Background

In industrial production, a plurality of high-temperature waste liquid is often generated, and in order to save production cost, the high-temperature waste liquid is often cooled and recycled in production.

For practical production, a condenser for cooling the high-temperature waste liquid is sometimes installed on the roof of a workshop, and the water level of the high-temperature waste liquid discharged is mostly low, so that a water pump is required to pump the low-water-level high-temperature waste liquid into the condenser at high position for cooling treatment.

However, some workshops are too high, and a common water pump cannot provide enough lift to convey high-temperature waste liquid to a condenser on the roof of the workshop, so that the setting and use cost of a cooling system can be greatly increased if the high-power water pump is started.

To solve the above problems, a centrifugal pump is installed on the roof of the workshop in the prior art to increase the pump lift, which can smoothly convey the liquid to the condenser on the roof of the workshop for cooling, but does not reduce the setting and use of the cooling system; still other pumps use siphoning devices to replace centrifugal pumps to increase the lift of the pump at the floor of the plant, but the diameter of the siphon is generally constant when the siphoning device is set, which results in a constant liquid delivery rate of the siphoning device, which cannot follow the fit if the pump at the floor of the plant is to be changed.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, a liquid high-level conveying and cooling system comprises a water pump assembly 1 and a siphon assembly 2, wherein the water pump assembly 1 is installed on the horizontal ground and is used for pumping high-temperature liquid to the highest position reached by a lift, a pipeline of the siphon assembly 2 passes through a condenser 3 installed on the roof of a workshop, and the siphon assembly 2 can convey the liquid pumped by the water pump assembly 1 to the condenser 3 for cooling.

The water pump assembly 1 comprises a liquid inlet pipe 11, a pump 12 and a water reservoir 13, wherein the water reservoir 13 is arranged at the maximum lift of the pump 12. The high-temperature liquid enters the pump 12 from the liquid inlet pipe 11, and is pumped by the pump 12 to the reservoir 13 for storage.

The siphon assembly 2 comprises a plurality of siphon pipes 21 and a diversion chamber 22, the siphon pipes 21 are in an inverted U shape, two ends of each siphon pipe 21 are respectively communicated with the corresponding reservoir 13 and the corresponding diversion chamber 22, each siphon pipe 21 penetrates through the corresponding condenser 3 on the roof of the workshop, and liquid sucked by the corresponding siphon pipe 21 from the corresponding reservoir 13 is cooled by the corresponding condenser 3 when passing through the corresponding condenser 3. The reservoir 13 and the diversion chamber 22 are all communicated with the outside atmosphere, the height of the diversion chamber 22 is lower than that of the reservoir 13, a siphon effect is generated when the reservoir 13, the siphon pipe 21 and the diversion chamber 22 are filled with liquid, and the liquid in the reservoir 13 is continuously conveyed into the diversion chamber 22 through the siphon pipe 21.

The inner space of the diversion chamber 22 is divided into a liquid collecting cavity 2201 and a liquid discharging cavity 2202, the end head of the siphon pipe 21 is inserted into the liquid collecting cavity 2201, the liquid cooled by the condenser 3 fills the liquid collecting cavity 2201 first, the liquid overflows into the liquid discharging cavity 2202 after the liquid collecting cavity 2201 is filled, and the liquid discharging cavity 2202 is communicated with a related recycling pipeline, so that the cooled liquid is recycled.

Each siphon pipe 21 inserts the lower extreme opening part of cistern 13 and installs from closing component 4, from closing component 4 includes buoyancy circle 41, isolation leak circle 42, link 43 and sealing plug 44, isolation leak circle 42 fixed mounting is inside the siphon pipe 21 opening, and isolation leak circle 42 upper end is connected with siphon pipe 21 inner wall closure, and isolation leak circle 42 lower extreme is open, liquid in the cistern 13 enters into siphon pipe 21 through isolation leak circle 42. The sealing plug 44 is arranged in the isolation leakage ring 42, the lower end of the isolation leakage ring 42 can be sealed by moving the sealing plug 44 downwards, and the isolation leakage ring 42 can be opened by moving the sealing plug 44 upwards. The isolation leakage ring 42 and the inner wall of the siphon tube 21 form a cavity with an opening at the lower part, the buoyancy ring 41 is arranged in the cavity, the buoyancy ring 41 is connected with the sealing plug 44 through the connecting frame 43, and the connecting frame 43 erects the buoyancy ring 41 above the sealing plug 44.

The sealing plug 44 moves downwards under the gravity of the sealing plug and the pressure of the liquid in the siphon tube 21 to block the isolation leakage ring 42, at this time, the liquid in the siphon tube 21 cannot flow out from the isolation leakage ring 42, the pump 12 continuously pumps the liquid into the reservoir 13, the liquid level in the reservoir 13 gradually rises to the height of the buoyancy ring 41 until the liquid level in the reservoir 13 is at the lowest position, the buoyancy ring 41 can float upwards due to the continuous rising of the liquid level in the reservoir 13, so that the sealing plug 44 is lifted upwards to open the lower end of the siphon tube 21, and the liquid in the reservoir 13 enters the siphon tube 21.

If the siphon tube 21 with a deeper insertion depth is smaller than the pump fluid flow of the pump 12, the water level in the reservoir 13 will continue to rise until the siphon tube 21 with a shallower insertion depth into the reservoir 13 starts to drain, and when the drain fluid flow of the siphon tube 21 is balanced with the pump fluid flow of the pump 12, the water level in the reservoir 13 will not change. A plurality of siphon pipes 21 inserted into the reservoir 13 at different depths can provide a matched drain flow rate in time according to the pump flow rate of the pump 12.

After the pump 12 stops pumping water, the siphon tube 21 still pumps water, the water level of the reservoir 13 will gradually drop, and the buoyancy ring 41 will gradually move down until the sealing plug 44 drops to a position where the isolation leakage ring 42 is sealed. At this time, one end of the siphon tube 21 is blocked by the sealing plug 44, the other end of the siphon tube is sealed by the liquid in the liquid collecting cavity 2201, the siphon tube 21 is still filled with the liquid and is in a hollow state, and when the pump 12 is restarted, the siphon tube 21 can immediately generate a siphon action to start to suck liquid. Because the buoyancy ring 41 is positioned above the sealing plug 44, before the reservoir 13 is lowered to the lower end of the siphon tube 21, the buoyancy ring 41 drives the sealing plug 44 to descend so as to seal the siphon tube 21, and the liquid in the siphon tube 21 cannot leak, so that the vacuum can be always maintained, and the siphon action is generated immediately after the liquid level of the reservoir 13 rises.
