Abstract
Description
Technical Field
[0001] This utility model relates to the field of sludge transfer technology, specifically to a material receiving and transfer device for a sludge screw pump. Background Technology
[0002] In the field of sludge transfer technology, screw pumps are commonly used sludge transfer equipment, and their sludge receiving stage is crucial for efficient sludge transfer. Currently, most sludge plants use cylindrical containers as receiving containers when processing sludge transferred inside screw pumps. The operation process is as follows: after the cylindrical container has received the sludge, it is transported manually or using simple transport tools to a centralized sludge dumping site for unloading.
[0003] However, in practice, for safety reasons, sludge dumping outlets are usually located on an operating platform with a certain height and width above the ground. This spatial layout results in a significant height difference between the ground and the dumping outlet. Consequently, during sludge dumping operations, workers must first lift the sludge-filled drum onto the platform on one side of the dumping outlet, and then manually dump the sludge from the platform. Furthermore, the drum's structural design is not conducive to dumping from heights, increasing the difficulty and labor intensity of manual operation and making it easy for sludge residue to remain, hindering complete dumping. Therefore, residual sludge not only wastes materials but also significantly increases the workload of cleaning and maintaining the drum, reducing the overall efficiency of sludge dumping and treatment. Utility Model Content
[0004] This invention provides a material receiving and transfer device for sludge screw pumps to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] A material receiving and transfer device for a sludge screw pump includes a counterweight base frame, a roller assembly mounted on the bottom of the counterweight base frame, a sliding assembly fixedly mounted on the top of the counterweight base frame, a support plate fixedly connected to the top of the sliding assembly, a carriage provided on the top of the support plate, a handle fixedly connected to the surface of the carriage, one side of the bottom of the carriage being movably connected to one end of the support plate, and a folding spring bracket movably connected to the bottom of the carriage, one end of the folding spring bracket being movably connected to the support plate, and a locking mechanism connected to one side of the counterweight base frame, the locking mechanism and the handle being located on the same side of the carriage.
[0007] Preferably, the sliding assembly includes a guide rail fixedly mounted on the counterweight base and a slider fixedly mounted on the support plate. The slider is slidably connected to the guide rail, and there are two guide rails symmetrically arranged on the top of the counterweight base.
[0008] Preferably, each of the guide rails is provided with a stop block at both ends, and the stop block is fixedly installed on the top of the counterweight base frame.
[0009] Preferably, the locking mechanism includes a first guide seat connected to the counterweight base frame, a locking rod movably passing through the first guide seat, a first recessed block connected to the support plate, and a second recessed block fixedly connected to the outer surface of the carriage. The locking rod is used to engage with the recesses of the first and second recessed blocks.
[0010] Preferably, the locking mechanism further includes a second guide seat connected to the counterweight base frame, a limiting ring connected to the outer wall of the locking rod, and a spring member sleeved on the outside of the locking rod, wherein the limiting ring is brought closer to the second guide seat by the force of the spring member.
[0011] Preferably, the spring is disposed between the first guide seat and the limiting ring, and the spring is a tension spring.
[0012] Preferably, the spring is disposed between the second guide seat and the limiting ring, and the spring is a tension spring.
[0013] Preferably, the roller assembly includes two directional wheels and two omnidirectional wheels, the omnidirectional wheels are equipped with foot brakes, and the two directional wheels are located at the bottom front end of the counterweight base frame, and the two omnidirectional wheels are located at the bottom rear end of the counterweight base frame.
[0014] Preferably, a rotating groove is provided on the front end face of the carriage, and a baffle is rotatably connected in the rotating groove.
[0015] Preferably, a hollow section is provided between the two guide rails, and the folding spring bracket is disposed in the hollow section after being stored.
[0016] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:
[0017] In this invention, by mounting the carriage on a counterweight base, the carriage can flexibly slide towards the sludge dumping outlet with the help of guide rails and sliders. When the carriage slides into position and tilts, the synergistic action of the folding spring bracket and baffle ensures the stability of the carriage during the dumping process, allowing the sludge inside to be completely dumped. Therefore, compared to traditional solutions, this invention eliminates the need for manual lifting of the container full of sludge before dumping, greatly reducing labor costs and improving operational convenience. Furthermore, unlike common cylindrical structures, this invention facilitates complete dumping of sludge, effectively avoiding sludge residue and significantly improving sludge treatment efficiency, demonstrating its practicality.

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0027] like Figures 1-6As shown, this utility model provides a material receiving and transfer device for a sludge screw pump, including a counterweight base frame 1. A roller assembly is installed at the bottom of the counterweight base frame 1, and a sliding assembly is fixedly installed at the top of the counterweight base frame 1. A support plate 2 is fixedly connected to the top of the sliding assembly, and a carriage 3 is provided on the top of the support plate 2. A handle 4 is fixedly connected to the surface of the carriage 3. One side of the bottom of the carriage 3 is movably connected to one end of the support plate 2, and a folding spring bracket 5 is movably connected to the bottom of the carriage 3. One end of the folding spring bracket 5 is movably connected to the support plate 2, and a locking mechanism 6 is connected to one side of the counterweight base frame 1. The locking mechanism 6 and the handle 4 are located on the same side of the carriage 3, and the counterweight part of the counterweight base frame 1 is close to the locking mechanism 6.
[0028] It should be noted that the folding spring bracket 5 is an existing technical structure, and this solution does not modify its structure. Furthermore, the folding spring bracket 5 can be purchased commercially by those skilled in the art. It is further emphasized that the folding spring bracket 5 mainly includes a long bracket and a short bracket movably connected to the long bracket, with a spring connected to both the long and short brackets. For stability considerations, this solution uses two folding spring brackets 5, and a connecting rod is connected to the short brackets of both folding spring brackets 5. The specific method can be referenced from existing folding frame designs for mobile stages.
[0029] Combination Figure 1 As shown, as a further step, the roller assembly includes two directional wheels 10 and two omnidirectional wheels 11. Foot brakes are installed on the omnidirectional wheels 11. The two directional wheels 10 are located at the front bottom of the counterweight base 1, and the two omnidirectional wheels 11 are located at the rear bottom of the counterweight base 1. Through the cooperation of the omnidirectional wheels 11 and the foot brakes, the mud-collecting trolley can be moved flexibly to a designated position, and with the help of the foot brakes, it can be parked stably.
[0030] Combination Figure 3 As shown, as a further step, the sliding assembly includes a guide rail 7 fixedly mounted on the counterweight base 1 and a slider 8 fixedly mounted on the support plate 2. The slider 8 is slidably connected to the guide rail 7, and there are two guide rails 7, symmetrically arranged on the top of the counterweight base 1. The two symmetrically arranged guide rails 7 and slider 8, when working together, not only ensure the smooth movement of the support plate 2, but also its stability during movement, thus providing a practical function.
[0031] Each guide rail 7 has a stop block 9 at both ends, which is fixedly installed on the top of the counterweight base frame 1. The stop block 9 is designed to restrict the movement of the slider 8, thereby limiting the movement distance of the support plate 2. After the support plate 2 is in place, the operator can use the handle 4 to flip up the carriage 3, causing the sludge to be poured into the sludge dumping port. There is no need to manually lift the container full of sludge to a certain height before dumping, which reduces labor consumption and improves the convenience of operation. At the same time, the structural design of the carriage 3 in this solution is different from the cylindrical structure, which makes it easier to completely dump the sludge, effectively avoiding the problem of sludge residue and greatly improving the sludge treatment efficiency.
[0032] Combination Figure 3 and Figure 5 As shown, as a further step, a hollow section is provided between the two guide rails 7. The folding spring bracket 5 is placed in the hollow section after being stored. When the folding spring bracket 5 is placed in the hollow section, the bottom surface of the carriage 3 can be completely attached to the support plate 2, ensuring that the carriage 3 can be locked by the locking mechanism 6, and ensuring the stability of the carriage 3 when it does not tip over.
[0033] Combination Figure 5 and Figure 6 As shown, as a further step, a rotating groove is provided on the front surface of the carriage 3, and a baffle 12 is rotatably connected in the rotating groove. After the support plate 2 slides into place, the support plate 2 can be partially positioned above the width platform. Then, when the carriage 3 is flipped up and the folding spring bracket 5 is fully extended, the baffle 12 can be perpendicular to the front surface of the carriage 3. Thus, the baffle 12, which is perpendicular to the front surface of the carriage 3, can be used to fit against the inner wall of the dumping port, thereby stabilizing the carriage 3 and preventing the counterweight base frame 1 from moving backward during the sludge dumping process, ensuring the stability of the carriage 3 when dumping sludge.
[0034] Combination Figure 3 and Figure 4 As shown, as a further step, the locking mechanism 6 includes a first guide seat 61 connected to the counterweight base frame 1, a locking rod 62 movably passing through the first guide seat 61, a first recessed block 63 connected to the support plate 2, and a second recessed block 64 fixedly connected to the outer surface of the carriage 3. The locking rod 62 is used to engage with the recesses of the first recessed block 63 and the second recessed block 64. The locking rod 62 is an L-shaped rod with a horizontal section and a vertical section. The top of the second recessed block 64 has a recessed groove. When the vertical section of the locking rod 62 is located in the second recessed block 64 and the horizontal section is located in the recessed groove, it can prevent the locking rod 62 from shaking.
[0035] Combination Figure 4As shown, as a further step, the locking mechanism 6 also includes a second guide seat 65 connected to the counterweight base frame 1, a limiting ring 66 connected to the outer wall of the locking rod 62, and a spring member 67 sleeved on the outside of the locking rod 62. The limiting ring 66 is close to the second guide seat 65 by the force of the spring member 67.
[0036] In one embodiment, a spring 67 is disposed between the first guide seat 61 and the limiting ring 66, and the spring 67 is a tension spring. Thanks to the tension spring design, when the locking rod 62 is raised and its lateral section is placed in the recessed groove at the top of the second recessed block 64, the force of the tension spring causes the locking rod 62 to remain stably in the recessed groove, thus locking the carriage 3. When the lateral section of the locking rod 62 is rotated away from the top of the second recessed block 64, the force of the tension spring causes the locking rod 62 to move downwards, thus unlocking the carriage 3.
[0037] In another embodiment, a spring 67 is disposed between the second guide seat 65 and the limiting ring 66, and the spring 67 is a tension spring. Thanks to the tension spring design, when the locking rod 62 is raised and its lateral section is placed in the recessed slot at the top of the second recessed block 64, the force of the tension spring causes the locking rod 62 to remain stably in the recessed slot, thus locking the carriage 3. When the lateral section of the locking rod 62 is rotated away from the top of the second recessed block 64, the force of the tension spring causes the locking rod 62 to move downwards, thus unlocking the carriage 3.
[0038] The working principle and usage process of this utility model are as follows: During use, the operator pushes the utility model to the designated position using handle 4 to receive sludge. When the truck bed 3 is full of sludge and unloading is required, the operator pushes the sludge receiving cart to the sludge dumping area. After reaching the designated position, the operator uses the foot brake to fix the caster wheel 11. Then, by manually lifting and rotating the locking rod 62, the locking rod 62, with the help of the spring 67, can disengage from the recesses of the first recessed block 63 and the second recessed block 64, causing both the support plate 2 and the truck bed 3 to be in the unlocked state. Workers push the carriage 3 forward using handle 4, causing the carriage 3 and support plate 2 to slide stably through the cooperation of slider 8 and guide rail 7. When slider 8 contacts the stop block 9 on one side, workers lift the carriage 3 using handle 4, ensuring that the carriage 3 rotates at the connection point with support plate 2, thus tilting it over and completing the dumping of sludge, which improves the efficiency of sludge dumping to a certain extent. During this process, baffle 12 can rotate under gravity and be perpendicular to the front face of the carriage 3, allowing baffle 12 to adhere to the inner wall of the dumping port and prevent the carriage 3 from shaking. It is worth noting that if a small amount of sludge remains in the carriage 3 after dumping, or if some sludge adheres, workers can use external tools (such as shovels) to remove it, reducing the amount of sludge residue in the carriage 3.
