Description

Technical Field

[0001] This utility model relates to the field of hoppers, and more particularly to a hopper with a bridge-breaking mechanism. Background Technology

[0002] In the calcite preparation process, after the ore is crushed and ground, it forms very fine powder (such as heavy calcium carbonate powder). When these fine powder materials are stored in hoppers or silos, they are very prone to "bridging".

[0003] To address the bridging problem, existing technologies include a powder agglomeration breaker, such as Chinese Patent Publication No. CN220949500U. This utility model includes a breaker body, a connecting pipe, and an air outlet pipe, as well as a stirring component. The stirring component includes a mounting frame, an impeller, a connecting rod, a reciprocating rod, a swing rod, and a rotating component. The mounting frame is fixedly connected to the air outlet pipe, the impeller is rotatably connected to the mounting frame, the connecting rod is rotatably connected to the impeller, the reciprocating rod is rotatably connected to the connecting rod, and the swing rod is rotatably connected to the reciprocating rod. When gas is ejected from the air outlet pipe, it blows the impeller to rotate, causing the impeller to drive the connecting rod to move. The connecting rod drives the reciprocating rod to move up and down, which in turn drives the swing rod to move up and down, thereby stirring the agglomerated and accumulated powder. Combined with the air ejected from the air outlet pipe, this enhances the bridging effect, thus achieving the goal of improving the bridging effect.

[0004] Existing technologies similar to the aforementioned patent have the following problems: maintenance of the bridge breaking mechanism requires disassembling a large number of parts, which is cumbersome, and the swing rod is only set on one side inside the hopper, creating a dead angle.

[0005] Therefore, there is an urgent need for a hopper with a bridge-breaking mechanism that can solve the above-mentioned technical problems. Utility Model Content

[0006] To address the problems of inconvenient maintenance and blind spots in existing bridge-breaking mechanisms, this utility model proposes a hopper with an integrated bridge-breaking mechanism, the technical solution of which is as follows:

[0007] A hopper with a bridge-breaking mechanism includes a hopper body vertically mounted on the ground by a support, and includes: a first mounting port and a second mounting port symmetrical about its axis are opened on the side wall near the lower end of the hopper body;

[0008] It also includes a bridge-breaking roller horizontally disposed inside the hopper body, a drive end block rotatably sleeved on the first end of the bridge-breaking roller, and a rotatable support seat detachably installed at the first mounting port; the end of the drive end block away from the inner side of the hopper body extends radially outward to form a drive end flange, and a limit protrusion is provided on the bridge-breaking roller to axially position the drive end block.

[0009] The second end of the bridge-breaking roller can be coaxially inserted into and supported in the rotating support seat, so that the drive end flange of the drive end block can be detachably attached to the outside of the second mounting port, and the bridge-breaking roller passes through the drive end block and is detachably connected to the output end of the drive device.

[0010] Furthermore, the edges of the first mounting port and the second mounting port protrude outwards from the outside of the hopper body to form a first tubular boss and a second tubular boss, respectively, and the first tubular boss and the second tubular boss are coaxial.

[0011] Furthermore, both the first tubular boss and the second tubular boss have several threaded holes parallel to their own axes at the ends away from the inner side of the hopper body.

[0012] Furthermore, the rotating support is a column, and a first guide key is provided on the outer wall of the rotating support. A first keyway is provided on the inner wall of the first tubular boss. The rotating support can be slidably inserted into the first tubular boss on the same axis. The first guide key and the first keyway cooperate to lock the rotating support in the entire circumference. The end of the rotating support away from the inside of the hopper body protrudes radially to form a support end flange. The support end flange and the first tubular boss are detachably fixed by bolts.

[0013] Furthermore, the rotating support seat has a rotating hole at one end facing the hopper body, and a bearing a is coaxially arranged in the rotating hole. A rotating inner cylinder is arranged in the bearing a, and a sealing mechanism is provided between the rotating inner cylinder and the rotating hole. The rotating inner cylinder has an insertion hole coaxially arranged on one side facing the inside of the hopper body. The insertion hole is an irregularly shaped hole. The second end of the bridge breaking roller is configured to match the shape of the irregularly shaped hole and can be coaxially inserted into the irregularly shaped hole. The bridge breaking roller can drive the rotating inner cylinder to rotate.

[0014] Furthermore, the drive end block is a column, and a second guide key is provided on the outer wall of the drive end block. A second keyway is provided on the inner wall of the second tubular boss. The drive end block can be coaxially slidably inserted into the second tubular boss. The second guide key and the second keyway cooperate to lock the entire drive end block circumferentially. After installation, the drive end flange is attached to the end of the second tubular boss away from the hopper body and is fixed to each other by bolts.

[0015] Furthermore, the drive end block has a mounting hole at one end facing the hopper body, a bearing b is coaxially arranged in the mounting hole, the bridge breaking roller is coaxially arranged in the bearing b, and a sealing mechanism is provided between the bridge breaking roller and the wall of the mounting hole. The bridge breaking roller extends through the drive end block to the outside of the hopper body, and the end of the bridge breaking roller located on the outside of the hopper body is connected to the output shaft of the drive device through a magnetic coupling.

[0016] Furthermore, the inner sidewall of the hopper body is provided with several jetting mechanisms.

[0017] The beneficial effects of this utility model are as follows: The symmetrically arranged first and second mounting ports, combined with a detachable rotating support and a drive end block with a drive end flange, enable quick disassembly and independent maintenance of the bridge-breaking roller without entering the hopper body or removing other components; the circumferential locking structure (first and second guide keys, first and second guide grooves) using irregularly shaped insertion holes and keyways ensures transmission stability and avoids maintenance dead zones; the application of a magnetic coupling further improves transmission sealing and safety; and the air jet mechanism on the inner wall of the hopper body effectively prevents material adhesion and bridging, significantly improving maintenance efficiency and unblocking reliability.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] like Figure 1 As shown, a hopper with a bridge-breaking mechanism includes a hopper body 1 vertically mounted on the ground by a support, and includes a first mounting port 2 and a second mounting port 3 symmetrical about its axis on the side wall near the lower end of the hopper body 1.

[0024] like Figure 1 , Figure 2 , Figure 3As shown, it also includes a bridge-breaking roller 4 horizontally disposed inside the hopper body 1, a drive end block 7 rotatably sleeved on the first end of the bridge-breaking roller 4, and a rotatable support seat 10 detachably installed in the first mounting port 2; the radial outer edge of the drive end block 7 is fixed with a drive end flange 8, and the bridge-breaking roller 4 is provided with a limit protrusion 6 to axially position the drive end block 7.

[0025] like Figure 1 , Figure 2 As shown, the second end of the bridge breaking roller 4 can be coaxially inserted into and supported in the rotating support seat 10, so that the drive end flange 8 can be detachably attached to the outside of the second mounting port 3, and the bridge breaking roller 4 can be detachably connected to the output end of the drive device through the drive end block 7.

[0026] like Figure 1 , Figure 2 , Figure 3 As shown, preferably, the edges of the first mounting port 2 and the second mounting port 3 protrude outwards from the hopper body 1 to form a first tubular boss 11 and a second tubular boss 12, respectively, and the first tubular boss 11 and the second tubular boss 12 are coaxial. The technical advantage of this preferred solution is that by setting coaxial tubular bosses, the installation alignment accuracy of the rotary support 10 and the drive end block 7 is significantly improved, while facilitating rapid positioning during assembly.

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, preferably, the ends of the first tubular boss 11 and the second tubular boss 12 furthest from the inner side of the hopper body 1 are each uniformly provided with a plurality of threaded holes 13 parallel to their own axes around their own axes. The technical advantage of this preferred solution is that the equiangular distribution of the threaded holes 13 allows the rotary support 10 and the drive end block 7 to be uniformly fastened with bolts, effectively avoiding excessive local stress, ensuring the sealing performance of the connecting flange, and simplifying the disassembly and installation process.

[0028] like Figure 1 , Figure 2As shown, preferably, the rotary support 10 is a column, and a first guide key 14 is provided on the outer wall of the rotary support 10. A first keyway 15 is provided on the inner wall of the first tubular boss 11. The rotary support 10 can be coaxially slidably inserted into the first tubular boss 11. The first guide key 14 and the first keyway 15 cooperate to radially lock the rotary support 10 as a whole. A support end flange 9 is fixed to the outer periphery of the end of the rotary support 10 away from the interior of the hopper body 1. A first fixing through hole 16 is opened on the support end flange corresponding to the threaded hole 13. Bolts can be passed through the first fixing through hole 16 and the threaded hole 13. The support end flange 9 and the first tubular boss 11 are detachably fixed by bolts. The technical effect of this preferred solution is that the cooperation of the guide key and the keyway realizes the rapid radial positioning and circumferential constraint of the rotary support 10, preventing its rotation. At the same time, the flange and bolts achieve axial fixation, which greatly improves the installation accuracy and operation convenience.

[0029] like Figure 1 , Figure 2 As shown, preferably, the rotating support 10 has a rotating hole 17 at one end facing the hopper body 1. A bearing a181 is coaxially arranged inside the rotating hole 17, and a rotating inner cylinder 19 is arranged inside the bearing a181. A sealing mechanism is provided between the rotating inner cylinder 19 and the rotating hole 17 (rotational sealing of the shaft is a part of the prior art, such as oil seals and mechanical seals, which will not be elaborated here). The rotating inner cylinder 19 has an insertion hole 20 coaxially arranged on one side facing the inside of the hopper body 1. The insertion hole 20 is an irregularly shaped hole. The second end of the bridge-breaking roller 4 is designed to match the shape of the irregularly shaped hole and can be coaxially inserted into the irregularly shaped hole. The bridge-breaking roller 4 can drive the rotating inner cylinder 19 to rotate. The technical effect of this structure is that the irregularly shaped hole enables quick insertion and torque transmission between the bridge-breaking roller 4 and the rotating inner cylinder 19. The bearing a181 structure effectively reduces rotational friction resistance, and the sealing mechanism prevents powder from entering the bearing a181, significantly improving transmission reliability and service life.

[0030] like Figure 1 , Figure 2As shown, preferably, the drive end block 7 is a column, and a second guide key 21 is provided on the outer wall of the drive end block 7. A second keyway 22 is provided on the inner wall of the second tubular boss 12. The drive end block 7 can be coaxially slidably inserted into the second tubular boss 12. The second guide key 21 and the second keyway 22 cooperate to radially lock the entire drive end block 7. After installation, the drive end flange 8 fits against the end of the second tubular boss 12 away from the hopper body 1. A second fixing through hole 23 is opened on the drive end flange 8 corresponding to the threaded hole 13. Bolts can be passed through the second fixing through hole 23 and the threaded hole 13. The drive end flange 8 and the first tubular boss 11 are detachably fixed by bolts. The technical effect of this structure is that the cooperation of the guide key and the keyway ensures the rapid installation and circumferential positioning of the drive end block 7. Combined with the bolt fastening of the drive end flange 8, high-precision centering and reliable sealing on the drive side are achieved, effectively preventing material leakage.

[0031] like Figure 1 , Figure 3 As shown, preferably, the drive end block 7 has a mounting hole 24 at one end facing the hopper body 1. A bearing b182 is coaxially arranged in the mounting hole 24, and the bridge-breaking roller 4 is coaxially arranged in the bearing b182. A sealing mechanism is provided between the bridge-breaking roller 4 and the wall of the mounting hole 24 (rotary sealing of the shaft is a part of the prior art, such as oil seals and mechanical seals, which will not be elaborated here). The bridge-breaking roller 4 extends through the drive end block 7 to the outside of the hopper body 1, and the end of the bridge-breaking roller 4 located on the outside of the hopper body 1 is connected to the output shaft of the drive device by a sealing mechanism. The magnetic coupling 25 provides the transmission connection. It should be noted that the driving device is a geared motor 26 (the reducer and motor are integrated). The driven end of the magnetic coupling 25 is coaxially fixed to the end of the bridge-breaking roller 4, and the driving end is fixed to the output shaft of the geared motor 26. The geared motor 26 is detachably mounted in a designated position (a position that can effectively transmit torque) via another bracket. If maintenance of the bridge-breaking roller 4 is required, the geared motor 26 needs to be moved to avoid affecting disassembly, or the geared motor 26 can be mounted on a fixed movable device for easy relocation. The technical advantages of this preferred solution are: the magnetic coupling 25 achieves non-contact torque transmission, facilitating the assembly and disassembly of the bridge-breaking roller 4; the movable installation of the geared motor 26 greatly facilitates maintenance operations, shortens downtime, and improves equipment maintainability.

[0032] like Figure 1As shown, preferably, the inner sidewall of the hopper body 1 is provided with several jetting mechanisms that intermittently jet air into the hopper body 1. Each jetting mechanism is a jet nozzle 27 that penetrates the hopper wall and is angled downwards to prevent direct contact with the powdery raw material. The gas source for the jet nozzles 27 is an external air source connected through an air pipe 28. The jet nozzles 27 intermittently blow air onto the powdery raw material against the hopper wall, preventing the powdery raw material from sticking to the hopper wall. The technical advantage of this preferred solution is that intermittent jetting effectively disrupts the adhesion and accumulation of powder on the inner wall of the hopper body 1, avoiding the formation of "bridging" or "rat holes." The angled downward arrangement prevents the airflow from directly impacting the material, thus avoiding breakage or dust generation and ensuring the stability and uniformity of material flow.

[0033] like Figure 1 As shown, it should also be noted that the bridge breaking roller 4 is provided with radial branches 5 to enhance the bridge breaking effect. The length of the radial branches 5 does not affect the removal of the bridge breaking roller 4 from the second mounting port 3.

[0034] The method of using this utility model is as follows: During installation, firstly, the rotating support 10 is inserted and fixed by aligning its first guide key 14 with the first keyway 15 of the first tubular boss 11. Then, the drive end block 7 is installed and fixed by aligning its second guide key 21 with the second keyway 22 of the second tubular boss 12. The end of the bridge-breaking roller 4 with the limit protrusion 6 is inserted from the drive end, and its second end irregular shaft head is inserted into the irregular insertion hole 20 of the rotating support 10 to achieve support and transmission connection. Finally, the reduction motor 26 is moved to the working position and connected to the end of the bridge-breaking roller 4 through the magnetic coupling 25. During operation, the reduction motor 26 drives the bridge-breaking roller 4 to rotate through the magnetic coupling 25, and at the same time, the air nozzle 27 on the side wall of the hopper body 1 sprays air intermittently to jointly destroy the bridging phenomenon of the material. During maintenance, simply remove the reduction motor 26 and remove the bolts of the drive end flange 8 to pull the bridge-breaking roller 4 out from the drive side as a whole. The operation is simple.

[0035] It should be noted that the support frame is not shown in the attached diagram, and the structure of the hopper has been simplified.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions 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 solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
