Description

Technical Field

[0001] This application relates to the field of acetylene generation equipment, and more particularly, to a self-priming tank and a pumping system for a circulating water pump of an acetylene generator. Background Art

[0002] An acetylene generator uses calcium carbide and water to react to produce acetylene gas. Generally, a water pump is required to suck and circulate water for recycling.

[0003] In actual production, the circulating water used in the reaction of calcium carbide and water contains a large amount of Ca(OH)2. This aqueous solution will corrode the check valve in the water pump, resulting in the failure of the check valve, the inability of the water pump to self-prime, and ultimately the inability to use the water pump. At the same time, during the circulation of water, the impeller and housing of the water pump are severely scaled, causing damage to the water pump and affecting the production of acetylene gas. Summary of the Utility Model

[0004] The purpose of this application is to provide a self-priming tank and a pumping system for a circulating water pump of an acetylene generator to improve the technical problem that the current circulating water contains a large amount of Ca(OH)2, which easily causes severe scaling or damage to the water pump.

[0005] In a first aspect, an embodiment of this application provides a self-priming tank for a circulating water pump of an acetylene generator, including: a tank body, a top cover is detachably connected to the top of the tank body, a filter plate is detachably arranged near one end of the top cover inside the tank body, and the outer diameter of the filter plate is adapted to the inner diameter of the tank body; a water inlet pipe is arranged inside the tank body, and the water outlet end of the water inlet pipe extends above the filter plate, a water outlet is arranged on the side wall of the tank body, the water outlet is located below the filter plate, and the water outlet is connected to the water inlet of the pump.

[0006] In the above implementation process, this application detachably connects the top cover to the top of the tank body, and detachably arranges the filter plate near one end of the top cover inside the tank body. The water outlet end of the water inlet pipe extends above the filter plate. After the circulating water enters from the water inlet pipe and is discharged from the water outlet end above the filter plate, the sundries in the water are intercepted on the filter plate, and most of the scaling also occurs above the filter plate after a long time, reducing the influence of scaling and sundries on the pump. And when there are too many sundries or too much scaling on the filter plate, after removing the top cover, the filter plate can be directly removed for cleaning or replacement.

[0007] In a possible implementation, a fixing ring is circumferentially arranged on the inner wall of the tank body near one end of the top cover, and the filter plate is detachably connected to the fixing ring.

[0008] This application circumferentially arranges a fixing ring on the inner wall of the tank body to facilitate the fixed installation of the filter plate.

[0009] In a possible implementation, through holes are provided on the filter plate, and the aperture of the through holes is adapted to the outer diameter of the water inlet pipe; the water inlet pipe extends into the tank from the bottom of the tank, is arranged along the height of the tank and passes through the through holes, so that the water outlet end of the water inlet pipe extends out of the filter plate to above the filter plate.

[0010] In this application, by providing through holes on the filter plate with an aperture adapted to the outer diameter of the water inlet pipe, the water outlet end of the water inlet pipe can extend out of the filter plate to above the filter plate, and gaps are avoided, preventing debris from leaking under the filter plate through the gaps. At the same time, the water inlet pipe extends into the tank from the bottom of the tank, is arranged along the height of the tank and passes through the through holes, so that the water outlet end of the water inlet pipe extends out of the filter plate to a certain height above the filter plate. This can keep a certain amount of water in the tank all the time, which can be used as pilot water to facilitate starting the water circulation, and the water outlet end of the water inlet pipe is higher than the water surface to prevent liquid backflow.

[0011] In a possible implementation, a support ring is circumferentially arranged on the outer wall of the water inlet pipe, and the upper surface of the support ring supports the area of the filter plate close to the water inlet pipe.

[0012] In this application, by circumferentially arranging a support ring on the outer wall of the water inlet pipe, a certain support can be provided for the area of the filter plate close to the water inlet pipe, avoiding deformation of the filter plate over a long time and generating gaps.

[0013] In a possible implementation, the distance between the filter plate and the top cover is not greater than 1 / 2 of the height of the tank.

[0014] In this application, by arranging the filter plate at one end close to the top cover, it is more convenient to clean the debris on the filter plate and also convenient to disassemble the filter plate.

[0015] In a possible implementation, the height by which the water outlet end of the water inlet pipe protrudes from the filter plate is not less than 5 cm, and the distance between the water outlet end and the top cover is not less than 10 cm.

[0016] In this application, by setting the water outlet end of the water inlet pipe to protrude from the filter plate by a certain height, there is a certain buffer distance after the water is discharged, so that most of the scaling occurs above the filter plate to a greater extent, reducing the impact of scaling on the pump. At the same time, it avoids water splashing directly onto the top cover.

[0017] In a possible implementation, a liquid addition port is provided on the side wall of the tank, and the liquid addition port is located above the filter plate.

[0018] In this application, by providing a liquid addition port above the filter plate, water can be added from the liquid addition port to supplement the water in the tank; acid solution can also be added from the liquid addition port to neutralize the scaling above the filter plate.

[0019] In a possible implementation, the position of the liquid addition port is at least 3 cm higher than the filter plate.

[0020] In this application, the position of the liquid filling port is set at a certain distance higher than the filter plate, which is conducive to maximizing the contact and neutralization with the scale on the filter plate and in the tank when adding acid liquid from the liquid filling port, so as to reduce the scale.

[0021] In a possible implementation manner, an observation hole is provided on the top cover, and a transparent cover is provided on the observation hole.

[0022] In this application, by providing an observation hole on the top cover, the debris and scale on the filter plate can be checked at any time, which is convenient for cleaning or replacing the filter plate in time.

[0023] In a second aspect, an embodiment of this application provides an acetylene generator circulating pumping system, which includes a pump and the self-priming tank provided in the first aspect. The water outlet of the self-priming tank is connected to the water inlet of the pump.

[0024] The self-priming tank provided in this application can intercept scale or debris, reduce serious scaling or damage of the water pump, so that the pumping system including the self-priming tank can reduce the shutdown or damage of the pump and avoid affecting the generation of acetylene gas.

[0034] Embodiment 1

[0035] The present application aims to improve the technical problem that a large amount of Ca(OH)₂ in the existing circulating water easily causes serious scaling or damage to the water pump, and proposes a self-priming tank for a circulating water pump of an acetylene generator, as Figure 1As shown in the figure, it includes: a tank body 1, a top cover 11 is detachably connected to the top of the tank body 1, a filter plate 2 is detachably arranged at one end of the tank body 1 close to the top cover 11, and the outer diameter of the filter plate 2 is adapted to the inner diameter of the tank body 1; a water inlet pipe 3 is arranged in the tank body 1, and the water outlet end of the water inlet pipe 3 extends above the filter plate 2 to the upper side of the filter plate 2. An outlet 12 is arranged on the side wall of the tank body 1, the outlet 12 is located below the filter plate 2, and the outlet 12 is connected to the water inlet 41 of the pump 4.

[0036] In this application, the top cover 11 is detachably connected to the top of the tank body 1, and the filter plate 2 is detachably arranged at one end of the tank body 1 close to the top cover 11. The water outlet end of the water inlet pipe 3 extends above the filter plate 2 to the upper side of the filter plate 2. After the circulating water enters from the water inlet pipe 3, it is discharged from the water outlet end to the upper side of the filter plate 2, so that the sundries in the water are intercepted on the filter plate 2, and most of the scaling also occurs above the filter plate 2 after a long time, reducing the impact of scaling and sundries on the pump 4; and when there are too many sundries or too much scaling on the filter plate 2, after removing the top cover 11, the filter plate 2 can be directly removed for cleaning or replacement.

[0037] In some embodiments, a fixing ring 13 is circumferentially arranged on the inner wall of the tank body 1 at one end close to the top cover 11, and the filter plate 2 is detachably connected to the fixing ring 13. The fixing ring 13 circumferentially arranged on the inner wall of the tank body 1 facilitates the fixed installation of the filter plate 2. Exemplarily, the filter plate 2 and the fixing ring 13 can be detachably connected by bolts, or other methods (such as pins) can be used for detachable connection.

[0038] In some embodiments, through holes are formed in the filter plate 2, and the aperture of the through holes is adapted to the outer diameter of the water inlet pipe 3. By forming through holes with an aperture adapted to the outer diameter of the water inlet pipe 3 on the filter plate 2, the water outlet end of the water inlet pipe 3 can extend above the filter plate 2 to the upper side of the filter plate 2, and gaps are avoided, preventing sundries from leaking below the filter plate 2 through the gaps.

[0039] In some embodiments, the water inlet pipe 3 extends into the tank body 1 from the bottom of the tank body 1, is arranged along the height of the tank body 1 and passes through the through holes, so that the water outlet end of the water inlet pipe 3 extends above the filter plate 2 to a certain height. A certain amount of water can be kept in the tank body 1 all the time, which can be used as leading water to facilitate the start of the water circulation, and the water outlet end of the water inlet pipe is higher than the water surface to prevent liquid backflow.

[0040] In some embodiments, a support ring 31 is circumferentially arranged on the outer wall of the water inlet pipe 3, and the upper surface of the support ring 31 supports the area of the filter plate 2 close to the water inlet pipe 3. Circumferentially arranging the support ring 31 on the outer wall of the water inlet pipe 3 can provide certain support for the area of the filter plate 2 close to the water inlet pipe 3, preventing the filter plate 2 from deforming and generating gaps after long-term use. It can be understood that the bottom wall of the area of the filter plate 2 close to the water inlet pipe 3 is in close contact with the top wall of the support ring 31 to prevent the appearance of gaps through which debris can pass. Exemplarily, the area of the filter plate 2 close to the water inlet pipe 3 and the support ring 31 can be directly placed in contact for support, or can be detachably connected by bolts or other means.

[0041] In some embodiments, the distance between the filter plate 2 and the top cover 11 is not greater than 1 / 2 of the height of the tank body 1. Arranging the filter plate 2 at one end close to the top cover 11 makes it more convenient to clean the debris on the filter plate 2 and also facilitates the disassembly of the filter plate 2.

[0042] Exemplarily, the distance between the filter plate 2 and the top cover 11 can be, but is not limited to, 1 / 3, 1 / 4, 1 / 5 of the height of the tank body 1. The closer the filter plate 2 is arranged to the top cover 11, the more convenient it is to clean the debris on the filter plate 2 or disassemble the filter plate 2.

[0043] In some embodiments, the height by which the water outlet end of the water inlet pipe 3 protrudes from the filter plate 2 is not less than 5 cm, and the distance between the water outlet end and the top cover 11 is not less than 10 cm. Exemplarily, the height by which the water outlet end of the water inlet pipe 3 protrudes from the filter plate 2 can be, but is not limited to, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm. The distance between the water outlet end and the top cover 11 can be, but is not limited to, 10 cm, 15 cm, 20 cm, 25 cm, 30 cm. The water outlet end of the water inlet pipe 3 protrudes from the filter plate 2 by a certain height, so that there is a certain buffer distance after the water is discharged, to maximize the scaling above the filter plate 2 and filtration, reducing the impact of scaling on the pump 4. At the same time, there is a certain distance between the water outlet end and the top cover 11 to prevent the water from splashing directly onto the top cover 11 when discharged from the water outlet end.

[0044] In some embodiments, a liquid adding port 14 is provided on the side wall of the tank body 1, and the liquid adding port 14 is located above the filter plate 2. Providing the liquid adding port 14 above the filter plate 2 allows water to be added from the liquid adding port 14 to supplement water in the tank body 1; acid solution can also be added from the liquid adding port 14 to neutralize the scaling above the filter plate 2. It can be understood that two liquid adding ports 14 can also be provided on the side wall of the tank body 1, one for adding water and the other for adding acid solution.

[0045] In some embodiments, the position of the liquid filling port 14 is at least 3 cm higher than that of the filter plate 2. Exemplarily, the position of the liquid filling port 14 can be, but is not limited to, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, or 8 cm higher than that of the filter plate 2. The liquid filling port 14 being at a certain distance higher than the filter plate 2 is conducive to the acid solution added from the liquid filling port 14 coming into contact and neutralizing with the scale in the tank 1 on the filter plate 2 to a greater extent, so as to reduce the scale.

[0046] In some embodiments, an observation hole 111 is provided on the top cover 11, and a transparent cover is provided on the observation hole 111. Through the observation hole 111 provided on the top cover 11, the debris and scale on the filter plate 2 can be checked at any time, facilitating the timely cleaning or replacement of the filter plate 2.

[0047] In some embodiments, a drain port 15 is provided at the bottom of the tank 1, and a vent port 112 is provided on the top cover 11. When cleaning the entire tank 1, it is convenient to drain the water in the tank 1 from the drain port 15; by providing the vent port 112 on the top cover 11, it is convenient to discharge the gas in the tank 1.

[0048] Embodiment 2

[0049] This embodiment provides an acetylene generator circulating pumping system, as Figure 1 shown, which includes a pump 4 and the self-priming tank provided in the first aspect, and the water outlet 12 of the self-priming tank is connected to the water inlet of the pump 4.

[0050] The self-priming tank provided in Embodiment 1 of this application can intercept scale or debris, reduce severe scaling or damage of the water pump, so that the pumping system including this self-priming tank can reduce the shutdown or damage of the pump 4 and avoid affecting the generation of acetylene gas.

[0051] During use, the water inlet end of the water inlet pipe 3 extends into the circulating water tank. When starting the pump 4 to pump water, the water in the circulating water tank enters from the water inlet end of the water inlet pipe 3, is conveyed to the water outlet end of the water inlet pipe 3 and discharged. The water is discharged above the filter plate 2, the water flow passes through the filter plate 2 and flows to the lower part of the filter plate 2, and then flows to the water inlet 41 of the pump 4 through the water outlet 12 for circulating conveyance. When the water flows through the filter plate 2, the debris in the water is intercepted on the filter plate 2, and most of the scale formed over a long time also forms above the filter plate 2, thereby reducing the influence of scale and debris on the pump 4; and when there is too much debris or scale on the filter plate 2, after removing the top cover 11, the filter plate 2 can be directly removed for cleaning or replacement. At the same time, the water inlet pipe 3 extends into the tank 1 from the bottom of the tank 1 and is arranged along the height of the tank 1, so that the water outlet end of the water inlet pipe 3 protrudes a certain height above the filter plate 2, which can keep a certain amount of water in the tank 1 all the time, which can be used as a water guide to facilitate the start of the water cycle, and the water outlet end of the water inlet pipe is higher than the water surface to prevent liquid backflow.

[0052] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
