An internal structure of a diaphragm pump heat insulator and a diaphragm pump

Abstract

The application discloses an internal structure of a diaphragm pump heat insulator, which comprises a shell, a guide rod, a slider and two elastic members. The shell is internally provided with a piston cavity, the guide rod is arranged in the piston cavity, the slider is slidably arranged on the guide rod, and the two elastic members are arranged at two ends of the guide rod. When the slider moves to the end of the guide rod, the slider compresses the elastic members to buffer the impact of the slider. The guide rod is arranged in the piston cavity, and the slider is slidably arranged on the guide rod, so that the slider can slide in the piston cavity. During the use of the diaphragm pump, the slider reciprocatingly slides along the guide rod. When the slider moves to the end of the guide rod, the slider compresses the elastic members to buffer the impact of the slider. Since the impact of the slider is buffered by the elastic members, the slider is prevented from being frequently subjected to violent impact and damaged, and the service life of the slider is prolonged.

Description

Technical Field

[0001] This application relates to the field of diaphragm pumps, specifically to the internal structure of a diaphragm pump heatsink and the diaphragm pump itself. Background Technology

[0002] In the high-pressure acid leaching process of laterite nickel ore, after the slurry is cleaned and thickened, it needs to be preheated before being injected into a high-pressure reactor for reaction. Usually, a diaphragm pump is used to transport the preheated slurry to the high-pressure reactor.

[0003] Existing diaphragm pumps, as described in patent application number CN202120767546.5, feature a freewheeling device installed on the piston guide rod inside the diaphragm pump's heat insulator. This freewheeling device reciprocates with the piston, providing isolation and heat insulation under the influence of the high-temperature slurry. However, when the freewheeling device reaches the end of the piston, it impacts the rod head bolt, causing damage to the inner sleeve of the freewheeling device (which is made of brittle, wear-resistant ceramic material). This damage subsequently affects other components, rendering the freewheeling device ineffective for heat insulation and reducing its service life.

[0004] Therefore, how to extend the service life of the ionizer is a technical problem that urgently needs to be solved.

[0005] Application content

[0006] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose an internal structure for a diaphragm pump heat exchanger, thereby solving the technical problem of how to extend the service life of the ionizer in the prior art.

[0007] To achieve the above-mentioned technical objectives, this application adopts the following technical solution:

[0008] On one hand, this application provides an internal structure for a diaphragm pump insulation device, which includes:

[0009] A housing containing a piston chamber;

[0010] A guide rod is mounted inside the piston cavity;

[0011] The detacher, which is slidably sleeved on the guide rod; and

[0012] Two elastic elements are disposed at both ends of the guide rod. When the ionizer moves to the end of the guide rod, the ionizer compresses the elastic elements to buffer the impact of the ionizer.

[0013] In some embodiments, the housing has a mounting portion, the elastic element includes a collar and a first spring, one end of the guide rod is fixed to the mounting portion, the collar is slidably sleeved on the guide rod, one end of the first spring is connected to the collar, and the other end is connected to the mounting portion, and the first spring has an elastic force that pushes the collar closer to the ionizer.

[0014] In some embodiments, the mounting portion has a mounting hole, and the guide rod passes through the mounting hole to fix the guide rod to the mounting portion.

[0015] In some embodiments, the collar is a ceramic collar.

[0016] In some embodiments, the elastic element includes a second spring sleeved on the guide rod, with one end connected to the housing. When the freewheel moves to the end of the guide rod, the freewheel compresses the second spring to cushion the impact of the freewheel.

[0017] In some embodiments, the housing further includes a support portion, one end of the guide rod is mounted on the support portion, and one end of the second spring is connected to the support portion.

[0018] In some embodiments, the ionizer includes an inner sleeve and an outer sleeve, the inner sleeve being fitted onto the guide rod, and the outer sleeve being fitted onto the outer periphery of the inner sleeve.

[0019] In some embodiments, the ionizer further includes two cushioning pads, which are respectively laid at both ends of the inner sleeve.

[0020] In some embodiments, the cushioning pad is a rubber cushioning pad.

[0021] A diaphragm pump includes the aforementioned internal structure of a diaphragm pump insulator.

[0022] The guide rod is mounted inside the piston chamber, and the freewheeling device is slidably sleeved on the guide rod, allowing the freewheeling device to slide within the piston chamber. During the operation of the diaphragm pump, the freewheeling device reciprocates along the guide rod. When the freewheeling device moves to the end of the guide rod, it compresses the elastic element to buffer the impact of the freewheeling device. Because the elastic element buffers the impact of the freewheeling device, it avoids frequent and severe impacts that could damage the freewheeling device, thus extending its service life.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0026] In order to solve the technical problem of how to extend the service life of the ionizer 300, this application provides an internal structure of a diaphragm pump heat shield that can buffer the impact of the ionizer 300, thereby extending the service life of the ionizer.

[0027] It should be noted that the internal structure of the diaphragm pump heat insulator in this application is used in, but not limited to, diaphragm pumps. For ease of explanation, this application only uses the application of the internal structure of the diaphragm pump heat insulator in a diaphragm pump as an example. The principle of the internal structure of the diaphragm pump heat insulator applied to other types of equipment is essentially the same as that applied to a diaphragm pump, and will not be elaborated here.

[0028] Please see Figure 1 , Figure 1 This is a schematic diagram of the internal structure of a diaphragm pump heat insulator in one embodiment of this application. The internal structure of the diaphragm pump heat insulator includes a housing 100, a guide rod 200, a free element 300, and two elastic elements 400. The housing 100 has a piston chamber 110. The guide rod 200 is mounted in the piston chamber 110. The free element 300 is slidably sleeved on the guide rod 200. The two elastic elements 400 are respectively disposed at both ends of the guide rod 200. When the free element 300 moves to the end of the guide rod 200, the free element 300 compresses the elastic elements 400 to buffer the impact of the free element 300.

[0029] In this embodiment, the guide rod 200 is mounted inside the piston chamber 110, and the freewheeling device 300 is slidably sleeved on the guide rod 200, allowing the freewheeling device 300 to slide within the piston chamber 110. During the operation of the diaphragm pump, the freewheeling device 300 slides back and forth along the guide rod 200. When the freewheeling device 300 moves to the end of the guide rod 200, it compresses the elastic element 400 to buffer the impact of the freewheeling device 300. Because the elastic element 400 buffers the impact of the freewheeling device 300, it avoids the freewheeling device 300 from being frequently subjected to severe impacts and thus prevents damage, extending the service life of the freewheeling device 300.

[0030] In some embodiments, the housing 100 has a mounting portion 120, the elastic element 400 includes a collar 410 and a first spring 420, one end of the guide rod 200 is fixed to the mounting portion 120, the collar 410 is slidably sleeved on the guide rod 200, one end of the first spring 420 is connected to the collar 410, and the other end is connected to the mounting portion 120, and the first spring 420 has a spring force that pushes the collar 410 closer to the detacher 300.

[0031] In this embodiment, when the detacher 300 reaches the end of the guide rod 200, the detacher 300 will press against the collar 410 and push the collar 410 to move. The movement of the collar 410 overcomes the elastic force of the first spring 420, thereby playing a role in buffering the detacher 300.

[0032] Any implementation that allows the guide rod 200 to be fixed on the mounting portion 120 is feasible. In some embodiments, the mounting portion 120 has a mounting hole 121, through which the guide rod 200 passes to fix the guide rod 200 to the mounting portion 120.

[0033] In this embodiment, since the guide rod 200 passes through the mounting hole 121, the guide rod 200 can be effectively prevented from moving radially by the limiting effect of the inner wall of the mounting hole 121, thereby playing the role of fixing the guide rod 200.

[0034] In some embodiments, the collar 410 is a ceramic collar 410.

[0035] In this embodiment, the ceramic collar 410 can withstand high temperatures, which can prevent the collar 410 from undergoing significant deformation due to thermal expansion and contraction in high-temperature working environments.

[0036] In some embodiments, the elastic element 400 includes a second spring 430, which is sleeved on the guide rod 200 and has one end connected to the housing 100. When the detacher 300 moves to the end of the guide rod 200, the detacher 300 compresses the second spring 430 to buffer the impact of the detacher 300.

[0037] In this embodiment, when the ionizer 300 moves to the end of the guide rod 200, the ionizer 300 compresses the second spring 430 to buffer the impact of the ionizer 300.

[0038] It is understood that the second spring 430 in the foregoing embodiments can be used as an alternative to the first spring 420 and the collar 410.

[0039] In some embodiments, the housing 100 further includes a support portion 130, one end of the guide rod 200 is mounted on the support portion 130, and one end of the second spring 430 is connected to the support portion 130.

[0040] In this embodiment, the support part 130 is used to fix the guide rod 200 on the one hand, and to support and fix the second spring 430 on the other hand.

[0041] In some embodiments, the detacher 300 includes an inner sleeve 310 and an outer sleeve 320, with the inner sleeve 310 fitted onto the guide rod 200 and the outer sleeve 320 fitted onto the outer periphery of the inner sleeve 310.

[0042] In this embodiment, the inner sleeve 310 is slidably sleeved on the guide rod 200, while the outer sleeve 320 is installed on the outer periphery of the inner sleeve 310. The inner sleeve 310 plays a supporting role, while the outer sleeve 320 is usually made of heat insulation material, thereby playing a heat insulation role.

[0043] Based on the above embodiments, in some embodiments, the ionizer 300 further includes two buffer pads 330, which are respectively laid at both ends of the inner sleeve 310.

[0044] In this embodiment, since the two buffer pads 330 are respectively laid at both ends of the inner sleeve 310, when the freewheel 300 moves to the end of the guide rod 200, not only can the elastic element 400 play a buffering role, but the buffer pads 330 can also play a buffering role, further improving the buffering effect.

[0045] Any flexible cushioning pad 330 that can provide cushioning is acceptable. In some embodiments, the cushioning pad 330 is a rubber cushioning pad 330.

[0046] In addition, this application also provides a diaphragm pump, including the internal structure of the diaphragm pump heatsink described above.

[0047] To better understand this application, the following is combined with... Figure 1 The technical solution of this application is described in detail below:

[0048] The guide rod 200 is mounted inside the piston chamber 110, and the freewheeling device 300 is slidably sleeved on the guide rod 200, allowing the freewheeling device 300 to slide within the piston chamber 110. During the operation of the diaphragm pump, the freewheeling device 300 slides back and forth along the guide rod 200. When the freewheeling device 300 reaches one end of the guide rod 200, it presses against the collar 410 and pushes the collar 410 to move. The movement of the collar 410 overcomes the elastic force of the first spring 420, thus buffering the freewheeling device 300. When the freewheeling device 300 moves to the other end of the guide rod 200, it compresses the second spring 430 to buffer the impact of the freewheeling device 300. Because the impact of the freewheeling device 300 is buffered by the elastic element 400, the freewheeling device 300 is prevented from being frequently subjected to severe impacts and thus its service life is extended.

[0049] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Any other corresponding changes and modifications made based on the technical concept of this application should be included within the scope of protection of the claims of this application.
