Description

Technical Field

[0001] This invention relates to the field of material conveying technology, and in particular to a conveying pump suitable for high-viscosity clay. Background Technology

[0002] A clay conveying pump is a specialized device used to transport clay materials in a plastic or fluid state from one location to another. It is widely used in ceramic raw material preparation, building foundation treatment, tunnel slurry conveying, and mine backfilling. Traditional clay conveying pumps typically employ a screw conveyor structure, where a motor drives a shaft with helical blades to rotate inside a conveying cylinder. The thrust of the helical blades pushes the clay from the inlet to the outlet. Due to its advantages of continuous conveying, good sealing, and small footprint, this structure has become one of the mainstream devices for conveying clay materials.

[0003] However, existing clay conveying pumps have significant drawbacks when conveying high-viscosity clay. High-viscosity clay has strong adhesive properties and easily adheres to the surface of the auger blades, the inner wall of the conveying cylinder, and the outer circumference of the central shaft during conveying. As the conveying time increases, the adhesive layer gradually thickens, which not only reduces conveying efficiency but also causes local blockages in the conveying channel, and in severe cases, even leads to motor overload or equipment jamming. Currently, the common method to address this problem is to periodically stop the machine and manually open the conveying cylinder for cleaning. However, this method is labor-intensive, time-consuming, and requires frequent cleaning because high-viscosity clay can easily re-adhere, severely impacting production continuity and equipment lifespan. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the problems existing in the above and / or prior art, the present invention is proposed.

[0006] Therefore, the technical problem to be solved by the present invention is to provide a conveying pump suitable for high-viscosity clay that can effectively prevent high-viscosity clay from sticking to the spiral blades, the inner wall of the conveying cylinder and the rotating shaft during the conveying process, thereby avoiding blockage and reducing the frequency of manual cleaning.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a pump suitable for conveying high-viscosity clay, comprising: An elastic support mechanism includes a support frame, with shock-absorbing supports symmetrically installed on the left and right sides of the top of the support frame, an auxiliary support located on the upper surface of the support frame and at the right end of the left shock-absorbing support, a buffer support located on the lower right side of the support frame, and an impact component located in the middle of the top of the support frame; and...

A telescopic plate is fixedly connected to the top of each telescopic spring, and the two telescopic plates are slidably sleeved on the two limiting rods. The opposite surfaces of the two telescopic plates penetrate the outer walls of the two limiting frames and extend to a telescopic column fixedly connected to the center of the support frame. A transmission block is fixedly installed at the bottom of the telescopic column, and a striking plate is fixedly installed at the top of the telescopic column, with the striking plate positioned directly below the conveying cylinder.

[0010] As a preferred embodiment of the pump for conveying high-viscosity clay described in this invention, the auxiliary support includes inclined support plates, which are symmetrically arranged front and rear and fixedly installed at the top of the support frame. Arc-shaped support plates are fixedly installed at the top of the two inclined support plates.

[0011] As a preferred embodiment of the pump for conveying high-viscosity clay described in this invention, wherein: a first elastic pad is fixedly installed on the upper surface of the arc-shaped support plate, and the upper surface of the first elastic pad abuts against the bottom surface of the conveying cylinder; a second elastic pad is fixedly installed on the upper surface of the striking plate; both the first elastic pad and the second elastic pad are made of elastic material, the first elastic pad is used to provide buffer support when the conveying cylinder vibrates, and the second elastic pad is used to buffer the impact between the striking plate and the conveying cylinder during striking.

[0012] As a preferred embodiment of the pump for conveying high-viscosity clay described in this invention, the transmission assembly includes a mounting frame disposed on the outer side of the right end of the support frame. The right end of the conveying shaft is rotatably connected to the inner wall of the mounting frame. A drive gear is fixedly mounted on the outer surface of the conveying shaft and inside the mounting frame. A chain is meshed with the outer surface of the drive gear. A driven gear is meshed with the inner side of the bottom end of the chain. A transmission shaft is fixedly mounted in the middle of the driven gear. The left end of the transmission shaft penetrates the inner wall of the mounting frame and extends to the bottom of the transmission block, where an eccentric wheel is fixedly connected.

[0013] As a preferred embodiment of the pump for conveying high-viscosity clay described in this invention, a fixing plate is fixedly installed at the bottom of the mounting frame, a bearing seat is fixedly installed on the left side of the upper surface of the fixing plate, and the portion of the drive shaft located outside the mounting frame is rotatably connected to the bearing seat.

[0014] As a preferred embodiment of the pump for conveying high-viscosity clay described in this invention, the bottom end of the transmission block is provided with an arc-shaped groove, and the top wall of the eccentric wheel abuts against the inner wall of the arc-shaped groove.

[0015] As a preferred embodiment of the pump for conveying high-viscosity clay according to the present invention, the buffer support includes a support frame disposed below the fixed plate, a buffer cavity is provided inside the support frame, a buffer spring is fixedly installed on the inner bottom wall of the buffer cavity, and the top end of the buffer spring is fixedly connected to the bottom wall of the fixed plate. A limiting rod two is fixedly installed on the bottom wall of the buffer cavity and outside the buffer spring, a limiting block is slidably sleeved on the outer surface of the limiting rod two, and one end of the limiting block is fixedly connected to the outer wall of the fixed plate.

[0016] As a preferred embodiment of the conveying pump for high-viscosity clay described in this invention, an inlet is provided at the top left end of the conveying cylinder, and an outlet is provided at the bottom right end of the conveying cylinder.

[0017] The beneficial effects of this invention are: (1) This invention uses a single servo motor to simultaneously drive the screw conveyor mechanism and the striking assembly. Power is transmitted to the eccentric wheel through the driving gear, chain, and driven gear, which in turn drives the striking plate to intermittently strike the bottom of the conveyor cylinder. This achieves a pure mechanical linkage of "one source, two drives," eliminating the need for additional sensors or electrical control systems and significantly reducing energy consumption and manufacturing costs. At the same time, the continuous low-amplitude, high-frequency vibration can effectively break down the adhesion interface between the high-viscosity clay and the screw blades, the inner wall of the conveyor cylinder, and the conveyor shaft, making it difficult for the clay to solidify and accumulate. This greatly reduces the frequency of manual downtime for cleaning, ensuring the continuity and high efficiency of the conveying operation.

[0018] (2) The present invention incorporates a shock-absorbing support, an auxiliary support, and a buffer support on the support frame, which together form an elastic support system. The shock-absorbing support allows the conveying cylinder to generate elastic vibration during impact, while isolating the impact from being transmitted to the frame; the arc-shaped support plate and the first elastic pad in the auxiliary support provide auxiliary support for the left side of the conveying cylinder, preventing it from sagging and deforming due to excessive cantilever length; the buffer support absorbs the reverse impact of the transmission components and ensures vertical guiding accuracy through the limiting rod and limiting block. The above structure enables the entire machine to maintain stable operation under continuous impact conditions, which not only extends the service life of the equipment but also reduces vibration noise, making it particularly suitable for continuous conveying scenarios involving high viscosity and easily adherent clay.

Detailed Implementation

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0023] Example Reference Figures 1-8 This invention provides a pump suitable for conveying high-viscosity clay, including an elastic support mechanism 100 and a screw conveying mechanism disposed thereon. The elastic support mechanism 100 supports the entire screw conveying mechanism and provides buffering, vibration damping, and limiting functions when the impact assembly 105 is in operation, preventing damage to the equipment due to continuous impact. Specifically, the elastic support mechanism 100 includes a support frame 101, which serves as the basic load-bearing component of the entire equipment. It is constructed of welded steel profiles and possesses sufficient rigidity and stability. Symmetrical shock-absorbing supports 102 are mounted on the left and right sides of the top of the support frame 101. Each shock-absorbing support 102 consists of a lower mounting plate 102a fixedly connected to the support frame 101 by bolts, an elastic rubber pad 102b fixedly mounted on the upper end of the lower mounting plate 102a, and an upper mounting plate 102c fixedly mounted on the top of the elastic rubber pad 102b. The lower mounting plate 102a is used to securely fix the shock absorber 102 to the support frame 101. The elastic rubber pad 102b can elastically deform in the vertical direction to absorb impacts and vibrations from above. The upper mounting plate 102c is used to fix it to the connector 201 in the screw conveyor mechanism. With this structure, the shock absorber 102 provides elastic support for the conveyor cylinder 202 and allows the conveyor cylinder 202 to produce small up-and-down vibrations when hit, without directly transmitting severe impacts to the support frame 101.

[0024] An auxiliary support 103 is provided on the upper surface of the support frame 101, located at the right end of the left-side shock-absorbing support 102. This auxiliary support 103 includes inclined support plates 103a symmetrically arranged and fixedly installed at the top of the support frame 101. Arc-shaped support plates 103b are fixedly installed at the top of the two inclined support plates 103a. The inclined support plates 103a have a triangular or trapezoidal structure, which can distribute the load borne by the arc-shaped support plates 103b to the support frame 101, enhancing the overall rigidity of the auxiliary support 103. A first elastic pad 103c is fixedly installed on the upper surface of the arc-shaped support plate 103b, and the upper surface of the first elastic pad 103c abuts against the bottom surface of the conveying cylinder 202. The first elastic pad 103c is made of wear-resistant rubber or polyurethane elastomer material, possessing appropriate hardness and resilience. When the conveyor cylinder 202 vibrates under the impact, the first elastic pad 103c can absorb some of the vibration energy and provide auxiliary support for the bottom left side of the conveyor cylinder 202, preventing the conveyor cylinder 202 from drooping too much due to the excessive length of the cantilever, and ensuring that the conveyor cylinder 202 always maintains a horizontal or slightly inclined working posture.

[0025] A buffer support 104 is provided on the lower right side of the support frame 101. The buffer support 104 includes a support frame 104a located below the transmission assembly 205. The support frame 104a is fixedly installed on the ground or a work platform, and has a buffer cavity 104b inside. A buffer spring 104c is fixedly installed on the inner bottom wall of the buffer cavity 104b, and the top end of the buffer spring 104c is fixedly connected to the bottom wall of the fixed plate 205g in the transmission assembly 205. The buffer spring 104c can undergo compressive deformation when the transmission assembly 205 is subjected to a reaction force from the eccentric wheel 205f, absorbing impact energy and preventing the vibration of the transmission assembly 205 from being directly transmitted to the support frame 101. Simultaneously, a limiting rod 104d is fixedly installed on the bottom wall of the buffer cavity 104b, located outside the buffer spring 104c. A limiting block 104e is slidably sleeved on the outer surface of the limiting rod 104d, and one end of the limiting block 104e is fixedly connected to the outer wall of the fixed plate 205g. The limiting rod 104d and the limiting block 104e together constitute a vertical guiding and limiting structure, ensuring that the fixed plate 205g can only move up and down in the vertical direction during vibration, and will not shift horizontally or rotate, thereby ensuring the motion accuracy of the transmission shaft 205e and the eccentric wheel 205f.

[0026] A striking component 105 is provided at the center of the top of the support frame 101. This striking component 105 is used to apply intermittent knocking to the bottom of the conveying cylinder 202 to generate continuous micro-vibration, thereby breaking the adhesion between the high-viscosity clay and the metal surface. The striking component 105 includes limiting frames 105a symmetrically installed on the front and rear sides of the top of the support frame 101. Each limiting frame 105a has a telescopic groove 105b inside. A limiting rod 105c is fixedly installed at the center of each telescopic groove 105b. A telescopic spring 105d is sleeved on the outer surface of the limiting rod 105c. The bottom end of the telescopic spring 105d is fixedly connected to the bottom wall of the telescopic groove 105b. A telescopic plate 105e is fixedly connected to the top end of the telescopic spring 105d. The telescopic plate 105e is slidably sleeved on the limiting rod 105c. Limiting rod 105c ensures that the telescopic plate 105e can only slide vertically up and down, preventing it from tilting or jamming. Telescopic spring 105d is always compressed or stretched, providing a restoring force for the telescopic plate 105e. The opposing surfaces of the two telescopic plates 105e penetrate the outer walls of the two limiting frames 105a and extend to the center of the support frame 101. A telescopic column 105f is fixedly connected between them. A transmission block 105g is fixedly installed at the bottom of the telescopic column 105f, and a striking plate 105h is fixedly installed at the top of the telescopic column 105f, positioned directly below the conveyor cylinder 202. The transmission block 105g receives the driving force from the eccentric wheel 205f and converts it into the reciprocating motion of the telescopic column 105f. A second elastic pad 105i is fixedly installed on the upper surface of the striking plate 105h. The second elastic pad 105i is also made of elastic material. Its function is to buffer the rigid impact between the striking plate 105h and the bottom of the conveying cylinder 202 when the striking plate 105h moves upward and contacts the bottom of the conveying cylinder 202, reduce metal collision noise, and extend the service life of the striking plate 105h and the conveying cylinder 202.

[0027] The above describes the detailed structure of the elastic support mechanism 100 and its various components. The following describes the screw conveyor mechanism and its transmission relationship.

[0028] The screw conveyor mechanism includes connecting parts 201 fixedly mounted on the upper surfaces of two shock-absorbing supports 102. Connecting parts 201 have an L-shaped plate structure; their lower ends are bolted to the upper mounting plate 102c of the shock-absorbing supports 102, and their upper ends are bolted to the outer wall of the conveying cylinder 202. The conveying cylinder 202 is fixedly mounted between the two connecting parts 201. The conveying cylinder 202 is a cylindrical shell made of wear-resistant steel, and its inner wall is polished or coated with a wear-resistant coating to reduce clay adhesion. A servo motor 203 is fixedly mounted on the left end of the left connecting part 201. The servo motor 203 serves as the sole power source for the entire device, providing stable torque and speed. The output end of the servo motor 203 is connected to a conveying shaft 204 via a coupling. The coupling is a flexible coupling to compensate for minor coaxiality deviations between the conveying shaft 204 and the motor output shaft caused by vibration. The right end of the conveying shaft 204 passes through the conveying cylinder 202 and extends to the outside of the right-side connector 201, and a transmission assembly 205 is driven to this end. A spiral conveying blade 206 is fixedly mounted on the outer surface of the conveying shaft 204, and the spiral conveying blade 206 is disposed inside the conveying cylinder 202. The spiral conveying blade 206 is made of continuous spiral steel plate welded to the conveying shaft 204. Its pitch and diameter are optimized according to the conveying volume and viscosity of the clay, and it can rotate under the drive of the servo motor 203, pushing the high-viscosity clay entering the conveying cylinder 202 from the feed port 202a at the left end to the discharge port 202b at the right end.

[0029] The transmission assembly 205 is located on the outer right side of the support frame 101. Its function is to transmit the rotational power of the conveyor shaft 204 to the striking assembly 105, achieving dual-drive from a single source. Specifically, the transmission assembly 205 includes a mounting frame 205a, which is a detachable, enclosed box structure used to house and protect the internal gear and chain mechanism. The right end of the conveyor shaft 204 is rotatably connected to the inner wall of the mounting frame 205a via bearings to ensure smooth rotation of the conveyor shaft 204. A drive gear 205b is fixedly mounted on the outer surface of the conveyor shaft 204 and inside the mounting frame 205a. The drive gear 205b rotates synchronously with the conveyor shaft 204. A chain 205c is meshed with the outer surface of the drive gear 205b. The chain 205c is a roller chain with high tensile strength and wear resistance. A driven gear 205d is meshed with the inner side of the bottom end of the chain 205c. A drive shaft 205e is fixedly installed at the center of the driven gear 205d. The left end of the drive shaft 205e passes through the inner wall of the mounting frame 205a and extends to the bottom of the transmission block 105g, where an eccentric wheel 205f is fixedly connected. By appropriately selecting the gear ratio between the driving gear 205b and the driven gear 205d, the rotational speed of the eccentric wheel 205f can be adjusted to match the rotational speed of the screw conveyor blade 206, thereby achieving the optimal striking frequency.

[0030] To ensure the stability and reliability of the drive shaft 205e during rotation, a fixing plate 205g is fixedly installed at the bottom of the mounting frame 205a. A bearing seat 205h is fixedly installed on the left side of the upper surface of the fixing plate 205g, and the portion of the drive shaft 205e located outside the mounting frame 205a is rotatably connected to the bearing seat 205h. The bearing seat 205h contains a rolling bearing capable of withstanding the radial load and a certain axial load of the drive shaft 205e. Simultaneously, the fixing plate 205g also serves as the upper connection point of the buffer support 104, with its bottom connected to the buffer spring 104c and the limiting rod 104d, allowing the entire transmission assembly 205 to float vertically, thereby adapting to the reaction force generated when the impact assembly 105 operates.

[0031] The power transmission between the striking component 105 and the transmission component 205 is achieved through the eccentric wheel 205f and the transmission block 105g. The bottom end of the transmission block 105g has an arc-shaped groove 105g1, and the top wall of the eccentric wheel 205f abuts against the inner wall of the arc-shaped groove 105g1. When the transmission shaft 205e drives the eccentric wheel 205f to rotate, because the geometric center of the eccentric wheel 205f does not coincide with the center of rotation, its outer contour periodically pushes the bottom of the arc-shaped groove 105g1, causing the transmission block 105g to move upwards. After the eccentric wheel 205f passes its highest point, the transmission block 105g moves downwards under the restoring force of the telescopic spring 105d. This process repeats, causing the transmission block 105g to drive the telescopic column 105f and the striking plate 105h to reciprocate up and down. The striking plate 105h strikes the bottom of the conveyor cylinder 202 at a certain frequency and amplitude. The striking frequency is determined by the rotational speed of the servo motor 203 and the transmission ratio between the drive gear 205b and the driven gear 205d, while the striking amplitude depends on the eccentricity of the eccentric wheel 205f.

[0032] A feed inlet 202a is located at the top left end of the conveying cylinder 202 for feeding in high-viscosity clay to be conveyed; a discharge outlet 202b is located at the bottom right end of the conveying cylinder 202 for discharging the clay after conveying and vibration anti-sticking treatment. The size and position of the feed inlet 202a and the discharge outlet 202b are designed according to the actual working conditions. The feed inlet 202a is usually funnel-shaped to facilitate the smooth entry of clay; the discharge outlet 202b is inclined downwards or connected to subsequent pipelines to ensure smooth discharge.

[0033] Overall working principle: When this pump is working, the servo motor 203 is started first. The servo motor 203 drives the conveyor shaft 204 to rotate through the coupling. The conveyor shaft 204 drives the spiral conveyor blades 206 to rotate inside the conveyor cylinder 202. On the other hand, it drives the transmission shaft 205e to rotate through the drive gear 205b, chain 205c and driven gear 205d at the right end of the conveyor shaft 204. The eccentric wheel 205f at the end of the transmission shaft 205e rotates accordingly. Since its eccentric profile abuts against the arc groove 105g1 at the bottom of the transmission block 105g, the eccentric wheel 205f pushes the transmission block 105g upward once for each rotation. Then, under the tension or compression of the telescopic spring 105d, it resets, causing the transmission block 105g to drive the telescopic column 105f and the striking plate 105h to complete one up-and-down reciprocating motion. The second elastic pad 105i at the top of the striking plate 105h strikes the bottom of the conveyor cylinder 202 upward. The impact force causes the conveyor cylinder 202 to momentarily move upward. However, due to the elastic support of the shock-absorbing support 102 and the auxiliary support 103, the conveyor cylinder 202 does not move rigidly upward, but rather experiences a small vibration. As the eccentric wheel 205f rotates continuously, the striking plate 105h repeatedly strikes the bottom of the conveyor cylinder 202 at a fixed frequency, causing the entire conveyor cylinder 202 and its internal spiral conveying blades 206 and conveying shaft 204 to be in a state of continuous micro-vibration.

[0034] Meanwhile, the high-viscosity clay fed into the feed inlet 202a is gradually moved towards the discharge outlet 202b by the screw conveyor blades 206. During this movement, because the conveyor cylinder 202, screw conveyor blades 206, and conveyor shaft 204 are constantly in a state of micro-vibration, the adhesion interface between the clay and the metal surface is continuously broken by the vibration. The unconsolidated clay layer detaches from the blades and cylinder wall under the action of inertial force and shear force, and returns to the material flow. This effectively prevents the gradual accumulation and blockage of clay. In addition, the first elastic pad 103c in the auxiliary support 103 provides auxiliary buffering when the conveyor cylinder 202 vibrates, preventing excessive sagging deformation on the left side of the conveyor cylinder 202 due to impact; the buffer support 104 absorbs the reverse impact of the transmission component 205, ensuring that the eccentric wheel 205f and the transmission block 105g are always in reliable contact; and the shock-absorbing support 102 isolates the vibration of the whole machine from the support frame 101, preventing the vibration from being transmitted to the ground or other connected equipment.

[0035] In summary, this conveying pump uses only one servo motor 203 to simultaneously achieve continuous clay conveying and anti-sticking impact on the cylinder, resulting in a compact structure, low energy consumption, and high reliability. Due to the continuous impact vibration, it is difficult for clay to form a thick adhesion layer on the spiral blades 206, the inner wall of the conveying cylinder 202, and the conveying shaft 204, thus greatly reducing the frequency of manual downtime for cleaning and significantly improving the continuity and efficiency of high-viscosity clay conveying operations.
