Description

Technical Field

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

[0002] The axial flow high temperature sulfuric acid pump is a corrosion-resistant and high temperature resistant pump, which is mainly used for the transportation of high temperature sulfuric acid. The concentrated sulfuric acid pump is a new type of pump that applies the principle of modern magnetic mechanics and uses the magnetic transmission of permanent magnets to achieve contactless transmission of torque. That is, when the motor drives the outer rotor (i.e., outer magnetic steel) assembly to rotate, the magnetic lines of force pass through the isolation sleeve through the action of the magnetic field to drive the inner rotor (i.e., inner magnetic steel) assembly and the impeller to rotate synchronously. The flow-through parts are all made of fluoroplastics. It can transport corrosive media such as acids, alkalis, oxidants, etc. of any concentration (strength). Since the medium is enclosed in a 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. The only difference between them is the pump body form, and the internal structure is basically the same, mainly consisting of a pump casing, impeller, pump shaft, mounting base, etc.

[0004] However, since the mounting base on the existing horizontal axial flow sulfuric acid pump is generally welded on the pump casing, it cannot be flexibly adjusted according to the actual installation situation. Therefore, when installing it in some high-temperature concentrated sulfuric acid transportation sites where the ground cannot be installed, the ground needs to be reinforced, which is time-consuming and labor-intensive. If the sulfuric acid pump is directly installed on the wall, not only will the water outlet position be changed, but an elbow needs to be added to change the direction of the pipeline, which increases the installation cost. In addition, in some places with small spaces, it is impossible to add elbows, which greatly reduces the installation convenience of the device.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] like Figure 1-7 A high-efficiency axial-flow high-temperature concentrated sulfuric acid pump shown in the figure comprises a motor 1 and a pump head 2, a coupling 3 for connection is provided between the motor 1 and the pump head 2, a rotating ring 4 is fixedly connected to the side wall of the motor 1 and the outer wall of the pump head 2, a T-shaped circular groove 5 is provided 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 groove 5, a support frame 7 is fixedly connected to the side wall of the T-shaped block 6, a mounting plate 8 is fixedly connected to the side wall of the support frame 7, four mounting holes 9 are provided through the side wall of the mounting 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 mounting plate 8; The fixing mechanism includes a fixing rod 10, the outer walls of the motor 1 and the pump head 2 are fixedly connected with a fixing plate 11, the side walls of the fixing plate 11 are penetrated with three pairs of fixing holes 12, a pair of fixing frames 13 are provided on the front side of the mounting plate 8, and the fixing frame 13 is arranged on the front side of the mounting hole 9 close to the side of the fixing plate 11, and a mounting cavity 14 is provided inside the mounting plate 8 and at a position corresponding to the fixing frame 13, the fixing rod 10 is slidably connected to the inner side of the mounting cavity 14 and penetrates the side wall of the mounting plate 8, an adjustment slot 15 is provided on the front side of the fixing rod 10, and the adjustment slot 15 is inclined near the side of the fixing hole 12, and the rear side of the fixing frame 13 is fixedly connected with a straight The rod 16 is arranged to penetrate the inner side of the installation cavity 14, and a right-angle block 17 that fits the inclined surface of the adjustment groove 15 is fixedly connected to the rear side of the straight rod 16. A plurality of upper springs 18 are fixedly connected between the front side of the installation plate 8 and the fixing frame 13. The side walls of the fixing rod 10 are fixedly connected with fixing heads 19 for inserting into the fixing holes 12. The inner side of the installation cavity 14 and the side walls of the fixing rod 10 are fixedly connected with lower springs 20. The fixing heads 19 are arranged in a conical shape. By arranging the fixing heads 19 in a conical shape, the tighter the bolts are tightened, the more the fixing heads 19 are inserted, and the larger the inclined surface of the fixing hole 12 is squeezed, the tighter the fixing is. The positioning mechanism includes a positioning spring 24, a slide groove 22 is provided on the side wall of the support frame 7, a positioning rod 23 is slidably connected to the inner side of the slide groove 22 and penetrates the side wall of the T-shaped block 6, a plurality of positioning holes 25 are provided on the inner side of the T-shaped annular groove 5, the positioning spring 24 is fixedly connected between the inner side of the slide groove 22 and the side wall of the positioning rod 23, and a push plate 26 is fixedly connected to the outer wall of the positioning rod 23; When installing the sulfuric acid pump, firstly, the motor 1 and the pump head 2 are lifted by the hook 21. When the sulfuric acid pump cannot be installed on the ground and needs to be installed on the wall, first pull the push plate 26 outward to drive the positioning rod 23 to slide 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, the mounting plate 8 is rotated to drive the T-block 6 to rotate in the T-shaped circular groove 5 through the support frame 7. After the mounting plate 8 is rotated to the installation position, the push plate 26 can be loosened, and then the positioning rod 23 is pushed to be inserted into the corresponding positioning hole 25 by the elastic force of the positioning spring 24 to preliminarily fix the position of the mounting plate 8. Then, an expansion nut is installed at the position corresponding to the mounting hole 9 on the installation wall, and then the bolts are sequentially passed through the mounting hole 9 and threadedly installed in the expansion nut. At the same time, the rotation of the bolt will squeeze the fixing frame 13 to slide, and at the same time compress the upper spring 18, thereby driving the straight rod 16 and the right-angle block 17 to slide, so that the inclined surface of the right-angle block 17 squeezes the inclined surface of the adjusting groove 15, thereby squeezing the fixing rod 10 outward, and at the same time stretching the lower spring 20, so that the fixing head 19 is inserted into the fixing hole 12. Since the fixing head 19 is set in a conical shape, the tighter the bolt is tightened, the more the fixing head 19 is inserted into the fixing hole 12, and the larger the inclined surface of the fixing hole 12 is squeezed. Since the fixing plate 11 is fixed to the motor 1 and the pump head 2 respectively, the mounting plate 8 is fixed to the motor 1 and the pump head 2 more tightly, so that not only the installation position of the sulfuric acid pump can be flexibly adjusted, but also the rotation position of the mounting plate 8 can be fixed while fixing the sulfuric acid pump mounting plate 8, without multiple fixations, thereby improving the convenience of device installation.

[0022] In order to facilitate the installation of the sulfuric acid pump, the motor 1 and the top of the pump head 2 are fixedly connected with a hook 21. Since the overall volume of the sulfuric acid pump is large and the weight is heavy, the setting of the hook 21 makes it easy to lift the sulfuric acid pump with a small crane for installation.

[0023] In order to adjust the height of the mounting plate 8 after drilling, the lengths of the four mounting holes 9 and the inner sides of the fixing frame 13 are lengthened. By lengthening the mounting holes 9 and the fixing frame 13, the positions of the bolts on the mounting holes 9 can be adjusted, and then the mounting plate 8 can be slid up and down to adjust the docking height between the motor 1 and the pump head 2, which is flexibly applicable to different installation situations.

[0024] In order to be able to flexibly adjust the horizontality of the mounting plate 8 according to the unevenness of the installation position, a circular groove 27 is formed through the side wall of the mounting plate 8, an adjusting block 28 is slidably connected to the inner side of the circular groove 27, a threaded groove 29 is formed through the front side of the adjusting block 28, a screw rod 30 is threadedly connected to the inner side of the threaded groove 29, a hexagonal hole 36 is formed on the front side of the screw rod 30, a stop 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; During the installation process, when the installation position of the mounting plate 8 is tilted, resulting in the coaxiality of the motor 1 and the pump head 2 not being at the same level after docking, first unscrew a part of the fastening bolts, then rotate the adjustment block 28 to rotate in the circular groove 27, and then rotate the stop block 31 to the adjustment position, then use an Allen wrench to insert it into the hexagonal hole 36, and then rotate the Allen wrench to drive the screw rod 30 to rotate. Since the screw rod 30 is threadedly connected to the thread groove 29, the screw rod 30 is spirally moved backward, and then the stop block 31 is pushed to contact the wall of the installation position, and then the bolts are tightened to fix the mounting plate 8 on the wall, and then measurements are taken until the mounting plate 8 is adjusted to a horizontal state.

[0025] In order to increase the number of adjustment blocks 28 according to the adjustment situation, a limiting groove 32 is provided inside the circular groove 27, and a limiting block 33 adapted to the limiting groove 32 is fixedly connected to the side wall of the adjustment block 28, and a pair of sockets 34 are provided on the front side of the mounting plate 8 and located at the limiting groove 32; When the installation position of the mounting plate 8 has multiple uneven places and the number of adjustment blocks 28 needs to be increased, first insert the limit block 33 of the side wall of the added adjustment block 28 into the limit groove 32 from the socket 34, and then rotate the adjustment block 28 in the circular groove 27. Rotate the stop block 31 to the position that needs to be adjusted and then rotate the screw 30 for adjustment. Then, it can be flexibly adjusted according to the actual installation situation, thereby improving the flexibility of the device.
