Description
Technical Field
[0001] The present application relates to the technical field of environmental protection, and in particular to a biomass fuel boiler feeding vibration screening device. Background Art
[0002] Biomass boiler is a type of boiler. The boiler that uses biomass energy as fuel is called a biomass boiler. It is divided into biomass steam boiler, biomass hot water boiler, biomass hot air furnace, biomass thermal oil furnace, vertical biomass boiler, horizontal biomass boiler, etc.
[0003] In the prior art, when a biomass boiler is conveying materials through a belt, when a forklift pushes the materials to the feed box, the materials fall unevenly from the feed box to the belt, which can easily cause the belt to be stuck by the materials. Some materials are too long and stuck at the feed port, causing unstable boiler feeding. Therefore, a biomass fuel boiler feeding vibration screening device is needed to solve this problem. Utility Model Content
[0004] In view of the shortcomings of the prior art, the purpose of this application is to provide a biomass fuel boiler feeding vibration screening device to solve the technical problems in the prior art that the belt is easily stuck by materials, and some materials are too long and stuck in the feed port, resulting in unstable boiler feeding.
[0005] The above-mentioned purpose of the present application is achieved through the following technical scheme: a biomass fuel boiler feeding vibration screening device, including a feed box, a filter plate and a vibration device, the filter plate is installed at the feed inlet of the feed box, the filter plate is provided with a plurality of sieve holes, and the vibration device is installed on the feed box and located at the bottom of the filter plate.
[0006] By adopting the above technical scheme, the material is poured into the feed box from the feeding port, so that the material falls onto the filter plate. The material smaller than the sieve hole falls into the filter plate through the sieve hole, the material larger than the sieve hole and too long cannot pass through the sieve hole and remain on the filter plate, and some material smaller than the sieve hole falls between the sieve holes of the filter plate. At this time, the vibration device is started, and the vibration device vibrates the filter plate, so that the material smaller than the sieve hole but falling between the sieve holes of the filter plate is vibrated and falls into the feed box through the sieve hole. This solves the technical problems in the prior art that when the material is pushed into the feed box, the material falls unevenly from the feed box to the belt, which easily causes the belt to be stuck by the material, and some individual materials are too long and stuck in the discharge port, resulting in unstable boiler feeding.
[0007] Furthermore, the vibration device includes a supporting spring, a vibration motor and a cam plate, the supporting spring is arranged between the filter disc and the feed box, one end of the supporting spring is fixedly connected to the feed box, and the other end is fixedly connected to the filter disc, the vibration motor is arranged below the filter disc and fixedly connected to the feed box, the cam plate is fixedly connected to the output end of the vibration motor, and the protrusion of the cam plate can contact the bottom surface of the filter disc.
[0008] By adopting the above technical solution, the vibration device operates as follows: the vibration motor is started, and the output end of the vibration motor rotates to drive the cam plate to rotate. The rotating cam plate protrusion pushes the filter disc upward. At this time, due to the setting of the support spring, the cam plate pushes the protrusion of the filter disc upward, and the cam plate continues to rotate and the protrusion separates from the filter disc. The support spring has been subjected to a certain tensile force when the filter disc moves upward. After the cam plate separates from the filter disc, this tensile force acts on the filter disc, causing the filter disc to vibrate up and down, thereby achieving the purpose of vibrating the filter disc.
[0009] Furthermore, the support spring is provided in multiple positions respectively arranged at the four corners of the filter material disc.
[0010] By adopting the above technical solution, multiple support springs can make the inside of the filter disc more evenly affected by the vibration when the filter disc is vibrated. The support springs arranged at the four corners of the filter disc can radiate the vibration force from the four sides of the filter disc to the middle of the filter disc, making the inside of the filter disc more evenly affected by the vibration.
[0011] Furthermore, the vibration motor and the cam plate are provided with two of them, respectively located on both sides of the filter plate.
[0012] By adopting the above technical solution, the two cam plates lift up the filter material disc from both sides of the filter material disc so that the force applied to it is more uniform, and there will be no situation where one side vibrates more and the other side vibrates less.
[0013] Furthermore, the support spring on one side of the filter disc is higher than the support spring on the opposite side, the feed box is provided with an opening on the side close to the lower support spring, and the filter disc is provided with a discharge port on the side close to the feed box opening.
[0014] By adopting the above technical solution, long rods and materials that do not meet the size of the sieve holes accumulated on the filter disc may block the sieve holes, so that subsequent materials cannot pass through the sieve holes and fall into the feed box. The filter disc is arranged so that the support spring on one side is higher than the support spring on the opposite side. This makes the filter disc installed on the feed box in an inclined posture, which makes the material accumulated on the filter disc fall out of the feed box through the discharge port and the opening as the filter disc is inclined.
[0015] Furthermore, a through groove is provided on the bottom surface of the filter material disc on one side close to the discharge port.
[0016] By adopting the above technical solution, when pouring materials into the feed box, materials smaller than the sieve holes may fall between the sieve holes and fall out of the feed box along with the inclined filter plate. The opening of the through slot solves this problem. Materials smaller than the sieve holes will first fall into the through slot when passing through the discharge port along with the inclined filter plate. At this time, materials smaller than the sieve holes fall into the feed box through the through slot.
[0017] Furthermore, a guide plate is provided on the outer side of the opening of the feed box, one end of the guide plate is fixedly connected to the feed box, and the other end of the guide plate is fixedly connected to the loading box. The guide plate is located at the feed port of the loading box, and the higher end of the guide plate is fixedly connected to the feed box, and the lower end is fixedly connected to the loading box.
[0018] By adopting the above technical scheme, it is very wasteful for long rods and materials that do not meet the size of the sieve holes to fall into and out of the material box after being guided by the inclined filter plate. For this reason, the utility model is provided with a guide plate. After the long rods and materials that do not meet the size of the sieve holes fall into and out of the material box after being guided by the inclined filter plate, they fall on the guide plate and fall into the loading box under the guidance of the guide plate. The loading box collects them for recycling.
[0019] Furthermore, a plurality of groups of stirring blades are arranged in the charging box.
[0020] By adopting the above technical solution, when the long rod and the material that does not meet the size of the sieve hole fall into the loading box, the stirring blade is started, and the stirring blade cuts the material into the size that can pass through the sieve hole, collects the cut material and pours it into the material box.
[0021] In summary, the present application includes at least one of the following beneficial technical effects.
[0022] 1. Through the setting of the feed box, filter disc and vibration device, it is possible to start the vibration motor, pour the material from the feed port of the feed box, let the material fall onto the filter disc, materials smaller than the sieve holes fall through the sieve holes, materials larger than the sieve holes and too long cannot pass through the sieve holes and remain on the filter disc, and some materials smaller than the sieve holes fall between the sieve holes of the filter disc. The vibration motor rotates the convex circular plate to vibrate the filter disc, and materials smaller than the sieve holes but falling between the sieve holes of the filter disc vibrate and fall into the feed box through the sieve holes, reducing the probability of the boiler long rod getting stuck, and achieving the purpose of more uniform and stable material transmission.
[0023] 2. By setting the support spring on one side of the filter disc higher than the support spring on the opposite side and setting the opening and the discharge port, the filter disc is installed on the feed box in an inclined posture. This makes the material accumulated on the filter disc fall out of the feed box through the discharge port and the opening along with the inclined filter disc, thereby preventing the accumulated material from affecting the normal falling of other materials into the feed box.
[0024] 3. Through the setting of the guide plate, the loading box and the stirring blade, the long rods accumulated on the filter plate and the materials that do not meet the size of the sieve holes are guided by the inclined filter plate and fall onto the guide plate, and then fall into the loading box under the guidance of the guide plate. At this time, the stirring blade is started, and the stirring blade cuts the materials into materials that can pass through the sieve holes. The cut materials are collected and poured into the material box, which saves costs. BRIEF DESCRIPTION OF THE DRAWINGS
