Description

Technical Field

[0001] The utility model relates to the technical field of equipment for producing and processing emulsion explosives, in particular to a device for filtering and removing waste materials of emulsion explosive matrix. Background Art

[0002] At present, the cooling methods in the production process of emulsion explosives are mainly the cooling of the drug roll and the cooling of the matrix. Among them, the cooling of the matrix is ​​mainly through the cooling of the water tank, that is, after the emulsified matrix is ​​produced, the matrix is ​​spread on the conveyor belt with a certain thickness, and transported in the water tank, and the matrix is ​​cooled from 95℃ to about 50℃ by water. In this process, due to process reasons or other circumstances during the spreading process, small pieces of the matrix fall off. Due to their small size, the small pieces of matrix that fall off are suspended in the water after the temperature drops sharply in the water.

[0003] If these small pieces of substrate are not filtered out, they will affect the subsequent processing steps of the emulsion explosive matrix and the final product quality of the emulsion explosive. At present, there is no equipment that can effectively and quickly filter these small pieces of substrate in the emulsion explosive matrix. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide an emulsion explosive matrix waste filtering and removing device, which can effectively and quickly filter out small pieces of substrate in the emulsion explosive matrix when in use.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is:

[0010] The sieve plate cleaning mechanism cleans the filter residue on the sieve plate on both horizontal sides.

[0011] As an improvement, the screen plate cleaning mechanism includes a strip brush and a reciprocating push-pull mechanism; the bristles of the strip brush are movably connected to the upper surface of the screen plate, and the strip brush is driven by the reciprocating push-pull mechanism disposed in the box body to reciprocate left and right, so as to clean the filter residue on the screen plate from both sides, thereby effectively preventing the screen plate from being blocked as a whole.

[0013] It is worth mentioning that the motor and negative pressure pump used in this technical solution are existing equipment well known to those skilled in the art, and their use and control methods are all existing technologies.

[0014] As an improvement, a transparent observation window is embedded and fixed on the sealed box door, so as to facilitate observation of the filtering condition of the sieve plate, the accumulation of filter residue on the sieve plate, and the accumulation of emulsion explosive matrix under the sieve plate.

[0015] The advantages of the utility model compared with the prior art are:

[0016] 1. When the new type is in use, the small pieces of base material in the emulsion explosive matrix can be effectively and quickly filtered out through the cooperation of the sieve plate and the negative pressure pump, thereby ensuring the subsequent processing procedures of the emulsion explosive matrix and the final product quality of the emulsion explosive.

[0017] 2. When the new model is in use, the design of the screen plate cleaning mechanism allows the filter residue on the screen plate to be cleaned and piled up to the left and right during filtering.

[0023] In the description of the present utility model, it should be understood that the terms "center", "lateral", "up", "down", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more. In addition, the term "including" and any variation thereof are intended to cover non-exclusive inclusions.

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0025] Emulsion explosive matrix waste filtering and rejection device, including:

[0026] The filter box body 1 and the sealed box door 2; Figure 1 As shown, the top of the box body 1 is provided with a feed port 3, the bottom is provided with a discharge port 4 with a discharge valve, a box opening is reserved on the front side, and a cover box opening and a sealed box door 2 are provided on the front side. The setting of the sealed box door 2 on the box body 1 is the prior art. The box body 1 is a square box structure, and support legs 14 are fixed at each corner of the bottom;

[0027] Screen plate 5, such as Figure 2 and 3 As shown, it is installed and fixed in the middle of the box body 1 and is located in the middle of the box opening;

[0028] Negative pressure pump 6, such as Figure 2 and 3 As shown, it is installed and fixed on the side wall of the box body 1, and sucks the air in the inner cavity of the box body 1 under the screen plate 5;

[0029] Screen cleaning mechanism, such as Figure 2 , 3As shown in Figure 4, it includes a strip brush 7, a motor 8, a reciprocating screw 9, a movable seat 10 and a fixed connecting rod 11; the bristles of the strip brush 7 are movably connected to the upper surface of the screen plate 5, and the bristles are hard nylon bristles. The reciprocating screw 9 is rotatably connected between the left and right walls of the box body 1, and after one end extends to the outside of the box body 1, it is driven and connected to the motor 8 installed and fixed on the outer wall of the box body 1. The movable seat 10 is threadedly sleeved on the reciprocating screw 9, and is slidably connected to the top wall of the box body 1 through a slide rail groove 12. The lower side of the movable seat 10 is fixedly connected to the brush handle of the strip brush 7 through a fixed connecting rod 11;

[0030] like Figure 1 As shown, a transparent observation window 13 is embedded and fixed on the sealed box door 2.

[0031] In the specific implementation of this embodiment: the cooled emulsion explosive matrix enters the filter box through the feed port 3 and is filtered by the sieve plate 5. During the process, the negative pressure pump 6 can continuously suck the air in the internal space of the box body 1 below the sieve plate 5, so that its air pressure can be lower than the air pressure in the internal space of the box body 1 above the sieve plate 5, so that the emulsion explosive matrix can be accelerated to pass through the sieve plate 5 and the filtration can be accelerated. At the same time, the operation of the motor 8 will drive the reciprocating screw 9 to rotate at a uniform speed, thereby driving the movable seat 10 and the strip plate brush 7 to reciprocate left and right, and the filter residue on the sieve plate 5 is cleaned and accumulated on the left and right sides thereof; after observing that a large amount of emulsion explosive matrix is ​​accumulated in the lower part of the box body 1 through the transparent observation window 13 (do not let the emulsion explosive matrix contact the sieve plate 5), the operation of the motor 8 and the negative pressure pump 6 is suspended, and then the discharge valve is opened to discharge the filtered emulsion explosive matrix.

[0032] When a lot of filter residues are observed to be accumulated on the left and right sides of the sieve plate 5 through the transparent observation window 13, the sealed box door 2 is opened and the filter residues are manually cleaned out.

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.
