Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lightweight mortar production and application equipment, and in particular relates to a mortar discharge dust removal device. Background Technology
[0002] Lightweight mortar is a material made primarily from lightweight aggregates (such as perlite, expanded perlite, and expanded vermiculite), mixed with cement, lime, and other components. Due to the low density of lightweight aggregates, lightweight mortar has a lower density and lighter weight, making it more convenient than ordinary mortar. It is suitable for use in lightweight wall structures such as interior walls, exterior walls, and roofs, as well as for thermal insulation and soundproofing layers, offering advantages in heat insulation, sound insulation, and thermal insulation.
[0003] Currently, lightweight mortar on the market is mainly sold in bags. Processing plants put the well-mixed mortar into storage tanks, and then bag it for storage and sale. In the existing production process, workers open the mouth of the packaging bag and place it over the outlet pipe of the storage tank. The solenoid valve on the outlet pipe opens to allow the mortar to fall. After the mortar has fallen, the conveyor belt below the packaging bag moves it to the sealing machine, where it is sewn shut and the bag is sealed, thus completing the process of discharging and sealing the lightweight mortar.
[0004] However, since lightweight mortar is a powder, it inevitably generates a certain amount of dust during the process of falling from the storage tank, resulting in a dusty working area, poor working environment, and potential occupational disease risks. Utility Model Content
[0005] This utility model addresses the technical problem of dust overflow caused by the discharge of existing lightweight mortar materials by proposing a mortar discharge dust removal device that is reasonably designed, simple in structure, easy to process, and can effectively prevent dust overflow and improve the comfort of the working environment.

The cross-section of the connecting part is circular, and the cross-section of the discharge part is rectangular. A dust suction hood is fitted on the discharge pipe. The dust suction hood extends from the connecting part to the lower middle part of the discharge part. A negative pressure suction pipe is connected to one side of the dust suction hood. A finger cylinder for clamping the packaging bag is provided at the bottom of the dust suction hood. The finger cylinder is located on both sides of the short side of the discharge part. The finger cylinder is slidably located at the bottom of the dust suction hood and slides along the long side of the discharge part.
[0007] As preferred, a push cylinder is installed on the side wall of the dust cover, a mounting seat is connected to the power end of the push cylinder, the finger cylinder is fixed on the mounting seat, and the finger cylinder is slidably arranged on both sides of the short side of the discharge part through the reciprocating movement of the push cylinder.
[0008] As preferred, a guide light axis is further arranged on the side wall of the dust cover, and the guide light axis is arranged through the mounting seat.
[0009] As preferred, a linear bearing matched with the guide light axis is arranged on the mounting seat, and the linear bearing is arranged on the side of the mounting seat away from the dust cover.
[0010] As preferred, a connecting block is arranged on the inner side of the power end of the finger cylinder, and the connecting blocks are oppositely arranged.

Detailed Implementation
[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0022] Example 1, such as Figs. 1-4 As shown, this embodiment aims to solve the dust problem caused by the filling and discharge of existing lightweight mortar. To this end, this embodiment provides a mortar discharge dust removal device, including a discharge pipe 1. In this embodiment, for ease of description, the discharge pipe 1 is set as a connecting part 11 connected to the storage tank and a discharge part 12 for bagging. The above structure is a common existing structure, so it will not be described in detail in this embodiment.
[0023] Considering that the outlet of the existing storage tank is connected to the discharge pipe 1 through a flange, in this embodiment, the cross-section of the connecting part 11 is set to be circular, so that it can be easily connected to the storage tank through the flange. At the same time, the circular connecting part 11 also facilitates the installation of the dust collection cover 2.
[0024] In order to minimize the size of the dust overflow port between the packaging bag and the discharge section 12 when the packaging bag is stretched on both sides, in this embodiment, the discharge section 12 is rectangular in cross-section.
[0025] To achieve dust removal, a dust suction hood 2 is installed on the discharge pipe 1. The dust suction hood 2 is cylindrical with its outlet facing downwards. In this embodiment, for ease of installation, the dust suction hood 2 extends from the connecting part 11 to the lower middle part of the discharge part 12. The main purpose of setting it to the lower middle part of the discharge part 12 is to avoid interfering with the workers' bagging. If the entire discharge part 12 is covered, it will affect the workers' bagging.
[0026] A negative pressure suction pipe 21 is connected to one side of the dust suction cover 2, and the negative pressure suction pipe 21 is connected to a fan, a bag-type dust collector and other equipment to complete the collection of dust.
[0027] In order to reduce the size of the dust overflow port between the packaging bag and the discharge part 12, and facilitate the extraction of dust by the negative pressure suction pipe 21, in this embodiment, a finger air cylinder 3 for clamping the packaging bag is arranged at the bottom of the dust suction cover 2, the finger air cylinder 3 is arranged at both sides of the short side of the discharge part 12, and the finger air cylinder 3 is slidingly arranged at the bottom of the dust suction cover 2 and slidingly arranged along the long side direction of the discharge part 12.
[0028] In this way, after the staff member puts the packaging bag on the discharge part 12 (there is a conveying belt below the packaging bag to support the packaging bag), the finger air cylinder 3 is opened and slides towards the discharge part 12, and when it reaches the designated position, the finger air cylinder 3 works to clamp both sides of the packaging bag, and then the finger air cylinder 3 reverses and tightens the packaging bag. In this way, the long side direction of the packaging bag is tightly attached to the discharge part 12, and the short side direction of the discharge part 12 is narrow, which results in a small dust overflow port formed by the packaging bag and the discharge part 12, and the position is fixed. Therefore, by moving the negative pressure suction pipe 21 close to the two dust overflow ports, effective dust removal can be ensured.
[0029] In order to facilitate the sliding of the finger air cylinder 3, in this embodiment, a push air cylinder 5 is installed on the side wall of the dust suction cover 2. Specifically, in this embodiment, a fixed seat 51 is welded on the side wall of the dust suction cover 2, the fixed seat 51 is arranged in an L shape, the push air cylinder 5 is fixed on the horizontal plate of the fixed seat 51 by bolts, and a mounting seat 4 is connected to the power end of the push air cylinder 5, the mounting seat 4 is also arranged in an L shape, and the finger air cylinder 3 is fixed on the horizontal plate of the mounting seat 4 by bolts. In this way, the finger air cylinder 3 is slidingly arranged at both sides of the short side of the discharge part 12 through the reciprocating movement of the push air cylinder 5.
[0030] In order to ensure the stability of the sliding of the mounting seat 4, a guide light shaft 22 is arranged on the side wall of the dust suction cover 2, and the guide light shaft 22 passes through the mounting seat 4. At the same time, in order to reduce friction, a linear bearing 41 is arranged on the mounting seat 4 and matched with the guide light shaft 22. In order to avoid the linear bearing 41 affecting the moving distance of the mounting seat 4 and causing interference, in this embodiment, the linear bearing 41 is arranged on the side of the mounting seat 4 away from the dust suction cover 2.
[0031] Considering that the finger cylinder 3 holds the packaging bag, the thickness of the packaging bag is limited, and the distance between the two power ends of the existing finger cylinder 3 is much larger than the thickness of the packaging bag. Therefore, in the embodiment, a connecting block 31 is arranged on the inner side of the power end of the finger cylinder 3, and the two connecting blocks 31 are arranged opposite to each other. At the same time, a rubber block 32 is arranged on the inner side of the connecting block 31, and a friction groove is arranged on the inner side of the rubber block 32, and the friction grooves are uniformly distributed on the inner side of the rubber block 32. In this way, through the arrangement of the connecting block 31 and the rubber block 32, it can be ensured that the packaging bag can be held, so as to complete the tensioning of the two sides of the packaging bag.
[0032] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification of the above embodiments made according to the technical essence of the present application without departing from the technical scheme of the present application still belongs to the protection scope of the technical scheme of the present application.
