Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to an external filtering device for a sprinkler truck. Background Art

[0002] The existing sprinkler trucks on the market are usually not equipped with a special external filtering device. When in use, they generally have the following defects:

[0003] (1) When adding water to the tank from the tank mouth using an external water source, impurities in the water will directly enter the tank;

[0004] (2) When using the vehicle-mounted water pump to self-prime, the water suction pipe is directly placed in the water source, and the water suction pipe will sink to the mud layer at the bottom of the water source, which will inevitably suck impurities into the pipes and tanks. When impurities enter the tank, it will cause the pipe system to be blocked, thereby affecting the performance of the sprinkler truck and reducing the service life of the water pump, valves and related accessories. Utility Model Content

[0005] The purpose of the utility model is to provide an external filtering device for a sprinkler truck, so as to solve the technical problems existing in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] An external filtering device for a sprinkler truck comprises a filter mesh bag, a first supporting ring, a second supporting ring, a closing rope and a hollow floating ball. The first supporting ring is arranged at the bottom of the filter mesh bag, the second supporting ring is arranged at the neck of the filter mesh bag, the closing rope is arranged at the bag opening of the filter mesh bag, and the hollow floating ball is connected to the closing rope.

[0008] Furthermore, the outer diameter of the first support ring is larger than the inner diameter of the water tank opening of the sprinkler truck, and the outer diameter of the second support ring is smaller than the inner diameter of the water tank opening of the sprinkler truck.

[0009] Furthermore, the filter mesh bag is made of nylon.

[0010] Furthermore, the first supporting ring is made of metal or non-metal material.

[0011] Furthermore, the second supporting ring is made of metal or non-metal material.

[0012] Furthermore, the closing rope is made of nylon.

[0013] Furthermore, the first supporting ring is detachably or fixedly arranged on the inner bottom or outer bottom of the filter mesh bag.

[0014] Furthermore, the second supporting ring is detachably or fixedly arranged on the inner side or the outer side of the neck of the filter bag.

[0015] Furthermore, the closing rope can be slidably inserted into the bag opening of the filter mesh bag to open and close the bag opening of the filter mesh bag.

[0016] Furthermore, the hollow float is fixedly connected or detachably connected to the closing rope.

[0017] The external filter device for a sprinkler truck provided by the utility model has the following operating principles:

[0018] When using an external water source to add water from the water truck tank mouth, the external filtering device of the sprinkler truck provided by the utility model can be placed at the water truck tank mouth first, and then the external water source can be connected to the upper part of the water truck tank mouth. At this time, the connected external water source will be filtered by the external filtering device of the new sprinkler truck to isolate most impurities, and then enter the tank body of the sprinkler truck. In this way, the water quality entering the tank body is effectively improved, thereby effectively improving the service life of the vehicle-mounted water pump and related accessories.

[0019] When using the vehicle-mounted water pump for self-priming and adding water, the external filtering device of the sprinkler truck provided by the utility model can be connected to the hollow float first, and then one end of the suction pipe can be connected to the water suction port of the tank body using a quick connector, and the other end can be placed in the external filtering device of the sprinkler truck provided by the utility model. After that, the external filtering device of the sprinkler truck provided by the utility model can be placed in the water source. Since the external filtering device of the sprinkler truck provided by the utility model is connected with a hollow float, the external filtering device can be placed in the middle and upper layers of the water source, which can effectively prevent the water suction port of the suction pipe from sinking to the bottom of the water source and directly contacting the mud and sand layer. At the same time, the external filtering device of the sprinkler truck provided by the utility model can also effectively remove most of the dirt in the water, so that the quality of the water sucked into the tank body after filtering through the external filter is effectively improved, thereby improving the service life of the vehicle-mounted water pump and related accessories.

[0020] Compared with the prior art, the advantages of the utility model are as follows:

[0021] (1) When using an external water source to add water to the tank body from the tank mouth, the external filtering device can be placed on the tank mouth of the water truck. When the external water source adds water to the tank body from the tank mouth, most of the impurities in the external water source can be effectively isolated, so that the quality of the water entering the tank body is effectively improved.

[0022] (2) When using a vehicle-mounted water pump to self-prime and add water, the external filter device can be connected to the water inlet of the suction pipe. The external filter device can prevent the suction port of the suction pipe from directly contacting the bottom mud and sand, and can isolate most of the dirt in the water, so that the quality of the water sucked into the tank is effectively improved, thereby extending the service life of the vehicle-mounted water pump and related accessories.
