Description

Technical Field

[0001] The utility model relates to the technical field of filter sewage discharge collection, and more specifically, to a filter sewage discharge collection device. Background Technique

[0002] Agricultural and engineering machinery such as tractors are often used for field operations. After the filter on them works for a certain period of time, the pollutants filtered and separated in the water collecting cup need to be discharged. In order to protect the environment, according to national environmental protection laws and regulations, oil-containing pollutants belong to hazardous waste and need to be collected and centrally treated. At this time, a filter sewage discharge collection device, that is, a sewage discharge collection bag, is required.

[0003] When the existing sewage discharge collection bag is in use, it is necessary for personnel to manually dock the bag mouth of the collection bag with the sewage discharge port of the filter, and then hold it fixed by personnel, which will increase the labor intensity of the personnel. Moreover, if the holding force of the personnel is not enough, it is very easy to fall off, which will cause the pollutants to spill, resulting in the inconvenience of using the sewage discharge collection bag. In view of this, we propose a filter sewage discharge collection device. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a filter sewage discharge collection device to solve the technical problem that the bag mouth of the current sewage discharge collection bag is not convenient for automatic quick connection with the sewage discharge port of the filter.

[0005] To solve the above technical problems, the utility model provides the following technical solutions: a filter sewage discharge collection device, including a sewage discharge collection bag, a bag mouth is arranged at the top of the sewage discharge collection bag, a quick connection structure is arranged at the top of the bag mouth, the quick connection structure includes a connection structure and a quick connector, the connection structure is fixedly connected with the bag mouth, the quick connector includes a docking sleeve, and a number of groups of fastening structures are arranged equidistantly around the top of the docking sleeve;

[0006] A frustum-shaped through hole is opened at the inner bottom of the docking sleeve, and a closing structure is arranged inside the docking sleeve.

[0007] The utility model is provided with a quick connection structure. The connection structure of the quick connection structure is connected and fixed to the bag mouth of the sewage collection bag. Then, the quick connection structure can be quickly and automatically docked and fixed to the sewage outlet of the filter through a quick connector. The docking sleeve of the quick connector is inserted and docked with the sewage outlet of the filter. As the sewage outlet of the filter is inserted into the docking sleeve, the triangular ring around the sewage outlet of the filter will push the fastening block in the fastening structure towards the installation sleeve. When the sewage outlet of the filter is completely inserted into the docking sleeve, under the cooperation of the first spring, the fastening block is pushed back to its original position. At this time, the fastening block is fastened above the triangular ring around the sewage outlet of the filter, thus realizing the automatic docking and fixing with the sewage outlet of the filter, eliminating the need for manual holding and fixation, and greatly improving the convenience of using the sewage collection bag. The utility model also has a designed closing structure, and a frustum-shaped through hole is opened at the bottom of the docking sleeve. When the sewage outlet of the filter is inserted into the docking sleeve for connection, the sewage outlet of the filter will press down the elastic stretching frame. At this time, the elastic stretching frame will drive the frustum-shaped sealing seat to move downward synchronously. At this time, the frustum-shaped sealing seat disengages from the frustum-shaped through hole, and then the pollutants discharged from the sewage outlet of the filter can smoothly pass through the frustum-shaped through hole and enter the bag mouth. Finally, the pollutants fall into the sewage collection bag for collection. After the sewage discharge is completed, the sewage outlet of the filter is separated from the docking sleeve, and then the elastic stretching frame drives the frustum-shaped sealing seat to return to its original position. At this time, the frustum-shaped sealing seat will snap into the frustum-shaped through hole, thus achieving a sealing effect and preventing the pollutants inside the sewage collection bag from flowing out. Moreover, since both the frustum-shaped sealing seat and the frustum-shaped through hole are frustum-shaped, when the frustum-shaped sealing seat is impacted by the pollutants inside the sewage collection bag, it will only make the sealing effect of the frustum-shaped sealing seat on the frustum-shaped through hole better, effectively avoiding the situation of poor sealing between the frustum-shaped sealing seat and the frustum-shaped through hole, and thus realizing the automatic sealing effect of the bag mouth and further improving the convenience of using the sewage collection bag.

The frustum-shaped sealing seat is arranged at the bottom of the elastic stretching frame, and the frustum-shaped sealing seat is located inside the frustum-shaped through hole.

[0009] Preferably, a sealing sleeve is arranged around the frustum-shaped sealing seat. Both the frustum-shaped sealing seat and the frustum-shaped through hole are arranged with the large end facing down and the small end facing up.

[0010] Preferably, the elastic stretching frame includes a circular ring, a connecting rod, and a cylinder. The cylinder is arranged at the center of the top of the frustum-shaped sealing seat. The circular ring is arranged at the top end of the cylinder through the connecting rod. A plurality of groups of second springs are equidistantly arranged around the bottom of the circular ring, and the bottom ends of the second springs are connected to the inner bottom of the docking sleeve.

[0011] Preferably, the connection structure includes an external thread pipe and an internal thread sleeve. The external thread pipe is arranged at the bottom of the docking sleeve, and the internal thread sleeve is screwed onto the external thread pipe. The bottom of the external thread pipe is a first frustum section, and the bottom of the internal thread sleeve is a second frustum section. Both the first frustum section and the second frustum section are arranged with the smaller head facing downwards and the larger head facing upwards.

[0012] Preferably, the fastening structure includes a mounting sleeve, a first spring, a fastening block, and a pull rod. The mounting sleeve is arranged on the docking sleeve. The fastening block is arranged in the mounting sleeve through the first spring, and the fastening block is located inside the docking sleeve. The fastening block is triangular in shape. The pull rod is arranged on one side of the fastening block, and one end of the pull rod penetrates to the outside of the mounting sleeve.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. Through the designed quick-connection structure of the present utility model, the connection structure of the quick-connection structure is connected and fixed to the bag mouth of the sewage collection bag. Then, the quick-connection structure can be quickly and automatically docked and fixed with the sewage outlet of the filter through the quick connector. The docking sleeve of the quick connector is inserted and docked with the sewage outlet of the filter. As the sewage outlet of the filter is inserted into the inside of the docking sleeve, at this time, the triangular ring around the sewage outlet of the filter will push the fastening block in the fastening structure into the mounting sleeve. When the sewage outlet of the filter is completely inserted into the inside of the docking sleeve, at this time, with the cooperation of the first spring, the fastening block is pushed to reset. At this time, the fastening block is buckled above the triangular ring around the sewage outlet of the filter, thereby realizing the automatic docking and fixing with the sewage outlet of the filter, without the need for personnel to hold and fix it, greatly improving the convenience of using the sewage collection bag, and solving the technical problem that the bag mouth of the current sewage collection bag is not convenient for automatic quick connection with the sewage outlet of the filter. Therefore, the present utility model has the advantage of more convenient use.

[0015] 2. The utility model also adopts a designed closing structure, and a frustum-shaped through hole is opened at the bottom of the docking sleeve. When the sewage discharge port of the filter is inserted into the inside of the docking sleeve for connection, the sewage discharge port of the filter will press down the elastic stretching frame at this time. At this time, the elastic stretching frame will drive the frustum-shaped sealing seat to move downward synchronously. At this time, the frustum-shaped sealing seat disengages from the frustum-shaped through hole. Then, the pollutants discharged from the sewage discharge port of the filter can smoothly pass through the frustum-shaped through hole and enter the bag mouth. Finally, the pollutants fall into the sewage collection bag for collection. When the sewage discharge is over, the sewage discharge port of the filter is separated from the docking sleeve at this time. Then, the elastic stretching frame drives the frustum-shaped sealing seat to reset. At this time, the frustum-shaped sealing seat will snap into the inside of the frustum-shaped through hole, thereby achieving a sealing effect and preventing the pollutants inside the sewage collection bag from flowing out. Moreover, because both the frustum-shaped sealing seat and the frustum-shaped through hole are arranged with the large head facing down and the small head facing up, when the frustum-shaped sealing seat is impacted by the pollutants inside the sewage collection bag, it will only make the sealing effect of the frustum-shaped sealing seat on the frustum-shaped through hole better, effectively avoiding the situation of poor sealing between the frustum-shaped sealing seat and the frustum-shaped through hole. Thus, the automatic sealing effect of the bag mouth can be achieved, further improving the convenience of using the sewage collection bag. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the frustum-shaped plugging seat 9 is pressed into the frustum-shaped through hole 501 for sealing.

[0028] Working principle: This embodiment provides a filter sewage collection device. First, when draining sewage from the filter, the docking sleeve 5 is inserted and docked with the sewage outlet of the filter. As the sewage outlet of the filter is inserted into the inside of the docking sleeve 5, the triangular ring around the sewage outlet of the filter will push the fastening block 603 into the mounting sleeve 601. When the sewage outlet of the filter is completely inserted into the inside of the docking sleeve 5, under the cooperation of the first spring 602, the fastening block 603 is pushed back to its original position. At this time, the fastening block 603 is buckled above the triangular ring around the sewage outlet of the filter, thus realizing automatic docking and fixing with the sewage outlet of the filter, eliminating the need for manual holding and fixing, and greatly improving the convenience of using the sewage collection bag 1;

[0029] Secondly, when the connecting structure 3 is connected to the bag mouth 101, first unscrew the internal thread sleeve 303 and put it on the bag mouth 101, then insert the external thread tube 301 into the bag mouth 101, and then screw the internal thread sleeve 303 onto the external thread tube 301 again.

Through the setting of the connecting structure 3, the sewage collection bag 1 can be freely replaced, and thus the quick-connection structure 2 can be reused;

[0030] Secondly, when the sewage outlet of the filter is inserted into the inside of the docking sleeve 5 for connection, the sewage outlet of the filter will press down the elastic stretching frame 8 at this time. At this time, the elastic stretching frame 8 will drive the conical plugging seat 9 to move downward synchronously. At this time, the conical plugging seat 9 disengages from the conical through hole 501, and then the pollutants discharged from the sewage outlet of the filter can smoothly enter the bag mouth 101 through the conical through hole 501. Finally, the pollutants fall into the sewage collection bag 1 for collection. When the sewage discharge is over, the sewage outlet of the filter is separated from the docking sleeve 5, and then the elastic stretching frame 8 drives the conical plugging seat 9 to return to its original position. At this time, the conical plugging seat 9 and the sealing sleeve 901 will be stuck into the inside of the conical through hole 501, thus realizing the sealing effect and preventing the pollutants inside the sewage collection bag 1 from flowing out;

[0031] Finally, because both the conical plugging seat 9 and the conical through hole 501 are arranged with the large head facing down and the small head facing up, when the conical plugging seat 9 is impacted by the pollutants inside the sewage collection bag 1, it will only make the sealing effect of the conical plugging seat 9 on the conical through hole 501 better, effectively avoiding the situation of poor sealing between the conical plugging seat 9 and the conical through hole 501, and thus realizing the automatic sealing effect of the bag mouth 101, further improving the convenience of using the sewage collection bag 1.
