Description

Technical Field

[0001] The invention belongs to the technical field of waste liquid and waste material transportation, and in particular relates to waste liquid and waste material transportation equipment. Background Art

[0002] Pumps transfer the mechanical energy of the prime mover or other external energy to the liquid, increasing the liquid's energy. Pumps are primarily used to transport liquids such as water, oil, acid and alkali solutions, emulsions, suspensoids, and liquid metals. They can also transport liquid-gas mixtures and liquids containing suspended solids.

[0003] Peristaltic pumps are generally used to transport waste liquids and waste materials that are easily corrosive and contain impurities. However, during use, if the pipe material is not selected well, cracks will often appear on the pipe body during alternating deformation, and the service life will be short.

[0004] Generally, when controlling the movement of liquid particles, the structures in the pump body, such as the piston and impeller, which are located in the liquid, may get stuck between the piston and the housing, causing jamming and damage to the piston and impeller.

[0005] The present invention improves the peristaltic pump by adding a spherical plug on the inner side thereof. During the rotation of the outer pressure wheel, the outer wall of the tube body is driven to deform by squeezing. The outer wall of the tube body squeezes the spherical plug through deformation, causing the spherical plug to move, and the movement of the spherical plug promotes the flow of liquid. Through this conveying method, the tube body does not need to be greatly deformed to achieve pump transportation of the liquid, which has the beneficial effect of extending the service life of the tube body. Summary of the Invention

The shell is fixedly mounted on the upper side of the base, and a C-shaped forming shell is fixedly mounted inside the shell, and the elastic tube body is mounted inside the forming shell; an elastic output pipe is fixedly mounted on one side of the elastic tube body, and one end of the output pipe away from the elastic tube body passes through the C-shaped opening of the forming shell; the output pipe is divided into three areas: a liquid inlet channel, a mounting slide and a liquid outlet channel, and the three areas are separated from each other and respectively communicated with the elastic tube body; three spherical plugs are uniformly slidably mounted on the elastic tube body in a circumferential direction; the mounting frame is rotatably mounted in the shell, and three driving pressure wheels are uniformly fixedly mounted on the mounting frame in a circumferential direction through a mounting shaft. The three driving pressure wheels are located in an annular area in the middle of the elastic tube body and are squeezed and fitted with the elastic tube body; the three driving pressure wheels correspond to the three spherical plugs one by one; the motor is fixedly mounted on the upper side of the base, and the output shaft of the motor is fixedly connected to the mounting frame.

[0008] Two pressure blocks are symmetrically slidably installed in the shell. The two pressure blocks are located on both sides of the output pipe. The end faces of the two pressure blocks facing the output pipe are opposite to the liquid inlet channel and the liquid outlet channel in a one-to-one correspondence; the two pressure blocks are connected to the mounting frame through a trigger disc, a triangular protrusion, a connecting rod and a push rod. During the rotation of the mounting frame, the two pressure blocks will slide back and forth through the transmission of the trigger disc, the triangular protrusion, the connecting rod and the push rod; a plug is slidably installed in the mounting slide in the output pipe, and the plug is connected to the two pressure blocks through a gear and a rack transmission.

[0009] As a preferred solution, the inner arc surface of the shaping shell is in close contact with the outer arc surface of the elastic tube body, and two sides of the inner arc surface of the shaping shell extend outwards to leave a gap between them and the outer wall of the elastic tube body.

[0010] As a preferred solution, with the center of the elastic tube as the axis, assuming that the intersection of the liquid inlet channel and the elastic tube is located counterclockwise to the intersection of the liquid outlet channel and the elastic tube, then the driving pressure wheel is located counterclockwise to the corresponding spherical plug.

[0011] As a preferred solution, the trigger disc is fixedly mounted on the end of the mounting frame away from the motor output shaft, and three triangular protrusions with inclined surfaces are evenly fixedly mounted on the circumference of the trigger disc; a connecting rod is fixedly mounted on the pressure block on the same side of the two pressure blocks as the trigger disc, and a push rod is fixedly mounted on the connecting rod, and the push rod cooperates with the triangular protrusions on the trigger disc. When the trigger disc rotates together with the three driving pressure wheels, the inclined surfaces on the triangular protrusions will contact and cooperate with the push rod.

[0012] As a preferred solution, a synchronization rack is fixedly installed on each of the two pressure blocks, and a synchronization gear is rotatably installed in the housing. The synchronization gear is located between the two synchronization racks and meshes with the two synchronization racks; a spring is installed between one of the two synchronization racks and the housing.

[0016] Compared with the existing technology, the advantages of the present invention are:

[0017] 1. The present invention adds a spherical plug on the inner side of the elastic tube body. During the rotation of the outer pressure wheel, the outer wall of the elastic tube body is squeezed and driven to deform. The outer wall of the elastic tube body squeezes the spherical plug through deformation, causing the spherical plug to move, and the movement of the spherical plug promotes the flow of liquid. This driving method can prevent liquid particles from getting stuck between the spherical plug and the elastic tube body because the spherical plug is in a sliding state within the elastic tube body, thereby preventing the pump from jamming.

[0018] 2. The present invention improves the peristaltic pump by adding a spherical plug on the inner side thereof. During the rotation of the outer pressure wheel, the outer wall of the elastic tube body is driven to deform by squeezing. The outer wall of the elastic tube body squeezes the spherical plug through deformation, causing the spherical plug to move, and the movement of the spherical plug promotes the flow of liquid. Through this conveying method, the tube body does not need to be greatly deformed to realize the pump transportation of liquid, which has the beneficial effect of extending the service life of the tube body.

[0019] 3. The present invention provides a plugging block, so that when blocking the junction between the output pipe and the elastic tube body, the middle area of the elastic tube body will be blocked by the plugging block, and the two pressing blocks only need to squeeze the elastic tube body to deform slightly to block the outer area, without having to squeeze the elastic tube body significantly, thereby protecting the elastic tube body.

[0020] 4. Although the spherical plug is located in the fluid, it is not easily damaged compared to traditional pumps with blades because of its spherical structure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following embodiments or drawings are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] A waste liquid and waste material conveying equipment, such as Figure 1 、 2 , 3, 9, it includes a housing 1, a motor 2, a base 3, an elastic tube 6, a shaping shell 7, a driving pressure wheel 8, a pressure block 10, and a spherical plug 23, wherein Figure 2 、 3 As shown, the housing 1 is fixedly mounted on the upper side of the base 3, and a C-shaped shaping shell 7 is fixedly mounted inside the housing 1, and an elastic tube 6 is mounted inside the shaping shell 7; the inner arc surface of the shaping shell 7 is in close contact with the outer arc surface of the elastic tube 6, and both sides of the inner arc surface of the shaping shell 7 extend outwards to leave a gap between the outer wall surface of the elastic tube 6; Figure 4 、 8 As shown, an elastic output tube 25 is fixedly installed on one side of the elastic tube body 6, and the end of the output tube 25 away from the elastic tube body 6 passes through the C-shaped opening of the molded shell 7; Figure 9 As shown, the output tube 25 is divided into three areas: a liquid inlet channel 26, a mounting slide 27 and a liquid outlet channel 28. The three areas are separated from each other and are respectively connected to the elastic tube body 6; three spherical plugs 23 are circumferentially and evenly slidably installed in the elastic tube body 6; the mounting frame 11 is rotatably mounted in the outer shell 1, and three driving pressure wheels 8 are circumferentially and evenly fixedly mounted on the mounting frame 11 through the mounting shaft 12. The three driving pressure wheels 8 are located in the annular area in the middle of the elastic tube body 6 and are squeezed and fitted with the elastic tube body 6; the three driving pressure wheels 8 correspond one-to-one to the three spherical plugs 23; with the center of the elastic tube body 6 as the axis, assuming that the intersection of the liquid inlet channel 26 and the elastic tube body 6 is located in the counterclockwise direction of the intersection of the liquid outlet channel 28 and the elastic tube body 6, then the driving pressure wheel 8 is located in the counterclockwise direction of the corresponding spherical plug 23.

[0033] The function of the shaping shell 7 in the present invention is to provide support for the squeezed elastic tube 6. The inner arc surface of the shaping shell 7 is in close contact with the outer arc surface of the elastic tube 6. The two sides of the inner arc surface of the shaping shell 7 extend outward to leave a gap between the outer wall of the elastic tube 6. When the driving pressure wheel 8 squeezes the elastic tube 6 to deform, this gap can provide space for the squeezed portion of the deformed elastic tube 6.

[0034] When the normal spherical plug 23 does not pass through the junction of the output tube 25 and the elastic tube body 6, as shown in FIG. Figure 9 As shown, the two clamping blocks are squeezed and inserted into the elastic tube body 6 under the action of the spring 29 to form two inner grooves 24 on the elastic tube body 6. That is, the elastic tube body 6 here is squeezed inward by the two pressing blocks 10, and at this time the plug 18 is located between the two inner grooves 24 to block the space between the two inner grooves 24. That is, the squeezing and cooperation between the two pressing blocks 10 and the plug 18 forms a barrier at the intersection of the elastic tube body 6 and the output pipe 25. The inflowing liquid enters the elastic tube body 6 after passing through the liquid inlet channel 26, and the liquid in the elastic tube body 6 is discharged from the liquid outlet channel 28.

[0035] In the present invention, a plug 18 is provided, so that when blocking the junction between the output pipe 25 and the elastic tube body 6, the middle area of the elastic tube body 6 will be blocked by the plug 18, and the two pressing blocks 10 only need to squeeze the elastic tube body 6 to deform slightly to block the outer area, without having to squeeze the elastic tube body 6 significantly, thereby protecting the elastic tube body 6.

[0036] like Figure 1 、 2 As shown, the motor 2 is fixedly mounted on the upper side of the base 3, as shown in FIG. Figure 5 As shown, the output shaft of the motor 2 is fixedly connected to the mounting bracket 11; the trigger disc 9 is fixedly mounted on the end of the mounting bracket 11 away from the output shaft of the motor 2, as shown in FIG. Figure 6 As shown, three triangular protrusions 13 with inclined surfaces are evenly fixed on the circumference of the trigger disc 9; two pressing blocks 10 are symmetrically slidably installed in the housing 1, and the two pressing blocks 10 are located on both sides of the output pipe 25, as shown in FIG. Figure 4 、 9 As shown, the end surfaces of the two pressing blocks 10 facing the output pipe 25 are aligned with the liquid inlet channel 26 and the liquid outlet channel 28; Figure 7As shown, a synchronization rack 16 is fixedly mounted on each of the two pressure blocks 10, and a synchronization gear 17 is rotatably mounted in the housing 1. The synchronization gear 17 is located between the two synchronization racks 16 and meshes with the two synchronization racks 16; a spring 29 is installed between one of the two synchronization racks 16 and the housing 1; a connecting rod 15 is fixedly mounted on the pressure block 10 on the same side of the trigger disc 9 among the two pressure blocks 10, and a push rod 14 is fixedly mounted on the connecting rod 15, and the push rod 14 cooperates with the triangular protrusion 13 on the trigger disc 9. When the trigger disc 9 rotates together with the three driving pressure wheels 8, the inclined surface on the triangular protrusion 13 will contact and cooperate with the push rod 14.

[0037] like Figure 8 As shown, a plug 18 is slidably installed in the mounting slide 27 in the output pipe 25, and a first rack 19 is fixedly installed on the plug 18, and one end of the first rack 19 passes through the output pipe 25; a first gear 20 and a second gear 21 are coaxially rotatably installed in the housing 1, and the radius of the first gear 20 is greater than the radius of the first gear 20, and the first gear 20 is meshed with the first rack 19; a second rack 22 is fixedly installed on one of the two pressing blocks 10, and the second rack 22 is meshed with the second gear 21; as shown Figure 8 、 9 As shown, the plug 18 is aligned with the two pressing blocks 10 .

[0038] In the present invention, the radius of the first gear 20 is larger than that of the first gear 20 . By enlarging the radius of the gear, the block 18 can be completely slid out of the elastic tube 6 after the pressing block 10 moves downward a small distance.

[0039] like Figure 1 As shown, the housing 1 has a feed port 4 and a discharge port 5. Figure 3 As shown, the feed port 4 is communicated with the feed channel on the output pipe 25 , and the discharge port 5 is communicated with the discharge channel on the output pipe 25 .

[0040] The spherical plug 23 used in the present invention is made of a material that is elastic, wear-resistant and not easily damaged.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the scope of protection of the present invention.

[0042] Implementation method: When the pump designed by the present invention is used, the motor 2 is controlled to work, and the motor 2 drives the mounting frame 11 to rotate. The mounting frame 11 drives the three driving rollers 8 to rotate circumferentially around the center line of the mounting frame 11. The driving rollers 8 rotate and squeeze the outer wall of the elastic tube 6 to deform. The outer wall of the elastic tube 6 squeezes the spherical plug 23 through deformation, so that the spherical plug 23 moves. The movement of the spherical plug 23 promotes the flow of liquid. At the same time, the rotation of the mounting frame 11 drives the trigger disc 9 to rotate, and the rotation of the trigger disc 9 drives the triangular protrusion 1 on it 3 rotates. When the spherical plug 23 passes the junction of the output tube 25 and the elastic tube body 6, the rotation of the trigger disc 9 will first drive the triangular protrusion 13 to contact the push rod 14. The triangular protrusion 13 squeezes the push rod 14 through the inclined surface to move. The movement of the push rod 14 drives the connecting rod 15 to move. The movement of the connecting rod 15 drives the corresponding pressure block 10 to move. The movement of the pressure block 10 drives the other pressure block 10 to move through the synchronous gear 17 and the synchronous rack 16. That is, the two pressure blocks 10 will move to both sides at the same time. The movement of the pressure block 10 will drive the second rack 22 to move. The second rack 22 moves, the second gear 21 moves, the second gear 21 moves, the first gear 20 moves, the first gear 20 moves, the second rack 22 moves, and the second rack 22 moves, the plug 18 moves; when the spherical plug 23 passes through the junction of the output tube 25 and the elastic tube body 6, the two pressing blocks 10 are also just disengaged from the elastic tube body 6, and the elastic tube body 6 is reset under its own elastic action. At the same time, the plug 18 slides out of the elastic tube body 6, and the spherical plug 23 can smoothly pass through the output tube 25 and the elastic tube When the spherical plug 23 passes through the junction of the output tube 25 and the elastic tube body 6, the two pressure blocks 10 are reset under the action of the spring 29, and the push rod 14 contacts the disk surface of the trigger disk 9; at the same time, the transmission plug 18 through the first rack 19, the second rack 22, the first gear 20 and the second gear 21 slides back into the elastic tube body 6 to block the elastic tube body 6; at this time, the inflowing liquid enters the elastic tube body 6 after passing through the liquid inlet channel 26, and the liquid in the elastic tube body 6 is discharged from the liquid outlet channel 28.
