Description

[0001] The invention relates to the technical field of diaphragm pumps, in particular to a hydraulic hose type diaphragm pump. Background Art

[0002] A diaphragm pump is a commonly used industrial pump used to transport liquids from one place to another. Its working principle is to use a diaphragm to separate the liquid into two parts, and then achieve the suction and discharge of the liquid by periodically changing the pressure. A diaphragm pump usually consists of a pump body, two diaphragms, inlet and outlet valves and some connecting pipes. When the pressure in the pump body changes, the diaphragm will move, suck in the liquid and discharge it.

[0003] As disclosed in Chinese Patent Publication No. (CN113669236B), a hydraulic hose diaphragm pump includes: a pump body, a piston column and a main delivery pipe. The pump body is connected to the main delivery pipe through a pipe body, and the piston column is vertically connected to the pump body. A hydraulic hose diaphragm pump also includes: a diaphragm combination mechanism, the diaphragm combination mechanism includes: a corrugated telescopic hose, a diaphragm body and a fixed connecting ring, and the diaphragm combination mechanism is connected between the piston column and the pump body. The benefit of this invention is that it prevents the diaphragm body from being ruptured due to long-term reciprocating stretching of the middle part.

[0004] However, as in the above patent, there is a problem of poor liquid isolation effect when the diaphragm parts inside the diaphragm pump are disassembled, assembled and replaced. For example, in the above patent, when the diaphragm parts are disassembled, assembled and replaced, the space on one side of the diaphragm parts in the pump body needs to be isolated to avoid liquid leakage. However, as in the above patent, the pipeline is sealed by a gate plate, and the gate plate in this method is sealed by the circumferential rotation position of the gate plate when the screw sleeve and the ball screw are matched. However, in this method, there is no related fixing part on the outside of the ball screw. When the liquid flows, it will impact the gate plate and then cause the ball screw to rotate along the screw sleeve to produce a gap, resulting in liquid leakage, affecting the isolation effect. Summary of the invention

[0029] The sealing member 26 includes four connecting rods 261, four sealing sleeves 262 and four sealing gates 263. When the diaphragm member 32 inside the diaphragm pump is damaged and needs to be removed or installed, the movement of the electric push rod 23 is controlled to push the push plate 24 to move along the outside of the screw 21 through the movable sleeve 22, so that the sealing member 26 can seal or open the internal pipeline of the pump body 1.

The disassembly and assembly flange 33 is placed between the inner walls of the left and right sides, and the two pressure rings 34 are respectively fixed to the left and right sides of the disassembly and assembly flange 33.

The pressure ring 34 is inserted into the pressure groove by applying pressure through the disassembly flange 33 and the fastening bolts 35 to limit the diaphragm 32.

[0033] See also Figure 5 In order to discharge the diaphragm pump, the discharge mechanism 4 in this embodiment includes two liquid guide tubes 41, two control valves 42, two temporary storage tanks 43, two three-way pipes 44, two discharge pipes 45 and two return pipes 46. The two liquid guide tubes 41 are respectively connected to the left and right sides of the pump body 1, and the two control valves 42 are respectively fixed to the outer sides of the two liquid guide tubes 41. After the partition mechanism 2 in the diaphragm pump effectively blocks the internal pipeline of the pump body 1, the control valve 42 is opened so that the liquid in the partition space in the pump body 1 can be discharged outward along the liquid guide tube 41. The two temporary storage tanks 43 are connected to the pump body 1 through the control valve 42. 3 are respectively connected to the bottom ends of the two liquid guide pipes 41, and the two three-way pipes 44 are respectively connected to the bottom ends of the two temporary storage tanks 43. The discharged liquid first flows into the temporary storage tank 43, and then the liquid is discharged through the three-way pipe 44. At this time, according to maintenance requirements, the stop valve 47 of the discharge pipe 45 can be opened to facilitate the liquid to be discharged from the discharge pipe 45 to the outside for collection. The top ends of the two discharge pipes 45 are respectively connected to the left ends of the three-way pipe 44, one ends of the two return pipes 46 are connected to the right end of the three-way pipe 44, and the other end of the return pipe 46 is connected to the feed end of the pump body 1.

[0034] In this embodiment, the outer sides of the two discharge pipes 45 and the two return pipes 46 are fixed with stop valves 47, and the outer side of the temporary storage tank 43 is provided with a transparent observation panel. The stop valve 47 on the outer side of the return pipe 46 can be opened to change the flow channel so that the liquid can flow back to the pump body 1 for repeated pumping. This method can quickly discharge the excess liquid in the diaphragm pump, keep the inside of the pump body 1 clean, and facilitate the disassembly, assembly, replacement and use of the diaphragm member 32. The top end of the liquid guide tube 41 penetrates and extends to the inner wall of the pump body 1, and the outer sides of the two temporary storage tanks 43 are respectively fixed to the left and right sides of the pump body 1.

[0035] The working principle of the above embodiment is:

[0036] (1) When the diaphragm pump is used for disassembly and sealing of the diaphragm, when the diaphragm part 32 inside the diaphragm pump is damaged and needs to be disassembled or installed, the movement of the electric push rod 23 is controlled to push the push plate 24 to move along the outer side of the screw 21 through the movable sleeve 22, so that the sealing part 26 seals or opens the internal pipe of the pump body 1. The movement of the push plate 24 drives the connecting rod 261 and the sealing gate plate 263 to move out of the sealing sleeve 262 and fit with the internal pipe wall of the pump body 1 to achieve sealing and partitioning. The function of the sealing part 26 is to effectively seal the internal pipe of the pump body 1 when the partition mechanism 2 is operated to ensure the partition effect. The locking screw sleeve 25 is fixed with a handwheel. After the partition is completed, the locking screw sleeve 25 is rotated along the outer side of the screw 21 to fit with the movable sleeve 22 to adjust and fix the position of the partition mechanism 2 to maintain the partition effect. The limit plate of the screw sleeve ensures that the partition mechanism 2 stops at the appropriate position.

[0037] (2) When the diaphragm pump is drained and the diaphragm is replaced, after the partition mechanism 2 in the diaphragm pump effectively blocks the internal pipeline of the pump body 1, the control valve 42 is opened so that the liquid in the partition space in the pump body 1 can be discharged outward along the liquid guide tube 41. The discharged liquid first flows into the temporary storage tank 43 and then is discharged through the three-way pipe 44. At this time, according to maintenance requirements, the stop valve 47 of the discharge pipe 45 can be opened to discharge the liquid from the discharge pipe 45 to the outside for collection, and the stop valve 47 outside the reflux pipe 46 can also be opened to change the flow channel so that the liquid can flow back to the pump body 1. Repeated pumping is performed in this way, which can quickly discharge excess liquid in the diaphragm pump, keep the inside of the pump body 1 clean, and facilitate the disassembly, assembly, replacement and use of the diaphragm member 32. At the same time, when the diaphragm member 32 is disassembled and assembled, the diaphragm is fixed and disassembled through the structure of the disassembly flange 33 and the fastening bolts 35, so as to facilitate maintenance and replacement. When the disassembly flange 33 is connected to the pump body 1 and the fastening bolts 35 are inserted, the disassembly flange 33 is connected to the fastening bolts 35 through the locking nut 36 to make the disassembly flange 33 close to the pump body 1, and the pressure ring 34 is inserted into the pressure groove through the disassembly flange 33 through the fastening bolts 35 to limit the diaphragm member 32.
