Description
技术领域technical field
本发明属于污水源热泵水处理设备领域，具体涉及一种旋流式污水过滤装置。The invention belongs to the field of sewage source heat pump water treatment equipment, and in particular relates to a swirl type sewage filtering device.
背景技术Background technique
根据污水处理情况的不同，污水水源热泵可以分为以未处理的污水即原生污水作为热源和以处理后的污水作为热源的污水水源热泵[1]。以处理后的污水即二级出水或中水作热泵热源，水质较好，处理过程比较简单，系统仅需要一级过滤器即可[2]。但是，由于污水处理厂一般位于市区边缘，距热用户距离较远，若热泵站设在污水处理厂内，则供热管线较长，热损失较大，而且也增加了热泵系统中水处理的投资费用[3]。According to different sewage treatment conditions, sewage water source heat pumps can be divided into sewage water source heat pumps that use untreated sewage, that is, raw sewage as a heat source, and sewage water source heat pumps that use treated sewage as a heat source [1] . The treated sewage, that is, the secondary effluent or reclaimed water, is used as the heat source of the heat pump. The water quality is good and the treatment process is relatively simple. The system only needs a primary filter [2] . However, since sewage treatment plants are generally located at the edge of urban areas and are far away from heat users, if the heat pump station is located in the sewage treatment plant, the heating pipeline will be longer, the heat loss will be greater, and the water treatment in the heat pump system will also be increased. The investment cost [3] .
使用一级过滤器发现，过滤器工作时由于一些粘性大的污泥粘附在过滤器内壁上，长期造成过滤器堵塞，处理能力下降。另外，污泥处理时，还易造成工作环境的污染。Using the primary filter, it is found that when the filter is working, some sticky sludge adheres to the inner wall of the filter, causing the filter to be clogged for a long time and the processing capacity to decline. In addition, when sludge is disposed of, it is also easy to cause pollution to the working environment.
发明内容Contents of the invention

所述旋转格栅的个数为6-12个。The number of the rotating grids is 6-12.
所述遮蔽罩左右对称设置有两个。There are two shielding covers symmetrically arranged left and right.
本发明旋转格栅动作原理：当旋转格栅内污物积累，引起进出口腔内产生一定的压差，当压差达到上限值时，压力传感器检测后，由PLC控制器启动电机，电机带动格栅旋转90°，然后稍做停留0-30秒，此时间可以调整，继续旋转90°后停止，完成一个周期的运转。当旋转格栅完成第一个90°时，限位开关发出信号，启动排污口电磁阀动作，打开排污；当延时时间到后，排污电磁阀关闭。同理，继续上述动作步骤。The action principle of the rotary grid of the present invention: when the dirt in the rotary grid accumulates, a certain pressure difference is generated in the inlet and outlet chambers. When the pressure difference reaches the upper limit, after the pressure sensor detects, the PLC controller starts the motor, and the motor drives The grid rotates 90°, and then stays for 0-30 seconds, this time can be adjusted, and stops after continuing to rotate 90°, completing a cycle of operation. When the rotating grill completes the first 90°, the limit switch sends out a signal, starts the action of the solenoid valve at the sewage outlet, and opens the sewage discharge; when the delay time is up, the sewage solenoid valve closes. Similarly, continue the above action steps.
