Description

Technical Field

[0001] The utility model relates to the technical field of mud feeding, in particular to a feeding device for a mud pulping machine. Background Art

[0002] With the development of engineering construction technology, mud plays an important role in drilling work. The mud used for drilling can clean the rock cuttings carried by the bottom of the well. The mud also has the function of balancing the side pressure of the well wall rock and forming a mud cake on the well wall to keep the well wall stable and prevent the well wall from collapsing. In the production of mud, sticky mud, also known as clay, is prepared. In the existing technology, a mud machine is used to directly stir and flush the clay to make mud.

[0003] During the production process, a mud machine is used to make slurry from the sludge. A conveyor belt is used to load the material at the feed point of the mud machine. In order to facilitate the feeding of the sludge, a baffle is installed at the inlet of the mud machine to prevent the sludge from splashing. However, due to the certain viscosity of the sludge, a large amount of sludge will adhere to the baffle, resulting in errors in the feed weight and affecting the slurrying quality. Therefore, this technical solution is proposed for improvement. Utility Model Content

[0015] The preferred embodiments of the utility model are described below with reference to the drawings, and those skilled in the art should understand that these embodiments are only used to explain the technical principles of the utility model and are not intended to limit the protection scope of the utility model.

[0016] Referring to Figs. 1-2 The embodiment of the utility model discloses a mud pulper feeding device, which mainly comprises a conveying belt 1, a feeding bin 5 arranged at the inlet of a mud pulper body 2, a baffle 3, a driving device 301 and a scraping device, etc.

[0017] The conveying belt 1 is preferably a weighing type conveying machine, which can measure the weight of the sticky mud in real time during conveying, ensures that the amount of sticky mud sent into the mud machine is accurately controllable, provides accurate raw material amount for the pulping process, and the inner side of the feeding bin 5 opposite to the conveying belt 1 is provided with a baffle 3, which is used to prevent mud splashing and keep the working environment clean. The bottom of the baffle 3 is connected to the shell of the mud machine body 2 by hinging, so that it can move within a certain range. The driving device 301 is used to push the baffle 3 to swing or adjust the position when needed, so as to better cooperate with the scraping device to work. The driving device 301 can be selected from one of an electric push rod, an air cylinder or an oil cylinder, and the specific selection can be determined according to actual needs and site conditions. In the use process, the driving device 301 pushes the baffle 3 to tilt to one side of the conveying belt 1, adjusts the feeding angle of the sticky mud, and improves the feeding effect.

[0018] A scraping device is arranged on the working surface of the baffle 3, which mainly includes a scraper 4. The scraper 4 is installed on the inner wall of the feeding bin 5 and is arranged at an angle with the baffle 3. The top of the scraper 4 abuts against the working surface of the baffle 3. A connecting seat 402 is hingedly arranged at the bottom of the scraper 4. The connecting seat 402 is slidingly connected with a sliding groove 501 on the inner wall of the feeding bin 5, so as to ensure that the scraper 4 can move smoothly along the sliding groove 501. The side edge of the scraper 4 is connected with a metal spring 403 arranged on the upper part of the feeding bin 5 through a spring, which provides a restoring force for the scraper 4 and makes it tightly fit the surface of the baffle 3. A gas spring 502 is further arranged on the side of the connecting seat 402 close to the baffle 3. The other end of the gas spring 502 is fixedly arranged in the sliding groove 501, so that the connecting seat 402 slides to the left under the action of the baffle 3, adjusts the relative position during scraping, generates a certain resistance, improves the scraping effect, avoids damage caused by rigid contact, and also enhances the self-adaptive ability of the scraper 4. The top of the scraper 4 is designed as an inclined surface abutting against the baffle 3, which is convenient for the introduction and scraping of sticky mud. An arc-shaped plate 401 is arranged on the bottom surface of the scraper 4 and faces the baffle 3. During the use of the mud machine body 2, part of the materials splashed during the conveying of the conveying belt 1 will directly adhere to the baffle 3. According to the use requirements, the driving device 301 is started at regular intervals to deflect the baffle 3 to one side of the conveying belt 1. During the rotation, the top of the scraper 4 will slide downward along the baffle 3 due to the abutment between the top surface of the scraper 4 and the baffle 3, and then the sticky mud adhering to the baffle 3 is scraped off. Since the sticky mud has a certain viscosity, it will move along the lower surface of the scraper 4 during scraping. The arc-shaped plate 401 blocks the sticky mud, so as to make the sticky mud fall off and reduce the amount of sticky mud adhering to the baffle 3, thereby ensuring the cleaning effect. During the rotation of the baffle 3, the gas spring 502 moves the connecting seat 402 to the left, so that the scraper 4 always has a certain force, thereby ensuring the cleaning effect. After the cleaning is completed, the baffle 3 is reset, and the scraper 4 is reset under the action of the metal spring 403 and the gas spring 502, thereby realizing reciprocating cleaning and greatly improving the cleaning effect, ensuring the weight accuracy of the batch amount, and improving the pulping quality.

[0019] Working principle: with the continuous accumulation of sticky mud, part of the sticky mud will adhere to the baffle 3, the driving device 301 is started, the baffle 3 is pushed to swing or adjust position in a small range, and the scraper 4 in the scraping device moves closely to the surface of the baffle 3 under the action of the spring and the gas spring 502, so that the adhered sticky mud is scraped off and falls into the feeding bin 5 to continue to participate in the pulping process, effectively solving the problem of weight error caused by the adhesion of sticky mud on the baffle 3, and improving the pulping quality and efficiency.
