The vacuum equipment is used to form a certain vacuum negative pressure in the closed network. Then, through the control of the front-end collection well, the sewage enters the network. Then, under the action of the negative pressure suction force, the sewage is transported in the direction where the negative pressure is generated (negative pressure station).

[0003] However, when the existing negative pressure collection system collects sewage, the solid particles in the sewage are not effectively filtered, which may clog the pipes, affect the normal operation of the system, reduce the sewage collection efficiency, or accumulate in the negative pressure collection well, increase the cleaning frequency of the negative pressure collection well, increase the cleaning burden, and have low practicality.

DETAILED DESCRIPTION

[0016] Reference Figure 1 to Figure 2 The utility model is further described in detail.

[0017] A smart negative pressure collection system includes a negative pressure collection well 01, a negative pressure collection pipe 02 and a negative pressure station 03. The negative pressure collection well 01 and the negative pressure station 03 are connected through the negative pressure collection pipe 02. A filter device 04 is arranged at the front end of the negative pressure collection well 01. The filter device 04 includes a filter box 1 connected to the negative pressure collection well 01, a collection box 2 connected to the filter box 1, a filter screen 3 arranged in the filter box 1 and a cylinder 4 for vibrating the filter screen 3. The filter screen 3 is inclined toward the collection box 2, and one end of the filter screen 3 is hinged to the inner wall of the filter box 1. An elastic block 6 connected to the other end of the filter screen 3 is installed on the inner wall of the filter box 1. The other end of the filter screen 3 moves on the inner wall of the filter box 1 through the elastic block 6. The cylinder 4 is installed on the inner wall of the filter box 1, and the output end of the cylinder 4 corresponds to the other end of the filter screen 3. The output end of the cylinder 4 is installed with a vibration hammer 7 matched with the filter screen 3. The cylinder 4 drives the vibration hammer 7 to knock the filter screen 3 to vibrate the filter screen 3.

[0018] The negative pressure collection system also includes a controller. A water level detector 5 connected to the controller signal is installed in the filter box 1, and the cylinder 4 is connected to the controller signal.

[0019] Working principle: Before the sewage enters the negative pressure collection well 01, the sewage passes through the negative pressure collection pipe 02 and is filtered by the filter device 04, and then enters the negative pressure collection well 01 and the negative pressure station 03 in turn through the negative pressure collection pipe 02. When the sewage is filtered by the filter device 04, the sewage enters the filter box 1 of the filter device 04, and the large solid particles in the sewage are filtered through the filter screen 3 in the filter box 1 to prevent the large solid particles from clogging the negative pressure collection pipe 02 and affecting the normal operation of the system. The filtered sewage is discharged through the negative pressure collection pipe 02 and enters the negative pressure collection well 01 and the negative pressure station 03 in turn. Since the large solid particles continue to accumulate on the filter screen 3, it will reduce the sewage passing through the filter screen. 3, when the water level detector 5 detects that the water level is lower than the position of the water level detector 5, it sends a signal to the controller, and the cylinder 4 is controlled by the controller to work, and one end of the filter screen 3 is hinged on the inner wall of the filter box 1. The cylinder 4 drives the vibration hammer 7 to knock the other end of the filter screen 3, so that the elastic block 6 connected to the other end of the filter screen 3 is deformed and movable to make the filter screen 3 vibrate, and cooperate with the large solid particles to be inclined toward the collection box 2, so that the large solid particles accumulated on the filter screen 3 fall into the collection box 2 for collection, reducing the solid particles flowing into the negative pressure collection well 01, and reducing the cleaning frequency of the negative pressure collection well 01, which is highly practical;

[0020] At the same time, the cylinder 4 vibrates the filter screen 3 through the vibrating hammer 7 to facilitate the large solid particles accumulated on the filter screen 3 to fall into the collection box 2 for collection, which can avoid the accumulation of too many large solid particles on the filter screen 3, resulting in a reduction in the flow of sewage through the filter screen 3, thereby affecting the efficiency of sewage entering the negative pressure collection well 01 through the negative pressure collection pipe 02. By vibrating the filter screen 3, the clogged mesh of the filter screen 3 is cleared, and the mesh of the filter screen 3 is prevented from being clogged by small particles and affecting the circulation of sewage, further avoiding affecting the efficiency of sewage entering the negative pressure collection well 01, thereby improving the sewage collection efficiency and enhancing practicality.

[0021] The collecting box 2 includes a box cover 201. Opening the box cover 201 facilitates cleaning of the solid particles collected in the collecting box 2. The filter box 1 is connected to a slag guide pipe 8 connected to the collecting box 2. The slag guide pipe 8 corresponds to one end of the filter screen 3. The collecting box 2 and the filter box 1 are connected through the slag guide pipe 8, so that the solid particles filtered on the filter screen 3 enter the collecting box 2 through the slag guide pipe 8 for collection, and a solenoid valve 801 for controlling the opening and closing of the slag guide pipe 8 is installed on the slag guide pipe 8. The solenoid valve 801 is connected to the controller signal. When the filter screen 3 filters solid particles in sewage, the solenoid valve 801 is in a closed state to prevent sewage from directly entering the collecting box 2. When the water level detector 5 sends a signal to the controller, the controller controls the cylinder 4 to work and controls the solenoid valve 801 to open at the same time, so that the filter screen 3 vibrates so that the solid particles on it enter the collecting box 2 through the slag guide pipe 8 for collection.

[0022] The collecting box 2 is connected with a telescopic hose 9 connected with the slag guiding pipe 8, and handles 202 for easy lifting are installed on both sides of the collecting box 2. The telescopic hose 9 and the slag guiding pipe 8 are respectively provided with a first connecting hole 901 and a second connecting hole 802 corresponding to each other. The telescopic hose 9 is sleeved on the slag guiding pipe 8 and the first connecting hole 901 and the second connecting hole 802 are connected by bolts. The telescopic hose 9 and the slag guiding pipe 8 are detachably connected by bolting the first connecting hole 901 and the second connecting hole 802, so that the solid collected in the collecting box 2 can be easily removed when the box cover 201 is opened. When cleaning solid particles, the bolts are removed from the first connecting hole 901 and the second connecting hole and the telescopic hose 9 is shortened, so that the telescopic hose 9 is removed from the slag guiding pipe 8. At this time, the solenoid valve 801 is in a closed state, which facilitates the cleaning box and the opening of the box cover 201 to clean the solid particles collected in the collection box 2, thereby reducing the cleaning difficulty. The setting of the handle 202 facilitates the application of force to the collection box 2, further facilitating the removal of the collection box 2 for cleaning, and then facilitating the subsequent collection of the collection box 2, further enhancing practicality.
