[0001] The utility model belongs to the technical field of slurry inlet quantity metering, and more specifically, particularly relates to a slurry inlet quantity metering device for a drilling mud filter press. Background Art
[0002] Drilling mud filter presses usually use plate and frame filter presses, which are the first machines used in chemical dehydration. Although plate and frame filter presses are generally intermittently operated, with large infrastructure equipment investment and low filtration capacity, they are widely used due to their advantages such as large filtration driving force, high solid content of filter cake, clear filtrate, high solid recovery rate, and low consumption of conditioning drugs. During the use of plate filter presses, slurry is usually supplied to the plate filter presses through mud tanks.
[0003] The current mud tank metering device still has the following shortcomings:
[0004] The current mud tank metering device usually adopts pipeline flow meter. During the use of pipeline flow meter, it is often easy to get blocked, resulting in untimely and inaccurate calculation of mud volume, which cannot guarantee the normal operation of the equipment, is not convenient to use, has low reliability and has great limitations.

[0006] The purpose and function of the slurry inlet metering device of the utility model for a drilling mud filter press are achieved by the following specific technical means:
[0007] A drilling mud filter press slurry inlet metering device comprises: a bracket; the bracket adopts a circular ring structure; a tank body is fixedly arranged on the inner side of the top of the bracket; a slide rail is fixedly arranged on the front side of the tank body, and scale values are arranged on both sides of the front wall of the slide rail; a pointer is slidably arranged on the inner side of the slide rail.
[0008] Furthermore, a motor is fixedly arranged at the bottom of the tank body; a stirring roller is rotatably arranged inside the tank body, and the stirring roller is transmission-connected to the motor; a mounting frame is fixedly arranged at the top front side of the tank body, and the mounting frame adopts a U-shaped plate structure.
[0009] Furthermore, a group of rollers are rotatably arranged on the upper and lower sides of the interior of the mounting frame; a controller is fixedly arranged on the front side of the bracket, and the controller model is a PLC controller, and the controller and the pointer are electrically connected through a data line; a cylindrical counterweight block is fixedly arranged on the bottom of the pointer; two groups of limit plates with arc-shaped plate structures are fixedly arranged on the front side of the interior of the tank body, and the two groups of limit plates are symmetrically arranged on the left and right.
[0010] Furthermore, a float is slidably arranged between the two groups of limit plates. The float adopts a spherical structure, and the diameter of the float matches the diameter between the two groups of limit plates. The weight of the float is the same as the weight of the counterweight. The float and the pointer are fixedly connected by a steel wire rope, and the steel wire rope between the float and the pointer passes around the two groups of rollers; a group of scrapers with a circular plate structure are fixedly arranged on the upper and lower sides of the float, and the outer wall of the scraper is in contact with the inner wall of the two groups of limit plates.

[0022] Embodiment 1:
[0023] As attached Figure 1 To Attachment Figure 5 As shown:
[0024] The utility model provides a drilling mud filter press slurry inlet metering device, comprising: a bracket 1; the bracket 1 adopts a circular ring structure; a tank body 101 is fixedly arranged on the inner side of the top of the bracket 1; a slide rail 107 is fixedly arranged on the front side of the tank body 101, and scale values are arranged on both sides of the front wall of the slide rail 107; a pointer 108 is slidably arranged on the inner side of the slide rail 107.
[0025] Among them, a motor 102 is fixedly installed at the bottom of the tank body 101; a stirring roller 103 is rotatably installed inside the tank body 101, and the stirring roller 103 is transmission-connected to the motor 102; a mounting frame 104 is fixedly installed on the top front side of the tank body 101, and the mounting frame 104 adopts a U-shaped plate structure.
[0026] Among them, a group of rollers 105 are rotatably arranged on the upper and lower sides of the interior of the mounting frame 104; a controller 106 is fixedly arranged on the front side of the bracket 1, and the model of the controller 106 is a PLC controller, and the controller 106 is electrically connected to the pointer 108 through a data line; a cylindrical counterweight block 109 is fixedly arranged at the bottom of the pointer 108; two groups of limit plates 110 with arc-shaped plate structures are fixedly arranged on the front side of the interior of the tank body 101, and the two groups of limit plates 110 are symmetrically arranged on the left and right.
[0027] The specific usage and function of this embodiment are as follows:
[0028] When in use, the float 111 and the scraper 112 are placed between the two groups of limit plates 110, so that the float 111 can only slide up and down between the two groups of limit plates 110, and then after the mud is added to the inner side of the tank body 101, the motor 102 is started to drive the stirring roller 103 to rotate and stir the mud, so that the liquid surface of the mud can be kept flat, and the mud will not be completely flattened in the tank body 101 due to the relatively viscous mud, which will affect the accuracy of the liquid level detection. After the mud enters the tank body 101, it will flow between the two groups of limit plates 110, so that the float 111 generates buoyancy, so that the float 111 It can slide upward between the two sets of limit plates 110. At the same time, after the float 111 slides upward, the wire rope becomes loose and loses the limit state for the pointer 108. The pointer 108 slides downward along the slide rail 107 under the action of the counterweight 109. The liquid level in the tank body 101 can be directly known by observing the scale values on the pointer 108 and the slide rail 107, and the controller 106 is programmed to convert it into the actual slurry intake and display it on the control panel, so that the slurry amount in the tank body 101 can be effectively and accurately monitored. Compared with traditional pipeline flow meters, this device is more durable, will not be blocked, and is more convenient to use.

[0032] The specific usage and function of this embodiment are as follows:
[0033] In the utility model, when the mud level in the tank body 101 drops, the float 111 and the scraper 112 slide downward, so that the mud adhered to the inner walls of the two groups of limit plates 110 can be scraped and cleaned through the bottom group of scrapers 112, thereby keeping the inner walls of the two groups of limit plates 110 clean and tidy, ensuring the smoothness of the float 111 sliding up and down, and also reducing the cleaning burden of the staff.
