Description

Technical Field

[0001] The invention relates to the technical field of diaphragm pumps, and in particular to a pneumatic diaphragm pump with a temperature control function. Background Art

[0002] Pneumatic diaphragm pump is a new type of liquid material conveying equipment, which can replace the use of submersible pumps, sewage pumps, centrifugal pumps and other equipment. The pump has the characteristics of small size, light weight, convenient installation and flexible use. Because it can convey liquids containing solid particles and has no explosion-proof problems, it is widely used in more and more industries such as petrochemicals, coatings, ships, water treatment, food, papermaking, mining, etc.

[0003] Due to the conveying characteristics of the diaphragm pump, its diaphragm is a vulnerable part. This is because when the linkage rod of the air motor drive part carries the diaphragm to reciprocate for a long time with high frequency, the reciprocating bending part of the pad and the diaphragm is prone to thermal fatigue. The reciprocating bending part of the diaphragm is in a thermal fatigue working state for a long time, which will aggravate the loss of the diaphragm. Once the diaphragm is broken, the diaphragm pump will not be able to work normally, affecting the material conveying work, etc.; the existing solution is that the operator regularly inspects, maintains and replaces the diaphragm of the diaphragm pump, and replaces it before the diaphragm reaches the fatigue life to avoid machine failure. However, this frequent replacement of the diaphragm not only takes up the working time of the operator, but also puts the diaphragm pump in a shutdown state, affecting the material transmission efficiency, and the material cost of the diaphragm is not well controlled;

[0004] Therefore, we provide a pneumatic diaphragm pump with temperature control function. Without affecting the original pneumatic operation, the guide component and the transmission component are used to control the temperature of the diaphragm well, so that it can work in a good working temperature environment and reduce the situation of the diaphragm overheating fatigue operation loss. Summary of the invention

[0011] When the connecting heads at both ends of the linkage rod in the transmission assembly make reciprocating motion in the first diaphragm chamber and the second diaphragm chamber, the second diaphragms in the first diaphragm chamber and the second diaphragm chamber contact the annular sleeve at intervals, so that the two second diaphragms move toward the adjacent first diaphragms at intervals and compress the spring, so that the two second diaphragms squeeze the liquid in the two liquid storage tanks at intervals respectively, so that the liquid in the two liquid storage tanks can flow with each other after being heated or cooled by the functional cabin.

[0012] When the first diaphragm and the second diaphragm need to be cooled, the controller controls the current flow direction of the P-type semiconductor and the N-type semiconductor in the functional box according to the Peltier effect principle, so that the metal conductor end connected to the functional sheet is the cooling end, so that the functional sheet cools the coolant in the functional cabin, so that the liquid squeezed back and forth by the two liquid storage tanks is also cooled after passing through the functional cabin, so that the coolant in the two liquid storage tanks cools the first diaphragm and the second diaphragm, reduces the overheating and wear of the diaphragm caused by the high-frequency reciprocating motion, and helps to extend the service life of the diaphragm;

[0023] 1. By setting the transmission component in coordination with the guide component, when the connecting heads at both ends of the linkage rod make reciprocating motion in the first diaphragm chamber and the second diaphragm chamber, the second diaphragms in the first diaphragm chamber and the second diaphragm chamber are spaced against the annular sleeve, so that the two second diaphragms move toward the adjacent first diaphragms at intervals and compress the spring, so that the two second diaphragms squeeze the liquid in the two liquid storage tanks respectively at intervals, so that the liquid in the two liquid storage tanks can circulate with each other after being heated or cooled by the functional cabin, so as to utilize the linkage rod that is originally moving to cooperate with the second diaphragm to squeeze the liquid storage tank, so that the coolant in the liquid storage tank can be well circulated after being cooled or heated by the functional cabin, thereby effectively cooling or heat-insulating the diaphragm, so that the diaphragm works and operates in a good temperature control environment, ensuring that the diaphragm operates in a good working condition, improving the working stability of the diaphragm, and providing a strong guarantee for the service life of the diaphragm.

[0024] 2. When the diaphragm pump of the present invention needs to cool the first diaphragm and the second diaphragm, based on the Peltier effect principle, the controller controls the current flow direction of the P-type semiconductor and the N-type semiconductor in the functional box, so that the metal conductor end connected to the functional sheet is the cooling end, and the functional sheet cools the coolant in the functional cabin, so that the liquid squeezed back and forth by the two liquid storage tanks is also cooled after passing through the functional cabin, so that the coolant in the two liquid storage tanks cools the first diaphragm and the second diaphragm, reduces the overheating and wear of the diaphragm caused by high-frequency reciprocating motion, and helps to extend the service life of the diaphragm.

[0025] 3. When the diaphragm pump of the present invention needs to keep the first diaphragm and the second diaphragm warm, the controller changes the current flow direction of the P-type semiconductor and the N-type semiconductor in the functional box according to the Peltier effect principle, so that the metal conductor end connected to the functional sheet is the heat release end, so that the functional sheet heats the coolant in the functional cabin, and the liquid squeezed back and forth by the two liquid storage tanks is also cooled after passing through the functional cabin, so that the coolant in the two liquid storage tanks can keep the first diaphragm and the second diaphragm warm, preventing the diaphragm from being damaged by frostbite due to the diaphragm pump conveying low-temperature materials, which helps to extend the service life of the diaphragm.
