Description

Technical Field

[0001] This invention relates to the field of transfer equipment technology, and in particular to a cross-workshop transfer equipment for slurry materials. Background Technology

[0002] Slurry materials are widely used in industrial production, such as chemical, metallurgical, and food processing. Their properties are between those of liquids and solids, containing a large number of suspended particles. They are prone to sedimentation and agglomeration during transportation, leading to pipeline blockage and equipment failure. Inter-workshop transfer is a critical link in the production process, but the poor flowability and easy settling of slurry materials make long-distance transportation particularly difficult.

[0003] In existing technologies, conventional pipeline systems are commonly used for transportation, relying on pumping equipment for power. However, due to the velocity gradient that easily forms in the flow of slurry materials, particulate matter gradually settles to the bottom of the pipeline due to gravity, especially at pipeline bends and low-velocity areas where sedimentation is more pronounced. Over long-term operation, the accumulation of sediment can reduce the effective pipe diameter, increase transportation resistance, and even cause complete blockage, requiring shutdown and cleaning, which seriously affects production efficiency and equipment stability.

[0004] To alleviate sedimentation problems, existing technologies often employ methods such as increasing transport pressure, tilting pipelines, or adding agitators. However, these methods have significant limitations: increasing pressure increases energy consumption and may damage fragile particles; tilting pipelines is limited by site constraints and cannot fundamentally solve the sedimentation problem; agitators can only provide localized improvements, are difficult to cover the entire transport system, and have high maintenance costs. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a cross-workshop transfer device for slurry materials. By combining a variable-diameter pipe to adjust the flow rate, a drive mechanism to eliminate dead zones in the flow, and a pulse mechanism to impact deposits, this invention solves the technical problems of easy deposition and blockage of slurry materials during long-distance pipeline transportation. Specifically, this is achieved through the following technical solutions.

[0006] This invention discloses a cross-workshop transfer device for slurry-like materials, comprising: The conveying channel is formed by connecting several first pipes, second pipes and reducing pipes in series.

[0010] Preferably, a diaphragm is provided between the upper cavity and the lower cavity, and the outer edge of the diaphragm is fixed by a mounting ring to divide the cavity into a first chamber and a second chamber, with the first chamber being close to the upper cavity and the second chamber being close to the lower cavity.

[0011] Preferably, a valve is installed on the upper cavity and is connected to an external air supply pipe for periodically supplying gas to the first chamber, causing the diaphragm to reciprocate, thereby realizing the pulse pumping of liquid.

[0012] Preferably, the one-way valve includes a valve tube with sealing rings at both ends for sealing installation inside the end tube. Several support rods are fixed on the inner surface of the valve tube, with the inner side of the support rods fitting against the outer surface of the sealing ball. A stop block is fixed at the downstream end of the valve tube, and a limit ring is fixed at the upstream end. The limit ring is used to seal against the sealing ball to prevent liquid backflow.

[0013] Preferably, the reducing pipe has an installation hole on its side wall, the installation hole is connected to the mounting pipe, and the installation hole is beveled on the side closest to the inner surface of the reducing pipe.

Detailed Implementation

[0024] The features and exemplary embodiments of various aspects of the present invention will now be described in detail. To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the invention.

[0025] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of the invention. It should also be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly, for example, referring to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0026] An embodiment of the present invention provides a cross-workshop transfer device for slurry materials, see below. Figure 1 , Figure 2 The inter-workshop transfer equipment for the slurry material includes a first pipe 101, a second pipe 102, a reducing pipe 103, a drive mechanism 200, and a pulse mechanism 300. Several first pipes 101, second pipes 102, and reducing pipes 103 are connected in series to form a conveying channel. The large-diameter port of the reducing pipe 103 is connected to the first pipe 101, and the small-diameter port of the reducing pipe 103 is connected to the second pipe 102. The reducing pipes 103 installed at both ends of the first pipe 101 are symmetrically distributed, and the reducing pipes 103 installed at both ends of the second pipe 102 are also symmetrically distributed.

[0027] Among them, such as Figure 2 As shown, one side of the reducing pipe 103 is perpendicular to its end face, and the other side is inclined. The side of the reducing pipe 103 perpendicular to its end face is collinear with the lowest point of the inner diameter of the first pipe 101 and the second pipe 102. This structure ensures that the lowest point of the inner diameter of the first pipe 101, the second pipe 102 and the reducing pipe 103 are on the same horizontal plane, avoiding the slope at the bottom of the channel from causing material deposition, which would block the channel and ultimately affect the transfer effect of slurry materials.

[0028] The above structure can adjust the transfer speed of slurry material inside the channel by changing the diameter of the variable diameter pipe 103. Because under constant flow conditions, the material flow rate increases when the inner diameter of the pipe decreases, and the material flow rate decreases when the inner diameter of the pipe increases. Therefore, by changing the diameter, the inner diameter of the channel changes in stages, which can effectively adjust the flow rate of the material and avoid the deposition of slurry material caused by the overall flow rate being stable.

[0029] See Figure 1 , Figure 3 The drive mechanism 200 is located at the corner of the conveying channel. The drive mechanism 200 includes a variable diameter cylinder 201, an end cap 202, and an inlet pipe 203. The large diameter port of the variable diameter cylinder 201 is sealed and fixedly installed with the end cap 202. The small diameter end of the variable diameter cylinder 201 is fixedly connected to the downstream pipe. The side of the variable diameter cylinder 201 is fixedly connected to the inlet pipe 203. The inlet pipe 203 is fixedly connected to the upstream pipe.

[0030] A drive motor 204 is fixedly installed on the outside of the end cover 202. The output shaft of the drive motor 204 passes through the end cover 202 and extends into the inside of the variable diameter cylinder 201. A first turbo fan 205 and a second turbo fan 206 are fixedly installed on the output shaft of the drive motor 204 in sequence. The first turbo fan 205 and the second turbo fan 206 have the same structure. The first turbo fan 205 is close to the end cover 202, and the second turbo fan 206 is away from the end cover 202. The side of the first turbo fan 205 faces the inlet pipe 203.

[0031] Because the liquid flow will be turbulent at the corner of the channel, and the liquid flow direction will be unstable due to the impact of the liquid flow on the inner wall of the channel, dead corners of liquid flow impact are likely to occur, resulting in material deposition. In particular, the slurry-like material involved in this invention is more likely to cause channel blockage due to material deposition.

[0032] In this embodiment, a drive motor 204 is provided in the drive mechanism 200 to drive the first vortex fan 205 and the second vortex fan 206 in the variable diameter cylinder 201 to rotate synchronously. On the one hand, the first vortex fan 205 improves the flow state of the slurry material entering the variable diameter cylinder 201, so that the slurry material moves fully under the action of the rotation of the first vortex fan 205 after entering the variable diameter cylinder 201, avoiding the material deposition caused by the impact dead zone when the slurry material first enters the variable diameter cylinder 201. On the other hand, the synchronous rotation of the first vortex fan 205 and the second vortex fan 206 enhances the axial thrust of the variable diameter cylinder 201, thereby increasing the pressure of the liquid flow inside the channel, increasing the conveying speed of the slurry material, and reducing deposition.

[0033] See Figure 4 , Figure 5 The pulse mechanism 300 is installed on the side of the first pipe 101. The pulse mechanism 300 includes an installation pipe 301, a connecting pipe 302, and a pumping part 310. The installation pipe 301 and the connecting pipe 302 are fixedly connected. There are two sets of installation pipes 301 and connecting pipes 302. The two sets of connecting pipes 302 are fixedly connected to the inlet end and the outlet end of the pumping part 310, respectively. The first set of installation pipes 301 is fixedly connected to the top of the side wall of the reducer 103 downstream of the first pipe 101. The second set of installation pipes 301 is fixedly connected to the bottom of the side wall of the reducer 103 upstream of the first pipe 101.

[0034] Among them, the top of the side wall of the reducing pipe 103 downstream of the first pipe 101 and the bottom of the side wall of the reducing pipe 103 upstream of the first pipe 101 are provided with mounting holes 303, and the first pipe 101 is connected to the mounting pipe 301 through the mounting holes 303. The mounting holes 303 are chamfered on the side near the inner surface of the reducing pipe 103.

[0035] In this embodiment, through the above structure, the pumping unit 310 pumps the upper clear liquid inside the reducing pipe 103 located downstream of the first pipe 101 to the bottom of the reducing pipe 103 upstream of the first pipe 101, in order to impact some of the material deposited at the bottom of the channel, disrupt its deposition state, and avoid pipe blockage caused by long-term deposition.

[0036] The slurry material flows in the channel. When it reaches the position of the first pipe 101, the flow rate of the slurry material slows down because both ends of the first pipe 101 are connected to the large diameter of the reducer 103. This can easily lead to material deposition, especially at the connection between the first pipe 101 and the reducer 103, where material deposition is likely to occur due to the joint gap. Therefore, the pumping unit 310 transports the upper clear liquid in the downstream pipe to the bottom of the upstream channel. The pulsed liquid flow mixes the deposited material at the bottom with the material in the pipe again, allowing it to re-participate in the flow and transport, thereby reducing the probability of channel blockage.

[0037] For a further explanation of the above embodiments, see Figure 6 , Figure 7 The pumping unit 310 includes an upper cavity 311 and a lower cavity 312. The upper cavity 311 is sealed and fixed to the lower cavity 312 by several bolts, and the upper cavity 311 and the lower cavity 312 form a cavity. Both ends of the lower cavity 312 are fixedly connected to the end pipe 313. The end pipe 313 is fixedly connected to the connecting pipe 302, and a one-way valve 320 is provided inside the end pipe 313. The one-way valve 320 is used to control the flow direction of the liquid inside the lower cavity 312 to ensure that the liquid flows from the downstream end of the first pipe 101 to the upstream end of the first pipe 101.

[0038] A diaphragm 314 is provided between the upper cavity 311 and the lower cavity 312. The outer edge of the diaphragm 314 is fixed to the mounting ring 315. The mounting ring 315 is fixedly installed between the upper cavity 311 and the lower cavity 312, dividing the cavity formed by the upper cavity 311 and the lower cavity 312 into two independent chambers.

[0039] Among them, the end faces of the upper cavity 311 and the lower cavity 312 that are in sealed contact are respectively provided with annular clearance grooves, and the mounting ring 315 is disposed inside the clearance groove to realize the fixed installation of the diaphragm 314.

[0040] A first mounting block 316 is provided in the middle of the diaphragm 314 near the lower cavity 312. A mounting shaft is coaxially fixed to the first mounting block 316. The mounting shaft passes through the diaphragm 314 and the second mounting block 318 and is fixed to the first end of the guide rod 317. The second mounting block 318 is provided on the side of the diaphragm 314 near the upper cavity 311. The first end of the guide rod 317 abuts against the second mounting block 318. The guide rod 317 is slidably disposed inside the guide hole coaxially opened on the upper cavity 311. A limit plate is coaxially fixed to the second end of the guide rod 317.

[0041] The outer edges of the first mounting block 316 and the second mounting block 318 near the diaphragm 314 are rounded to prevent the sharp edges of the outer edges of the first mounting block 316 or the second mounting block 318 from scratching the diaphragm 314 and affecting the service life of the diaphragm 314.

[0042] See Figure 7 A valve 319 is also fixedly installed on the upper cavity 311. One end of the valve 319 is connected to the inside of the upper cavity 311 through a through hole opened on the upper cavity 311, and the other end of the valve 319 is connected to an external air supply pipe. The external air supply pipe periodically supplies gas into the upper cavity 311 through the valve 319.

[0043] For ease of understanding and description, in the two chambers formed by the diaphragm 314, the chamber closer to the upper chamber 311 is defined as the first chamber, and the chamber closer to the lower chamber 312 is defined as the second chamber. When the external gas supply pipe delivers high-pressure gas to the first chamber through the valve 319, the pressure inside the first chamber increases, driving the diaphragm 314 to move closer to the second chamber, thereby discharging the liquid from the second chamber. When the external gas supply pipe stops delivering gas to the first chamber, the pressure in the second chamber is greater than the pressure in the first chamber, driving the diaphragm 314 to move closer to the first chamber, thereby allowing the liquid to flow into the second chamber.

[0044] Based on the periodic high-pressure gas delivery through the external gas supply pipe, the pulse pumping effect of the pumping unit 310 can be achieved, thereby effectively avoiding channel blockage caused by material deposition at the upstream end of the first pipeline 101.

[0045] For a further explanation of the above embodiments, see Figure 8 The one-way valve 320 includes a valve tube 321. Both ends of the valve tube 321 are respectively provided with sealing rings 326 that fit tightly against their end faces. The valve tube 321 is sealed inside the end tube 313 by the sealing rings 326. Several support rods 322 are uniformly fixed on the inner surface of the valve tube 321 along its axial direction. The inner side of the support rods 322 fits against the outer surface of the sealing ball 323.

[0046] A stop 324 is fixedly installed at the downstream end of the valve pipe 321. The stop 324 has several flow holes for connecting the inside of the valve pipe 321 with the downstream side. The stop 324 can abut against the sealing ball 323 to limit the position of the sealing ball 323 and prevent the sealing ball 323 from flowing out of the valve pipe 321.

[0047] The upstream end of the valve tube 321 is coaxially fixed with the limiting ring 325. The inner surface of the limiting ring 325 can seal against the sealing ball 323 to restrict the backflow of liquid inside the valve tube 321.

[0048] The one-way valves 320, which are sealed inside the two end pipes 313, have the same structure and are set in the same direction, thereby ensuring that the direction of the liquid pumped by the pumping unit 310 is always consistent.

[0049] The embodiments described above are not exhaustive, nor do they limit the invention to any specific embodiments. Clearly, many modifications and variations can be made based on the above description. These embodiments are selected and specifically described in this specification to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to effectively utilize the invention and its modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the invention should be included within the scope of protection of the invention.
