Description

Technical Field

[0001] The present application relates to the technical field of material transportation, and in particular to a liquid material feeding device. Background Art

[0002] A dryer is a mechanical device that uses heat energy to reduce the moisture content of materials. It is used to dry objects and is often used in the chemical, pharmaceutical, food and other industries. It is suitable for drying powdered, granular and fibrous materials. In the process of drying liquid materials, liquid material feeding equipment is required to continuously supply the liquid material to the dryer.

[0003] For example, in the chemical industry, when preparing fertilizers, it is necessary to go through the steps of raw material batching, stirring and mixing, drying and screening. Among them, before drying, the raw materials need to be stirred and mixed, and then transported to the dryer for drying. Since the raw materials for preparing fertilizers are usually placed in storage barrels or storage tanks, long-term storage will cause sedimentation and stratification in the fertilizer raw materials, resulting in the density of the upper layer of raw materials being lower than the density of the lower layer of raw materials. The fertilizer raw materials with sedimentation and stratification cannot be dried directly, because in the early stage of transporting the fertilizer raw materials to the dryer, the transported liquid will contain a large amount of water, which will affect the quality of the fertilizer. Therefore, further mixing is required before drying.

[0004] When mixing fertilizers that have deposited, it is difficult to meet the mixing requirements in a single mixing operation, which not only affects the practicality of the liquid material, but also causes a large amount of solids to remain in the feeding equipment, affecting normal drying operations.

[0005] Therefore, for some liquid materials with high mixing requirements, setting up a single mixing device cannot meet the mixing requirements, so it is necessary to provide a liquid material feeding device that can be mixed multiple times to solve the above problem.

[0044] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0045] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0046] Example 1:

[0047] like Figure 1 As shown, this embodiment provides a liquid material feeding device, including a base 1, a mounting plate 11 is fixed on the base 1, and the base 1 and the mounting plate 11 constitute a supporting portion;

[0048] The mounting plate 11 is provided with a mounting seat 14, on which a plurality of pipes are fixedly mounted. The pipes are used to transport liquid materials. The pipes include a liquid inlet pipe 12, one end of which serves as a feed end. The feed end is used to supply the liquid material to be transported, and the feed end is provided with a pumping device (not shown in the figure) to pump the liquid material.

[0049] The other end of the liquid inlet pipe 12 is connected to a mixing assembly 2, which is used to receive the liquid material entering the liquid inlet pipe 12 and stir and mix the liquid material. Specifically, Figure 2As shown, the mixing assembly 2 includes a mixing tube 21, which is connected to the liquid inlet pipe 12. A stirring blade 22 is provided in the mixing tube 21. The stirring blade 22 is suitable for rotating in the mixing tube 21 to stir and mix the liquid material passing through the mixing tube 21;

[0050] In order to mix the transported liquid material multiple times, several groups of mixing components 2 are provided on the mounting plate 11, and the water outlet end of each mixing component 2 is connected to the water inlet end of the next group of mixing components 2, and the water outlet end of the last mixing component 2 is connected to a liquid outlet pipe 13, which is used to receive the mixed liquid material, and the liquid outlet pipe 13 is connected to a dryer (not shown in the figure). After the liquid material is mixed multiple times, it is transported from the liquid outlet pipe 13 to the dryer for drying.

[0051] Example 2:

[0052] In the technical solution of the above-mentioned embodiment 1, by setting up multiple mixing components 2, the liquid material to be transported is mixed multiple times to improve the mixing effect. However, in the actual implementation process, too many mixing times of the liquid material will also bring negative effects. For example, in some materials, too long mixing time and too many mixing times will cause stratification and segregation. Therefore, it is necessary to judge the liquid material during the mixing process and export the liquid material that meets the mixing requirements in time. Specifically:

[0053] like Figure 1 As shown, the water outlet end of the mixing component 2 is connected to a screening component 3, which is used to judge the mixed liquid material, screen and export the liquid material that meets the requirements in time to prevent excessive mixing;

[0054] like Figure 3 As shown, the screening assembly 3 includes a screening cylinder 31, which is connected to the output end of the mixing assembly 2 through a pipeline. The screening cylinder 31 has an inner cavity, and the inner cavity is connected to a first screening tube 32 and a second screening tube 33. The first screening tube 32 is used to discharge liquid materials that meet the mixing conditions, and the second screening tube 33 is used to discharge liquid materials that do not meet the mixing conditions.

[0055] like Figure 4 As shown, a guide cylinder 34 is provided in the screening cylinder 31. The guide cylinder 34 is provided with a plurality of water outlets in the circumferential direction. The water outlets are used to guide the liquid material entering the guide cylinder 34 along the circumferential direction to prevent the liquid material from accumulating together and affecting the screening and exporting.

[0056] like Figure 5 As shown, the bottom of the screening cylinder 31 has a water outlet 36, and the water outlet 36 is connected to a liquid storage pipe 35, and the liquid storage pipe 35 is used to receive the liquid material introduced into the screening cylinder 31;

[0057] like Figure 3 As shown, the liquid storage pipe 35 is connected to a circulation pipe 37, and the other end of the circulation pipe 37 is connected to the feed end. Under the pumping of the pumping device, the liquid material can be circulated and screened;

[0058] like Figure 5 As shown, a first float bladder 311 is disposed within the screening cylinder 31. The first float bladder 311 can slide vertically on the inner wall of the screening cylinder 31 (the specific connection method will be described below). The first float bladder 311 is connected to a liquid filling hose 312. A liquid filling port 316 is provided at one end of the liquid filling hose 312. A counterweight liquid is fed into the first float bladder 311 through the liquid filling port 316, allowing the first float bladder 311 to move within the screening cylinder 31.

[0059] The lower end of the first float bladder 311 is provided with a connecting block 313. The connecting block 313 is a flexible structure and has a hook at the lower end of the connecting block 313. The second float bladder 315 is hung on the hook. The second float bladder 315 is also connected to the liquid filling hose 312 to facilitate filling the second float bladder 315 with liquid.

[0060] At the same time, the weight of the second float bladder 315 is greater than that of the first float bladder 311, and a slide 314 is fixedly installed on the inner wall of the screening cylinder 31, just below the first float bladder 311. The second float bladder 315 is slidably mounted on the slide 314, and the slide 314 is disposed at the connection between the first screening tube 32, the second screening tube 33 and the screening cylinder 31. Therefore, in the initial state, the second float bladder 315 completely covers the connection between the first screening tube 32, the second screening tube 33 and the screening cylinder 31, thereby preventing the mixed liquid in the screening cylinder 31 from flowing out of the first screening tube 32, the second screening tube 33.

[0061] like Figure 8 As shown, a limit block 39 is provided at the lower end of the first float bladder 311, between the connecting block 313 and the inner wall of the screening cylinder 31. A through limit groove 40 is provided on a side of the limit block 39 close to the screening cylinder 31. The limit groove 40 is provided along the moving direction of the first float bladder 311.

[0062] A top block 38 is fixedly mounted on the inner wall of the screening cylinder 31 at a position relative to the limiting groove 40. The top block 38 is adapted to be inserted into the limiting groove 40 and protrudes from the limiting groove 40 to form a protrusion. At the same time, a protrusion 41 is provided on the connecting block 313 at a position relative to the top block 38. Since the limiting groove 40 is through-set, the protrusion on the top block 38 can contact the protrusion 41, and the limiting groove 40 and the top block 38 are in sliding cooperation. Thus, the sliding cooperation between the top block 38 and the limiting groove 40 can drive the first float bladder 311 to slide in the vertical direction.

[0063] The protrusion 41 has an inclined surface, the upper surface of which is inclined in a direction away from the connecting block 313 and gradually decreases in height in a direction away from the connecting block 313. At the same time, because the inclined surface and the connecting block 313 are an integral flexible structure, when the first float bladder 311 moves upward, after the inclined surface of the protrusion 41 contacts the top block 38, the top block 38 can slide along the inclined surface of the protrusion 41 and cause the connecting block 313 to deform laterally, so that the hook at the lower end of the connecting block 313 moves laterally with the connecting block 313. When the connecting block 313 is deformed to the maximum position, the hook can be separated from the second float bladder 315, and the top block 38 can pass over the protrusion 41 and reach the lower end of the protrusion 41.

[0064] A button 23 is provided at the upper end of the first float bladder 311. One end of the button 23 contacts the upper end of the first float bladder 311. The button 23 is provided at the upper end of the screening drum 31, and a spring is provided between the button 23 and the screening drum 31. By pressing the button 23, the button 23 pushes the first float bladder 311 downward. After moving to the hooking position of the connecting block 313 and the second float bladder 315, the hook is re-hooked with the second float bladder 315.

[0065] During the implementation of this embodiment, a balancing liquid is first charged through the liquid filling port 316. The density of the balancing liquid is the same as the density of the liquid material to be transported when it meets the mixing requirements. The balancing liquid enters the second float bladder 315 and the first float bladder 311 respectively through the liquid filling hose 312. At this time, the second float bladder 315 is in the initial state, and the connection between the first screening tube 32 and the second screening tube 33 is closed. After the filling is completed, the pumping device at the liquid inlet pipe 12 is opened, allowing the liquid material to enter the mixing assembly 2 from the liquid inlet pipe 12 for mixing. The mixed liquid material enters the screening cylinder 31 through the pipeline, and fills the liquid storage pipe 35 as the liquid material in the pipe increases.

[0066] When the liquid material in the liquid storage pipe 35 continues to rise and accumulates in the inner cavity of the screening cylinder 31, since the first float bag 311 and the second float bag 315 are filled with a balancing liquid that meets the mixing requirements of the liquid material, when the liquid material in the screening cylinder 31 is not completely mixed, the density of the connection formed by the first float bag 311 and the second float bag 315 will be lower than the density of the balancing liquid. As the liquid material in the circulation pipe 37 is further pumped and mixed, the degree of mixing of the liquid material in the screening cylinder 31 will gradually increase. When the liquid material in the screening cylinder 31 is not completely mixed, the connection formed by the first float bag 311 and the second float bag 315 will not move. Therefore, the second float bag 315 can block the connection between the first screening tube 32 and the second screening tube 33. The liquid material in the screening cylinder 31 will be pumped back to the liquid inlet pipe 12 through the circulation pipe 37 for repeated mixing.

[0067] When the mixing degree of the liquid material in the screening cylinder 31 gradually increases and reaches the mixing requirement, the connection body formed by the first float bladder 311 and the second float bladder 315 moves upward due to the buoyancy force, and the second float bladder 315 is able to leave the connection port of the second screening tube 33, thereby exposing the connection port of the second screening tube 33. The liquid material in the screening cylinder 31 will flow out through the second screening tube 33, and the screening of the liquid material in the screening cylinder 31 will be completed.

[0068] When the liquid material in the screening drum 31 is completely mixed, its density will further increase. The connection formed by the first float 311 and the second float 315 will continue to move upward due to the buoyancy. After the protrusion 41 is lifted by the lifting block 38, the connecting block 313 and the second float 315 are separated, thereby separating the connection formed by the first float 311 and the second float 315. Since the weight of the second float 315 is greater than the weight of the first float 311, after the connection formed by the first float 311 and the second float 315 is separated, the second float 315 will move downward along the slide 314 due to gravity until it falls to the bottom of the slide 314. At this time, the connection port of the first screening tube 32 is exposed, and the liquid material in the screening drum 31 will enter the first screening tube 32.

[0069] It should be noted that according to Archimedes' principle, the buoyancy of an object is equal to the volume of the liquid it displaces multiplied by the density of the liquid. Since the density of the liquid is constant, different buoyancy will be generated when the object has different displacement volumes. In this embodiment, the first float bladder 311 and the second float bladder 315 are completely immersed in the liquid, and the volume of the connected body formed by them is significantly larger than the volume of the first float bladder 311 or the second float bladder 315. At the same time, the weight of the second float bladder 315 is greater than the weight of the first float bladder 311. Therefore, the first float bladder 311 and the second float bladder 315 are both immersed in the liquid. When the first float 311 and the second float 315 are connected, the whole body tends to rise. When the first float 311 and the second float 315 are separated, since the weight of the second float 315 is greater than the weight of the first float 311, and the drainage volume of the separated first float 311 and the second float 315 is less than the drainage volume when they are connected, the second float 315 slides downward along the slide 314, exposing the connection port of the first screening tube 32, and the liquid material in the screening cylinder 31 enters the first screening tube 32.

[0070] After the liquid material to be transported is replaced, since the hook of the connecting block 313 and the hooking position of the second float bladder 315 are separated at this time, it is necessary to press the button 23 to move the first float bladder 311 downward. After moving to the hooking position of the connecting block 313 and the second float bladder 315, the hook will be re-hooked with the second float bladder 315, thereby continuing the mixing, transportation and screening.

[0071] By providing the first float 311 and the second float 315, and providing the connecting block 313 on the first float 311 to connect with the second float 315, when the first float 311 and the second float 315 are filled with the weight liquid, since the density of the liquid material that is not completely mixed is higher than the density of the weight liquid, the first float 311 and the second float 315 will immediately move upward, thereby exposing the connection port of the second screening tube 33 and closing the connection port of the first screening tube 32, so that the liquid material pumped into the screening cylinder 31 in the initial stage does not reach the mixing requirement. The required liquid material will enter the second screening tube 33; when the liquid material in the screening cylinder 31 is completely mixed, its density will further increase, so the first float bladder 311 and the second float bladder 315 will continue to move upward until the top block 38 pushes the protrusion 41 open, separating the connecting block 313 from the second float bladder 315. The second float bladder 315 closes the second screening tube 33 under the action of gravity, and the mixed liquid material can flow out of the first screening tube 32, thereby achieving the screening of liquid materials that do not meet the mixing requirements and those that meet the mixing requirements.

[0072] Example 3:

[0073] In the above embodiment, the mixed liquid material is screened by the screening component 3, and different liquid materials are discharged from the first screening tube 32 and the second screening tube 33 according to the degree of mixing. According to the second embodiment, the first screening tube 32 is the outlet for the completely mixed liquid material, and the second screening tube 33 is the outlet for the unmixed liquid material. The completely mixed liquid material can be directly introduced into the dryer through the liquid outlet pipe 13, while the unmixed liquid material requires further mixing. Therefore, the screened liquid material needs to be diverted by the diversion component 5. Specifically:

[0074] like Figure 6 As shown, the diverter assembly 5 includes a diverter valve 51, which is arranged below the liquid storage tube 35. The diverter valve 51 has an inner cavity, and a chute 53 is provided in the inner cavity. A stopper 52 is also provided in the diverter valve 51, and a slider 57 is provided on the stopper 52 to match the chute 53. The two ends of the diverter valve 51 are respectively connected to the mixing assembly 2 and the liquid outlet pipe 13;

[0075] like Figure 9As shown, a connecting rod 54 is provided on the stopper 52, and a plugging piece 55 is provided at one end of the connecting rod 54. The size of the plugging piece 55 matches the inner diameter of the first screening tube 32. When the plugging piece 55 is located in the first screening tube 32, the plugging piece 55 can seal the first screening tube 32. At the same time, a diverter hole 56 is provided in the first screening tube 32. When the mixed liquid material in the second screening tube 33 falls, the hydraulic pressure in the tube pushes the plugging piece 55 toward the diverter valve 51, thereby moving the stopper 52. When the plugging piece 55 moves to one side of the diverter hole 56, the liquid material in the first screening tube 32 will fall into the diverter valve 51 through the diverter hole 56. Since the stopper 52 is now moved to the side of the diverter valve 51 away from the liquid outlet pipe 13, the liquid material falling into the diverter valve 51 will enter the liquid outlet pipe 13 and then flow into the dryer connected to the liquid outlet pipe 13.

[0076] The other end of the stopper 52 is connected to the second screening pipe 33 through the same principle, and is used to transport the incompletely mixed liquid material in the second screening pipe 33 to the mixing pipe 21, which will not be described in detail here.

[0077] In this embodiment, a diverter valve 51 is provided with a slidable stopper 52 in the diverter valve 51. When the liquid material in the first screening tube 32 or the second screening tube 33 falls, the generated hydraulic pressure drives the stopper 52 to move, exposing the diverter hole 56, thereby diverting the liquid material in the first screening tube 32 and the second screening tube 33. The completely mixed liquid material in the first screening tube 32 is directly transported to the dryer, while the liquid material in the second screening tube 33 is connected to the mixing tube 21 for further mixing.

[0078] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
