Description

Technical Field

[0001] This utility model relates to the field of material feeding valve technology, and in particular to a dual-mode dust removal material feeding valve with wear-resistant lining. Background Technology

[0002] In industrial production, the efficient and stable operation of dust control and material conveying systems is crucial for ensuring production efficiency and environmental quality. However, traditional dust collection and feeding valves often face problems such as material wear, reduced sealing performance, and low unloading efficiency after long-term operation. To solve these problems, a dual-mode dust collection and feeding valve with wear-resistant liners has emerged.

[0003] A feeding valve device with announcement number CN208565771U has a structure including a bolt connection port, a feeding port, a first discharge port, a second discharge port, a motor, a housing, a fixing ring, bolts, a heat dissipation port, and an adjustment device. The feeding port and the first discharge port are integrated. The bolts are installed above the heat dissipation port. The adjustment device includes a handle, a connecting rod, a push bar, a gear, a bearing, a limit block, a push rod, a push rod, a control rod, and a torsion spring. The handle and the connecting rod are integrated. The connecting rod and the gear are welded together. This feeding valve device has an adjustment device in its structure. By driving the connecting rod with the handle, the welded gear rotates, which drives the push bar that meshes with it to move forward. This drives the push rod and the push rod to move downward. The push rod is welded to the control rod, thereby driving the control rod to slowly open and control the feeding flow. When feeding is finished and the adjustment device needs to be closed, the handle is rotated back and the control rod is reset by the torsion spring.

[0004] The existing technology described above has a single function and lacks material pretreatment, meaning it cannot filter materials. Unfiltered materials may contain large particles, clumps, or foreign objects. These substances can easily clog the valve passage when passing through the feeding valve, preventing the material from flowing normally and affecting production efficiency. Furthermore, large particles can cause wear on the valve's inner wall and sealing components when passing through the valve, which will shorten the valve's service life and increase maintenance costs over time. Therefore, corresponding improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to provide a dual-mode dust collection and feeding valve with wear-resistant lining plate to solve the problem mentioned in the background art that the existing dust collection and feeding valves have a single function and lack material pretreatment, which leads to easy damage to the valve body.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dual-mode dust removal and feeding valve with wear-resistant lining plate, comprising a dust removal and feeding valve body, a connecting plate, and a discharge pipe. The top of the dust removal and feeding valve body is connected to the connecting plate, and the connecting plate is evenly provided with mounting holes. The discharge pipe is connected to one side of the dust removal and feeding valve body.

[0007] One end of the discharge pipe is fixed with a connecting flange, and the connecting flange is evenly provided with circular fixing holes. A sealing groove is provided on one side of the connecting flange. An adjustment mechanism is provided on the outside of the dust removal discharge valve body. A ceramic liner is welded on the inner wall of the dust removal discharge valve body. A filter assembly is provided at the top inside the dust removal discharge valve body.

[0008] Preferably, the filter assembly includes an intercepting net disposed at the inlet position inside the dust removal and feeding valve body, and fixing mechanisms are provided on both sides of the bottom end of the intercepting net.

[0009] Preferably, the fixing mechanism includes a docking block disposed on the inner wall of the dust removal and feeding valve body, and the docking block is provided with a docking hole inside. A fastening ring plate is connected inside the docking hole, and a fixing block is snapped into the fastening ring plate. The fixing block is provided with a movable hole, and the fixing block is fixed to the bottom end of the interception net.

[0010] Preferably, auxiliary protrusions are fixed on both sides of the inner side of the fastening ring plate, and the auxiliary protrusions are all made of rubber. The fixing block has recesses on both sides, and the auxiliary protrusions are inserted into the recesses on the fixing block.

[0011] Preferably, an adjusting plate is movably connected to one side of the dust removal and feeding valve body, and the adjusting plate blocks the opening of the discharge pipe.

[0012] Preferably, the adjusting mechanism includes a housing, which is located outside the main body of the dust removal and feeding valve. A micro motor is connected to one side of the housing, and a worm is fixed to the output shaft end of the micro motor. A worm wheel is engaged on one side of the worm, and a drive shaft passes through the inside of the worm wheel.

[0013] Preferably, one end of the drive shaft extends into the interior of the dust removal and feeding valve body, and the drive shaft passes through the adjusting plate so that the adjusting plate is sleeved on the drive shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the dual-mode dust removal and feeding valve with wear-resistant lining not only has the effect of removing impurities from the material and preventing material impurities from wearing the valve body, but also can perform multiple feeding modes to meet different usage needs;

[0015] During the feeding process, the intercepting net is used to filter and intercept the falling material to remove impurities and prevent these impurities from damaging or clogging the internal structure of the dust removal feeding valve. Pulling the intercepting net causes the auxiliary protrusion to disengage from the notch on the fixing block until the fixing block disengages from the fastening ring plate, at which point the intercepting net can be removed from the dust removal feeding valve body for later cleaning and maintenance.

[0016] By using ceramic liners, the wear resistance of the dust collector discharge valve body is enhanced, so that the material can directly contact the ceramic liner during the discharge process, effectively preventing damage to the dust collector discharge valve body from wear.

[0017] A micro motor is used to rotate the worm gear, which meshes with the worm wheel, causing the worm wheel, drive shaft, and adjusting plate to rotate. This allows for adjustment of the adjusting plate's operating angle, enabling partial or complete blocking of the discharge pipe's outlet. This ensures continuous and stable material discharge, or allows for intermittent or low-flow material discharge, thus meeting more refined production needs and improving material discharge efficiency.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Please see Figures 1-6 The present invention provides the following technical solution: Example 1

[0028] To address the issue of inconvenient material discharge adjustment in existing dust collector discharge valves, the following technical solution is proposed. Please refer to the following for details. Figure 1 , Figure 2 , Figure 3 , Figure 5 A dual-mode dust collection and feeding valve with wear-resistant lining includes a dust collection and feeding valve body 1, a connecting plate 2, and a discharge pipe 3. The connecting plate 2 is connected to the top of the dust collection and feeding valve body 1, and the connecting plate 2 has uniformly arranged mounting holes 201. The discharge pipe 3 is connected to one side of the dust collection and feeding valve body 1. An adjusting plate 9 is movably connected to one side inside the dust collection and feeding valve body 1, and the adjusting plate 9 blocks the opening of the discharge pipe 3. A connecting flange 4 is fixed to one end of the discharge pipe 3, and the connecting flange 4 has uniformly arranged circular fixing holes 401. A mounting hole 401 is provided on one side of the connecting flange 4. The sealing groove 402 and the dust removal and feeding valve body 1 are provided with an adjustment mechanism 5. The adjustment mechanism 5 includes a housing 502, which is located on the outside of the dust removal and feeding valve body 1. A micro motor 503 is connected to one side of the housing 502, and a worm 504 is fixed to the output shaft end of the micro motor 503. A worm wheel 505 is meshed on one side of the worm 504, and a drive shaft 501 passes through the inside of the worm wheel 505. One end of the drive shaft 501 extends into the inside of the dust removal and feeding valve body 1. The drive shaft 501 passes through the adjustment plate 9, so that the adjustment plate 9 is sleeved on the drive shaft 501.

[0029] In this embodiment, by using the mounting hole 201 and the connecting plate 2, the top of the dust removal and feeding valve body 1 is connected to the external feed pipe, allowing materials to fall into the dust removal and feeding valve body 1 and be discharged from the discharge pipe 3. During this process, the adjusting plate 9 is used to block the feed inlet of the discharge pipe 3 with different areas to achieve dual-mode discharge. Specifically, the micro motor 503 drives the worm 504 to rotate, and the worm 504 meshes with the worm wheel 505, which in turn causes the worm wheel 505 and the drive shaft 501 to rotate, thus causing the adjusting plate 9 to swing left and right. When the adjusting plate 9 is fully rotated to the left, the feed inlet is fully exposed, achieving continuous discharge. When the adjusting plate 9 is rotated to the corresponding position on the right, the feed inlet area is adjusted to achieve intermittent small-flow discharge, thereby achieving dual-mode discharge to improve discharge accuracy and efficiency. Example 2

[0030] This embodiment differs from Embodiment 1 in that it utilizes the interceptor net 7 to achieve material filtration and impurity removal during the discharge process. Therefore, the following technical solution is disclosed. Please refer to the following for details. Figure 2 , Figure 4 , Figure 6 A ceramic liner 6 is welded to the inner wall of the dust removal and feeding valve body 1. A filter assembly is provided at the top of the dust removal and feeding valve body 1. The filter assembly includes an intercepting net 7 located at the inlet of the dust removal and feeding valve body 1. Fixing mechanisms 8 are provided on both sides of the bottom of the intercepting net 7. The fixing mechanism 8 includes a docking block 801 located on the inner wall of the dust removal and feeding valve body 1. A docking hole 802 is provided inside the docking hole 802. A fastening ring plate 803 is connected inside the docking hole 802. A fixing block 804 is snapped inside the fastening ring plate 803. A movable hole 805 is provided on the fixing block 804. The fixing block 804 is fixed to the bottom of the intercepting net 7. Auxiliary protrusions 806 are fixed on both sides of the fastening ring plate 803. The auxiliary protrusions 806 are all made of rubber. Recesses are provided on both sides of the fixing block 804. The auxiliary protrusions 806 are snapped into the recesses on the fixing block 804.

[0031] In this embodiment, the fixing block 804 is positioned corresponding to the docking block 801. The fixing block 804 is inserted into the fastening ring plate 803 in the docking hole 802, and the fastening ring plate 803 holds the fixing block 804 in place, thus fixing it. The auxiliary protrusion 806 is then inserted into the recesses on both sides of the fixing block 804 to enhance the firmness of the fixing block 804. Then, the intercepting net 7 is installed in the dust removal and feeding valve body 1. During the material discharge process, the intercepting net 7 is used to filter the material to achieve the effect of removing impurities and prevent impurities in the material from abrading the inner wall of the dust removal and feeding valve body 1. A ceramic liner 6 is set in the dust removal and feeding valve body 1. The high strength and wear resistance of the ceramic liner 6 can enhance the wear resistance of the dust removal and feeding valve body 1 and prevent damage to the dust removal and feeding valve body 1.
