Abstract

The utility model discloses an unblock diaphragm pump of reciprocating pumps; a slurry discharge valve 7 of the unblock diaphragm pump is arranged on the lowest part of the pump cavity; a slurry feeding valve 6 is arranged close to the slurry discharge valve so that the thick and heavy particles enter the pump cavity can be discharged through the slurry discharge valve on the lowest part of the pump cavity preferably; thereby, the problem of blocking the diaphragm pump due to the solid particles is solved; a small auxiliary exhaust valve 8 and a stop valve 9 are arranged on the highest part of the pump cavity to exhaust the air in the pump cavity; the air is exhausted from the auxiliary exhaust valve 8 and the stop valve 9 when the pump operate initially; when the air is exhausted completely, the stop valve is closed to enable the diaphragm to operate normally. The unblock diaphragm pump solves the problem of blocking the diaphragm pump due to the solid particles; the unblock diaphragm pump not only can be used to replace the mortar pump which has low efficiency, high energy consumption and easily-abraded flow parts, but also can replace a part of the centrifugal pumps to reduce the energy consumption of the liquid transportation possibly because the efficiency of the reciprocating pumps is higher than the centrifugal pumps which are widely applied.

Description

Do not stop up diaphragm pump

One, technical field:

The utility model relates to a kind of diaphragm pump in the reciprocating pump, specifically a kind of diaphragm pump that do not stop up, and it can not stop up because of carrying the gathering of solid particle in pump chamber in the slip.

Two, background technique:

Existing reciprocating pump comprises that diaphragm pump all is the work pattern that the bottom enters slip, top discharge slip and air; Slip is by pump chamber the time, since the section of pump chamber greater than advance, the plasma discharge valve is also greater than the section of conveyance conduit, big and heavy particle in the slip very easily is stranded in pump chamber, just forms the obstruction of pump chamber again after assembling, thereby the use of this class pump has been subjected to very big restriction.

Three, summary of the invention:

The purpose of this utility model is to provide a kind of be in operation not can be by the diaphragm pump that big and heavy particle blocked in the slip---promptly do not stop up diaphragm pump.

For achieving the above object, the utility model is located at the extreme lower position of pump chamber with the pulp-expelling valve of diaphragm pump, and the adjacent pulp-expelling valve of slurry-inlet valve enters the big and heavy particle of pump chamber like this with slip, just can preferentially discharge, can fundamentally solve the problem that diaphragm pump is blocked by solid granulates from pulp-expelling valve; Air in the pump chamber then is to be discharged by little auxiliary exhaust valve that is located at the pump chamber extreme higher position and stop valve, treats to close stop valve after the interior air emptying of pump chamber, and diaphragm pump has promptly entered the normal operation state.

Owing to solved the gathering of solid particle in pump chamber and the normal operation problem of pump, this diaphragm pump can be used for the slip of conveyor belt solid particle; Replace with it that efficient is low, energy consumption is high, the mortar pump of flow passage components quick abrasion will have important techniques and economic implications; Again because the efficient of this class reciprocating pump is more taller than centrifugal pump with the most use, thereby it might replace a part of centrifugal pump and reduces the energy consumption that liquid is carried.

Four, description of drawings:

Fig. 1 is the structure principle chart of existing diaphragm pump;

Fig. 2 is the side view of Fig. 1;

Fig. 3 is the structure principle chart that does not stop up diaphragm pump;

Fig. 4 is the side view of Fig. 3.

Five, embodiment:

Fig. 1, Fig. 2 are the structural principle and the side views of existing diaphragm pump: motor via reducer drives eccentric mass, and the barrier film about driving by connecting rod again on two end plug is done the to-and-fro motion on the first from left right side, causes the change of active chamber (pump chamber) volume; About the bottom of two pump chambers have slurry-inlet valve, top that pulp-expelling valve is arranged, the to-and-fro motion of barrier film forces two ends, left and right sides one-way cock up and down to replace opening and closing, the slip that is transferred sucks pump chamber from the bottom slurry-inlet valve, and air in the pump chamber and slip extrude from the pulp-expelling valve on top.Because also greater than the section of conveyance conduit, the big and heavy particle in the slip is stranded in pump chamber to the section of pump chamber greater than valve, after accumulation is assembled, has just formed the obstruction to diaphragm pump naturally, the use of existing diaphragm pump has been subjected to very big restriction.

Fig. 3, Fig. 4 be not for stopping up the structural principle and side view of diaphragm pump: its basic functional principle is identical with the existing diaphragm pump of Fig. 1, Fig. 2, it drives eccentric mass 3 by motor 1 by speed reducer 2, barrier film 5 about driving by connecting rod 4 again on two end plug is done the to-and-fro motion on the first from left right side, causes the change of active chamber internal volume and force to open or close for the one-way valve of its setting to suck or extrude slip.Different is the extreme lower position that pulp-expelling valve 7 is located at pump chamber, slurry-inlet valve 6 adjacent pulp-expelling valves; The big and heavy particle that sucks pump chamber so just can preferentially be discharged from pulp-expelling valve 7, and big and heavy particle will can not assembled in pump chamber again, not have the blocked problem of diaphragm pump again yet.Air in the pump chamber then is to discharge by little auxiliary exhaust valve 8 that is located at highest order and stop valve 9, after the air in the emptying pump chamber, closes stop valve, and diaphragm pump promptly enters normal working.This diaphragm pump that do not stop up can be used for the slip of conveyor belt solid particle, replaces with it that efficient is low, energy consumption is high, the mortar pump of flow passage components quick abrasion will have important techniques and economic implications; Efficient owing to this class reciprocating pump is higher than centrifugal pump with the most use again, thereby might replace the energy consumption that a part of centrifugal pump reduces the liquid conveying.

Establish pulp-expelling valve at the pump chamber lowest order for this, near pulp-expelling valve or pump chamber one side establish slurry-inlet valve, establish the chokelesspump of auxiliary exhaust valve and stop valve in the pump chamber highest order, go for various reciprocating pumps, comprise single-acting, double-action, multiaction and various power-actuated reciprocating pump.
