Description

Technical Field

[0001] This utility model relates to the field of automatic slag discharge machine technology, and in particular to a double helical screw for an automatic slag discharge machine. Background Technology

[0002] The twin-screw mechanism of an automatic slag discharger is a mechanical component used for material conveying and slag discharge, typically for handling solid waste or slag generated in industrial processes. It utilizes two helical screws working together to transport materials or slag from one location to another, achieving the purpose of removal, cleaning, or separation. The twin-screw design is generally used to improve slag discharge efficiency, reduce the risk of material blockage, and increase equipment reliability.

[0003] In automatic slag discharge machines, twin helical screws are typically responsible for pushing and discharging slag from the processing tank or container. However, the spacing between the twin helical screws inside existing automatic slag discharge machines is generally fixed, making it impossible to adjust the screw's working state according to different material characteristics, particle size, or viscosity. Since different materials may require different screw spacings to achieve the best slag discharge effect, if the screw spacing cannot be adjusted, the equipment cannot optimize its operation according to the actual situation, affecting production efficiency. Furthermore, the existing screw fixing methods are generally cumbersome, making disassembly and maintenance troublesome and affecting maintenance efficiency. Utility Model Content

[0029] Example 1

[0030] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a double helical screw for an automatic slag discharger. The double helical screw for the automatic slag discharger includes a conveying assembly 100 and an auxiliary assembly 200. The conveying assembly 100 facilitates the installation, quick disassembly, and driving of the screw rods 105. The auxiliary assembly 200 allows for adjustment of the distance between the two screw rods 105, the first motor 108, and the fixing plate 104. The working mode of the screw can be flexibly adjusted as needed. Adjusting the distance helps optimize slag discharge efficiency, avoids material blockage or poor flow, and can adapt to more operating scenarios.

[0031] The conveying assembly 100 includes a conveying shell 101, support legs 102, a cover plate 103, a fixing plate 104, a screw rod 105, a positioning shell 106, a mounting component 107, and a first motor 108. The support legs 102 are fixed to the four corners of the bottom of the conveying shell 101. The cover plate 103 is hinged to the top of the conveying shell 101. The fixing plate 104 is disposed on the front and rear sides of one side of the conveying shell 101. The screw rod 105 is disposed inside the conveying shell 101. The positioning shell 106 is fixed to the drive rod of the first motor 108. The mounting component 107 is disposed inside the positioning shell 106.

[0032] The support leg 102 provides convenient support for the bottom of the conveyor shell 101, and a discharge port is provided on one side of the bottom of the conveyor shell 101 for use with the screw rod 105 for material discharge. The cover plate 103 is hinged to the top of the conveyor shell 101 to facilitate internal maintenance by the staff. The fixing plate 104 facilitates the fixing of the first motor 108, and the output end of the first motor 108 is fixedly connected to the positioning shell 106. The screw rod 105 is installed and fixed through the mounting part 107 inside the positioning shell 106. Thus, the first motor 108 can drive the positioning shell 106 to rotate the screw rod 105 for conveying work.

[0033] The auxiliary component 200 is disposed on one side of the conveying shell 101 and includes an extension plate 201, a driving component 202, a sliding block 203, a limiting plate 204, and a positioning component 205. The extension plate 201 is fixed to the front and rear sides of one side of the conveying shell 101, the driving component 202 is fixed to one side of the extension plate 201, the sliding block 203 is disposed on the front and rear sides of one side inside the conveying shell 101, and one side is movable and abuts against the screw rod 105, the limiting plate 204 is fixedly connected to both sides of the sliding block 203 through bearing rings, and the positioning component 205 is disposed inside the limiting plate 204.

[0034] The extension plate 201 facilitates the fixing of the drive component 202, while the drive component 202 facilitates the adjustment of the position between the two fixing plates 104 and synchronously drives the first motor 108 and the screw rod 105 to adjust the distance. The sliding block 203, in conjunction with the positioning component 205, can fix the other end of the screw rod 105 and assist the screw rod 105 to move in parallel.

[0035] Example 2

[0036] Reference Figure 3 , Figure 4 and Figure 5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, the conveying assembly 100 also includes a snap-fit ​​body 109 and a feed housing 110. The snap-fit ​​body 109 is respectively disposed on one side of the cover plate 103 and the conveying housing 101, and the feed housing 110 is fixed to one side of the top of the cover plate 103.

[0038] The clip body 109 is fixed to one side of the cover plate 103 and the conveying shell 101 respectively, which facilitates locking and fixing between the cover plate 103 and the conveying shell 101, reducing the spread of dust to the outside of the conveying shell 101, and the feeding shell 110 facilitates the guiding and feeding of conveying materials.

[0039] Specifically, the auxiliary component 200 also includes a chute 206, which is opened on one side inside the conveyor housing 101 and is slidably connected to the sliding block 203 inside.

[0040] By having a groove 206 formed inside the conveying housing 101 and slidably connected to the sliding block 203, the movement of the sliding block 203 inside the conveying housing 101 can be limited.

[0041] Specifically, the mounting component 107 includes an insert block 107a, a pull rod 107b, a pull ring 107c, a slot 107d, and a spring 107e. The insert block 107a is disposed inside the positioning shell 106. The pull rod 107b is fixed to one end of the insert block 107a, and the other end extends to the outside of the positioning shell 106. The pull ring 107c is fixed to one end of the pull rod 107b. The slot 107d is opened on the front and rear sides of the screw rod 105. The spring 107e is fixed between the insert block 107a and the positioning shell 106.

[0042] The slots 107d are opened on the front and rear sides of the screw rod 105, and the insert block 107a fits into the inside of the slot 107d. When the screw rod 105 is installed flat inside the positioning shell 106, the inclined surface of the insert block 107a will be compressed by the spring 107e, and the pull rod 107b will be pressed to one side until the slot 107d on the screw rod 105 is completely fitted into the inside of the insert block 107a, thus completing the installation work at one end.

[0043] Specifically, the auxiliary component 200 also includes a reinforcing block 207, which is fixed to one side of the extension plate 201 and fixedly connected to the conveying shell 101 on the other side.

[0044] By fixing the reinforcing block 207 between the extension plate 201 and the conveying shell 101, the connection strength between the two can be improved.

[0045] Specifically, the drive component 202 includes a second motor 202a, a bidirectional lead screw 202b, and a threaded sleeve 202c. The second motor 202a is fixed to one side of the extension plate 201, and its output end extends through to one side of the extension plate 201 and is fixedly connected to the bidirectional lead screw 202b. The threaded sleeve 202c is threadedly connected to both sides of the surface of the bidirectional lead screw 202b, and its top is fixedly connected to the fixing plate 104.

[0046] By opening the output end of the second motor 202a, the bidirectional lead screw 202b can be driven to rotate. When the bidirectional lead screw 202b rotates, the two threaded sleeves 202c will move relative to each other, and synchronously drive the fixed plate 104 and the first motor 108 to move relative to each other or in opposite directions to adjust the spacing of the screw rod 105. By adjusting the spacing of the screw rod 105, unnecessary friction can be reduced, the wear rate of the screw can be reduced, and the service life of the screw can be extended.

[0047] Specifically, the drive component 202 also includes a sliding sleeve 202d and a sliding rod 202e. The sliding sleeve 202d is fixed to one side of the threaded sleeve 202c and is slidably connected to the surface of the sliding rod 202e. The two ends of the sliding rod 202e are respectively fixedly connected to the extension plate 201.

[0048] By sliding the sliding sleeve 202d and the sliding rod 202e, the stability of the threaded sleeve 202c during movement can be improved, and the movement path of the threaded sleeve 202c can be limited.

[0049] Example 3

[0050] Reference Figure 5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0051] Specifically, the positioning component 205 includes a screw 205a, a torsion block 205b, and an insert rod 205c. The screw 205a is rotatably connected to the inside of the limiting plate 204, and one end is fixedly connected to the screw 205a. The insert rod 205c is rotatably connected to one end of the screw 205a through a bearing.

[0052] When the user needs to install the other end of the screw rod 105, the torsion block 205b can be rotated to rotate the screw rod 205a. As the screw rod 205a rotates, the insertion rod 205c will slowly move to one side and be inserted into the screw rod 105, thereby completing the installation.

[0053] Specifically, the positioning component 205 also includes a limiting block 205d and a limiting groove 205e. The limiting block 205d is fixed to one side of the bottom of the insertion rod 205c, and the limiting groove 205e is opened inside the limiting plate 204 and is slidably connected to the surface of the limiting block 205d.

[0054] By fixing the limiting block 205d to the insertion rod 205c and sliding it inside the limiting groove 205e, the position of the insertion rod 205c can be limited and guided, preventing the insertion rod 205c from failing to align with the slot on the screw rod 105.

[0055] Specifically, the auxiliary component 200 also includes a reinforcing block 208, which is fixed to one side of the bottom of the limiting plate 204 and is fixedly connected to the sliding block 203 on one side.

[0056] By fixing the reinforcing block 208 between the limiting plate 204 and the sliding block 203, the connection strength between the limiting plate 204 and the sliding block 203 can be improved, the compressive strength between the limiting plate 204 and the sliding block 203 can be improved, and the stability of the positioning component 205 can be guaranteed.

[0057] In use, first install the screw rod 105, open the cover plate 103, and then insert the screw rod 105 by aligning both ends with the positioning shell 106 and the sliding block 203 respectively. At this time, the screw rod 105 is inserted through the slots 107d on the front and rear sides, and the insert block 107a fits into the inside of the slot 107d. When the screw rod 105 is placed flat inside the positioning shell 106, the inclined surface of the insert block 107a will be compressed by the spring 107e, and simultaneously the pull rod 107b will be pressed to one side and moved. The installation of one end is complete when the slot 107d on the screw rod 105 is fully engaged with the interior of the insert block 107a. When the user needs to install the other end of the screw rod 105, the torsion block 205b can be rotated to rotate the screw rod 205a. As the screw rod 205a rotates, the insert rod 205c will slowly move to one side. As the insert rod 205c moves, it will cause the limiting block 205d to move within the limiting groove 205e, thus limiting its movement. Subsequently, the insert rod 205c will be inserted into the pre-set... The screw rod 105 is installed inside the slot. Then, driven by the first motor 108, the positioning shell 106 and the screw rod 105 rotate. The sliding block 203, in conjunction with the limiting plate 204 and the positioning element 205, assists the rotation of the screw rod 105 at one end of the sliding block 203. If the user needs to adjust the distance between the two screw rods 105, the output end of the second motor 202a can be turned to drive the bidirectional lead screw 202b to rotate. When the bidirectional lead screw 202b rotates, the two threaded sleeves 202c will move relative to each other. As the threaded sleeves 202c move, the sliding sleeve 202d will move to a limit position on the surface of the sliding rod 202e, and simultaneously drive the fixing plate 104 and the first motor 108 to move relative to each other or in opposite directions to adjust the distance between the screw rods 105. However, when the screw rods 105 move, they will cause friction. By adjusting the distance between the screw rods 105, unnecessary friction can be reduced, the wear rate of the screw can be reduced, and the service life of the screw can be extended.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
