Description

Technical Field

[0001] The utility model relates to the technical field of peristaltic pumps, in particular to a double-driven eccentric tubeless peristaltic pump. Background Art

[0002] Peristaltic pumps consist of three parts: drive, pump head and hose. The main competitive advantages of peristaltic pumps are that the fluid is isolated in the pump tube, the pump tube can be quickly replaced, the fluid is reversible, dry operation is possible, and maintenance costs are low.

[0003] Existing peristaltic pumps usually use rollers to squeeze hoses to drive liquids. However, this method has a small flow rate and cannot be used to transport more liquids. It is also inefficient and takes a lot of time. Therefore, we propose a dual-drive eccentric tubeless peristaltic pump. Utility Model Content

[0004] In view of the above problems, the utility model provides a dual-drive eccentric tubeless peristaltic pump, which has the advantages of large liquid delivery flow, high efficiency and short use time.

[0005] The technical solution of the utility model is:

[0006] A dual-drive eccentric tubeless peristaltic pump comprises a motor, both ends of which are provided with mounting plates, the motor having two output shafts, eccentric wheels being fixedly mounted on the two output shafts, the two eccentric wheels being symmetrically arranged, bearings being mounted on the outer sides of the eccentric wheels, rubber soft sleeves being mounted on the outer sides of the bearings, an outer cavity shell being mounted on the outer sides of the rubber soft sleeve, and an upper cover plate being detachably connected to one side of the outer cavity shell.

[0007] In a further technical solution, a water inlet is installed on one side of the top of the outer cavity shell, and a water outlet is installed on the other side of the top of the outer cavity shell. Connecting pipes are installed on the water inlet and the water outlet, and joints are installed on the other ends of the two connecting pipes on each side.

[0008] In a further technical solution, the joint is designed as a "Y"-shaped structure.

[0009] In a further technical solution, a blocking piece is installed at the top end of the rubber soft sleeve, and the rubber soft sleeve and the blocking piece are both made of rubber material.

[0010] In a further technical solution, screws are provided on one side of the upper cover plate, and the upper cover plate and the outer cavity shell are mounted on one side of the mounting plate by means of the screws.

[0011] In a further technical solution, the eccentric wheel, the bearing and the rubber sleeve are all installed inside the outer cavity shell.

[0012] The beneficial effects of the utility model are:

[0013] The two eccentric wheels are driven to rotate by dual drive motors, and the two eccentric wheels drive the bearings to squeeze the rubber sleeve, so that the liquid enters from the water inlet and is then discharged from the water outlet. Compared with the prior art, this method of conveying liquid has a large flow rate and a fast flow rate. It utilizes dual channels to convey liquid and can adapt to more liquid conveying work. It has high work efficiency, short working time, and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0018] Example:

[0019] like Figure 1 As shown, a dual-drive eccentric tubeless peristaltic pump comprises a motor 1, both ends of the motor 1 are equipped with mounting plates 2, the motor 1 has two output shafts, eccentric wheels 3 are fixedly mounted on the two output shafts, the two eccentric wheels 3 are symmetrically arranged, a bearing 4 is mounted on the outer side of the eccentric wheel 3, a rubber soft sleeve 5 is mounted on the outer side of the bearing 4, an outer cavity shell 6 is mounted on the outer side of the rubber soft sleeve 5, one side of the outer cavity shell 6 is detachably connected with an upper cover plate 7, a water inlet is mounted on one side of the top of the outer cavity shell 6, and the outer cavity shell 6 is provided with a plurality of eccentric wheels 3. A water outlet is installed on the other side of the top, and connecting pipes 9 are installed on the water inlet and the water outlet. A joint 10 is installed at the other end of the two connecting pipes 9 on each side. The joint 10 is a "Y"-shaped structure design. A baffle is installed on the top of the rubber soft sleeve 5. The rubber soft sleeve 5 and the baffle are both made of rubber. Screws 8 are provided on one side of the upper cover plate 7. The upper cover plate 7 and the outer cavity shell 6 are installed on one side of the mounting plate 2 by screws 8. The eccentric wheel 3, bearing 4 and rubber soft sleeve 5 are all installed inside the outer cavity shell 6.

[0020] The working principle of the above technical solution is as follows:

[0021] By starting the motor 1, the two output shafts on the motor 1 respectively drive the two eccentric wheels 3 to rotate, and the eccentric wheels 3 drive the bearing 4 to squeeze the rubber soft sleeve 5 and rotate, so that the liquid enters from the water inlet, and then flows out of the water outlet through the squeezing of the bearing 4, and converges to the joint 10 through the two connecting pipes 9 to flow out, thereby improving the flow rate of the device.

[0022] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
