Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

In order to solve the problem that receipts agent pump among the prior art leads to operating personnel and auxiliary agent contact through artifical manual pump priming, the utility model provides a pump body subassembly.

As shown in fig. 1, the pump body assembly includes a pump body 10 and a pump barrel 20, the pump body 10 has an overflowing cavity and a first communication port communicated with the overflowing cavity, and the pump body 10 is used for conveying the additives in the plurality of additive containing barrels 1 into an additive tank; the pump filling cylinder 20 is connected with the pump body 10, the pump filling cylinder 20 is communicated with the overflowing cavity through a first communication port, and pump filling liquid is stored in the pump filling cylinder 20; wherein, the pump body 10 accomplishes the pump suction operation to a dress agent bucket 1 in a plurality of dress agent buckets 1, and when the pump body 10 communicates with a dress agent bucket 1 in the other dress agent buckets 1, the pump-filling liquid in the pump-filling section of thick bamboo 20 flows into and overflows the intracavity to the pump-filling operation is carried out to pump body 10.

The application provides a pump body subassembly with irritate pump barrel 20, irritates the pump operation through irritating pump barrel 20 to pump body 10, has liberated the staff to ensure that operating personnel's is healthy.

Specifically, the pump filling cylinder 20 is connected with the pump body 10, and meanwhile, the pump filling cylinder 20 is communicated with the overflowing cavity through the first communication port on the pump body 10, so that after the pump body 10 finishes pumping operation on one of the plurality of agent containing barrels 1, in the process of communicating the pump body 10 with one of the other agent containing barrels 1, as the overflowing cavity is in a low-pressure state, the pump filling liquid in the pump filling cylinder 20 flows into the overflowing cavity, the pump body 10 is prevented from being evacuated, the working reliability of the pump body 10 is ensured, and the pump body 10 is ensured to have enough service life; in addition, because pump priming barrel 20 can carry out the pump priming operation to pump body 10 by oneself, need not artifical manual pump priming, liberated both hands, thereby when avoiding consuming great labour, still promoted the efficiency of receiving the agent of pump body subassembly, avoided operating personnel and auxiliary agent contact, thereby ensure that operating personnel's healthy can be ensured, can also avoid operating personnel to appear the unrestrained phenomenon of auxiliary agent when manual pump priming, thereby avoided the auxiliary agent to cause serious pollution to the environment.

As shown in fig. 1, the pump priming cartridge 20 is located above the pump body 10, and the priming solution in the pump priming cartridge 20 flows into the flow-through cavity under its own weight. Thus, in the process that the pump body 10 is switched to the filling agent barrel 1 communicated with the pump body, the overflowing cavity is in a low-pressure state, a small part of gas enters air from an inlet of the pump body 10, which is used for being communicated with the filling agent barrel 1, but the flowing of the filling pump liquid in the filling pump barrel 20 into the overflowing cavity under the action of the gravity of the filling pump liquid is not influenced, and the phenomenon of evacuation of the pump body 10 is avoided.

Like this, when using the pump body subassembly for the first time, open valve body 40 and make pump barrel 20 and pump body 10 communicate, adopt the mode of pump entry to carry out the pump priming, after pump body 10 starts, the first intercommunication mouth of pump body 10 fills partial pump priming liquid to the interior automatic filling of pump barrel 20, follow-up will not need the mode of pump entry pump priming once more, because fill partial pump priming liquid in pump barrel 20, the in-process of pump body 10 switching rather than the filling agent bucket 1 who communicates, the pump priming liquid in pump barrel 20 flows to overflowing the intracavity and in order to carry out the pump priming operation, after pump body 10 accomplishes the switching operation rather than the filling agent bucket 1 who communicates, pump pumping operation is carried out, can fill pump priming liquid to pump barrel 20 again automatically, so relapse, thereby avoid appearing the phenomenon of managing to find time.

It should be noted that, in the present application, when the pump body assembly is stopped, the valve body 40 is closed to disconnect the pump cartridge 20 and the pump body 10, and then the pump body 10 stops working; at the beginning of the pump body assembly, the valve body 40 is opened to communicate the cartridge 20 with the pump body 10, and the pump body 10 is activated.

It should be noted that, in the present application, the pump filling liquid is a liquid of the same type as the additive in the filling agent barrel 1. Thus, the auxiliary agent is prevented from being polluted because the auxiliary agent and the pump filling liquid are different liquids.

It should be noted that, in this application, when the agent operation need be received to the same pump body subassembly when the auxiliary agent of multiple different models, in order to avoid each auxiliary agent to appear mixing phenomenon, optionally, the pump body subassembly includes a plurality of dress agent bucket groups, and an assembly agent bucket group includes a plurality of dress agent buckets 1, and each assembly agent bucket group is used for holding the auxiliary agent of different models respectively. In this way, the operational reliability of the pump body assembly is ensured.

Optionally, the number of the pump filling cylinders 20 is multiple, the multiple pump filling cylinders 20 are all connected with the pump body 10, the multiple pump filling cylinders 20 and the multiple assembly agent barrel groups are arranged in a one-to-one correspondence manner, and each pump filling cylinder 20 is used for storing an auxiliary agent with the same type number as that in the assembly agent barrel 1 in each assembly agent barrel group. Thus, one pump cylinder 20 is ensured to correspond to one type of auxiliary agent, and the pump body assembly is ensured to respectively receive the auxiliary agents.

Of course, there are a plurality of first communication pipes 30, a plurality of first communication pipes 30 are disposed in one-to-one correspondence with the plurality of pumping cylinders 20, a plurality of valve bodies 40 are disposed, and a plurality of valve bodies 40 are disposed in one-to-one correspondence with the plurality of first communication pipes 30. Thus, the pump priming operation of each pump priming cylinder 20 is ensured to be reliable by ensuring that each pump priming cylinder 20 does not interfere with each other.

The first communication ports are plural, and the plural first communication ports and the plural first communication pipes 30 are provided in one-to-one correspondence. Thus, one communication port corresponds to one first communication pipe 30, and the phenomenon of mixing of various auxiliary agents is avoided.
