Description

Technical Field

[0001] This invention relates to the field of chemical technology, and in particular to a portable water jet vacuum pumping system. Background Technology

[0002] Currently in chemical production, the hydraulic jet vacuum pumping device used for extracting mother liquor mainly consists of a hydraulic jet vacuum unit and its matching vacuum pack. The vacuum degree formed by the venturi tube is used to evacuate the inside of the vacuum pack. The material in the mother liquor tank is extracted by the pressure difference between the vacuum pack and the mother liquor tank. The main material of the whole is reinforced polypropylene.

[0003] Because the existing equipment is mainly made of reinforced polypropylene, after long-term use, local discoloration, cracking and aging have appeared on the surface of the equipment, resulting in thinning of the wall and reduction of strength. This poses safety hazards such as easy deformation of the plate wall and tearing of the weld. In addition, when the equipment is moved, the connecting pipes are repeatedly disassembled and reinstalled, which consumes a lot of manpower, material resources and time, resulting in unnecessary waste.

[0004] In actual use, the high-speed liquid flow through the Venturi tube cannot be utilized, resulting in high energy consumption of the overall equipment. The remaining energy cannot be effectively utilized, leading to a large amount of energy loss. Furthermore, when the high-speed liquid is introduced into the gas-liquid separator and the circulating water tank, it will cause certain damage to both, thus reducing their service life.

[0005] During the process of circulating water in the device, impurities on the inner wall of the pipe and impurities in the water will inevitably accumulate, which will easily lead to the accumulation of deposits on the inner wall of the pipe and directly affect the service life of the venturi tube and the water pump. To this end, the inventors have designed and developed a hydraulic jet vacuum pumping system that can be transferred according to the needs of use and can utilize the residual energy of high-speed circulating water. Summary of the Invention

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A portable hydraulic jet vacuum pumping system includes a circulating water tank, a filtration mechanism, a water pump, a venturi tube, and a gas-liquid separator connected in sequence by pipes. The main material of the above components is stainless steel. The bottom of the circulating water tank is provided with a channel steel frame, and the channel steel frame is provided with a mounting bracket for fixing the gas-liquid separator. A vacuum pack connected to the venturi tube by a pipe is also fixed on the mounting bracket.

[0008] The vacuum pack is equipped with a feed pipe for supplying material into its interior and a vacuum pipe for evacuating the interior. The vacuum pipe is connected to a venturi tube, and the venturi tube is equipped with a vacuum valve for controlling its opening and closing, as well as a one-way valve to prevent liquid from the venturi tube from flowing back into the venturi tube. The bottom of the vacuum pack is also equipped with a discharge pipe, and the vacuum pack is equipped with a vacuum gauge for detecting the vacuum level inside.

[0009] Preferably, the gas-liquid separator is connected to an exhaust pipe for venting gas and a water supply pipe connected to the output end of a venturi tube. The gas-liquid separator is also provided with a return pipe connected to a circulating water tank and a separation cylinder for gas-liquid separation treatment.

[0010] Preferably, the gas-liquid separator is provided with a cleaning mechanism that works with the separation cylinder to perform gas-liquid separation. The cleaning mechanism includes a baffle connected to the separation cylinder and a connecting rod for fixing the baffle. The connecting rod is provided with a movable sleeve, and the movable sleeve is provided with a scraper that acts on the top surface of the baffle.

[0011] Preferably, the cleaning mechanism further includes a reciprocating screw located at the bottom of the baffle, with a fixing strip fixed at the other end of the reciprocating screw and connected to the inner wall of the gas-liquid separator. A balance bar is sleeved on the reciprocating screw, and guide rods fixed to the scraper are provided at both ends of the balance bar. A cleaning plate is also provided on the reciprocating screw.

[0012] Preferably, the separation cylinder is provided with a hydraulic rotation mechanism that drives some components of the cleaning mechanism to rotate. The hydraulic rotation mechanism includes a ring fixed to the outer wall of the separation cylinder, an impact plate rotatably disposed on the ring, and a synchronization rod connected to the scraper on the impact plate.

[0013] Preferably, the filtration mechanism includes a first filter tube connected to a circulating water tank and a second filter tube connected to a water pump. A first pair of connecting pipes is sleeved on the first filter tube, and a second pair of connecting pipes is sleeved on the second filter tube and sealed to the first pair of connecting pipes. A filter disc is sealed between the first pair of connecting pipes and the second pair of connecting pipes.

[0014] Preferably, the first filter tube is provided with a first rotating shaft, the second filter tube is provided with a second rotating shaft, and the filter disc is connected to a bearing with a bidirectional mating block for splicing the first rotating shaft and the second rotating shaft.

[0015] Preferably, the first rotating shaft is provided with a scraper blade that fits against the inner wall of the first filter tube, and the second rotating shaft is provided with blades that are driven to rotate by water flow.

[0016] Preferably, the channel steel frame is provided with padding strips for easy transport by forklifts.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. By replacing the main components with stainless steel, the equipment as a whole can avoid local surface discoloration, cracking, aging and other phenomena during long-term use.

[0019] 2. By setting up a channel steel frame, pads, and mounting brackets, individual components are welded together using pipes. A forklift is used to insert the pads, and all components set on the channel steel frame are transported in a unified manner. This avoids the need for repeated disassembly and installation of connecting pipes due to equipment relocation, which would consume a lot of manpower, material resources, and time, resulting in unnecessary waste.

[0020] 3. By setting up the gas-liquid separator and utilizing the cooperation between the cleaning mechanism and the hydraulic rotation mechanism, the water flowing into the gas-liquid separator from the water supply pipe can impact the rotating impact plate, thereby driving the scraper to scrape off the deposits on the top surface of the baffle. Furthermore, through the transmission of the guide rod and the setting of the reciprocating screw, the cleaning plate can scrape off the deposits on the bottom of the inner wall of the gas-liquid separator.

[0021] 4. Through the setting of the filtration mechanism, the filter disc can be easily disassembled and installed by using the docking set between the first pair of pipes and the second pair of pipes. The flow rate of water from the first filter tube to the second filter tube drives the blades to rotate, and through transmission, the scraper blades scrape off the impurities on the inner wall of the first filter tube.

[0022] In summary, this invention overcomes the shortcomings of the prior art, has a reasonable design, replaces the materials used in its manufacture, extends the service life of the equipment, and utilizes the residual kinetic energy of the circulating water flow. While solving the problem of equipment damage caused by excessive water flow impact, it also prevents impurities in the circulating water flow from adhering to the inner wall of the equipment, thus possessing high social value and application prospects.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0035] Example 1

[0036] Reference Figure 1-2A portable water jet vacuum pumping system includes a circulating water tank 1, a filtration mechanism 2, a water pump 3, a venturi tube 4, and a gas-liquid separator 5 connected in sequence by pipes. The main material of the above components is stainless steel. The bottom of the circulating water tank 1 is provided with a channel steel frame 7. The channel steel frame 7 is provided with a mounting bracket 72 for fixing the gas-liquid separator 5. The mounting bracket 72 is also fixed with a vacuum bag 6 connected to the venturi tube 4 through a pipe. The channel steel frame 7 is provided with pads 71 ​​for transport by forklift.

[0037] The vacuum pack 6 is equipped with a feed pipe 61 for supplying material into its interior and a vacuum pipe 62 for evacuating the interior. The vacuum pipe 62 is equipped with a vent pipe 63 that connects to the venturi tube 4. The vent pipe 63 is equipped with a vacuum valve 631 that controls its opening and closing, and a one-way valve 632 that prevents liquid from flowing back into the vent pipe 63 from the venturi tube 4. The bottom of the vacuum pack 6 is also equipped with a discharge pipe 64 for discharging the material inside the vacuum pack 6. The vacuum pack 6 is equipped with a vacuum gauge to detect the vacuum level inside. The pipe connecting the feed pipe 61 to the external mother liquor tank needs to be equipped with a valve to prevent material from the mother liquor tank from entering the vacuum pack 6 during the vacuuming stage. A level gauge is connected to the outer wall of the vacuum pack 6 to observe the liquid level of the material contained inside the vacuum pack 6.

[0038] Specifically, the gas-liquid separator 5 is connected to an exhaust pipe 51 for exhausting gas and a water supply pipe 52 connected to the output end of the venturi tube 4. The gas-liquid separator 5 is also equipped with a return pipe 53 connected to the circulating water tank 1 and a separation cylinder 54 for gas-liquid separation. One end of the water supply pipe 52 inside the gas-liquid separator 5 is set as a bend. The setting angle of the bend is adapted to the setting angle of the impact plate 902. After the water flows through the water supply pipe 52 into the gas-liquid separator 5, the water flow can impact the impact plate 902, so that the impact plate 902 can rotate accordingly.

[0039] Example 2

[0040] Reference Figure 1 , Figure 3-6The difference between this embodiment and embodiment 1 is that the gas-liquid separator 5 is equipped with a cleaning mechanism 8 that works with the separation cylinder 54 to perform gas-liquid separation. The cleaning mechanism 8 includes a baffle 801 connected to the separation cylinder 54 and a connecting rod 802 for fixing the baffle 801. The connecting rod 802 is equipped with a movable sleeve 803, and the movable sleeve 803 is equipped with a scraper 804 that acts on the top surface of the baffle 801. The water flow after impacting the impact plate 902 will fall down under the action of gravity. The circulating water falls on the top surface of the baffle 801. After the flow is diverted by the baffle 801, the water flow is collected at the bottom of the inner cavity of the gas-liquid separator 5. The bottom of the scraper 804 is equipped with a silicone strip that fits against the top surface of the baffle 801. During the rotation of the scraper 804, the silicone strip scrapes off the impurities that flow down the top surface of the baffle 801 due to the water flow.

[0041] The cleaning mechanism 8 also includes a reciprocating screw 805 located at the bottom of the baffle 801. A fixing strip 809 connected to the inner wall of the gas-liquid separator 5 is fixed to the other end of the reciprocating screw 805. A balance strip 807 is mounted on the reciprocating screw 805 via a bearing sleeve. Guide rods 808, fixed to scraper strips 804, are located at both ends of the balance strip 807. A cleaning plate 806 is also mounted on the reciprocating screw 805 and movably connected to it. The connection between the cleaning plate 806 and the reciprocating screw 805 is achieved using a bearing, allowing the cleaning plate 806 to move vertically along the reciprocating screw 805 as it rotates with the guide rods 808. Both ends of the cleaning plate 806 contact the inner wall of the gas-liquid separator 5. During the rotation of the cleaning plate 806, it can scrape away the deposits on the inner wall of the gas-liquid separator 5, reducing the problem of a large overall area caused by the scraping range of the cleaning plate 806.

[0042] The separator 54 is equipped with a hydraulic rotation mechanism 9 that drives the components of the cleaning mechanism 8 to rotate. The hydraulic rotation mechanism 9 includes a ring 901 fixed to the outer wall of the separator 54. An impact plate 902 is rotatably mounted on the ring 901. The impact plate 902 is equipped with a synchronizing rod 903 connected to the scraper 804. The connection between the ring 901 and the separator 54 is fixed. The ring 901 is equipped with a base that rotates with it. The base is used to install the impact plate 902, so that the impact plate 902 can rotate relative to the separator 54 under the impact of water flow.

[0043] Example 3

[0044] Reference Figure 1 , Figure 7-9The difference between this embodiment and embodiment 1 is that the filtration mechanism 2 includes a first filter tube 201 connected to the circulating water tank 1 and a second filter tube 203 connected to the water pump 3. A first connecting pipe 202 is sleeved on the first filter tube 201, and a second connecting pipe 204 is sleeved on the second filter tube 203 and sealed to the first connecting pipe 202. A filter disc 205 is sealed between the first connecting pipe 202 and the second connecting pipe 204.

[0045] The first filter tube 201 is provided with a first rotating shaft 206, and the second filter tube 203 is provided with a second rotating shaft 207. The filter disc 205 is connected to a bearing with a bidirectional mating block 2051 for splicing the first rotating shaft 206 and the second rotating shaft 207. A sealing ring is provided at the connection between the first filter tube 201 and the first connecting pipe 202, and a sealing ring is also provided at the connection between the second filter tube 203 and the second connecting pipe 204. This prevents leakage at the connection between the first filter tube 201 and the first connecting pipe 202, and at the connection between the second filter tube 203 and the second connecting pipe 204, when the first connecting pipe 202 and the second connecting pipe 204 are sealed together. A locking block is provided at the position on the first connecting pipe 202 and the second connecting pipe 204 for splicing the filter disc 205, which matches the locking groove on the filter disc 205, so that the filter disc 205 will not rotate when it is clamped and sealed by the first connecting pipe 202 and the second connecting pipe 204.

[0046] The first rotating shaft 206 is provided with a scraper 2061 that fits against the inner wall of the first filter tube 201. The second rotating shaft 207 is provided with a blade 2071 that is driven to rotate by water flow. The two ends of the bidirectional docking block 2051 are respectively connected to the ends of the first rotating shaft 206 and the ends of the second rotating shaft 207 by an insertion splicing method, so that a transmission can be formed between the first rotating shaft 206 and the second rotating shaft 207. The bidirectional docking block 2051 rotates with the second rotating shaft 207 without affecting the sealing splice between the filter disc 205 and the first connecting pipe 202 and the second connecting pipe 204.

[0047] Working Principle: In this invention, circulating water is first introduced into the circulating water tank 1, filling it to 70% capacity. Then, the water pump 3 is turned on, allowing the circulating water in the tank 1 to pass sequentially through the filtration mechanism 2, the water pump 3, the venturi tube 4, the gas-liquid separator 5, and the circulating water tank 1, enabling circulation. When the water flows through the filtration mechanism 2 into the water pump 3, the water flow drives the blades 2071 to rotate, causing the scraper blades 2061 to scrape away the deposits on the inner wall of the first filter tube 201, preventing impurities from accumulating on the inner wall of the first filter tube 201. Impurities in the water are blocked by the filter disc 205, which can be replaced periodically. When the circulating water is pumped into the venturi tube 4 by the water pump 3, a vacuum chamber is created inside the venturi tube 4. The air guide pipe 63 is positioned at the vacuum chamber location, connecting to the venturi tube 4. The air extraction valve 631 is then opened, allowing the air to pass through the vacuum chamber. The pressure difference allows the gas inside the vacuum pack 6 to enter the venturi tube 4 through the gas guide pipe 63. The gas then follows the water flow through the water supply pipe 52 into the gas-liquid separator 5. With the cooperation of the separation cylinder 54 and the cleaning mechanism 8, the gas is discharged from the exhaust pipe 51, allowing the circulating water to re-enter the circulating water tank 1 through the return pipe 53. During the process of the circulating water flowing into the gas-liquid separator 5 through the water supply pipe 52, the impact of the water flow will push the impact plate 902, causing the impact plate 902 to rotate relative to the separation cylinder 54. Driven by the synchronous rod 903, the scraper 804 scrapes off the deposits on the top surface of the baffle 801. Then, driven by the guide rod 808 and the balance bar 807, the cleaning plate 806 rotates. While rotating, the cleaning plate 806 will move up and down according to the reciprocating thread on the reciprocating screw 805, so that the cleaning plate 806 can scrape off the deposits in the bottom area of ​​the inner wall of the gas-liquid separator 5.
