Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment tank alum throwing device for wastewater treatment. Background Technology

[0002] Wastewater treatment refers to the purification of polluted industrial wastewater or river water through a series of water treatment equipment to meet the national water quality standards. In wastewater treatment ponds, alum, as a commonly used wastewater treatment agent, plays an important role. In order to place alum in the water, an alum throwing device is required.

[0003] A wastewater treatment tank alum throwing device with application number CN201922290072.5 includes a workbench, a first settling tank on the top surface of the workbench, a first annular groove on the inner circumference of the first settling tank, a rotating column inside the first settling tank, and a ring fitted on the outer circumference of the rotating column. The ring is rotatably connected to the first annular groove. A connecting plate is symmetrically provided on the top surface of the rotating column. This wastewater treatment tank alum throwing device can throw alum to different positions through the cooperation of a set ejection mechanism and a pulling mechanism, without the need for manual force. The operation process is very time-saving and labor-saving. Moreover, the loading pipe can be adjusted in height and rotation, so that the alum can be thrown to different positions with a wide throwing range. This solves the problem that the throwing range of alum in water is small and that workers still need to throw alum with force, making the operation time-consuming and labor-intensive.

[0004] The device purifies wastewater by launching alum into the sewage tank. However, the device cannot quickly fill the alum inside the launching mechanism, requiring manual filling, which affects the efficiency of alum launching.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing structure of alum-pouring equipment for wastewater treatment ponds. Utility Model Content

[0006] The purpose of this utility model is to provide a wastewater treatment tank alum throwing device for wastewater treatment, so as to solve the problem mentioned in the background art that the device cannot quickly fill the alum inside the ejection device during throwing, and manual filling is required, which affects the efficiency of alum throwing.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment tank alum throwing device for wastewater treatment, comprising a support frame, wherein a rotating shaft is rotatably connected to the inner side of the support frame; a swing platform, wherein the swing platform is fixedly connected to the top of the rotating shaft and is tilted at 15° when viewed from the front; further comprising: a catapult track, wherein the catapult track is fixedly connected to the upper end of the swing platform; a handle, wherein the handle is fixedly connected to the tail of the swing platform; a catapult assembly, wherein the catapult assembly is disposed inside the catapult track; and a feeding assembly, wherein the feeding assembly is disposed outside the catapult track and is connected to the catapult assembly; wherein the catapult assembly is used to catapult granular alum; and the feeding assembly is used to intermittently feed the catapult track.

[0008] Preferably, the ejection assembly includes a fixed sleeve, a telescopic spring, and an ejection block. The fixed sleeve is fixedly connected to the outside of the ejection track, and the fixed sleeve is connected to the ejection block through the telescopic spring. The ejection block is slidably connected to the inside of the ejection track.

[0009] Preferably, the ejection assembly further includes a rack, which is fixedly connected to the outside of the ejection block.

[0010] Preferably, the ejection assembly further includes a servo motor and a gear. The servo motor is fixedly connected to the bottom of the swing platform, and the output end of the servo motor passes through the inner side of the swing platform. The output end of the servo motor is fixedly connected to a gear, and the gear meshes with an outer rack.

[0011] Preferably, the gear is viewed from above as a half-tooth structure.

[0012] Preferably, the feeding assembly includes a feeding box and a discharging pipe. The feeding box is fixedly connected to the upper end of the swing platform, and the discharging pipe is fixedly connected to the outside of the feeding box.

[0013] Preferably, the feeding assembly further includes a notch, a docking pipe, a guide block, and a sliding track. The notch is opened inside the ejection track, and a docking pipe is provided inside the notch. A guide block is fixedly connected to the bottom of the docking pipe, and the guide block is slidably connected to the inside of the sliding track. The sliding track is fixedly installed on the upper end of the swing platform.

[0014] Preferably, the feeding assembly further includes a first connecting rod and a second connecting rod, wherein the first connecting rod is rotatably connected to the outside of the gear, and the end of the first connecting rod is rotatably connected to the second connecting rod, and the tail end of the second connecting rod is fixedly connected to the outside of the docking pipe.

[0015] Compared with the prior art, the beneficial effect of this utility model is that the alum dosing device for sewage treatment ponds is equipped with:

[0016] 1. Ejection structure: When granular alum needs to be thrown into the sewage tank, the servo motor is first activated, which drives the gear to rotate. When the gear teeth mesh with the rack, the gear drives the ejector block connected to the rack to move to the rear end of the ejection track, and stretches the telescopic spring between the fixed sleeve and the ejector block. When the outer teeth of the gear separate from the rack, the ejector block is reset by the elastic force of the telescopic spring, so that the ejector block moves forward along the inner side of the ejection track, ejecting the granular alum inside the ejection track and throwing it into the designated position in the sewage tank to purify the sewage.

[0017] Furthermore, the swing platform is rotatably connected to the upper end of the support frame via a rotating shaft. Users can hold the handle to adjust the throwing angle of the swing platform, thereby ensuring that the granular alum is evenly sprinkled into the sewage tank.

[0018] 2. Intermittent feeding structure: When the gear rotates, it drives the first connecting rod on the outside to swing left and right. The swing of the first connecting rod pushes and pulls the second connecting rod at the end, causing the docking pipe to move back and forth along the inside of the notch. When the docking pipe is at the front end of the notch, it connects with the discharge pipe, allowing the granulated alum inside the feeding box to enter the inner side of the ejection track for filling through the constructed pipeline. When the docking pipe is at the rear end of the notch, the discharge pipe and the docking pipe are misaligned, and the feeding box stops feeding the ejection track. Through the reciprocating rotation of the gear, the feeding box reciprocates to feed the ejection track, improving the efficiency of alum granule throwing. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 This utility model provides a technical solution: a wastewater treatment tank alum throwing device for wastewater treatment, comprising:

[0027] Example 1: As Figures 1-5 The present invention provides a technical solution: a wastewater treatment tank alum throwing device for wastewater treatment, comprising: a support frame 1, with a rotating shaft 2 rotatably connected to the inner side of the support frame 1; a swing platform 3, fixedly connected to the top of the rotating shaft 2, and the swing platform 3 is tilted at 15° when viewed from the front; further comprising: a catapult track 4, fixedly connected to the upper end of the swing platform 3; a handle 7, fixedly connected to the tail of the swing platform 3; a catapult assembly 5, disposed inside the catapult track 4; and a feeding assembly 6, disposed outside the catapult track 4 and connected to the catapult assembly 5; wherein, the catapult assembly 5 is used to catapult granular alum; and the feeding assembly 6 is used to intermittently feed the catapult track 4;

[0028] The ejection assembly 5 includes a fixed sleeve 501, a telescopic spring 502, and an ejection block 503. The fixed sleeve 501 is fixedly connected to the outside of the ejection track 4, and the fixed sleeve 501 is connected to the ejection block 503 through the telescopic spring 502. The ejection block 503 is slidably connected to the inside of the ejection track 4. The ejection assembly 5 also includes a rack 504, which is fixedly connected to the outside of the ejection block 503. The ejection assembly 5 also includes a servo motor 505 and a gear 506. The servo motor 505 is fixedly connected to the bottom of the swing platform 3, and the output end of the servo motor 505 passes through the inside of the swing platform 3. The output end of the servo motor 505 is fixedly connected to the gear 506, and the gear 506 meshes with the outer rack 504. The gear 506 is viewed from above as a half-tooth structure.

[0029] When this structure needs to throw granular alum into the sewage tank, the servo motor 505 is first activated, which drives the gear 506 to rotate. When the tooth surface of the gear 506 meshes with the rack 504, the gear 506 drives the ejector block 503 connected to the rack 504 to move towards the rear end of the ejector track 4, and stretches the telescopic spring 502 between the fixed sleeve 501 and the ejector block 503. When the outer tooth surface of the gear 506 separates from the rack 504, the ejector block 503 is reset by the elastic force of the telescopic spring 502, so that the ejector block 503 moves forward along the inner side of the ejector track 4, ejecting the granular alum inside the ejector track 4 and throwing it into the designated position in the sewage tank to purify the sewage. The swing platform 3 is rotatably connected to the upper end of the support frame 1 through the rotating shaft 2. The user can hold the handle 7 to adjust the throwing angle of the swing platform 3, so that the granular alum is evenly sprinkled into the sewage tank.

[0030] Example 2: Figures 1-5 The present invention provides a technical solution: a wastewater treatment tank alum throwing device for wastewater treatment, which discloses that: the feeding component 6 includes a feeding box 601 and a discharge pipe 602. The feeding box 601 is fixedly connected to the upper end of the swing platform 3, and the discharge pipe 602 is fixedly connected to the outside of the feeding box 601; the feeding component 6 also includes a notch 603, a docking pipe 604, a guide block 605, and a sliding track 606. The notch 603 is opened inside the ejection track 4, and the inside of the notch 603 is provided with... The docking pipe 604 has a guide block 605 fixedly connected to its bottom, and the guide block 605 is slidably connected to the inner side of the sliding rail 606, and the sliding rail 606 is fixedly installed on the upper end of the swing platform 3; the feeding assembly 6 also includes a first connecting rod 607 and a second connecting rod 608, the first connecting rod 607 is rotatably connected to the outside of the gear 506, and the end of the first connecting rod 607 is rotatably connected to the second connecting rod 608, and the tail end of the second connecting rod 608 is fixedly connected to the outside of the docking pipe 604;

[0031] When gear 506 rotates, this structure causes the outer first connecting rod 607 to swing left and right. The swinging of the first connecting rod 607 pushes and pulls the second connecting rod 608 connected to the end, causing the docking pipe 604 to move back and forth along the inside of the notch 603. When the docking pipe 604 is at the front end of the notch 603, it will be connected to the discharge pipe 602, so that the granular alum inside the feeding box 601 enters the inner side of the catapult track 4 through the constructed pipeline for filling. When the docking pipe 604 is at the rear end of the notch 603, the discharge pipe 602 and the docking pipe 604 are in a misaligned state, and the feeding box 601 stops feeding the catapult track 4. Through the reciprocating rotation of gear 506, the feeding box 601 reciprocates to feed the catapult track 4, improving the efficiency of alum granule throwing.
