Description

Technical Field

[0001] The utility model belongs to the technical field of condensate pumps, and particularly relates to an automatic water replenishment system for a KLD wire drying drum condensate pump. Background Art

[0002] KLD drying drum is a key equipment in tobacco processing. Its main function is to dry the tobacco. By heating and blowing, the water in the tobacco evaporates quickly, so as to adjust the moisture content of the tobacco. KLD drying drum plays a vital role in the tobacco processing process, which directly affects the quality of the tobacco and the quality of the finished tobacco.

[0003] The main function of the condensate pump in the KLD wire drying drum is to remove the condensate generated during the wire drying process. In actual production, the condensate pump of the KLD wire drying drum may run idle. The condensate pump running idle will cause: 1. Equipment damage. When the condensate pump runs idle, there is no water to lubricate and cool the bearings and seals of the pump, which may cause bearing wear and seal aging, thereby shortening the service life of the pump; 2. Energy waste. The idling condensate pump still consumes electricity, but has no actual working effect, resulting in energy waste; 3. Reduced drying effect. If the condensate pump cannot discharge the condensate in time, the humidity in the wire drying drum will increase, affecting the drying effect of the tobacco and causing uneven moisture content of the tobacco; 4. Safety hazards. Long-term idling may cause the pump to overheat, and even cause safety problems such as fire. Utility Model Content

[0026] Furthermore, the condensate pump body 1 is provided with an automatic water replenishment system 5, and the automatic water replenishment system 5 includes a condensate replenishment hole 51, an automatic water replenishment pipeline 52, an automatic water replenishment valve 53, a low water level sensor 54, a high water level sensor 55 and a control unit. The condensate replenishment hole 51 is provided on the condensate pump body 1 and is close to the end of the condensate pump inlet pipeline 3, the condensate replenishment hole 51 is communicated with the condensate pump body 1, the automatic water replenishment pipeline 52 is installed at the condensate replenishment hole 51, the automatic water replenishment pipeline 52 is communicated with the condensate pump body 1, and the automatic water replenishment pipeline 52 is provided with the low water level sensor 54, the high water level sensor 55 and the automatic water replenishment valve 53 from bottom to top in sequence;

[0027] Specifically, the automatic water replenishment pipeline 52 is in an L-shaped structure, a section of the automatic water replenishment pipeline 52 connected to the condensate replenishment hole 51 is parallel to the horizontal plane, and the other section is arranged perpendicular to the horizontal plane. The automatic water replenishment pipeline 52 and the condensate pump body 1 form a communicating vessel structure. The internal situation of the condensate pump body 1 can be understood in real time through the automatic water replenishment pipeline 52, so the automatic water replenishment pipeline 52 can use a transparent pipeline.

[0028] The low water level sensor 54 is installed horizontally at a height higher than the condensed water replenishment hole 51 .

[0029] The low water level sensor, the high water level sensor 55, the automatic water replenishment valve and the control unit are electrically connected.

[0030] In the present invention, a condensate pump exhaust hole 11 is provided on the condensate pump body 1, and the condensate pump exhaust hole 11 is arranged close to the end of the condensate pump motor 2. The condensate pump exhaust hole 11 is connected to the condensate pump body 1, and a condensate pump exhaust pipeline 6 is provided on the condensate pump exhaust hole 11. A condensate pump exhaust valve 7 is provided on the condensate pump exhaust pipeline 6, and the condensate pump exhaust valve 7 is electrically connected to the control unit.

[0032] The specific working principle of a KLD wire drying drum condensate automatic water replenishment system:

[0033] The water level inside the condensate pump body 1 is detected in real time by using the high and low water level sensors of the condensate pump. When the water level inside the condensate pump body 1 is lower than the position of the low water level sensor, the control unit controls to open the automatic water replenishment valve 53 and the condensate pump exhaust valve 7 at the same time, so that the condensate pump body 1 is automatically replenished with water (tap water enters the condensate pump body 1 through the automatic water replenishment pipeline 52);

[0034] When the water level inside the condensate pump body 1 is higher than the position of the high water level sensor, the control unit controls the automatic water replenishment valve 53 and the condensate pump exhaust valve 7 to close simultaneously, and stops water replenishment.

[0035] The above operation can ensure that the condensate pump body 1 can be automatically replenished with water when the condensate pump body 1 is running idle due to lack of water, thereby avoiding the condensate pump body 1 from running idle.

[0036] In summary, the utility model provides an automatic water replenishing system for the condensate water pump of the KLD wire drying drum. The automatic water replenishing system determines whether the condensate water pump body needs to be replenished with water by detecting the water level in the condensate water pump body, thereby preventing the condensate water pump body from idling and causing damage to the pump body. At the same time, it also avoids the condensate water in the condensate water pipeline of the KLD wire drying drum from being unable to be discharged in time due to idling of the condensate water pump body due to lack of water, resulting in accumulation of condensate in the condensate water pipeline, and steam being unable to normally enter the KLD wire drying drum thin plate for heat exchange, resulting in abnormal temperature of the KLD wire drying machine barrel and cracking of the thin plate.
