Abstract

PURPOSE:To enable the air pollution to be prevented when harmful gas is used, by allowing low temperature compressed gas to flow into a casing and cool it in no relation to the outside air from a branch pipe branching from cooling pipes, provided in the periphery of a motor and exposed in cooling air of said motor. CONSTITUTION:A blower provides in the periphery of a motor 21 cooling pipes 31, exposed in cooling air of said motor 21, while a guide wall 32 which enables the cooling air not only to give a cooling effect to the cooling pipes 31 but also to cool the whole unit of blowers 1, 11. And the Root's blower both connects said cooling pipe 31 with a delivery pipe 7 of the blowers 1, 11 and forms the cooling pipe so that its branch pipe 37 can allow a part of compressed gas cooled to a low temperature to flow into a flow inlet (not shown in the drawing) of a casing 2. In this way, the air pollution can be prevented when harmful gas is used because the blower, being different from that compression heat is decreased by allowing the outside air to flow into the flow inlet in a delivery side of the casing 2 as in the past, allows the compressed gas, after it is cooled, to flow into the casing in no relation at all to the outside air.

(Prior Art) As shown in Fig. 5, the Roots blower has a Roots rotor dld that rotates in the opposite direction as shown by the arrow in a casing a that has a suction port, a discharge port, and a C. Then, communication with the suction port C is cut off by one leaf d', and the casing a, the leaf d', and the other leaf d''
When the leaflet d" crosses the discharge port C, the high pressure of the discharge port C, which has higher pressure and temperature, is trapped between the Normally, gas is introduced to cause compression, but this compression action causes the temperature of both the discharged gas and the casing a to rise, so the pressure of the trapped gas e is higher than that of the gas, and moreover, Providing inlets f and f for feeding gas at a temperature lower than the temperature of gas C on the discharge side of the casing a is advantageous for the roots blower 1 for vacuum or the program for compression.

When the gas is introduced from the inlets f and f on the discharge side of the pump, when the structure is such that normal temperature air or air cooled by an intercooler is sent in, when used for sucking or compressing harmful gases, it is necessary to avoid air pollution. Improvements are desired because it is dangerous.

On the other hand, the gas that is sucked from the suction pipe (6) of the first stage blower (1), sucked by the Roots-type rotors (3), (3), compressed, and discharged to the discharge pipe (7) is heated by compression heat. (normally about 230°C, in the case of the present invention, the inlet (
9), the compressed gas reaches a temperature of approximately 120° C. and is sent to the cooling pipe (31) through the compressed gas feed pipe (35). The limb pipe (31) is exposed to the cooling air of the cooling fan (23), and is cooled (its temperature is lower than (The temperature is about 30°C.) The cooling gas is sent alternately from the inlets (9), (9) provided in the casing (2) of the first stage blower (1) through the branch pipe (37). , before being compressed by the gas in the discharge pipe (7), compression is caused by the gas in the branch pipe (37) at a much lower temperature;

Table 1 (Effects of the Invention) The present invention provides a cooling pipe on the outer periphery of the motor that receives cooling air from the motor, and a guide wall that allows the cooling effect of the cooling air to cool not only the cooling pipe but the entire blower. The cooling pipe is connected to the discharge pipe of the blower, and a part of the cooled compressed gas flows into the inlet of the casing from a branch pipe branched from the cooling pipe, as in the United States. The blower does not attempt to reduce the heat of compression by letting outside air flow into the inlet on the discharge side of the casing, but instead cools the compressed gas and lets it flow in, completely unrelated to the outside air. It is also possible to use
