Description

Technical Field

[0001] This utility model relates to the field of fly ash brick production technology, and in particular to a raw material refining device for autoclaved brick production. Background Technology

[0002] The main raw materials for fly ash bricks are industrial waste solids such as fly ash, lime, gypsum, carbide slag, and carbide sludge. Solid fly ash bricks are made by preparing raw materials using fly ash and lime as the main raw materials, adding appropriate amounts of gypsum and aggregates, pressing them into shape, and curing them under high or normal pressure steam. The production process of fly ash bricks requires refining the raw materials. Refining the raw materials can further improve product quality. However, in existing refining devices, the filter plates used to filter the raw materials are prone to clogging during use, affecting the refining efficiency.

[0003] For example, a raw material refining device for autoclaved fly ash brick production disclosed in Chinese patent literature (publication number: CN218609711U) uses a structure such as a spring, inclined ring and drive block on the vibratory plate. During the process of refining the raw material by the crushing blade, the drive block can rotate along the inclined ring and push the vibratory plate up and down through the inclined ring. The spring force drives the vibratory plate to vibrate, which can make the raw material on the filter screen vibrate, thus effectively preventing the raw material from clogging the filter screen.

[0004] However, in actual use, the filter screen vibrates back and forth, and during this vibration, it is easily squeezed by the rotating crushing blades. This causes some large particles to be squeezed into the filter holes and become clogged. This clog is difficult to discharge by vibration alone, resulting in frequent manual unclogging, which greatly reduces the efficiency of raw material refining. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. In actual use, the filter screen vibrates back and forth, and during this vibration, it is easily squeezed by the rotating crushing blades. This causes some large particles to be squeezed into the filter holes and become clogged. This clog is difficult to clear by vibration alone, resulting in frequent manual unclogging, which greatly reduces the efficiency of raw material refining.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0027] Example

[0028] like Figure 1-5 As shown, this utility model provides a technical solution: a raw material refining device for autoclaved brick production, including a refining tank 1, a support block 2 arranged in a ring array fixedly connected to the inner wall of the refining tank 1, a guide rod 3 fixedly connected to the upper surface of the support block 2, a guide block 4 movably sleeved on the outer surface of the guide rod 3, a return spring 5 movably sleeved on the outer surface of the guide rod 3, one end of the return spring 5 fixedly connected to the upper surface of the support block 2, and the other end of the return spring 5 fixedly connected to the lower surface of the guide block 4, a conical unblocking disc 6 fixedly connected to one end of each of the multiple guide blocks 4, the upper end of the conical unblocking disc 6 being conical and inclined, thereby ensuring that the material falling to the upper end can slide out, and an unblocking rod 7 arranged in a ring array fixedly connected to the upper end of the conical unblocking disc 6;

[0029] The interior of the refining tank 1 is equipped with a reciprocating unblocking device, which includes a sieve plate 8. The outer surface of the sieve plate 8 is fixedly sleeved with the inner wall of the refining tank 1.

[0030] The lower surface of the conical unclog plate 6 is fixedly connected with inclined extrusion blocks 81 arranged in a ring array, and the upper surface of the sieve plate 8 is fixedly connected with a conical guide ring 82.

[0031] The upper end of the conical guide ring 82 is fixedly sleeved with the inner wall of the refining tank 1, and the lower end of the refining tank 1 is fixedly connected to the discharge pipe 83. A servo motor 84 is fixedly installed on the upper surface of the refining tank 1. The conical guide ring 82 guides and refines the incoming raw material.

[0032] The output shaft of the servo motor 84 is fixedly mounted with a rotating shaft 85 via a coupling. One end of the rotating shaft 85 passes through the screen plate 8 and the conical dredging disc 6 and extends into the interior of the discharge pipe 83. The outer surface of the rotating shaft 85 is fixedly connected with crushing blades 86 arranged in a ring array. The crushing blades 86 are divided into three groups, and the adjacent groups are staggered to improve the fineness efficiency.

[0033] The outer surface of the rotating shaft 85 is fixedly connected with symmetrically distributed support rods 87. One end of the outer surface of the support rod 87 is fitted with a compression sleeve 88 through a bearing. One end of the outer surface of the rotating shaft 85 is fixedly fitted with a spiral blade 89. The compression sleeve 88 rotates through the bearing during compression contact, thereby reducing compression friction.

[0034] The outer surface of the spiral blade 89 is in contact with the inner wall of the discharge pipe 83. The upper surface of the refining tank 1 is fixedly connected to the feed hopper 810. The front inner wall of the feed hopper 810 is fixedly connected to the baffle 811. The inner walls on both sides of the feed hopper 810 are equipped with rotating rods 812 through bearings. The outer surface of the rotating rod 812 is fixedly sleeved with a rotating block 813. The baffle 811 serves to block the gaps on both sides of the rotating block 813.

[0035] A torsion spring 814 is symmetrically distributed and movably sleeved on the outer surface of the rotating rod 812. One end of the torsion spring 814 is fixedly connected to one side surface of the rotating block 813, and the other end of the torsion spring 814 is fixedly connected to one side inner wall of the feed hopper 810. A swing plate 815 is fixedly connected to one end of the rotating block 813. One end of the swing plate 815 contacts the rear inner wall of the feed hopper 810. The swing plate 815 serves to seal the smoke and dust overflowing from the feed hopper 810 and improve the working environment.

[0036] The reciprocating unblocking device enables the unblocking rod 7 to move back and forth by driving the conical unblocking disc 6. The unblocking rod 7 is inserted into the corresponding screen hole of the screen plate 8 for forced unblocking, thereby avoiding blockage and ensuring the effect of raw material refining. In addition, the swing plate 815 blocks the feed hopper 810, thereby reducing the smoke and dust overflow generated during raw material refining and improving the working environment.

[0037] The working process of this utility model:

[0038] Step 1: Add the raw material to the feed hopper 810. The gravity of the raw material causes the swing plate 815 to drive the rotating block 813 to squeeze and rotate. When the raw material is added into the fine tank 1, the torsion of the torsion spring 814 drives the swing plate 815 to reset and rotate through the rotating rod 812 and the rotating block 813, thereby blocking the feed hopper 810, reducing the amount of dust overflowing during raw material crushing, and improving the working environment.

[0039] Step 2: Start the servo motor 84 to drive the rotating shaft 85 to rotate. The rotation of the rotating shaft 85 finely crushes the raw material through the crushing blade 86. The finely crushed raw material falls into the discharge pipe 83 through the screen holes of the screen plate 8, and is forced to be discharged by the rotation of the spiral blade 89 to avoid blockage. The rotation of the rotating shaft 85 drives the extrusion sleeve 88 to rotate through the support rod 87. The rotation of the extrusion sleeve 88 will extrude the inclined extrusion block 81, thereby causing the conical unblocking disc 6 to drive the unblocking rod 7 to rise and move.

[0040] Step 3: The upward movement of the unblocking rod 7 causes it to be inserted into the sieve hole of the sieve plate 8 for forced unblocking. The upward movement of the conical unblocking disc 6 drives the return spring 5 to be stretched through the guide block 4. When the extrusion sleeve 88 rotates to disengage from the inclined extrusion block 81, the elastic force of the return spring 5 drives the unblocking rod 7 on the conical unblocking disc 6 to descend and reset through the guide block 4.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
