Anti-blocking water outlet of temporary culture tank

The utility model discloses an anti-blocking water outlet of a temporary culture tank, which belongs to the technical field of water outlets and comprises a sieve pore ball, a conical pipe and a water outlet pipe. The anti-blocking device is composed of a sieve mesh ball and a conical pipe, the conical pipe is arranged below the sieve mesh ball, a thread vortex flow guide groove is formed in the conical pipe, and water flowing into the sieve mesh ball is guided to rapidly flow into the water outlet pipe in a vortex mode. The whole anti-blocking device is placed above the water outlet pipe, and water flow in the temporary culture tank enters the conical pipe through sieve pores in the surface of the sieve pore ball and rapidly flows into the water outlet pipe in a vortex mode through drainage of the threaded vortex flow guide groove. The outlet pipe anti-blocking device is low in manufacturing cost and suitable for anti-blocking of outlet pipes with different hole diameters; the sieve hole balls are large in w
