achieve a full-range mixing effect in the barrel 10.

[0062] As a preferred embodiment, the mixing method of the barrel 10 and the auger blade 24 described above also has some disadvantages. For example, although the auger blade 24 can achieve full-range mixing in the barrel 10, this mixing generally drives the material to move vertically, and the efficiency of stirring and mixing is not sufficient. To solve this problem, in this embodiment, a plurality of shear rods 12 are provided on the inner wall of the barrel 10, and a avoidance notch 241 corresponding to the position and matching the shape of the shear rod 12 is provided on the auger blade 24. When the material passes through the shear rod 12, it is blocked by the shear rod 12 and cannot move horizontally. The material in the adjacent space can be driven by the auger blade 24 to move in the horizontal direction. Therefore, there is a speed difference in the horizontal direction between the material in the same horizontal space of the shear rod 12 and the material in the adjacent space. Since multiple groups of shear rods 12 with different heights are provided in the barrel 10, and each group of shear rods 12 is also distributed with multiple shear rod 12 monomers, such a speed difference of the horizontal rotation speed of the material is formed in multiple places in the barrel 10.

[0063] Through the above description, the combined stirring effect formed by the auger blade 24 and the shear rod 12 can achieve the stirring of the material in the horizontal direction, and can also achieve the vertical mixing of the material within the barrel 10. The cooperation of the shear rod 12 and the auger blade 24 provides shearing efficiency, so that the ceramsite sintering raw material mixing integrated equipment can increase the horizontal stirring of the material while providing the vertical stirring of the material, and the material can easily achieve the effect of full stirring. The above is the simplest structure to achieve full mixing of the material.

[0064] Generally, the barrel 10 filters the material by opening a mesh plate on the bottom wall of the barrel 10. However, a major problem with this method is that when the auger blades 24 are arranged inside the barrel 10, the rotation of the auger blades 24 has a tendency to lift the material upward. At the same time, the bottom wall area of ​​the barrel 10 is small, so the efficiency of material filtering and screening is relatively low. Therefore, this embodiment proposes a solution of setting a filter mesh tube 11 in the middle of the barrel 10.

[0065] Specifically, the top of the barrel 10 is open, and the driving device of the auger blade 24 includes: a plane gear disc 22, the plane gear disc 22 is located at the top opening of the barrel 10, a plane bearing 13 is arranged on the top of the barrel 10, the plane gear disc 22 is rotationally connected with the barrel 10 through the plane bearing 13, and the outer ring surface of the plane gear disc 22 has a transmission tooth structure; a bidirectional drive motor assembly 21, and the output end of the bidirectional drive motor assembly 21 is transmission-connected with the plane gear disc 22 through the transmission tooth structure; the plane gear disc 22 and the auger blade 24 are connected through the blade connection structure 23.

[0066] Combination Figure 3 As shown, a discharge door 14 is provided near the lower end of the outer ring surface of the barrel 10, and the interior of the barrel 10 also includes: a filter mesh tube 11, which is coaxially arranged with the barrel 10, and the surface of the filter mesh tube 11 is densely covered with filter holes to form a filter screen 111, and the position of the filter mesh tube 11 corresponding to the plane toothed disk 22 of the barrel 10 is hollowed out; and when the auger blades 24 rotate in a first direction, the auger blades 24 push the raw material to be transported toward the central axis; when the auger blades 24 rotate in a second direction, the auger blades 24 push the raw material to be transported toward the peripheral direction.

[0067] The above-mentioned arrangement of the filter mesh tube 11 can significantly increase the filtering area. At the same time, since the interior of the filter mesh tube 11 needs to be used as a channel for material discharge, the auger blade 24 is driven by the flat toothed disc 22 and the blade connecting structure 23. Due to the existence of the blade connecting structure 23, the flat toothed disc 22 can enhance a certain degree of anti-deformation ability, thereby avoiding deformation caused by the weight of the auger blade 24.

[0068] In some feasible embodiments, a plurality of hot dry gas input pipes 15 may be provided on the body of the barrel 10. During the above-mentioned material stirring process, pressurized hot dry gas is input into the material through the hot dry gas input pipes 15. The pressurized hot dry gas can pass through the gaps between the material particles and through the combined action of the stirring of the auger blades 24 to discharge the moisture in the material, which is particularly suitable for mixing slightly humid materials.

[0069] In summary, if a filter mesh tube 11 is provided, the material may be exposed through the filter mesh tube 11 during the rotation of the auger blade 24, so it is necessary to provide a structure for temporarily closing the filter mesh tube 11, that is, to close the material when the auger blade 24 rotates to stir the material, and at the same time, when the material needs to be quickly screened through the filter mesh tube 11, the structure of the closed filter mesh tube 11 is removed. The filter mesh tube 11 and the corresponding structure of the closed filter mesh tube 11 are described in detail below through two embodiments.

[0070] Example 1

[0071] In this embodiment, the filter mesh tube 11 is cylindrical; a support frame 31 is arranged above the barrel 10, and a first hydraulic lifter 32 is arranged on the support frame 31. The telescopic end of the first hydraulic lifter 32 is connected to a sealing tube body 33, and the sealing tube body 33 is installed inside the filter mesh tube 11. The outer diameter of the sealing tube body 33 matches the inner diameter of the filter mesh tube 11, and the length of the sealing tube body 33 matches the length of the filter mesh tube 11; the first hydraulic lifter 32 is used to drive the sealing tube body 33 to move to the filter mesh tube 11 and seal the filter mesh tube 11, or drive the sealing tube body 33 to be removed from the filter mesh tube 11. In this embodiment, a horizontal first connecting beam 34 is arranged inside the sealing tube body 33, and the end of the protruding end of the first hydraulic lifter 32 is connected to the first connecting beam 34. The sealing tube body 33 can be lifted and lowered as a whole by the first hydraulic lifter 32.

[0072] A first cleaning motor 35 is arranged near the lower end of the sealing tube body 33. The output end of the first cleaning motor 35 is a first cleaning motor output shaft 351. The first cleaning motor output shaft 351 is connected to the upper end surface of the columnar cleaning rod 36, and the columnar cleaning rod 36 is coaxially arranged with the filter mesh tube 11. At least one row of first brush strips 361 is arranged outside the columnar cleaning rod 36; the first hydraulic lifter 32 can drive the sealing tube body 33 to rise and fall, so as to switch the sealing tube body 33 or the columnar cleaning rod 36 to face the filter mesh tube 11.

[0073] The method of using the integrated equipment for mixing raw materials for sintering ceramsite is as follows: step A1: driving the sealing tube body 33 to move to the corresponding filter mesh tube 11 through the first hydraulic lifter 32 and closing the filter mesh tube 11; step A2: inputting the material to be mixed into the inner cavity of the barrel 10, and driving the auger blade 24 to rotate in the first direction through the bidirectional drive motor assembly 21 during the material input process, and after the input of the predetermined volume of material is completed, continuously driving the auger blade 24 to rotate to the predetermined mixing time, and mixing the material during the rotation of the auger blade 24 and shearing the material through the cooperation of the shear rod 12 and the auger blade 24; Figure 2 As shown, step A3: when the predetermined mixing time is reached, the sealing tube body 33 is driven to be lifted by the first hydraulic lifter 32, and the columnar cleaning rod 36 is moved to the corresponding position of the filter mesh tube 11, and the auger blade 24 is driven to rotate continuously, forcing the material to be discharged through the filter mesh tube 11. If the material discharge speed of the filter mesh tube 11 is reduced, the columnar cleaning rod 36 is driven to rotate by the first cleaning motor 35, and the blocked mesh of the filter mesh tube 11 is cleaned by the first brush strip 361 until no material is discharged from the filter mesh tube 11, and the filtered bulk material remains in the barrel 10; step A4: the auger blade 24 is driven to rotate in the opposite direction by the bidirectional drive motor assembly 21, and the discharge door 14 is opened at this time to discharge the bulk material remaining in the barrel 10.

[0074] It should be noted that in Example 1, when the auger blades 24 drive the material to pass through the filter mesh tube 11, the auger blades 24 rotate in the first direction, which can provide a force for the material to gather upward and toward the center. Therefore, when there is a lot of material, the material is squeezed and disturbed, and can quickly flow out through the filter mesh tube 11. When there is less material, the material is lifted and distributed upward by the auger blades 24, and the effective filtering area of ​​the filter mesh tube 11 can be fully utilized.

[0075] Example 2

[0076] In this embodiment, in order to optimize the effect of filtering materials by the filter mesh tube 11, the shape and structure of the filter mesh tube 11 are changed, and the structure of the temporarily closed filter mesh tube 11 is optimized. The barrel 10, the auger blade 24, the shear rod 12 and the bidirectional drive motor assembly 21 for driving the auger blade 24 to rotate are not changed.

[0077] Specifically, Figure 4 and Figure 5 As shown, the filter mesh tube 11 is in the shape of a truncated cone, and the diameter of the filter mesh tube 11 gradually increases from top to bottom; the inside of the filter mesh tube 11 has a removable conical sealing body 48, and the conical sealing body 48 can be attached to the inner wall of the filter mesh tube 11 to close the filter mesh tube 11.

[0078] In this embodiment, the filter mesh tube 11 is in the shape of a truncated cone, which has two advantages. First, the filter mesh tube 11 is in the shape of a truncated cone, which can be driven and distributed on the filter mesh tube 11 by the auger blades 24. The material can flow downward by its own gravity, and the material can be evenly distributed on the surface of the filter mesh tube 11. At the same time, the material can also pass through the holes on the filter mesh tube 11 more easily. Secondly, the filter mesh tube 11 is in the shape of a truncated cone, which can reduce the overall height of the components that drive the conical sealing body 48 to rise and fall, that is, the conical sealing body 48 can form a material outflow gap A by descending a small distance, that is, forming a gap such as Figure 8 The effect is shown.

[0079] In this embodiment, a base 41 is provided below the filter mesh tube 11, a second hydraulic lifter 42 is provided on the top surface of the base 41, a lifting platform 43 is connected to the telescopic end of the second hydraulic lifter 42, a support structure 45 is provided on the lifting platform 43, and the support structure 45 is connected to the inner wall of the conical sealing body 48. The above structure can realize the overall lifting of the conical sealing body 48 to a predetermined height.

[0080] The support structure 45 is rotatably connected to the conical sealing body 48 via a bearing member 47; a second cleaning motor 44 is arranged on the lifting platform 43, and an output shaft of the second cleaning motor 44 is coaxially arranged with the conical sealing body 48. A second connecting beam 46 is arranged inside the conical sealing body 48, and an output shaft of the second cleaning motor 44 is connected to the second connecting beam 46 to drive the conical sealing body 48 to rotate via the second cleaning motor 44.

[0081] Combination Figure 6 and Figure 7 As shown, the surface of the filter screen tube 11 has a plurality of avoidance strips 112 without holes arranged along the generatrix direction thereof, and the outer side of the conical sealing body 48 is conically provided with a plurality of grooves 481 arranged along the generatrix direction thereof, and the grooves 481 correspond to the avoidance strips 112 in position, and a second brush strip 482 is arranged inside each groove 481. Figure 4 As shown, when the conical sealing body 48 rises to abut against the inner wall of the filter screen tube 11, the second brush strip 482 corresponds to the position of the avoidance strip plate 112. The avoidance strip plate 112 can form a certain bending effect on the end of the second brush strip 482 to prevent the second brush strip 482 from breaking or being pinched off. At this time, the second brush strip 482 is as shown in FIG. Fig. 9 The status shown. Figure 5 As shown, when the conical seal 48 is lowered to a predetermined position, a material outflow gap A is formed between the conical seal 48 and the filter screen tube 11. At this time, the conical seal 48 is rotated, and the second brush strip 482 in the groove 481 of the conical seal 48 can clean the filter screen 111 on the filter screen tube 11.

[0082] Therefore, the method of using the ceramsite sintering raw material mixing integrated equipment in Example 2 is as follows: Step B1: Drive the conical sealing body 48 to rotate to the position where the avoidance strip 112 is opposite to the groove 481 through the second hydraulic lifter 42, and drive the conical sealing body 48 to move up through the second hydraulic lifter 42, and seal the outer annular surface of the conical sealing body 48 at the filter screen 111, and the avoidance strip 112 closes the groove 481; Step B2: Input the material to be mixed into the inner cavity of the barrel 10, and drive the auger blade 24 to rotate in the first direction through the bidirectional drive motor assembly 21 during the material input process. After the predetermined volume of material is input, continue to drive the auger blade 24 to rotate to the predetermined mixing time, and during the rotation of the auger blade 24, mix the material and pass it through the shear rod 1 2 and the auger blade 24 cooperate to shear the material; step B3: when the predetermined mixing time is reached, the conical sealing body 48 is driven downward by the second hydraulic lifter 42 to form a material outflow gap A between the conical sealing body 48 and the filter mesh tube 11, and the auger blade 24 is driven to rotate continuously, forcing the material to be discharged through the filter mesh tube 11. If the material discharge speed of the filter mesh tube 11 is reduced, the second cleaning motor 44 drives the conical sealing body 48 to rotate, and the second brush strip 482 cleans the blocked mesh of the filter mesh tube 11 until no material is discharged from the filter mesh tube 11, and the filtered bulk material remains in the barrel 10; step B4: the bidirectional drive motor assembly 21 drives the auger blade 24 to rotate in the opposite direction to discharge the bulk material remaining in the barrel 10.

[0083] The ceramsite sintering raw material mixing integrated equipment also achieves the effect of the process through the filter mesh tube 11, the filter mesh tube 11 increases the filtering area, and the ceramsite sintering raw material mixing integrated equipment simultaneously completes the effects of material mixing and stirring and agglomerated material filtering and separation. The ceramsite sintering raw material mixing integrated equipment can be used for a long time without maintenance, has a simple structure, and has a low production cost, and is suitable for integrated use of mixing and stirring and material filtering.

[0084] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
