Description

Technical Field

[0001] The present application relates to the technical field of filtering devices, and particularly to a filter device for accelerating agents. Background Art

[0002] After the liquid accelerating agent is stored for a long time, crystals will be generated inside. When using the liquid accelerating agent to mix with concrete, in order to avoid affecting the use of the liquid accelerating agent, a filtering device is needed to filter out the crystals inside the liquid accelerating agent.

[0003] The existing filtering of accelerating agents mainly uses centrifugal filtration. The accelerating agent is loaded into a centrifugal cylinder, and the centrifugal cylinder is rotated to separate the liquid accelerating agent and the solid crystals under the action of centrifugal force. At the same time, the crystals can throw off the accelerating agent carried on themselves under the action of centrifugal force, improving the filtering effect.

[0004] In the above solution, the filtered crystals are usually discharged through a waste discharge pipe connected to the bottom end of the centrifugal cylinder. Since the area of the waste discharge pipe is smaller than the area of the bottom end of the centrifugal cylinder, it is easy to cause some crystals to remain in the centrifugal cylinder, reducing the effect of crystal cleaning. Utility Model Content

[0005] In order to improve the cleaning effect of crystals, the present application provides a filter device for accelerating agents.

[0006] A filter device for accelerating agents provided by the present application adopts the following technical solution:

[0007] A filter device for accelerating agents includes a filter box, a filter mesh cylinder, a cleaning plate, and a cylinder. The filter mesh cylinder rotates and penetrates through the filter box, and the cleaning plate is slidably arranged in the filter mesh cylinder along the rotation axis direction of the filter mesh cylinder. The cleaning plate and the filter mesh cylinder form a centrifugal filtration space, the filter mesh cylinder and the filter box form a filtrate storage space, the cylinder is fixedly connected to the filter box, and the movable end of the cylinder is connected to the cleaning plate. The telescopic direction of the cylinder is the same as the sliding direction of the cleaning plate.

[0008] By adopting the above technical solution, during centrifugal filtration, the accelerating agent is loaded into the centrifugal filtration space, the centrifugal mesh cylinder is rotated, and the centrifugal mesh cylinder drives the cleaning plate and the accelerating agent to rotate. The filtration of the accelerating agent and the crystals is realized through centrifugal force, and the filtered accelerating agent enters the filtrate storage space; when cleaning the crystals, the cleaning plate is driven to slide by the cylinder, and the cleaning plate scrapes and pushes the crystals in the centrifugal filtration space during the sliding process, so that the crystals can be completely discharged from the filter mesh cylinder, improving the cleaning effect of the crystals.

[0009] Optionally, a circular plate-shaped connecting plate is fixedly connected to the movable end of the cylinder. A circular connecting groove is formed on one side of the cleaning plate close to the cylinder. The axis of the connecting groove coincides with the rotation axis of the filter mesh cylinder. The connecting plate is rotatably arranged in the connecting groove, and the notch of the connecting groove extends towards the direction close to its own center.

[0010] By adopting the above technical solution, through the rotational connection between the connecting plate and the connecting groove, the movable end of the cylinder is rotatably connected to the cleaning plate. By applying a clamping effect on the connecting plate through the extending part of the notch of the connecting groove, the cylinder can drive the cleaning plate to reciprocate, so that the cylinder is not easily interfered with the rotation of the cleaning plate along with the filter mesh cylinder under the condition of reciprocally driving the cleaning plate to slide.

[0011] Optionally, the side of the cleaning plate away from the cylinder protrudes outward in a conical shape towards the direction away from the cylinder. A circular ring-shaped storage groove is arranged on the side of the filter box away from the cylinder. The central axis of the storage groove coincides with the rotation axis of the filter mesh cylinder.

[0012] By adopting the above technical solution, when the cleaning plate pushes the crystals out of the filter mesh cylinder, the conical surface of the cleaning plate can guide the crystals to slide into the storage groove, making it convenient to centrally collect and store the crystals.

[0013] Optionally, the storage groove is circular ring-shaped, and a sealing cover is adaptively covered at the notch position. The outer side wall of the sealing cover is threadedly connected to the inner side wall of the outer wall of the storage groove.

[0014] By adopting the above technical solution, the sealing cover is threadedly connected to the notch position of the storage groove. On the one hand, the sealing cover enables the crystals in the storage groove to be stably stored in the storage groove during centrifugal filtration. On the other hand, the sealing cover makes the quick-setting agent in the filter mesh cylinder not easily splash out of the filter mesh cylinder during centrifugal filtration.

[0015] Optionally, the filter mesh cylinder is circular cylindrical. A cleaning rod brush is connected to one side of the sealing cover close to the filter mesh cylinder. The cleaning rod brush is parallel to the axis direction of the filter mesh cylinder and abuts against the inner side wall of the filter mesh cylinder.

[0016] By adopting the above technical solution, during centrifugal filtration, the cleaning rod brush can move relative to the filter mesh cylinder. The cleaning rod brush can clean the crystals attached to the inner wall of the filter mesh cylinder. On the one hand, the cleaning rod brush makes it not easy for the crystals to block the filter mesh cylinder during centrifugal filtration. On the other hand, the cleaning rod brush makes the crystals easy to fall on the cleaning plate, further improving the cleaning effect of the cleaning plate on the crystals.

[0017] Optionally, a connecting pipe is fixedly connected to the sealing cover. The connecting pipe is located at the connection position between the sealing cover and the cleaning rod brush. The end of the cleaning rod brush is inserted into the connecting pipe and is threadedly connected to the connecting pipe.

[0018] By adopting the above technical solution, the cleaning rod brush is threadedly connected to the sealing cover through the connecting pipe, so that the cleaning rod brush can be easily detached from the sealing cover, and thus the cleaning rod brush can be easily replaced.

[0019] Optionally, a motor is fixedly provided on one side of the filter box close to the cylinder. The output shaft of the motor rotates through the bottom end of the filter box. A gear is coaxially fixed to the output shaft of the motor, and a gear ring is externally engaged with the gear. The gear ring is coaxially fixedly sleeved on the filter mesh cylinder.

[0020] By adopting the above technical solution, the motor can drive the filter mesh cylinder to rotate through the gear and the gear ring, so that the filter mesh cylinder can filter the quick-setting agent by means of centrifugal force.

[0021] Optionally, a liquid inlet pipe is communicated with the sealing cover, and a liquid outlet pipe is communicated with the filter box.

[0022] By adopting the above technical solution, the quick-setting agent can be added through the liquid inlet pipe when the storage tank and the filter mesh cylinder are sealed by the sealing cover, and the filtered quick-setting agent can be discharged from the filter box through the liquid outlet pipe, so that the quick-setting agent can be continuously centrifugally filtered.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By providing the filter box, the filter mesh cylinder, the cleaning plate and the cylinder, the cylinder can drive the cleaning plate to push all the crystals out of the filter mesh cylinder, improving the cleaning effect of the crystals;

[0025] 2. By making the side of the cleaning plate away from the cylinder protrude in a conical shape and providing a storage tank on the filter box, the crystals are conveniently collected and stored centrally;

[0026] 3. By providing the cleaning rod brush on the sealing cover, the crystals are not easily blocked in the filter mesh cylinder and are easily dropped onto the cleaning plate. BRIEF DESCRIPTION OF THE DRAWINGS

The filter mesh cylinder 2 drives the cleaning plate 3 and the quick-setting agent to rotate, so that the crystallization is filtered in the centrifugal filtration space; when it is necessary to clean the crystallization, stop the motor 7 and start the air cylinder 4. The air cylinder 4 drives the cleaning plate 3 to slide. During the sliding process of the cleaning plate 3, the crystallization attached to the side wall of the filter mesh cylinder 2 is scraped off, and the crystallization in the centrifugal filtration space is pushed out of the filter mesh cylinder 2, improving the cleaning effect of the crystallization.
