Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and specifically relates to a skimming cart for a reciprocating oil and slag scraper. Background Technology

[0002] Currently, the scum produced by horizontal flow aerated grit chambers is generally treated by independent rotary chain plate skimmers or reciprocating flip-plate skimmers integrated with gantry sand suction machines. These types of equipment are relatively mature and widely used, each with its own advantages and disadvantages in production and use.

[0003] Rotary chain-plate skimmers, considering corrosion resistance and weight, generally use a non-metallic chain to drive skimming plates to scrape scum to a scum cylinder at one end, such as the skimming and sludge scraper disclosed in Chinese Patent CN102527105A. This equipment is simple to operate, has good skimming effect, and high efficiency, but its disadvantages are high cost, easy wear, and difficult maintenance. Integrated scraping and suction equipment, such as the skimming device of the bridge-type sand suction machine disclosed in Chinese Patent CN102784497B, has low cost, simple operation, and low maintenance, but its disadvantage is that due to the influence of the sand suction bridge, the stroke cannot reach both ends, resulting in low skimming efficiency.

[0004] To address the aforementioned issues, the applicant developed a reciprocating mobile oil and slag skimmer, which primarily employs a drive structure to move the skimmer back and forth between a first position and a second position, thereby scraping the oil slag to the discharge pipe at the first position for discharge. The skimmer needs to ensure that the scraper assembly is in place before it begins to move, thus guaranteeing the skimming efficiency. Utility Model Content

[0035] The above solution will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrating the present invention and are not intended to limit the scope of the present invention. The implementation conditions used in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0036] See Figure 1The diagram below is a structural schematic of an embodiment of the present invention. It provides a skimming vehicle for a reciprocating oil and slag scraper, including a frame 101, a drive slide rod 104 slidably disposed on the frame 101, a scraper assembly rotatably disposed on the frame 101, and a stop block assembly fixed on the frame 101, wherein the scraper assembly is throttlely connected to the drive slide rod 104.

[0037] To facilitate the movement of the slag skimmer 100, a front wheel assembly 102 and a rear wheel assembly 103 are provided on the frame 101. The front wheel assembly 102 includes two front wheels located on both sides of the frame 101 in the direction of movement, and the rear wheel assembly 103 includes two rear wheels located on both sides of the frame 101 in the direction of movement.

[0038] The drive slide rod 104 is slidably engaged with the upper end surface of the frame 101 and connected to the traction component 300. The drive slide rod 104 slides back and forth along the frame 101 under the drive of the traction component 300. In this example, the traction component 300 is a steel wire rope. The traction component 300 is sleeved on the drive wheel 400 and the driven wheel 500. The drive wheel 400 is connected to the geared motor 600. The geared motor 600 drives the drive wheel 400 to rotate, thereby driving the driven wheel 500 to rotate synchronously, thereby driving the steel wire rope to move back and forth, and then driving the drive slide rod 104 to slide along the frame 101. The transmission structure between the drive wheel 400 and the geared motor 600 adopts the prior art, which will not be described in detail in this utility model.

[0039] To facilitate the connection between the drive slide 104 and the traction component 300, limiting holes 104b are provided at both ends of the drive slide 104 for the traction component 300 to pass through. The traction component 300 is fixedly connected to the drive slide 104 via multiple bolt and nut assemblies 115.

[0040] In order to prevent the drive slide 104 from sliding and causing wear to the frame 101, a wear-resistant plate 113 is provided between the drive slide 104 and the upper end face of the frame 101. The wear-resistant plate 113 can be made of wear-resistant steel plate in the prior art.

[0041] When the drive slide rod 104 slides on the frame 101, in order to ensure that the movement direction of the drive slide rod 104 is consistent with that of the traction component 300, a guide assembly for guiding the drive slide rod 104 is provided at the upper end of the frame 101. Specifically, the guide assembly includes multiple guide wheels 114 arranged on both sides of the drive slide rod 104, and a support shaft arranged vertically on the frame 101. The guide wheels 114 are rotatably engaged with the support shaft. When the drive slide rod 104 moves, the guide wheels 114 on both sides can ensure that the drive slide rod 104 slides in the movement direction of the traction component 300, thereby improving the working efficiency of the skimming vehicle 100.

[0042] The stop assembly is used to limit the forward or backward position of the drive slide bar 104, including a first stop bar 109 and a second stop bar 110, to limit the forward and backward movement of the drive slide bar 104. When the drive slide bar 104 abuts against the first stop bar 109, the scraper assembly falls down, and then the drive slide bar 104 drives the frame 101 forward. When the drive slide bar 104 abuts against the second stop bar 110, the scraper assembly is lifted up, and then the drive slide bar 104 drives the frame 101 backward.

[0043] To facilitate the engagement of the drive slide bar 104 with the stop assembly, the drive slide bar 104 is provided with a downwardly extending limiting portion 104a. The limiting portion 104a abuts against the stop assembly to limit the forward and backward movement and drive the frame 101. Specifically, the frame 101 is provided with a through groove running vertically through it. The limiting portion 104a extends below the through groove, and the stop assembly is fixed to the side wall of the through groove and located on both sides of the limiting portion 104a.

[0044] The scraper assembly includes a first scraper 105 rotatably disposed at the front end of the frame 101 and a second scraper 106 rotatably disposed at the rear end of the frame 101. By setting the front and rear scraper plates, it can be ensured that the skimming vehicle 100 scrapes off the oil sludge on the water surface during the movement.

[0045] Specifically, a first mounting seat 116 is provided at the front end of the frame 101, and a second mounting seat 117 is provided at the rear end of the frame 101. A first scraper 105 is rotatably supported on the first mounting seat 116 via a first support 111, and a second scraper 106 is rotatably supported on the second mounting seat 117 via a second support 112. The first support 111 is rod-shaped and rotatably connected to the first mounting seat 116, the first scraper 105 is fixedly connected to the first support 111, the second support 112 has a fan-shaped plate structure and is rotatably connected to the second mounting seat 117, and the second scraper 106 is fixedly connected to the second support 112.

[0046] To facilitate the transmission connection between the scraper assembly and the drive slide 101, a connecting rod assembly is also included to connect the scraper assembly and the drive slide 104. Specifically, the connecting rod assembly includes a first connecting rod 107 with one end hinged to the first support 111 and the other end hinged to the limiting part 104a, and a second connecting rod 108 with one end hinged to the second support 112 and the other end hinged to the limiting part 104a. When the drive slide 104 moves back and forth, the connecting rod assembly drives the scraper assembly to rotate, thereby realizing the scraper assembly falling or rising.

[0047] The working principle of this utility model is as follows:

[0048] like Figure 2As shown, the front wheel assembly 102 and the rear wheel assembly 103 of the skimming vehicle 100 are rolled on two guide rails 201 on opposite sides of the pool body 200, and move back and forth between the first position and the second position under the drive of the traction component 300, so as to scrape the oil sludge on the water surface to the sludge discharge pipe 202 of the first position for discharge.

[0049] When the skimmer 100 is in the second position, the drive slide 104 abuts against the second stop 109. At this time, the first scraper 105 and the second scraper 106 are raised, and the skimmer 100 enters the forward stroke. The reduction motor 600 is turned on, causing the traction component 300 to drive the skimmer 100 to move towards the first position. Since the skimmer 100 is restricted by the second limiter at the second position, the drive slide 104 slides along the frame 101 and drives the first scraper 105 and the second scraper 106 to rotate. When the drive slide 104 abuts against the first stop 109, the first scraper 105 and the second scraper 106 fall down. After that, the drive slide 104 drives the skimmer 100 to move forward. The rear wheel assembly 103 disengages from the second limiter, and the skimmer 100 moves forward until it reaches the first position. After the position switch sends a signal, the reduction motor 600 is turned off, causing the traction component 300 to stop running. At this time, the front wheel assembly 102 is temporarily positioned by the first limiter at the first position.

[0050] Then, the skimmer 100 enters its reverse stroke, and the reduction motor 600 is activated, causing the traction component 300 to move the skimmer 100 towards the second position. Since the skimmer 100 is restricted by the first limiter, the drive slide rod 104 slides along the frame 101 and drives the first scraper 105 and the second scraper 106 to rotate. When the drive slide rod 104 abuts against the second stop 110, the first scraper 105 and the second scraper 106 are lifted. After that, the drive slide rod 104 drives the skimmer 100 to move backward, the front wheel assembly 102 disengages from the first limiter, and the skimmer 100 moves backward until it reaches the second position. After the position switch sends a signal, the reduction motor 600 is turned off, causing the traction component 300 to stop running. The rear wheel assembly 103 is temporarily positioned by the second limiter. This process is repeated until the skimming is completed.

[0051] In summary, this slag skimmer has a simple structure, is easy to operate and maintain, and has high slag skimming efficiency.

[0052] The above examples are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
