Description

Technical Field

[0001] This utility model relates to the field of rotary cooling cylinder technology, and in particular to a rotary cylinder cooler. Background Technology

[0002] A rotary cooling cylinder, also known as a drum cooler, is a device used for cooling materials. Its working principle involves lifting plates inside the cylinder turning the material upside down, allowing it to fully contact the cold air and thus achieving a cooling effect. Material is added from the feed end, and the suction generated by the fan inside the cylinder accelerates the airflow. The lifting plates continuously turn the material upside down, and the cooled material flows out from the discharge port.

[0003] A prior art display (CN220582826U) describes a screening-type cylindrical cooler, comprising a rotating drum, a feeding assembly, a discharging assembly, a recovery assembly, a support roller assembly, a drive assembly, a spray assembly, and a pendulum assembly. This invention features a discharge screening drum with elongated, densely packed screen holes arranged according to the rotation direction of the cylindrical cooler.

[0004] This device can screen materials, but its screen cylinder can only achieve single-size grading (such as separating fine materials below 3mm), which cannot meet the needs of materials requiring multi-stage screening (such as coarse, medium, and fine grading). In practical applications, if materials need to be further classified according to different particle sizes, additional screening equipment must be configured for secondary or multiple screenings. This not only increases equipment investment and space occupation but also reduces the overall efficiency of the device, failing to fully achieve the optimization goal of "one-stop" processing. Utility Model Content

[0005] This utility model is a rotary cylindrical cooler proposed to overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rotary cylindrical cooler, comprising a cooler body, wherein the discharge end of the cooler body is provided with multiple screening mechanisms;

[0007] A support frame is fixedly installed at the bottom of the cooler body, and an annular tongue is fixedly connected to the discharge end of the cooler body. The outer surface of the annular tongue is provided with multiple positioning rods, and the positioning rods are fixedly connected to the cooler body.

[0008] Each of the screening mechanisms includes a base, the base is equipped with a positioning clamping assembly, and a material hopper is fixedly connected to the top of the inner walls on both sides of the base. Two mounting rings are symmetrically and slidably embedded in the inner surface of the material hopper, and an annular filter cartridge is detachably and fixedly installed on the two mounting rings.

[0009] An annular mating groove is provided on the inner surface of a single mounting ring located on one side of the cooler body, and multiple positioning holes are provided on one side of the outer surface of a single mounting ring located on one side of the cooler body.

[0010] Multiple limiting rods are uniformly fixedly connected to one side of the outer surface of another single mounting ring. A mating tongue is provided between the multiple limiting rods, and the mating tongue is fixedly connected to the adjacent mounting ring.

[0011] Furthermore, the support frame includes a frame, which is fixedly installed at the bottom of the cooling machine body. One end of the frame is fixedly connected to a connecting frame, which facilitates the docking of the frame and the base through a positioning clamping assembly.

[0012] Furthermore, the positioning and clamping assembly includes a bidirectional screw that passes through the base and is rotatably connected to the base. Two clamping blocks are symmetrically threaded onto the outer surface of the bidirectional screw, and the clamping blocks slide against the inner wall of the base. A handwheel is fixedly connected to one end of the bidirectional screw, which facilitates manual driving of the bidirectional screw.

[0013] Furthermore, the hopper includes an arc-shaped hopper, which is fixedly connected to the base. The arc-shaped hopper is slidably connected to two mounting rings for limiting. A discharge pipe is fixedly connected to one side of the bottom of the arc-shaped hopper, and the discharge pipe facilitates the discharge of the screened material.

[0014] Furthermore, both mounting rings are fixedly connected to the inner surface of the annular filter cylinder with inclined plates, which can be used to rotate the annular filter cylinder to lift and move the material.

[0015] Furthermore, the two mounting rings are fixedly connected to the annular filter cartridge by multiple bolts, which facilitates the installation and disassembly of the annular filter cartridge.

[0016] The beneficial effects of this utility model are:

[0017] In use, this rotary cylindrical cooler, through its support frame, annular tongue, positioning rod, base, positioning clamping assembly, hopper, mounting ring, annular filter cylinder, annular docking groove, positioning hole, limiting rod, and docking tongue, forms an expandable screening unit group. Users can freely increase or decrease the number of screening mechanisms according to material grading requirements. Each screening mechanism corresponds to different screen aperture specifications, enabling multi-stage screening (such as coarse, medium, and fine separation) to be completed in a single processing step. This structure completely avoids the drawbacks of traditional equipment requiring secondary screening, achieving graded cooling through one-stop discharge, significantly reducing equipment investment and space occupation, while improving screening efficiency and process adaptability.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 3 As shown, a rotary cylindrical cooler is disclosed, including a cooler body 1, wherein the discharge end of the cooler body 1 is provided with multiple screening mechanisms.

[0026] A support frame is fixedly installed at the bottom of the cooler body 1. The support frame includes a frame 2, which is fixedly installed at the bottom of the cooler body 1. The frame 2 can raise the height of the cooler body 1, which is conducive to the connection between the cooler body 1 and the screening mechanism. A connecting frame 5 is fixedly connected to one end of the frame 2. An annular tongue 6 is fixedly connected to the discharge end of the cooler body 1. The outer surface of the annular tongue 6 is provided with multiple positioning rods 7, and the positioning rods 7 are fixedly connected to the cooler body 1. The positioning rods 7 facilitate the positioning and connection of the cooler body 1, and the annular tongue 6 ensures that the material can smoothly enter the screening mechanism.

[0027] Each of the screening mechanisms includes a base 15, on which a positioning and clamping assembly is mounted. The positioning and clamping assembly includes a bidirectional screw 17, which passes through the base 15 and is rotatably connected to it. The outer surface of the bidirectional screw 17 is provided with a limiting annular protrusion, which is rotatably and slidably embedded in the inner side of the base 15, thereby realizing the rotatable connection between the bidirectional screw 17 and the base 15. At the same time, the thread helix angle of the bidirectional screw 17 is less than the friction angle, and the screw has a self-locking capability, which can prevent it from shifting due to vibration or load. Two clamping blocks 16 are symmetrically threaded on the outer surface of the bidirectional screw 17, and the clamping blocks 16 slide against the inner wall of the base 15. A handwheel 18 is fixedly connected to one end of the bidirectional screw 17. The base 15 has a limiting effect on the clamping blocks 16, which can ensure the stability of the movement of the clamping blocks 16.

[0028] The top of the inner walls on both sides of the base 15 are fixedly connected to a hopper. Two mounting rings 11 are symmetrically and slidably fitted into the inner surface of the hopper. The hopper includes an arc-shaped hopper 3, which is fixedly connected to the base 15. The arc-shaped hopper 3 is slidably connected to the two mounting rings 11. A discharge pipe 4 is fixedly connected to one side of the bottom of the arc-shaped hopper 3. Two sets of supporting steel balls abut against the inner and outer surfaces of the mounting rings 11. The two sets of supporting steel balls located inside the mounting rings 11 are rotatably fitted into the inner wall of one side of the connecting groove between the arc-shaped hopper 3 and the mounting rings 11. The remaining two sets of supporting steel balls are rotatably fitted into the inner wall of the other side of the connecting groove, which can reduce the rotational friction of the mounting rings 11.

[0029] The two mounting rings 11 are detachably and fixedly mounted on the annular filter cartridge 12. The aperture size of the annular filter cartridge 12 can be selected as needed. The two mounting rings 11 and the annular filter cartridge 12 are fixedly connected by multiple bolts. The bolt connection design facilitates the disassembly and replacement of the annular filter cartridge 12.

[0030] An annular docking groove 10 is provided on the inner surface of a single mounting ring 11 located on one side of the cooler body 1, and multiple positioning holes 9 are provided on one side of the outer surface of a single mounting ring 11 located on one side of the cooler body 1. The setting of the annular docking groove 10 and the positioning holes 9 facilitates the docking operation.

[0031] A plurality of limiting rods 14 are uniformly fixedly connected to one side of the outer surface of another single mounting ring 11. A mating tongue 13 is provided between the plurality of limiting rods 14, and the mating tongue 13 is fixedly connected to the adjacent mounting ring 11. The setting of the mating tongue 13 and the limiting rods 14 facilitates the docking of two adjacent screening mechanisms.

[0032] Both mounting rings 11 and the inner surface of the annular filter cartridge 12 are fixedly connected with inclined plates 8.

[0033] Material conveying and cooling:

[0034] High-temperature materials enter from the feed end of the cooler body 1 and are continuously tumbled by the lifting plates as the cylinder rotates.

[0035] The cooling machine body 1 cools the material inside the cylinder (the specific process is existing technology and is not shown in the figure), so that the material is cooled evenly during the movement.

[0036] Modular screening mechanism docking

[0037] Multiple screening mechanisms are arranged in series along the discharge end. The screening mechanism located on one side of the cooler body 1 achieves radial positioning and docking through annular tongue 6, positioning rod 7, annular docking groove 10 and positioning hole 9. Adjacent screening mechanisms achieve radial positioning and docking through limiting rod 14, docking tongue 13, annular docking groove 10 and positioning hole 9 (the gap generated by docking can be compensated by installing an existing annular rubber gasket to ensure the sealing of the docking point. Specifically, the annular rubber gasket can be fixed to the docking tongue 13 and annular tongue 6 and abut against the inner wall of the adjacent annular docking groove 10).

[0038] The handwheel 18 drives the bidirectional screw 17 to rotate, and the bidirectional screw 17 drives the clamping block 16 to clamp the base 15 or connecting frame 5 of another screening mechanism, thereby fixing the screening mechanisms together and fixing the screening mechanism to the cooler body 1.

[0039] Multi-stage particle size screening

[0040] The cooled material enters the first-stage annular filter cartridge 12, and the fine particles fall into the arc-shaped chamber 3 through the sieve holes and are discharged through the discharge pipe 4.

[0041] Larger particles that have not passed through the sieve continue to move to the next stage of the filter cartridge, passing through filter cartridges with different pore sizes (such as medium pores and coarse pores) in sequence, thus achieving multi-stage classification.

[0042] Each filter cartridge is equipped with inclined plates 8 to guide the material to be evenly distributed and extend the screening path, thereby improving the screening throughput.

[0043] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
