Description

Technical Field

[0001] The utility model relates to the technical field of bentonite modification, in particular to bentonite alkali adding equipment. Background Art

[0002] Bentonite is also called bentonite, soap clay or bentonite rock. Bentonite is a non-metallic mineral with montmorillonite as the main mineral component. The montmorillonite structure is a 2:1 type crystal structure composed of two silicon-oxygen tetrahedrons sandwiching a layer of aluminum-oxygen octahedron. Due to the layered structure formed by the montmorillonite unit cell, there are certain cations, such as Cu, Mg, Na, K, etc., and these cations are very unstable in the reaction with the montmorillonite unit cell and are easily exchanged by other cations, so it has good ion exchangeability. In order to change the properties of bentonite and improve its performance indicators, it is necessary to add soda ash to it for alkali addition.

[0003] After searching, it was found that the alkali-adding equipment in the prior art does not have a crushing component, and soda ash easily absorbs moisture and agglomerates. The lumps of soda ash easily get stuck in the bentonite alkali-adding equipment, resulting in the soda ash being unable to be added into the bentonite normally, and the alkali-adding speed cannot be controlled as needed, resulting in a poor alkali-adding effect. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a bentonite alkali adding device which can crush the soda ash block and conveniently control the alkali adding speed.

[0006] As an improvement, the threads at both ends of the lead screw have opposite rotation directions, and the baffles are located on both sides of the middle of the lead screw.

[0007] As an improvement, the lead screw is rotatably connected to the alkali adding cylinder, and a hand wheel is provided on the surface of the lead screw.

[0008] As an improvement, the moving component includes a frame slidably connected to the alkali adding cylinder, a roller is provided at the bottom of the frame, a screw threadedly connected to the alkali adding cylinder is rotatably connected inside the frame, and a second motor drivingly connected to the screw is provided at one end of the frame.

[0009] As an improvement, the surface of the rotating shaft is provided with conveying blades, and the first motor and the second motor are both electrically connected to a frequency converter.

[0010] As an improvement, the longitudinal section of the frame is in an inverted U shape.

[0011] The beneficial effects of the utility model are:

[0012] The position of the alkali adding cylinder can be easily adjusted by moving the components, so that the soda ash can be released at the desired position for alkali addition.

[0013] The soda ash can be crushed by the crushing assembly, and even if the soda ash absorbs moisture and agglomerates, it will not affect the normal addition of alkali.

[0014] The control component can control the speed of releasing soda ash by controlling the blocking degree of the alkali adding cylinder, thereby controlling the alkali adding speed and achieving a good alkali adding effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

[0022] A bentonite alkali-adding device comprises an alkali-adding cylinder 4, a moving assembly is arranged on the top of the alkali-adding cylinder 4, the moving assembly comprises a frame 5 slidably connected to the alkali-adding cylinder 4, the longitudinal section of the frame 5 is an inverted U-shape, a roller is arranged at the bottom of the frame 5, a screw threadedly connected to the alkali-adding cylinder 4 is rotatably connected inside the frame 5, a second motor drivingly connected to the screw is arranged at one end of the frame 5, a feeding port and a sealing cover 6 matching the feeding port are arranged on the top of the alkali-adding cylinder 4, a crushing assembly is arranged inside the alkali-adding cylinder 4, the crushing assembly comprises a rotating shaft 8 rotatably connected to the alkali-adding cylinder 4, a plurality of crushing knives 9 fixedly connected to the rotating shaft 8, a first motor 7 drivingly connected to the rotating shaft 8 is arranged on the top of the alkali-adding cylinder 4, a control assembly is arranged at the bottom of the alkali-adding cylinder 4, the control assembly comprises a baffle 1 slidably connected to the alkali-adding cylinder 4, and a lead screw 2 threadedly connected to the baffle 1;

[0023] The threads at both ends of the lead screw 2 rotate in opposite directions, the baffles 1 are located on both sides of the middle of the lead screw 2, the lead screw 2 is rotatably connected to the alkali adding cylinder 4, and a hand wheel 3 is provided on the surface of the lead screw 2 to facilitate the rotation of the lead screw 2 and thus drive the two baffles 1 to move.

[0024] Furthermore, a conveying blade 10 is provided on the surface of the rotating shaft 8 to facilitate pushing the soda ash up or down. The first motor 7 and the second motor are both electrically connected to a frequency converter to facilitate controlling the rotation of the first motor 7 and the second motor. An observation window is provided on the surface of the alkali adding cylinder 4 to facilitate observing the internal situation.

[0025] Working principle:

[0026] like Figure 2 As shown, the cover 6 is removed, and a proper amount of soda ash is added into the soda adding cylinder 4 through the feeding port, and then the cover 6 is replaced. The first motor 7 drives the rotating shaft 8 to rotate forward, and the rotating shaft 8 drives the crushing knife 9 and the conveying leaf 10 to rotate forward. The crushing knife 9 crushes the soda ash, and the conveying leaf 10 causes the soda ash below to flip upward. After the crushing is completed, the first motor 7 is turned off.

[0027] The utility model is pushed so that the alkali adding cylinder 4 is located above the bentonite. Figure 4 As shown, the screw 2 is rotated in the positive direction by the hand wheel 3 so that the two baffles 1 are moved away from each other. The blocking degree of the alkali adding cylinder 4 is controlled by controlling the distance between the baffles 1, thereby realizing the control of the alkali adding speed.

[0028] The first motor 7 drives the rotating shaft 8 to rotate in the opposite direction, and the conveying blade 10 pushes the soda ash downward, and the soda ash leaves the alkali adding cylinder 4 to contact and mix with the bentonite. The second motor drives the screw to rotate, and the screw makes the alkali adding cylinder 4 move along the bracket, so as to adjust the alkali adding position, and the frame 5 is pushed to add alkali to the bentonite in a large area. After the alkali adding is completed, the first motor 7 and the second motor are turned off, and the screw 2 is rotated in the opposite direction by the hand wheel 3 to make the two baffles 1 resist each other, so as to block the alkali adding cylinder 4, prevent the internal soda ash from contacting with the outside world, and keep the soda ash dry.

[0029] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
