Description

Technical Field

[0001] The present invention relates to the technical field of concentrated sulfuric acid pumps, and particularly to a high-efficiency axial-flow high-temperature concentrated sulfuric acid pump. Background Art

[0002] Axial-flow high-temperature sulfuric acid pumps are pumps with corrosion resistance and high temperature resistance, mainly used for the transportation of high-temperature sulfuric acid. Concentrated sulfuric acid pumps are a new type of pump that applies the principle of modern magnetism and uses the magnetic drive of permanent magnets to achieve contactless transmission of torque. That is, when the motor drives the outer rotor (i.e., the outer magnetic steel) assembly to rotate, through the action of the magnetic field, the magnetic force lines pass through the isolation sleeve to drive the inner rotor (i.e., the inner magnetic steel) assembly and the impeller to rotate synchronously. All flow-through components are made of fluoroplastics and can transport corrosive media such as acids, alkalis, and oxidants with any concentration (strength). Since the medium is enclosed in the stationary isolation sleeve, the purpose of pumping the medium without leakage is achieved.

[0003] Axial-flow pumps can be divided into three types according to the installation position of the pump shaft: vertical, inclined, and horizontal. They only differ in the form of the pump body, and their internal structures are basically the same. They mainly consist of a pump casing, an impeller, a pump shaft, a mounting base, etc.

[0004] However, since the mounting seat on the existing horizontal axial-flow sulfuric acid pump is generally welded to the pump casing and cannot be flexibly adjusted according to the actual installation situation, when installing in some high-temperature concentrated sulfuric acid transportation sites where the ground cannot be installed, it is also necessary to reinforce the ground additionally, which is time-consuming and laborious. If the sulfuric acid pump is directly installed on the wall, not only will the position of the water outlet be changed, and elbows need to be added additionally to change the pipeline direction, which will increase the installation cost, but also elbows cannot be added in some places with narrow space, thus greatly reducing the installation convenience performance of the device.

[0005] Therefore, a high-efficiency axial-flow high-temperature concentrated sulfuric acid pump is proposed to solve the problem of being unable to be flexibly adjusted according to the installation site. Summary of the Invention

[0006] The purpose of the present invention is to solve the deficiencies in the background art and propose a high-efficiency axial-flow high-temperature concentrated sulfuric acid pump.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is: a high-efficiency axial-flow high-temperature concentrated sulfuric acid pump, including a motor and a pump head. A coupling for connection is provided between the motor and the pump head. Rotating rings are fixedly connected to the side wall of the motor and the outer wall of the pump head. A T-shaped circular ring groove is formed on the outer wall of the rotating ring. A T-shaped block is slidably connected to the inner side of the T-shaped circular ring groove. A support frame is fixedly connected to the side wall of the T-shaped block. An installation plate is fixedly connected to the side wall of the support frame. Four installation holes are formed through the side wall of the installation plate. A positioning mechanism is provided between the support frame and the rotating ring. A fixing mechanism is provided on the installation plate;

[0008] The fixing mechanism includes a fixing rod. Fixing plates are fixedly connected to the outer walls of both the motor and the pump head. Three pairs of fixing holes are respectively formed through the side walls of the fixing plates. A pair of fixing frames are arranged on the front side of the mounting plate, and the fixing frames are arranged in front of the mounting holes on the side close to the fixing plates. Mounting cavities are respectively formed inside the mounting plate at positions corresponding to the fixing frames. The fixing rod is slidably connected to the inner side of the mounting cavity and penetrates through the side wall of the mounting plate. An adjusting groove is formed on the front side of the fixing rod, and the adjusting groove is inclined towards the side close to the fixing holes. Straight rods are fixedly connected to the rear sides of the fixing frames and penetrate through the inner sides of the mounting cavities. Right-angle blocks that are in fit with the inclined surfaces of the adjusting grooves are fixedly connected to the rear sides of the straight rods. A plurality of upper springs are fixedly connected between the front side of the mounting plate and the fixing frames. Fixing heads for inserting into the fixing holes are fixedly connected to the side walls of the fixing rods.

[0009] In the above technical solution, further, lower springs are fixedly connected between the inner sides of the mounting cavities and the side walls of the fixing rods, and the fixing heads are arranged in a conical shape.

[0010] In the above technical solution, further, hooks are fixedly connected to the tops of both the motor and the pump head.

[0011] In the above technical solution, further, the positioning mechanism includes a positioning spring. A sliding groove is formed in the side wall of the support frame. A positioning rod is slidably connected to the inner side of the sliding groove and penetrates through the side wall of the T-shaped block. A plurality of positioning holes are formed inside the T-shaped circular groove. The positioning spring is fixedly connected between the inner side of the sliding groove and the side wall of the positioning rod. A push plate is fixedly connected to the outer wall of the positioning rod.

[0012] In the above technical solution, further, the lengths of the four mounting holes and the inner sides of the fixing frames are all extended.

[0013] In the above technical solution, further, a circular groove is formed through the side wall of the mounting plate. An adjusting block is slidably connected to the inner side of the circular groove. A threaded groove is formed through the front side of the adjusting block, and a screw rod is threadedly connected to the inner side of the threaded groove.

[0014] In the above technical solution, further, a limiting groove is formed inside the circular groove.

[0027] In order to more clearly understand the above-mentioned objects, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] In the following description, many specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0029] As Figure 1-7 shown, an efficient axial-flow high-temperature concentrated sulfuric acid pump includes a motor 1 and a pump head 2. A coupling 3 for connection is provided between the motor 1 and the pump head 2. Rotating rings 4 are fixedly connected to the side wall of the motor 1 and the outer wall of the pump head 2. A T-shaped circular ring groove 5 is formed on the outer wall of the rotating ring 4. A T-shaped block 6 is slidably connected to the inner side of the T-shaped circular ring groove 5. A support frame 7 is fixedly connected to the side wall of the T-shaped block 6. An installation plate 8 is fixedly connected to the side wall of the support frame 7. Four installation holes 9 are formed through the side wall of the installation plate 8. A positioning mechanism is provided between the support frame 7 and the rotating ring 4, and a fixing mechanism is provided on the installation plate 8;

[0030] The fixing mechanism includes fixing rods 10. Fixing plates 11 are fixedly connected to the outer walls of the motor 1 and the pump head 2. Three pairs of fixing holes 12 are formed through the side walls of the fixing plates 11. A pair of fixing frames 13 are provided on the front side of the installation plate 8, and the fixing frames 13 are arranged in front of the installation holes 9 close to the fixing plates 11. Installation cavities 14 are formed inside the installation plate 8 at positions corresponding to the fixing frames 13. The fixing rods 10 are slidably connected to the inner side of the installation cavities 14 and penetrate through the side walls of the installation plate 8. Adjustment grooves 15 are formed on the front sides of the fixing rods 10, and the adjustment grooves 15 are inclined towards the fixing holes 12. Straight rods 16 are fixedly connected to the rear sides of the fixing frames 13 and penetrate through the inner sides of the installation cavities 14. Right-angled blocks 17 that are in fit with the inclined surfaces of the adjustment grooves 15 are fixedly connected to the rear sides of the straight rods 16. A number of upper springs 18 are fixedly connected between the front side of the installation plate 8 and the fixing frames 13. Fixing heads 19 for inserting into the fixing holes 12 are fixedly connected to the side walls of the fixing rods 10. Lower springs 20 are fixedly connected between the inner sides of the installation cavities 14 and the side walls of the fixing rods 10. The fixing heads 19 are conically arranged. By arranging the fixing heads 19 in a conical shape, the tighter the bolt is screwed, the more the fixing heads 19 are inserted, and thus the greater the extrusion of the inclined surfaces of the fixing holes 12, and the tighter the fixation;

[0031] The positioning mechanism includes a positioning spring 24. A sliding groove 22 is formed on the side wall of the support frame 7. A positioning rod 23 is slidably connected to the inner side of the sliding groove 22 and penetrates through the side wall of the T-shaped block 6. A number of positioning holes 25 are formed in the inner side of the T-shaped circular ring groove 5. The positioning spring 24 is fixedly connected between the inner side of the sliding groove 22 and the side wall of the positioning rod 23. A push plate 26 is fixedly connected to the outer wall of the positioning rod 23;

[0032] When installing the sulfuric acid pump, first lift the motor 1 and the pump head 2 by the hook 21. When the ground installation is not possible and the sulfuric acid pump needs to be installed on the wall, first pull the push plate 26 outwards to drive the positioning rod 23 out of the positioning hole 25, and at the same time compress the positioning spring 24 to release the fixation of the rotation position of the mounting plate 8. Then rotate the mounting plate 8 to drive the T-shaped block 6 to rotate in the T-shaped circular ring groove 5 through the support frame 7. After rotating the mounting plate 8 to the installation position, the push plate 26 can be released. Subsequently, the positioning rod 23 is pushed into the corresponding positioning hole 25 by the elastic force of the positioning spring 24 to initially fix the position of the mounting plate 8. Then, expansion nuts are drilled at the positions corresponding to the mounting holes 9 on the installation wall, and the bolts are sequentially threaded through the mounting holes 9 and installed in the expansion nuts;

[0033] At the same time, through the rotation of the bolt, the fixed frame 13 will be squeezed to slide, and at the same time the upper spring 18 will be compressed, driving the straight rod 16 and the right-angle block 17 to slide accordingly. The inclined surface of the right-angle block 17 squeezes the inclined surface of the adjustment groove 15, so as to squeeze the fixing rod 10 outwards, and at the same time stretch the lower spring 20, so that the fixing head 19 is inserted into the fixing hole 12. Due to the conical setting of the fixing head 19, the tighter the bolt is screwed, the more the fixing head 19 is inserted into the fixing hole 12, and thus the inclined surface of the fixing hole 12 is squeezed more. And because the fixing plate 11 is fixed on the motor 1 and the pump head 2 respectively, the mounting plate 8 is fixed more tightly to the motor 1 and the pump head 2. Therefore, not only can the installation position of the sulfuric acid pump be flexibly adjusted, but also the rotation position of the mounting plate 8 can be fixed while fixing the mounting plate 8 of the sulfuric acid pump, without multiple fixations, improving the convenience of device installation.

[0034] To facilitate the installation of the sulfuric acid pump, hooks 21 are fixedly connected to the tops of both the motor 1 and the pump head 2. Since the overall volume of the sulfuric acid pump is large and the weight is heavy, the setting of the hooks 21 facilitates lifting the sulfuric acid pump by a small crane for installation during installation.

[0035] To adjust the height of the mounting plate 8 after drilling, the lengths of the four mounting holes 9 and the inner side of the fixed frame 13 are both lengthened. By lengthening the mounting holes 9 and the fixed frame 13, the position of the bolt on the mounting hole 9 can be adjusted, and then the mounting plate 8 can be slid up and down to adjust the docking height of the motor 1 and the pump head 2, which is flexibly applicable to different installation situations.

[0036] In order to be able to flexibly adjust the levelness of the mounting plate 8 according to the uneven installation position, a circular groove 27 is penetrated through the side wall of the mounting plate 8. A regulating block 28 is slidably connected inside the circular groove 27. A threaded groove 29 is penetrated through the front side of the regulating block 28. A screw rod 30 is threadedly connected inside the threaded groove 29. An internal hexagonal hole 36 is formed in the front side of the screw rod 30. A resisting block 31 is rotatably connected to the rear side of the screw rod 30. And a side rod 35 is fixedly connected between the side wall of the support frame 7 and the side wall of the mounting plate 8.

[0037] During the installation process, when the installation position of the mounting plate 8 is inclined, resulting in the coaxiality not being on the same level after the motor 1 and the pump head 2 are docked, first screw out a part of the tightened bolt, then rotate the regulating block 28 to rotate in the circular groove 27, and then rotate the resisting block 31 to the adjustment position. Subsequently, insert an internal hexagonal wrench into the internal hexagonal hole 36, and then rotate the internal hexagonal wrench to drive the screw rod 30 to rotate. Since the screw rod 30 is threadedly connected with the threaded groove 29, the screw rod 30 spirally moves backward, thereby pushing the resisting block 31 to abut against the wall surface of the installation position. Then tighten the bolt to fix the mounting plate 8 on the wall surface, and then measure until the mounting plate 8 is adjusted to a horizontal state.

[0038] In order to be able to increase the number of regulating blocks 28 according to the adjustment situation, a limiting groove 32 is formed inside the circular groove 27. A limiting block 33 adapted to the limiting groove 32 is fixedly connected to the side wall of the regulating block 28. A pair of sockets 34 are formed in the front side of the mounting plate 8 and at the position of the limiting groove 32.

[0039] When there are multiple unevennesses in the installation position of the mounting plate 8 and the number of regulating blocks 28 needs to be increased, first insert the limiting block 33 on the side wall of the added regulating block 28 into the limiting groove 32 from the socket 34, then rotate the regulating block 28 to rotate in the circular groove 27, rotate the resisting block 31 to the position where adjustment is needed, and then rotate the screw rod 30 for adjustment, so as to be flexibly adjusted according to the actual installation situation and improve the flexibility of the device.
