Description

Technical Field

[0001] This invention relates to the technical field of the papermaking industry, specifically to a funnel for feeding high polymers in the form of chemical auxiliary powders. Background Technology

[0002] The polymer feeding funnel is a device related to the preparation of chemical auxiliary powders. It mainly uses a spiral to transport the powdered chemical auxiliary materials to the funnel, and then connects to a blower and pipeline to achieve the blowing effect of the powdered chemical auxiliary materials.

[0003] When in use, the polymer feeding funnel uses a blower and connecting pipes to transport water and powder to a dispersion head where they are mixed in a certain proportion, preparing a liquid with the required concentration to ensure stable concentration, thus stabilizing the production process and quality.

[0004] In existing technologies, due to the small space between the polymer feeding spiral inlet and the hopper connected to the pneumatic conveying pipe, the straight feeding inlet is generally fixed with flanges and bolts. This not only leads to poor sealing and easy powder leakage, but also affects the environment and the observation and disassembly efficiency of subsequent operators. Therefore, in order to address the above problems, a funnel for feeding polymers in the preparation of chemical auxiliary powder is proposed. Summary of the Invention

[0005] To address the shortcomings of existing technologies and the problems associated with straight-through discharge ports that typically use flanges and bolts for fastening, which can lead to poor sealing and powder leakage, environmental impact, and reduced efficiency for subsequent operators in observation and disassembly, this invention proposes a funnel for discharging high polymers used in the preparation of chemical auxiliary powders.

[0006] A funnel for feeding polymers in the preparation of chemical auxiliary powders includes a conveying pipe, a feed pipe, a buckle, a top cover, a receiving hopper, and a filter screen. The bottom of the receiving hopper is connected to a connecting pipe, and the top cover is snapped onto the top of the receiving hopper. The conveying pipe is connected to the feed pipe, and the conveying pipe and the feed pipe are fixedly connected by the buckle. The bottom of the feed pipe extends through the receiving hopper, and the bottom end of the feed pipe extends through the top cover. Internal threads are formed on the inner sides of the openings at both ends of the connecting pipe. The receiving hopper has a conical structure, and the filter screen is disposed inside the receiving hopper. To prevent agglomerated powder from falling into the connecting pipe and causing blockage, the filter screen disposed inside the receiving hopper intercepts the agglomerated powder, thereby preventing blockage and facilitating powder processing.

[0007] Preferably, a locking block is provided at the end of the connection between the conveying pipe and the feed pipe, and the buckle is engaged on the outside of the locking block at the connection between adjacent conveying pipes and feed pipes. Therefore, when the feed pipe and the conveying pipe are connected by the buckle, the sealing between the conveying pipe and the feed pipe can be increased by arranging a rubber strip on the inside of the buckle, which helps to prevent powder leakage.

[0008] Preferably, the buckle consists of two sets of semi-circular clips with the same structure, and a connecting shaft is perforated at one connection point of the two sets of semi-circular clips; a torsion spring is sleeved on the connecting shaft; the other ends of the two sets of semi-circular clips are fixed by bolts, so that the two sets of semi-circular clips with the same structure can be clamped at the top of the feed pipe and the bottom of the conveying pipe, and in conjunction with the rubber strip set on the inner side of the semi-circular clips, the sealing between the conveying pipe and the feed pipe can be increased, effectively reducing powder leakage.

[0009] Preferably, the top cover is provided with a material feeding assembly, which consists of a top plate, a connecting rod, an elastic band, a connecting plate, an elastic plate, and a first spring. The elastic band is fixed to the bottom of the top cover, and the connecting plate is fixed to the bottom of the elastic band. The elastic plate is circumferentially connected to the bottom of the connecting plate. The connecting rod passes through the top cover, and the top plate is fixed to the top of the connecting rod. The bottom of the connecting rod is located inside the receiving hopper. The first spring is sleeved on the end of the connecting rod located inside the receiving hopper. Therefore, the agglomerated powder is separated into several small powder particles, which eventually pass through the filter screen and enter the connecting pipe at the bottom. This avoids the powder particles from being trapped on the filter screen due to their large size. Long-term operation may cause the filter screen to become clogged. The intermittent movement of the material feeding assembly can prevent the filter screen from becoming clogged.

[0010] Preferably, a fixing block is fixedly connected to the top cover, and the fixing block is arranged at the position where the connecting rod passes through the top cover; a brush bristle is fixedly connected to the inner side of the fixing block, and the brush bristle contacts the side wall of the connecting rod. The brush bristle set on the inner side of the fixing block can seal the connection rod and the top cover to prevent powder leakage. At the same time, the brush bristle can clean the connecting rod to prevent the powder attached to the connecting rod from leaking out, which is beneficial to protecting the surrounding air quality.

[0011] Preferably, the elastic plate has an L-shaped structure; the bottom of the connecting plate has a central groove corresponding to the feed pipe, and the elastic plate is fixed to the outside of the central groove. At the same time, it has a certain buffering effect, which can achieve the effect of sorting agglomerated powder.

[0012] Preferably, the material feeding assembly is arranged at the upper end of the filter screen, and both the filter screen and the material feeding assembly are arranged inside the receiving hopper.

[0013] Preferably, the top plate has an annular structure, and the feed pipe passes through the middle of the top plate. Therefore, when the annular top plate is pressed manually, the connecting rod can be used to indirectly drive the bottom connecting plate to move in the receiving hopper, thereby achieving the function of unloading agglomerated powder.

[0014] The advantages of this invention are:

[0015] 1. This invention replaces the original straight-through discharge port, which is fixed by flanges and bolts, with a straight-through discharge port that uses a locking block, a buckle, and bolts, making disassembly and assembly convenient. At the same time, the connection between the locking block and the buckle is tight, avoiding powder leakage caused by poor sealing.

[0016] 2. This invention changes the original welded top cover to a top cover that can move up and down. During normal processing, the top cover can be manually separated from the receiving hopper, which facilitates normal observation of the screw powder discharge during production and avoids the inability to deal with abnormalities in time.

[0017] 3. By setting a filter screen inside the receiving hopper and changing the receiving hopper to a conical structure, the present invention can effectively intercept agglomerated materials when they fall into the receiving hopper through the feed pipe. Furthermore, the material loosening component can loosen the agglomerated materials to a certain extent, thereby avoiding pipe blockage and unstable concentration preparation.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-6 As shown, a funnel for discharging polymers for preparing chemical auxiliary powder includes a conveying pipe 5, a feed pipe 3, a buckle 4, a top cover 2, a receiving hopper 1, and a filter screen 6. The bottom of the receiving hopper 1 is connected to a connecting pipe 11, and the top cover 2 is snapped onto the top of the receiving hopper 1. The conveying pipe 5 is connected to the feed pipe 3, and the conveying pipe 5 and the feed pipe 3 are fixedly connected by the buckle 4. The bottom of the feed pipe 3 extends through the receiving hopper 1, and the bottom end of the feed pipe 3 extends through the top cover 2. The two ends of the connecting pipe 11 have internal threads 12 on their inner sides. The receiving hopper 1 has a conical structure, and the filter screen 6 is disposed inside the receiving hopper 1.

[0028] Specifically, traditional polymer feeding funnels are generally straight-through pipe feeding ports. However, due to the lack of practicality of straight-through pipe feeding ports, problems such as powder leakage, inability to detect abnormalities, and blockage of pipes by agglomerated materials occur during actual production processes, which further affect the preparation of chemical auxiliary powders.

[0029] This device replaces the original straight-through discharge port with a conical receiving hopper 1. Therefore, when powder is spirally fed from the conveying pipe 5 and discharged into the receiving hopper 1 through the feed pipe 3, the sealing between the feed pipe 3 and the conveying pipe 5 is improved because they are fixed together by a snap-fit ​​4. Furthermore, because a rubber strip is installed at the connection between the feed pipe 3 and the receiving hopper 1, excessive powder leakage is prevented as the powder moves into the receiving hopper 1. After the powder enters the receiving hopper 1, the top cover 2 can be manually moved up and down to observe the powder flow. The spiral powder feeding mechanism inside the hopper 1 facilitates timely handling of any abnormalities, preventing greater losses. To prevent lumpy powder from falling into the connecting pipe 11 and causing blockage, a filter screen 6 inside the receiving hopper 1 intercepts the lumpy powder, thus avoiding blockage and facilitating powder processing. Internal threads 12 are provided on the inner sides of both ends of the connecting pipe 11 for connecting the air ducts at both ends, facilitating disassembly and maintenance. The removable top cover 2 allows for observation and cleaning of the receiving hopper 1 during operation.

[0030] In one embodiment of the present invention, a locking block is provided at the end of the connection between the conveying pipe 5 and the feeding pipe 3, and the buckle 4 is engaged with the outside of the locking block at the connection between the adjacent conveying pipe 5 and the feeding pipe 3.

[0031] Specifically, a locking block is provided at the end of the connection between the conveying pipe 5 and the feed pipe 3. Therefore, when the feed pipe 3 and the conveying pipe 5 are connected by the buckle 4, the sealing between the conveying pipe 5 and the feed pipe 3 can be increased by arranging a rubber strip on the inside of the buckle 4, which helps to prevent the leakage of powder.

[0032] In one embodiment of the present invention, the buckle 4 is composed of two sets of semi-circular clips with the same structure, and a connecting shaft 41 is perforated and connected to one of the connecting ends of the two sets of semi-circular clips; a torsion spring 42 is sleeved on the connecting shaft 41; and the other ends of the two sets of semi-circular clips are fixed by bolts.

[0033] Specifically, two sets of identical semi-annular clips are connected by a connecting shaft 41 and a torsion spring 42. When connecting the feed pipe 3 and the conveying pipe 5, the two sets of identical semi-annular clips can be clipped onto the top of the feed pipe 3 and the bottom of the conveying pipe 5. In conjunction with the rubber strip set inside the semi-annular clips, the sealing between the conveying pipe 5 and the feed pipe 3 can be increased, effectively reducing powder leakage.

[0034] In one embodiment of the present invention, a material feeding assembly is provided on the top cover 2, and the material feeding assembly consists of a top plate 24, a connecting rod 25, an elastic band 21, a connecting plate 22, an elastic plate 23, and a first spring 28; the elastic band 21 is fixed to the bottom of the top cover 2, and the connecting plate 22 is fixed to the bottom of the elastic band 21; the elastic plate 23 is circumferentially connected to the bottom of the connecting plate 22; the connecting rod 25 passes through the top cover 2, and the top plate 24 is fixed to the top of the connecting rod 25; the bottom of the connecting rod 25 is located inside the receiving hopper 1; the first spring 28 is sleeved on the end of the connecting rod 25 located inside the receiving hopper 1.

[0035] Specifically, the material feeding component on the top cover 2 can be used when there is agglomerated powder on the filter screen 6. When the agglomerated powder falls onto the filter screen 6, the top plate 24 is pressed down manually, and the connecting rod 25 drives the bottom connecting plate 22 to move downward. During the downward movement of the connecting rod 25 and the connecting plate 22, the first spring 28 and the elastic band 21 are stretched, and therefore have a certain elastic potential energy. The downward movement of the connecting plate 22 will cause the elastic plate 23 at its bottom to come into contact with the agglomerated powder on the filter screen 6, and squeeze the agglomerated powder onto the filter screen 6. Therefore, the agglomerated powder will be separated into several small powder particles, which will eventually pass through the filter screen 6 and enter the bottom connecting pipe 11. This avoids the situation where the powder is trapped on the filter screen 6 due to its large size. Long-term operation may cause the filter screen 6 to become blocked. The intermittent movement of the material feeding component can prevent the filter screen 6 from becoming blocked.

[0036] In one embodiment of the present invention, a fixing block 26 is fixedly connected to the top cover 2, and the fixing block 26 is arranged at the position where the connecting rod 25 passes through the top cover 2; a brush bristle 27 is fixedly connected to the inner side of the fixing block 26, and the brush bristle 27 contacts the side wall of the connecting rod 25.

[0037] Specifically, when the connecting rod 25 moves, in order to prevent powder leakage at the connection between the connecting rod 25 and the top cover 2, the brush bristles 27 set inside the fixing block 26 can seal the connection between the connecting rod 25 and the top cover 2, preventing powder leakage. At the same time, the brush bristles 27 can clean the connecting rod 25, preventing the powder adhering to the connecting rod 25 from leaking out, which is beneficial to protecting the surrounding air quality.

[0038] In one embodiment of the present invention, the elastic plate 23 has an L-shaped structure; the bottom of the connecting plate 22 is provided with a central groove corresponding to the feed pipe 3, and the elastic plate 23 is fixed to the outside of the central groove.

[0039] Specifically, the elastic plate 23 has an "L"-shaped structure. Therefore, when the connecting plate 22 drives it to contact the agglomerated powder at the bottom, it can use the elastic plate 23 to press the agglomerated powder tightly onto the filter screen 6. At the same time, it has a certain buffering effect, which can achieve the effect of combing the agglomerated powder.

[0040] In one embodiment of the present invention, the material feeding assembly is arranged at the upper end of the filter screen 6, and both the filter screen 6 and the material feeding assembly are arranged in the receiving hopper 1.

[0041] In one embodiment of the present invention, the top plate 24 has an annular structure, and the feed pipe 3 passes through the middle of the top plate 24.

[0042] Specifically, the top plate 24 has a ring structure. Therefore, when the top plate 24 with a ring structure is pressed manually, the connecting rod 25 can be used to indirectly drive the bottom connecting plate 22 to move in the receiving hopper 1, thereby achieving the function of unblocking the agglomerated powder.

[0043] Working principle: Traditional polymer feeding funnels are generally straight pipe feeding ports. However, due to the lack of practicality of straight pipe feeding ports, problems such as powder leakage, inability to detect abnormalities, and blockage of pipes by agglomerated materials occur in the actual production process, which further affects the preparation of chemical auxiliary powders.

[0044] This device replaces the original straight-through discharge port with a conical receiving hopper 1. Therefore, when powder is spirally fed from the conveying pipe 5 and discharged into the receiving hopper 1 through the feeding pipe 3, the sealing between the feeding pipe 3 and the conveying pipe 5 is improved because they are fixed together by a snap-fit ​​4. Simultaneously, because a rubber strip is installed at the connection between the feeding pipe 3 and the receiving hopper 1, excessive powder leakage does not occur when the powder moves into the receiving hopper 1. After the powder enters the receiving hopper 1, the top cover 2 can be manually moved up and down to observe the spiral powder feeding inside the receiving hopper 1, facilitating timely handling of any abnormalities and preventing greater losses. Furthermore, to prevent clumps of powder from falling into the connecting pipe 11 and causing blockage, a filter screen 6 installed inside the receiving hopper 1 intercepts clumps of powder, thus preventing blockage and facilitating powder processing.

[0045] A locking block is provided at the end of the connection between the conveying pipe 5 and the feed pipe 3. Therefore, when the feed pipe 3 and the conveying pipe 5 are connected by the buckle 4, the sealing between the conveying pipe 5 and the feed pipe 3 can be increased by arranging a rubber strip on the inner side of the buckle 4. Two sets of semi-circular locking strips with the same structure are connected by a set of connecting shaft 41 and torsion spring 42. When connecting the feed pipe 3 and the conveying pipe 5, the two sets of semi-circular locking strips with the same structure can be snapped onto the top of the feed pipe 3 and the bottom of the conveying pipe 5. In conjunction with the rubber strip set on the inner side of the semi-circular locking strip, the sealing between the conveying pipe 5 and the feed pipe 3 can be increased, effectively reducing the leakage of powder.

[0046] Meanwhile, the material unloading component on the top cover 2 can be used when there is agglomerated powder on the filter screen 6. When the agglomerated powder falls onto the filter screen 6, the top plate 24 is pressed down manually, and the connecting rod 25 drives the bottom connecting plate 22 to move downward. During the process of the connecting rod 25 driving the connecting plate 22 to move downward, the first spring 28 and the elastic band 21 are stretched, and therefore have a certain elastic potential energy. The downward movement of the connecting plate 22 will cause its bottom elastic plate 23 to come into contact with the agglomerated powder on the filter screen 6, and squeeze the agglomerated powder onto the filter screen 6. Therefore, the agglomerated powder will be separated into several small powder particles, which will eventually pass through the filter screen 6 and enter the bottom connecting pipe 11. This avoids the situation where the powder is trapped on the filter screen 6 due to its large size. Long-term operation may cause the filter screen 6 to become blocked. The intermittent movement of the material unloading component can avoid the blockage of the filter screen 6.
