[0036] Due to the influence of site conditions, the moisture and impurities in the materials are to a certain extent beyond human control. In the process of conveying with the drainage chute, it is inevitable to encounter problems such as excessive moisture in the powder and agglomeration. As a result, material accumulation often occurs around the inner cavity of the discharge chute, which shrinks the chute mouth, causing large pieces of material to be stuck or a slightly larger material flow rate will cause blockage, affecting the production operation of the unloading process.
[0037] The utility model provides a discharging chute.
[0038] See also Figure 1 In one embodiment of the present utility model, the unloading chute 100 comprises:
[0039] The chute body 1 has a material cavity; and
[0040] The dredging structure 2 extends into the material cavity and is rotatably connected to the chute body 1 so that the material in the material cavity can be stirred or crushed by the rotation of the dredging structure 2.
[0041] In the technical solution of the utility model, a material cavity is formed inside the chute body 1, which is used as a medium to transport powdered materials. During the unloading process, it is easy to encounter problems such as excessive moisture in the powder and agglomeration, which leads to blockage in the powder transportation. In this solution, a dredging structure 2 extending into the material cavity is provided, and the dredging structure 2 is rotatably connected to the chute body 1, so that the material in the material cavity is stirred or crushed by the rotation of the dredging structure 2. When the material cavity is blocked, the material can be stopped from being added to the chute body 1 in time, and the material in the material cavity will no longer increase. At this time, the user can rotate the dredging structure 2 again to stir or crush the large pieces of material in the material cavity, thereby completing the cleaning of the chute body 1 blocked by the material. This solution can timely dredge the material blocked in the material cavity, avoid affecting the normal unloading work due to the blockage of the material cavity, and thus improve production efficiency.
[0042] Specifically, the specific structure of the dredging structure 2 is not specifically limited in the present solution. For example, it can be a stirring rod, and the end of the stirring rod extending into the material chamber can be provided with a stirring paddle, or it can be provided with a crushing hammer, etc., as long as it can play the role of crushing or stirring the agglomerated powder. Optionally, the dredging structure 2 is made of high-strength stainless steel. For the connection between the dredging structure 2 and the chute body 1, a mounting keyway can be provided on the chute body 1, and an internal thread can be provided in the mounting keyway, so that the internal thread can be threadedly connected to the external thread on the dredging structure 2, thereby realizing the rotational connection of the dredging structure 2, and the length thereof extending into the material chamber can be adjusted.
[0043] In one embodiment, see Figures 2 to 4 , the dredging structure 2 includes:
[0044] A rotating rod 21, the rotating rod 21 is rotatably connected to the chute body 1, and the rotating rod 21 includes a dredging end 211 extending into the material cavity and a rotating end 212 disposed outside the chute body 1; and
[0045] The dredging member 22 is disposed at the dredging end 211 and is used to stir or crush the agglomerated materials in the material cavity.
[0046] Specifically, in order to improve the dredging effect of the material, the dredging structure 2 includes a rotating rod 21 and a dredging member 22, wherein the dredging member 22 is always located inside the material chamber. When a blockage occurs in the material chamber and needs to be dredged, the length of the rotating rod 21 extending into the material chamber can be adjusted by rotating the rotating rod 21 to dredge different positions in the material chamber. In this embodiment, the dredging member 22 can be a stirring paddle protruding from the outer periphery of the rotating rod 21, or a rotating reamer 221, etc., as long as it can disperse the bulk material into powdery material.
[0047] In one embodiment, the clearing member 22 is easily damaged after long-term use. In order to facilitate replacement, the clearing member 22 is detachably connected to the rotating rod 21, for example, it can be a snap connection, a threaded connection or a plug-in connection, as long as the connection method is easy to disassemble and install.
[0048] In one embodiment, see Figure 4 , the rotary reamer 221 comprises:
[0049] The blade shaft 2211 is connected to the dredging end 211; and
[0050] The plurality of blade teeth 2212 are evenly spaced apart along the outer circumference of the blade shaft 2211 .
[0051] Specifically, when encountering a blockage of strong clumped materials, a sharp clearing piece 22 is required to crush them. The rotary reamer 221 in this embodiment includes a knife shaft 2211 and a plurality of knife teeth 2212 arranged at intervals along the outer circumference of the knife shaft 2211, so that the knife teeth 2212 can cut and crush the large pieces of blocked materials under the drive of the knife shaft 2211, thereby improving the clearing efficiency.
[0052] In one embodiment, see Figure 4 The blade teeth 2212 are inclined to the blade shaft 2211, and the angle between the blade teeth 2212 and the outer peripheral surface of the blade shaft 2211 is in the range of 20°-80°. In this way, the blade teeth 2212 and the blade shaft 2211 are inclined, and the two have a certain inclination angle, which is conducive to crushing materials; and the dredging member 22 has a simple structure, low manufacturing cost, large cutting depth, and high cutting efficiency.
[0053] In one embodiment, see Figure 1 The chute body 1 is provided with a relative feed port 11 and a discharge port 12, both of which are connected to the material cavity, and the aperture of the chute body 1 decreases from the feed port 11 to the discharge port 12. In this way, the material in the material cavity can fall freely along the side wall of the chute body 1 under the action of its own gravity, without the need for other additional driving force, which can effectively improve the discharge efficiency of the discharger.
[0054] In one embodiment, see Figure 1 The discharge chute 100 further includes a pneumatic conveying member 3, which is disposed below the chute body 1 and is connected to the discharge port 12. In order to timely discharge the material in the material cavity, a pneumatic conveying member 3 can also be connected below the discharge port 12 to continuously transfer the material to other locations to prevent the material accumulated in the material cavity from overflowing. Of course, in other embodiments, a conveying device such as a screw conveyor can also be connected to the discharge port 12 for conveying materials.
[0055] In one embodiment, see Figure 1 Considering that there may be multiple blocked positions in the material cavity and the height requirement of the chute body 1 itself, in order to dredge each blocked position and achieve full-range dredging in the material cavity, multiple dredging structures 2 are provided at intervals along the first direction. The first direction referred to in this embodiment is the direction from the feed port 11 to the discharge port 12. Of course, multiple dredging structures 2 can also be provided at intervals on the inner peripheral surface of the chute body 1; when multiple dredging structures 2 are provided, in order to avoid interference between the multiple dredging structures 2, when one of the blocked positions is dredged, it is rotated in the opposite direction, extending as much as possible outside the chute body 1, and retaining a shorter length in the material cavity, so as to avoid affecting the activities of other dredging structures 2 in the material cavity.
[0056] In one embodiment, see Figure 2 and Figure 3 The unloading chute 100 also includes a handle 23, which is fixed at the rotating end 212 and is used to drive the rotation of the rotating rod 21; a handle 23 can be provided at the end of the rotating rod 21 extending outside the chute body 1. The setting of the handle 23 is conducive to the user holding the rotating rod 21 and rotating it in the desired direction, thereby completing the dredging of the material.
[0057] In one embodiment, see Figure 1 In consideration of the need to facilitate transportation, the chute body 1 is configured in a conical shape, and the side wall of the chute body 1 is configured at an angle. Accordingly, the rotating rod 21 is configured to be inclined on the chute body 1. According to the inclination of the side wall of the chute body 1, the rotating rod 21 can be installed at an appropriate inclination angle. For example, the angle between the rotating rod 21 and the axis of the chute body 1 is 50°-90°, and the specific degree can be adjusted according to the actual situation on site.
[0058] In one embodiment, see Figure 3 The rotating rod 21 is a screw rod, which is threadedly connected to the chute body 1, and the external thread of the screw rod is a trapezoidal thread. The trapezoidal thread can withstand larger axial force and radial force. When there is a large amount of powder in the material chamber, the trapezoidal thread and the chute body 1 still have excellent self-locking properties. Under the gravity of a large amount of powder, the screw rod is not easy to loosen, nor will it be bent, maintaining an excellent anti-blocking function.
[0059] In one embodiment, see Figure 3 and Figure 4 The unloading chute 100 further includes a locking member 24, which is sleeved on the outer periphery of the rotating rod 21 and is threadedly connected to the rotating rod 21. The rotating rod 21 can be locked and fixed on the chute body 1 through the threaded connection between the locking member 24 and the rotating rod 21, so that the dredging member 22 remains in a fixed position, so that subsequent large pieces of agglomerated materials can be crushed when they fall to the position of the dredging member 22, so as to avoid continued falling and blockage under the chute body 1. The locking member 24 in this embodiment can be a locking nut, or a screw-on flange, etc., as long as it can play the role of locking the rotating rod 21.
[0060] The utility model also proposes a discharger, which includes the discharge chute 100 described in any of the above embodiments. The specific structure of the discharge chute 100 refers to the above embodiments. Since the present discharger adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. It should be noted that the discharger can be a star-shaped discharger or other dischargers containing the above discharge chute 100.
[0061] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
