Description

Hose roller pump

The present invention relates to a hose roller pump, and more particularly, to a hose roller pump capable of real-time checking of a pump internal state by a cover formed with a state confirmation window and an inverter, and can easily count a transfer amount through the number of rotations of the rotor, The hose can be smoothly restored by the rotation of the hose formed by the roller, so that the actual amount of transfer can be improved. In addition, the lubricant It is possible to maintain the clean condition at all times, and it is possible to change quickly when repair such as damage of the hose is needed, so that it is possible to save time and cost for maintenance, Improved form of hose roller pump available It relates.

Generally, a hose pump is a motor which rotates a rotor provided with a roller on the outside thereof and rotates the roller so as to pressurize the hose which can be elastically compressed, thereby quantitatively feeding the material inside the hose. So that the pump can be a positive displacement pump because the material is completely closed between the roller and the roller constituting the rotor by the complete compression of the hose, There is a feature that a check valve is not needed when the pump is not working and is prevented.

These hose pumps are currently used in various industrial fields such as moving concrete mortar or moving food by an automated system, transferring anchovies, transporting sludge.

A hose pump for a concrete mortar is disclosed in, for example, Japanese Laid-Open Patent Publication No. 10-2018-0085666 (published on Jul. 27, 2018)

A housing main body fixedly installed on an upper surface of the base frame, the housing main body having a semi-circular running rail on an inner side wall thereof cut vertically in the middle of an ellipse; A cover coupled to the front of the housing body; A hose which is fitted in the housing so as to be in close contact with an inner wall surface of the housing and which guides the concrete mortar into one side and guide the concrete mortar into the other side; A rotor rotatably installed inside the housing and pressing the hose in one direction while rotating to press the concrete mortar; And a driving motor installed behind the housing to rotate the rotor. The hose pump for a concrete mortar according to claim 1, wherein the rotor comprises: a rotating shaft connected to an output shaft of the driving motor; A pair of rotary plates installed on the rotary shaft and rotated together therewith; And a roller disposed axially between the rotation plates so as to be rotatable about an axis perpendicular to the rotation plate, the roller comprising: A pressing roller installed at an angle of 180 degrees for pressing the hose to transfer the material therein; And a guide roller installed between the pressing rollers and for preventing the hose from being pushed back when pressed by the hose, wherein the hose has an inlet connecting tube having one end protruded toward the inside from the lower side of the housing And the other end is fixed to an outlet connecting pipe provided so as to protrude inwardly from the upper side of the housing.

However, the conventional hose pump constructed as above can not accurately count the amount of material pumped in the hose by driving the pump, so that it is cumbersome to install a separate device such as a scale for confirming the amount of transfer. In order to prevent the surface of the hose from being damaged by the pressing of the roller formed therein, lubricating means such as grease is filled, so that when the hose is damaged, all of the lubrication means is removed and the hose is repaired. There is a problem in that the workload per day is remarkably lowered.

In addition, since the roller formed on the rotor rotates naturally and the hose is compressed and deformed to move the inner material, since the hose is deformed and then restored to its original shape, it takes time to lower the pressure-feeding ability due to the late restoration, .

As the rotor 40 rotates, the roller 42 mounted on the rotor 40 rotates while pressing the hose 20 to rotate the discharge material 12, which is sucked into the hose 20, And then discharged.

At this time, the roller 42 rotates naturally from the housing 41 of the rotor 40, so that the hose 20 is rotated by the rotation of the rotor 40, Thereby preventing scratches and abrasion.

The center of the roller 42 is naturally positioned in the guide groove 421 so that the central portion of the hose 20 is positioned at the center of the guide groove 421. [ Thereby guiding the hose 20 to be accurately guided to the center portion of the roller 42, thereby ensuring stable hose pressing without shaking in the pressing process of the hose 20. [

The hose 20 pressed by the roller 42 is quickly restored to its original state by the restoring rotary shaft 43 formed at the rear of the roller 42 in accordance with the rotation direction of the rotor 40.

That is, the restoration rotary shaft 43 is coupled to the housing 41 and has a restoring shaft 435 rotatably connected to the plate 431 having the cover 434, which is the same as or smaller than the diameter before the hose 20 is compressed So that the compressed hose 20 can be quickly restored to its original shape by pressing both side surfaces of the hose 20 compressed by the roller 42 by the gap formed between the hose roller 20 and the hose roller 20, The contents introduced into the hose roller 100 can be smoothly introduced and the inflow space can be quickly secured to improve the efficiency of the hose roller pump 100.

Particularly, the restoring shaft 435 is also naturally rotated by the inner bearing 433, thereby preventing the side of the hose from being scratched or damaged.

As the rotor 40 rotates and the roller 42 and the restoration rotary shaft 43 of the rotor 40 rotate and the hose 20 is compressed and restored, .

Both end portions of the hose 20 are connected to the inflow pipe 161 and the discharge pipe 171 formed in the case 10 and the inflow pipe 161 and the discharge pipe 171 are connected to the first guide plate 16, The first guide plate 16 and the second guide plate 17 are moved forward by using the adjustment bolts 18 by being connected to the case 10 by the adjustment bolts 18 while being fixed to the second guide plates 17, Or backward to allow smooth connection to the end of the hose (20).

In addition, when back pressure is applied to the material discharged through the discharge pipe 171, the back pressure can be removed by the buffering action of the buffer tank 15, which is branched from the discharge pipe 171, .

The hose roller pump 100 according to the present invention configured as described above can easily measure the transfer amount of the material moving in the hose substantially by counting the number of revolutions of the rotor rotating in the hose roller pump through the configuration of the inverter formed on the cover In addition to being able to check the status of the rotor in real time by the state check ball, there is no lubricating means such as grease inside the hose roller pump, so that it can be easily repaired without disassembling the hose roller pump In particular, it is possible to easily manage the inside of the hose roller pump through the check hole without using a lubricating means such as grease inside the hose roller pump It is possible to manage the hose roller pump cleanly, The present invention relates to a hose roller pump, a hose roller pump, and a hose roller.
