Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of recovery pumps, and in particular to a condensate recovery pump. Background Art

[0002] PTH high pressure condensate recovery pump is a pump used to handle high pressure condensate. This pump is usually designed to extract, transport or discharge condensate under high pressure conditions. PTH pumps usually have the ability to withstand high pressure to ensure that they can still operate effectively under high pressure environments.

[0003] The existing PTH high-pressure condensate recovery pump uses high-pressure driving air to drive the condensate flow in the pump body to achieve the transportation or discharge of condensate. When the high-pressure driving air enters the pump body, it directly impacts the condensate liquid surface, causing severe vibration and noise. In the case of long-term operation, severe vibration often causes failure of the pump's connecting pipes, liquid level gauges, fasteners and other components, causing the risk of leakage of high-pressure condensate, making the condensate recovery pump low in safety. Noise will have a negative impact on the health of workers. Utility Model Content

[0046] The utility model embodiment provides a condensate recovery pump, see Figure 1 As shown, including:

[0047] The pump body 1 has a first chamber 11 for storing condensed water, and also has a first opening 12 communicating with the first chamber 11;

[0048] A pump cover 2, provided at the first opening 12;

[0049] The connecting pipe 3 has a first end 31 and a second end 32 located at both sides of the connecting pipe 3 in the length direction thereof, wherein the first end 31 penetrates the pump cover 2 and at least partially extends into the first chamber 11, and the second end 32 is provided with an air intake control valve;

[0050] The silencer and vibration damper 4 is disposed at the first end portion 31 .

[0051] In the embodiment of the utility model, the high-pressure driving gas enters the first chamber 11 through the air intake control valve and the connecting pipe 3. The silencer 4 on the first end 31 prevents the high-pressure driving gas from directly impacting the condensate liquid level in the first chamber 11, thereby avoiding the severe vibration and noise caused by the direct impact, improving the safety of the condensate recovery pump in the embodiment of the utility model, and reducing the negative impact of vibration and noise on the health of workers.

[0052] In some embodiments of the present invention, optionally, see Figure 2 As shown, the silencer and vibration damper 4 comprises: a silencer and vibration damper tube body 41 and a sealing member 42;

[0053] The noise-absorbing and vibration-reducing tube body 41 has a third end portion 411 and a fourth end portion 412 disposed at two ends of the tube body in the longitudinal direction.

[0054] The third end 411 is connected to the first end 31 and the interface where the two are connected is sealed, and the pipe opening of the fourth end 412 is sealed by the sealing member 42;

[0055] The peripheral side wall of the fourth end portion 412 has a sound-absorbing and vibration-reducing through hole 43 .

[0056] In the embodiment of the utility model, after the high-pressure driving gas enters the silencer and vibration damping tube body 41 from the third end 411, since the fourth end 412 is sealed by the seal 42, the high-pressure driving gas is discharged into the first chamber 11 through the silencer and vibration damping through hole 43 on the peripheral wall of the fourth end 412. The high-pressure driving gas is converted from being discharged along the axial direction of the silencer and vibration damping tube body 41 to being discharged along the circumferential direction of the silencer and vibration damping tube body 41, so as to avoid the high-pressure driving gas directly impacting the condensate liquid surface in the first chamber 11, thereby avoiding the severe vibration and noise caused by the direct impact. The condensate recovery pump of the utility model embodiment has high safety and can reduce the negative impact of noise on the health of workers.

[0057] In some embodiments of the present invention, optionally, see Figure 1 and Figure 2 As shown, the sound-absorbing and vibration-damping tube body 41 is in a circular tube shape, the connecting tube 3 is in a circular tube shape, and the diameter of the sound-absorbing and vibration-damping tube body 41 is equal to the diameter of the connecting tube 3 .

[0058] In the embodiment of the utility model, the silencer and vibration damping tube body 41 is in a circular tubular shape, the connecting tube 3 is in a circular tubular shape, and the diameter of the silencer and vibration damping tube body 41 is equal to the diameter of the connecting tube 3, which is beneficial to the sealing between the third end 411 and the first end 31, and avoids leakage at the joint under the impact of long-term high-pressure driving gas.

[0059] In some embodiments of the present invention, optionally, see Figure 2 As shown, there are a plurality of noise-absorbing and vibration-reducing through holes 43 , and the plurality of noise-absorbing and vibration-reducing through holes 43 are arranged at intervals on the peripheral side wall of the second end portion 32 .

[0060] By arranging a plurality of silencer and vibration-reducing through holes 43 at intervals on the peripheral side wall of the second end portion 32, the high-pressure driving gas is depressurized, the problem of concentrated impact force of the high-pressure driving gas is further avoided, and the severe vibration and noise caused by direct impact are avoided, thereby improving the safety of the condensate recovery pump of the embodiment of the utility model and reducing the negative impact of vibration and noise on the health of workers.

[0061] In some embodiments of the present invention, optionally, see Figure 2 As shown, a plurality of sound-absorbing and vibration-reducing through holes 43 are arranged in an array and spaced apart on the peripheral side wall of the second end portion 32 .

[0062] Through the above-mentioned array arrangement, the embodiment of the utility model further avoids the problem of concentrated impact force of high-pressure driving gas, avoids severe vibration and noise caused by direct impact, improves the safety of the condensate recovery pump of the embodiment of the utility model, and reduces the negative impact of vibration and noise on the health of workers.

[0063] In some embodiments of the present invention, optionally, the array arrangement includes: M rows×N columns, or N rows×M columns; wherein M and N are both positive integers, and M:N=3:2.

[0064] It should be noted that the "rows" in the embodiment of the utility model are arranged along the circumferential direction of the sound-absorbing and vibration-damping tube body 41, and the "columns" are arranged along the axial direction of the sound-absorbing and vibration-damping tube body 41. Actual measurements have proved that the arrangement of multiple sound-absorbing and vibration-damping through holes 43 in the above array can improve the noise suppression effect and reduce vibration.

[0065] In some embodiments of the present invention, optionally, see Figure 2 As shown, the sum of the opening areas L of all the noise-absorbing and vibration-damping through holes 43 and the cross-sectional area K of the noise-absorbing and vibration-damping tube body 41 satisfy: L>K.

[0066] It should be noted that the opening area, i.e., the area formed on the circumferential side wall of the silencer and vibration damping tube body 41 by mapping the silencer and vibration damping through holes 43 along the radial direction of the silencer and vibration damping tube body 41. The cross-sectional area K of the silencer and vibration damping tube body 41, i.e., the cross-sectional area obtained by cutting the silencer and vibration damping tube body 41 with a cross section perpendicular to the axis of the silencer and vibration damping tube body 41. It can be understood that the sum of the opening area areas L of all the silencer and vibration damping through holes 43 and the cross-sectional area K of the silencer and vibration damping tube body 41 satisfy: L>K, which can ensure that the flux of all the silencer and vibration damping through holes 43 is greater than the flux of the silencer and vibration damping tube body 41, ensure that all the silencer and vibration damping through holes 43 relieve the pressure of the high-pressure driving gas, improve the safety of the condensate recovery pump of the embodiment of the utility model, and reduce the negative impact of vibration and noise on the health of the staff.

[0067] In some embodiments of the present invention, optionally, the shape of the sound-absorbing and vibration-reducing through hole 43 includes at least one of the following shapes: circular, triangular, rectangular, and square.

[0068] In practical applications, the hole shape may also include a keyway shape with semicircular arcs at both ends, that is, the user can use machine tools to process the silencer and vibration reduction tube body 41 to obtain the silencer and vibration reduction through hole 43. In other embodiments, the hole shape also includes a slit shape, that is, the user uses machining equipment to cut the tube wall of the silencer and vibration reduction tube body 41 to obtain the silencer and vibration reduction through hole 43.

[0069] In some embodiments of the present invention, optionally, see Figure 1As shown, the condensate recovery pump of the utility model embodiment also includes a first branch pipe section 321 and a second branch pipe section 322 arranged at the second end 32, and the first branch pipe section 321, the second branch pipe section 322, and the connecting pipe 3 are interconnected; the intake control valve is arranged on the first branch pipe section 321, and the second branch pipe section 322 is provided with an exhaust control valve.

[0070] By arranging the intake control valve and the exhaust control valve in different pipe sections, the cross-flow of intake and exhaust is avoided, thereby improving safety. It should be noted that when the high-pressure driving gas needs to be discharged into the first chamber 11, the intake control valve on the first branch pipe section 321 is opened, and the high-pressure driving gas enters the first chamber 11 through the first branch pipe section 321, the connecting pipe 3, and the silencer and vibration damper 4. During this process, the exhaust control valve arranged on the second branch pipe section 322 remains closed.

[0071] In some embodiments of the utility model, the junction of the pump cover 2 and the first opening 12 is optionally sealed by a flange assembly. The flange assembly has a simple structure, high reliability, and can achieve excellent sealing performance, and has been applied in large-scale industry. In the embodiment of the utility model, the junction of the pump cover 2 and the first opening 12 is sealed by a flange assembly, which can ensure the sealing between the pump cover 2 and the first opening 12 and help reduce manufacturing costs.
