Description of the invention (0% * Field of the invention The present invention relates to a blower for purifying tanks, and more particularly to a blower for purifying tanks with a timing device for receiving time information provided by radio waves. Purification tanks for sewage purification are gradually spreading. This purification tank is, for example, a sedimentation separation tank for supplying sewage, and a sewage-supply contacting exhaust gas tank after the sedimentation separation tank removes solids and the like, and After contacting the exhaust tank, the sewage sludge is cleaned by microorganisms, used by i ~~ r7, and t ~ rm by 5 ~ / r. Disinfection? And it is discharged from the I outlet. There is a contact filter material in the contact exhaust groove. The surface of the contact filter material. The aerobic microorganisms y are propagated by the exhaust air sent from the blower through the pipeline and the air diffuser to decompose the organic matter in the sewage. The contact filter material is contaminated with this decomposition, so in order to make this pollution be For example, in a day, the cleaning is performed with: pre: λΕ, short time (hereinafter referred to as backwashing time), such as C at night; minutes, from the blower! To the contact filter to supply cleaning air. Conventionally, in order to supply exhaust air or backwash air <1 / ii blower is supplied to the exhaust tank J, the compressed air discharged from the blower is passed through a pipe connected in advance to a switching valve y for exhaust and backwash In order to switch the switching valve, a timing device with a battery-powered quartz oscillator is used in the clear time. The timing device judges that the backwash time reaches 3-5 hours. The switching valve will perform Change 527,473 V. invention is described in (2) 'that starts a backwashing, backwashing action after a predetermined time interval' when the predetermined time elapses, the switching valve can be switched, the end of the backwashing. [Problems to be Solved by the Invention] As mentioned above, the conventional blower for purifying tanks has a built-in battery-powered timing device, which has been shut down for a long period of time due to reasons such as being kept in stock or personnel. At that time, the timing device can continue to be operated by the battery. When the battery power is exhausted, the timing device will stop, and there is a problem that the current time or the backwash time must be reset. In addition, there must be a display element (such as a liquid crystal display, a light-emitting diode lamp, etc.) for displaying the time of the timing device, or a component required for setting the time, etc. The number of component points is high, and there is a problem of high cost. In addition, the temperature change in the blower for the purification tank causes an error in the output of the quartz oscillator, so there is a problem that the error must be corrected. Brief description of the invention The purpose of the present invention is to provide a blower for purifying tanks, which can solve the problems in the conventional technology. It has a timing device. It does not need to be equipped with a quartz oscillator, battery, display element, or time setting. Components, etc., and get the right time. [Means for solving the problem] In order to achieve the object, the blower for a purifying tank of the present invention performs backwashing and exhausting at a preset time, and is characterized by having a radio wave clock information receiving device for receiving radio time signals. Clock signal -4- 527473 V. Description of the invention (3) The time information provided by the receiving device is used for backwashing and exhausting. According to this feature, the quartz oscillator, battery, etc. required by the conventional technology become unnecessary, the number of component points is reduced, and an inexpensive structure can be formed. Even when the temperature in the blower for the purification tank changes, the radio wave The clock message receiving device can also receive the correct time, so it can provide the correct time information. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION Other objects of the present invention will be apparent from the following drawings and description. β FIG. 1 is a front internal structure view of a case of a blower for a purification tank to which the present invention is cut. The central part of the blower for the purification tank is provided with two compressors 1,2, and an air tank 3 is arranged below the blower for storing the compressed air of the compressors 1,2. A switching valve 4 communicating with the air tank 3 is arranged near the front of the air tank 3. The switching valve 4 is connected to the pipes 6a and 7a, and the pipes 6a and 7a constitute a normal exhaust outlet and a backwash exhaust outlet, respectively. An air filter element 11 made of a sponge or the like is provided on the upper portion of the blower for the purification tank, and the air filter element 11 is prevented from being lifted from the casing of the blower for the purification tank by a cover 12 attached thereto. Break away. A control signal receiving port 14 is provided at the right end of the blower for the purification tank, and is used to set control data such as the backwash start time or the backwash interval time at the control part (CPU) 13. Next, an embodiment of the present invention will be described with reference to the block diagram of FIG. In the figure, 20 is the integrated circuit of the radio wave clock device receiver, which can be connected to 527473 V. Description of the invention (4) Receives the radio wave time device information provided by the Japan Post Office. The radio wave clock device receiver integrated circuit 20 can be used, for example, corresponding to the transmission frequency of time information (40.0 kHz in Japan, 77.5kHz in Germany, and 60.0kHz in the United Kingdom and the United States) manufactured by Dimike Semiconductor Corporation. Integrated circuit of radio wave clock receiver. The structure of the radio wave clock device receiver integrated circuit 20 is shown in the block diagram shown in FIG. This circuit is conventional, and its structure and operation are omitted here. From the radio wave clock receiver integrated circuit 20, time information is supplied to the control unit 1 at every predetermined time interval. The control unit 1 3 inputs the backwash start time and the inverse from the control signal receiving port 14 in advance. Because of the washing interval time, the control unit 13 can sense the time information supplied from the radio wave clock receiver integrated circuit 20, and when it judges that the start time of the reverse washing is reached, it will output the Η (high) level. The driving signal to the driving circuit of the switching valve 4. Therefore, the switching elements such as the thyristor 21 constituting the circuit are closed (ON) during the backwashing time. Secondly, after the backwash time has elapsed, when the backwash end time is reached, the control unit 13 outputs a driving signal at the L (low) level to the thyristor 21. When the control section 13 outputs a driving signal at the L (low) level, the thyristor 21 will be opened (OFF). As shown in FIG. 2, the commercial AC power source 22 is connected in series with the switching valve solenoid 4 a of the switching valve 4 during the period when the semiconductor thyristor 21 is closed (ON). That is, during the backwash time, the AC current i output from the AC power source 22 flows into the switching valve solenoid 4a. Therefore, the switching valve 4 is switched to make the pressure sent from the air tank 3 527473 V. Description of the invention (5) The compressed air is sent out through the pipe 7a, and the backwash exhaust is performed. When the time for exhaust gas to be backwashed has elapsed, the thyristor 21 is opened (OFF). Therefore, the alternating current I does not flow into the solenoid 4 a for the switching valve, and the t-blade valve 4 is rebounded by the spring 4 b to return to the original position. As a result, the compressed air sent from the air tank 3 passes through the tube 6 8 L? End the backwash exhaust and perform the normal exhaust again.) As described above, according to the embodiment of the present invention, the radio wave time information provided by the Japan Post General Administration can be received and used in the purification tank. Blowers ~ The quartz oscillator, the battery for power supply, or the display elements for displaying time information are not required inside the fan. Also, when the blower for the purification tank is installed in the place where the sun shines, it is especially likely in summer. The inside of the blower for the purification tank becomes high temperature, so that there may be an error in the output of the quartz oscillator. However, the reason that the quartz oscillator is not used in the present invention is completely a concern. [Effects of the Invention] The above description is obvious. According to the present invention, since one radio wave hour capable of receiving radio time information is used: a clock receiving means, it is not necessary to use a quartz oscillator used in a conventional device. . Therefore, even if the temperature in the blower for the purification tank is greatly changed, the correct time information can be provided to the blower for the purification tank. And the battery in the conventional device used to supply electric power to the quartz oscillator, or the liquid crystal screen or light-emitting diode lamp to confirm the components used in time is not necessary, so that these components can be reduced. Therefore, the device 527473 can be made cheap. Furthermore, adjustments to the current time or timer are not necessary, and they do not require maintenance.
