The vacuum kneader comprises a vacuum pump and a closed reaction kettle, and the inner cavity of the reaction kettle is a kneading chamber of the kneader and is used for kneading materials. Because the vacuum kneader can produce steam in the process of kneading materials, and the vacuum pump is just to discharge the steam in the kneading chamber, because the temperature of steam is higher, because the inner chamber in the vacuum pump needs to be cooled down, avoid wearing and tearing the part in the vacuum pump and damaging the vacuum pump.
At present, as shown in fig. 1, the cooling system for the existing vacuum kneader comprises a cooling tower 10 and a cooling water inlet pipeline 30, wherein a vacuum pump 402 of the vacuum kneader is provided with a steam inlet, a water outlet and a cooling water inlet which are communicated with the inner cavity of the vacuum kneader, the steam inlet is communicated with a kneading chamber 401 through a steam inlet pipe 50, the water outlet is communicated with a water outlet pipe 52, and the opposite ends of the cooling water inlet pipe are respectively communicated with the cooling water inlet of the vacuum pump 402 and a water storage tank 101 of the cooling tower 10; under the negative pressure of the vacuum pump 402, steam in the kneading chamber 401 enters the inner cavity of the vacuum pump 402; the steam entering the vacuum pump 402 exchanges heat with the cooling water entering the vacuum pump 402, and the hot water after heat exchange is pumped into the cooling tower 10 by the power pump 520 arranged on the drain pipe 52 to be cooled and then enters the inner cavity of the vacuum pump 402, so that the circulation is realized, and the purpose of cooling the vacuum pump 402 is achieved.
However, since the heat exchange between the steam entering the vacuum pump 401 and the cooling water entering the vacuum pump 40 may cause the heat exchanged hot water to contain gas, the power pump 520 may be damaged due to the defect of idle running of the power pump 520 during the process of pumping the heat exchanged hot water into the cooling tower 10 by the power pump 520; in addition, since the volume of the water storage tank 101 of the cooling tower 10 is small, when the plurality of vacuum kneaders 40 are simultaneously operated, that is, when the vacuum pumps 402 of the plurality of vacuum kneaders 40 are all communicated with the water storage tank 101 of the cooling tower 10 through the water inlet pipe, the supply amount of the cooling water after the cooling tower 10 is cooled is insufficient; when only one vacuum kneader 40 is operated, that is, only one vacuum pump 402 of the vacuum kneader 40 is communicated with the water storage tank 101 of the cooling tower 10 through the water inlet and cooling pipe, in order to meet the supply amount of water in the water storage tank 101 of the cooling tower 10, the flow rate of the water cooled by the cooling tower 10 into the water storage tank 101 is generally larger than the flow rate of the water entering the vacuum pump 402 of the vacuum kneader 40 from the water storage tank 101, so that the water in the water storage tank 101 of the cooling tower 10 overflows fully when the vacuum kneader 40 is operated for a period of time, and water resources are wasted.

The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.
Referring to fig. 2, a preferred embodiment of the present utility model shows a cooling system for a vacuum kneader, comprising a cooling tower 10, a cooling water tank 20 and a cooling water inlet pipe 30; wherein, the cooling tower 10 is provided with a water storage tank 101 for storing the cooled cooling water; the cooling water tank 20 is arranged at the bottom of the water storage tank 101 and is communicated with the water storage tank 101; one end of the cooling water inlet pipeline 30 is communicated with the cooling water tank 20 in a sealing way, and the other end of the cooling water pipeline is at least communicated with a cooling water inlet of the vacuum pump 402 of the vacuum kneader 40 in a sealing way, so that water cooled by the cooling tower 10 can enter the water storage tank 101, the cooling water tank 20 and the cooling water inlet pipeline 30 in sequence, and finally enter the cooling water inlet of the vacuum pump 402 of the vacuum kneader 40 to cool the vacuum pump 402. That is, it can be understood that when the cooling system for the vacuum kneader 40 of the present utility model is used, when the water inlets of the vacuum pumps 402 of the plurality of vacuum kneaders 40 are all communicated with the water storage tank 101 of the cooling tower 10 by the cooling pipeline, the cooling water cooled by the cooling tower 10 enters the water storage tank 101 of the cooling tower, and the volume of the water storage tank 101 is increased by the cooling water tank 20, so that the water in the water storage tank 101 of the cooling tower 10 is not insufficient for supplying the vacuum pumps 402 of the plurality of vacuum kneaders 40; when only the water inlet and the cooling water outlet of the vacuum pump 402 of the vacuum kneader 40 are communicated with the water storage tank 101 of the cooling tower 10 through the cooling pipeline, the volume of the water storage tank 101 of the cooling tower 10 is increased through the cooling water tank 20, so that the overflow of the water in the water storage tank 101 of the cooling tower 10 can be effectively avoided, and water resources are saved.
Of course, the vacuum pump 402 of the vacuum kneader 40 is also provided with a steam inlet and a water outlet which are communicated with the inner cavity of the vacuum pump 402, and the steam inlet and the water outlet are communicated with the cooling water inlet through the inner cavity of the vacuum pump 402. When the vacuum pump 402 of the vacuum kneader 40 is connected with the kneading chamber 401 of the vacuum kneader 40, the steam inlet is communicated with the kneading chamber 401 of the vacuum kneader 40 through the steam inlet pipe 50, the water outlet is communicated with the spraying system 102 of the cooling tower 10 through the water outlet pipe 52, so that steam generated in the kneading chamber 401 of the vacuum kneader 40 during kneading materials can enter the inner cavity of the vacuum pump 402 through the steam inlet pipe 50 under the negative pressure of the vacuum pump 402 to be mixed and heat exchanged with cooling water entering the vacuum pump 402 from the cooling water inlet, and the heat exchanged hot water is discharged into the cooling tower 10 through the water outlet pipe 52. Since the cooling tower 10 is generally installed on the roof, it is necessary to provide a power pump 520 on the drain pipe 52, and the hot water discharged from the water outlet is fed into the cooling tower 10 to be cooled by the power pump 520, and the cooled water of the cooling tower 10 is sequentially introduced into the water storage tank 101 and the cooling water tank 20 of the cooling tower, and finally introduced into the vacuum pump 402 of the vacuum kneader 40 through the cooling water inlet pipe 30, thereby circulating.
The cooling tower 10 is provided with a cooler coil 103, one end of the cooler coil 103 is used for feeding cooling water, the other end is used for discharging hot water, and the water fed into the spraying system 102 of the cooling tower 10 from the water discharge pipe 52 is sprayed into the cooling pipeline downwards through each spray header, so that the sprayed hot water exchanges heat with cold water in the cooling pipeline to achieve a cooling effect, and the cooled water flows into the water storage tank 101 of the cooling tower 10 from top to bottom.
Since the heat exchange between the steam entering the vacuum pump 402 and the cooling water entering the vacuum pump 402 may result in the heat exchanged hot water containing gas, the power pump 520 may be damaged due to the idle running defect of the power pump 520 during the process of pumping the heat exchanged hot water into the cooling tower 10 by the power pump 520. In order to solve the above-mentioned drawbacks, the present inventors have added a water tank 60 to allow the water outlet of the vacuum pump 402 to communicate with the water discharge pipe 52 through the water tank 60, that is, the water outlet of the vacuum pump 402 communicates with the water tank 60 through the water discharge pipe 51, and the water tank 60 communicates with the cooling tower 10 through the water discharge pipe 52. Of course, the top end of the water tank 60 is of an open structure, so that the water discharged from the water outlet of the vacuum pump 402 is discharged from the water tank 60, and then the water in the water tank 60 is pumped into the cooling tower 10 for cooling by the power pump 520 arranged on the water drain pipe 52, thereby effectively avoiding the power pump 520 from idling and wearing the power pump 520.
It should be noted that the process of kneading materials by the vacuum kneader 40 belongs to the prior art, and is not described here.
In the present embodiment, the cooling water inlet pipeline 30 is communicated with the cooling water inlet through the water tank 60, that is, one end of the cooling water inlet pipeline 30 is communicated with the cooling water tank 20, the other end is communicated with the water tank 60, and the water tank 60 is communicated with the cooling water inlet of the vacuum pump 402 in a sealing way through the water inlet pipe 31, so that the water level in the cooling water tank 20 is prevented from being too high or too low by controlling the liquid level in the water tank 60, the power pump 520 and the opening of the valves on the cooling water inlet pipeline.
In this embodiment, the present utility model further includes a control system for controlling the valve on the coolant inlet pipe 30 and the power pump 520; the low-level water gauge 70 is arranged in the water tank 60, when the low-level water gauge detects that the water level in the water tank 60 is in a low water level line, the control system controls the valve on the cooling water inlet pipeline 30 to be opened, so that the cooling water in the cooling water tank 20 enters the water tank 60 and simultaneously controls the power pump 520 to stop running, thereby effectively avoiding insufficient water supply of the vacuum pump 402 by the water tank 60 and overflow of water in the cooling water tank 20 due to overhigh water level in the cooling water tank 20 caused by overlow water level in the water tank 60; in addition, a middle water level gauge 71 is further arranged in the water tank 60, when the middle water level gauge 71 detects that the water level in the water tank 60 is in a middle water level line, the control system controls a valve on the cooling water inlet pipeline 30 to be opened, and simultaneously controls the power pump 520 to operate and extract water in the water tank 60 to enter the cooling tower 10 for cooling, so that the whole cooling system is in a circulating working state; of course, the water tank 60 is also provided with a high-level water gauge 72, when the high-level water gauge 72 detects that the water level in the water tank 60 is in a high water level line, the control system controls the valve on the cooling water inlet pipeline 30 to be closed, and simultaneously controls the power pump 520 to operate and pump water in the water tank 60 into the cooling tower 10 for cooling, so that the water supply is not enough due to the fact that the water level in the water tank 60 overflows too high and the water level in the cooling water tank 20 is too low.
In this embodiment, the water tank 60 is further provided with an automatic water replenishing system, which is composed of a water pump and a water pipe, and of course, the water pump is also controlled and controlled by the control system, and the automatic water replenishing system is used for automatically replenishing water into the water tank 60. That is, it can be understood that when the water level in the water tank 60 is at the low water level, since the water in the water tank 60 is always supplied to the vacuum pump 402, the automatic water replenishing system automatically replenishes the cooling water in the water tank 60 if the cooling water entering the water tank 60 from the cooling water tank 20 is insufficient to reach the low water level.
In this embodiment, the cooling water in the cooling water tank 20 enters the water tank 60 by a self-flowing manner, so that one power pump 520 can be saved, and electricity can be saved to a certain extent.
The above embodiments are only preferred embodiments of the present utility model, and the scope of the present utility model is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present utility model are intended to be within the scope of the present utility model as claimed.
